Mewtwo (ミュウツー, Mewtwo) is a playable character in Super Smash Bros. Ultimate. It was confirmed on June 12th, 2018. Like in Melee, Mewtwo is once again an unlockable character. Mewtwo is classified as fighter #24.

Keiji Fujiwara's portayal of Mewtwo from Smash 4 was repurposed for Ultimate.

How to unlock[edit]

Complete one of the following:

  • Play VS. matches, with Mewtwo being the 60th character to be unlocked.
  • Clear Classic Mode with Fox or any character in his unlock tree, being the eighth character unlocked after Wolf.
  • Have Mewtwo join the player's party in World of Light.

With the exception of the third method, Mewtwo must then be defeated on Spear Pillar.


Mewtwo is overall a very polarizing character, not falling under one specific character archetype; despite being tall with a slew of powerful moves, Mewtwo is a lightweight fighter. Its overall mobility is among the best in the game, boasting among the fastest walking, dashing, and air speeds, along with average falling speed and gravity, which gives it a fairly good approach and a very potent neutral game.

Mewtwo's greatest strength is its air game. Its aforementioned high air speed, average falling speed and gravity allow it to maneuver in the air effectively, and has a very high double jump in order to punish high recoveries, as well as catch up to opponents who stall in the air. Another noteworthy aspect are its aerials; its neutral aerial has a variety of uses, as its very low ending lag gives it great combo potential into its other aerials, or Mewtwo can drag opponents down with it for grounded followups. Its forward and back aerials are very useful combo extenders and can KO at high percentages, with back aerial in particular covering a large area behind it, making it a potent edgeguarding tool. Up aerial, like back aerial, has large range, and is useful for juggling and has KO potential near the upper blast line. Lastly, its down aerial is a very powerful meteor smash when sweetspotted, and still has KO potential when sourspotted at high percents. However, it hits on frame 15, which makes it Mewtwo's slowest aerial when it comes to startup (although its startup overall is somewhat fast for a meteor smash, compounded with its high power).

Another one of Mewtwo's primary strengths is its potent grab game, being among the best in the game. While its grabs' speeds and ranges are only average, its throws well-rounded are very versatile. Forward throw, when all of its hits connect, becomes one of the most damaging throws in the game, giving it damage racking potential and ability to refresh its stale moves. Its up and back throws are among the strongest of their kind, with up throw being able to KO under 165% against any character, and back throw KOing under 100% at the ledge against most opponents. Lastly, its down throw is a useful mixup combo starter at higher percentages, and can also be used to read an opponent's reaction and capitalize on it. Overall, both its air game and grab game give Mewtwo a variety of options to quickly rack up damage on its opponents.

Mewtwo's varied attributes and special moves also give it among the best recoveries in the game. Its combination of a high air speed, a high double jump (the highest in the game), and average falling speed give it great offstage survivability, along with all four of its special moves providing a form of assistance with recovery; Shadow Ball's recoil can push Mewtwo back far enough to be a viable horizontal recovery option if facing away from the ledge, Confusion temporarily stalls it in the air, Teleport offers a long distance along with full intangibility and maneuverability, and Disable being able temporarily slow down Mewtwo's falling speed. With these options, Mewtwo has many options to mix up its recovery and allow it to safely get back onstage.

In comparison to its air and grab games, Mewtwo's ground game is more powerful, albeit riskier. While overall strong, all but a few of its grounded moves have noticeable ending lag, therefore makes them unsafe if shielded, whiffed, or dodged. One of its best ground moves is its neutral attack; it's a versatile move for many reasons, as it can both jab cancel and jab reset, which allows Mewtwo to start combos more consistently. Forward tilt is a good move for creating space at low-mid percentages, and can KO outright at high percentages near the ledge. Its up and down tilts are very reliable combo starters due to their long ranges and varying hitboxes, each having vertical knockback. Lastly, its smash attacks have distinct perks as well; its forward smash is powerful and can be angled, but is very punishable due to having noticeable startup and ending lag. Its up smash has low startup despite its range and power, and it functions as a great anti-air attack due to having a large disjoint that covers above Mewtwo. However, it has the highest amount of ending lag out of its smash attacks, making it very punishable. Lastly, down smash only hits on one side, but it has very high knockback scaling and has very low ending lag.

Lastly, Mewtwo has a versatile special moveset. Shadow Ball has many uses regardless of charge; it can stop approaches, has zoning potential, and is one of the strongest projectiles in the game when fully charged while doing respectably high shield damage, being able to KO at realistic percentages. Its side special, Confusion has impressive utility, as it can function as a command grab, a reflector, and even temporarily stall Mewtwo in the air, which can improve its recovery. Teleport grants intangibility and travels far with large horizontal momentum, which makes it a safe and versatile recovery option. The last of Mewtwo's special moves is Disable; as it grants intangibility on startup, it is very useful for punishing bad reactions and can secure KO confirms. However, it's risky to use otherwise because it has to be facing the opponent in order for it to work.

Despite Mewtwo's strengths, it has some noticeable weaknesses. One of which is its infamously poor endurance; Mewtwo's very light weight makes it easy to KO, while its tall frame, average falling speed and average gravity make it easier to combo compared to other characters of its weight class. Furthermore, Mewtwo lacks an effective aerial move to disrupt combos, and an attempt to Teleport out of a combo can be punished due to its noticeable ending lag and momentum.

The majority of Mewtwo's moveset also possesses some restrictions in spite of their advantages. Mewtwo's tail is only disjointed at its tip on attacks that utilize it, which makes its tail attacks susceptible to being countered. Fully charged Shadow Ball has recoil when used in the air. 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.

Mewtwo, while having a multitude of KOing options, often has trouble landing them. 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 and high ending lag. 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.

Overall, Mewtwo is a non-traditional glass cannon who falls under the category of the bait-and-punish archetype; Mewtwo must play cautiously and aware so the opponent doesn't capitalize on its tall hurtbox and light weight. However, this does not mean Mewtwo is forced to rely on turtling, 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. As a result, while Mewtwo's moveset may not be as versatile as other glass cannons such as Wolf, it makes up for instead having immense power and damage output.

Mewtwo's competitive potential is up for debate. Players like ESAM and Armada believe that Mewtwo should be ranked in the higher tiers due to its excellent mobility and damage racking game, while other smashers ZeRo and VoiD consider placing it in lower tiers due to its very large hurtbox and light weight, as well as its potent neutral being toned down slightly. Mewtwo itself has a very small playerbase, but the players who are dedicated to maining the character, like SDX have managed to get decent results.

Changes from Super Smash Bros. 4[edit]

Possibly due to its top tier status in the previous game, Mewtwo has been overall nerfed in its transition from Smash 4 to Ultimate. Arguably its biggest nerf is to the increase in its hitbox size; it has been readjusted at the tail to extend to near its tip, which significantly widens its hurtbox overall, especially in many animations that utilize it (like its back aerial and up aerial). Especially considering that Mewtwo is one of the lightest characters in the game, it has to be much more cautious and makes it much riskier to use its tail attacks, as even a decently strong attack can KO Mewtwo rather easily from a distance that other characters wouldn't get hit by.

Its potent neutral game has also been toned down; most importantly, down tilt has more ending lag, hindering its combo potential (although it is still a very versatile combo starter). Shadow Ball is slightly slower, making it less viable as a zoning and pressuring option from a distance, as well as doing less shield damage overall. Other potent moves in its neutral, such as its neutral aerial and forward aerial, have been nerfed; the former has heavily increased ending lag and a shorter duration with less hits, making it less viable as a long-lasting punishment tool, while the latter has increased startup and ending lag. It also launches at a slightly lower angle; while this makes it a better edgeguarding tool, this worsens its combo ability, especially into itself.

However, Mewtwo has received a multitude of buffs, although they don't completely compensate enough for the nerfs it has received. The first of which is its noticeably better and more consistent KO potential overall; moves like its neutral attack, forward tilt and dash attack deal more damage and knockback, now gaining KO potential at high percentages. Other attacks like forward smash has noticeably increased range, allowing it to secure KOs more easily from a wider range. The universally increased mobility and traction across the cast also benefits Mewtwo significantly, as now it can punish more easily out of shield and get around much more easily.

Despite the improvements made to Mewtwo's kill power, aesthetics and the benefits it received from Ultimate's mechanics, Mewtwo's nerfs outweigh its buffs and is considered to be less effective than its iteration in Smash 4. As such, Mewtwo has not made a significant impact in Ultimate's early metagame as its playerbase is very small. Abadango, WaDi, and Rich Brown, notable Mewtwo mains from SSB4, have dropped it in favor of other characters. Although Mewtwo has initially received favorable success from SDX in Ultimate's early metagame, he has since become inactive resulting in its results to have a significant decline. Due to this, Mewtwo's true viability has become a series of debate since many top players such as ZeRo believe that Mewtwo is low-mid tier at best while others such as Pandarian believe that it is one of the worst characters in the game. As of now, Mewtwo's true viability remains questionable.

  • Change Mewtwo's falling animation has been altered; it does not keep its arms folded, only doing so when falling forward or backwards.
  • Change Mewtwo's victory poses have been slightly altered:
    • The pose where Mewtwo laughs and floats has it float higher and look farther away from the screen.
    • The pose where Mewtwo thrusts its hand outward has an altered camera angle more towards its hand.
    • The pose where Mewtwo faces away from the screen has Mewtwo keep its eyes shut for slightly longer. [1]

  • Buff Mewtwo's air speed is higher (1.25 → 1.313).
  • Buff Mewtwo performs its double jump more quickly, improving its recovery and combo game.
  • Change Mewtwo's falling speed and fast falling speed are slightly faster (1.5 → 1.55) and (2.4 → 2.48) respectively. This improves its survivability but makes it more susceptible to combos.
    • Change As a result, its full hop is shorter (57 frames → 52 frames).

  • Nerf Backward roll has more ending lag (FAF 30 → 35).
  • Nerf The size of Mewtwo's tail hurtbox has been increased to near its tip. This reduces the disjoints of Mewtwo's attacks involving its tail, and gives it a bigger hurtbox overall.
  • Buff Air dodge grants more intangibility frames (frames 2-24 → 3-26).

Ground Moves[edit]

  • Neutral attack:
    • Change Jab 1 has an altered angle to keep opponents closer to Mewtwo (76°/70° → 361°/180°). This allows it to connect better with its infinite and jab reset, but removes its guaranteed jab cancel setups from Smash 4.
    • Buff Neutral infinite's finisher deals slightly more damage (2% → 2.5%) with no knockback compensation, now being able to KO at very high percentages at the ledge.
    • Buff Rapid jab comes out faster (frame 9 → 5).

    • Change Forward tilt always sends opponents in front of Mewtwo.
    • Buff Forward tilt deals more damage (10%/9%/8% → 11%/10%/9%) and knockback (20 base/100 scaling → 70/75), improving its safety on hit at lower percents while greatly increasing its KO potential.
    • Buff Forward tilt has larger hitboxes (4.3u/3.7u/2.9u → 5.0u/4.6u/4.2u) and altered placements (0.0u/1.8u/0.0u → 1.5u/2.5u/2.0u (X-offset), 0.0u/-2.0u/0.0u → 0.0u/0.0u/0.0u (Z-offset)), improving its range.
  • Up tilt:
    • Buff Up tilt deals more damage (6%/5%/4.5% → 7%/6%/5.5% (early), 5%/4%/3% → 6%/5%/4% (late), with knockback compensated on all but the early ID 3 hitbox (114/80 scaling → 105/71).
    • Change Up tilt's early ID 3 hitbox has increased knockback scaling (50 → 71), making it safer on hit at lower percents, but hindering its combo potential at higher percents.
    • Buff Up tilt's early tipper hitbox now launches at a vertical angle towards Mewtwo (361° → 110°), improving its combo potential.
    • Change Up tilt has a slightly altered animation.
  • Down tilt:
    • Nerf Down tilt has slightly more ending lag (FAF 21 → 24).
  • Dash attack:
    • Change Dash attack has an altered animation; Mewtwo lunges forward with one hand.
    • Change Dash attack launches at lower angles (60°/70°/80° → 54°/60°/70°).
    • Buff Dash attack's clean sweetspot and late sourspot deal more damage (10/4%% → 12%/4.5%) with their knockback not compensated, granting the clean sweetspot KO potential at realistic percentages, especially at the ledge with its lower launch angle.
  • Forward smash:
    • Buff Forward smash can be angled.
    • Buff Forward smash's sweetspot deals more damage (19% → 20%) and knockback (21 base/85 scaling → 30/90), significantly improving its KO potential.
    • Buff Forward smash's sweetspot is larger (5.6u → 6.3u), improving its range.
  • Up smash:
    • Change Up smash's energy swirl is opaque and stylized, instead of being a translucent whirl of particles.
    • Change Up smash hits 4 times instead of 7. However, its multi hits deal more damage (1% → 2%), making its total damage output unchanged.
    • Buff Up smash's initial hit sends at an autolink angle (100° → 368°), allowing it to connect better.
    • Nerf Up smash's final hit has less startup lag (frame 35 → 23). However, the move's total duration remains unchanged; coupled with the move's reduced hits, the move has significantly more ending lag overall (34 → 46 frames) and is less effective as an anti-air.
  • Down smash:
    • Buff Down smash deals more damage (15% → 16%) with no knockback compensation, improving its KO potential.
    • Buff Down smash has altered hitbox placements (3.5u/3.5u → 4.0u/4.0u (Y-offset)), slightly improving its vertical range.

Aerial Attacks[edit]

  • Buff All aerials have less landing lag (13 frames → 10 (neutral), 14 → 8 (forward), 17 → 10 (back), 13 → 8 (up), 18 → 11 (down)).
  • Neutral aerial:
    • Change Neutral aerial has altered visuals; rather than emitting multicolored orbs, Mewtwo discharges electricity around itself while flashing with a blue overlay.
    • Buff Neutral aerial's feet hitboxes send at an autolink angle (110° → 367°), and all of the multi hit hitboxes deal more set knockback (22/46 → 30/60), slightly improving its ability to connect into itself.
    • Nerf Neutral aerial's multi hit hitboxes are smaller (3.0u → 2.5u), reducing its range.
      • Buff However, the final hitbox is larger (10.9u → 13.5u).
    • Nerf Neutral aerial's final hit comes out much sooner (frame 40 → 28); this, combined with the move's increased duration (FAF 46 → 50), results in the move having significantly more ending lag overall (6 → 22 frames).
    • Change Neutral aerial hits fewer times (9 hits → 6), but deals the same damage, improving its damage consistency, but reducing its hitbox duration.
  • Forward aerial:
    • Buff Forward aerial's arm hitbox is larger (3.9u → 4.5u), giving the move more range.
    • Nerf Forward aerial has slightly more start-up lag (frame 6 → 7).
    • Nerf Forward aerial has more ending lag (FAF 38 → 40).
    • Nerf Forward aerial auto-cancels later (frame 36 → 37).
    • Change Forward aerial sends at a lower angle (50° → 47°), improving its KO potential but worsening its combo potential, especially into itself.
  • Back aerial:
    • Buff Back aerial's sweetspot has increased knockback scaling (90 → 97), improving its KO potential.
  • Up aerial
    • Change Up aerial has an altered animation; Mewtwo no longer faces the screen after finishing its tail sweep.
    • Buff Up aerial deals more damage (11%/10%/9% → 12%/11%/10%).
    • Nerf Up aerial has less knockback scaling (97 → 86), hindering its KO potential despite its increased damage output.
  • Down aerial:
    • Buff Down aerial's sweetspot's hitbox is positioned lower (-6.5u → -7.7u (Y-offset)), improving its vertical range.
    • Nerf Down aerial has more ending lag (FAF 46 → 48).

Throws/other attacks[edit]

  • Nerf Dash grab and pivot grab have slightly increased start-up lag (frame 9 → 10 (dash), frame 10 → frame 11 (pivot)), and all grabs have increased end lag (FAF 36 → 40 (standing), FAF 43 → 48 (dash), FAF 40 → 42 (pivot)).
  • Change Pummel has a darkness effect, instead of an electric effect.
  • Buff Forward throw's Shadow Balls send at a lower launch angle (43° → 38°), improving their KO potential at higher percents.
    • Change Back throw has an altered animation; Mewtwo tosses the opponent over its shoulder nonchalantly.

Special Moves[edit]

  • Shadow Ball:
    • Buff Shadow Ball reaches its full charge more quickly (138 → 123 frames).
    • Buff Shadow Ball, when combined with Mewtwo's faster mobility and changes to hitstun, has proper combo potential at various percentages depending on its charge.
    • Buff Fully charged Shadow Ball has reduced start-up (frame 23 → 18).
  • Confusion:
    • Buff Confusion has larger hitboxes (6.4u/9.2u → 7.4u/10.2u), improving its range.
    • Nerf Confusion no longer corrects the opponent's position to the center of the ripple, which may leave them too far away to follow up with an attack.
    • Nerf Confusion halts Mewtwo's horizontal momentum in the air, removing most of its utility as a recovery move and landing mixup.
  • Teleport:
    • Change Teleport has a darker, more distinct visual effect when Mewtwo disappears and reappears.
    • Buff Teleport has reduced landing lag (52 → 44 frames).
    • Buff Teleport can grab on to ledges more easily, with the new ledge grab range being roughly twice its original size.
    • Buff Teleport grants slightly more intangibility frames (frames 9-17 → 9-19).
  • Disable:
    • Buff Disable briefly grants intangibility on startup (frames 10-16).
    • Buff Disable travels farther, improving its horizontal range.
    • Nerf Disable's ground only hitbox is slightly smaller (2.34u → 2.3u), and it has altered hitbox placements (0.0u/0.0u/0.0u → -1.7u (Y-offset)/2.5u (Z-offset), giving it more difficulty hitting shorter characters, such as tiny characters or certain crouching characters.
    • Nerf Disable has more ending lag (FAF 47 → 52).
    • Change Disable has an altered animation; Mewtwo spreads its arms out without leaning forwards. The particle effect has also been changed to become a green flash of light that travels outwards at eye level, making its hitbox clearer.
  • Psystrike:
    • Change Mewtwo's Final Smash, Psystrike, has modified visual effects. The projectile is colored purple and white throughout the orb instead of purple at the edge and black/yellow/blue in the center. The center of the orb resembles a burst of energy instead of a vortex, and the move also causes more intense visual effects when it hits an opponent.
    • Buff Psystrike deals more damage (30% → 40%).

Update history[edit]

Mewtwo has been noticeably buffed via updates. In update 2.0.0, its recovery has become safer as Teleport grabs onto ledges much easier, which also reduces the risk of a self-destruct when attempting to directly teleport to the ledge. In update 3.0.0, its survivability has improved due to its increased weight, and some of its moves deal more damage and have more reach, which improves its already above-average damage racking game. Lastly, Shadow Ball deals more knockback, improving its already great KO potential. However, it is currently unknown how much these changes will affect Mewtwo's current tournament representation, as its playerbase is still very small.

Super Smash Bros. Ultimate 1.1.0

  • Nerf Disable has more ending lag (FAF 47 → 52).

Super Smash Bros. Ultimate 2.0.0

  • Nerf Dash attack has a lower shieldstun multiplier. (1.875x → 1.3x)
  • Change Forward tilt now always sends opponents in front of Mewtwo.
  • Buff Teleport can grab on to ledges more easily, with the new ledge grab range being roughly twice its original size.

Super Smash Bros. Ultimate 3.0.0

  • Change Mewtwo's weight has been increased (77 → 79). This slightly increases its survivability, but makes it slightly easier to combo.
  • Buff Neutral attack has less startup lag (frame 6 → 5).
  • Buff Forward tilt deals 1% more damage with knockback compensated.
  • Buff Up tilt deals 1% more damage with knockback compensated.
  • Buff Up tilt's tip hitbox has an altered angle that allows it to combo much better.
  • Buff Forward smash has more range.
  • Buff Up aerial deals 1% more damage with knockback compensated.
  • Buff Edge roll grants more intangibility.
  • Buff Edge attack has slightly more range.
  • Buff Shadow Ball deals more knockback.
  • Nerf Shadow Ball deals less shield damage.


Note: All numbers are listed as base damage, without the 1v1 multiplier.

  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 reset. The infinite's finisher also has decent knockback and can KO at very high percentages.
1% (loop), 2% (last)
Forward tilt   11% (near), 10% (mid), 9% (far) Spins, then 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%. It is also a decent KOing option at around 120% at the ledge.
Up tilt   7% (nearest), 6% (near), 5% (far), 4% (farthest), 5.5% (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. It has overall long range, as it can hit opponents near Mewtwo's back.
Down tilt Tail Sweep 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 and having low ending lag, 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. As a result, it can combo into an up tilt, a dashing up smash, neutral aerial, forward aerial, and up aerial.
Dash attack   12% (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 Shadow Blast 20% (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. Resembles its special move animation from Pokemon Stadium.
Up smash Galaxy Force 2% (hits 1-3), 10% (hit 4) Thrusts its arm upward to emit a swirling blast of dark energy. It functions very well as an anti-air attack due to the energy blast itself being a large disjoint that covers above Mewtwo's head, along with its multi-hit properties and long duration. Due to it hitting on frame 9, it is quite fast for a smash attack of its power, and has the lowest amount of start-up lag out of Mewtwo's smash attacks. However, its 46 frames of ending lag is the highest amount of out Mewtwo's smashes and in its moveset overall, which in turn makes it very punishable.
Down smash Shadow Bomb 16% Extends its arm at a diagonal angle toward the ground 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. While it has noticeable startup at frame 21, its ending lag relative to its power and startup is very low, being able to interupt after 22 frames. As such, it is safe on shield, and can be spammed rather safely. As a result, Mewtwo's down smash is one of its most viable KOing options.
Neutral aerial Body Spark 1.6% (hits 1-5), 4% (hit 6) Discharges electricity around itself. With only 7 frames of startup, it is tied with forward aerial for having the lowest startup out of Mewtwo's aerials. 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 during the attack. Its linking hits can also drag opponents down if fast-falling, which can lead to grounded follow-ups and even gimps.
Forward aerial Shadow Scratch 13% A dark energy-infused swipe. Due to it hitting on frame 7, it is tied with neutral aerial for having 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. Due to its very fast speed, versatility at a wide range of percentages (boasting combo and KO potential at low and high percentages, respectively), and decent range, it is a staple in Mewtwo's neutral game and moveset, and it is not uncommon for it to be considered one of the best forward aerials in the game.
Back aerial   13% (near), 11% (mid), 9% (far) Swings its tail behind itself 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. A powerful edgeguarding tool due to its aforementioned reach and having high knockback at its sweetspot.
Up aerial   12% (near), 11% (mid), 10% (far) Backflips to swing its tail in an overhead arcing motion, similarly to its up tilt. Its good knockback growth, large range and decent damage output makes it a viable juggling and KOing option. Despite its appearance, it is unable to hit opponents next to Mewtwo, unless during a fast-fall near the ground.
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 move. It is also a very 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. Its sourspot boasts respectable power and can KO at around 140% on grounded opponents.
Grab   Telekinetically holds an opponent. Mewtwo's overall grab range is average.
Pummel   2% Releases a pulse of darkness into the opponent. A fairly fast pummel.
Forward throw Shadow Cannon 3% (hit 1), 2% (Shadow Balls) Telekinetically lifts the opponent diagonally in the air before firing five Shadow Balls at them. It is one of the most damaging throws in the game when all hits connect, dealing 13%. 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, while opponents can also DI to avoid other incoming projectiles at higher percentages.
Back throw   10% Telekinetically throws the opponent backward. Posessing very high knockback, it is one of the strongest back throws in the game and one of Mewtwo's most viable KOing moves, KOing middleweights at around 95% near the ledge.
Up throw Psychic Whirlwind 12% Telekinetically whirls the opponent around itself before launching them upward above its head. This is the strongest up throw in the game, while being difficult to properly DI due to its purely vertical angle. It KOs middleweights at around 131% from ground level.
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 until very high percentages, though it can be used to punish an opponent's reaction or create 50/50 setups.
Floor attack (front)   7% Telekinetically spins around to swing its tail before getting up.
Floor attack (back)   7% Telekinetically spins around to swing its tail before getting up.
Floor attack (trip)   5% Performs a dark energy-infused swipe behind itself and then in front of itself while getting up.
Edge attack   7% Swings its tail in front of itself while climbing up.
Neutral special 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. Although its charge time is quite long, it possesses great KO potential when fully charged. 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. At low percentages, Shadow Ball can potentially act as a combo starter, notably into moves like dash attack or a dash grab.
Side special Confusion 1.15% (hits 1-7), 1% (throw), 1.4× (reflected projectiles) Swipes forward to emit a ripple of psychic energy from its hand. It has impressive utility, courtesy of it functioning as a reflector, a command grab, and even a potential 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, although it halts most of its horizontal momentum.
Up special 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. A great recovery move due to its aforementioned intangibility as well as travelling a long, safe distance.
Down special Disable 1% 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.
Final Smash Psystrike 40% 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. Incredible power, KOing at around 50% from center stage.

On-screen appearance[edit]

  • Emerges from a large mass of dark energy and then descends onto the ground.


  • Up Taunt: Closes its eyes and folds its arms as it telekinetically spins around on the spot while laughing ominously. Resembles the animation Mewtwo performs while using a physical move in the Pokémon Stadium games.
  • Side Taunt: Surrounds itself in a flame-like aura of dark energy, similarly to Lucario's up taunt.
  • Down Taunt: After turning to face the screen, it waves its hand in a circular motion in front of itself. It then proceeds to thrust its opposite arm forward while emitting a small spark of dark energy from its palm.

Idle poses[edit]

  • Crosses its arms and then moves them outward.
  • Holds out one hand in front of itself.

Victory poses[edit]

  • While radiating a dark aura, Mewtwo raises its left hand in front of itself while pulling back its right hand. Mewtwo then thrusts its right hand forward, emitting dark energy sparks from its palm. Mewtwo emits an ominous growl throughout the pose. In Japanese, it says 私は負けるわけにはいかない!, which translates to "I cannot afford to lose!"
  • Mewtwo crosses its arms as it turns its back to the screen, and looks back over its shoulder, scoffing. In Japanese, it says 私はなぜ ここにいるのか…?, which translates to "Why am I here?"
  • Does a single spin while levitating, then poses with a dark aura bursting from its body as it laughs. In Japanese, it says 愚かな!, which translates to "Foolish!"
A small excerpt of the title theme of Pokémon Red, Blue, Yellow, and Green Versions, a track which would go on to become the Pokémon main theme and the title theme for the entire series.

In competitive play[edit]

Notable players[edit]


Classic Mode: Psychic Control[edit]

Each round, through its psychic powers, Mewtwo controls previous opponents to use as teammates in future rounds; these teammates typically represent characters that have been possessed in their home series. Each round uses a track taken from the universe fought in the previous round.

Role in World of Light[edit]

Finding Mewtwo in World of Light

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

Mewtwo was present 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 being Whispy Woods).

Mewtwo's Fighter Spirit can be obtained by completing Classic Mode. It is also available periodically for purchase in the shop for 500 coins. Unlocking Mewtwo in World of Light allows the player to preview the first spirit below in the Spirit List under the name "???". As a Fighter Spirit, it cannot be used in Spirit Battles and is purely aesthetic. Each Fighter Spirit has an alternate version that replaces them with their artwork in Ultimate.

Additionally, one of Mewtwo's Mega Evolved forms appears as a Primary Spirit.

Character Showcase Video[edit]


  • Mewtwo's artwork for Ultimate resembles its artwork for Pokémon FireRed/LeafGreen, albeit with its hands and legs posed slightly differently.
  • Mewtwo was confirmed to be a playable character in Ultimate before Pikachu, making this the first time Pikachu was not the first Pokémon to be announced as part of the roster.
  • Mewtwo was the last non-DLC character added to the Super Smash Bros. Blog.
    • However, due to Mr. Game & Watch's blog page only being available on the Asian websites until December 7, Mr. Game & Watch was the last character added to the blog on non-Asian websites.
  • In Team Battles, there's a graphical glitch where if Mewtwo is with on a team composed of six or seven characters and is positioned the furthest behind the leading character on either the left or right side, the aura and energy effects will not appear.
  • Mewtwo is the only character who has its victory grunts/laughter omitted from the English Sound Test.
  • There's currently a positioning glitch when Mewtwo performs an air dodge when facing left. It will be facing away from the screen when disappearing and reappearing.
