Mewtwo

Mewtwo (Japanese: ミュウツー Myuutsuu) is a -type Legendary Pokémon introduced in Generation I. It was created using Mew's DNA.

Physiology
Mewtwo is a bipedal feline-like Pokémon. Its appearance is loosely based on Mew, with a more of a mutated humanoid look in addition to its feline traits. Its body is purple and it has three fingers on each hand. Mewtwo projects a faint purple aura when at full power.

Forms
Mewtwo has an Anime/Manga exclusive form named Armored Mewtwo in the anime, and M2 Bind in the Manga. In the anime the form increases all of Mewtwo's Psychic abilities, and in the manga it allows Giovanni to control it. Mewtwo also has another form exclusive to the Pocket Monsters manga, where it takes on the DNA of a Clefairy, becoming a shorter, fatter and much stronger version of itself. Titling itself "Mewthree", it started its quest of cooking the best bacon ever until Satoshi managed to calm it down with his bacon. After going into a tantrum, screaming out "This isn't even my final form!", Mewthree split back into Clefairy and Mewtwo.

Characteristics
Mewtwo is highly adept at utilizing its Psychic powers, displaying telekinesis and telepathy as well. It utilizes its telepathy to communicate with humans and translate the Pokémon language. It uses its telekinesis to fly, block special abilities, and expunge people's recollections as optically discerned in Mewtwo Strikes Back.

Behavior
As evidence of its immense power, Mewtwo is by far one of the most domineering Pokémon in the series. It's power is so great to the point where it can endure immense toruture in Mewtwo Returns, and teleport a lake miles long underground! Proven in the first Pokémon Movie, Mewtwo holds a large degree of pride in its personality. In fact, it general nature is so complex that it borderlines that of human levels, with itself capable of learning and evolving just to get the upper hand in battle. Indeed, Mewtwo's title of "The World's Most Powerful Pokémon" shouldn't be undermined.

Evolution
Mewtwo does not evolve. However, it can Mega Evolve with the use of a Mewtwonite X or a Mewtwonite Y.
