Mew is a Psychic-type Mythical Pokémon introduced in Generation I.
It is not known to evolve into or from any other Pokémon.
Mew is notable for its unique ability to learn every Technical Machine, Technical Record, Hidden Machine, and Move Tutor move (except those exclusive to a particular Pokémon or group of Pokémon, such as Draco Meteor and Secret Sword).
Mew is the last Pokémon in the Kanto Pokédex in games prior to Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!
It is a member of the Mew duo along with Mewtwo.
As demonstrated by its behavior in the first and eighth Pokémon movies, it shows signs of intelligence, curiosity, shyness, playfulness, and even selflessness. Mew is incredibly adaptable, able to travel freely in the air or underwater. As seen in Pokémon Snap and the Super Smash Bros. series, it can create a green, yellow, or pink orb of energy around itself for protection, although only the pink orb is seen in the latter.
Reports found in Cinnabar Island's Pokémon Mansion note scientific expeditions that have sighted Mew in Guyana, South America, the place where it was first discovered. Since Mew can make itself invisible at will, very few people have knowingly seen it, leading some scientists to declare it extinct and most to assume it to be a mirage. It will only show itself to a person who is pure of heart.
Mew is the only known Pokémon capable of using the exclusive Z-Move Genesis Supernova.
