===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 / 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.Professor Sycamore:"It's only a hypothesis, but I think the bond between Pokémon and Trainer is the key to this new Evolution. But what is this bond, exactly? And why are there examples of Mega Evolution only in the Kalos region? There's still so much we don't know..." (Pokémon X and Y) 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.Sina: "It's so mysterious... to be talking about Mega Evolution here, in a region so far away from Kalos..." (Pokémon Sun and Moon).Mega Evolution is referred to as Evolution beyond Evolution.| Mega Evolution (Archived) Mega Evolution is said to be an Evolution that surpasses a Pokémon's limit. It is known to be one of the Kalos region's greatest mysteries. 
However, the Draconid people, an ancient tribe from the Hoenn region that worship , 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 and 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 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 Courtney/Matt's 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 , 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.Colress: "Z-Power... Is it the true potential that I seek? Does it surpass the Mega Ring?" (Ultra Sun and Ultra Moon) Dexio and Sina directly imply that the two are similar due to the Trainer-Pokémon relational bond.Sina: "You know, when you think about it, the Z-Power Ring helps the feelings of a reach their Pokémon so it can use its Z-Move, right? It only follows that it should be able to achieve Mega Evolution, too!" (Ultra Sun and Ultra Moon)
===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 does not need a Mega Stone to Mega Evolve; instead, it must know the move . 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 , 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 . 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 , , , , , and will fail and the Abilities , and will not activate. The move 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 and and the Ability 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 that normally has 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 that turn, it will be boosted by , its Ability as Mega Sharpedo.
A transformed Pokémon (either by or ) 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 the turn the Pokémon undergoes Mega Evolution. 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 . 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 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 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 their 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 before Mega Evolution, appropriate moves will not gain priority. If a Pokémon gains Prankster upon Mega Evolution, appropriate moves will gain priority.
 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===
In Pokémon Omega Ruby and Alpha Sapphire, Mega Evolution can also occur during the 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 . 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, or 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==
===Pokémon 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 Mega Evolution for 8 real life hours.
===Pokémon Masters EX===
Certain sync pairs can Mega Evolve their Pokémon by performing a sync move in Pokémon Masters EX since the game's launch.
===Pokémon UNITE===
 can become Mega Mewtwo X or Mega Mewtwo Y. This is facilitated by its Ability, which has a Mega gauge which is filled by using basic attacks and s on members of the opposing team. If the gauge is full, and Mewtwo is at least Level 5, it will Mega Evolve.
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.
Starting from version 1.14.1.2, Mewtwo spends some of the Aeos energy it is holding when it Mega Evolves. The Mega Evolution will last longer if Mewtwo uses up more Aeos energy.
There are two Unite Licenses for Mewtwo. While both of them allow for using Mewtwo in a Unite Battle, each one has separate characteristics. Only the Unite License X one Mega Evolves into Mega Mewtwo X, while the Unite License Y one Mega Evolves into Mega Mewtwo Y.

===Pokémon Shuffle===
Before a Pokémon's Mega Evolution can be used in Pokémon Shuffle, its respective Mega Stone must be obtained (or in 's case, the Meteorite). Methods to obtain a Mega Stone include:
* Defeating a Pokémon's Mega-Evolved form in a battle, usually at the end of each .
* Completing certain objectives on Mission Cards.
* Reaching certain s by catching several different species of Pokémon.
* Achieving a high rank in a competitive stage.
* Clearing certain milestone stages in an escalation battle.
The Pokémon placed in the first position (furthest to the left) when selecting 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 (, ) s 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 , 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.
===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 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.
===Pokémon Mystery Dungeon series===
====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. A Looplet attached with an Awakening emera will have a rainbow glow . Should it be given to or , 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 . 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 Mystery Dungeon: Rescue Team DX====
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 or Mega Evolves, their Mega Evolution will be chosen randomly.
Some bosses will also undergo Mega Evolution or Primal Reversion: 
* During '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, (during its rematch) and (during its boss fight) will undergo Primal Reversion once below half of their total health.
===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 and '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.
===Pokkén Tournament===
, , , , , , , , , , 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 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 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.
