Mega Evolution

Mega Mewtwo Y vs. Mega Lucario.

Pidgeot Mega Evolving into Mega Pidgeot

Mega Evolution (メガ進化(しんか) Mega Shinka) is a concept introduced in Generation VI. It consists of certain Pokémon gaining an ultimate form of themselves. The Pokémon need special Mega Stones in order to evolve into their final form for one-evolution/branch evolution families and ultimate forms for two-evolution families. Also, Pokémon can only gain their ultimate form by using a Mega Stone unique to their species. For example, to evolve Blaziken into Mega Blaziken, Blaziken must be holding the Mega Stone, Blazikenite.

Mega Evolution does more than just change a Pokémon's appearance: it also changes their types, ability and stats. An example is Ampharos, which, after Mega Evolution, becomes an Electric/Dragon-type Pokémon. But some Pokémon, like Aggron, lose a type after Mega Evolution, going from a Steel/Rock-type Pokémon to a just pure Steel-type Pokémon.

Mega Evolution is only possible during a battle or contest. After the battle/contest ends, the Pokémon will revert into their normal forms. Thus, it is a Temporary Evolution. You are limited to having only one Mega Evolution in a battle. Each individual Mega Stone can be used an infinite number of times, but only once per battle.

The Mega Evolutions are, in fact, their own species of Pokémon, as seen by the statement that accompanied Mega Mewtwo Y's original reveal which called it "a new Pokémon related to Mewtwo" and also Red stating in Pokémon Origins that Charizard has "evolved even further!"

In Pokémon Ultra Sun and Ultra Moon, it is revealed that Mega Evolution is a very dangerous form of evolution and that it is painful to the Pokémon undergoing through that Evolution.

Anime

Main article: Pokémon: Mega Evolution Special I, and Pokémon: Mega Evolution Special II, and Pokémon: Mega Evolution Special III

In the special Mewtwo — Prologue to Awakening and the movie Genesect and the Legend Awakened, a Mewtwo appeared that has the power to mega evolve into its Mega Mewtwo Y form. At that time, that was Mewtwo's "Awakened" Form.

In the regular anime, in the first episode of the XY series, Kalos, Where Dreams and Adventures Begin!, a Mega Blaziken appeared, belonging to an unknown Trainer. It appeared again in Mega-Mega Meowth Madness!, and it was revealed that its Trainer is Meyer, the father of Clemont and Bonnie.

In the anime special, Pokémon Origins, in File 2 - Cubone, two strange stones are given to Red, not knowing what they were. In File 4 - Charizard, while trying to catch a Mewtwo, he discovered that the stones were a Key Stone and a Charizardite X, allowing his Charizard to Mega Evolve into Mega Charizard X, making him capable of catching Mewtwo.

The special Mega Evolution Special I is especially focused in Mega Evolution. First, we see a Mega Abomasnow battling a Mega Gyarados in the rain. After that, an introduction of all Mega Evolutions known at the time is given. The special is about Alain, who wants to discover the secret of Mega Evolution, battling each Trainer that can make their Pokémon Mega Evolve. First, he is battling Astrid with her Mega Absol. After an intense battle, he wins. Following, he goes and finds an Aerodactylite, and a character named Remo challenges him to a battle with his Mega Garchomp nicknamed "Garchoo" to reclaim the Mega Stone. Alain wins again with his Mega Charizard X, and following he challenges the Elite Four member Siebold. In the battle, Siebold uses his Mega Blastoise and wins.

Back to the regular anime, in the episode The Bonds of Evolution!, Ash and friends meet the Kalos Champion, Diantha, and they see her battle another Trainer using her Gardevoir with the capacity of Mega Evolving.

In the episode Mega Revelations!, Ash and friends meet Korrina and her Lucario, she explains that they're traveling to dominate Mega Evolution and then she joins them to travel. In the next episode, The Cave of Trials!, they meet Gurkinn, Korrina's grandfather. Both of them have a battle, using her Lucario and his Blaziken, respectively. The episode ends in Korrina's Lucario Mega Evolving. Unfortunately, in The Aura Storm!, when Lucario finally Mega Evolves, loses control of itself. Gurkinn then leaves them and tells her to train with her Mega Lucario. In the episode Calling from Beyond the Aura!, Korrina and Lucario train to dominate that Mega Lucario form, with no luck, Mega Lucario loses control once again. In the following episode, The Bonds of Mega Evolution!, Korrina meets Mabel and her Mawile. In that same episode, Korrina and Maple have a battle, Korrina Mega Evolves her Lucario, while Mabel her Mawile. During the battle, Mega Lucario loses again control, letting Mega Mawile win. In this episode, Korrina leaves the group.

The special Mega Evolution Special II continued with the story of Alain. The episode featured Mega Sceptile, Mega Swampert, Mega Blaziken, and Mega Metagross along with Steven Stone. Alain would eventually transition into the main anime, forming a rivalry with Ash and his special Greninja.

Trivia

• Mew and Ditto can both take on the form of a Mega Evolution, but cannot Mega Evolve themselves.
• Mewtwo and Charizard are the only Pokémon to have two Mega Evolutions. The different evolutions are obtained with version-exclusive Mega Stones - for example, Mewtwonite X can only be obtained in Pokémon X and causes Mewtwo to evolve into Mega Mewtwo X. The item can be traded between versions, however.
  • Mega Evolution (X version) brings an alteration to the Pokémon's typing while Mega Evolution (Y version) does not.
• The Ralts family is currently the only one to have two Mega Evolutions that are a part of a family that branches off.
  • This causes Wally's Ralts to evolve into Gallade instead of Gardevoir (Gallade wasn't available in Gen. III).
• Each Pokémon that Mega Evolves gains exactly 100 points in total statistics, with the exception of Alakazam, who only gains 90 points.
  • This was changed in Sun and Moon as Mega Alakazam's base Special Defense changes from 95 to 105, thus keeping the 100 point-increase consistent.
• Mega Evolution was originally a transformation method, but the method was changed into an evolution method thought to be a transformation method.
  • Mega Evolution is a cross between Evolution and Forme Change.
• Aggron is the only Pokémon to lose a type without any other replacing it after Mega Evolving.
  • Tyranitar, Medicham, and Abomasnow are the only Pokémon who retain their main Abilities after Mega Evolving. Scizor will do the same if it has Technician as its Ability.
  • Slowbro is the only Pokémon whose Mega Evolution alters less than 3 of its stats.
  • Aerodactyl is the only fossil Pokémon that can Mega Evolve.
  • Mega Mewtwo X has the largest stat boost of all Pokémon capable of Mega Evolution, with its Attack rising by 80 points.
    • Diancie has the sharpest drop in stats upon Mega Evolving, with its Defence and Sp.Def falling by 40 points each.
• Rayquaza is the only Pokémon that doesn't need a Mega Stone to Mega Evolve. Instead, it has to learn the move Dragon Ascent and not holding a Z-Crystal.
  • Also, in the Delta Episode of Omega Ruby and Alpha Sapphire in the battle against Deoxys, it is the only Pokémon that is already Mega Evolved when a battle is started.
• In the anime, Mewtwo, Rayquaza, Latias and Latios are able to Mega Evolve without Mega Stones.
• Ash's Greninja is able to utilize a power similar to Mega Evolution without necessarily using it. This is called the Bond Phenomenon, a change of form that matches the power of Mega Evolution and doesn't need a Mega Stone.
  • Ash ends up in a rivalry with a transitioning Alain because of Greninja.
• Even though multiple sources say that a large bond is required to Mega Evolve a Pokémon, in the games, no friendship or affection is required to Mega Evolve a Pokémon (even Pokémon that have just been caught can Mega Evolve).
• As shown in the Pokédex entries for Pokémon Sun and Moon, Mega Evolution gives great pain to Pokémon like Gyarados, Sableye, and Aerodactyl, forcing them to become violent and even sometimes causing harm to them.
• Currently, Mega Altaria is the only Pokémon with a Mega Evolution that has a unique type combination (Dragon/Fairy) which no other Pokémon has. Mega Sceptile also had a unique type combination until Alolan Exeggutor was introduced.
• As shown with Korrina's Lucario, there are occasions where Mega evolution can easily take control of the Pokémon if they aren't fully trained in using the power.
