'''Mewtwo''' ({{ja|ミュウツー|Myūtsū}}, ''Mewtwo'') is the Genetic Pokémon from the {{uv|Pokémon}} series. It debuted in the series' [[bulbapedia:Generation I|first generation]], and is present as a playable character in ''[[Super Smash Bros. Melee]]'', ''[[Super Smash Bros. 4]]'', and ''[[Super Smash Bros. Ultimate]]''.

==Origin==
[[File:MewtwoArtworkRG.png|thumb|left|Official artwork of Mewtwo from ''Pokémon Red'' and ''Blue Versions''.]]
Mewtwo is a Psychic-type Pokémon that debuted in {{s|bulbapedia|Generation I}}, and is categorized within the Pokédex at #150 as the "Genetic Pokémon".<ref name=Dex>[https://www.pokemon.com/us/pokedex/mewtwo Mewtwo | Pokédex]</ref> Unlike the overwhelming majority of Pokémon, Mewtwo was [[bulbapedia:Artificial Pokémon|artificially created]]: a team of scientists performed genetic recombination on a sample of DNA derived from the {{s|bulbapedia|Mythical Pokémon}} [[Mew]]<ref name=Dex/> in order to create the most powerful Pokémon in existence. Its creation is documented in [[bulbapedia:Pokémon Mansion journals|a researcher's journals]] scattered across [[bulbapedia:Pokémon Mansion (Kanto)|an abandoned mansion]] on {{s|bulbapedia|Cinnabar Island}}.

However, this process resulted in Mewtwo's appearance and mentality drastically differing from Mew's. Despite being a feline with embryonic features like Mew, it has a large, humanoid physique with a gray and purple coloration, instead of the pink, petite appearance of its genetic relative. Mewtwo also lacks Mew's capability to learn every {{s|bulbapedia|Technical Machine}}, {{s|bulbapedia|Hidden Machine}}, and {{s|bulbapedia|Move Tutor}} move, but its modified genome results in its base {{s|bulbapedia|statistic}} total noticeably exceeding Mew's.

Although Mewtwo is reclusive like Mew, this is the only personality trait they share: due to being created solely for battle, Mewtwo has a tendency to be vicious and, upon encountering an opponent, fights savagely while thinking only of defeating them. In comparison, Mew has a gentle temperament and willingness to reveal itself to the pure of heart. After violently escaping captivity, Mewtwo decided to seclude itself from civilization; most notably, it has been seen residing in the deepest depths of {{s|bulbapedia|Kanto}}'s {{s|bulbapedia|Cerulean Cave}}, a [[bulbapedia:Unknown Dungeon (Kalos)|small cave]] within {{s|bulbapedia|Kalos}}' {{s|bulbapedia|Pokémon Village}}, and a [[bulbapedia:Ultra Space Wilds#Rocky World|craggy, barren alternate dimension]] that is accessible via {{s|bulbapedia|Ultra Space}}.

Due to being an immensely powerful genetic relative of a Mythical Pokémon, Mewtwo has the status of a {{s|bulbapedia|Legendary Pokémon}} in spite of its man-made origin. In-game, Mewtwo was designed to be the final Pokémon of Generation I, and has traits that highlight its status as such: not only is it difficult to find and capture, it belongs to the notoriously powerful Psychic type and sports the highest base stat total in the entire game, with especially high Special and Speed stats. Due to being arguably the strongest Pokémon in existence at the time, as well as its leading role in the franchise's [[bulbapedia:M01|first movie]], Mewtwo quickly garnered a good degree of fame and popularity among the ''Pokémon'' fanbase. Since then, Mewtwo's power has diminished due to various mechanical changes, although owing to its Legendary Pokémon status, it still remains significantly stronger than most common Pokémon.

After receiving {{iw|bulbapedia|Psystrike|move}} as a {{s|bulbapedia|signature move}} in {{s|bulbapedia|Generation V}}, Mewtwo's prominence underwent a resurgence in {{s|bulbapedia|Generation VI}}, with it being among the initial handful of Pokémon to gain access to {{s|bulbapedia|Mega Evolution}}. Unlike most Pokémon who can Mega Evolve, it has two Mega Evolutions, a trait shared with [[Charizard]]. In Mewtwo's case, it will Mega Evolve into the larger and bulkier Mega Mewtwo X while holding Mewtwonite X, which also changes it into a Psychic/Fighting-type.<ref name=Dex/> Conversely, it will Mega Evolve into the smaller and lighter Mega Mewtwo Y while holding Mewtwonite Y.<ref name=Dex/>

In the ''Pokémon'' anime and movies, {{iw|bulbapedia|Mewtwo|original series}} is depicted as having been cloned from an eyelash of Mew and created at {{s|bulbapedia|Team Rocket}}'s behest. Given a more [[bulbapedia:The Uncut Story of Mewtwo's Origin|sympathetic backstory]] than in the games, Mewtwo befriends a group of clones as a child, but the cloning process results in their premature deaths—with the exception of Mewtwo itself, due to having Mew's eternal life force. The trauma of losing its friends, coupled with being dismissed as a science experiment by its creators, causes Mewtwo to develop hatred towards humans and Pokémon subservient to humans. Thus, Mewtwo sets out to prove itself superior to natural lifeforms by creating an army of cloned Pokémon created from the genetic source material of various [[Pokémon trainer]]s' Pokémon.

However, Mewtwo has a change of heart after witnessing {{s|bulbapedia|Ash Ketchum}} sacrifice himself to stop a battle between its clone army and their originals; Mewtwo subsequently realizes that life is defined by one's actions instead of their origins. To this end, it begins to protect its fellow clones after whisking them away to {{s|bulbapedia|Johto}}'s {{s|bulbapedia|Mount Quena}}, a mountain that is virtually inaccessible by humans. After stopping Team Rocket's attempt at recapturing it and subsequently erasing their memories of its existence, Mewtwo decides to travel the world in order to avoid detection and find a purpose in its life, whereas its fellow clones decide to live peacefully among natural Pokémon in the wild. This Mewtwo reappears in an episode of ''Pokémon Journeys''.

Despite the species' one-of-a-kind nature originally, other Mewtwo have appeared in the {{s|bulbapedia|core series}} and across the various Pokémon continuities ever since. Two other Mewtwo have fully-voiced appearances: [[bulbapedia:Mewtwo (Best Wishes series)|one]] in [[bulbapedia:M16|the sixteenth movie]] that is capable of undergoing Mega Evolution, and [[bulbapedia:Mewtwo (Detective Pikachu)|one]] in both the ''{{iw|bulbapedia|Detective Pikachu|game}}'' spin-off game and the [[bulbapedia:Detective Pikachu (movie)|live-action movie of the same name]].

The gender of Mewtwo is Unknown<ref name=Gender />, although this is not depicted consistently in other media. In the anime, the telepathically-generated voice for the first Mewtwo is male (which is reflected in the ''Super Smash Bros.'' series), whereas the second Mewtwo featured in the sixteenth movie has a feminine voice. In comparison, the ''Detective Pikachu'' film's Mewtwo possesses an artificial, androgynous voice, but is referred to with male pronouns nonetheless.

==In ''[[Super Smash Bros.]]''==
Mewtwo does not appear in ''Super Smash Bros.'' in any capacity. However, according to a page on ''[[Smabura-Ken]]'' (the game's Japanese site), it was planned for inclusion in the roster as a playable fighter, but was removed from the game along with [[Bowser]] and [[King Dedede]] for unknown reasons.

In an official poll held on ''Smabura-Ken'' regarding characters for a potential sequel, Mewtwo placed sixth with 35 votes; it was tied with James Bond from ''[[GoldenEye (universe)|GoldenEye 007]]''.<ref>[http://www.nintendo.co.jp/n01/n64/software/nus_p_nalj/smash/PostResult2.html Super Smash Bros. questionnaire]</ref>

==In ''[[Super Smash Bros. Melee]]''==
===As a playable character===
{{Main|Mewtwo (SSBM)}}
[[File:Mewtwo SSBM.jpg|150px|thumb|Mewtwo, as it appears in ''Super Smash Bros. Melee''.]]
Mewtwo made its ''Super Smash Bros.'' series debut as an unlockable character in ''Super Smash Bros. Melee''. It can be unlocked after playing 20 cumulative hours of [[Versus Mode]] matches (5 hours for 4 players) or playing 700 Versus Mode matches.<ref name=SG>[https://www.sourcegaming.info/2016/01/15/melee-mewtwo/ News Flash! Super Smash Bros. Dojo: Mewtwo - Source Gaming]</ref>

Mewtwo is very [[floaty]] and possesses a decent combo game, a very good [[wavedash]] and grab game, above-average dodges, a strong projectile in [[Shadow Ball]], and one of the best recoveries in [[Teleport]]. Mewtwo also possesses a [[reflection]]-capable move in [[Confusion]], while [[Disable]] [[stun]]s any close-range opponent that directly faces Mewtwo.<ref name=SG/> On the other hand, Mewtwo has a flawed combination of large size and light weight; this not only results in it being an easy target to hit and combo, but also especially easy to KO despite its recovery and defensive prowess.<ref name=SG/> Mewtwo also has general awkwardness in its mobility and moveset, the latter of which is burdened with minimal utility and a small number of KOing options.

As a result of its weaknesses and flaws outweighing its strengths, Mewtwo infamously sat in the bottom-tier of ''Melee''{{'}}s [[tier list]] for most of the game's lifespan, to the point that it was even considered the worst character in the entire game at several points in ''Melee''{{'}}s lifespan. However, the efforts of {{Sm|Taj}} resulted in Mewtwo being reassessed as a low-tier character; this has been reflected with its current ranking of 20th out of 26 on the tier list, placing it in the D tier.

===Trophies===
{{main|List of SSBM trophies (Pokémon series)}}
As a playable character, Mewtwo has three trophies - a main trophy acquired by clearing {{SSBM|Classic Mode}} with Mewtwo on any difficulty, and the two Smash trophies are by clearing {{SSBM|Adventure Mode}} and [[All-Star Mode]], respectively.

{{clrl}}

==In ''[[Super Smash Bros. Brawl]]''==
Mewtwo did not return in ''Super Smash Bros. Brawl'' as a playable character, despite not being a [[clone]] like the other cut characters. Although Mewtwo was unpopular among ''Melee''{{'}}s competitive community, its departure nevertheless resulted in a significant amount of fan outcry, as the majority of players saw it as an unjustified cut. ''Brawl'' also introduced {{SSBB|Lucario}}, a fellow ''Pokémon'' series fighter, who was widely perceived by fans as being a replacement for Mewtwo around the time of ''Brawl's'' release; however, other than their similar neutral specials [[Shadow Ball]] and [[Aura Sphere]], their movesets are vastly different.

===Unfinished data===
{{main|Beta elements (SSBB)#Fighters}}
While Mewtwo does not appear as a playable character in ''Brawl'', there are several empty files on the game disc bearing its name. These include a graphic effects file (<code>ef_mewtwo.pac</code><ref>[http://www.destructoid.com/elephant/photo-m.phtml?post_key=68272&photo_key=29687 Rumortoid: A full list of the files found on Smash Bros. Brawl disk? (UPDATE)]</ref>), a [[Music_(SSBB)#Removed_tracks|victory theme]] (<code>snd_bgm_Z38_MYU2</code><ref>[http://www.smashboards.com/showpost.php?p=10920499&postcount=133 Brawl Beta Elements List-First Post Majorly Updated 7/26/10 | Page 4]</ref>), and a [[Wii Remote selection sound]] (which no other cut character has). While it is possible that some of these files are leftover data imported from ''Melee'' for referential purposes, the prevailing theory is that Mewtwo was planned to be playable, but ended up being cut. As Mewtwo has the most unused content of any scrapped character, it can be assumed that Mewtwo was a late cut to ''Brawl''{{'}}s roster.

===Trophy===
{{main|List of SSBB trophies (Pokémon series)}}
Mewtwo appears in ''Brawl'' as a collectible trophy, obtained by completing [[All-Star Mode]] on Intense difficulty. The trophy describes Mewtwo's appearance in the ''Pokémon'' games, but makes no reference whatsoever to its appearance in ''Melee''.

{{Trophy

==In ''[[Super Smash Bros. 4]]''==
===As a playable character===
{{Main|Mewtwo (SSB4)}}
[[File:Mewtwo SSB4.png|thumb|200px|Mewtwo, as it appears in ''Super Smash Bros. 4''.]]
During development of the game, an appearance of Mewtwo's {{s|bulbapedia|Mega Evolution}} was reportedly considered by [[Masahiro Sakurai]]. During the [[bulbapedia:Pokémon X and Y|''Pokémon X'' and ''Y'']] Developer Roundtable at [[E3 2013]], an audience member asked if developers wanted to see [[bulbapedia:Mega Evolution|Mega Mewtwo]] in the next ''Super Smash Bros.'' game. While the developers stated that they had nothing to report about the question, Sakurai, who was in the audience at the time, reportedly said "We are thinking about it."<ref>[http://www.nintendoworldreport.com/news/34700 Sakurai Considering Mewtwo for Next Smash Bros. Games]</ref>

Despite this, Mewtwo did not initially make the final cut of the game as a playable character, returning only as a collectible trophy. Mega Mewtwo X and Mega Mewtwo Y also appear together as a singular trophy in {{forwiiu}}.

Mewtwo was later announced in the [[Nintendo Direct#Super Smash Bros. for Wii U: 50-Fact Extravaganza|''Super Smash Bros. for Wii U:'' 50-Fact Extravaganza]] as a playable character, becoming the first fighter in ''Super Smash Bros.'' history to be made available as [[downloadable content]].

Consumers who registered both {{for3ds}} and {{forwiiu}} on Club Nintendo before March 31, 2015 could download it for free as of April 15th, while others were able to purchase it beginning on April 28th. Its moveset is mostly unchanged from ''Melee'', aside from the addition of its own [[Psystrike|Final Smash]], consisting of Mega Evolving into Mega Mewtwo Y before performing its {{s|bulbapedia|signature move}}, {{iw|bulbapedia|Psystrike|move}}.

Upon its return to the series, Mewtwo was poorly regarded by the competitive scene, as its already light [[weight]] was lowered further and its already large hurtbox became slightly taller. However, Mewtwo did see improvements to [[Confusion]] and [[Disable]], two of its most arguably least used moves: the former now functions as a traditional [[reflector]], while the latter's [[stun]] effect has a longer duration.

However, Mewtwo underwent a considerable turning point thanks to game updates. Update [[1.1.3]] increased Mewtwo's grounded and aerial speeds, as well as improving its already potent forward smash and aerial attacks. Although update [[1.1.5]] provided very few changes, they were effective regardless: Mewtwo's weight was marginally increased, its already fast dashing speed was increased to the point of becoming the seventh fastest in the game, and both its up smash and neutral aerial were made safer thanks to adjustments to their ending lag and hitbox sizes, respectively.

As a result of these very substantial buffs, opinions on Mewtwo drastically improved, as it has managed to earn some noteworthy representation and consistently achieves high placings at all levels of play. Thanks to this newfound success, Mewtwo is currently ranked 10th out of 54 on the [[tier list]], placing it in the A tier and assessing it as a top-tier character.

Mewtwo returns as an unlockable character in ''Super Smash Bros. Ultimate''. Much like in ''Melee'', it is one of the very last characters to be unlocked, as all three of its unlock methods (Smash battles, {{SSBU|Fox}}'s {{SSBU|Classic Mode}} unlock tree, and [[World of Light]]) designate it as one of the last characters encountered.

==Trivia==
*Like [[Charizard]] in ''[[Super Smash Bros. 4]]'' and [[Lucario]], Mewtwo draws inspiration from a particular member of its species depicted in the ''Pokémon'' anime. In Mewtwo's case, it is based on the {{iw|bulbapedia|Mewtwo|original series}} from ''Pokémon: The First Movie: Mewtwo Strikes Back'' and the TV special ''Mewtwo Returns'', although it also makes some references to the {{iw|bulbapedia|Mewtwo|Best Wishes series}} from ''Mewtwo — Prologue to Awakening'' and ''Genesect and the Legend Awakened'':
**It is voiced by Masachika Ichimura in ''[[Super Smash Bros. Melee]]'', the Japanese voice actor for the first Mewtwo, which is emulated by Keiji Fujiwara in ''SSB4''. Its Japanese quotes in both games have it boast about its power and question its existence, much like the first Mewtwo did on several occasions. The quotes were not dubbed in other languages; they were swapped out with language-neutral voice clips in the non-Japanese versions. In ''Ultimate'', the same thing would happen to some of [[Hero]]'s voice clips.
**It can use {{iw|bulbapedia|Shadow Ball|move}} like the first Mewtwo. Its presence in Mewtwo's moveset is notable, as it appeared in the first movie before it even appeared in the {{s|bulbapedia|core series}}.
**It can undergo {{s|bulbapedia|Mega Evolution}} into Mega Mewtwo Y like the second Mewtwo.
**It can use its signature move, {{iw|bulbapedia|Psystrike|move}}, like the second Mewtwo. However, Psystrike has a unique design and functions differently in the ''Super Smash Bros.'' series compared to how it looks and functions in the games and the anime.
***Incidentally, Psystrike's animation was updated in {{s|bulbapedia|Generation VII}} to resemble its depiction in the ''Super Smash Bros.'' series.
**Its character introduction tagline in ''SSB4'', "Mewtwo Strikes Back!", references ''The First Movie''{{'}}s full English title.
**Its [[Boxing Ring#Character titles|Boxing Ring character title]], "A Legend Reawakens", references ''Genesect and the Legend Awakened''{{'}}s English title.
*Mewtwo is the only playable {{s|bulbapedia|Legendary Pokémon}} in the ''Super Smash Bros.'' series. It is also the only playable Pokémon without evolutionary relatives and whose gender is unknown.
**Despite this, it does possess a form of kinship with another Pokémon. In Mewtwo's case, it is one half of the {{s|bulbapedia|Mew duo}}.
*Mewtwo's status as a [[Weight|lightweight]] in the ''Super Smash Bros.'' series contradicts its weight in the {{s|bulbapedia|Pokédex}}, where it is listed as weighing 269 pounds/122 kg. This is seemingly attributed to its telekinetically-induced anti-gravity. A similar case applies to [[Rosalina]].
*Mewtwo and Lucario are the only playable Pokémon whose on-screen appearances do not involve them emerging from a {{s|bulbapedia|Poké Ball}}.
*In all its appearances, Mewtwo only holds one item with its hands. In this case, it is the [[Parasol]] while descending. Otherwise, it uses telekinesis to make items float in front of it.
*By default, Mewtwo has the fastest air speed of every ''Melee'' newcomer.
**Mewtwo also has the 3rd fastest air speed to [[Jigglypuff]] and [[Yoshi]], despite having the same air speed as the latter in ''Melee'', thus also making it the second fastest ''Pokémon'' character in every ''Smash'' game where it is playable.
*Mewtwo is the only character cut in the transaction from ''Melee'' to ''Brawl'' that is not a moveset<!--specified here to avoid potential misunderstanding, since Mewtwo is a literal clone in lore--> [[clone]] of another character.
*Mewtwo is the only playable character to be known to be planned for more than one installment without being playable, those being [[Super Smash Bros.|the original ''Super Smash Bros.'']] and ''Brawl''.
