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 portrayal of Mewtwo from Smash 4 was repurposed for Ultimate.

How to unlock

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 last character unlocked.
• 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.

Attributes

Mewtwo is overall a very polarizing character. It does not fall under one specific character archetype; despite being relatively large with a slew of powerful moves, Mewtwo is a lightweight fighter. Its overall mobility is among the best in the game, and it boasts among the fastest walking, dashing, and air speeds in the game, along with average falling speed and gravity, all of which give it a 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 it has a very high double jump to punish high recoveries, as well as to catch up to opponents who stall in the air. Also noteworthy are its aerial attacks; Body Spark, its neutral aerial, has a variety of uses, as its very low ending lag gives it great combo potential into its other aerials. It can also be used to allow Mewtwo to 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. Likewise, Shadow Claw's quickness and power make it one of Mewtwo's most reliable KO options against offstage opponents. Up aerial, like back aerial, has large range, 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, though it will send the opponent on a diagonally upward trajectory instead of downward. 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 of Mewtwo's primary strengths is its potent grab game, as its throws are among the best and most well-rounded out of the cast. Forward throw, when all of its hits connect, is one of the most damaging throws in the game, giving Mewtwo damage racking potential and the ability to conveniently refresh its stale moves. Its up and back throws are among the strongest of their kind; up throw is able to KO under 165% against any character, and back throw KO's 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. The only weakness in Mewtwo's grab game is its very average initial grab range, which can lead to whiffed grab attempts and counterattacks. Overall, though, both its air game and grab game give Mewtwo a variety of options to quickly rack up damage and KOs on its opponents.

Due to Mewtwo's varied attributes and special moves, its recovery potential is among the best 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. Teleport, its primary recovery move, covers a long distance and provides full intangibility and directional maneuverability, making Mewtwo exceedingly difficult to edgeguard. Furthermore, all three of its other special moves offer 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, and Disable temporarily slows Mewtwo's falling speed. With these options, Mewtwo has many ways to mix up its recovery and get safely back onstage.

In comparison to its air and grab games, Mewtwo's ground game is more powerful, albeit riskier. While strong in general, all but a few of its grounded moves have noticeable ending lag and are therefore unsafe if shielded, whiffed, or dodged. 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. Its dash attack has high knockback and KO potential at high percentages if it strikes point-blank, but is otherwise average. Lastly, its smash attacks have distinct perks as well; its forward smash is very powerful and can be angled, but is very punishable due to having noticeable startup and ending lag. It is more potent if the opponent is hit with the edge of the blast, and this can KO middleweights at around 70% near the edge of the stage. Its up smash has low startup despite its range and power, and it functions as a great anti-air attack due to a large disjoint and multiple hits that cover above Mewtwo. However, it has the highest ending lag of Mewtwo's smash attacks, making it very punishable. Lastly, down smash only hits in front of Mewtwo, but it has very high knockback scaling and 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, does respectably high shield damage, and is one of the strongest projectiles in the game when fully charged. 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. It can also be used in a pinch to escape pressure situations or to surprise an opponent with repositioning, though this is best done only on the ground, as Mewtwo will be left open when reappearing in the air. The last of Mewtwo's special moves is Disable, which stuns the opponent temporarily as if having suffered a shield break; the higher the opponent's damage, the longer the stun effect will last. As it grants intangibility on startup, Disable is very useful for punishing bad reactions and can secure KO confirms. However, it's risky to use otherwise because Mewtwo and the opponent must be facing each other and quite close in order for it to work, and its status as a projectile means that it can be reflected.

Despite Mewtwo's strengths, it has some noticeable weaknesses, the most glaring 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. While it has a multitude of KO options, it often has trouble landing them. Up and back throw can be risky to attempt because of Mewtwo's 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, Shadow Claw's 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 it with 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 ZeRo considers 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. However, after SDX's hiatus, Mewtwo's results have slightly declined.

Changes from Super Smash Bros. 4

During the commencement of Ultimate, Mewtwo was noticeably nerfed in its transition from Smash 4, but has also received notable buffs via patch updates.

Upon the initial release of SSBU, Mewtwo's tail hurtbox size was bigger compared to SSB4; this widened its hurtbox overall, especially in many animations that utilize the tail (like its back aerial and up aerial), while also worsening its spacing and defensive game. Considering that Mewtwo is one of the lightest characters in the game, it had to be much more cautious and made it riskier to use its tail attacks, as even a decently strong attack can KO Mewtwo rather easily at relatively low percentages. However, in a later update patch, Mewtwo's tail hurtbox was reduced to a much more manageable size, and is no longer as serious an issue for the character.

Its potent neutral game from Smash 4 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 and an option to catch air dodges, 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 for the nerfs it has received. The first 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, with all of them now gaining KO potential at high percentages. Other attacks like forward smash and up smash have noticeably increased range, allowing them 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 quicker. The problems with Mewtwo's previously extremely low traction has now been removed thanks to it being universally increased among the cast.

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 matter 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. However, it is at the very least widely agreed to be better than its Melee incarnation, with some players believing the character to have untapped potential. Additionally, the game updates have offered Mewtwo a plentiful of useful buffs, which has caused many top professionals to change their opinions on the character for the better.

Aesthetics

• Mewtwo has a more subdued color scheme and its body appears to have a glossy sheen. The end of its tail is also slightly larger.
• All attacks that utilize darkness have more intense particle effects.
• Mewtwo's idle pose has been altered; it now keeps one of its arms lifted.
• Mewtwo's falling animation has been altered; it does not keep its arms folded, only doing so when falling forward or backwards.
• 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]

Attributes

• Like all characters, Mewtwo's jumpsquat animation now takes 3 frames to complete (down from 5).
• Mewtwo runs faster (2.05 → 2.255).
  • Mewtwo's initial dash is significantly faster (1.4 → 2.255).
• Mewtwo walks slightly faster (1.2 → 1.26).
• Mewtwo's air speed is higher (1.25 → 1.313).
• Mewtwo performs its double jump more quickly, improving its recovery and combo game.
• 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.
  • As a result, its full hop is shorter (57 frames → 52 frames).
• Mewtwo is heavier (74 → 79), now the same weight as Kirby. This improves its survivability but makes it more susceptible to combos.
• Air dodge has more startup (2 frames → 3) and significantly increased ending lag, no longer being the fastest in the game(FAF 28 → 51).
• Backward roll has more ending lag (FAF 30 → 35).
• The size of Mewtwo's tail hurtbox has been slightly increased. This reduces the disjoints of Mewtwo's attacks involving its tail, and gives it a bigger hurtbox overall.
• Air dodge grants more intangibility frames (frames 2-24 → 3-26).

Ground Moves

• Neutral attack:
  • 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.
  • Rapid jab finisher deals slightly more damage (2% → 2.5%) with no knockback compensation, now being able to KO at very high percentages at the ledge.
  • Rapid jab comes out faster (frame 9 → 5).
  • Rapid jab's infinite hits have a reduced hitlag (1× → 0.5×) and SDI (1× → 0.4×) multiplier, making it harder to escape.
  • Rabid jab's finisher has had its large hitbox replaced with three smaller ones (7u → 5.5u/5.5u/5.5u), slightly improving its range.
  • Jab transitions into rapid jab slightly later (frame 11 → 12).
  • Rapid finisher has more ending lag (FAF 36 → 41).
  • Rapid jab's infinite hits have lost one of their hitboxes, with the other slightly increased to compensate (5.2u/5.2u → 5.6u).
  • Jab 1 and rabid jab's finisher have increased hitlag multipliers (1× → 1.8× (jab 1), 1× → 2× (finisher)).
• Forward tilt:
  • Forward tilt has a new animation; Mewtwo spins horizontally to strike with its tail.
  • Forward tilt always sends opponents in front of Mewtwo.
  • 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 improving its KO potential.
  • 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:
  • 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).
  • 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.
  • Up tilt's early tipper hitbox now launches at a vertical angle towards Mewtwo (361° → 110°), improving its combo potential.
  • Up tilt has a slightly altered animation.
• Down tilt:
  • Down tilt has slightly more ending lag (FAF 21 → 24).
• Dash attack:
  • Dash attack has an altered animation; Mewtwo lunges forward with one hand.
  • Dash attack launches at lower angles (60°/70°/80° → 54°/60°/70°). This hinders its combo potential depending on the hitbox, but grants it KO potential when combining the change below.
  • 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:
  • Forward smash can be angled.
  • Forward smash's sweetspot deals more damage (19% → 20%) and knockback (21 base/85 scaling → 30/90), significantly improving its KO potential.
  • Forward smash's sweetspot is larger (5.6u → 6.3u), improving its range.
• Up smash:
  • Up smash's energy swirl is opaque and stylized, instead of being a translucent whirl of particles.
  • Up smash hits 4 times instead of 7. However, its multi hits deal more damage (1% → 2%), making its total damage output unchanged.
  • Up smash's initial hit sends at an autolink angle (100° → 368°), allowing it to connect better.
  • 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:
  • Down smash deals more damage (15% → 16%) with no knockback compensation, improving its KO potential.
  • Down smash has altered hitbox placements (Y Offset: 3.5u/3.5u → 4.0u/4.0u), slightly improving its vertical range.
  • Down smash has less ending lag (FAF 44 → 41).

Aerial Attacks

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

Throws/other attacks

• 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)).
• Dash grab has less range (Z2 offset: 12.7u → 12u).
• Pivot grab has more range (Z2 Offset: -15.2u → -17.3u).
• Pummel has a darkness effect, instead of an electric effect.
• Forward throw:
  • Forward throw's Shadow Balls send at a lower launch angle (43° → 38°), making them connect more reliably.
  • Forward throw is no longer weight dependant, making the shots connect less reliably against lightweights and more reliably against heavyweights.
  • The increased hitlag makes the shots connect more reliably at lower percents, while the changes to knockback make the shots connect less reliably at higher percents.
• Back throw
  • Back throw has an altered animation; Mewtwo tosses the opponent over its shoulder nonchalantly.
  • Back throw deals more damage (10% → 11%) and has higher knockback scaling (75 → 79), now being almost exactly as strong as it was in Melee.

Special Moves

• Shadow Ball:
  • Shadow Ball reaches its full charge more quickly (138 → 123 frames).
  • Shadow Ball, when combined with Mewtwo's faster mobility, has proper combo potential at various percentages depending on its charge.
  • Fully charged Shadow Ball has reduced start-up (frame 23 → 18).
  • Fully charged Shadow Ball has more knockback scaling (67 → 71), improving its KO potential.
• Confusion:
  • Confusion has larger hitboxes (6.4u/9.2u → 7.4u/10.2u), improving its range.
  • Confusion now incapacitates opponents for very slightly longer as their percent increases. At high percentages, this is enough for true followups, however only into Mewtwo's faster attacks such as its neutral attack and tilt attacks.
  • 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. However, this may also leave the opponent far enough to be unable to punish Mewtwo with an aerial attack for using the move.
  • Confusion halts Mewtwo's horizontal momentum in the air, removing most of its utility as a recovery move and landing mixup.
• Teleport:
  • Teleport has a darker, more distinct visual effect when Mewtwo disappears and reappears.
  • Teleport has reduced landing lag (52 → 44 frames).
  • Teleport can grab on to ledges more easily, with the new ledge grab range being roughly twice its original size.
  • Teleport grants slightly more intangibility frames (frames 9-17 → 9-19).
• Disable:
  • Disable briefly grants intangibility on startup (frames 10-16).
  • Disable travels farther, improving its horizontal range.
  • 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.
  • Disable has more ending lag (FAF 47 → 52).
  • 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:
  • 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.
  • Psystrike deals more damage (30% → 40%).

Update history

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. Shadow Ball deals more knockback, improving its already great KO potential, though it is significantly less of a threat on shield. In update 4.0.0, its tail hurtbox was reduced slightly, making spacing with its tail attacks more effective, and some of its primary KO moves were improved as well. Confusion was also given slightly less startup. However, it is currently unknown how much these changes will affect Mewtwo's current tournament representation, as its playerbase is still very small.

1.1.0

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

2.0.0

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

3.0.0

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

4.0.0

• Mewtwo has a slightly shorter and thinner hurtbox on its tail.
• Up smash's final hit has a longer hitbox duration (2 frames → 4) and more knockback scaling (107 → 111).
• Down smash has less ending lag (FAF 44 → 41).
• Back throw deals more damage (10% → 11%) with no compensation on knockback.
• Confusion has less startup lag and reflects projectiles faster (frame 12 → 10), which results in a shorter total duration as well.

Moveset

• Mewtwo possesses a special jump. When jumping in midair, Mewtwo will ascend in a floatier, curved trajectory. The upward momentum of Mewtwo's double jump can be affected through various actions if timed correctly.
• Mewtwo can wall jump.

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 jab reset. The infinite's finisher also has decent knockback and can KO at very high percentages near the ledge.
			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. It is also a decent KOing option at around 120% near 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 send at favorable angles for comboing into itself, an up smash, neutral aerial, back aerial, or up aerial at low percentages. It can also be used for juggling beginning at medium percentages. It covers a very wide range, hitting opponents near Mewtwo's back, making it a reliable move for catching landings.
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 among Mewtwo's best combo starters, being able to combo into an up tilt, 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, which can KO at very high percentages. 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, and is an incredibly powerful punish out of a shield break or Disable, KOing at around 65% near the ledge uncharged, and even its sourspot has respectable power. Due to it hitting on frame 19 and having 31 frames of ending lag, however, it is very punishable when whiffed, though it is relatively safe on shield when spaced. It can be angled. It resembles Mewtwo's 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 boasting multi-hit properties and having a 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, it has the highest endlag out of Mewtwo's entire moveset at 46 frames, making 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 extremely low, as Mewtwo can act out of it after 41 frames. As such, it is safe on shield, and potentially even on whiff. It can also 2-frame punish at the ledge if timed correctly. As a result, Mewtwo's down smash is overall very versatile due to its safety and power, and serves as a great punishment out of a successful Disable or shield break.
Neutral aerial		Body Spark	1.6% (hits 1-5), 4% (hit 6)	Discharges electricity around itself with its limbs spread out. With only 7 frames of startup, it is tied with forward aerial for having the lowest startup lag 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 covers a very wide area and deals relatively high knockback, making it very potent at edgeguarding, particularly against midair jumps, and allows it to easily wall out opposing approaches. However, it has the second highest amount of start-up lag out of Mewtwo's aerial attacks at frame 13.
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 if used during a fast-fall near the ground (which can start combos at low percentages).
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. 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 grounded opponents at around 140%. Its moderately low landing lag combined with its diagonal angle also allows it to function as a low-percentage combo starter.
Grab			—	Telekinetically holds an opponent. Mewtwo's grab range and speed are 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 among 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			11%	Telekinetically throws the opponent backward. Its high damage and knockback makes it 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. As a result, it is extremely useful for KOing at high percentages if Mewtwo lands a grab, especially on stages with platforms. It KOs middleweights at around 131% from ground level, and at around 100% on Battlefield's top platform.
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.
Forward roll Back roll Spot dodge Air dodge		—	—
Techs		—	—
Floor attack (front) Floor getups (front)			7%	Telekinetically spins around to swing its tail before getting up.
Floor attack (back) Floor getups (back)			7%	Telekinetically spins around to swing its tail before getting up.
Floor attack (trip) Floor getups (trip)			5%	Performs a dark energy-infused swipe behind itself and then in front of itself while getting up.
Edge attack Edge getups			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 above-average shield damage and possesses transcendent priority, being able to break shields at half health or less. A fully charged Shadow Ball also deals recoil upon being fired; as a result, using it in midair will propel Mewtwo a moderate distance backward, which can help or hinder its recovery depending on which way it faces. Shadow Ball can potentially act as a combo starter at various percentages depending on its charge, notably into moves like dash attack, dash grab, and forward aerial.
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 at a frame disadvantage dependent on their damage, being able to combo into down tilt and forward aerial at high percents, with the latter being a KO setup. 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 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 grounded. If the opponent is in the air, they are slightly launched backward with set knockback, instead of being stunned, which will likely put them into a tech situation and potentially allow another opportunity to land the move. Useful at high percentages to guarantee a KO, but difficult to land. Due to being a projectile, Disable can also be reflected. Disable grants intangibility from frames 10 to 16, allowing it to beat out grounded maneuvers when timed properly, such as dash grabs.
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.

In competitive play

Mewtwo has not made an impact in Ultimate's metagame as its playerbase is very small. Most of Mewtwo's playerbase from Smash 4 have dropped the character 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. Many top players 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. However, it is at the very least widely agreed to be a lot better than its Melee incarnation.

Role in World of Light

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).

Spirits

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.
