—Introduction Tagline

Mewtwo (ミュウツー, Mewtwo) is a playable character in Super Smash Bros. 4. Mewtwo was confirmed to be returning to the series as a playable character during the Super Smash Bros. for Wii U 50-Fact Extravaganza on October 23rd, 2014 and was made available to the public on April 28th, 2015; however, it was available early as a free download beginning on April 15th to players who registered both Super Smash Bros. for Wii U and Super Smash Bros. for Nintendo 3DS on Club Nintendo before March 31st, 2015.. Its appearance in Super Smash Bros. 4 makes it the first downloadable character in Super Smash Bros. history; it also makes it the second of three Super Smash Bros. Melee characters that were cut from Super Smash Bros. Brawl to return for Super Smash Bros. 4, after Dr. Mario and preceding Roy.

Mewtwo is now voiced by Keiji Fujiwara, replacing Masachika Ichimura from Super Smash Bros. Melee. As in Melee, Mewtwo has fully voiced victory quotes in Japanese (which are re-recorded versions of its Melee quotes), though they were removed for international versions. Its phrases, and most of its grunts and other voice clips, are inspired by those from Melee.

Mewtwo is currently ranked 37th out 56 on the tier list, placing it in the F tier. This is a notable improvement from its ranking of 21st out of 26 in Melee, though it is still the lowest-ranked DLC character. Mewtwo's mobility has noticeably improved and its entire moveset has been generally reworked to be less awkward and more usable than before. Many of its attacks have been improved, with Confusion and Disable in particular becoming much more useful, while its ground, air, and grab games have become very potent. However, it remains held back by its vulnerability to combos and juggling, as well as its abysmal endurance, the latter of which is worsened due to a slight increase in its already tall frame and its weight having been drastically reduced to being the second lightest in the game, surpassed only by Jigglypuff. Mewtwo's other issues include its approach being weakened by the general changes of Brawl and SSB4 removing wavedashing and moonwalking and weakening dash-dancing, while its attacks have become slower. However, its current position remains a heavy subject of debate, as Mewtwo's numerous useful buffs received from update 1.1.5 make it much more rewarding than it was in Melee, and has lead to it gaining some notable tournament representation and results, the most notable of which being Abadango winning Pound 2016 using almost completely Mewtwo.

Attributes

Mewtwo has polarizing characteristics: it has fast dashing and air speeds, making it a very mobile character, which is complemented by its above average damage output. However, it is the second lightest character in the game, and despite its high air speed, it has the third lowest air acceleration, average gravity and falling speeds, and a large overall frame, making landings and approaches safely difficult. Many of Mewtwo's attacks are from its long-reaching tail, but it deals more damage at close range.

Mewtwo's throws are among the most potent in SSB4, giving it a very threatening grab game despite it being toned down from Melee. Its forward throw has a very high damage output that makes it very useful to refresh its most stale moves. Its back and up throws are among the strongest throws in the game, making them reliable KOing options. Despite its down throw having no true combo potential, it can still lead into a plethora of moves if the opponent does not react properly due to it launching them just out of counterattacking range. Despite this, Mewtwo's grab has low range, especially for a character of its size. This can often result in its grab missing from a range where players would expect it would surely connect from.

Mewtwo's ground game is a mixed bag; while it is long-ranged and powerful, all but a few of its ground moves (including down smash and down tilt) suffer from noticeable ending lag. As a result, its ground moves are risky to use if it they do not connect or are shielded. Its jab is very useful, as it is easily capable of leading into a jab cancel. This enables Mewtwo to better utilize its effective grab game, quickly initiate combos when followed up by its up or down tilts, or act as a setup to Disable. Unlike its other tilts, Mewtwo's forward tilt is powerful enough to KO, particularly near the ledge. Mewtwo's dash attack, while punishable, still provides respectable range and knockback. Finally, its smash attacks all have above average strength; up smash in particular is the most powerful and fastest of the three, while it can also function as a powerful anti-air option.

In comparison to its ground game, Mewtwo's aerial game is potent overall; its aerial moves deal respectable damage, high knockback and the ability to combo into themselves. Neutral aerial has a long lasting active hitbox that can shield stab, outlast airdodges and start combos if landing as the enemy is being hit, although it loses this hitbox when Mewtwo lands. Mewtwo's forward aerial boasts impressive startup, power, and range alongside the ability to combo into itself at low percentages and the ability to KO at higher percentages. Its back aerial is similar to the forward aerial, but has a slow startup to offset the very large sweeping hitbox behind itself while also possessing the ability to combo into itself before becoming a KO option at high percentages. Mewtwo's up aerial is a standard sweeping attack of moderate power. Its down aerial is somewhat fast for a meteor smash and it can KO at high percentages. However, it is the slowest of its aerials, and has the most landing lag. This, combined with the move not having much in terms of combo ability makes it its worst aerial move, though it is still decent overall.

Finally, its special moves are powerful, although risky, much like its ground game. Shadow Ball is one of the strongest and fastest projectiles in the game when fully charged. Teleport's ending lag, momentum, and startup have been increased since Melee, and while these traits make it generally more risky to use when warping to the floor due losing its ability to play mindgames (due to its animation being different from its airdodge), it is still useful due to its range and because it renders Mewtwo invulnerable for a split second as well as giving it considerable horizontal momentum. Confusion and Disable, both of which were notorious in Melee for being virtually useless, have been buffed considerably and now help in Mewtwo's neutral game.

Mewtwo's buffed Confusion helps its defense due to it now being a proper reflect and also helps its offense due to it acting as a long-range command grab, which can enable it to grab even highly disjointed attacks such as Ike's forward smash. Confusion also helps Mewtwo's recovery somewhat due to granting it a slight vertical boost when used in midair and can completely reverse aerial momentum and direction. Disable now immobilizes the opponent longer depending on how damaged they are and has decreased cooldown. Despite their vast improvements, however, Confusion and Disable have noticeable ending lag.

Despite Mewtwo's strengths, it has notable and exploitable weaknesses. Like Fox, the most notable of them is its frailty; Mewtwo's tall frame combined with its low weight makes it very easy to KO, but its tall frame coupled with its average falling speed and high enough gravity make Mewtwo an easier character to combo than other characters of its size such as Rosalina and Palutena. This leads to Mewtwo being brought to KO percentages more easily than potentially any other character in the game. However, unlike Fox, it is also susceptible to juggling due to its gravity being low enough and lacking a long-lasting down aerial move to cover its landing although it can use Teleport to go under the opponent as a risky choice.

In general, Mewtwo's playstyle is very similar to Palutena's with her default moveset, with a slightly higher risk but a much higher reward. Like Palutena, Mewtwo must use defensive maneuvers to keep opponents from performing rushdowns and gaining the advantage at all costs, being hindered with an even taller frame and lighter weight than her. However, rather than being forced to turtling as she is, Mewtwo is more mobile in the air and has a more powerful and reliable projectile and reflector, a notably higher overall damage output than her, a better grab game despite its combo throw being worse than her's, and significantly better frame data. This makes Mewtwo an odd combination between a defensive punishment-oriented character and a speedy glass cannon that sacrifices attack speed for damage and power. Ultimately, this classifies Mewtwo as a "high risk, high reward" character like Little Mac and Jigglypuff; due to possessing a number of KOing options that have capable reach (two of which are throws), yet being burdened with very light weight and a susceptibility to combos and juggling, it will have to capitalize on reads more often than not.

After being buffed heavily by update 1.1.5, Mewtwo has received more representation and better results in the western scene. Notable performances include Blue defeating Nairo and Mew² defeating Mew2King. This resulted in Mewtwo being regarded as a much better character within the western scene than initially thought, with most players considering it to be a mid tier character at minimum. However, most recently, Japanese player Abadango huge tournament Pound 2016 using Mewtwo almost exclusively, defeating many notable players such as Marss, VoiD and Ally. In light of Abadango's performance, many players have no doubt in considering Mewtwo to be a relatively useful potential high tier character, in stark contrast to it's initial low tier placements.

Changes from Melee

Mewtwo has received a mix of buffs and nerfs in the transition from Melee to SSB4, but has been buffed overall as of update 1.1.5.

First and foremost, Mewtwo has received many notable improvements; for instance, its aerials are better (its down aerial being the most heavily buffed in the game in terms of power), with highly reduced landing lag and added power. It also no longer has the worst tech in the game. More specifically, two specials that were previously viewed as useless, Disable and Confusion, were buffed in speed, usage, and the capability to chain into combos. Confusion in particular is now able to transfer projectiles to Mewtwo's ownership, improving its offense, defensive play against projectiles, and assisting in mindgames. Mewtwo's smash attacks were also buffed, with significant increases in knockback being applied to both its forward smash and up smash, improving its previously poor KO ability. Mewtwo can also dash significantly faster, which greatly helps its ground game and Mewtwo's overall mobility. Also, Mewtwo retains a very powerful up throw and a forward throw that can both deal respectable damage and help refresh moves affected by stale-move negation. The removal of directional air dodging and more landing lag with an air dodge is also a significant buff to its Shadow Ball, which can be used to trap landings much more easily. The new air dodge mechanics also give Mewtwo an option when attempting to land. Finally, its new wall jump improves its recovery options.

However, Mewtwo has received significant nerfs, especially to its survivability. One of Mewtwo's biggest nerfs in this transition is a large decrease to its already low weight (now being a mere six units heavier than Jigglypuff) and a slight increase to its already tall hurtbox, making Mewtwo significantly easier to KO. Teleport, formerly one of its reliable defensive options, has more landing lag, weakening its mix-up utility and its ability to escape pressure. Many of Mewtwo's attacks also have slightly more start-up. The loss of wavedashing also harms Mewtwo, as it aided its combo game and approach in Melee. The removal of double jump cancelling is a double-edged sword. Although it improves Mewtwo's recovery, it also weakens its combo game, as with the loss of wavedashing. Its throw-oriented combo game has been toned down significantly; the removal of chaingrabbing as well as the generally slower fall speeds means Mewtwo can no longer chaingrab with its up or down throws, while its down throw now has slightly more ending lag, making it one of the only characters with a down throw that cannot combo properly.

Overall, Mewtwo has been re-balanced so that its moveset is generally more consistent than in Melee, but its survivability, approach and combo options have been nerfed due to its lighter weight and the changes in mechanics from Melee to SSB4. Additionally, Mewtwo is at a distinct disadvantage in a custom moveset environment since it lacks custom moves due to its status as a downloadable character. As such, Mewtwo still has a rather high learning curve and risky playstyle, though it still functions as a rather effective glass cannon.

Aesthetics

• Mewtwo's design has undergone various changes much like the other playable Pokémon in SSB4. Its proportions more closely resemble its most recent appearances in the core Pokémon games, with a smaller head, lighter skin and more bulbous fingers, which are different than that of the design used for its initial trophy.
• Like many characters, Mewtwo's front side faces the screen regardless of which direction it is looking.
• Mewtwo is less vocal overall, as it no longer uses a sound effect when using Confusion, Disable and battering items.

Attributes

• Mewtwo is lighter (85 → 74), now being the second lightest character in the game.
• Mewtwo walks faster (1.0 → 1.1).
• Mewtwo dashes faster (1.4 → 2.05), going from being tied for the tenth slowest in Melee to the seventh fastest in SSB4.
• Mewtwo's air speed is faster (1.2 → 1.25), giving it the third fastest air speed.
• Although Mewtwo retains its regular falling speed from Melee (1.5), its fast falling speed is faster (2.3 → 2.4). When combined with the new air dodge mechanics compared to Melee, this can help Mewtwo land easier.
• Mewtwo's short hop, full hop, and double jump heights are all slightly higher.
• Mewtwo is slightly taller, making it easier to hit and combo in certain situations.
• Mewtwo crouches lower.
• The removal of double jump cancelling helps and hinders Mewtwo. It improves Mewtwo's recovery, as it can now use aerials or air dodges while keeping its momentum. However, it also impairs Mewtwo's combo game.
• The removal of wavedashing and moonwalking and the weakening of dash-dancing all significantly hinder Mewtwo's approach.
• The removal of chain grabbing hinders Mewtwo's damage racking abilities, as it can no longer chain grab with its up or down throws.
• Mewtwo can now wall jump.
• Mewtwo's tech animations have been changed. They are now more traditional, making it harder for Mewtwo to be tech-chased.
• Some of Mewtwo's tail-based attacks do not match its attack trails.
• Item swings have different animations and dash swings no longer have a multiple hit behavior.

Ground attacks

• Neutral attack's first and loop hits deal less damage (6% → 4% (first hit), 2% → 1% (loop)).
• Neutral attack has decreased ending lag (30 → 25).
• Neutral infinite now has a finisher, an upward swipe. It also comes out 2 frames earlier (frame 8 → 6)
• Neutral infinite's animation has been slightly changed. Mewtwo now moves its body and its attacking arm is slightly bent instead of pointing straight forward.
• Dash attack has been improved. Its earliest sweetspot deals 1% more damage (9% → 10%) and it deals more knockback, being able to KO at realistic high percentages. It also has better range; its hitboxes are now disjointed from Mewtwo's hands as opposed to only just reaching the end of its hands and they have become larger, with the furthest hitbox now being larger than the hitbox closer to its body.
• Dash attack's late hit's lingering duration is 9 frames shorter.
• Dash attack's animation has slightly changed. Mewtwo now performs a palm thrust while supporting its dominant hand with its other hand, rather than a double palm thrust.
• Forward tilt has increased ending lag (32 → 36), comes out 2 frames later (frame 8 → 10) and lasts 1 frame shorter.
• Down tilt deals less damage (9% → 5% (near), 5% → 4% (far)), comes out 1 frame later (frame 5 → 6) and lasts 1 frame shorter.
• Down tilt has decreased ending lag (30 → 21).
• Up tilt comes out 2 frames later (frame 6 → 8).
• Up tilt deals less damage (10%/8%/6%/5% → 6%/5%/4.5%/4%/3%). However, the decreased damage output lets the move chain into itself easier, and can set up for an aerial follow up at higher percentages.
• Up tilt has decreased ending lag (32 → 30).
• All smash attacks have decreased ending lag (60 → 53 (forward), 80 → 69 (up), 60 → 44 (down)).
• Sweetspotted forward smash deals 1% less damage (20% → 19%), but its knockback has been somewhat compensated.
• Sourspotted forward smash deals 4% more damage (12% → 16%).
• Forward smash has increased knockback across all hitboxes, has a bigger hitbox size (2u → 3u), and the sweetspot is easier to land than the sourspot. Its hitbox duration is also 1 frame longer.
• Forward smash has slightly less range and the move also comes out 1 frame later (frame 18 → 19).
• Forward smash's start-up animation has slightly changed. Mewtwo now rears back both arms to one side, rather than rearing back each arm to each side.
• Up smash deals 1% more damage (16% → 17%) and is significantly stronger, now being able to KO under 75% when fully charged and all of its hits land. The first six hits also connect together better.
• Up smash's initial hitbox is very slightly smaller, but it connects together better into the first six hits, which are also slightly larger. The last hit has slightly less vertical range, but slightly more horizontal range.
• Down smash has increased knockback growth (103 → 118) and has slightly more range.
• Down smash comes out 1 frame later (frame 20 → 21).

Aerial attacks

• All aerials have decreased landing lag (17 → 13 (neutral), 25 → 14 (forward), 28 → 17 (back), 20 → 13 (up), 28 → 18 (down)).
• Neutral, forward and down aerials have decreased ending lag (55 → 46 (neutral), 40 → 38 (forward), 58 → 46 (down)).
• Back and up aerials have increased ending lag (32 → 40 (back), 38 → 40 (up)).
• Neutral, forward, back and up aerials have increased autocancel frames (37> → 46> (neutral), 35> → 36> (forward), 30> → 38> (back), 33> → 36> (up)). While its neutral aerial is unable to autocancel from a short hop, Mewtwo's slightly increased jump height enable its forward, back and up aerials able to autocancel from a short hop.
• Down aerial has decreased autocancel frames (45> → 42>). Mewtwo's slightly increased jump height enables it to autocancel immediately from a short hop.
• Neutral aerial deals 8% less damage (20% → 12%) and comes out 2 frames later (frame 5 → 7). It has also lost its landing hitbox.
• The first 8 hits of neutral aerial connect better, and the last has a bigger hitbox that also deals increased knockback.
• Neutral aerial's animation has slightly changed. The electricity now flashes green, yellow, blue, cyan and purple at varying intervals instead of consistently flashing mauve and cyan.
• Forward aerial deals 1% less damage (14% → 13%) and lasts 1 frame shorter.
• Forward aerial has increased horizontal range, knockback and comes out 1 frame earlier (frame 6 → 5). The hitboxes are also more disjointed from Mewtwo's arm.
• Forward aerial's launch angle is more diagonal, which allows it to string into itself in another way. Its KO potential is also horizontal rather than vertical.
• Forward aerial's animation has slightly changed. Mewtwo now swipes in a scooping motion instead of turning its body inward towards its swiping direction.
• Back aerial's x-axis offset was increased (5.1 → 5.5).
• Back aerial comes out 1 frame later (frame 12 → 13).
• Near up aerial deals 1% more damage (10% → 11%). It also has better combo potential, can KO much earlier near the upper blast line and lasts 1 frame longer.
• Mid and far up aerial deals less damage (11% → 10% (mid), 14% → 9% (far)). It also comes out 1 frame later (frame 9 → 10).
• Up aerial's sweetspot is now placed near Mewtwo's body as opposed to the tip of its tail, no longer having a tipper.
• Aerial sweetspotted down aerial deals 1% less damage (16% → 15%).
• Down aerial has been improved. It is now significantly stronger, comes out 3 frames faster (18 frames → 15) and lasts 2 frames longer (2 → 4). Its hitboxes are much larger and more disjointed from Mewtwo's leg, giving it increased vertical and horizontal range below it.
• Down aerial's animation has slightly changed. Mewtwo now thrusts its leading foot downward in a more pronounced stomping motion and exudes more darkness visual effects.

Throws/other attacks

• Standing and dash grabs increased ending lag (32 → 36 (standing), 40 → 43 (dash)). Dash grab also comes out 1 frame later (frame 8 → 9).
• Pummel deals 1% less damage (3% → 2%).
• Pummel is faster.
• Forward throw deals 2.5% more damage. (10.5% → 13%). Its Shadow Balls are larger and pass through the thrown opponent, generally making them more reliable.
• Forward throw's Shadow Balls do not travel as far as they did in Melee.
• Forward throw's animation has been changed. Mewtwo now levitates and has one of its feet planted down during the throw.
• Back and down throws deal less damage (11% → 10% (back), 11% → 9% (down)). The lower damage outputs in particular make back throw slightly weaker.
• Back throw has a new animation. Mewtwo now levitates and then throws an opponent in a backhanded motion without looking behind itself.
• Up throw is weaker, KOing 20%-30% later. It also has slightly increased lag, making it more punishable at low percentages. However, it is still the strongest up throw in the game if DI is taken into account.
• Down throw is slightly faster.
• Down throw has slightly increased ending lag, limiting its combo potential and set-ups, and now requiring hard reads.
• Down throw has an altered angle (69° → 74°).
• Down throw's animation has been slightly changed. Mewtwo now does a front flip instead of a full body spin.

Special moves

• Fully charged Shadow Ball is much stronger, has a larger hitbox and has increased range.
• Shadow Ball's charging time has increased and it no longer has a hitbox while charging.
• Shadow Ball's movement pattern is less erratic. While this increases its accuracy, its trajectory is more predictable.
• Shadow Ball pushes Mewtwo back further when fully charged, especially in midair. While it improves Mewtwo's defensive options and recovery if used correctly, it can also increase the risk of it accidentally self-destructing while off-stage.
• Darkness emanates from both of Mewtwo's hands instead of just one while saving a fully charged Shadow Ball.
• Confusion deals ≈0.9505% less damage (10% → ≈9.0495%).
• Confusion now behaves like a traditional reflector, as it changes reflected projectiles to Mewtwo's ownership and it has a damage multiplier (1.4x).
• Aerial Confusion gives Mewtwo a slight vertical boost after its first use, which slightly improves Mewtwo's vertical recovery.
• Confusion now consists of eight small hits instead of one large hit.
• Confusion's animation has changed. It is now depicted as a ripple of psychic energy rather than a flash of energy, which makes it very closely resemble the animation it has used since Pokémon Black and White.
• Teleport provides Mewtwo with a small amount of forward and/or backward momentum.
• Teleport plays out its momentum-granting ending lag even if Mewtwo re-appears on the ground, leaving it open for half a second. It also has an altered animation that differs from its air dodge, removing mindgame potential.
• Teleport has increased start-up, making it slightly easier to punish. However, the increased start-up makes Teleport's direction easier to control.
• Disable's stun duration has increased and its cooldown has decreased, making it much more reliable as a set-up.
• Disable no longer launches or tumbles a stunned or aerial opponent. Instead, it only deals minor damage and minor knockback.
• Disable's animation has slightly changed. Mewtwo now tilts its head at an angle and its eyes turn green.
• Mewtwo now has a Final Smash, Psystrike. Mewtwo undergoes Mega Evolution to become Mega Mewtwo Y and then immediately uses Psystrike, a powerful sphere of psychic energy that is fired from its palm. Psystrike is able to pass through walls and if it hits any opponents, they are then launched after a powerful mental shock.

Update history

Mewtwo has been heavily buffed as of update 1.1.5. Some of its attacks have had their damage outputs increased, their lag decreased, and their hitboxes' sizes and durations increased, all of which improve its offense. Additionally, update 1.1.3 made Mewtwo considerably faster by increasing its walking and dashing speeds, which further helps its offensive prowess by enabling it to chase after opponents and thus allows it to mix up its playstyle to sport a more consistent offensive presence alongside its typically defensive presence. Mewtwo's dash speed was increased even further in update 1.1.5, now being slightly faster than Sheik's. Said update also slightly increased Mewtwo's incredibly light weight, which marginally improved its survivability issues. Mewtwo also slightly benefits from the changes to shield mechanics brought about by updates 1.1.0 and 1.1.1; the universal increase to shieldstun allows Shadow Ball, some of its sweetspotted attacks and Confusion-reflected projectiles (such as a reflected tree, a fully charged Charge Shot or a fully charged Shadow Ball) to heavily damage a shield. Due to these aforementioned changes, Mewtwo is considered much more viable than it was upon release, with players considering it to be mid-tier at the least, many players even considering it to be high tier, as opposed to its current low-tier status.

1.0.8

• Neutral aerial's landing lag decreased: 19 frames → 16.
• Up smash's initial hitbox size decreased.

1.1.0

• Forward throw deals 2.5% more damage: 10.5% → 13%.
• Down smash's knockback growth increased: 112 → 118, KOing 9% earlier.
• Air dodge's animation slightly changed. If Mewtwo air dodges while holding an item, the item will disappear as well. This enables Mewtwo to avoid giving away its location, although this can be mitigated if its name tag is visible or if the bottom screen marker is placed on it.

1.1.3

• Mewtwo walks and dashes faster, with the latter going from being tied with Wii Fit Trainer as the twenty-second fastest to being tied with Meta Knight as the twelfth fastest.
• Sourspotted forward smash deals 1% more damage: 15% → 16%.
• Forward smash's hitbox size increased.
• All aerials' landing lag decreased: 16 → 13 (neutral, up), 18 → 14 (forward), 21 → 17 (back), 22 → 18 (down)).
• Forward aerial's start-up decreased by 1 frame.
• Forward and down aerials' ranges increased due to their hitboxes having moved 1 unit forward and downward, respectively.
• Back aerial's x-axis offset increased.
• Up aerial deals more damage: 7% → 9% (far), 9% → 10% (mid).
• Up aerial's hitboxes' sizes and knockback increased.
• Down aerial's hitbox duration increased by 2 frames.
• Down throw's angle altered: 69° → 74°.
• Shadow Ball's hitbox size increased.
• Aerial Shadow Ball's recoil decreased. While this helps Mewtwo become less susceptible to self-destructing, it also slightly hinders Mewtwo's usage of the recoil as a form of horizontal recovery.
• Shadow Ball's visuals improved.
• Confusion's range increased due to its grab parameter having become larger.

Moveset

		Name	Damage	Description
Neutral attack			4%	Extends its arm and releases repeated pulses of dark energy, finishing with an energy-infused swipe. The first hit can be jab cancelled, which allows Mewtwo to combo it with another neutral attack, a throw or any other attack.
			1% (loop), 2% (finisher)
Forward tilt			10% (near), 9% (mid), 8% (far)	Swings its tail forward. Can be angled and has good range, but has low knockback.
Up tilt			6% (nearest), 5% (near), 4% (far), 3% (farthest), 4.5% (farthest hitbox to opponents in front of Mewtwo)	Does a flip, striking opponents with its tail. Deals more damage the closer the opponent is to Mewtwo, has high range, and can hit opponents near Mewtwo's back. Can juggle point blank opponents with two or more hits.
Down tilt			5% (near), 4% (far)	Mewtwo crouches and sweeps its tail 180°. Mewtwo's fastest tilt, though severely lacking in knockback. Good as an out of shield option. It is also Mewtwo's best combo starter, being able to combo into a neutral, forward or up aerial, an up smash and more.
Dash attack			10% (clean sweetspot), 9% (clean sourspot), 6% (late sweetspot), 4% (late sourspot)	Lunges forward and performs a dark energy-infused palm thrust. Has above average knockback if hit with the clean sweetspot. Depending on the hitbox it hits with and the opponent's percentage, it can combo into a neutral aerial, forward aerial, and up aerial.
Forward smash			19% (blast), 16% (arms)	A double palm thrust that releases a blast of dark energy. Moderate start-up, but rather low ending lag and powerful enough to KO quite reliably. KOs at around 114% while the sourspot KOs at around 122%.
Up smash			1% (hits 1-6), 10% (last hit)	Thrusts its arm upwards and conjures a galaxy-shaped swirl of dark energy. Can fail to hit small foes, but the final hit deals the highest knockback any of Mewtwo's smash attacks. Good for trapping aerial foes, particularly those near the edge. KOs at around 107% if all of its hits connect.
Down smash			15%	Extends its arm downwards and launches a burst of dark energy from its fingertip near its feet. Similar to forward smash, but also has the benefit of having slightly less endlag. One of the few down smashes that does not hit on both sides. KOs at around 111%.
Neutral aerial			1% (hits 1-8), 4% (last hit)	Mewtwo discharges electricity around itself, with the last hit launching opponent back. The hitbox stays at Mewtwo's body. It has lost its landing hitbox since Melee, meaning opponents could end up close to it if the move ends early, but it is a good move for disrupting opponents regardless.
Forward aerial			13%	A dark energy-infused swipe. One of the fastest and most powerful forward aerials in the game, having 5 frames of start-up and KOing at around 143%. At lower percentages, it can easily be used as a follow-up after a down tilt or a neutral aerial. It can also combo into itself at lower percents as well.
Back aerial			13% (near), 11% (mid), 9% (far)	Whips its tail behind it. It has highly disjointed range, but does more damage when the opponent is closer to Mewtwo's body.
Up aerial			11% (near), 10% (mid), 9% (far)	Mewtwo backflips whike striking opponents with its tail, similarly to its up tilt. Does more damage when the opponent is closer to Mewtwo's body. As it has mainly a vertical hitbox, it is unable to hit opponents beside Mewtwo.
Down aerial			14% (grounded opponents, aerial sourspot), 15% (aerial sweetspot)	Mewtwo backflips and performs a downward arcing stomp while its foot is infused with dark energy. It has decently fast start-up in proportion to its very high knockback growth, being a powerful meteor smash when sweetspotted. Grounded opponents are launched diagonally upward with high knockback, which further makes it a very good KOing option.
Grab			—	Telekinetically grabs a nearby opponent.
Pummel			2%	Zaps the opponent. Average speed.
Forward throw			3% (throw), 2% (Shadow Balls)	Telekinetically throws the opponent diagonally in the air before firing five small Shadow Balls at them. As of update 1.1.0, it is tied with Ganondorf's and maximum aura Lucario's forward throws as the most damaging forward throws in the game. However, the Shadow Balls can be reflected if the opponent wears a Franklin Badge.
Back throw			10%	Telekinetically tosses the opponent behind it. Has good KOing potential at high percents near the edge, starting at 132%. One of the strongest back throws in the game.
Up throw			12%	Telekinetically swirls the opponent around its body before launching them upward. Due to the throw's high base knockback, launching angle which is difficult to DI against, and the aforementioned DI having minuscule effect on its KO potential, this makes it a reliable KOing option on any character at around 140%. Arguably the most powerful up throw in the game, being tied with Charizard's, whose up throw has more knockback and KOs slightly later with proper DI than Mewtwo's with proper DI (though Charizard's KOs slightly earlier with no DI).
Down throw			4% (hit 1), 5% (throw)	Telekinetically slams the opponent to the ground and spins to whip them with its tail. It has low knockback, however, it contains somewhat high ending lag. Because of this, it cannot properly combo into most of its moves. It is only usable to react to an opponent's options and punish it.
Forward roll Back roll Spot dodge Air dodge		—	—
Techs		—	—
Floor attack (front) Floor getups (front)			7%	Levitates and spins around, striking opponents with its tail.
Floor attack (back) Floor getups (back)			7%	Same as its frontal floor attack.
Floor attack (trip) Floor getups (trip)			5%	Gets up and swipes on both sides.
Edge attack Edge getups			7%	Gets up and swipes its tail in front of itself.
Neutral special	Default	Shadow Ball	2.5% (minimum charge), 25% (full charge)	Charges a large, dark purple sphere of dark energy. It can then be fired immediately or can be cancelled, then charged up again. While its charge time is quite long, a fully charged Shadow Ball is one of Mewtwo's viable KOing options, as it KOs at around 112%. If used in the air, the recoil will propel Mewtwo backwards considerably, which can help or hinder its recovery. A fully charged Shadow Ball has transcendent priority, but can still cancel out certain projectiles. Deals a great amount of shield damage if fully charged, but not quite enough to break one.
	Custom 1	N/A
	Custom 2	N/A
Side special	Default	Confusion	≈9.0495% (throw), 1.4x (reflected projectiles)	Summons a ripple of psychic energy. Has impressive utility due to functioning as a grab, a reflector 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, the first use in midair gives Mewtwo a slight vertical boost.
	Custom 1	N/A
	Custom 2	N/A
Up special	Default	Teleport	0%	Disappears and then reappears soon after in a different place. It is completely invulnerable during the move. It has less ending lag if warping directly back onto the ground. It also gives Mewtwo some horizontal momentum if ended in midair.
	Custom 1	N/A
	Custom 2	N/A
Down special	Default	Disable	1%	Crouches slightly and immediately launches a minuscule spark of psychic energy from its eyes toward the opponent, stunning them. It only works if the opponent is facing Mewtwo and making eye contact with it. If the opponent is in the air, they are slightly launched backward with set knockback. Useful at high percentages to guarantee a KO, but difficult to land. It should be noted that Disable can be reflected by a particularly vigilant opponent.
	Custom 1	N/A
	Custom 2	N/A
Final Smash		Psystrike	30%	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 foes and walls, and any opponent caught will be stunned before being launched by an intense, mind-shattering blow.

On-screen appearance

• Emerges from a large mass of dark energy and then falls gently to the ground. It is similar to Lucario's on-screen appearance, albeit with dark energy involved instead of aura.

Taunts

• Up taunt: Closes its eyes and folds its arms as it levitates on the spot, spinning around as it laughs sinisterly. This taunt returns from Melee.
• Side taunt: Surrounds itself in a flame-like field of dark energy, similarly to Lucario's up taunt.
• Down taunt: Faces the screen while its eyes glow, thrusts its arm towards the screen, and emits a small spark of dark energy while posing similarly to its official art in Super Smash Bros. 4.

Victory poses

A small excerpt of the Pokémon Red and Blue title theme.

• Turns its back to the screen and looks back over its shoulder, saying "Hmm..." In the Japanese version, it says "私はなぜ ここにいるのか...？", which translates to "Why am I here?"
• Thrusts its hand forward, emits dark energy from its body, and growls. Appears very similar to its down taunt. In the Japanese version, it says "私はまけるわけにはいかない！", which translates to "I cannot lose!"
• Does a single spin and then poses while laughing ominously and emitting a flame-like field of dark energy around itself. In the Japanese version, it says "愚かな！", which translates to "Foolish!"

Trophies

Mewtwo's DLC contains matching character trophies, which are unlocked as usual (its alternate trophy will also be automatically granted on start-up in the version.) Its existing non-fighter trophy remains in the game, completely unchanged; both it and the Classic trophy are simply labeled as "Mewtwo" in-game.

Mewtwo

Mewtwo puts its psychic powers to great use in this game. Not only does it have floaty jumps, but its telekinesis gives its attacks extra reach and its throws added power. However, its light body makes it easy to launch, so if you're willing to take the risk of getting in close, it might just be worth it!

Mewtwo (Alt.)

Mewtwo's Confusion side special not only repels projectiles—it also reflects the damage back on your opponent. Its down special, Disable, stuns an enemy for longer the higher its damage is. Disable only works on foes that are facing Mewtwo.

Psystrike

Mewtwo's Final Smash starts as Mewtwo Mega Evolves into Mega Mewtwo Y. It then fires a huge psychic projectile that penetrates enemies and obstacles. This projectile doesn't do any damage, but it freezes every foe it hits in place. They can even be frozen midjump! Afterward, every foe hit with this projectile will take a powerful psychic hit to the head.

Mewtwo (non-fighter)

Created from modified Mew DNA, Mewtwo was designed to be the ultimate Pokémon. It didn't take on any of Mew's kinder traits and only uses its intelligence to destroy its enemies. Or...so it seems. Perhaps it just feels frightened or even tormented, and that's why it lashes out. Whatever the reason, Mewtwo is not to be messed with.

Trivia

• Mewtwo's official artwork is posed nearly identically to its official Melee artwork.
• As a likely callback to Melee, Mewtwo has only one voice clip for when it is KO'd.
• Mewtwo folds its arms in several of its animations. These include its up taunt, Hammer animation, up tilt, helpless, asleep and teeter, result screen animations, and, humorously, its screen KO animation.
• The visual trails left by Mewtwo's tail attacks change color depending on the costume chosen.
• As Mewtwo is a DLC character, it lacks custom moves. However, prior to update 1.0.7 it was possible to access buggy versions of Mewtwo's special moves via a glitch involving shared Mii Fighters. Most of these crash the game, with the exception of both variations of Confusion, a non-functional version of Disable that sends Mewtwo into its helpless state, and a version of Disable which zooms the camera in on Mewtwo and temporarily slows down time, all of which have limited functionality. It is unclear whether the glitch involved accessing custom moves that were incomplete or data not intended for use of custom moves. One of the variations of Mewtwo's glitched custom Confusion is very similar to the soul breaker glitch. It is speculated that these were unfinished custom specials and that DLC fighters were intended to have customs. While the glitch was removed by update 1.0.7, it was still possible to view replays containing these special moves in-game until the release of update 1.0.8.
• Mewtwo is the only veteran DLC character with a new voice actor, and the only character in SSB4 to speak in the Japanese version but not other regional versions.
• Mewtwo is the only DLC character to have been free to download through a special offer.
• Mewtwo is the only DLC character who does not share Equipment types with any other DLC character.
• Mewtwo's non-fighter trophy has different features than the design of it as a playable character, such as having smaller eyes, a shorter tail, and a lighter shade of purple for its midsection and tail. Mewtwo's playable model and trophy are modeled after the first Pokémon movie, differing slightly from Mewtwo's model in Pokémon X and Y, which has larger and rounder eyes than either of the two to match Mewtwo's official art by Ken Sugimori.
• Mewtwo's light weight in SSB4 contradicts its weight specified in the Pokédex, where it is listed as weighing 269 pounds; in SSB4, Mewtwo is only six units heavier than Jigglypuff despite it being more than twenty times heavier than the latter, which weighs only 12.1 pounds according to the Pokédex. This is seemingly due to its psychically-induced anti-gravity.
