Mewtwo

Mewtwo is a Legendary Psychic-type Pokémon debuting in Pokémon Red and Pokémon Blue Versions. Mewtwo was created artificially based on the genetic code of Mew to be the ultimate battling Pokémon, though it grew too vicious and powerful to be controlled and escaped. Among all the Pokémon that exist, Mewtwo has the most violent nature. As of Pokémon X and Pokémon Y, Mewtwo can Mega Evolve into either Mega Mewtwo X or Mega Mewtwo Y.

Mewtwo makes a playable appearance as an unlockable fighter in Super Smash Bros. Melee, and as a downloadable fighter in Super Smash Bros. for Nintendo 3DS / Wii U, later appearing in Super Smash Bros. Ultimate as an unlockable fighter, like in Melee. Its appearance in the Super Smash Bros. series is primarily based on the Mewtwo from the first Pokémon anime movie, which was cruel, condescending, and fierce, but also questioned its existence and purpose.

Super Smash Bros.
Mewtwo was planned to be a playable character in Super Smash Bros., but time constraints posed as an issue, so it was left out.

Super Smash Bros. Melee


In Super Smash Bros. Melee, Mewtwo is an unlockable character. Mewtwo appears after the player has played a total of twenty hours of Melee matches with one player, fifteen hours with two players, ten hours with three players, and five hours with four players; alternatively, the player can play 700 Melee matches. Mewtwo must then be defeated on Final Destination to be unlocked.

Mewtwo's moves are powerful and it can jump high, but it is a lightweight fighter, making it easier to launch, and it does not move as fast as other characters; while it has a high air speed, Mewtwo has a low fall speed and its running and walking speeds are low. Mewtwo also floats above the ground, making it an easy target to send flying and even KO at low damage percentages, and it also has low traction. Mewtwo also possesses a strong grab, and its throw moves pack a strong punch as well. Its standard special is Shadow Ball, which charges and fires a ball of dark energy. Its side special is Confusion, which flips opponents onto the ground and deflects projectiles (however, the reflected projectile does not damage opponents). Mewtwo's down special is Disable, which dazes any opponents that it is facing when using the move. Finally, its up special is Teleport, which causes Mewtwo to disappear and reappear in a different location.

Mewtwo does not use its hands to hold items, using telekinetic powers instead, making the items hover before it. A similar style is seen when Mewtwo hangs on a cliff or grabs another character. The only time it does touch an item is when using the Parasol. Mewtwo is voiced by Masachika Ichimura in both English and Japanese.

Super Smash Bros. Brawl
Mewtwo is one of the five characters who did not return in Super Smash Bros. Brawl as a playable character (the other four being Dr. Mario, Young Link, Pichu, and Roy). Data exists on the disc for Mewtwo as a playable character, however, meaning that at one point in development it may have been a character in the game. It does, however, have the appearance of a trophy, which can be obtained by completing All-Star Mode on Intense difficulty.

Super Smash Bros. for Nintendo 3DS / Wii U


Originally, Mewtwo only appeared as a collectible trophy in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U. Additionally, a Mega Mewtwo X & Y trophy appeared exclusively for Super Smash Bros. for Wii U.

During the Super Smash Bros. for Wii U 50-Fact Extravaganza, however, Mewtwo was confirmed to appear as a downloadable fighter for Super Smash Bros. for Nintendo 3DS / Wii U. It is one of three cut characters from Super Smash Bros. Brawl to return, alongside Dr. Mario and Roy (the latter also appearing as a downloadable fighter). Mewtwo was released publicly as paid content at the Nintendo eShop on April 28, 2015, but players who had registered Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U onto their Club Nintendo account before the end of March 31, 2015 received free download codes for Mewtwo on April 15, 2015. Mewtwo's design as a playable character in this game is closer to its current appearance, and it is now voiced by Keiji Fujiwara.

While Mewtwo's moveset is identical to that of its Super Smash Bros. Melee incarnation, it has been given a Final Smash: Psystrike, in which it Mega Evolves into Mega Mewtwo Y and delivers a mental attack. Some of its other moves have also been altered to increase their effectiveness. Mewtwo is also much lighter (only being heavier than Jigglypuff), and moves faster than in Super Smash Bros. Melee, while keeping its attack power. Additionally, Mewtwo still offers one of the highest air speed attributes in the game, losing only to Yoshi and Jigglypuff, but its high air speed is offset by very low air acceleration, and its falling speed is above average as well.

When Mewtwo is downloaded, it can appear in all the solo game modes, except for Events. In All-Star mode, Mewtwo appears between Diddy Kong and Pikachu. However, Mewtwo's inclusion has no effect on any of the challenges.

Super Smash Bros. Ultimate
Mewtwo reappears as an unlockable playable character in Super Smash Bros. Ultimate. Mewtwo's mobility is improved, while its double jump is made faster.

Shadow Ball


Shadow Ball is a Ghost-type move in the Pokémon series, and Mewtwo's standard special move. When used, Mewtwo stands in place and charges up a ball of dark energy; the charging deals electric damage in Super Smash Bros. Melee. Unlike other auto-charging moves, Mewtwo continues to charge even when the move is fully charged; it can only be stopped by firing, shielding, or tilting the control stick to automatically roll. Charging the move allows it to travel farther and deal greater damage and knockback. When fired, the ball travels forward in a waving motion. The move also has a recoil effect when fired which is greater when fired in the air, pushing Mewtwo back depending on how much the move was charged before firing.

Mewtwo's forward throw also involves him firing Shadow Balls in rapid succession at opponents.

Confusion


Confusion is a Psychic-type move from the Pokémon series used as Mewtwo's side special move. When used, Mewtwo swipes its hand, causing a dark aura to appear around it, tossing opponents to the ground and damaging them if they are close enough. Confusion can also deflect projectiles, though in Super Smash Bros. Melee, deflected projectiles cannot damage the original user, but in Super Smash Bros. for Nintendo 3DS / Wii U, all projectiles deal damage when reflected. When used in the air, Mewtwo does a slight hop. The move can also bypass opponents' shields.

Teleport


Teleport is a recurring Psychic-type move appearing in every installment of the main Pokémon series, and appears as Mewtwo's up special move. Mewtwo disappears in a flash of light, and reappears depending on the direction the player holds on the control stick, similar to Zelda's Farore's Wind. Like any other up special attacks, Mewtwo is left in a helpless state if he is in the air after using Teleport.

Disable


Disable is Mewtwo's down special move, based upon the recurring Normal-type move from the Pokémon series. Mewtwo fires a beam from its eyes in the direction that it is facing, temporarily dazing any nearby opponents caught by it and damaging them; the opponent must be facing Mewtwo and at around its eye level for the move to work, however. The move also dazes opponents for longer if they have a higher damage percentage. In Super Smash Bros. Melee using Disable on an already dazed opponent causes them to fly off, though in Super Smash Bros. for Nintendo 3DS / Wii U this only deals more damage. If the move is used on an opponent in the air, then they will only briefly flinch.

In Super Smash Bros. for Nintendo 3DS / Wii U, Mewtwo's stance when using Disable is different than in Super Smash Bros. Melee, with its lower head position allowing the move to hit smaller opponents more easily.

Psystrike
Psystrike is Mewtwo's Final Smash. In the Pokémon series, it is a Psychic-type move learned by Mewtwo at level 100, and is Mewtwo's signature move as of Generation V. When activated, Mewtwo Mega Evolves into Mega Mewtwo Y, then fires a large ball of psychic energy across the screen in the direction Mewtwo is facing, stunning any opponents in its path. The stunned opponents then take heavy damage and are launched away as Mewtwo returns to normal. Opponents can be stunned even if they are in the air.

Super Mario Maker
Mewtwo is one of the Costume Mario costumes that can be unlocked in Super Mario Maker, either with a Mewtwo amiibo or as a random unlock by completing the 100 Mario Challenge. Mewtwo's sprite is based on its overworld sprite from the Nintendo DS Pokémon games, though like the other Pokémon costumes in the game (excluding the Event Course costumes) Mewtwo does not have any unique sound effects, instead using the default Super Mario Bros. sounds.

Palutena's Guidance
The following dialogue applies also to Lucas, Roy, Ryu, Cloud, Corrin, and Bayonetta; all DLC characters, like Mewtwo.


 * Pit: Who is THAT?
 * Palutena: I have no data on this fighter. I can't believe it!
 * Viridi: It must be an intruder from another dimension!
 * Pit: Whoever it is, the goal remains the same: to fight and win!

amiibo

 * Created from modified Mew DNA, Mewtwo was designed to be the ultimate Pokémon. It didn't take on any of Mew's kinder traits and only uses its intelligence to destroy its enemies. Or...so it seems. Perhaps it just feels frightened or even tormented, and that's why it lashes out. Whatever the reason, Mewtwo is not to be messed with.

Trivia

 * Mewtwo never speaks when the language is set to English (or, in the PAL version, at all); it makes only grunts, laughs, and other noises. However, it does speak telepathically on the results screen when the language is set to Japanese.
 * When in metal form in Super Smash Bros. Melee, Mewtwo does not make clanking noises, even when it lands; in Super Smash Bros. for Nintendo 3DS / Wii U, while it still does not clank while moving, it does when it lands.
 * The tagline for Mewtwo's Super Smash Bros. for Nintendo 3DS / Wii U trailer, "Mewtwo Strikes Back!", is a reference to the name of the first Pokémon movie.
 * Mewtwo's depiction as a lightweight fighter in the Super Smash Bros. series is likely due to its floaty attributes and its tendency to float while moving, which are both mentioned in its trophy descriptions. Its lightweight status may also be a reference to the Pokémon games, where its defenses are on the low side when compared to most other Pokémon who share its base stat total.
 * Mewtwo is thus far the only Legendary Pokémon to be playable in the Super Smash Bros. series.
