—Introduction Tagline

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 Wii U and Super Smash Bros. for Nintendo 3DS on Club Nintendo by March 31st, 2015. Instead of retaining Masachika Ichimura as its voice actor, Mewtwo is now voiced by Keiji Fujiwara, who imitates some of Ichimura's voice clips from Melee.

Mewtwo is currently ranked 9th out of 58 on the current tier list, placing it in the A tier. This is a vast improvement from its low-tier placement in Melee, where it was ranked 21st out of 26. Mewtwo boasts excellent mobility: its dashing and air speeds are among the top 10 fastest of their respective attributes, it has a fast walking speed, and it can now wall jump. Its special moves each boast impressive utility: Shadow Ball is a projectile that is effective for zoning and KOing when uncharged and fully charged, respectively; Confusion is a reflector and command grab that grants a small vertical boost when used in midair; Teleport is a fast and unpredictable recovery option; and Disable is a potent set-up option, thanks to its stun effect.

Mewtwo also possesses a flexible combo game: its neutral attack's ability to quickly and reliably jab cancel makes it an invaluable set-up option for its grounded moves, whereas its down tilt is a very useful combo starter into its neutral, forward, and up aerials. Like in Melee, Mewtwo's grab game is also 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. Lastly, its smash attacks, forward aerial, and fully charged Shadow Ball are fearsome KOing options.

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. Lastly, Mewtwo has some difficulty KOing without proper reads or set-ups, as its strongest attacks can be difficult to land because of its aforementioned frame data issues.

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.

Attributes

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, which can make Mewtwo difficult for the opponent to track, and it 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, which 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, especially for a character of its size, and its 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 all have above average strength: forward smash is its most damaging smash and has the longest range, up smash is its fastest smash and functions as a powerful anti-air option, and down smash has the highest knockback scaling and 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 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, and 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 overall grab range being average at best. 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 Melee

Despite being considered one of the worst characters in Melee, Mewtwo initially received a mix of buffs and nerfs in SSB4. However, thanks to consistently receiving useful buffs via game updates, it has now been buffed significantly. Mewtwo's mobility is much better than in Melee: 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. 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 buffed to the point of being much more practical. Confusion, in particular, has drastically improved: it now functions as a traditional reflector, has considerably less ending lag, and now grants a slight vertical boost after its first use in the air. Shadow Ball's 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, 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. 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.

Aesthetics

• Mewtwo's design has changed. It has a smaller head, which is now mesaticephalic instead of dolichocephalic. It also has a narrower jawline, significantly larger digit pads, slightly more pronounced pinnae, and a slightly thicker tail. Additionally, Mewtwo's eye color is slightly subdued. Lastly, the aesthetic used in SSB4 has resulted in Mewtwo having a sleeker design, and the purple portion of its skin being slightly more vibrant. Altogether, these changes make Mewtwo appear virtually identical to its appearance in Pokédex 3D Pro.
• Mewtwo is less vocal, as it no longer uses a voice clip when using Confusion, Disable, and battering items.
• Mewtwo now has an on-screen appearance, an up taunt, and a down taunt.

Attributes

• Mewtwo is slightly taller. This improves its range, but makes its hurtbox slightly larger.
• Due to Mewtwo's model having an adjusted z-axis position, its hurtbox ends approximately at its digits, ankles, and the base of its tail. 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.
• Mewtwo is lighter (85 → 74), significantly hindering its endurance.
• Mewtwo walks faster (1.0 → 1.2).
• Mewtwo dashes faster (1.4 → 2.05).
• Mewtwo's air speed is faster (1.2 → 1.25).
• Mewtwo's fast falling speed is faster (2.3 → 2.4), improving its air game and making it less susceptible to juggling. When coupled with the updated air dodge mechanics, this also improves Mewtwo's landing options.
• Short hop, jump, and double jump are slightly higher, enabling its forward, back, and up aerials to auto-cancel with a short hop in spite of their later auto-cancel windows. Mewtwo can also now wall jump.
• Soft landing is faster (4 frames → 2).
• Crouch is lower.
• Walk and dash's animation have slightly changed. Mewtwo now hovers while facing the foreground at an angle, instead of being parallel to the ground.
• Double jump and tail-based attacks' sound clips are lower pitched.
• Techs' animations have changed. They are now more traditional, making it less susceptible to tech-chasing.
• Item swings' animations have changed. Dash swings also consist of one hit, instead of multiple hits.
• The removal of double jump canceling both helps and hinders Mewtwo. It improves its recovery, as it can now use aerials or its air dodge while retaining its momentum, but hinders its combo game.
• The weakening of dash-dancing and the removal of wavedashing and moonwalking significantly hinder Mewtwo's approach.

Ground attacks

• Neutral attack deals 2% less damage (6% → 4%). It also has decreased start-up (frame 8 → 6) and ending lag (frame 30 → 25). Altogether, these changes significantly improve its jab canceling potential. Neutral infinite has received a finisher, an upward swipe, and has decreased ending lag (frame 52 → 36). These changes improve its safety.
• Neutral infinite deals 1% less damage (2% → 1%).
• The weakening of SDI makes neutral infinite significantly more difficult to escape from.
• Sweetspotted dash attack deals 1% more damage (9% → 10%).
• Dash attack has increased knockback (80 (base)/60 (scaling) → 80/70 (clean), 40 (base)/60 (scaling) → 80/70 (late)). It has also received a disjointed hitbox near Mewtwo's hand. These changes improve its spacing potential.
• Dash attack's animation has slightly changed. Mewtwo now performs a dark-energy infused palm thrust with one hand, instead of both. This new animation re-positions its torso hitbox around Mewtwo's arms, but shortens its lingering hitbox's duration (frames 12-29 → 12-20).
• Mid and far forward tilt deal more damage (8% (mid)/5% (far) → 9%/8%) and have increased base knockback (10 (mid)/0 (far) → 20 (both)), improving their spacing potentials.
• Forward tilt has increased start-up (frame 6 → 10), ending lag (frame 29 → 36), and a shorter duration (frames 6-8 → 10-11).
• Up tilt deals less damage (10%/8%/6%/5% (clean/late) → 6%/5%/4.5%/4.5% (clean)/5%/4%/3% (late)), although its base knockback was somewhat compensated (0/70/70/0/60/60/50/40 → 70/60/50/50/60/50/40). These changes improve its combo potential.
• Up tilt has increased start-up (frame 6 → 8) and ending lag (frame 28 → 30).
• Down tilt deals less damage (9% (near)/8% (mid)/5% (far) → 5%/4.5%/4%), although its knockback was somewhat compensated (40 (base)/80 (scaling) (all) → 60/82 (near), 65/84 (mid), 60/70 (far)). Its angles have also been altered (80° → 80°/70°/60°). Altogether, these changes improve its combo potential and grant it spacing potential.
• Down tilt has increased start-up (frame 5 → 6), ending lag (frame 20 → 21), and a shorter duration (frames 5-7 → 6-7).
• Sweetspotted forward smash deals 1% less damage (20% → 19%).
• Sourspotted forward smash deals 4% more damage (12% → 16%).
• Forward smash has increased knockback scaling (75 (sweetspot)/80 (sourspot) → 85/90), a larger hitbox (2u → 3u), and has a longer duration (frames 19-20 → 19-21). Altogether, these changes improve its KO potential. Its sweetspot is also easier to land than its sourspot.
• Forward smash also has increased start-up lag (frame 18 → 19) and slightly decreased range.
• Up smash's first hit has increased weight-based knockback (40/18/18/8 → 90) and its second through sixth hits have larger hitboxes. These changes make its hits connect together better. It also has decreased ending lag (frame 70 → 69).
• Up smash's first hit has a slightly smaller hitbox.
• Up smash's last hit has altered knockback (40 (base)/118 (scaling) → 60/107). It also has slightly increased horizontal range, but slightly decreased vertical range.
• Down smash has increased knockback scaling (103 → 118), significantly improving its KO potential. It also has slightly increased range.
• Down smash has increased start-up (frame 20 → 21) and ending lag (frame 38 → 44).

Aerial attacks

• All aerials have decreased landing lag (26/13 frames → 13 (neutral), 25/12 frames → 14 (forward), 28/14 frames → 17 (back), 20/10 frames → 13 (up), 28/14 frames → 18 (down)). Due to the removal of L-canceling, however, they are not fully compensated.
• Neutral, forward, back, and up aerials auto-cancel later (frame 37> → 46> (neutral), frame 35> → 36> (forward), frame 30> → 38> (back), frame 33> → 36> (up)).
• Neutral aerial deals less damage (1%-2% (hits 1-8)/6% (hit 9) → 1%/4%) and its landing hitbox has been removed. It also has increased start-up lag (frame 5 → 7).
• Neutral aerial's first eight hits have increased weight-based knockback (20/20/40/40 → 22/22/46/46), their angles have been altered (160°/160°/110°/110° → 185°/185°/110°/110°), and they have been re-positioned from Mewtwo's torso to its hands and feet. Its last hit also has altered knockback (70 (base)/80 (scaling) → 40/110) and a larger hitbox. Altogether, these changes make its hits connect together better.
• Neutral aerial's visual effects have changed. The electricity now flashes green, yellow, blue, cyan, and violet at varying intervals, instead of flashing mauve and cyan at a consistent rate.
• The weakening of SDI makes neutral aerial significantly more difficult to escape from.
• Forward aerial deals 1% less damage (14% → 13%), hindering its KO potential. It also has a shorter duration (frames 6-9 → 6-8).
• Forward aerial's angle has been altered (84° → 50°). When coupled with its lower damage output, this improves its combo potential into itself.
• Forward aerial's animation has slightly changed. Mewtwo now swipes forward while lunging, instead of shifting its body in unison with the swipe. This new animation produces a less narrow hitbox with increased horizontal range, and results in its hitboxes being more disjointed from Mewtwo's arm.
• Neutral, forward, back, and up aerials have increased ending lag (frame 42 → 46 (neutral), frame 36 → 38 (forward), frame 32 → 40 (back), frame 35 → 40 (up)).
• Back aerial has a larger x-axis offset (5.1u → 5.5u), improving its horizontal range.
• Back aerial has increased start-up lag (frame 12 → 13).
• Near up aerial deals 1% more damage (10% → 11%) and has a longer duration (frames 10-13 → 10-14).
• Mid and far up aerials deal less damage (11% (mid)/14% (far) → 10%/9%) and have increased start-up lag (frame 9 → 10).
• Up aerial's sweetspot has been re-positioned from the tip of Mewtwo's tail to its base.
• Aerial sweetspotted down aerial deals 1% less damage (16% → 15%).
• Down aerial has decreased start-up (frame 18 → 15) and ending lag (frame 47 → 46). It also auto-cancels earlier (frame 45> → 42>). When coupled with Mewtwo's higher jump, this allows it to auto-cancel from a short hop.
• Down aerial's animation has slightly changed. Mewtwo now stomps in a more pronounced motion and has its foot infused with dark energy. This new animation results in its hitboxes being more disjointed from Mewtwo's foot, improving its range.
• The removal of meteor canceling significantly improves aerial sweetspotted down aerial's reliability.

Throws/other attacks

• Standing and dash grab have increased ending lag (frame 31 → 36 (standing), frame 41 → 43 (dash)). Dash grab also has increased start-up lag (frame 8 → 9).
• Pummel deals 1% less damage (3% → 2%).
• Pummel is faster (24 frames → 18).
• Forward throw's Shadow Balls are larger, but cover less distance.
• Back throw deals 1% less damage (11% → 10%) and has decreased knockback scaling (80 → 75), hindering its KO potential.
• Back throw's animation has slightly changed. Mewtwo now looks away while throwing the opponent, instead of looking at them.
• Up throw has decreased knockback (100 (base)/70 (scaling) → 72/65), significantly hindering its KO potential. However, it is still the strongest up throw in the game if directional influence is taken into account. It also has increased ending lag, slightly hindering its safety at low percentages.
• Down throw deals 2% less damage (11% → 9%).
• Down throw has an altered angle (69° → 74°).
• Down throw's animation has slightly changed. Mewtwo now somersaults to strike with its tail, instead of spinning its entire body to do so. This new animation transitions slightly faster, but has increased ending lag.
• The removal of chain grabbing hinders Mewtwo's grab game and damage racking ability.
• Floor attacks now have a normal effect, instead of an electric effect.
• Edge get-up and edge attack's animations have changed. They are now more traditional, making them significantly faster.

Special moves

• Fully charged Shadow Ball has decreased knockback (50 (base)/70 (scaling) → 30/67), hindering its KO potential. Shadow Ball's charge time has also increased, and it no longer has a hitbox while charging.
• Fully charged Shadow Ball has a larger hitbox and increased range.
• Grab now charge-cancels Shadow Ball, instead of immediately using it. It also no longer endures lag when it uses its shield to charge-cancel.
• Shadow Ball's movement pattern is significantly less erratic. This improves its accuracy, but makes it more predictable.
• Fully charged Shadow Ball causes significantly less recoil. This improves its safety while off-stage, but hinders its utility as a situational recovery option.
• Shadow Ball's visual effects have slightly changed. Saving a fully charged Shadow Ball now results in dark energy emanating from both of Mewtwo's hands, instead of one.
• The 19% damage increase to shields and the increase to shieldstun significantly improve fully charged Shadow Ball's shield pressuring potential.
• Due to consisting of nine small hitboxes instead of one large hitbox, Confusion deals ≈0.9505% less damage (10% → ≈9.0495%).
• Confusion now functions like a traditional reflector, as it changes reflected projectiles to Mewtwo's ownership and has a damage multiplier (1.4×). It also has decreased ending lag (frame 56 → 45).
• Aerial Confusion now grants a slight vertical boost after its first use, granting it recovery potential.
• Confusion's visual effects have changed. It now appears as a violet translucent ripple, instead of a white sparkle. Compared to the previous animation, it is almost identical to the animation Confusion used in Generations V and VI.
• Teleport grants a small amount of forward and/or backward momentum, but it plays out its momentum-based ending lag even if Mewtwo reappears on the ground. This slightly improves its recovery potential, but makes it slightly more punishable.
• Teleport has slightly increased start-up lag. This slightly improves its maneuverability, but makes it slightly more punishable.
• Teleport has decreased intangibility frames (frames 8-17 → 9-17).
• Disable has increased start-up (frame 15 → 16) and ending lag (frame 40 → 48). Additionally, it no longer affects a stunned opponent, instead of weakly launching them. Lastly, it now weakly launches an aerial opponent, instead of tumbling them.
• Disable's stun effect has a longer duration.
• Disable's animation and visual effects have slightly changed. Mewtwo now slightly tilts its head, instead of looking straight ahead. Its eyes also now turn green, instead of yellow.
• Mewtwo now has a Final Smash, Psystrike. Mewtwo undergoes Mega Evolution to become Mega Mewtwo Y and then immediately uses Psystrike, its signature move in the Pokémon games. Psystrike is a powerful sphere of psychic energy that can pass through walls and will powerfully launch any opponents it hits.

Update history

Mewtwo has been buffed significantly thanks to 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 light 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.

		Name	Damage	Description
Neutral attack			4%	Extends its arm to emit a pulse of dark energy. Repeatedly pressing the attack button causes Mewtwo to sway its arm up and down to emit multiple pulses of dark energy before finishing with a dark energy-infused upward swipe. The first hit can be jab canceled, with notable follow-ups including itself, up tilt, down tilt, a grab, forward smash, and forward aerial.
			1% (loop), 2% (last)
Forward tilt			10% (near), 9% (mid), 8% (far)	Swings its tail forward. It is Mewtwo's strongest tilt attack, has good range, and can be angled, all of which make it useful for spacing beginning at 40%. However, its low base knockback makes it unsuitable for KOing in spite of its near hitbox's decent damage output.
Up tilt			6% (nearest), 5% (near), 4% (far), 3% (farthest), 4.5% (farthest hitbox to opponents in front of Mewtwo)	Telekinetically backflips to swing its tail in an overhead arcing motion. Its near hitboxes' launching angles allows them to combo into themselves, an up smash, a back aerial, or an up aerial from 0% to low percentages. They can also be used for juggling beginning at medium percentages. In comparison, its far hitboxes can be used for spacing. It has overall long range, as it can hit opponents near Mewtwo's back.
Down tilt			5% (near), 4.5% (mid), 4% (far)	Crouches and spins around to swing its tail in front of itself. Due to it hitting on frame 6, it is Mewtwo's fastest tilt, which allows it to function as a good out of shield option. It is also Mewtwo's best combo starter and, like up tilt, has hitboxes that launch at different angles. As a result, it can combo into up tilt, a dashing up smash, neutral aerial, forward aerial, and up aerial.
Dash attack			10% (clean sweetspot), 9% (clean sourspot), 6% (late sweetspot), 4% (late sourspot)	A lunging, dark energy-infused palm thrust. Its clean sweetspot deals above average knockback. Depending on the hitbox it hits with and the opponent's damage, it can combo into neutral, forward, and up aerial. Its disjointed hitbox grants it impressive range for a dash attack, which makes it a decent punishment option at certain distances, and potentially difficult for the opponent to punish from a proper distance.
Forward smash			19% (blast), 16% (arms)	Quickly cups its hands to its side, and then thrusts them forward to perform a double palm thrust that emits a blast of dark energy. It is Mewtwo's most damaging smash attack, as even its sourspot has respectable power. Due to it hitting on frame 19 and having 31 frames of ending lag, however, its is very punishable. Its sweetspot KOs middleweights at 95% while near the edge of Final Destination in the Super Smash Bros. for Nintendo 3DS, and at 86% in Super Smash Bros. for Wii U. In comparison, its sourspot KOs them at 101% while near the edge of Final Destination in the 3DS version, and at 91% in the Wii U version.
Up smash			1% (hits 1-6), 10% (hit 7)	Thrusts its arm upward to emit a swirling, galaxy-shaped blast of dark energy. Due to it hitting on frame 9, it is quite fast for a smash attack, and has the lowest amount of start-up lag out of Mewtwo's smash attacks. It hits multiple times, which makes it a useful anti-air attack. However, its 33 frames of ending lag is the highest amount of out Mewtwo's smashes, which in turn makes it punishable. It can also miss small opponents, or opponents with very low crouches. Its last hit KOs aerial middleweights at 104% from anywhere on Final Destination in the 3DS version, and at 96% in the Wii U version.
Down smash			15%	Extends its arm at a diagonal angle to emit a blast of dark energy from its fingertip. It is one of the few down smashes that does not hit on both sides, but it is powerful nonetheless, and has the highest knockback scaling out of Mewtwo's entire moveset. It has 22 frames of ending lag, which is the lowest amount out of its smash attacks. Due to it hitting on frame 21, however, it has the highest amount of start-up lag out of Mewtwo's smashes. It KOs middleweights at 103% while near the edge of Final Destination in the 3DS version, and at 93% in the Wii U version.
Neutral aerial			1% (hits 1-8), 4% (hit 9)	Discharges electricity around itself. Its hitboxes are positioned at Mewtwo's hands and feet and keep the opponent trapped, whereas its last hitbox launches them. As a result, it is very useful for disrupting opponents, as Mewtwo has full control over its aerial movement even while using the move, allowing it to weave in and out to prevent approaches. However, it no longer has a landing hitbox like in Melee, which means that opponents can end up close to Mewtwo if the move ends early.
Forward aerial			13%	A dark energy-infused swipe. Due to it hitting on frame 6, it has the lowest amount of start-up lag out of Mewtwo's aerial attacks. When coupled with its respectable damage output and high knockback scaling, it is one of Mewtwo's most viable KOing options. It also boasts combo potential at low percentages, as it can also combo into itself, or be used as a follow-up from down tilt or neutral aerial. It KOs middleweights at 117% while near the edge of Final Destination in the 3DS version, and at 107% in the Wii U version. Despite its aforementioned dark energy visual effects, it has both darkness and slash effects.
Back aerial			13% (near), 11% (mid), 9% (far)	Swings its tail in an upward arc. It has a very large range, which makes it a decent gimping option when timed properly. Due to it hitting on frame 13, however, it has the second highest amount of start-up lag out of Mewtwo's aerial attacks. Its 17 frames of of landing lag is also the second highest amount out of its aerials. Its near hitbox KOs middleweights at 138% while near the edge of Final Destination in the 3DS version, and at 126% in the Wii U version.
Up aerial			11% (near), 10% (mid), 9% (far)	Backflips to swing its tail in an overhead arcing motion, similarly to its up tilt. Its 13 frames of landing lag is tied with neutral aerial's for the lowest amount out of Mewtwo's aerial attacks. Despite its appearance, it is unable to hit opponents next to Mewtwo. Its near hitbox KOs middleweights at 103% while near the upper blast line of Final Destination in the 3DS version, and at 95% in the Wii U version.
Down aerial			14% (grounded opponents, aerial sourspot), 15% (aerial sweetspot)	Backflips to perform a dark energy-infused stomp. It is Mewtwo's most damaging aerial attack. When coupled with its high knockback scaling, it is strong enough to KO grounded middleweights at 135% from anywhere on Final Destination in the 3DS version, and at 126% in the Wii U version. It is also a powerful meteor smash when sweetspotted in the air. Due to it hitting on frame 15, however, it has the highest amount of start-up lag out of Mewtwo's aerials. Despite its aforementioned dark energy visuals appearing right where Mewtwo stomps, it does not have a darkness effect.
Grab			—	Telekinetically holds an opponent. Mewtwo's overall grab range is average.
Pummel			2%	Electrocutes the opponent. A fairly fast pummel, however it is a little slower than other pummels of the same strength, making it somewhat weak overall.
Forward throw			3% (hit 1), 2% (Shadow Balls)	Telekinetically lifts the opponent diagonally in the air before firing five Shadow Balls at them. As of update 1.1.0, it is tied with Ganondorf and maximum Aura Lucario's forward throws as the most damaging forward throw in the game. However, the Shadow Balls can be reflected if the opponent wears a Franklin Badge, while other nearby opponents with reflectors and/or absorption moves can choose to intercept it.
Back throw			10%	Telekinetically throws the opponent backward. Despite having its damage output and knockback scaling lowered since Melee, it is one of the strongest back throws in the game. It KOs middleweights at 151% while near the edge of Final Destination in the 3DS version, and at 142% in the Wii U version.
Up throw			12%	Telekinetically spins the opponent around itself before launching them upward. Although its overall knockback has lowered considerably since Melee, it is the second strongest up throw in the game, surpassed only by Charizard's up throw as of update 1.0.8. Unlike Charizard's up throw, however, Mewtwo's is much less susceptible to directional influence, thanks to it launching at 90°. It KOs middleweights at 142% from anywhere on Final Destination in the 3DS version, and at 131% in the Wii U version.
Down throw			4% (hit 1), 5% (throw)	Telekinetically slams the opponent to the ground, and then somersaults in order to strike them with its tail. It has low knockback and somewhat high ending lag. As a result, it cannot properly combo into most of its moves, though it can be used to punish an opponent's reaction.
Forward roll Back roll Spot dodge Air dodge		—	—
Techs		—	—
Floor attack (front) Floor getups (front)			7%	Telekinetically spins around to swing its tail.
Floor attack (back) Floor getups (back)			7%	Telekinetically spins around to swing its tail.
Floor attack (trip) Floor getups (trip)			5%	Performs a dark energy-infused swipe behind itself and then in front of itself.
Edge attack Edge getups			7%	Swings its tail in front of itself while climbing up.
Neutral special	Default	Shadow Ball	2.5% (uncharged), 25% (fully charged)	Cups its hands to its side and creates a large, blackish violet sphere of dark energy between its hands, then thrusts its hands forward to launch the sphere. It can be fired immediately, which, when coupled with its erratic movement pattern, allows it to function as a pressuring option like Fireball. Conversely, it can be charge-canceled. While its charging time is quite long, a fully charged Shadow Ball is a viable KOing option, as it KOs middleweights at 91% while near the edge of Final Destination in the 3DS version, and at 82% in the Wii U version. A fully charged Shadow Ball also deals considerable shield damage and possesses transcendent priority, though it cannot break one with full health and can still cancel out certain projectiles. A fully charged Shadow Ball also deals recoil upon being fired; as a result, using it in midair will moderately propel Mewtwo backward, which can help or hinder its recovery.
	Custom 1	N/A

Side special	Default	Confusion	≈9.0495% (throw), 1.4× (reflected projectiles)	Swipes forward to emit a ripple of psychic energy from its hand. It has impressive utility, thanks to it functioning as a reflector, a command grab, and even a recovery option. As a grab, the ripple spins opponents around and leaves them tumbling downward, dropping them in front of Mewtwo and allows it to follow-up with other attacks. As a recovery option, its first use in midair gives Mewtwo a slight vertical boost.
	Custom 1	N/A
	Custom 2	N/A
Up special	Default	Teleport	—	Teleports to a different location. It is completely invulnerable during the move. It has less ending lag if Mewtwo Teleports directly back onto the ground, and it grants Mewtwo some horizontal momentum if ended in midair.
	Custom 1	N/A
	Custom 2	N/A
Down special	Default	Disable	1%	Kneels on one knee and emits a minuscule spark of psychic energy from its eyes toward the opponent, stunning them. It only works if the opponent is facing Mewtwo and making eye contact with it. If the opponent is in the air, they are slightly launched backward with set knockback, instead of being stunned. Useful at high percentages to guarantee a KO, but difficult to land. Due to being a projectile, Disable can also be reflected.
	Custom 1	N/A
	Custom 2	N/A
Final Smash		Psystrike	30%	Mega Evolves into Mega Mewtwo Y and performs Psystrike, its signature move in the Pokémon games. Psystrike is a powerful sphere of psychic energy that plows through both opponents and walls, and any opponent caught will be stunned before being launched by an intense, mind-shattering blow. It KOs middleweights at 38% while near the edge of Final Destination in the 3DS version.

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. 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, placing it in the F tier and, like in Melee, establishing it as a low-tier character.

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 and current tier list, which reaffirmed its status as a top-tier character. However, Mewtwo's popularity and results have fallen since then, due to people figuring out more its weaknesses, and has caused its players to achieve strong results significantly less often. This is further compunded by his best player, Abadango, picking up Bayonetta and using her more often. As such, Mewtwo is generally be thought to not be as good as it was initially deemed after its buffs, though it is still one of the two characters to have improved the most from their previous appearance, with the other being Mario.

Trophies

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.

Mewtwo

Mewtwo puts its psychic powers to great use in this game. Not only does it have floaty jumps, but its telekinesis gives its attacks extra reach and its throws added power. However, its light body makes it easy to launch, so if you're willing to take the risk of getting in close, it might just be worth it!

Mewtwo (Alt.)

Mewtwo's Confusion side special not only repels projectiles—it also reflects the damage back on your opponent. Its down special, Disable, stuns an enemy for longer the higher its damage is. Disable only works on foes that are facing Mewtwo.

Psystrike

Mewtwo's Final Smash starts as Mewtwo Mega Evolves into Mega Mewtwo Y. It then fires a huge psychic projectile that penetrates enemies and obstacles. This projectile doesn't do any damage, but it freezes every foe it hits in place. They can even be frozen midjump! Afterward, every foe hit with this projectile will take a powerful psychic hit to the head.

Mewtwo (non-fighter)

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 is the second of three Super Smash Bros. Melee characters to return to the series after being absent from Super Smash Bros. Brawl, succeeding Dr. Mario and preceding Roy.
• Mewtwo's pose in its official art for Super Smash Bros. 4 is nearly identical to its pose in its official art for Melee.
• As possible callbacks to Melee, Mewtwo has only one voice clip for when it is KO'd, and only the Japanese version of SSB4 features its victory quotes consisting of spoken dialogue.
• Mewtwo folds its arms in numerous instances, such as during its up tilt, up taunt, Hammer, helpless, losing/No Contest, and screen KO's animations, while asleep, and while teetering.
• Prior to update 1.0.7, it was possible to access glitched versions of Mewtwo's custom moves via a glitch involving shared Mii Fighters. Most of these crash the game, with the exception of both variations of Confusion, a non-functional version of Disable that renders Mewtwo helpless, and a version of Disable which zooms the camera in on Mewtwo and temporarily slows down time, all of which have limited functionality. It is unclear whether the glitch involved accessing custom moves that were incomplete, or data not intended for use of custom moves. One of the variations of Mewtwo's glitched custom Confusion is very similar to the soul breaker glitch. It is speculated that these were unfinished custom moves and that DLC characters were intended to have custom moves. While the glitch was removed by update 1.0.7, it was still possible to view replays containing these special moves prior to update 1.0.8.
• Mewtwo is the only veteran DLC character with a new voice actor, and the only character in SSB4 to speak only in the Japanese version.
• Mewtwo is the only DLC character to have been downloadable for free. It is also the only DLC character who does not share equipment types with any other DLC character.
• Mewtwo's non-fighter trophy model has very slightly different features from its playable character and fighter trophy's models. It has a slightly smaller head, slightly smaller eyes, a thicker and slightly longer tail, slightly smaller hands, a more vibrant shade of violet for its midsection, tail, and eyes, and its texture has a satin finish instead of a glossy finish. As a result, it resembles the Mewtwo from the first Pokémon movie, whereas Mewtwo's playable character and fighter trophy's models are virtually identical to its appearance in Pokédex 3D Pro.
• Mewtwo and Lucario are the only playable Pokémon in SSB4 who do not emerge from a Poké Ball as part of their on-screen appearances.
• Although Mewtwo's Final Smash involves Mega Evolution, it differs from Charizard and Lucario's in a few distinct ways. Mewtwo's is used for a single attack and renders it both invincible and stationary for its duration, whereas Charizard and Lucario's function as transformations that grant improved offense, mobility, and armor for their durations. Mewtwo's Final Smash is also referred to by its primary attack's name (Psystrike), instead of simply as "Mega Evolution".
