—Description from the Super Smash Blog.

Mewtwo is a veteran fighter in Super Smash Bros. Ultimate, first playable in Super Smash Bros. Melee. It was confirmed during Nintendo's E3 2018 presentation.

When unlocked, it is fought at Spear Pillar.



  • Can Wall Jump.
  • Fast dash speed.
  • Many of its attacks involving dark energy have disjointed hitboxes.
  • Very good air dodge.
  • Jab has little ending lag, being capable of combo'd into grabs and other fast attacks.
  • Down Aerial can Meteor Smash.
  • Great gimping potential, which aided by its recovery makes Mewtwo a very powerful character for attacking offstage.
  • Can make use of many mindgames using Teleport and air dodge. This also makes its recovery versatile and less predictable.
  • Very good recovery with Teleport, backward aerial Shadow Ball, and Confusion.
  • Fully charged Shadow Ball deals a high amount of shield damage.
  • Confusion can throw opponents off-balance, goes through shields and reflects projectiles.
  • Disable can stun opponents for longer periods of time the higher their percentage is.


  • Has large hurtboxes and is floaty, making him an easy target.
  • Very light weight.
  • Most tilts have considerable ending lag.
  • All its tail based attacks have their sweetspot at the base of its tail near the body, with a sourspot at the tip. This means Mewtwo must be at very close range to its opponents to deal maximum damage and knockback with any tail attack.
  • Shadow Ball lacks hitboxes while charging.
  • Disable requires eye-contact range, meaning it will not hit if opponents have their backs turned to Mewtwo and it cannot stun opponents in mid-air.
  • Confusion is an unreliable reflector, and has a fair amount of end lag, meaning Mewtwo cannot Pinball very well with other reflectors.


Changes from SSBWU/3DS


  • In Mewtwo's Final Smash, all opponents caught in it will be launched at once, instead of one by one.
  • Several of Mewtwo's attacks, such as up-smash, have enhanced visuals.
  • When an opponent is hit with Confusion, Mewtwo will now always be able to act before the opponent.

In competitive play

Initially, the community's perception on Mewtwo was better than his Smash 4 iteration, who was widely considered a top-tier character. This was because of Mewtwo's improved KO power; its main weakness, its endurance, being seemingly toned down thanks to increased weight; and benefits from the universal mobility changes. As such, many players believed Mewtwo would become a high- or even top-tier character, with potential to be one of the best characters in the game.

However, as time went on, Mewtwo's flaws becoming more prominent. Most notoriously, Mewtwo's extended tail hurtbox caused it to be clipped by many attacks from a noticeable range. Additionally, its disadvantage state has been significantly nerfed due to the changes to air dodging and the character's increased hurtbox size. Due to these nerfs from Smash 4, Mewtwo had little impact in Ultimate's early metagame, with most of Mewtwo's playerbase from Smash 4 dropping it in favor of other characters. Although SDX saw initial success with the character, he would eventually drop the character, leaving Mewtwo with no high-level representation.

Game updates slightly addressed some of Mewtwo's biggest flaws, allowing it to gain more attention in the eyes of some players. Dedicated players such as Zenkai and ???? also began to see solid placements, with both players placing 49th at Frostbite 2020. Despite this slow improvement in representation, the character's playerbase offline still remains somewhat small, and some of its more meaningful buffs have come during the COVID-19 pandemic, making it hard to tell how these changes will improve Mewtwo's viability in the long run.

In the online metagame, thanks to the aforementioned buffs, Mewtwo has found success thanks to the efforts of players such as WaDi and Chewie. The former uses Mewtwo as a secondary and has defeated players such as Sparg0, naitosharp, and 8BitMan. The latter uses Mewtwo as a main and has seen above average placements at major Wi-Fi Warrior Rank tournaments, including 13th at the SWT: NA Southwest Ultimate Online Qualifier and 25th at The Box: Lunch Box 10.

Classic Mode: Psychic Control

Each round, Mewtwo is allied with previous opponents under the notion that its teammates are under its mental control, these teammates typically represent characters that have been brainwashed in their respective home series.

Role in World of Light

Mewtwo was among the fighters that were summoned to fight the army of Master Hands.

During the opening cutscene, Mewtwo was present on the cliffside when Galeem unleashed his beams of light. Mewtwo and Zelda attempted to reflect the beams using Confusion and Nayru's Love respectively: this effort failed, with both being vaporized and placed under Galeem's imprisonment, along with the rest of the fighters (excluding Kirby).

Mewtwo was one of the many fighters that fell under Dharkon's control upon Galeem's first defeat. It can be found in the Mysterious Dimension sub-area, where its location will be accessed during the quiz segment asking which spirit cannot be inhaled by Kirby (the answer for Mewtwo being Whispy Woods).
