There are a number of '''methods of evolution''', which defines how and when a Pokémon evolves. These can make it slightly harder for some Pokémon to evolve in comparison to others.
There are numerous '''methods of Evolution''' which define how and when {{OBP|Pokémon|species}} [[Evolution|evolve]]. Most Pokémon will evolve by leveling up while others evolve through specific means, such as being traded, achieving a certain amount of friendship or leveling at certain times, among others.


==By level==
==In the core series games==
Most evolutions happen by a Pokémon achieving a certain [[level]].  A Pokémon earns levels by gaining [[experience]] points from a battle.  A detailed explanation on how experience points work is listed under the "Experience" page.
In the [[core series]] games, Pokémon normally only evolve after one of three events:
*[[List of Pokémon that evolve at or above a certain level|Gaining a level]]
*{{cat|Pokémon that evolve by using an item|Being exposed to an item}} (such as an [[Evolution stone]])
*{{cat|Pokémon that evolve through trading|Being traded}}


A {{i|Rare Candy}} can make a Pokémon instantly gain a level, potentially getting the Pokémon one step closer to evolving.  If a Rare Candy is used to move a Pokémon to the level at which it would evolve through Experience alone, the Pokémon will evolve; level-based evolution is not discriminatory with respect to how a Pokémon attains its level.
Prior to [[Generation VIII]], the above were the only triggers to evolve Pokémon. However, {{g|Sword and Shield}} introduced four new triggers, each only used by a very select few Pokémon species:
*Spinning and striking a pose with the Pokémon in the party
*The Pokémon performing a specific action in battle
*Traveling through a specific location with the Pokémon in the party
*Observing a specific object in a specific location with the Pokémon in the party


A few exceptions to this method include the [[Pokémon Daycare]] and using an {{i|Everstone}}. Pokémon will not evolve regardless of level in the Daycare or by using an Everstone.  Therefore, it is safe to say that, for the game's purposes, only Pokémon in a trainer's active [[party]] will evolve, if they are not holding an Everstone.
When the appropriate trigger occurs, if the Pokémon meets the requirements to evolve, it will do so. However, if a Pokémon meets the trigger in battle, it will only evolve after the battle ends.


Level evolution is not limited to the normal level at which Pokémon evolve. A Pokémon will try to evolve if it is allowed to at higher levels, but the evolution level commonly listed is the lowest possible level at which the evolution will take place.
The [[Everstone]] prevents a Pokémon's Evolution:
*In Generation II, a Pokémon holding an Everstone (including Kadabra) cannot evolve by any method.
*In Generation III, trade Evolutions are affected by the {{DL|List of glitches in Generation III|held item loss glitch}}: if {{p|Kadabra}}, {{p|Machoke}}, {{p|Graveler}}, or {{p|Haunter}} is traded while holding any item (including an Everstone), that Pokémon will evolve and its held item will be permanently lost.
*From [[Generation IV]] onwards, the Everstone does not prevent a Pokémon evolving via [[Evolution stone]]. It also fails to prevent {{p|Kadabra}} from evolving.
*If either {{p|Karrablast}} or {{p|Shelmet}} holds an Everstone when traded for the other, neither can evolve.


'''Example''': {{p|Ekans}} evolves into {{p|Arbok}} at <b>level 22</b>.
===Leveling up===
[[Level]]ing up is the most common trigger for Evolution. Evolution by level up can be triggered by gaining [[experience]] in battle or by using a [[Rare Candy]]; leveling up in [[Pokémon Day Care]] or [[PokéPelago|Isle Evelup]] will not trigger Evolution, although Pokémon leveled up in these ways can still evolve if leveled up by battle or a Rare Candy afterwards. All Pokémon that evolve by leveling up have at least one requirement that must be met when leveled up in order to evolve, the most common being that the Pokémon must be at least a specific level after leveling up. Other requirements include knowing a specific move, being in a specific location, or holding a specific item. A Pokémon that meets its level-up Evolution requirements will always attempt to evolve when it is leveled up in battle or by using a Rare Candy, regardless of whether it had previously been prevented from evolving.


==By evolutionary stone==
If a Pokémon levels up in battle, it will not evolve until the battle is over. A Pokémon can only evolve once after a battle or consuming a Rare Candy, even if it gained multiple levels. Even if a Pokémon is fainted at the end of the battle, if it leveled up when it met its Evolution requirements during the battle, it will still evolve, but will not be revived from [[fainting]]. However, prior to [[Generation VI]], the player's Pokémon would not evolve if player lost the battle, even if its Evolution requirements were met.
Some Pokémon will only evolve after being exposed to an [[evolutionary stone]].


If a Pokémon's next stage requires the use of a stone, then it can be applied at any time, this causing instant evolution.
Starting in [[Generation VIII]], if a [[Rare Candy]] is used on a level 100 Pokémon that evolves by leveling up and currently meets its Evolution requirements, it will evolve (without gaining a level).


However, once exposed to an element stone, most Pokémon can no longer learn any more [[moves]] by leveling up.  There are exceptions to this rule, however, and certain moves are exclusive to the stone-evolved Pokémon.
In {{g|Legends: Arceus}}, Evolution can be performed at any time as long as the conditions are met, instead of requiring a level up.


'''Example''': {{p|Nidorino}} evolves into {{p|Nidoking}} by being exposed to a {{i|Moon Stone}}.
====At or above a certain level====
{{main|Level-based Evolution}}
Most Pokémon evolve when they reach or surpass a certain level. Once such a Pokémon has reached the required level, unless there are other requirements for its Evolution, it will attempt to evolve after every battle in which it levels up and every time it gains a level from a Rare Candy.


==By trading==
{| style="margin:auto; text-align:center; {{roundy}} border: 2px solid #{{grass color dark}}; background: #{{grass color}};"
Some species can only be gotten by being [[trade]]d to another trainer; as soon as a Pokémon is transferred the evolution process immediately begins. The trade may be facilitated by either a [[link cable]] or [[wireless adapter]], or an in-game trade between the player and a non-player character.

A famous mistranslation in the [[Generation I]] games suggested that after trading a woman a {{p|Raichu}}, she said that it had evolved.  This fueled speculation as to whether or not there would be a third stage to the {{p|Pikachu}} line in [[Generation II]]; the third stage was realized in the form of a [[Baby Pokémon]], {{p|Pichu}}.
====When friendship is high====
{{main|Friendship Evolution}}
Some Pokémon evolve when they are leveled up with a [[friendship]] of at least 220. Like friendship itself, this evolutionary requirement was introduced in [[Generation II]]. As long as the Pokémon has the required amount of friendship, unless there are other requirements for its Evolution, it will attempt to evolve whenever it levels up by battle or Rare Candy.


'''Example''': {{p|Graveler}} evolves into {{p|Golem}} by being traded.
[[Baby Pokémon]] often have this Evolution requirement, but it is also an Evolution requirement for other Pokémon, and not all baby Pokémon have this as an Evolution requirement.


==By trading with an item==

| style="{{roundy}} background: #{{flying color light}}" | [[File:176Togetic.png|96px]]<br>{{pcolor|Togetic|{{flying color dark}}}}
|}{{-}}


In the case of some species, it is not enough just to trade them. They must also be given a particular item to hold.
====When the Pokémon knows a certain move====
:''See also: [[:Category:Pokémon that evolve with certain moves]]''
Some Pokémon evolve when they are leveled up and know a certain move or certain type of move. This evolutionary requirement was introduced in [[Generation IV]].


This was introduced in [[Generation II]] when some already existing Pokémon were given new evolutionary forms.
If the Pokémon learns the required move by leveling up, that same level up can trigger the Evolution. However, if a Pokémon learns a move by level up and overwrites the required move, such that it no longer knows the required move at the end of the battle (or after completing the level up in the case of a Rare Candy), it cannot evolve.


'''Example:''' {{p|Onix}} evolves into {{p|Steelix}} by being traded when it is holding a [[Items#Metal Coat|Metal Coat]].
These moves are commonly available by leveling up, although some are only learned at level 1, so they normally must be taught by the [[Move Reminder]].


==By happiness==
{| style="margin:auto; text-align:center; {{roundy}} border: 2px solid #{{ground color}}; background: #{{ice color}};"
There comes a time when the only way for a Pokémon to evolve is through making it especially [[happiness|happy]].  This is usually true for [[baby Pokémon]] such as {{p|Cleffa}}, but also holds true for some other Pokémon, including {{p|Chansey}} (evolves to {{p|Blissey}}).
|-

|-
| style="{{roundy}} background: #{{ground color light}}" | [[File:221Piloswine.png|96px]]<br>{{pcolor|Piloswine|{{ground color dark}}}}

| style="{{roundy}} background: #{{ground color light}}" | [[File:473Mamoswine.png|96px]]<br>{{pcolor|Mamoswine|{{ground color dark}}}}
|}{{-}}


Once a Pokémon's hidden happiness stat hits 220, it will evolve on the next level-up.
====In certain locations====
{{main|Location-based Evolution}}
Some Pokémon evolve when they are leveled up in certain locations. This evolutionary requirement was introduced in [[Generation IV]].


'''Example''': {{p|Golbat}} evolves into {{p|Crobat}} through being happy.
There are four different types of location that can trigger location-based Evolutions: [[Moss Rock]], [[Ice Rock]], [[special magnetic field]], and [[Mount Lanakila]]. Mount Lanakila, which is only required for {{p|Crabrawler}}'s Evolution, is the only one which is a specific location rather than a type of location.


==Others==
{{game|HeartGold and SoulSilver|s}} lack the locations needed for location-based Evolutions, making them impossible within those games. Starting in [[Generation VIII]], although some games still feature location-based Evolution and others do not, it is possible to instead use [[Evolution stone]]s to evolve these Pokémon (except for {{p|Nosepass}} and {{p|Eevee}}'s Evolutions into {{p|Probopass}} and {{p|Glaceon}} respectively in {{g|Brilliant Diamond and Shining Pearl}}).
'''By Beauty'''
A single Pokémon makes use of a condition stat, the beauty stat. That Pokémon is {{p|Feebas}}. After its beauty stat reaches 170 and the Pokémon gains an additional level, it will evolve into a {{p|Milotic}}.


'''By Attack & Defense'''
{| style="margin:auto; text-align:center; {{roundy}} border: 2px solid #{{steel color}}; background: #{{rock color}};"
{{p|Tyrogue}} has an odd three-way branched evolution depending on its stats when it reaches level 20.
|-

|}{{-}}


*Evolves into {{p|Hitmonchan}} if defence is higher than attack.
====In a certain region====
*Evolves into {{p|Hitmonlee}} if attack is higher than defence.
{{main|Region-based Evolution}}
*Evolves into {{p|Hitmontop}} if defence is equal to attack.
Some Pokémon evolve when they are leveled up in a specific [[region]]. This evolutionary requirement was introduced in [[Generation VII]].


'''By Personality Value'''
Pokémon that evolve this way may also need other conditions, such as requiring it to be a specific time of day. Some Pokémon evolve into different forms depending on what region they are in.
{{p|Wurmple}}'s evolution into either {{p|Cascoon}} or {{p|Silcoon}} is based on its [[Personality_value#Wurmple's_evolution|personality value]], which is dictated when the Wurmple is caught.


'''By Empty Slot & [[Poké Ball]]'''
{| style="margin:auto; text-align:center; {{roundy}} border: 2px solid #{{poison color dark}}; background: #{{poison color}};"
The method of receiving a {{p|Shedinja}} is perhaps the oddest form of evolution, to the point that it can scarcely be called an evolution. Once a {{p|Nincada}} reaches level 20 it will evolve into a {{p|Ninjask}}, however, if the player has a free party slot and an extra [[Poké Ball]] in his/her bag at the time, a {{p|Shedinja}} will fill that slot upon Nincada's evolution.

'''By Time & Tameness'''
====At certain times====
Also, {{p|Espeon}} and {{p|Umbreon}} will evolve depending on the in-game clock. The {{p|Eevee}} it evolves from evolves by happiness.
{{main|Time-based Evolution}}
Some Pokémon evolve when they are leveled up at a certain time of day. Like the [[time]] mechanic itself, this evolutionary requirement was introduced in [[Generation II]].


'''By Time & Happiness'''
The time of day is only ever one of several requirements, never the only one. Other requirements it is combined with include having high [[friendship]] or holding a specific [[held item]].
In the fourth generation a new method of evolution was added. A Pokémon will evolve when it is happiest during a certain part of the day. The following Pokémon are known to evolve this way:
*{{p|Subomie}}- Happiness during the day - {{p|Roselia}}
*{{p|Lisyan}}- Happiness during the day - {{p|Chimecho}}
*{{p|Riolu}}- Happiness during the night - {{p|Lucario}}


'''By Gender'''
Due to the lack of a time system in {{game|FireRed and LeafGreen|s}}, Pokémon whose Evolution depends on the time cannot evolve.
Some Pokémon evolve at a certain level but must be either male of female. The following Pokémon evolve using this method :
*{{p|Minomutchi}}♀ - at level 20 - {{p|Minomadam}}
*{{p|Minomutchi}}♂ - at level 20 - {{p|Garmeil}}
*{{p|Mitsuhoney}}♀ - at level 25 - {{p|Beequeen}}


'''By Gender with hold items'''
In {{g|Sword and Shield}}, time is pre-set outside the [[Wild Area]] before becoming {{pkmn|Champion}}. This also influences Evolution.
Some Pokémon can only evolve when they are a certain gender and are holding an item. The following Pokémon evolve in this way :
*{{p|Kirlia}}♂ - holding an awakening stone - {{p|Erlade}}
*{{p|Snorunt}}♀ - holding an awakening stone - {{p|Yukimenoko}}


'''By [[Move]]s learned'''
{| style="margin:auto; text-align:center; {{roundy}} border: 2px solid #{{dragon color}}; background: #{{rock color}};"
Some Pokémon evolve when they level up while knowing a certain move. The following Pokémon evolve using this method:
|-
*{{p|Lickitung}} - {{p|Berobelt}}: Level up knowing the move "Rollout"
! colspan="3" | At certain times
*{{p|Tangela}} - {{p|Mojumbo}} , {{p|Yanma}} - {{p|Megayanma}} , and

*{{p|Mime Jr.}} - {{p|Mr.Mime}} , and {{p|Bonsly}} - {{p|Sudowoodo}}: Both evolve when leveled up knowing the move "Mimic"
| style="{{roundy}} background: #{{dragon color light}}" | [[File:697Tyrantrum.png|96px]]<br>{{pcolor|Tyrantrum|{{dragon color dark}}}}
|}{{-}}


'''By area trained at'''
The specific times in each game that count as day and night for Evolutions are detailed in the table below.
Some Pokémon evolve when they level up in a certain area. The following Pokémon evolve in this way:

*{{p|Magneton}} - {{p|Jibacoil}} : Level up in the Tengan Mountain Range
====While holding an item====
*{{p|Nosepass}} - {{p|Dainose}} : Level up in the Tengan Mountain Range
:''See also: [[:Category:Pokémon that evolve by leveling up with a held item]]''
*{{p|Eevee}} - {{p|Glacia}} : Level up next to the Ice Rock on Route 217
Some Pokémon evolve when they are leveled up while holding a specific [[Evolution item]]. If a Pokémon evolves this way, the item disappears upon completion of the Evolution; the item is not consumed if the Evolution is cancelled. This evolutionary requirement was introduced in [[Generation IV]].
*{{p|Eevee}} - {{p|Leafia}} : Level up next to the Moss Rock in Hakutai Forest


All Pokémon that evolve this way also require that they be leveled up at a specific time of day to be evolved.

====If the Pokémon is a certain gender====
{{main|Gender-based Evolution}}
The Evolution of some Pokémon that evolve when they are leveled up is dependent on the Pokémon's gender. This evolutionary requirement was introduced in [[Generation IV]].
 
{{p|Combee}} and {{p|Salandit}} can evolve only if they are [[Gender|female]] (males cannot evolve). {{p|Burmy}} evolves into either {{p|Mothim}} or {{p|Wormadam}}, depending on whether it is male or female, respectively.

====In a certain game====
:''See also: [[:Category:Pokémon that evolve based on game]]''
The Evolution of {{p|Rockruff}} and {{p|Cosmoem}} is dependent on the game they are leveled up in. This evolutionary requirement was introduced in [[Generation VII]].
 
Cosmoem will evolve into either {{p|Solgaleo}} or {{p|Lunala}} depending on the game it is leveled up in. {{p|Rockruff}} will always evolve into {{p|Lycanroc}}, but, prior to [[Generation VIII]], Lycanroc's form depends on the game Rockruff was evolved in, and Rockruff's Evolution can only occur at certain times of day (Midday Form requires it be daytime while Midnight Form requires it be nighttime); furthermore, special Rockruff that have {{a|Own Tempo}} can only evolve into Dusk Form Lycanroc, which is not dependent on the game. Starting in [[Generation VIII]], the form Lycanroc becomes is no longer version-exclusive.

====Unique conditions====
:''See also: [[:Category:Pokémon that evolve through a unique method]]''
The following Pokémon evolve through a method that is isolated to their Evolution line only.
 
* In {{g|XD: Gale of Darkness}} only, {{p|Eevee}} evolves into {{p|Espeon}} or {{p|Umbreon}} when leveled up with a [[Sun Shard]] or [[Moon Shard]], respectively, in the player's [[Bag]]. Only one of the two items can be obtained per game.
* Eevee evolves into {{p|Sylveon}} when leveled up while knowing a {{type|Fairy}} move and having at least two levels of [[affection]]<sup>{{gen|VI}}—{{gen|VII}}</sup> or high friendship<sup>{{gen|VIII}}+</sup>.
* {{p|Mantyke}} evolves into {{p|Mantine}} when leveled up with a {{p|Remoraid}} in the player's party.
* {{p|Feebas}} evolves into {{p|Milotic}} when leveled up with its {{OBP|Beautiful|condition|Beauty}} [[Contest condition|condition]] at 170 or above. Starting from [[Generation V]], it also evolves into Milotic when [[trade]]d while holding a [[Prism Scale]].
* When {{p|Nincada}} evolves into {{p|Ninjask}} (which it does starting at level 20), if there is an empty slot in the party, a {{p|Shedinja}} will appear. From [[Generation IV]] onward, the player must also have a spare standard {{i|Poké Ball}} in their Bag.
* {{p|Pancham}} evolves into {{p|Pangoro}} starting at level 32 if there is a {{type|Dark}} Pokémon in the party.
* {{p|Inkay}} evolves into {{p|Malamar}} starting at level 30 when leveled up while the game system is held upside-down. On the [[Nintendo Switch]], this can only be accomplished in handheld mode.
* {{p|Sliggoo}} evolves into {{p|Goodra}} starting at level 50 during [[rain]] (or [[fog]]<sup>{{gen|VII}}-{{gen|VIII}}</sup>) in the overworld. (Rain that is only present in battle will not trigger the Evolution.)
** In [[Hisui]], Sliggoo evolves into {{rf|Hisuian}} Goodra starting at level 50 during rain or fog in the overworld.
* {{p|Finizen}} evolves into {{p|Palafin}} starting at level 38 when leveled up while connected with another player via the [[Union Circle]].
* {{p|Bisharp}} evolves into {{p|Kingambit}} when leveled up after defeating three Bisharp that hold a [[Leader's Crest]].
* {{p|Gimmighoul}} evolves into {{p|Gholdengo}} when leveled up while the player has 999 [[Gimmighoul Coin]]s in their Bag. This consumes the Gimmighoul Coins, and the Evolution cannot be canceled.
 
====Additional factors====
Some Pokémon with branched Evolutions can evolve into one of multiple different Pokémon or different forms of the same Pokémon depending on other factors, but still have the same Evolution requirements for all of these possibilities.
 
*{{p|Burmy}} evolves starting at level 20, but its evolved form is determined by its gender and, if female, its cloak. As Burmy, its cloak changes according to the place where it last battled but has no effect on Burmy itself; once it evolves into Wormadam, its cloak no longer changes, and its types and the moves it can learn are dependent on its cloak.
**Male Burmy → {{p|Mothim}}
**Female Burmy → {{p|Wormadam}}
***Female Plant Cloak Burmy → Plant Cloak Wormadam ({{t|Bug}}/{{t|Grass}})
***Female Sandy Cloak Burmy → Sandy Cloak Wormadam ({{t|Bug}}/{{t|Ground}})
***Female Trash Cloak Burmy → Trash Cloak Wormadam ({{t|Bug}}/{{t|Steel}})
 
*{{p|Tyrogue}} evolves starting at level 20, depending on its stats.
**{{p|Hitmonlee}} if Attack > Defense
**{{p|Hitmonchan}} if Attack < Defense
**{{p|Hitmontop}} if Attack = Defense
 
*{{p|Wurmple}} evolves into {{p|Silcoon}} or {{p|Cascoon}} starting at level 7, depending on its [[personality value]]. It is a hidden value determined when the Pokémon is encountered and cannot be seen or affected by the player.
 
*{{p|Dunsparce}} evolves into {{p|Dudunsparce}} when leveled up while knowing {{m|Hyper Drill}}. The form of Dudunsparce it evolves into depends on its [[personality value|encryption constant]]. Since this value cannot be influenced or seen by the player, what a given Dunsparce will evolve into is essentially random — with a 1/100 chance of evolving into [[List of Pokémon with form differences#Dudunsparce|Three-Segment Form]] Dudunsparce.
 
*{{p|Tandemaus}} evolves into {{p|Maushold}} starting at level 25, but if Tandemaus is not sent out in the battle it levels up in, the Evolution animation will be skipped. The form of Maushold it evolves into depends on its [[personality value|encryption constant]]. Since this value cannot be influenced or seen by the player, what a given Tandemaus will evolve into is essentially random — with a 1/100 chance of evolving into [[List of Pokémon with form differences#Maushold|Family of Three]] Maushold.
 
===Using an item===
Some Pokémon evolve when they are exposed to a specific item. The player can use one of these items on a compatible Pokémon at any time outside of battle, which consumes the item. From Generation IV onwards, Evolution by exposure to an item cannot be prevented by holding an [[Everstone]]. Due to being able to evolve at any time, these Pokémon usually learn fewer or no moves by level up after evolving; however, in Generation VIII, even if they do not learn any additional moves by level-up, they normally can still be taught any move their pre-evolved form could learn by level up by the [[Move Reminder]].
 
In {{g|Legends: Arceus}} only, Pokémon that would normally evolve while holding a particular item (including by leveling up while holding a specific item) instead evolve when exposed to that item.

====Evolution stone====
{{main|Evolution stone}}
:''See also: [[:Category:Pokémon that evolve by Evolution stone]]''
The most common type of item that can trigger this kind of Evolution is an Evolution stone (and was the only type that could, prior to [[Generation VIII]]). Despite its name, the [[Oval Stone]] is not an Evolution stone, because it triggers Evolution as a [[held item]] rather than by being used directly.

=====If the Pokémon is a certain gender=====
{{main|Gender-based Evolution}}
While most Pokémon that evolve by Evolution stone have no additional requirements, some Pokémon that evolve this way can only evolve if they are a specific gender. This evolutionary requirement was introduced in [[Generation IV]].
 
The only two Evolutions with this requirement are {{p|Kirlia}}'s Evolution into {{p|Gallade}} (which requires that it be male) and {{p|Snorunt}}'s Evolution into {{p|Froslass}} (which requires that it be female). These two Evolutions are the only Evolutions to use the [[Dawn Stone]].

=====In a certain region=====
{{main|Region-based Evolution}}
While most Pokémon that evolve by Evolution stone have no additional requirements, some Pokémon can evolve into a different form when they use an Evolution stone in a specific [[region]]. This evolutionary requirement was introduced in [[Generation VII]].

====Special items====
The following items are each only used by one Pokémon to evolve.
 
*{{rf|Galarian}} {{p|Slowpoke}} evolves into {{rf|Galarian}} {{p|Slowbro}} when exposed to a [[Galarica Cuff]]
*{{rf|Galarian}} {{p|Slowpoke}} evolves into {{rf|Galarian}} {{p|Slowking}} when exposed to a [[Galarica Wreath]]

*Artisan Form {{p|Poltchageist}} evolves into Masterpiece Form {{p|Sinistcha}} when exposed to a [[Masterpiece Teacup]]
*{{p|Duraludon}} evolves into {{p|Archaludon}} when exposed to a [[Metal Alloy]]
 
===Trading===
{{main|Trade Evolution}}
Some Pokémon evolve when they are [[trade]]d. The Evolution starts immediately after the trade is completed, regardless of the method of trading used. However, sometimes there are additional conditions.
 
In the {{pkmn|animated series}}, Pokémon that evolve by trade sometimes evolve after being temporarily in a different person's possession, like [[Misty's Politoed]] being with [[Nurse Joy]] at the [[Pokémon Center]] and [[Brock's Steelix]] when he lent Onix to his brother [[Forrest]].

====Trade holding a certain item====
:''See also: [[:Category:Pokémon that evolve by trading with a held item]]''
Some Pokémon evolve when traded while holding a specific [[Evolution item]]. If a Pokémon evolves this way, the item disappears upon completion of the Evolution. This method of Evolution was introduced in [[Generation II]] (the same generation that introduced held items in general).
 
In {{g|Legends: Arceus}}, Pokémon that evolve when traded while holding a specific item can be evolved without trading by using their Evolution item from the player's satchel.

====Trading for a certain Pokémon====
Some Pokémon evolve when traded with a specific Pokémon. Only two Pokémon do this so far and evolve each other through this method. This method of Evolution was introduced in [[Generation V]]. If either Pokémon holds an [[Everstone]], neither can evolve.

===Unique triggers===
[[Generation VIII]] introduced several unique triggers for newly introduced Pokémon and [[regional form]]s. These triggers are all exclusive to a single Pokémon.
 
* {{rf|Galarian}} {{p|Farfetch'd}} evolves into {{p|Sirfetch'd}} after it lands three [[critical hit]]s in a single battle.
* {{rf|Galarian}} {{p|Yamask}} evolves into {{p|Runerigus}} when the player travels through the stone gate in the [[Dusty Bowl]] after it has lost 49 {{stat|HP}} or more from a single attack and did not [[fainting|faint]] in the same battle or since.
* {{p|Milcery}} evolves into {{p|Alcremie}} when the player spins and strikes a pose while Milcery holds a [[Sweet]]. Unless Milcery is {{Shiny}}, Alcremie's color depends on the [[Time-based Evolution|time]] of day, the length of the spin, and the direction of the spin; if Milcery is {{Shiny}}, Alcremie takes on its sole Shiny coloration. Alcremie's Sweet corresponds to the Sweet Milcery held. Milcery evolves into:
<!--Do NOT change the order of the forms, this is the official order.-->
** Vanilla Cream Alcremie after spinning clockwise for less than 5 seconds during the day.
** Ruby Cream Alcremie after spinning counterclockwise for less than 5 seconds during the day.
** Matcha Cream Alcremie after spinning clockwise for less than 5 seconds at night.
** Mint Cream Alcremie after spinning counterclockwise for more than 5 seconds at night.
** Lemon Cream Alcremie after spinning clockwise for more than 5 seconds at night.
** Salted Cream Alcremie after spinning counterclockwise for less than 5 seconds at night.
** Ruby Swirl Alcremie after spinning counterclockwise for more than 5 seconds during the day.
** Caramel Swirl Alcremie after spinning clockwise for more than 5 seconds during the day.
** Rainbow Swirl Alcremie after spinning counterclockwise for more than 10 seconds during the evening (between 7 and 7:59 PM in real-time in {{g|Sword and Shield}}).
* {{p|Kubfu}} evolves into {{p|Urshifu}} when shown the scroll in one of the [[Towers of Two Fists]]. The {{DL|List of Pokémon with form differences|Urshifu|form}} it evolves into depends on the tower it is trained in. In {{g|Scarlet and Violet}}, Kubfu instead uses a specific Scroll to evolve. Unlike most Evolution items, the Scroll is not consumed after use.
** Kubfu evolves into Urshifu Single Strike Style when trained in the [[Tower of Darkness]]. In Pokémon Scarlet and Violet, Kubfu evolves into Urshifu Single Strike Style when exposed to the [[Scroll of Darkness]].
** Kubfu evolves into Urshifu Rapid Strike Style when trained in the [[Tower of Waters]]. In Pokémon Scarlet and Violet, Kubfu evolves into Urshifu Rapid Strike Style when exposed to the [[Scroll of Waters]].
* {{p|Stantler}} evolves into {{p|Wyrdeer}} after using {{m|Psyshield Bash}} in the [[Move mastery|agile style]] at least 20 times. In Pokémon Scarlet and Violet, Stantler cannot evolve (it is programmed to evolve when leveled up after using Psyshield Bash at least 20 times, but this Evolution method is disabled).
* {{DL|List of Pokémon with form differences|Basculin|White-Striped}} {{p|Basculin}} evolves into {{p|Basculegion}} after losing at least 294 {{Stat#HP|HP}} from [[Recoil|recoil damage]], not counting damage that results in it fainting. In Pokémon Scarlet and Violet, White-Striped Basculin must level up after losing at least 294 HP from recoil damage in order to evolve.
* {{rf|Hisuian}} {{p|Qwilfish}} evolves into {{p|Overqwil}} after using {{m|Barb Barrage}} in the [[Move mastery|strong style]] at least 20 times. In Pokémon Scarlet and Violet (starting in Version 3.0.0), Hisuian Qwilfish evolves when leveled up while knowing Barb Barrage.
* {{p|Primeape}} evolves into {{p|Annihilape}} when leveled up after using {{m|Rage Fist}} at least 20 times.
 
===Can only evolve in other games===
{{p|Meltan}}, which first appeared in the core series games in [[Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!]], cannot be evolved in the core series games. Instead, it can only be evolved in {{g|GO}}, where it can be evolved by pressing the "Evolve" button on Meltan's profile screen and spending 400 Meltan {{OBP|Candy|GO}}.

==In the side series games==
===Pokémon Colosseum and XD: Gale of Darkness===
In {{g|Colosseum}} and {{XD}}, there is no time system:
 
* In Colosseum, Pokémon whose Evolution depends on the time cannot evolve.
* In XD, Evolutions that depend on the time of day instead depend on the [[Sun Shard]] and [[Moon Shard]].
 
==In the spin-off games==
{{incomplete|section|needs=Mystery Dungeon}}
===Pokémon GO===
{{main|List of Pokémon by evolutionary line in Pokémon GO}}
In {{g|GO}}, the only way to evolve Pokémon is to press the "Evolve" button on that Pokémon's profile page. All Pokémon require the player spend a specific amount of their own {{OBP|Candy|GO}} to evolve them, but some have additional requirements.
 
Some Evolutions require an item in addition to the Candy cost. All Evolutions that require an [[Evolution item]] other than an [[Evolution stone]] (except {{p|Feebas}} and {{p|Clamperl}}) or [[Sun Stone]] to evolve in the core series require an item to be spent in Pokémon GO. For Evolutions introduced in Generation II, the item required is the same as in the core series. All [[cross-generational evolutions]] introduced in [[Generation IV]], except location-based Evolutions, require a [[Sinnoh Stone]] to evolve. All Evolutions introduced in Generation V that require an Evolution stone in the core series (except a Sun Stone) require a [[Unova Stone]] in Pokémon GO; Generation V Evolutions that require a Sun Stone in the core series also require it in Pokémon GO.
 
From January 10, 2020 onward, certain Pokémon do not cost any Candy to evolve if they are traded. These Pokémon are {{p|Kadabra}}, {{p|Machoke}}, {{p|Graveler}}, {{p|Haunter}}, {{p|Boldore}}, {{p|Gurdurr}}, {{p|Karrablast}}, {{p|Shelmet}}, {{p|Pumpkaboo}}, and {{p|Phantump}}.
 
{{p|Feebas}}, {{p|Bonsly}}, {{p|Mime Jr.}}, {{p|Happiny}} and {{p|Woobat}} cannot be evolved until the player has walked with them as [[Buddy Pokémon]] for a sufficient distance (the specific distance varies between species). This requirement is noted under the "Evolve" button.
 
For some species of Pokémon with branched Evolutions, there are multiple "Evolve" buttons, allowing the player to choose which Pokémon to evolve into. The different buttons may have different requirements, such as one button requiring an item while another does not.
 
Despite having branched Evolutions, {{p|Eevee}}, {{p|Tyrogue}}, {{p|Wurmple}}, and {{p|Clamperl}} only have a single button. Some of them have no indication of which Pokémon it will evolve into in most cases.
*Normally, if the player evolves Eevee, it will randomly evolve into one of {{p|Vaporeon}}, {{p|Jolteon}}, and {{p|Flareon}}. However, if the player meets a special requirement, the player can influence its Evolution.
**If the player is in range of a [[Mossy Lure Module]] or [[Glacial Lure Module]], Eevee will evolve into Glaceon or Leafeon, respectively. In this case, the Evolution button will indicate which Pokémon Eevee will evolve into.
**Once per nickname, if an Eevee has one of several special [[nickname]]s when evolved, it will evolve into a specific Pokémon. If the Eevee is nicknamed "{{DL|Eevee brothers|Rainer}}", "{{DL|Eevee brothers|Sparky}}", "{{DL|Eevee Brothers|Pyro}}", "[[Sakura]]", "{{DL|Kimono Girl|In the anime|Tamao}}", "{{DL|Eevee users|Leafeon User Linnea|Linnea}}", "{{DL|Eevee users|Glaceon User Rea|Rea}}", or "{{DL|Eevee users|Sylveon User Kira|Kira}}" it will evolve into Vaporeon, Jolteon, Flareon, Espeon, Umbreon, Leafeon, Glaceon, or Sylveon, respectively. Once the player has evolved an Eevee using one of these nicknames, that nickname will no longer have any impact on Eevee's Evolution.
**If Eevee is currently the [[Buddy Pokémon]] and has obtained at least 2 Candy for the player, it will evolve into {{p|Espeon}} during Day Mode or {{p|Umbreon}} during Night Mode.
*The Pokémon {{p|Tyrogue}} evolves into depends on its highest {{IV}}. It will evolve into {{p|Hitmonlee}} if it is Attack, {{p|Hitmonchan}} if it is Defense, or {{p|Hitmontop}} if it is HP. Unless there is a tie, the Evolution button will indicate which Pokémon it will evolve into. If there is a tie, the tie is broken randomly.
*{{p|Wurmple}} evolves into either {{p|Silcoon}} or {{p|Cascoon}} at random.
*{{p|Clamperl}} evolves into either {{p|Huntail}} or {{p|Gorebyss}} at random.
 
===Pokémon Pinball series===
{{main|Evolution Item (Pinball)}}
In {{g|Pinball}} and {{g|Pinball: Ruby & Sapphire}}, once the Evolution Mode or Evo Mode starts and the player chooses a Pokémon to evolve, then three instances of the same {{OBP|Evolution Item|Pinball}} appear somewhere on the table, one at a time. The player is required to get the three repeated Evolution Items before the time runs up in order to evolve the chosen Pokémon. For instance, if the player attempts to evolve a {{p|Vulpix}} into {{p|Ninetales}}, they will be required to find three [[Fire Stone]]s on the table. Most available Pokémon evolve by [[experience]], which requires getting three "Ex" Evolution Items. If the Pokémon evolves by [[trade]] in the core series, then the player needs to get three [[Game Link Cable|Link Cable]] Evolution Items.
 
==In the TCG==
{{main|Evolution#In the TCG|Evolution → In the TCG}}
 
In the {{pkmn|Trading Card Game}}, there are no different methods needed to evolve a {{TCG|Pokémon}}, but instead, all Pokémon evolve simply by placing an Evolution Pokémon on top of a Pokémon in play that it evolves into. For instance, if the player has a {{TCG|Ekans}} card in play, it evolves when a {{TCG|Arbok}} card is placed on top of it. There are multiple ways for that to occur.
 
Most commonly, Evolution Pokémon can be played from a player's [[hand]] to evolve a Pokémon. This cannot be done to evolve a Pokémon on the first turn of the game or on the same turn a Pokémon enters play. Evolving counts as entering play, so a Pokémon that has evolved or [[Devolution|devolved]] once during a turn cannot be evolved this way a second time.
 
The card {{TCG ID|Base Set|Pokémon Breeder|76}} from {{TCG|Base Set}} allows for a {{TCG|Stage 2 Pokémon}} in the hand to evolve from a {{TCG|Basic Pokémon}} of the same evolutionary line, although only in situations where the Basic Pokémon is allowed to evolve. (Usually, but not always, this means Pokémon Breeder does not work on the first turn of the game or on a Basic Pokémon during the turn it enters play.) This effect essentially skips the {{TCG|Stage 1 Pokémon}} of an evolutionary line and allows for a Stage 2 Pokémon to enter play a turn sooner than otherwise possible.
 
The card {{TCG|Rare Candy}} allows for the process of Evolution from hand to be sped up in some manner. Its effect was changed starting in {{TCG|Dark Explorers}}. Before that set, when played, Rare Candy allows a player to evolve a Basic Pokémon into either a Stage 1 Pokémon in their hand that evolves from that Pokémon, or a Stage 2 Pokémon in their hand of the same evolutionary line. This was allowed to occur even on the first turn of the game or on the same turn a Pokémon enters play. From Dark Explorers onward, an {{TCG|errata}} makes the card act nearly precisely the same way Pokémon Breeder from Base Set does, only allowing a Stage 2 Pokémon from hand to evolve from the Basic Pokémon of that evolutionary line following normal rules about evolving from the hand.
 
Some other {{TCG|Trainer card}}s, like {{TCG ID|XY|Evosoda|116}}, cause a Pokémon to evolve. Usually, they search another zone like the [[deck]] to find a card that evolves from the Pokémon being evolved. Most of these effects cannot evolve a Pokémon on the first turn of the game or on the same turn a Pokémon enters play, as per their own text, but a rare few cards such as {{TCG ID|Evolving Skies|Boost Shake|142}} and {{TCG ID|EX Sandstorm|Wally's Training|89}} are allowed to.

Some {{TCG|attack}}s, {{TCG|Pokémon Power}}s, and {{TCG|Ability|Abilities}} can cause a Pokémon in play to evolve. It does not have to be the Pokémon using the attack, Pokemon Power, or Ability. These effects are usually not restricted by the current turn. Recurring examples of this are the Baby Evolution Poké-Power, the Ascension attack, and the Ultra Evolution attack. These effects usually ignore turn restrictions. Some of them allow for evolving into a Pokémon that does not normally evolve from the Pokémon that is evolving. One example of this is Baby Evolution allowing [[Baby Pokémon]] that are Basic Pokémon to evolve into their evolved forms that are also Basic Pokémon, even though Basic Pokémon do not evolve from any other Pokémon. Another example is that Ultra Evolution, which works like Rare Candy in that it allows a Basic Pokémon to evolve into the Stage 2 Pokémon of its evolutionary line.

Latest revision as of 12:53, 7 September 2024

There are numerous methods of Evolution which define how and when Pokémon evolve. Most Pokémon will evolve by leveling up while others evolve through specific means, such as being traded, achieving a certain amount of friendship or leveling at certain times, among others.

In the core series games

In the core series games, Pokémon normally only evolve after one of three events:

Prior to Generation VIII, the above were the only triggers to evolve Pokémon. However, Pokémon Sword and Shield introduced four new triggers, each only used by a very select few Pokémon species:

  • Spinning and striking a pose with the Pokémon in the party
  • The Pokémon performing a specific action in battle
  • Traveling through a specific location with the Pokémon in the party
  • Observing a specific object in a specific location with the Pokémon in the party

When the appropriate trigger occurs, if the Pokémon meets the requirements to evolve, it will do so. However, if a Pokémon meets the trigger in battle, it will only evolve after the battle ends.

The Everstone prevents a Pokémon's Evolution:

  • In Generation II, a Pokémon holding an Everstone (including Kadabra) cannot evolve by any method.
  • In Generation III, trade Evolutions are affected by the held item loss glitch: if Kadabra, Machoke, Graveler, or Haunter is traded while holding any item (including an Everstone), that Pokémon will evolve and its held item will be permanently lost.
  • From Generation IV onwards, the Everstone does not prevent a Pokémon evolving via Evolution stone. It also fails to prevent Kadabra from evolving.
  • If either Karrablast or Shelmet holds an Everstone when traded for the other, neither can evolve.

Leveling up

Leveling up is the most common trigger for Evolution. Evolution by level up can be triggered by gaining experience in battle or by using a Rare Candy; leveling up in Pokémon Day Care or Isle Evelup will not trigger Evolution, although Pokémon leveled up in these ways can still evolve if leveled up by battle or a Rare Candy afterwards. All Pokémon that evolve by leveling up have at least one requirement that must be met when leveled up in order to evolve, the most common being that the Pokémon must be at least a specific level after leveling up. Other requirements include knowing a specific move, being in a specific location, or holding a specific item. A Pokémon that meets its level-up Evolution requirements will always attempt to evolve when it is leveled up in battle or by using a Rare Candy, regardless of whether it had previously been prevented from evolving.

If a Pokémon levels up in battle, it will not evolve until the battle is over. A Pokémon can only evolve once after a battle or consuming a Rare Candy, even if it gained multiple levels. Even if a Pokémon is fainted at the end of the battle, if it leveled up when it met its Evolution requirements during the battle, it will still evolve, but will not be revived from fainting. However, prior to Generation VI, the player's Pokémon would not evolve if player lost the battle, even if its Evolution requirements were met.

Starting in Generation VIII, if a Rare Candy is used on a level 100 Pokémon that evolves by leveling up and currently meets its Evolution requirements, it will evolve (without gaining a level).

In Pokémon Legends: Arceus, Evolution can be performed at any time as long as the conditions are met, instead of requiring a level up.

At or above a certain level

Main article: Level-based Evolution

Most Pokémon evolve when they reach or surpass a certain level. Once such a Pokémon has reached the required level, unless there are other requirements for its Evolution, it will attempt to evolve after every battle in which it levels up and every time it gains a level from a Rare Candy.

When friendship is high

Main article: Friendship Evolution

Some Pokémon evolve when they are leveled up with a friendship of at least 220. Like friendship itself, this evolutionary requirement was introduced in Generation II. As long as the Pokémon has the required amount of friendship, unless there are other requirements for its Evolution, it will attempt to evolve whenever it levels up by battle or Rare Candy.

Baby Pokémon often have this Evolution requirement, but it is also an Evolution requirement for other Pokémon, and not all baby Pokémon have this as an Evolution requirement.

When the Pokémon knows a certain move

See also: Category:Pokémon that evolve with certain moves

Some Pokémon evolve when they are leveled up and know a certain move or certain type of move. This evolutionary requirement was introduced in Generation IV.

If the Pokémon learns the required move by leveling up, that same level up can trigger the Evolution. However, if a Pokémon learns a move by level up and overwrites the required move, such that it no longer knows the required move at the end of the battle (or after completing the level up in the case of a Rare Candy), it cannot evolve.

These moves are commonly available by leveling up, although some are only learned at level 1, so they normally must be taught by the Move Reminder.

In certain locations

Main article: Location-based Evolution

Some Pokémon evolve when they are leveled up in certain locations. This evolutionary requirement was introduced in Generation IV.

There are four different types of location that can trigger location-based Evolutions: Moss Rock, Ice Rock, special magnetic field, and Mount Lanakila. Mount Lanakila, which is only required for Crabrawler's Evolution, is the only one which is a specific location rather than a type of location.

Pokémon HeartGold and SoulSilver lack the locations needed for location-based Evolutions, making them impossible within those games. Starting in Generation VIII, although some games still feature location-based Evolution and others do not, it is possible to instead use Evolution stones to evolve these Pokémon (except for Nosepass and Eevee's Evolutions into Probopass and Glaceon respectively in Pokémon Brilliant Diamond and Shining Pearl).

In a certain region

Main article: Region-based Evolution

Some Pokémon evolve when they are leveled up in a specific region. This evolutionary requirement was introduced in Generation VII.

Pokémon that evolve this way may also need other conditions, such as requiring it to be a specific time of day. Some Pokémon evolve into different forms depending on what region they are in.

At certain times

Main article: Time-based Evolution

Some Pokémon evolve when they are leveled up at a certain time of day. Like the time mechanic itself, this evolutionary requirement was introduced in Generation II.

The time of day is only ever one of several requirements, never the only one. Other requirements it is combined with include having high friendship or holding a specific held item.

Due to the lack of a time system in Pokémon FireRed and LeafGreen, Pokémon whose Evolution depends on the time cannot evolve.

In Pokémon Sword and Shield, time is pre-set outside the Wild Area before becoming Champion. This also influences Evolution.

While holding an item

See also: Category:Pokémon that evolve by leveling up with a held item

Some Pokémon evolve when they are leveled up while holding a specific Evolution item. If a Pokémon evolves this way, the item disappears upon completion of the Evolution; the item is not consumed if the Evolution is cancelled. This evolutionary requirement was introduced in Generation IV.

All Pokémon that evolve this way also require that they be leveled up at a specific time of day to be evolved.

If the Pokémon is a certain gender

Main article: Gender-based Evolution

The Evolution of some Pokémon that evolve when they are leveled up is dependent on the Pokémon's gender. This evolutionary requirement was introduced in Generation IV.

Combee and Salandit can evolve only if they are female (males cannot evolve). Burmy evolves into either Mothim or Wormadam, depending on whether it is male or female, respectively.

The Evolution of Rockruff and Cosmoem is dependent on the game they are leveled up in. This evolutionary requirement was introduced in Generation VII.

Cosmoem will evolve into either Solgaleo or Lunala depending on the game it is leveled up in. Rockruff will always evolve into Lycanroc, but, prior to Generation VIII, Lycanroc's form depends on the game Rockruff was evolved in, and Rockruff's Evolution can only occur at certain times of day (Midday Form requires it be daytime while Midnight Form requires it be nighttime); furthermore, special Rockruff that have Own Tempo can only evolve into Dusk Form Lycanroc, which is not dependent on the game. Starting in Generation VIII, the form Lycanroc becomes is no longer version-exclusive.

Unique conditions

See also: Category:Pokémon that evolve through a unique method

The following Pokémon evolve through a method that is isolated to their Evolution line only.

Additional factors

Some Pokémon with branched Evolutions can evolve into one of multiple different Pokémon or different forms of the same Pokémon depending on other factors, but still have the same Evolution requirements for all of these possibilities.

  • Burmy evolves starting at level 20, but its evolved form is determined by its gender and, if female, its cloak. As Burmy, its cloak changes according to the place where it last battled but has no effect on Burmy itself; once it evolves into Wormadam, its cloak no longer changes, and its types and the moves it can learn are dependent on its cloak.
    • Male Burmy → Mothim
    • Female Burmy → Wormadam
      • Female Plant Cloak Burmy → Plant Cloak Wormadam (Bug/Grass)
      • Female Sandy Cloak Burmy → Sandy Cloak Wormadam (Bug/Ground)
      • Female Trash Cloak Burmy → Trash Cloak Wormadam (Bug/Steel)
  • Wurmple evolves into Silcoon or Cascoon starting at level 7, depending on its personality value. It is a hidden value determined when the Pokémon is encountered and cannot be seen or affected by the player.
  • Dunsparce evolves into Dudunsparce when leveled up while knowing Hyper Drill. The form of Dudunsparce it evolves into depends on its encryption constant. Since this value cannot be influenced or seen by the player, what a given Dunsparce will evolve into is essentially random — with a 1/100 chance of evolving into Three-Segment Form Dudunsparce.
  • Tandemaus evolves into Maushold starting at level 25, but if Tandemaus is not sent out in the battle it levels up in, the Evolution animation will be skipped. The form of Maushold it evolves into depends on its encryption constant. Since this value cannot be influenced or seen by the player, what a given Tandemaus will evolve into is essentially random — with a 1/100 chance of evolving into Family of Three Maushold.

Using an item

Some Pokémon evolve when they are exposed to a specific item. The player can use one of these items on a compatible Pokémon at any time outside of battle, which consumes the item. From Generation IV onwards, Evolution by exposure to an item cannot be prevented by holding an Everstone. Due to being able to evolve at any time, these Pokémon usually learn fewer or no moves by level up after evolving; however, in Generation VIII, even if they do not learn any additional moves by level-up, they normally can still be taught any move their pre-evolved form could learn by level up by the Move Reminder.

In Pokémon Legends: Arceus only, Pokémon that would normally evolve while holding a particular item (including by leveling up while holding a specific item) instead evolve when exposed to that item.

Evolution stone

See also: Category:Pokémon that evolve by Evolution stone

The most common type of item that can trigger this kind of Evolution is an Evolution stone (and was the only type that could, prior to Generation VIII). Despite its name, the Oval Stone is not an Evolution stone, because it triggers Evolution as a held item rather than by being used directly.

If the Pokémon is a certain gender
Main article: Gender-based Evolution

While most Pokémon that evolve by Evolution stone have no additional requirements, some Pokémon that evolve this way can only evolve if they are a specific gender. This evolutionary requirement was introduced in Generation IV.

The only two Evolutions with this requirement are Kirlia's Evolution into Gallade (which requires that it be male) and Snorunt's Evolution into Froslass (which requires that it be female). These two Evolutions are the only Evolutions to use the Dawn Stone.

Special items

The following items are each only used by one Pokémon to evolve.

Trading

Main article: Trade Evolution

Some Pokémon evolve when they are traded. The Evolution starts immediately after the trade is completed, regardless of the method of trading used. However, sometimes there are additional conditions.

In the animated series, Pokémon that evolve by trade sometimes evolve after being temporarily in a different person's possession, like Misty's Politoed being with Nurse Joy at the Pokémon Center and Brock's Steelix when he lent Onix to his brother Forrest.

See also: Category:Pokémon that evolve by trading with a held item

Some Pokémon evolve when traded while holding a specific Evolution item. If a Pokémon evolves this way, the item disappears upon completion of the Evolution. This method of Evolution was introduced in Generation II (the same generation that introduced held items in general).

In Pokémon Legends: Arceus, Pokémon that evolve when traded while holding a specific item can be evolved without trading by using their Evolution item from the player's satchel.

Unique triggers

Generation VIII introduced several unique triggers for newly introduced Pokémon and regional forms. These triggers are all exclusive to a single Pokémon.

  • Galarian Farfetch'd evolves into Sirfetch'd after it lands three critical hits in a single battle.
  • Galarian Yamask evolves into Runerigus when the player travels through the stone gate in the Dusty Bowl after it has lost 49 HP or more from a single attack and did not faint in the same battle or since.
  • Milcery evolves into Alcremie when the player spins and strikes a pose while Milcery holds a Sweet. Unless Milcery is Shiny, Alcremie's color depends on the time of day, the length of the spin, and the direction of the spin; if Milcery is Shiny, Alcremie takes on its sole Shiny coloration. Alcremie's Sweet corresponds to the Sweet Milcery held. Milcery evolves into:
    • Vanilla Cream Alcremie after spinning clockwise for less than 5 seconds during the day.
    • Ruby Cream Alcremie after spinning counterclockwise for less than 5 seconds during the day.
    • Matcha Cream Alcremie after spinning clockwise for less than 5 seconds at night.
    • Mint Cream Alcremie after spinning counterclockwise for more than 5 seconds at night.
    • Lemon Cream Alcremie after spinning clockwise for more than 5 seconds at night.
    • Salted Cream Alcremie after spinning counterclockwise for less than 5 seconds at night.
    • Ruby Swirl Alcremie after spinning counterclockwise for more than 5 seconds during the day.
    • Caramel Swirl Alcremie after spinning clockwise for more than 5 seconds during the day.
    • Rainbow Swirl Alcremie after spinning counterclockwise for more than 10 seconds during the evening (between 7 and 7:59 PM in real-time in Pokémon Sword and Shield).
  • Kubfu evolves into Urshifu when shown the scroll in one of the Towers of Two Fists. The form it evolves into depends on the tower it is trained in. In Pokémon Scarlet and Violet, Kubfu instead uses a specific Scroll to evolve. Unlike most Evolution items, the Scroll is not consumed after use.
    • Kubfu evolves into Urshifu Single Strike Style when trained in the Tower of Darkness. In Pokémon Scarlet and Violet, Kubfu evolves into Urshifu Single Strike Style when exposed to the Scroll of Darkness.
    • Kubfu evolves into Urshifu Rapid Strike Style when trained in the Tower of Waters. In Pokémon Scarlet and Violet, Kubfu evolves into Urshifu Rapid Strike Style when exposed to the Scroll of Waters.
  • Stantler evolves into Wyrdeer after using Psyshield Bash in the agile style at least 20 times. In Pokémon Scarlet and Violet, Stantler cannot evolve (it is programmed to evolve when leveled up after using Psyshield Bash at least 20 times, but this Evolution method is disabled).
  • White-Striped Basculin evolves into Basculegion after losing at least 294 HP from recoil damage, not counting damage that results in it fainting. In Pokémon Scarlet and Violet, White-Striped Basculin must level up after losing at least 294 HP from recoil damage in order to evolve.
  • Hisuian Qwilfish evolves into Overqwil after using Barb Barrage in the strong style at least 20 times. In Pokémon Scarlet and Violet (starting in Version 3.0.0), Hisuian Qwilfish evolves when leveled up while knowing Barb Barrage.
  • Primeape evolves into Annihilape when leveled up after using Rage Fist at least 20 times.

Can only evolve in other games

Meltan, which first appeared in the core series games in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, cannot be evolved in the core series games. Instead, it can only be evolved in Pokémon GO, where it can be evolved by pressing the "Evolve" button on Meltan's profile screen and spending 400 Meltan Candy.

Pokémon Colosseum and XD: Gale of Darkness

In Pokémon Colosseum and XD, there is no time system:

  • In Colosseum, Pokémon whose Evolution depends on the time cannot evolve.
  • In XD, Evolutions that depend on the time of day instead depend on the Sun Shard and Moon Shard.

Pokémon GO

Main article: List of Pokémon by evolutionary line in Pokémon GO

In Pokémon GO, the only way to evolve Pokémon is to press the "Evolve" button on that Pokémon's profile page. All Pokémon require the player spend a specific amount of their own Candy to evolve them, but some have additional requirements.

Some Evolutions require an item in addition to the Candy cost. All Evolutions that require an Evolution item other than an Evolution stone (except Feebas and Clamperl) or Sun Stone to evolve in the core series require an item to be spent in Pokémon GO. For Evolutions introduced in Generation II, the item required is the same as in the core series. All cross-generational evolutions introduced in Generation IV, except location-based Evolutions, require a Sinnoh Stone to evolve. All Evolutions introduced in Generation V that require an Evolution stone in the core series (except a Sun Stone) require a Unova Stone in Pokémon GO; Generation V Evolutions that require a Sun Stone in the core series also require it in Pokémon GO.

From January 10, 2020 onward, certain Pokémon do not cost any Candy to evolve if they are traded. These Pokémon are Kadabra, Machoke, Graveler, Haunter, Boldore, Gurdurr, Karrablast, Shelmet, Pumpkaboo, and Phantump.

Feebas, Bonsly, Mime Jr., Happiny and Woobat cannot be evolved until the player has walked with them as Buddy Pokémon for a sufficient distance (the specific distance varies between species). This requirement is noted under the "Evolve" button.

For some species of Pokémon with branched Evolutions, there are multiple "Evolve" buttons, allowing the player to choose which Pokémon to evolve into. The different buttons may have different requirements, such as one button requiring an item while another does not.

Despite having branched Evolutions, Eevee, Tyrogue, Wurmple, and Clamperl only have a single button. Some of them have no indication of which Pokémon it will evolve into in most cases.

  • Normally, if the player evolves Eevee, it will randomly evolve into one of Vaporeon, Jolteon, and Flareon. However, if the player meets a special requirement, the player can influence its Evolution.
    • If the player is in range of a Mossy Lure Module or Glacial Lure Module, Eevee will evolve into Glaceon or Leafeon, respectively. In this case, the Evolution button will indicate which Pokémon Eevee will evolve into.
    • Once per nickname, if an Eevee has one of several special nicknames when evolved, it will evolve into a specific Pokémon. If the Eevee is nicknamed "Rainer", "Sparky", "Pyro", "Sakura", "Tamao", "Linnea", "Rea", or "Kira" it will evolve into Vaporeon, Jolteon, Flareon, Espeon, Umbreon, Leafeon, Glaceon, or Sylveon, respectively. Once the player has evolved an Eevee using one of these nicknames, that nickname will no longer have any impact on Eevee's Evolution.
    • If Eevee is currently the Buddy Pokémon and has obtained at least 2 Candy for the player, it will evolve into Espeon during Day Mode or Umbreon during Night Mode.
  • The Pokémon Tyrogue evolves into depends on its highest IV. It will evolve into Hitmonlee if it is Attack, Hitmonchan if it is Defense, or Hitmontop if it is HP. Unless there is a tie, the Evolution button will indicate which Pokémon it will evolve into. If there is a tie, the tie is broken randomly.
  • Wurmple evolves into either Silcoon or Cascoon at random.
  • Clamperl evolves into either Huntail or Gorebyss at random.

Pokémon Pinball series

Main article: Evolution Item (Pinball)

In Pokémon Pinball and Pokémon Pinball: Ruby & Sapphire, once the Evolution Mode or Evo Mode starts and the player chooses a Pokémon to evolve, then three instances of the same Evolution Item appear somewhere on the table, one at a time. The player is required to get the three repeated Evolution Items before the time runs up in order to evolve the chosen Pokémon. For instance, if the player attempts to evolve a Vulpix into Ninetales, they will be required to find three Fire Stones on the table. Most available Pokémon evolve by experience, which requires getting three "Ex" Evolution Items. If the Pokémon evolves by trade in the core series, then the player needs to get three Link Cable Evolution Items.

In the TCG

Main article: Evolution → In the TCG

In the Trading Card Game, there are no different methods needed to evolve a Pokémon, but instead, all Pokémon evolve simply by placing an Evolution Pokémon on top of a Pokémon in play that it evolves into. For instance, if the player has a Ekans card in play, it evolves when a Arbok card is placed on top of it. There are multiple ways for that to occur.

Most commonly, Evolution Pokémon can be played from a player's hand to evolve a Pokémon. This cannot be done to evolve a Pokémon on the first turn of the game or on the same turn a Pokémon enters play. Evolving counts as entering play, so a Pokémon that has evolved or devolved once during a turn cannot be evolved this way a second time.

The card Pokémon Breeder from Base Set allows for a Stage 2 Pokémon in the hand to evolve from a Basic Pokémon of the same evolutionary line, although only in situations where the Basic Pokémon is allowed to evolve. (Usually, but not always, this means Pokémon Breeder does not work on the first turn of the game or on a Basic Pokémon during the turn it enters play.) This effect essentially skips the Stage 1 Pokémon of an evolutionary line and allows for a Stage 2 Pokémon to enter play a turn sooner than otherwise possible.

The card Rare Candy allows for the process of Evolution from hand to be sped up in some manner. Its effect was changed starting in Dark Explorers. Before that set, when played, Rare Candy allows a player to evolve a Basic Pokémon into either a Stage 1 Pokémon in their hand that evolves from that Pokémon, or a Stage 2 Pokémon in their hand of the same evolutionary line. This was allowed to occur even on the first turn of the game or on the same turn a Pokémon enters play. From Dark Explorers onward, an errata makes the card act nearly precisely the same way Pokémon Breeder from Base Set does, only allowing a Stage 2 Pokémon from hand to evolve from the Basic Pokémon of that evolutionary line following normal rules about evolving from the hand.

Some other Trainer cards, like Evosoda, cause a Pokémon to evolve. Usually, they search another zone like the deck to find a card that evolves from the Pokémon being evolved. Most of these effects cannot evolve a Pokémon on the first turn of the game or on the same turn a Pokémon enters play, as per their own text, but a rare few cards such as Boost Shake and Wally's Training are allowed to. (Newer renditions of this effect explicitly say that they can be used on the first turn of the game or on the same turn a Pokémon enters play.)

Some attacks, Pokémon Powers, and Abilities can cause a Pokémon in play to evolve. It does not have to be the Pokémon using the attack, Pokemon Power, or Ability. These effects are usually not restricted by the current turn. Recurring examples of this are the Baby Evolution Poké-Power, the Ascension attack, and the Ultra Evolution attack. These effects usually ignore turn restrictions. Some of them allow for evolving into a Pokémon that does not normally evolve from the Pokémon that is evolving. One example of this is Baby Evolution allowing Baby Pokémon that are Basic Pokémon to evolve into their evolved forms that are also Basic Pokémon, even though Basic Pokémon do not evolve from any other Pokémon. Another example is that Ultra Evolution, which works like Rare Candy in that it allows a Basic Pokémon to evolve into the Stage 2 Pokémon of its evolutionary line.

Some cards reference methods of Evolution found in the core series, such as the Moon Stone, Dusk Stone, Pancham, and Inkay. Not all cards referencing methods of Evolution have an effect which evolves a Pokémon.

In the HeartGold and SoulSilver Series, the art for Pokémon that have evolved in the core series by either using an item, leveling up while holding an item, or being traded while holding an item included their respective Evolution item.[1]

The evolution procedure from the real-life card game is used in Pokémon Trading Card Game, Pokémon Trading Card Game 2: The Invasion of Team GR!, Pokémon Play It!, Pokémon Play It! Version 2, Pokémon Trading Card Game Online, and Pokémon Trading Card Game Live.
