Mewtwo (ミュウツー Myūtsū?) is a fictional creature from the phenomenally popular and expansive Pokémon media franchise. It was introduced as the "final Pokémon" in the very first set of games in the franchise. It was included in Super Smash Bros. Melee as a playable character and in Super Smash Bros. for Nintendo 3DS and Wii U as a downloadable character.

Character Description

Mewtwo is among the 151 Pokémon initially introduced in the First Generation, along with Pikachu, Jigglypuff, Charizard, Squirtle, and Ivysaur as the final 150th Pokémon catchable in the game, whereas Mew was only obtainable through special means.

Mewtwo is a fairly anthropomorphic Psychic-type Pokémon with a pale purple body and vaguely feline qualities, having been cloned from Mew. Like all Pokémon, Mewtwo's design concepts are illustrated in the Pokémon RPGs via the various Pokédex entries available within the games. However, the scientific power of humans failed to endow it with a compassionate heart. Thus, it has one of the most savage hearts among Pokémon, carrying a disposition vastly different from that of Mew, and thinks only of defeating its foes. Much like Bowser or Ganondorf, villains who appear alongside Mewtwo in Melee, Mewtwo is indirectly an antagonistic character hailing from the Pokémon franchise.

Powers & Abilities

Mewtwo is an extremely powerful Psychic-type Legendary Pokémon. As it is a Legendary Pokémon, there is only one Mewtwo in the entire Pokémon universe and has above average stats compared to an average Pokémon. Mewtwo was a failed attempt of cloning the Legendary Pokémon Mew by Team Rocket. Mewtwo destroyed Team Rocket's laboratory on Cinnabar Island and escaped into seclusion. It currently resides in the depths of Cerulean Cave though it does move around the Pokémon world, living in different places every once in a while such as the Unknown Dungeon in the Kalos region as it prefers to live in caves, far from humans. It is one of the few artically created Pokémon along with Castform, Porygon, Porygon2, and Porygon-Z. Due to this, Mewtwo is a genderless Pokémon and is neither male nor female.

As Mewtwo is a Psychic-type Pokémon, it's attack center mainly around its Psychic abilities such as Psychic, Future Sight, Dream Eater, and it's signature attack, Psystrike which is a unique attack in that it does physical damage to an opponent even though it's a Psychic-type attack which aren't typically physical based attacks. Mewtwo can also learn Shadow Ball (a Ghost-type attack), Flamethrower, Thunderbolt, Energy Ball (a Grass-type attack), Ice Beam and the list goes on (These attacks can only be learned through TMs). This is due to Mewtwo being artificially created, as Team Rocket tried to make it the most powerful Pokémon in the world. Mewtwo also has ESP and has telepathy, allowing it to read the minds of others and allowing it to speak telepathically even though Pokémon can't usually talk. Mewtwo can also perform mind control over its foes (as shown in the first Pokémon movie when it controlled Nurse Joy) and manipulate their mind and feelings. Mewtwo can also Mega Evolve into two different forms: Mega Mewtwo X and Mega Mewtwo Y. Mega Mewtwo X gains an additional Fighting-type making it a Psychic and Fighting-type with increased physical stats. Mega Mewtwo Y remains a Psychic-type but is even stronger due to increased special based attack stats, making Mega Mewtwo Y the strongest Pokémon to date.

Even though Mewtwo remains a powerful Pokémon, it does have a few weak points. It is weak to the Ghost-type, Bug-type and Dark-type Pokemon. Dark-types also have another advantage in that they are immune to Psychic-type attacks. Mewtwo is also rather frail in the defensive stats and it can't take hits too well, especially after Mega Evolving, into its Mega Y form. As it is a Legendary Pokémon, Mewtwo can't evolve into or from any other Pokémon besides being able to Mega Evolve.

In Super Smash Bros.

Mewtwo was planned to be a playable character in the original Super Smash Bros., but it is unknown why he was eventually cut.

In Super Smash Bros. Melee

As a Playable Fighter

Main article: Mewtwo (SSBM)

Mewtwo made its Smash-series debut as an unlockable character in Melee; it is interesting to note that it could have appeared in the previous game in some form but didn't. It is much more difficult to unlock than most other secret characters in Melee, however; it can be unlocked after either playing 20 straight hours of Vs. Mode matches (5 hours for four players), or playing 700 Vs. mode matches.

An easy way to unlock Mewtwo is to leave a versus match overnight. Upon return, just finish the match, and the Mewtwo challenge will begin. Defeat the challenge to unlock Mewtwo.

Despite being renowned for its power and battle prowess in the Pokémon Series, Mewtwo is often criticized by players because of his gameplay problems and negative build qualities (though since dedicated Mewtwo players have found new ways to use it, the criticism has softened in recent years), and it has a low rank in the current Melee tier list as a result, finding itself in 21th place.

In the Pokémon RPGs, from Pokémon Gold and Silver onward, every Pokémon species has a 1/8192 chance of being alternatively-colored, and such individuals are called "Shiny Pokémon" by fans. The shiny Mewtwo's coloration is green instead of purplish pink, and this is one of Mewtwo's alternate costumes in the game.

As a Collectible Trophy

By tradition, Mewtwo as a playable character is featured on its personal three trophies. Its normal trophy is acquired by beating the Classic mode with Mewtwo on any difficulty, and its Smash Red and Smash Blue trophies are acquired the same way by beating the Adventure and All-Star modes, respectively. Its Classic mode trophy reads:

A genetically created Pokémon, Mewtwo is the result of many long years of research by a solitary scientist. Although Mewtwo was cloned from the genes of the legendary Pokémon Mew, its size and character are far different than its ancestor. Its battle abilities have been radically heightened, making it ruthless.

In Super Smash Bros. Brawl

As a Character

Since Brawl's Lucario shares some properties with Melee's Mewtwo, it was originally believed that Lucario indeed replaced Mewtwo, much like it was thought that Ike had replaced Roy. However, there is no evidence that Lucario was intended to "replace" or exist as a clone of Mewtwo in Super Smash Bros. Brawl. Instead, by intensive hacking, it was confirmed that Mewtwo was intended to return, but was scrapped due to time constraints.

As a Collectible Trophy

Mewtwo Trophy Render

Mewtwo appears in Brawl as a collectible trophy. This trophy can be obtained by completing All-Star mode on Intense difficulty. The trophy describes Mewtwo's appearance in the Pokémon games, and makes no reference whatsoever to its appearance in Melee:
A Genetic Pokémon. This legendary Pokémon was based on a recombination of Mew's DNA, created by a scientist after years of research. However, Mewtwo greatly differs from Mew in both size and personality and it is said to have the most twisted and savage heart among all Pokemon. Mewtwo has incredibly high combat abilities and uses Psychic- type attacks.

In Super Smash Bros. for Nintendo 3DS and Wii U

Main article: Mewtwo (SSBWU/3DS)

Mewtwo is a playable fighter in Super Smash Bros. for Nintendo 3DS and Wii U. People who own both Super Smash Bros. For 3DS and For Wii U were able to receive Mewtwo for free if they registered both games on Club Nintendo by March 31st, 2015. Players who did not register both games on Club Nintendo are able to buy Mewtwo starting April 28th, 2015. His specials are Confusion, Shadow Ball, Disable and Teleport, with his new final smash being Psy-Strike, where Mewtwo Mega Evolves into Mega Mewtwo Y and uses telekinesis to damage other players.


  • In Super Smash Bros. Brawl, hacking reveals that Mewtwo was planned to be a playable character but was scrapped late in development due to programming issues and resources being focused on the Subspace Emissary story mode.
    • Out of all the scrapped fighters in Super Smash Bros. Brawl, Mewtwo contains the most data out of any other character, with a working character model and voice recordings.
  • He is the first Downloadable character in the history of the series (in Super Smash Bros. for Nintendo 3DS and Wii U), followed by Lucas, Roy & Ryu.
  • Mewtwo, along with Roy, Dr. Mario, Pichu, and Young Link, did not return in Super Smash Bros. Brawl.
    • Out of the playable characters that didn't return in Super Smash Bros. Brawl, Mewtwo was the only character who was not a clone of another character.
  • It is a common theory amongst fans that Lucario replaced Mewtwo. This theory is hinted with the fact that Lucario shares two of the exact same moves as Mewtwo, his forward Smash and neutral Special Attack. This was proven false, as Mewtwo was found in the game's files with a full skeleton and his own victory theme. Not only that, but Mewtwo returned in Super Smash Bros. for 3DS and Wii U as a DLC fighter. He was available for free to anyone who redeemed both versions of the game on Club Nintendo before March 31, 2015. Mewtwo was available to everyone else for $3.99
  • Mewtwo, Dr. Mario & Roy are currently the only characters that were cut from a Super Smash Bros. game (Super Smash Bros. Brawl) and returned in the next Super Smash Bros. game (Super Smash Bros. for Nintendo 3DS and Wii U).
    • Coincidentally, the three characters are part of the Forbidden 7, the 7 characters that were planned for Brawl and have been found in the game's code, but never made it to the final release due to time constraints.
