'''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''.

*Clear {{SSBU|Classic Mode}} with {{SSBU|Fox}} or any character in his unlock tree, being the eighth character unlocked after {{SSBU|Wolf}}.

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 [[weight|lightweight]] fighter. Its overall mobility is among the best in the game, boasting among the fastest [[walk|walking]], [[dash|dashing]], and [[air speed|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 aerial|forward]] and [[back aerial|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 throw|up]] and [[back throw|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 tilt|up]] and [[down tilt|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 {{SSBU|Wolf}}, it makes up for instead having immense power and damage output.

Mewtwo's competitive potential is up for debate. Players like {{Sm|ESAM}} and {{Sm|Armada}} believe that Mewtwo should be ranked in the higher tiers due to its excellent mobility and damage racking game, while other smashers {{Sm|ZeRo}} and {{Sm|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 {{Sm|SDX}} have managed to get decent results.

==Changes from ''[[Super Smash Bros. 4]]''==

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 hurtbox 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. {{Sm|Abadango}}, {{Sm|WaDi}}, and {{Sm|Rich Brown}}, notable Mewtwo mains from ''SSB4'', have dropped it in favor of other characters. Although Mewtwo has initially received favorable success from {{Sm|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 {{Sm|ZeRo}} believe that Mewtwo is low-mid tier at best while others such as {{Sm|Pandarian}} believe that it is one of the worst characters in the game. As of now, Mewtwo's true viability remains questionable.

**{{buff|Psystrike deals more damage (30% → 40%).}}

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.

*{{nerf|Disable has more ending lag (FAF 47 → 52).}}

*{{nerf|Dash attack has a lower shieldstun multiplier. (1.875x → 1.3x)}}

*{{change|Forward tilt now always sends opponents in front of Mewtwo.}}

|neutralname= 

|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= 

|ftiltdmg=11% (near), 10% (mid), 9% (far)

|ftiltdesc=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.

|utiltname= 

|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 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.

|dtiltname=Tail Sweep

|dtiltdesc=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, a dashing up smash, neutral aerial, forward aerial, and up aerial.

|dashname= 

|dashdesc=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.

|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, 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 on whiff. Against shields, it is only unsafe if not spaced. It can be angled. It resembles its special move animation from ''Pokemon Stadium''.

|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 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, 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.

|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, 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 interrupt after 22 frames. As such, it is safe on shield, and can be spammed rather safely. It can also 2-frame punish at the ledge if timed correctly. As a result, Mewtwo's down smash is one of its most viable KOing options.

|nairname=Body Spark

|nairdesc=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.

|fairname=Shadow Scratch

|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. 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.

|bairname= 

|bairdmg={{ShortHopDmgSSBU|13}} (near), {{ShortHopDmgSSBU|11}} (mid), {{ShortHopDmgSSBU|9}} (far)

|bairdesc=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. Its large overall range also makes it a potent wall-of-pain tool at lower percentages.

|uairname= 

|uairdesc=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 (which can start combos at low percentages).

|dairname= 

|dairdesc=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 grounded opponents at around 140%. Its low landing lag combined with its diagonal angle also allows it to function as a low-percentage combo starter.

|grabname= 

|grabdesc=Telekinetically holds an opponent. Mewtwo's overall grab range is average.

|pummelname= 

|pummeldmg=2%

|pummeldesc=Releases a pulse of darkness into the opponent. A fairly fast pummel.

|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 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.

|bthrowname= 

|bthrowdmg=10%

|bthrowdesc=Telekinetically throws the opponent backward. Possessing 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.

|uthrowname=Psychic Whirlwind

|uthrowdesc=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.

|dthrowname= 

|dthrowdesc=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.

|edgedmg=7%

|edgedesc=Swings its tail in front of itself while climbing up.

|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. 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-cancel]]ed. 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]], 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 moderately propel Mewtwo backward, which can help or hinder its recovery depending on which way it faces. At various percentages, Shadow Ball can potentially act as a combo starter, notably into moves like dash attack or a dash grab.

|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 attacks as grabs|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.

|usdesc=[[bulbapedia:Teleport (move)|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.

|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. Useful at high percentages to guarantee a KO, but difficult to land. Due to being a projectile, Disable can also be reflected. Grants invincibility from frames 10 to 16

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.

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

===[[Taunts]]===

*'''Up Taunt''': 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]]===

SSBUMewtwoIdle2.gif|Mewtwo's second idle pose

*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!"

*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?"

*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==

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. 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.

===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.-->

*{{Sm|SDX|USA}} - The best Mewtwo player in the world prior to his hiatus. Placed 9th at {{Trn|Glitch 6}}, 17th at {{Trn|GENESIS 6}}, and 33rd at {{Trn|Frostbite 2019}}.

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.

Credits roll after completing Classic Mode. Completing it as Mewtwo has ''{{SSBUMusicLink|Pokémon|Victory Road - Pokémon Ruby / Pokémon Sapphire}}'' accompany the credits.

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).

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===

*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.

*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.

*Mewtwo is the only character who can [[stun]] other fighters in ''Ultimate'' without the use of items or breaking shields.
