Mewtwo

"Fool, trying to stop our battle."

- Mewtwo

Mewtwo is a psychic genetic Pokémon cloned from Mew, the Legendary Pokémon ancestor of all Pokémon. Interestingly, Nintendo, for a time, considered Mewtwo the secondary antagonist of Pokémon, behind Giovanni. Mewtwo can be considered evil, but more misunderstood because of the way it was created but Mewtwo is later redeemed and helps the main cast.

Pokemon
In the main Pokémon games of Red, Blue, Yellow, FireRed, LeafGreen, HeartGold, and SoulSilver, Mewtwo is only encountered in Cerulean Cave, with no real storyline significance and can be battled after beating the game. It is seen at level 70. In X & Y, Mewtwo is found at level 70 in the Unknown Dunegon after beating the game. It is suggested that the scientists of Team Rocket created Mewtwo in the Pokémon Mansion on Cinnabar Island and that Mewtwo destroyed the Pokémon Mansion in its wake as it escaped its human captors and creators.

Mystery Dungeon
Mewtwo also has a role in some of the spin-offs. It is a villain in Pokémon Mystery Dungeon - Red/Blue Rescue Team, it is at the end of a 99 floor dungeon called Western Cave. It attacks and defeats Blastoise & Charizard when they attempt to face it and can be fought as a boss after Ho-oh has been recruited. It is defeated by the rescue team and joins them.

Super Smash Bros.
Mewtwo was meant to be in Super Smash Bros., but was officially cut for unknown reasons.

Super Smash Bros. Melee
Mewtwo is also among the cast of Super Smash Bros. Melee, and considering its role in the last event match of the game, where the player faces a tag team of three villains (along with Giga Bowser and Ganondorf), it is considered a villain by the game.

Super Smash Bros. Brawl
Despite not being a clone like the other cut characters, Mewtwo did not return to Brawl as a playable fighter. It only appears in the game as a trophy. Many fans believe it was replaced by Lucario similar to how others believe that Roy of Fire Emblem was replaced by Ike. However, by looking inside the disc's data one can discover files for Mewtwo indicating it was intended to also be playable in Brawl.

Super Smash Bros. for Nintendo 3DS/Wii U
After being absent from Brawl, Mewtwo returned as a playable fighter in Super Smash Bros. for Nintendo 3DS & Wii U as a downloadable character. It was confirmed to be a playable character during the Super Smash Bros. for Wii U: 50-Fact Extravaganza NIntendo Direct presentation on October 23rd, 2014. For players that registered both Super Smash Bros. for NIntendo 3DS and Wii U respectively on Club Nintendo by March 31, 2015, recieved download codes for both versions in their emails on April 15th, 2015. Mewtwo has since been made available as of April 28th, 2015.

After being defeated the first time, Purple Eyes enhances and controls Mewtwo and uses it itself. After its defeat it banishes Purple Eyes in anger before leaving.

Mewtwo Strikes Back
See full page for this: Mewtwo (Anime)

Mewtwo serves as the titular main antagonist of the film.

Mewtwo was created by Team Rocket by cloning DNA from a Mew fossil. It was Team Rocket's intention to create the most powerful Pokémon. However, Mewtwo was angered by the team as it heard that it was to be controlled by them, and that it may not be part of God's creation (Japanese version), and in its fury, destroyed the lab where it was created, and killed all the scientists with its intense psychic powers. It then allied himself with Giovanni under the promise of learning to control its powers, although it later rebelled from Giovanni after learning that Giovanni's claim of partnership had been a lie, and it had already been sickened by Team Rocket's actions towards Pokémon. Believing humans as oppressors of Pokémon, it vowed to exterminate humans and all Pokémon that sided with them, believing it to be its "purpose". It also wishes to exterminate Mew, as it believed itself was vastly superior to its genetic counterpart. It eventually saw the errors of its ways shortly after Ash Ketchum sacrificed himself to stop their fighting, and removed their memories to avoid being tracked down.

Its backstory was expanded upon, where it interacted with several clones of a Charmander, Squirtle, Bulbasaur, as well as a clone of Amber, the daughter of Dr. Fuji. It was eventually distraught over its friends, especially Amber's premature death, which also resulted in the scientists injecting it with a serum that removed any memory of her, which is strongly implied to have impacted its behavior in the film.

Mewtwo Returns
Mewtwo serves as an anti-hero here. Ite was hiding in Kena Mountain with the other clones. It saved a bus with passengers, but it feels no compassion for the humans. When Giovanni managed to find both Mewtwo and the others clones, he decided to help all of the Pokémon. It was proven to be a great ally for Ash and his friends. Later when Ash told it he will tell Professor Oak about him and the source, Mewtwo wanted to erased their memories again. But Meowth managed to convinced Mewtwo that they should keep their memories. Mewtwo agreed to let them remember it and the others, while only erasing the memory of the people who wanted to destroy Mewtwo.

The Mastermind of Mirage Pokémon

 * Main Article: Mirage Mewtwo

Mewtwo makes an appearance as the secondary antagonist in the Special: The Mastermind of Mirage Pokémon. However, in this version, Mewtwo is a Mirage Pokémon created by Dr. Yung.

Pokémon Origins
Mewtwo appears as the ultimate adversary of Red in Pokémon Origins. As in the games, it is encountered in Cerulean Cave after defeating Blue. In a hard battle that wiped out almost all of Red's Pokémon, Mewtwo is defeated by Charizard after it Mega Evolves into Mega Charizard X. With Mewtwo captured after several tries, Red then had all 150 known Pokémon.

Pokemon Adventures Manga
In the manga it was created during the Red, Blue, and Green story arc by the Gym Leader and Team Rocket's former scientist Blaine who used one of his own cells in the process though as a side effect whenever Mewtwo fights it causes Blaine immense pain due to the cellular connection with Blaine. Mewtwo first appeared attacking Blaine, and it was only with Red's strategy that Mewtwo is caught in a Pokéball.

In the Yellow arc, by this point it and Blaine have become good friends and fight alongside Yellow against Lance of the Elite Four, but Blaine was forced to call it back before its fall due to their connection, though Yellow with Red's Chu (Pikachu) would use the same strategy Mewtwo tried earlier to win.

In the Gold, Silver, and Crystal arc during the Gym Leader completion, thanks to the powers of Entei's holy flames, Mewtwo's connection to Blaine is severed to where Mewtwo can now fight without affecting its creator, allowing it to leave Cinnabar Island and be free.

In the FireRed and LeafGreen arc Mewtwo reappears and aids Red, Blue, Green, Yellow and Silver against Deoxys and Giovanni. In the end it helped the Kanto Pokedex holders and Silver prevent Sird from recapturing Deoxys, and while the five of them were turned to Stone, Mewtwo was not. While it has not been seen since, it was mentioned by Sird in the Diamond and Pearl arc to have been tracking her before he lost her.

Special abilities
Mewtwo is highly skilled with Psychic powers. It can levitate through use of telekinesis, speak telepathically, and can take control of another living being's mind. It has a powerful signature move, Psystrike, and it is also known for its powerful Shadow Ball and Aura Sphere. Mewtwo is also capable of wielding various types of attacks (but to a lesser extent than Mew). To exert its powerful psychic abilities, it will stay motionless for long periods of time in intense concentration to raise its capabilities to their maximum power.

In the Pokémon Adventures manga, Mewtwo fights with a highly skilled combination of Psywaves and a giant spoon for long range and close range battles, respectively.

In the anime, Mewtwo also has the ability to telekinetically create a massive hurricane and is constantly protected from harm inside a reflective sphere of psychic energy. In the English dub, it is claimed that the hurricane was powerful enough to destroy the planet, as well as Mewtwo being able to block a Pokémon's "special abilities." Mewtwo can also "communicate" with humans via telepathy, and was also capable of instant regeneration, allowing it to survive what would normally be fatal blows. This was especially evident when a computer, deducing Mewtwo as a threat shortly after bursting out of its containment field, shot Mewtwo with a laser that was potent enough to temporarily kill Mewtwo, only to regenerate from its wound and revive itself, as well as it regenerating from a flamethrower blast. According to the dub of Mewtwo Returns, its psychic abilities were ineffective against automated machines.

Trivia
