Mega Evolution
- Mega redirects here. For Crystal's Meganium in Pokémon Adventures, which is known as Mega in Chuang Yi translations, see Megaree.
Mega Evolution (Japanese: メガシンカ Mega Evolution) is a transformation affecting Pokémon that was introduced in Generation VI. Mega-Evolved Pokémon are identified by having "Mega" in front of their name.
There are 46 species of Pokémon that are capable of Mega Evolution, and there are 48 different Mega Evolutions.
History
Korrina, the Gym Leader of Shalour City, is said to know secrets about Mega Evolution. The Tower of Mastery is also related to Mega Evolution. According to a Kalos legend, the first Pokémon to have been Mega Evolved was a Lucario. However, according to Zinnia's grandmother in Pokémon Omega Ruby and Alpha Sapphire, Rayquaza was the first Pokémon to Mega Evolve; Mega Evolution was first discovered by the first meeting of humanity and Rayquaza. Professor Sycamore theorizes that Mega Evolution can only be achieved if there is a strong bond between a Trainer and its Pokémon.
In the games
In order to Mega Evolve, most Pokémon must be holding their appropriate Mega Stone and the Trainer must have a Key Stone. Only Rayquaza does not need a Mega Stone to Mega Evolve; instead, it must know the move Dragon Ascent.
In battle
In any battle, each Trainer may Mega Evolve a single Pokémon once. Mega Evolution is essentially a free action a Pokémon may make in addition to its normal move, but if a Pokémon will not use a move, it cannot Mega Evolve. Mega Evolution occurs before most actions except switching. A Mega-Evolved Pokémon will only revert to its original state if it faints or the battle ends; if it is switched out, it will remain Mega Evolved.
A Pokémon cannot Mega Evolve if it is being held in the airborne phase of Sky Drop. Neither volatile nor non-volatile status conditions such as paralysis, sleep, and infatuation will have any effect over a Pokémon's ability to Mega Evolve, even if they result in the Pokémon not being able to move that turn.
Mega Stones are not affected by most moves or Abilities. If they would move a Mega Stone to or from a Pokémon that could use it to Mega Evolve, the moves Bestow, Covet, Fling, Thief, Trick, and Switcheroo will fail and the Abilities Magician, Pickpocket and Symbiosis will not activate. The move Knock Off cannot remove a Mega Stone from a Pokémon that can use it to Mega Evolve, and Knock Off's power will not be increased since it cannot remove the item. The moves Embargo and Magic Room and the Ability Klutz will not prevent a Pokémon from using its respective Mega Stone to Mega Evolve.
Changes in a Pokémon's Ability will take place immediately. A Sharpedo that normally has Speed Boost will not gain a boost in Speed at the end of the turn it Mega Evolves, but if it uses a biting move such as Crunch that turn, it will be boosted by Strong Jaw, its Ability as Mega Sharpedo.
Generation VI
In Generation VI, performing Mega Evolution will not alter the turn order. A Pokémon with a lower Speed than their opponent will still go after them on the one turn the Mega Evolution occurs, even if their Mega Evolution increases Speed and would otherwise cause them to go first. The opposite is also true for Pokémon who lose Speed from Mega Evolution, such as Garchomp. However, turn order will be determined normally on every turn afterwards.
Otherwise, stat changes and type changes due to Mega Evolution take effect immediately and damage calculation proceeds as usual. For example, a Pokémon whose Mega Evolution has a lower base Defense stat takes greater damage from physical moves on the turn it Mega Evolves. Likewise, the move Gyro Ball considers the Pokémon's Speed stat after Mega Evolution for damage calculation, not before.
Likewise, even if a Pokémon only has an Ability such as Prankster before Mega Evolution, appropriate moves will gain priority. If a Pokémon gains Prankster upon Mega Evolution, appropriate moves will not gain priority.
When the player Mega Evolves a Pokémon for the first time since the save file is accessed, a longer animation than usual will play, showing the player activating the Mega Evolution with his or her Mega Bracelet. On subsequent uses of Mega Evolution, a shorter animation will play, showing only the Pokémon as it Mega Evolves.
Generation VII
In Generation VII, a Pokémon's Speed after Mega Evolution is used to determine turn order, not its Speed before. Likewise, if a Pokémon only has an Ability such as Prankster before Mega Evolution, appropriate moves will not gain priority. If a Pokémon gains Prankster upon Mega Evolution, appropriate moves will gain priority.
Rayquaza cannot Mega Evolve if it holds a Z-Crystal.
Outside of battle
In Pokémon Omega Ruby and Alpha Sapphire, Mega Evolution can also occur during the Talent Round of Pokémon Contest Spectaculars. If the participating Pokémon is holding its corresponding Mega Stone when its appeal causes the audience's excitement to reach its peak, it will Mega Evolve and perform a Spectacular Talent. The Pokémon will remain Mega Evolved for the remainder of the Talent Round.
In Pokémon Omega Ruby and Alpha Sapphire, when summoned by the Eon Flute, LatiosOR or LatiasAS will Mega Evolve before the player mounts it to soar in the sky. It will Mega Evolve even if it is not holding its corresponding Mega Stone, since the Eon Pokémon is summoned even if it is no longer in the player's game.
Effects
A Mega-Evolved Pokémon has different base stats, with the exception of HP, and can have a different Ability and type from its non-Mega-Evolved form. Every Mega-Evolved Pokémon (except for Mega Alakazam in Generation VI) has a base stat total 100 points higher than that of its base form.
Pokémon capable of Mega Evolution

Introduced in Omega Ruby and Alpha Sapphire
In other games
Super Smash Bros. for Nintendo 3DS/Wii U
Charizard's, Lucario's, and Mewtwo's Final Smashes Mega Evolve them into Mega Charizard X, Mega Lucario, and Mega Mewtwo Y, respectively. While Lucario and Charizard's Mega Evolutions are used as a temporary power-up, Mewtwo's is used to perform Psystrike.
The Mega Evolutions of Blastoise, Blaziken, Kangaskhan, Venusaur, Lucario, Mewtwo (both forms), and Charizard (X form) appear as trophies in Super Smash Bros. for Wii U, while only Mega Venusaur and Blastoise appear in Super Smash Bros. for Nintendo 3DS.
Description
|
Pokkén Tournament
Lucario, Garchomp, Gardevoir, Gengar, Charizard, Blaziken, Sceptile, Scizor, Blastoise, Mewtwo, and Shadow Mewtwo are able to Mega Evolve through Synergy Burst, with Charizard and both of the Mewtwo Mega Evolving into their X forms. Mega Evolution can be triggered whenever a Pokémon capable of it has its Synergy Gauge filled up to the max during a battle. The Mega-Evolved Pokémon will revert to its regular form once it has used up all of its Synergy power.
In addition, every time when Shadow Mewtwo is fought against in the game's story mode, it will Mega Evolve before the battle begins and stay in this state for the entire fight.
On the Dragon's Nest battle stage, Mega Rayquaza appears in the form of both an enormous statue alongside the battle arena and a drawing on the ground of the battle arena. On the Old Ferrum Town (Winter) battle stage, Mega Swampert appears in the form of a giant snow sculpture. Mega Rayquaza itself is also a Support Pokémon available as part of the Pokkén Tournament DX Battle Pack.
Pokémon Shuffle
Before a Pokémon's Mega Evolution can be used in Pokémon Shuffle, its respective Mega Stone must be obtained (or in Rayquaza's case, the Meteorite), typically either by defeating its Mega-Evolved form in a Trainer battle at the end of each Main Stage Area or as a prize for completing a Competitive Stage or reaching a certain point in an Escalation Battle.
The Pokémon placed in the first position (furthest to the left) when selecting Support Pokémon will Mega Evolve after the player fills the Mega Gauge by matching the Pokémon being Mega Evolved or matching Pokémon with the Mega Boost(+) Skills who are of the same type as the Pokémon being Mega Evolved. The size of the Mega Gauge depends on the Pokémon being Mega Evolved, with each Pokémon requiring different numbers of icons to be matched to fill its gauge. The Mega Effects for each Mega form vary between Pokémon, replacing the Pokémon's Skill for the remainder of the battle.
Pokémon Rumble World
The player gains the ability to Mega Evolve their Pokémon after completing the challenge "Raid of the Mighty General", then receiving the Special Stone Shop and a Mega Key from the rewards section of the ordinary shop. Mega Stones for currently owned Pokémon can be bought and immediately attached to its corresponding Pokémon using the Special Stone Shop. The first Mega Stone of the player's choice is free (unless either the Red or Blue Orb is chosen instead) and every one after it costs 5 Poké Diamonds. During battle, Mega Evolution can performed by tapping the Mega Evolution button using a Pokémon equipped with a Mega Stone in battle. Mega Evolution can be used again on any Pokémon in the same battle, unlike in the main games.
Mega-Evolved Pokémon revert after a completed trip, or when they are defeated or switched out. Mega Evolving will send out a shockwave that damages enemy Pokémon. This shockwave is capable of defeating and tipping over opposing Pokémon.
Pokémon Super Mystery Dungeon
Mega Evolution allows Pokémon to become more powerful, attack multiple enemies, and break down walls. To achieve Mega Evolution, the player must find an Awakening Emera in a Dungeon. These Emeras can be attached to a Looplet of a Pokémon that can Mega Evolve, causing it to Mega Evolve immediately. The Pokémon that Mega Evolves will have their form when moving to the next floor. Should it be given to Mewtwo or Charizard, their Mega Evolution will be chosen randomly. A bar will appear above the Mega-Evolved Pokémon after it transforms and will slowly start to fill up. Once filled, the Mega-Evolved Pokémon will go into Berserk mode. In Berserk mode, the Pokémon will move around and use a powerful attack on any Pokémon surrounding it, friend and foe alike. This will go away after a while, and the Pokémon will revert to normal. When Mega Evolved, its regular attack will get a huge boost in power and range, destroy walls, and reveal purple sparkling spots on the floor which can be picked up for an item.
Attaching an Awakening Emera to a Pokémon that cannot Mega Evolve increases its stats by a lot and give it different boosts. Pokémon that cannot Mega Evolve with an Awakening Emera attached will not go into Berserk mode.
Awakening Emeras are hard to find and appear randomly in dungeons; like other Emeras, they will disappear if they are not reached in time.
Pokémon Picross
Once a player purchases a Mega Pencil from Professor Tetra for 500 Picrites, puzzles for Mega Evolutions can be solved. Furthermore, murals can be solved one tile at a time to display Groudon and Kyogre's Primal Reversions.
Only one Mega Evolution can be set at one time, and they cannot be brought alongside their normal forms. Their skills are higher ranked than their normal counterpart, and they can be used on larger puzzles.
In the TCG
Mega Evolution is featured in the Pokémon Trading Card Game as 
Pokémon
. They were added as a new mechanic to the game in the XY expansion as an evolution of Pokémon-EX cards. Mega Evolving a Pokémon immediately ends a player's turn.
Pokémon tend to have much higher HP and more powerful attacks than regular Pokémon. Currently, all of them have exactly one attack. Uniquely, the artwork of Pokémon feature their attack's name printed in a stylized design on the card as part of the artwork itself. This name is displayed in Japanese, except for Japanese and Korean cards where the name is displayed in English. (Some special Japanese UR variant cards keep the name printed in Japanese instead of English.)
Like all Pokémon, a player who defeats a Pokémon takes two Prize Cards instead of one.

In the Pokémon Adventures manga
Mega Evolution was first presented in the Pokémon Adventures manga in the X & Y arc. At first, it was portrayed as a relatively unknown phenomenon, known only to Gurkinn and his Successors. Since then, it became apparent that Team Flare were also after the power of Mega Evolution, with one member even compiling a list of Mega Stones that they discovered. Simultaneous Mega Evolutions can also be accomplished by a Trainer, as long as they have a Key Stone for each Pokémon they are Mega Evolving. However, doing so will cause severe mental stress on the Trainer, and they will be unable to focus on anything other than a single target until the Mega Evolution is undone.
- When Team Flare members Aliana and Mable arrived in Vaniville Town in order to steal X's Mega Ring, the commotion caused X's baby Kangaskhan, Li'l Kanga, to react with X's Mega Ring and Mega Evolve into Mega Kangaskhan, easily defeating Aliana's Pyroar and Mable's Houndoom.

- The Mega Evolutions of Aerodactyl, Aggron, Ampharos, Mawile and Garchomp made cameos when Gurkinn explained Mega Evolution to Essentia during her raid on the Tower of Mastery. In the subsequent chapter, Gurkinn Mega Evolved his Heracross.
- During Korrina's succession ceremony, three Successors demonstrated Mega Evolution to her by Mega Evolving their Medicham, Scizor and Alakazam respectively.
- While visiting Lumiose City, X met an Electrike, which led him to a Manectite, evolving into Manectric in the process. Later Manectric joins X's team, Mega Evolving into Mega Manectric while facing a Team Flare Grunt.
- During a battle against Team Flare, Gurkinn's Gengar protected X from Celosia's Aegislash. It helped battle against Team Flare to stop them from capturing Xerneas while in tree form. It was later given it to X, at which point he nicknamed it Garma. Garma has a Gengarite, which allows X to Mega Evolve it into Mega Gengar.
- While confronting Essentia, X's Rute and Y's Solsol are given their respective Mega Stones, allowing them to Mega Evolve into Mega Pinsir and Mega Absol respectively.
- Both X's Salamè and Blue's Charizard Mega Evolved into Mega Charizard X and Mega Charizard Y respectively, after defeating Xerosic's Pokémon.
- After reuniting with Blaine, Mewtwo gained the ability to Mega Evolve into both Mega Mewtwo X and Y. Due to their bond, Mewtwo is able to Mega Evolve more than once per battle.
In the Omega Ruby & Alpha Sapphire arc, the role of Mega Evolution was diminished but its accessibility continued to be confined to a selected number of Trainers.
- In Omega Alpha Adventure 1, Ruby, Sapphire, and Emerald were shown learning how to Mega Evolve their Pokémon from Ultima. Sapphire and Emerald were seen mastering it in Omega Alpha Adventure 3, where they Mega Evolved their respective starter Pokémon.
- In Omega Alpha Adventure 2, Ruby was able to successfully Mega Evolve Latios into Mega Latios, allowing them to soar into the sky. He soon arrived at the Sky Pillar, where he met and battled Zinnia, who used her Mega Salamence against Mega Latios.
- In Omega Alpha Adventure 6, Steven Mega Evolved his Metagross into Mega Metagross with his Mega Stickpin.

In retaliation, Red and Green Mega Evolved Saur and Blasty into Mega Venusaur and Mega Blastoise respectively to battle them.
- In Omega Alpha Adventure 15, footage of Rayquaza Mega Evolving was seen.
- In Omega Alpha Adventure 20, Giovanni Mega Evolved his Beedrill as part of his explanation that the meteoroid headed for Hoenn may be housing a Pokémon inside of it, since Mega Evolution is only supposed to work within a battle. Later, Sapphire and Ruby Mega Evolved Kirly and Rara into Mega Gallade and Mega Gardevoir respectively during a brief battle against each other.
- In Omega Alpha Adventure 21, Ruby and Sapphire Mega Evolved Rayquaza in order to have it destroy Grand Meteor Delta. Later in the Pokémon Contest Spectacular, Ruby is able to Mega Evolve Diancie for his and Sapphire's performance.

Trivia
- Every type has at least one Mega Evolution: Psychic has the most (with ten), while Ice and Electric have the fewest (with two each).
- Electric is the only type for which no new Mega Evolution was introduced in Pokémon Omega Ruby and Alpha Sapphire.
- Gardevoir and Gallade are the only Pokémon capable of Mega Evolution that are in the same evolutionary family.
- Only Pokémon which cannot evolve further are capable of Mega Evolution.
- Aerodactyl is the only Fossil Pokémon capable of Mega Evolution.
- Rayquaza is the only trio master capable of Mega Evolution.
- Diancie is the only Mythical Pokémon capable of Mega Evolution.
- With base stat totals of 780, Mega Mewtwo X, Mega Mewtwo Y, and Mega Rayquaza have the highest base stat totals of any Pokémon.
- In addition, Mega Mewtwo Y has the highest base Special Attack of all Pokémon at 194, and Mega Mewtwo X has the highest base Attack of all Pokémon at 190. Mega Mewtwo X also has the highest base stat increase of all Mega Evolutions, its Attack stat being boosted by 80 upon the process.
- Aggron is the only dual-type Pokémon to become single-type upon Mega Evolving, going from Steel/Rock-type to pure Steel-type.
- The only Pokémon with multiple Mega Evolutions are Charizard and Mewtwo, which each have two. In both cases, the first ones to be revealed were the Y versions.
- In addition, both of their Y Mega Evolutions kept their original type, while both of their X Mega Evolutions changed their type.
- Also, in both cases, the X Mega Evolution is more physically-oriented (with a higher Attack and/or Defense), while the Y Mega Evolution is more specially-oriented (with a higher Special Attack and/or Special Defense).
- Rayquaza is the only Pokémon that does not require a Mega Stone to Mega Evolve in the core series games, instead being required to know Dragon Ascent.
- This makes Rayquaza the only Pokémon that can have a different held item while Mega Evolved, since Mega Stones cannot be taken off their proper holder during battle.
- In Pokémon Shuffle Rayquaza needs the player to get the Meteorite for it to Mega Evolve.
- Mega Latias and Mega Latios are programmed into Pokémon X and Y; as a result, they are not banned by the Kalos rules from battles, and their Mega Stones are not banned from trades between Omega Ruby or Alpha Sapphire and X or Y, despite being otherwise unavailable in those games.
- The Japanese and Korean logos for Pokémon X and Y include the Mega Evolution sigil.
- In an interview with the Nintendo Dream magazine, Ken Sugimori stated that Flygon was intended to get a Mega Evolution in Pokémon X and Y, but the idea was dropped due to him experiencing artist's block.
- In the Pokémon X and Y demo, the message "An immense rare power has risen in Mewtwo" would be displayed before Mega Evolving. In the final game, the message displayed is "<Pokémon>'s <Mega Stone> is reacting to <Trainer>'s <Key Stone item>!" Additionally, Mega Mewtwo Y is referred to as simply Mega Mewtwo.
