'''Mewtwo''' ({{ja|ミュウツー|Myūtsū}}, ''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''. ''Ultimate'' is noticeably the last game where Fujiwara voiced Mewtwo before passing away on April 12, 2020.

==How to unlock==
Complete one of the following:
*Play [[VS. match]]es, with Mewtwo being the 60th character to be unlocked.
*Clear {{SSBU|Classic Mode}} with {{SSBU|Fox}} or any character in his unlock tree, being the last character unlocked after {{SSBU|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]].

==Attributes==
Mewtwo is a zoner, and despite being relatively large with a slew of powerful moves, a [[weight|lightweight]] fighter. Its overall mobility is outstanding, and it boasts among the fastest [[walk|walking]], [[dash|dashing]], and [[air speed|air speeds]] in the game, along with average [[falling speed]] and [[gravity]]. 

Mewtwo has very high damage output on its grounded moves. Its [[neutral attack]] is a [[rapid jab]] that regularly racks up 20% or more damage if the opponent is caught at close range, but it is unsafe on shield. Its [[forward tilt]] has good range but noticeable startup, and a close hit with it can KO near the ledge at high percents. Its [[down tilt]] boasts relatively low ending [[lag]] and quick startup, while launching opponents at mostly vertical angles. This makes it a great combo tool, comboing into all of Mewtwo's aerials and up tilt. As with jab, however, it is not safe on shield. On the contrary, [[down smash]] is safe on shield. Nonetheless it is still a risky move to throw out in neutral. [[Up smash]] has the quickest startup of all Mewtwo's smash attacks and is a good anti-air, but also has the highest ending lag. [[Forward smash]] has decent range and is powerful when spaced, but is relatively slow and also not safe on shield. So although these moves are good if they hit, they're very punishable if they don't. This means that Mewtwo prefers not to play close to its opponent. It can, however, use its great ground speed to move in and punish mistakes using these moves.

Mewtwo's aerials are very good. [[Forward aerial]] is a safe poke, low percent combo starter and kill option. [[Neutral aerial]] is a multihit move, a combo starter at all percents, and also a safe poke when spaced. Both of these moves are fast and threatening, but they lack range. This makes Mewtwo's approach game with these moves significantly weaker against opponents that outrange it. [[Back aerial]] is slow and still gets beaten out by disjoints. It can't fulfill the role of giving Mewtwo good effective range in the neutral game, though it is useful for walling out offstage opponents who have poor range and/or recoveries. [[Down aerial]] has some startup but is a fairly strong [[meteor smash]] when sweetspotted.

Mewtwo's [[neutral special]], [[Shadow Ball]], has excellent versatility, as it can combo into virtually any of Mewtwo's quicker moves at any percent depending on the charge of the projectile. However, its function is not limited to combo starting; when fully charged, it becomes a reliable KO move at high percents. It also deals decent [[shield]] damage as well. In midair, it can even be used as a landing mixup, as the recoil from the fully charged variant pushes Mewtwo back a considerable distance. Mewtwo can utilise techs like [[wavebounce|wavebounces]], [[B-reverse|B-reverses]], Shadow Ball cancels and turnaround specials to make its movement even more tricky, improving its baits and punishes.

Mewtwo possesses a strong [[grab]] game. [[Up throw]] and [[back throw]] can both KO at reasonable percents, while [[forward throw]] is excellent at racking up damage. While [[down throw]] can't combo, it can force platform tech chases at specific percents. To counteract this, Mewtwo's grab range is poor, which can hurt the overall utility of its throws.

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 longevity. [[Teleport]], its primary recovery move, covers a long distance and provides full intangibility and directional manoeuvrability, making Mewtwo exceedingly difficult to [[edgeguard]]. Furthermore, two 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, and [[Confusion]] temporarily stalls it in the air and can turn Mewtwo around. With these options, Mewtwo has many ways to mix up its recovery and get safely back onstage, while being able to punish overzealous edgeguarders with its powerful and massive back aerial without losing recovery distance.

Lastly, Mewtwo has surprisingly good range for a lightweight fighter. All of its [[smash attack|smash attacks]] have [[disjointed]] hitboxes that allow them to beat out attacks safely (especially [[up smash]], as using it at the right time can prevent any [[stall-then-fall|stall-and-fall]] attack). [[Forward smash]] can be angled up or down to catch an airborne opponent or to edgeguard low recoveries, respectively. Its tail attacks also offer excellent range, despite not being as disjointed. Its back aerial in particular offers very large coverage behind Mewtwo and can be used in decently quick succession, making it a useful walling tool against opponents with low range attacks. Its tilts also use its tail, so they have good range as well. Tying into this is its aforementioned mobility; Mewtwo's extremely fast horizontal movement speed grants it a very potent punishment game with its range, allowing it to bait approaches and easily punish them with its long-reaching moves.

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, awkward 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. 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't pressure effectively, yet is also vulnerable to pressure.

Overall, Mewtwo is a non-traditional glass cannon who falls under the category of the zoner archetype; Mewtwo must play cautiously and aware so the opponent does not capitalise 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. Instead, Mewtwo should be played patiently, controlling space (zoning), baiting and poking with Shadow Ball, its aerials and its movement. As such, Mewtwo is a character with a fairly high learning curve, as it has to capitalise on reads more often than not because of its frailty and susceptibility to pressure. While Mewtwo's moveset may not be as versatile as other glass cannons such as {{SSBU|Wolf}}, it makes up for it with comparatively huge power and damage output. In short, Mewtwo has the attack power and range of an archetypal heavyweight character, but still retains the combo game and manoeuvrability of a lightweight character.

Mewtwo's competitive potential is up for debate. Players like {{Sm|ESAM}} and {{Sm|Armada}} believe that Mewtwo should be ranked as a high-mid tier character due to its excellent mobility and damage racking game, while other players consider placing it as a low-tier due to its large hurtbox and light weight, as well as its potent neutral being toned down slightly. Mewtwo itself has a small playerbase, but the players who are dedicated to maining the character, like {{Sm|SDX}} have managed to get decent placements. However, as SDX has recently dropped the character, its representation in tournaments have undergone a significant decline, with its results still remaining minimal.

==Changes from ''[[Super Smash Bros. 4]]''==
In the late metagame of ''[[SSB4]]'', Mewtwo ranked as a top-tier character (10th out of 55 characters), thanks to a combination of a powerful neutral game, excellent mobility, a powerful projectile, and a dangerous combo game. Mewtwo has received a large mix of buffs and nerfs in its transition to ''Ultimate'', but was noticeably nerfed overall.

Mewtwo's largest nerf was to its hurtbox. Mewtwo's tail hurtboxes' sizes were considerably increased, which widened its hurtbox overall. Considering Mewtwo is already one of the lightest characters in the game, this forces Mewtwo to be much more cautious with using its tail attacks, as trading with even a decently strong attack can prove fatal. Additionally, this now causes Mewtwo to be usually clipped by attacks during some situations (such as when turning around). Overall, these changes worsen both its spacing and defensive game.

On top of this, Mewtwo also received many nerfs to its best moves, hindering both its previously strong [[neutral game]] and combo ability. [[Shadow Ball]] now deals negative shield damage, making it less viable as a zoning and pressuring option from a distance. [[Neutral attack]], as with most others, can no longer effectively [[jab cancel]], removing its wide range of previously true followups. [[Down tilt]] has more endlag, which combined with the changes to knockback, impairs its combo potential and narrows Mewtwo's KO setups. [[Neutral aerial]] has heavily increased ending lag, a shorter duration, and smaller hitboxes, making it less viable for covering options and removing its aerial combo potential, limiting Mewtwo to land with the move and read the opponent's trajectory accordingly. [[Forward aerial]] is slightly slower and launches at a slightly lower angle, worsening its combo ability into itself and almost completely removing its ability to initiate a deadly [[wall of pain]] at low to mid percentages.

The changes to [[air dodge|air dodging]] in ''Ultimate'' have also hindered Mewtwo moreso than any other character. Since air dodges can now only be utilized once before landing or getting hit, combined with them generally having more ending lag, this especially affects Mewtwo as it previously held the distinction of having the air dodge with the lowest ending lag out of the entire roster (allowing it to be spammed rather safely to play mindgames), which renders it even more susceptible to combos and juggling, given its large hurtbox for its weight class.

However, Mewtwo has received a multitude of buffs in the transition as well. Mewtwo's KO potential is considerably better and more consistent 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, such as [[Disable]] and its [[smash attacks]], have noticeably increased range, allowing them to secure KOs more easily from deceptive ranges. Shadow Ball has also received a slight increase in knockback when fully charged, making it an even more viable KOing option. Mewtwo has also seen slight improvements to its survivability, thanks to its heavier weight and faster falling speed, although it remains a rather easy character to KO.

Most of the universal changes to gameplay mechanics have also benefitted Mewtwo. Although the changes to air dodging mostly hamper it, they has also made its edgeguarding game more potent, thanks to its quick air speed, large variety of aerial attacks, useful projectile, long double jump and powerful recovery. The universal increase in mobility and traction across the cast, the reintroduction of [[dash-dancing]], and the ability to [[dash-canceling|use any attack out of a run]], also benefits Mewtwo, as it can now get around much quicker, ocasionally play mindgames on its approach, and punish more easily both in the neutral game and [[out of shield]]. Finally, the reductions to landing lag improve Mewtwo's safety on hit, opening some new combo routes due to its streamlined [[jumpsquat]].

In the end, Mewtwo is considered to be notably less effective than its ''SSB4'' iteration, as despite the improvements made to its mobility, survivability, kill power, and the benefits it received from ''Ultimate''{{'}}s mechanics, these changes do not completely compensate for the considerable nerfs it has received to its defensive game, combo ability, and hurtbox. As a result, Mewtwo has not made a significant impact in Ultimate's early metagame, as its playerbase is very small; players such as {{Sm|Abadango}}, {{Sm|WaDi}} and {{Sm|Rich Brown}} have dropped Mewtwo in favor of other characters, and although it initially received favorable success from {{Sm|Secret}} in ''Ultimate'''s early metagame, he has since dropped it in favor of {{SSBU|Joker}}, resulting in Mewtwo's results to have a significant decline. Due to this, many top players now consider it a lower-mid or low tier character, and a few others even believe it to be one of the worst characters in the game. However, game updates have offered Mewtwo bountiful buffs that have either helped alleviate some of its issues, improved its strengths, or fix a few inconsistencies; this has caused some professionals to reassess their opinions on the character, with some believing it to have untapped potential and to be viable. As of now, Mewtwo's true viability in competitive play remains debatable.

==Update history==
Mewtwo has received a mixture of buffs and nerfs, but has been noticeably buffed overall. In update 2.0.0, its recovery became safer as [[Teleport]] grabs edges more reliably, which also reduces the risk of a self-destruct when attempting to directly Teleport to the edge. In update 3.0.0, Mewtwo's endurance was improved due to its increased weight, and some of its moves deal more damage and gained more range. This same update also increased [[Shadow Ball]]'s knockback, but made it significantly less of a threat on shield. In update 4.0.0, Mewtwo's tail hurtbox was shrunken slightly, which made spacing with its tail attacks more effective. Additionally, some of its primary KO moves were improved, while [[Confusion]] was given slightly less start-up. 

Update 7.0.0 buffed Mewtwo once again, although not to the same extent as 4.0.0. Mewtwo's shield was increased, and its posture was altered while shielding, making it less likely for it to be shield poked. Additionally, Mewtwo's down tilt now reaches further into the plane of gameplay on frame 6 of its hitbox, preventing it from missing some characters entirely in certain situations. 

As a result, Mewtwo fares better compared to release.

{{MovesetTable
|game=SSBU
|neutralcount=1
|neutralinf=y
|neutralname=&nbsp;
|neutral1dmg=4%
|neutralinfdmg=1% (loop), 2% (last)
|neutraldesc=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.
|ftiltname=&nbsp;
|ftiltdmg=11% (near), 10% (mid), 9% (far)
|ftiltdesc=Mewtwo spins, then swings its tail forward. It is surprisingly strong, KOing at around 90% near the ledge, while the sourspots don't even KO much later. It can be angled as well. When angled up it can function as an anti air, and when angled down it can hit opponents hanging on the ledge. Its long range can allow it to function as a whiff punish tool.
|utiltname=&nbsp;
|utiltdmg=7% (nearest), 6% (near), 5% (far), 4% (farthest), 5.5% (farthest hitbox to opponents in front of Mewtwo)
|utiltdesc=Telekinetically backflips to swing its tail in an overhead arcing motion. Its hitboxes launch opponents 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. Most of Mewtwo's tail is a hurtbox, however, so it is less useful as an anti-air against other characters with disjointed hitboxes that can beat it out.
|dtiltname=&nbsp; Tail Sweep
|dtiltdmg=5% (near), 4.5% (mid), 4% (far)
|dtiltdesc=Crouches and spins around to swing its tail in front of itself. It's Mewtwo's fastest tilt and has relatively low endlag making it good for close quarters combat. It is also among Mewtwo's best combo starters, being able to combo into an up tilt, or any of Mewtwo's aerials. However, the sourspot on the tip of the tail does not lead to any combos, making it only useful for poking in the neutral. 
|dashname=&nbsp;
|dashdmg=12% (clean sweetspot), 9% (clean sourspot), 6% (late sweetspot), 4% (late sourspot)
|dashdesc=A lunging, dark energy-infused palm thrust. Its clean sweetspot deals above average knockback, which can KO at very high percentages (starting at around 140% at the ledge). It's relatively fast and covers good distance making it good for whiff punishes. However, it is not safe to use it too much. The late hit can lead into a buffered forward aerial at very low percentages.
|fsmashname= Shadow Blast
|fsmashdmg={{ChargedSmashDmgSSB4|20}} (blast), {{ChargedSmashDmgSSB4|16}} (arms)
|fsmashdesc=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 70% 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 or shielded at close range. It can be angled.
|usmashname= Galaxy Force
|usmashdmg={{ChargedSmashDmgSSB4|2}} (hits 1-3), {{ChargedSmashDmgSSB4|10}} (hit 4)
|usmashdesc=Thrusts its arm upward to emit a swirling blast of dark energy. It's fast coming out at frame 9. But the initial, 'scooping' hitbox is very small and opponents can fall out of it very easily. This makes it unreliable as an out of shield punish. The large, disjointed and long lasting hitbox above Mewtwo can work as an anti air. But due to the high endlag, if this move whiffs it will be very easy for the opponent to punish. 
|dsmashname= Shadow Bomb
|dsmashdmg={{ChargedSmashDmgSSB4|16}}
|dsmashdesc=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. 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 also has a somewhat generous 2-frame punish window at the ledge. It can also serve as a great punish out of a shield break or Disable, as it does not have a sourspots compared to the similar forward smash.
|nairname= Body Spark
|nairdmg={{ShortHopDmgSSBU|1.6}} (hits 1-5), {{ShortHopDmgSSBU|4}} (hit 6)
|nairdesc=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. Its fast startup and long duration make it great for catching jumps. In addition, it is Mewtwo's best out-of-shield option, hitting both sides of mewtwo. Its linking hits can also drag opponents down if fast-falling, which can lead to follow-ups, gimps and kill confirms, most reliably into up smash.
|fairname=Shadow Scratch
|fairdmg={{ShortHopDmgSSBU|13}}
|fairdesc=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. It is one of Mewtwo's best KO options. It also boasts combo potential at low percentages, as it can also combo into itself, down tilt, Shadow Ball and more. It is a very safe poking option because of its range, safety on shield and low landing lag. However it is susceptible to anti airs as it is not disjointed. It can also be used as an edgeguarding tool, albeit with some difficulty due to the hitbox.
Its speed, safety, utility at all percentages and range make it a staple in Mewtwo's neutral game and moveset, and it is not uncommon for it to be considered one of the best, if not ''the'' best forward aerial in the game.
|bairname=&nbsp;
|bairdmg={{ShortHopDmgSSBU|13}} (near), {{ShortHopDmgSSBU|11}} (mid), {{ShortHopDmgSSBU|9}} (far)
|bairdesc=Swings its tail behind itself in an upward arc. It covers a very wide area and deals relatively high knockback, making it great at edgeguarding, particularly against double jumps, and allows it to easily wall out opposing aerial approaches. However, it has the second highest amount of start-up lag out of Mewtwo's aerial attacks at frame 13. Additionally, disjointed attacks like swords will beat out its hitbox, reducing its utility against some characters.
|uairname=&nbsp;
|uairdmg={{ShortHopDmgSSBU|12}} (near), {{ShortHopDmgSSBU|11}} (mid), {{ShortHopDmgSSBU|10}} (far)
|uairdesc=Backflips to swing its tail in an overhead arcing motion, similarly to its up tilt. It has a lot of range making it great for juggling, and can KO at around 120% near the upper blast line. It can be used to catch high recoveries and jumps onto the stage. If used when landing, it can combo into all of Mewtwo's aerials and Shadow Ball, potentially leading to KOs. Most notably, a rising double jump up aerial can lead into a forward aerial as a reliable KO confirm. However, it is difficult to hit short opponents when landing with the move.
|dairname=&nbsp;
|dairdmg={{ShortHopDmgSSBU|14}} (grounded opponents, aerial sourspot), {{ShortHopDmgSSBU|15}} (aerial sweetspot)
|dairdesc=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, making it a good edgeguarding tool. 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 combo into tilts at low percents, and aerials at higher percents. 
|grabname=&nbsp; 
|grabdesc=Telekinetically holds an opponent. Mewtwo's grab range and speed are average.
|pummelname=&nbsp;
|pummeldmg=1.5%
|pummeldesc=Releases a pulse of darkness into the opponent.
|fthrowname=Shadow Cannon
|fthrowdmg=3% (hit 1), 2% (Shadow Balls)
|fthrowdesc=Telekinetically lifts the opponent diagonally in the air before firing five [[Shadow Ball]]s 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.
|bthrowname=&nbsp;
|bthrowdmg=11%
|bthrowdesc=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 100% near the ledge.
|uthrowname=Psychic Whirlwind
|uthrowdmg=12%
|uthrowdesc=Telekinetically whirls the opponent around itself before launching them upward above its head. One of the strongest up throws in the game, KOing middleweights at around 140% from ground level, and even earlier when standing on a platform.
|dthrowname=&nbsp;
|dthrowdmg=4% (hit 1), 5% (throw)
|dthrowdesc=Telekinetically slams the opponent to the ground, and then somersaults in order to strike them with its tail. It is very easy to DI and has very little hitstun, so it can't combo into anything. However, at mid to high percents it can force the opponent to tech on a platform if used below one, potentially leading to a Disable.
|floorfname=&nbsp;
|floorfdmg=7%
|floorfdesc=Telekinetically spins around to swing its tail before getting up.
|floorbname=&nbsp;
|floorbdmg=7%
|floorbdesc=Telekinetically spins around to swing its tail before getting up.
|floortname=&nbsp;
|floortdmg=5%
|floortdesc=Performs a dark energy-infused swipe behind itself and then in front of itself while getting up.
|edgename=&nbsp;
|edgedmg=7%
|edgedesc=Swings its tail in front of itself while climbing up. It has great range for a ledge attack, second only to bowser.
|nsname=Shadow Ball
|nsdmg=2.5% (uncharged), 25% (fully charged)
|nsdesc=Cups its hands to its side and [[bulbapedia:Shadow Ball (move)|creates a large, blackish violet sphere of dark energy]] between its hands, then thrusts its hands forward to launch the sphere. Depending on the charge and the opponent's percent, Shadow Ball can combo into almost any move, including, but not limited to, down tilt, up tilt, grab, forward aerial and dash attack. It can be b-reversed and wavebounced, giving Mewtwo tricky movement mixups to use in all areas of play (e.g. neutral, landing, etc.). Like all of Mewtwo's specials, it can be used to cancel the upward momentum of Mewtwo's double jump. When fully charged, Shadow Ball travels faster, is harder to clank with and can KO at mid-high percents. Because of these attributes, it is one of Mewtwo's best tools in the neutral game.
|ssname=Confusion
|ssdmg=1.15% (hits 1-7), 1% (throw), 1.4× (reflected projectiles)
|ssdesc=Swipes forward to [[bulbapedia:Confusion (move)|emit a ripple of psychic energy]] from its hand. It has impressive utility, courtesy of it functioning as a [[reflector]], a [[Grab#Special_moves_that_can_grab|command grab]] and even as an option when landing, recovering or getting up from the ledge. As a grab, the ripple spins opponents around and leaves them [[tumbling]] at a frame disadvantage dependent on their damage. If used in the air at 140%, it can combo into forward aerial, almost always leading to a KO. It functions as a [[Fall Break]], making it useful for mixing up landings and recovery timings. 
|usname=Teleport
|usdmg=—
|usdesc=[[bulbapedia:Teleport (move)|Teleports]] to a different location. It is completely invulnerable after frame 9. It has lots of landing lag if Mewtwo Teleports directly back onto the ground, and it grants Mewtwo very limited horizontal momentum if ended in midair. A great recovery move due to its aforementioned intangibility as well as travelling a long distance. It can also function as a landing mixup, despite the high landing lag.
|dsname=Disable
|dsdmg=1%
|dsdesc=[[bulbapedia:Disable (move)|Emits a minuscule spark of psychic energy]] from its eyes toward the opponent, [[stun]]ning 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. It is 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 attacks when timed properly.
|fsname=Psystrike
|fsdmg=40%
|fsdesc=[[bulbapedia:Mega Evolution|Mega Evolves]] into Mega Mewtwo Y and performs [[bulbapedia:Psystrike (move)|Psystrike]], its {{s|bulbapedia|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.

*'''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. If Mewtwo is holding an item, the item will orbit telekinetically around its body as it does this.

===[[Victory pose]]s===
*'''Left:''' 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 "{{ja|私は負けるわけにはいかない！|Watashi wa makeru wake ni wa ikanai!}}", which translates to "I cannot afford to lose!"
*'''Up:''' Mewtwo crosses its arms as it turns its back to the screen, and looks back over its shoulder, scoffing. In Japanese, it says "{{ja|私はなぜ ここにいるのか…？|Watashi wa naze koko ni iru no ka...?}}", which translates to "Why am I here...?"
*'''Right:''' Does a single spin while levitating, then poses with a dark aura bursting from its body as it laughs. In Japanese, it says "{{ja|愚かな！|Orokana!}}", which translates to "Foolish!"

==In competitive play==
As a result of its nerfs from ''[[Smash 4]]'', Mewtwo has not made an impact in ''Ultimate''{{'}}s metagame. Most of Mewtwo's playerbase from ''Smash 4'' have dropped the character in favor of other characters, leaving it to have a below average representation. Although Mewtwo has initially received favorable success from SDX, he has since dropped the character. 

Game updates slightly addressed some of Mewtwo's biggest flaws, allowing it to gain more attention in the eyes of some players. While Mewtwo is still widely considered to be a low-to-mid tier character, the buffs, as well as decent regional placements by players such as {{Sm|Zenkai}} and {{Sm|????}}, has led some people to believe that the character has untapped potential. However, this is currently debatable, because Mewtwo's playerbase and results remain small in spite of its perception.

===Notable players===
<!--If you are planning to add a player you consider to be notable, please provide tournament results in some shape or form in the edit summary (be it a link to a results thread or bracket of placing high in a tournament of other notable players or a video of them beating a notable player). Winning tournaments without notable players present is generally not enough to warrant a spot.-->

==Role in [[World of Light]]==
[[File:WoL-24Mewtwo.jpg|thumb|Finding Mewtwo in World of Light|left]]
Mewtwo was among the fighters that were summoned to fight the army of [[Master Hand]]s.

Mewtwo was present when [[Galeem]] unleashed his beams of light. Mewtwo and {{SSBU|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 {{SSBU|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).

==[[Spirit]]s==
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.

==Trivia==
*Mewtwo's artwork for ''Ultimate'' resembles its [[bulbapedia:File:150Mewtwo.png|artwork]] for [[bulbapedia:Pok%C3%A9mon FireRed and LeafGreen Versions|''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 (SSBU)|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.
*Mewtwo is the only character who has its victory grunts/laughter omitted from the English Sound Test.
*Mewtwo is one of three characters whose Classic Mode route centers around protagonists and heroes for opponents. The other two who share this attribute are {{SSBU|Dark Samus}} and {{SSBU|Ganondorf}}. All three characters of which face heroes/protagonists from their own series.
**Similar to [[Dark Samus]], Mewtwo's teammates are based on being possessed to fight other opponents for its Classic Mode route, thus making Mewtwo's route an inverse of {{SSBU|Joker}}'s.
*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.
*Mewtwo is the only character who can [[stun]] other fighters in ''Ultimate'' without the use of items or breaking shields.
*Mewtwo, {{SSBU|Cloud}}, and the {{SSBU|Hero}} are the only three playable characters to speak in Japanese in at least one version of the game to never speak in English in any version of the game.
**Out of those three, Mewtwo is the only one who is not a property of Square Enix and is a first-party character.
*Uniquely, when Mewtwo is [[poison]]ed or under the effect of [[Eiha]] or Eigaon, it uses the same expression used for the startup of [[Disable]], and as a result, its eyes flash green until the effect wear off.
*Mewtwo is one of two ''Pokemon'' characters in ''Ultimate'' whose Japanese voice actors in the game are deceased, the other being [[Incineroar]]. Unlike Incineroar however, Mewtwo's voice actor passed away after ''Ultimate'''s release rather than before.
