Ultimate Official Site]]}}

'''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 portayal 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]].

Much like its appearances in ''Melee'' and ''Smash 4'', Mewtwo's attributes are notorious for being very polarizing, and only its falling speed and gravity are considered average. It has a tall hurtbox, but despite this, it is the 5th lightest character in the game, weighing only 77 units. However, its mobility is excellent, as it's tied for having the 17th fastest walking speed, the 8th fastest dashing speed, and the 3rd fastest air speed.

Like in its previous appearances as well, Mewtwo has a very potent air game. Its neutral aerial has a variety of uses; its very low ending lag gives it great combo potential into its other aerials, or Mewtwo can drag opponents down with it for grounded followups. Its forward and back aerials are very useful combo extenders and can KO at high percentages, with back aerial in particular covering a large area behind it. 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.

Another one of Mewtwo's primary strengths is its incredible grab game. While its grabs' speeds and ranges are only average, its throws are very versatile. Forward throw, when all of its hits connect, becomes one of the most damaging throws in the game, giving it damage racking potential and ability to refresh its stale moves. Its up and back throws are among the strongest of their kind and have better KO potential than in ''Smash 4''. 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.

In comparision 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 lock, which allows Mewtwo to start combos more consistently. Its tilts also have their uses. 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 different hitboxes, each having varying angles and 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, being able to KO at realistic percentages. Confusion has multiple functions, 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 infamous frailty; 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. Despite its aforementioned hurtbox properties, Mewtwo's tail-based attacks are still susceptible to being countered, owing to the base of its tail being a part of its hurtbox. Fully charged Shadow Ball has recoil when used in the air, which can cause an inadvertent [[self-destruct]] while off-stage. Disable is punishable if it whiffs and can be reflected because of its status as a projectile, the latter of which can easily lead to a fatal turnabout against Mewtwo at high percentages.

Aside from forward aerial and fully charged Shadow Ball, the rest of Mewtwo's KOing options can be difficult to land. Up and back throw can be risky to attempt because of its 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. 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.

In regard to playstyle, Mewtwo's is an odd combination of styles: it fits the archetype of a glass cannon, yet typically relies on bait and punish tactics and defensive maneuvers to keep opponents from performing rushdowns and capitalizing on its very tall frame and extremely light weight. This does not mean Mewtwo is forced to rely on [[turtling]], however, as its outstanding mobility, excellent air game, and overall powerful moveset make it a force to be reckoned with. As such, Mewtwo is a "high-risk, high-reward" character with a fairly high learning curve, as it has to capitalize on reads more often than not because of its frailty and susceptibility to pressure.

In spite of previously being a top tier character in ''Smash 4'', Mewtwo has overall been buffed in its transition to ''Ultimate''. It benefits greatly from the ability to dash-cancel into any grounded move, which alleviates most of the problems with its very low traction (which itself has substantially increased). Its superb mobility has become even better, and most of its viable KOing options have improved with better knockback and/or range, and has gained a few new ones as well. Its survivability has also improved slightly due to Mewtwo's increased weight, and the readdition to directional air dodges improve its own air dodge's mindgame potential.

However, Mewtwo has recieved a few nerfs, one of which is to its special moveset. Shadow Ball is smaller and slightly weaker when fully charged, which marginally worsens its KO potential. Confusion has lost most of its use as a recovery move as it halts most of Mewtwo's horizontal momentum in the air, and followups off of it can be a bit harder due to the command grab not centering opponents in the middle of the ripple. Lastly, Disable is also harder to hit on smaller characters due to its altered hitbox placements. Its already below-average frame data was worsened slightly with increased ending lag on many of its moves, most notably up smash and its grabs. Mewtwo's tail hurtbox has also slightly increased, which gives it a harder time to utilize its disjointed tail attacks. Lastly, its air dodge, commonly considered by many in ''Smash 4'' to be the best air dodge in the game due to its speed and mindgame potential, has been nerfed when it comes to frame data, having slightly increased startup and much more ending lag.

Overall, the buffs happen to override the nerfs, but to what extent is currently unknown.

<!--Needed: Up Smash damage output.-->

|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 be [[jab cancel]]ed, with notable follow-ups including itself, up tilt, down tilt, a grab, forward smash, and forward aerial.

|ftiltname=&nbsp;

|ftiltdmg=10% (near), 9% (mid), 8% (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 has KO potential at under 140% against middleweights near the ledge.

|utiltname=&nbsp;

|utiltdmg=6% (nearest), 5% (near), 4% (far), 3% (farthest), 4.5% (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. In comparison, its far hitboxes can be used for spacing. 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 Mewtwo's best combo starter and, like up tilt, has hitboxes that launch at different angles. As a result, it can combo into up tilt, a dashing up smash, neutral aerial, forward aerial, and up aerial.

|dashname=&nbsp;

|dashdesc=A lunging, dark energy-infused palm thrust. Its clean sweetspot deals above average knockback. Depending on the hitbox it hits with and the opponent's damage, it can combo into neutral, forward, and up aerial. Its disjointed hitbox grants it impressive range for a dash attack, which makes it a decent punishment option at certain distances, and potentially difficult for the opponent to punish from a proper distance.

|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.

|usmashname=Galaxy Force

|usmashdmg={{ChargedSmashDmgSSB4|1}} (hits 1-3), {{ChargedSmashDmgSSB4|1}} (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. Due to it hitting on frame 9, it is quite fast for a smash attack, and has the lowest amount of start-up lag out of Mewtwo's smash attacks. It hits multiple times, which makes it a useful anti-air attack. However, its 33 frames of ending lag is the highest amount of out Mewtwo's smashes, which in turn makes it 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. It has 22 frames of ending lag, which is the lowest amount out of its smash attacks, and can be interrupted rather early. As its power grants it safety against shields, it is useful for hard punishes and can be spammed rather safely. Due to it hitting on frame 21, however, it has the highest amount of start-up lag out of Mewtwo's smash attacks.

|nairname=Body Spark

|nairdesc=Discharges electricity around itself. Its hitboxes are positioned at Mewtwo's hands and feet and keep the opponent trapped, whereas its last hitbox launches them. As a result, it is very useful for disrupting opponents, as Mewtwo has full control over its aerial movement during the attack.

|fairname=Shadow Scratch

|fairdesc=A dark energy-infused swipe. Due to it hitting on frame 6, it has the lowest amount of start-up lag out of Mewtwo's aerial attacks. When coupled with its respectable damage output and high knockback scaling, it is one of Mewtwo's most viable KOing options. It also boasts combo potential at low percentages, as it can also combo into itself, or be used as a follow-up from down tilt or neutral aerial.

|bairname=&nbsp;

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

|bairdesc=Swings its tail in an upward arc. It has a very large range, which makes it a decent gimping option when timed properly. Due to it hitting on frame 13, however, it has the second highest amount of start-up lag out of Mewtwo's aerial attacks. A powerful edgeguarding tool due to its aforementioned reach and having high knockback at its sweetspot.

|uairname=&nbsp;

|uairdmg={{ShortHopDmgSSBU|11}} (near), {{ShortHopDmgSSBU|10}} (mid), {{ShortHopDmgSSBU|9}} (far)

|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.

|dairname=&nbsp;

|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.

|grabname=&nbsp;

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

|pummelname=&nbsp;

|pummeldmg=2%

|pummeldesc=Shocks the opponent with darkness. 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 forward 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.

|bthrowname=&nbsp;

|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. It KOs middleweights at around 95% near the ledge.

|uthrowname=Psychic Whirlwind

|uthrowdesc=Telekinetically whirls the opponent around itself before launching them upward above its head. One of the strongest up throws in the game, while being difficult to properly DI due to its purely vertical angle. It KOs middleweights at around 131% on Final Destination.

|dthrowname=&nbsp;

|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, though it can be used to punish an opponent's reaction.

|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]], though it cannot break one with full health and can still cancel out certain projectiles. A fully charged Shadow Ball also deals recoil upon being fired; as a result, using it in midair will moderately propel Mewtwo backward, which can help or hinder its recovery.

|ssdesc=Swipes forward to [[bulbapedia:Confusion (move)|emit a ripple of psychic energy]] from its hand. It has impressive utility, thanks to it functioning as a [[reflector]], a [[Grab#Special attacks as grabs|command grab]], and even a recovery option. As a grab, the ripple spins opponents around and leaves them [[tumbling]] downward, dropping them in front of Mewtwo and allows it to follow-up with other attacks. As a recovery option, its first use in midair gives Mewtwo a slight vertical boost, 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.

|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 making eye contact with it. If the opponent is in the air, they are slightly launched backward with set knockback, instead of being stunned. Useful at high percentages to guarantee a KO, but difficult to land. Due to being a projectile, Disable can also be reflected. The move itself can be reversed.

|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.

*Thrusts its hand forward, radiating dark energy while groaning. 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!"

*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 then poses while laughing. In Japanese, it says {{ja|愚かな！|Orokana!}}, which translates to "Foolish!"

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. 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.

*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 is the only [[DLC]] veteran who was playable in the E3 demo.

*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.
