Blaziken Mega Evolving into Mega Blaziken
Mega Evolution (Japanese: メガシンカ Mega Evolution) is a temporary transformation introduced in Pokémon X and Y that affects certain Pokémon. It is present in the Generations VI and VII core series games, and is set to reappear in Pokémon Legends: Z-A. In its core series absence, it has remained usable in multiple spin-off games, such as GO, Masters EX, and UNITE.
There are currently 46 species of Pokémon that are capable of Mega Evolution, and there are currently 48 different Mega Evolutions.
Terminology
Mega Evolution is described as a phenomenon[1] as well as the transformed Pokémon. The related verb is Mega Evolve.
The Mega Evolved Pokémon are identified by having "Mega" in front of their name, such as Mega Altaria or Mega Ampharos. In the case of Charizard and Mewtwo, each of them has two Mega Evolutions with either the letter X or Y after the species name: Mega Charizard X, Mega Charizard Y, Mega Mewtwo X, and Mega Mewtwo Y. However, X and Y's demo called Mega Mewtwo Y simply "Mega Mewtwo."

History
The history and origins of Mega Evolution are shrouded in mystery and apparent contradictions, with different characters and groups having their own beliefs on where the phenomenon originated. For instance, Professor Sycamore theorizes Mega Evolution originates from special stones, possibly Evolution stones, that were irradiated by the light of XerneasX/YveltalY that was fired from the ultimate weapon 3,000 years ago. Despite this, Sycamore additionally claims that Mega Evolution is a new type of Evolution, and that the phenomenon only occurs in the Kalos region.[2] Additionally, Sina, Sycamore's assistant who is in Alola on his behalf, makes claim that it is mysterious to be talking about Mega Evolution so far away from Kalos.[3]
However, the Draconid people, an ancient tribe from the Hoenn region that worship Rayquaza, believe that Mega Evolution originates from Rayquaza and various meteorites that rained down upon the Hoenn region thousands of years ago.
According to knowledge passed down by the Draconids, during the long-lost primal age of Hoenn, one of the many disasters that struck the region were numerous meteorites that rained from space and landed in the home of the Draconids, Meteor Falls, with these meteorites glowing a rainbow brilliance, not unlike the description of a Key Stone, which attracted Rayquaza and led to it putting an end to the disasters and restoring peace.
One thousand years later, disasters befell the region once more, most notable was a massive meteorite described with boundless brilliance and directly compared to a Key Stone, that bore deep into the ocean and created what would eventually come to be the location of Sootopolis City; with the impact cracking the ground and releasing a wave of primal energy, causing Groudon and Kyogre to awaken once more in their thirst for this power. This led the people to wish for Rayquaza to appear once more and save them, as it had done in the past, and once Rayquaza did appear, the people fell to their knees and wished for salvation, causing a great change to overtake Rayquaza as it Mega Evolved, with it using this power to defeat Groudon and Kyogre once again.
While the knowledge of the Draconids implies Rayquaza was the first Pokémon to Mega Evolve, an old Kalos legend from the Tower of Mastery tells of a Trainer and Lucario arriving in the region long ago, with the pair discovering two strange stones and subsequently leading to the world's first Mega Evolution.
The usage of Mega Evolution unleashes a massive amount of energy, as mentioned by Professor Cozmo, which itself is implied to have a direct connection, if not outright be a Pokémon's own life force, as it's mentioned by Lysandre that Professor Sycamore believes Mega Evolution releases all of a Pokémon's hidden energy at once that can't be achieved via regular evolution; this is coupled with CourtneyOR/Matt'sAS attempt at causing a rocket filled with Infinity Energy to explode, with Matt outright claiming it'd be like Mega Evolving the rocket.
While Steven Stone claims what exactly Mega and Key Stones are is a mystery, Archie, Maxie, and the events of the Delta Episode show that meteorites contain their own latent power and under the right conditions can be turned into either Mega or Key Stones. This is directly demonstrated in Omega Ruby and Alpha Sapphire, where the Meteorite slowly changes to resemble a Mega Stone over the course of the game, before it's eventually consumed by Rayquaza during the Delta Episode. While this allows the Legendary Pokémon to Mega Evolve without technically holding the stone, it's implied by Zinnia that Mega Stones, or at least the meteorites that fuel Rayquaza's Mega Evolution, eventually lose their power.
Similarly to Mega Stones, Key Stones can also be found in certain locations, such as Meteor Falls, where Matt found his.
In Pokémon Ultra Sun and Ultra Moon, Colress questions whether or not Z-Power can surpass the Mega Ring.[4] Dexio and Sina directly imply that the two are similar due to the Trainer-Pokémon relational bond.[5]
In battle
In the core series games, Mega Evolution requires the player to hold a Key Stone and a Pokémon capable of Mega Evolution holding its compatible Mega Stone. Only Rayquaza does not need a Mega Stone to Mega Evolve; instead, it must know the move Dragon Ascent. In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, the player simply needs to have the required Mega Stone in their bag, since there is no held item feature. Although some most media describes that a strong bond with the Pokémon and their trainer is needed, neither Friendship or Affection is necessary to Mega Evolve in the games.
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
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.
A transformed Pokémon (either by Transform or Imposter) is unable to Mega Evolve. It will fail to Mega Evolve even if it is transformed into the correct species and it is holding the respective Mega Stone. However, it is possible to transform into a Mega-Evolved Pokémon by copying another Mega-Evolved Pokémon. The restriction of only one Mega Evolution per battle does not apply to transformed Pokémon.
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.
In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, as the Held item mechanic is not implemented, the player simply needs to have the compatible Mega Stone in their bag to access a Pokémon's Mega Evolution. The player can also manually pick which form Charizard or Mewtwo can become from the move menu.
Generation IX
Mega Evolution is set to return in Pokémon Legends: Z-A, after six years of absence.
Outside of battle
A
Gardevoir Mega Evolving in a Contest Spectacular
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.
In the spin-off games
- Main article: Mega Evolution (GO)
Mega Evolution was introduced in Pokémon GO on August 27, 2020. Rather than using a Mega Stone, an eligible Pokémon instead consumes Mega Energy to undergo a temporary Mega Evolution.
- Main article: Mega Evolution (Masters)
Certain sync pairs can Mega Evolve their Pokémon by performing a sync move in Pokémon Masters EX since the game's launch.
- Main article: Mewtwo (Unite License X)
- Main article: Mewtwo (Unite License Y)
Mewtwo can become Mega Mewtwo X or Mega Mewtwo Y. This is facilitated by its Pressure Ability, which has a Mega gauge which is filled by using basic attacks and moves. Unlike in the core series, Mewtwo can only be Mega Evolved for a set amount of time, delineated by the Mega gauge draining back to empty, after which it returns to being a normal Mewtwo. However, Mewtwo can refill its Mega gauge to Mega Evolve multiple times in the same battle. When Mega Evolved, Mega Mewtwo X and Mega Mewtwo Y have different basic attacks and increased stats compared to Mewtwo.
There are two Unite Licenses for Mewtwo. While both of them allow for using Mewtwo, each one has separate characteristics. Only the Unite License X one Mega Evolves into Mega Mewtwo X, while the Unite License Y one allows for Mega Evolving into Mega Mewtwo Y.

Super Smash Bros. series
Charizard and Lucario's Final Smashes are both Mega Evolution, which transforms them into Mega Charizard X and Mega Lucario, respectively. This Mega Evolution acts as a temporary power-up for the duration of the Final Smash.
Mewtwo's Final Smash is Psystrike, which has it Mega Evolve into Mega Mewtwo Y then use Psystrike.
Mega Venusaur and Mega Blastoise appear as trophies in Super Smash Bros. for Nintendo 3DS. Mega Blastoise, Mega Blaziken, Mega Kangaskhan, Mega Venusaur, Mega Lucario, Mega Mewtwo X, Mega Mewtwo Y, and Mega Charizard X appear as trophies in Super Smash Bros. for Wii U.
Description
Mewtwo retains its Final Smash Psystrike from Super Smash Bros. for Nintendo 3DS/Wii U, which still causes it to Mega Evolve into Mega Mewtwo Y.
Lucario's Final Smash, Aura Storm, has it Mega Evolve into Mega Lucario in order to use it.
Mega Charizard X, Mega Kangaskhan, Mega Mewtwo Y, Mega Lucario, and Mega Diancie appear as Spirits.
- Main article: Mega Evolution (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). Methods to obtain a Mega Stone include:
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. This is filled by matching the Pokémon being Mega Evolved, or by 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 maximum amount of icons needed to fill the gauge can be permanently decreased by using 
Mega Speedup Enhancements, with each Pokémon having a different maximum amount of Mega Speedups they can take.
Once a Pokémon is Mega Evolved, its skill is replaced by its Mega Effect for the remainder of the battle. Mega Effect varies between Pokémon.
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 be 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. Additionally, it also resets any negative status conditions or status changes the Pokémon had before Mega Evolving.

Mega Evolution in Pokémon Super Mystery Dungeon
Mega Alakazam in Berserk mode
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. A Looplet attached with an Awakening emera will have a rainbow glow 
. 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. As long as the bar is present, the Mega-Evolved Pokémon will keep their form even when moving to the next floor. Once the bar is 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.
Mega Evolution returns in Pokémon Mystery Dungeon: Rescue Team DX, and in this game is achieved by eating an Empowerment Seed. Mega Evolved Pokémon also have all of the bonuses granted by the Awakened status: linked moves always result in critical hits, moves will never miss, and moves will ignore unfavorable type matchups. Compared to the Awakened status, the only additional bonus Mega Evolution grants is the potential to change a Pokémon's type and ability.
As in Pokémon Super Mystery Dungeon, if Mewtwo or Charizard Mega Evolves, their Mega Evolution will be chosen randomly.
Some bosses will also undergo Mega Evolution or Primal Reversion:
- During Rayquaza's rematch or Mewtwo's boss fight, both will Mega Evolve once their health drops below one half of their total. Mewtwo will Mega Evolve randomly into Mega Mewtwo X or Mega Mewtwo Y.
- Similarly, Groudon (during its rematch) and Kyogre (during its boss fight) will undergo Primal Reversion once below half of their total health.
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 (however, murals do not require the Mega Pencil).
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.
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.
In animation
Pokémon the Series
Multiple Mega Evolutions have been featured in Pokémon the Series.
- The first Mega Evolution in the anime was featured in Mewtwo — Prologue to Awakening, where Mewtwo was shown to be capable of changing between its regular form and Mega Mewtwo Y, in which its speed was dramatically boosted, being capable of moving faster than the blink of an eye. The same Mewtwo also played a major role in Genesect and the Legend Awakened, once again demonstrating its Mega Evolution capabilities. Unlike in the games, this Mewtwo seemed to be capable of Mega Evolving without the use of a Mega Stone. However, because the concept of Mega Evolution had not been announced at the time of the movie's release, this transformation remains unnamed in the movie. Some Japanese promotional material for the movie as well as its manga adaptation referred to it as Mewtwo's Awakened Form (覚醒した姿).[6]
- The first Mega Evolution in the main series was featured in Kalos, Where Dreams and Adventures Begin!, where Ash saw a Mega Blaziken. In the next episode, it was revealed to belong to a masked hero called the Blaziken Mask, saving Ash from a free fall from the Prism Tower. It has since been seen helping Ash and his friends on numerous occasions.
- A Mega Ampharos and a Mega Charizard X appeared as silhouettes in Lumiose City Pursuit! while Professor Sycamore told Ash, Clemont, and Bonnie about the concept of Mega Evolution.
- In Mega Evolution Special I, a Trainer named Alain was featured traveling across the Kalos region with his Mega Charizard X, challenging other Mega Evolution Trainers. During the episode, Alain battled Astrid's Mega Absol and Remo's Mega Garchomp, and was victorious in both battles. Later in the special, he even faced the Elite Four member Siebold and his Mega Blastoise, but the powerful Water-type Pokémon proved to be too much for Charizard, causing Alain to lose the battle.
- All known Mega Evolutions released at the time were also featured during the intro of the aforementioned special episode.
- Diantha's Mega Gardevoir first appeared in The Bonds of Evolution!, using its Mega Evolution powers to break free from Team Rocket's binds.
- Korrina has a Lucario that can Mega Evolve, and so does her grandfather Gurkinn, as shown in The Aura Storm!. In Origins of Mega Evolution!, it was shown in a flashback how one of Gurkinn's ancestors discovered a Key Stone, while his Lucario discovered a Lucarionite, leading to the first known Mega Evolution.
- In Calling from Beyond the Aura!, Korrina told Ash and his friends about a Trainer she had once met who had used a Mega Ampharos.
- A Trainer named Mabel and her Mega Mawile appeared in The Bonds of Mega Evolution!.
- Diancie Mega Evolved in Diancie and the Cocoon of Destruction in order to protect the Allearth Forest from Yveltal and restore the Diamond Domain by creating a new Heart Diamond. At the end of the movie, it was shown that a diamond Diancie had created and given to Bonnie earlier caused it to Mega Evolve, acting as a Key Stone.
- During the intro of Diancie and the Cocoon of Destruction, Wikstrom is seen Mega Evolving his Scizor in a battle against Diantha and her Mega Gardevoir.
- Steven Stone's Shiny Mega Metagross appeared in Mega Evolution Special II, as well as Mega Rayquaza. Both reappeared in Mega Evolution Special III.

- The Latios, Latias, and Shiny Rayquaza that Hoopa summoned in Hoopa and the Clash of Ages all Mega Evolved during the movie. Much like the Mewtwo from the sixteenth movie, they were able to Mega Evolve without a Key Stone or their respective Mega Stones.
- In Mega Evolution Special IV, Alain battled ten Mega-Evolved Pokémon and their Trainers in a row, including Mega Venusaur, Mega Alakazam, Mega Heracross, Mega Scizor, Mega Ampharos, Mega Aggron, and Mega Pinsir. The final Trainer of the row was the Elite Four member Malva, who used a Mega Houndoom. At the end of the episode, Alain was also seen battling a Trainer with a Mega Banette.
- A Mega Audino appeared in A Giga Battle with Mega Results!, under the ownership of a Nurse Joy.
- In A Real Icebreaker!, Wulfric Mega Evolved his Abomasnow into Mega Abomasnow to fight against Ash's Greninja during their Gym battle.
- A Mega Alakazam, Mega Glalie, Mega Pidgeot, Mega Steelix, Shiny Mega Gengar, Shiny Mega Gardevoir, and several other Mega-Evolved Pokémon appeared in Volcanion and the Mechanical Marvel. With the exception of Kimia's Shiny Mega Gardevoir, they were forcibly Mega Evolved by a special device known as Mega Wave, which was being used by Alva and his minions Levi and Cherie. A Mega Wave evolved Mega Heracross and Mega Pinsir were also loaned to Team Rocket.

Pokémon Adventures
At first, Mega Evolution 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.

- In PS611, footage of Rayquaza Mega Evolving was seen.
- In PS616, 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.

Pokémon Journeys: The Series
During a flashback in Toughing It Out!, it was revealed that Ash fought Korrina's Mega Lucario in a World Coronation Series battle.
In the TCG
Mega Evolution is mainly featured in the Pokémon Trading Card Game as Mega Evolution Pokémon. Their names have 
as a prefix and 
as a suffix. They additionally have a distinct stage of "MEGA". Naturally, these are also Pokémon-EX They were added as a new mechanic to the game in the XY set as an evolution of Pokémon-EX cards. Mega Evolving a Pokémon immediately ends a player's turn, unless that Pokémon has its specific Spirit Link Pokémon Tool attached to it.
Atsushi Nagashima, the game director for the TCG, has stated that Mega Evolution is exclusive to Pokémon-EX because it would be impractical to evolve a single Pokémon three times during a game, and implementing Mega Evolution in that manner would constrain deck-building.[7] The team had considered restricting players to one Mega-Evolved Pokémon per deck, but rejected this idea, as they wanted to enable players to build decks based around Mega Evolution.[8]
In Unified Minds and Cosmic Eclipse, two TAG TEAM Pokémon-GX were printed that feature Mega Evolved Pokémon as one of the two members of the tag team. These cards have no special mechanics outside of those which are part of the TAG TEAM mechanics.
The following is a list of cards mentioning or featuring Mega Evolved Pokémon in the Trading Card Game.
Trivia
- According to Ken Sugimori in his interview in the Nintendo Dream magazine, Flygon was intended to get a Mega Evolution in Pokémon X and Y, but the idea was later dropped due to him experiencing an artist's block.[9]
- There is at least one Mega Evolved Pokémon of every type: Psychic has the most (with ten), while both Ice and Electric have the fewest (with two each).
- 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.
- No Mega Evolved Pokémon receives an increase to its HP stat.
- Mega Aggron and Mega Steelix are tied with Shuckle as having the highest base Defense stat of all Pokémon, at 230.
- Mega Latias has the highest base Special Defense stat of any Mega, at 150.
- Mega Alakazam and Mega Aerodactyl are tied as having the highest base Speed stat of any Mega, at 150.
- With base stat totals of 780, Mega Mewtwo X, Mega Mewtwo Y, and Mega Rayquaza have the highest base stat totals of any obtainable Pokémon. Eternamax Eternatus has the highest base stat total of all Pokémon at 1125, but cannot be used by the player.
- 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.
- Sableye and Mawile have the lowest base stats totals of any Pokémon capable of Mega Evolution, at 380.
- Several Mega Evolution Pokémon reduce some of their base stats to increase others, those being:
- 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 have two each and were introduced in Generation I. 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(s), while both of their X Mega Evolutions changed or added their secondary 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.
- It is, furthermore, the only Pokémon to lack the message "(The opposing) <Pokémon>'s <Mega Stone> is reacting to its Key Stone!" when it Mega Evolves, as it has the message "<player>'s fervent wish has reached Rayquaza!" instead.
- In Pokémon Shuffle, Rayquaza needs the player to get the Meteorite for it to Mega Evolve.
- Although Rayquaza can learn Dragon Ascent in Generation VIII onward, it cannot Mega Evolve in those games.
- 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 the Pokémon X and Y demo, the message "An immense new 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.
- Mega Altaria is the only Mega Evolved Pokémon with a unique type combination.
- Mega Kangaskhan and Mega Rayquaza are the only Mega Pokémon which have a signature Ability.
- If not counting movies or the Mega Evolution Specials, overall twenty-two Mega Evolutions haven't appeared in the main anime.
- No Pokémon capable of Mega Evolution has an exclusive Z-Move.
- Due to Mega Evolution being absent from Generation VIII onward, this have affected the status of some Abilities:
- Slowbro is the only Pokémon to have both a Mega Evolution and a regional form.
- The fully-evolved Kanto first partner Pokémon and Gengar are the only Pokémon that can both Mega Evolve and Gigantamax.
- In contrast to the other Paradox Pokémon, Roaring Moon and Iron Valiant bear resemblance to Mega Evolved forms of the Pokémon they are based on rather than the basic form.
- The Pokédex description for Roaring Moon in Pokémon Violet makes a reference to Mega Evolution.
- The lore behind Mega Evolutions remains inconsistent in how it affects the Pokémon who undergo it. In X and Y, it was stated to be the bond between a trainer and Pokémon, and no ill effects are implied. In Sun and Moon and Ultra Sun and Ultra Moon, the Pokédex makes it clear that Mega Evolution is harmful; however, in Let's Go Pikachu and Let's Go Eevee, the Pokédex goes back to the bond with a trainer and harmless entries.

Notes
- ↑ 1.0 1.1 Mega evolutions of Latias and Latios were officially added in Pokémon Omega Ruby and Alpha Sapphire, but they were already programmed into Pokémon X and Y and as such players could trade their Mega Stones and use them in those games.
