Mewtwo (ミュウツー, Mewtwo) is a playable character in Super Smash Bros. 4. Its return to the series was announced during the Super Smash Bros. for Wii U 50-Fact Extravaganza on October 23rd, 2014. Mewtwo is the first downloadable character in Super Smash Bros. history, and was made available on April 28th, 2015. However, it was made available at no cost as early as April 15th, 2015 for players who registered both Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U on Club Nintendo by March 31st, 2015.
Mewtwo is ranked 10th out of 55 on the tier list, placing it in the A tier. This is a significant improvement from its low-tier placement in Melee, where it was ranked 21st out of 26. Mewtwo boasts excellent mobility: in addition to retaining its very fast air speed, its walking and dashing speeds have become drastically faster, and it can now wall jump.
Mewtwo also possesses a flexible combo game. Its neutral attack is a very reliable jab cancel, even at high percentages, while its down tilt and fast falling up aerial both possess a variety of follow-ups at low to high percentages. Like in Melee, Mewtwo's grab game is potent: its forward throw is tied for the most damaging throw of its kind in the game, whereas its back and up throws are viable KOing options. Mewtwo also boasts a respectable number of potent KOing options: in addition its up and back throws, its smash attacks, forward aerial, and fully charged Shadow Ball each possess considerable power.
Lastly, most of Mewtwo's special moves also have improved utility. Fully charged Shadow Ball has a larger hitbox and longer range; Confusion now functions as a traditional reflector and now grants a small vertical boost when used in midair; and Disable's stun effect has a longer duration.
However, Mewtwo's infamous frailty has become even more pronounced, owing to its larger size and much lighter weight. This, in turn, is compounded by its slightly below-average frame data and slow double jump, which force it to rely on its neutral aerial, forward aerial, or Teleport to escape pressure more often than not.
After initially being a poorly perceived character upon its release, game updates significantly improved Mewtwo's viability over time. This has been reflected by players such as Abadango, Rich Brown, and WaDi consistently achieving high placings in competitive play, whose successes have helped Mewtwo achieve top-tier status as of SSB4's second tier list.
Mewtwo is a character whose majority of attributes are unusually polarizing, with only its falling speed and gravity being average. It is tall, yet is the second lightest character in the game, being surpassed only by Jigglypuff. By extension, Mewtwo's hurtbox has a deceptive size: although it is larger than in Melee, its model's adjusted z-axis position has resulted in its hurtbox ending approximately at its digits, ankles, and the base of its tail. As a result, the majority of Mewtwo's tail now lacks hurtboxes unlike in Melee, which makes all but the base of its tail immune to opposing hitboxes. However, its hurtbox will still extend slightly when it attacks, whereas its digits, ankles, and the base of its tail will leave their z-axis positions when it is in hitstun or while tumbling.
In regard to grounded mobility, Mewtwo's walking speed is tied with Charizard's for the fifteenth fastest in the game, whereas its dashing speed is the seventh fastest in the game. However, its traction is also tied with Charizard's for the second lowest in the game. This polarization is also apparent with Mewtwo's aerial mobility: its air speed is the third fastest in the game, yet it has slow air acceleration, while its double jump is the highest in the game, yet accelerates slowly at its beginning. As a result of these attributes, landing and approaching safely can be difficult. Unlike in Melee, Mewtwo is capable of wall jumping.
Mewtwo's air game is highly potent. Its air dodge makes it disappear briefly and is the fastest one in the game, thanks to it concluding after 28 frames. Mewtwo's aerial moves boast impressive power thanks to their respectable damage outputs and very high knockback scaling, yet are also useful for partaking in combos. Neutral aerial's hitbox has a long duration, which allows it to punish air dodges or start combos upon landing as the opponent is being hit. Forward aerial is Mewtwo's fastest aerial, thanks to it hitting on frame 6. When coupled with its power and range, it can either combo into itself at low percentages, or KO outright at high percentages.
Back aerial has very large range, which enables it to edge-guard reliably, yet also combo into itself at low percentages or KO outright at high percentages. Up aerial, like back aerial, has a very large range, which enables it to partake in combos or juggles. Its base hitbox's high knockback scaling also makes it KO reliably near the upper blast line. Lastly, down aerial is a very powerful meteor smash when sweetspotted, yet is also strong enough to KO on-stage opponents quite reliably. Due to it hitting on frame 15, however, it is Mewtwo's slowest aerial, and has the highest amount of landing lag out of its aerials.
Despite having been toned down since Melee, Mewtwo's grab game is among the most potent in SSB4. When all of its Shadow Balls hit, forward throw is tied with Ganondorf and maximum Aura Lucario's forward throws as the most damaging throws of their kind in the game; this makes it useful for both damage racking and refreshing its stale moves. Up and back throws are among the strongest throws in the game, making them viable KOing options. Down throw lacks true combo potential, but nevertheless has mindgame potential, thanks to it launching opponents just out of counterattacking range. However, Mewtwo's overall grab range and pummel are both merely average. Regardless, the potency of its grab game supplements its air game, as it can allow Mewtwo to inflict a considerable amount of damage with just a few moves.
In comparison to its air and grab games, Mewtwo's ground game is a mixed bag. While generally powerful, all but a few of its grounded moves suffer from noticeable ending lag, which makes them risky when they are whiffed, shielded, or dodged. Its neutral attack is very useful: it can easily jab cancel and even out-prioritize many moves, which in turn enables Mewtwo to better utilize its grab game and quickly initiate combos when followed up with up tilt, down tilt, or Disable. Down tilt, in particular, is a very effective move: its long range, launching angles, and minimal overall lag make it very useful for starting combos and decent for spacing or shield stabbing. Up tilt can combo into Mewtwo's aerial moves and potentially itself on many characters even at high percentages, so long as it hits them with its near hitboxes.
Forward tilt has good range, very high knockback scaling, and can be angled, all of which makes it decent for spacing. However, its very low base knockback makes it unable to KO at reasonable percentages. Although it is punishable, dash attack's respectable range has increased even further, thanks to its hitboxes being re-positioned outward, and its newfound disjointed hitbox. Lastly, Mewtwo's smash attacks have above-average strength and distinct perks: forward smash has the longest range; up smash hits multiple times and is a useful anti-air option; and down smash has the lowest amount of ending lag.
Mewtwo's special moves are powerful, yet risky, much like its ground game. Shadow Ball has impressive utility regardless of its charge: it is useful for zoning or stopping approaches when uncharged, whereas it is one of the strongest and fastest projectiles in the game when fully charged. Teleport grants considerable horizontal momentum and renders Mewtwo invulnerable for a split second, which makes it a safe recovery overall. Confusion, which was notorious in Melee for being virtually useless, has been buffed considerably. In addition to functioning as a long-ranged command grab that can bypass disjointed hitboxes, it now functions as a proper reflector, which improves Mewtwo's neutral game by allowing it to counteract opposing projectiles. Confusion's utility also extends to Mewtwo's recovery, as it now grants a slight vertical and average horizontal boost during its first use in midair, and can completely reverse both its aerial momentum and direction. Lastly, Disable is a risky set-up option, but it can guarantee openings for combos and KOs if it connects, which is further supplemented by its stun duration having been increased since Melee.
Despite Mewtwo's strengths, it has a few notable and fairly exploitable weaknesses. The most apparent of these is its frailty; Mewtwo's very light weight makes it very easy to KO, while its tall frame, average falling speed, and average gravity collectively make it easier to combo and juggle compared to other characters of its size and weight. Furthermore, Mewtwo lacks an effective aerial attack that can interrupt combos, whereas an attempt to Teleport out of combos can lead to it being punished because of its ending lag, momentum, and start-up lag having been increased since Melee.
The majority of Mewtwo's moveset also possesses some restrictions in spite of their advantages. Despite its aforementioned hurtbox properties, Mewtwo's tail-based attacks are still susceptible to being countered, owing to the base of its tail being a part of its hurtbox. Fully charged Shadow Ball has recoil when used in the air, which can cause an inadvertent self-destruct while off-stage. Disable is punishable if it whiffs and can be reflected because of its status as a projectile, the latter of which can easily lead to a fatal turnabout against Mewtwo at high percentages.
Aside from forward aerial and fully charged Shadow Ball, the rest of Mewtwo's KOing options can be difficult to land. Up and back throw can be risky to attempt because of its aforementioned average grab range. Forward and down smash have slow start-up lag, whereas up smash has minimal horizontal range below its blast of dark energy. Despite their speed and accuracy, forward aerial and Shadow Ball's KO potentials can be hindered via staleness because of their frequent usage in Mewtwo's combos and neutral game, respectively. Lastly, its frame data is slightly below-average, which makes its attacks even more prone to punishment if they are not spaced well. As a result, Mewtwo can pressure effectively, yet is also vulnerable to pressure. It is also at a distinct disadvantage in a custom moveset environment, as it lacks custom moves because of its status as a DLC character.
In regard to playstyle, Mewtwo's is an odd combination of styles: it fits the archetype of a glass cannon, yet typically relies on bait and punish tactics and defensive maneuvers to keep opponents from performing rushdowns and capitalizing on its very tall frame and extremely light weight. This does not mean Mewtwo is forced to rely on turtling, however, as its outstanding mobility, excellent air game, and overall powerful moveset make it a force to be reckoned with. As such, Mewtwo is a "high-risk, high-reward" character with a fairly high learning curve, as it has to capitalize on reads more often than not because of its frailty and susceptibility to pressure.
In a similar manner to Marth, Mewtwo was initially poorly regarded in SSB4's metagame because of its most serious flaws from Melee being worsened, which resulted in it suffering from low representation and poor results. After being heavily buffed in game updates, Mewtwo has received more representation and better results in the tournament scene, with its notable players including Abadango, Rich Brown and WaDi. Following Abadango winning Pound 2016 while almost exclusively using Mewtwo, it is now regarded as a much better character than initially thought, with the general consensus being that Mewtwo warranted a spot as a high-tier character before it was officially reassessed as a top-tier character within the current tier list.
Changes from Super Smash Bros. Melee
Mewtwo has been drastically buffed in its transition from Melee to Smash 4, especially owing to the handful of buffs it has received within the game updates. One of its most useful buffs were to its mobility; its walking, dashing, and air speeds are much faster, its jump and double jump are higher, it can now wall jump, and its techs' now-traditional animations make it less susceptible to tech-chasing. Mewtwo's air dodge has also improved: in addition to making it disappear, it is now the fastest in the game, while the removal of directional air dodges now enables it to retain Mewtwo's aerial momentum (although it also removes Mewtwo's ability to wavedash). Mewtwo's model also underwent very subtle, yet beneficial tweaks: its larger size increased the range of its tail-based attacks, while its model's re-positioning within the z-axis has resulted in its hurtbox having a deceptive size.
Mewtwo's moveset has been adjusted so as to be more consistent and practical. Confusion, in particular, has drastically improved: it now functions as a traditional reflector, has considerably less ending lag, and now grants recovery distance on its first aerial use; these changes give it high utility as a landing option against projectiles, recovery extender, combo starter, and counter against shields. While Shadow Ball has lost its charging hitbox, its travel pattern is less erratic, which makes it more accurate, and thus improves its zoning potential. When coupled with it having a much larger hitbox when fully charged, it is now one of Mewtwo's most reliable KOing options. Disable's stun duration has increased, while its hitbox has been extended and adjusted to reliably connect against even smaller fighters, while also being intangible, all of which improves its set-up potential. Its aerials have also generally improved, as they now have considerably less landing lag, are more consistent, and possess more utility. Its smash attacks have been similarly strengthened with larger hitboxes, improving their effectiveness. The improvements to Mewtwo's moveset also allow it to make better use of its Teleport-oriented mindgames.
However, Mewtwo has also received significant nerfs. Its infamous frailty was further exacerbated, thanks to its larger size and much lighter weight. Although still useful, Teleport's higher overall lag makes it less safe as an escape and mix-up option, whereas its added momentum can potentially lead to accidental self-destructs. The improved practicality of Mewtwo's moveset is also slightly offset by its overall nerfed frame data, which is especially evident in regard to its tail-based attacks. Despite being much more mobile, Mewtwo's approach is hindered by the weakening of dash-dancing and the removal of both wavedashing and moonwalking. Lastly, Mewtwo's grab game has been toned down: its pummel deals less damage, its back and up throws' KO potentials were considerably worsened because of their lowered knockback, and its down throw is now dependent on reads because of its increased ending lag and the removal of chain grabbing.
Overall, Mewtwo has been re-balanced to be a more practical, consistent, and traditional glass cannon that can rack up damage and KO much more easily. However, these traits come at the cost of it being even riskier and requiring even more precision because of its worsened endurance. Thanks to its buffs, Mewtwo has become drastically more successful and viable than in Melee.
Mewtwo has been buffed significantly via game updates. Some of its attacks have had their damage outputs increased, their lag decreased, and their hitboxes' sizes and durations increased, all of which improve its offense. Additionally, update 1.1.3 made Mewtwo considerably faster by increasing its walking and dashing speeds, which grant it a much more consistent offensive presence alongside its typically defensive presence. Mewtwo's dashing speed was increased even further in update 1.1.5, now being slightly faster than Sheik's. Said update also slightly increased Mewtwo's weight, which slightly improved its endurance.
Mewtwo also slightly benefits from the changes to shield mechanics brought about by updates 1.1.0 and 1.1.1: the universal increase to shieldstun allows Shadow Ball, some of its sweetspotted attacks and Confusion-reflected projectiles (such as Timber's tree, a fully charged Charge Shot or a fully charged Shadow Ball) to heavily damage a shield. Due to these aforementioned changes, Mewtwo is considered much more viable than it was upon its return to the series.

In competitive play
Tier placement and history
Mewtwo's return to the series was initially met positively, as players had soon noticed its increased mobility, power and range, which in turn led to it being perceived as a mid-tier character. However, players also lamented the nerfs to Mewtwo's already poor endurance. When coupled with other issues that became more prominent over the time, players gradually started to agree that Mewtwo's improved offense was not sufficient enough to compensate, in a case similar to Ike. While these drawbacks saw Mewtwo's perception plummet, some players insisted that Mewtwo was underrated and that critics were too focused on its frailty to see its positive traits. As time went on, Mewtwo received buffs via game updates, most notably to its mobility and aerials. These improvements led it to be ranked 37th on the first tier list, which established it as a low-tier character like in Melee.
After Mewtwo's dashing speed was further increased in update 1.1.5, players such as Abadango, Rich Brown and WaDi began placing higher with it in tournaments, and showed that its powerful offensive potential now outweighed its defensive shortcomings. This resulted in a drastic improvement in Mewtwo's perception within the community, which was reflected in it being ranked 10th on the second tier list. This new ranking was notable for not only reassessing it as a top-tier character but for also being the largest tier rise between the first and second tier lists. Mewtwo's continued success led to it being ranked 9th on the third tier list, which reaffirmed its status as a top-tier character.
Despite WaDi achieving some very notable results, such as placing 5th at Super Smash Con 2017 and 2GGC: MkLeo Saga, Mewtwo's tournament presence has slightly waned since then, owing to players becoming more capable of exploiting its weaknesses. This was further compounded by its best player, Abadango, picking up Bayonetta as a co-main and using her more often. Due to its slightly worsened perception and results, Mewtwo has dropped to 10th on the fourth and current tier list. Some smashers, however, like ZeRo and ANTi believe that it should be ranked slightly higher.
Mewtwo comes with matching character trophies, which are unlocked as usual. However, its alt. trophy will also be automatically granted upon booting up the version. Its existing non-fighter trophy remains in the game, completely unchanged; both it and the Classic trophy are simply labeled as "Mewtwo" in-game.
