Mew is a pink, bipedalPokémonwithmammalianfeatures. It has a rounded, wide snout; triangular ears; and large, blue eyes. It has short arms with three-fingered paws and large hind paws with oval markings on the soles. Its tail is long and thin with an ovoid tip. Its fur is so fine and thin, it can only be seen under a microscope. Mew is said to have theDNAof every single Pokémon contained within its body, allowing Mew to learn and use any attack.
As demonstrated by its behavior in thefirstandeighth 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 inPokémon Snapand theSuper 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.
According to the radio drama,The Birth of Mewtwo, Mew was discovered byJessie's mother,Miyamoto, who registered its cry in Guayana Forest 20 years before the events ofGeneration I. It was worshiped for its protection by indigenous people who created a folk song in its honor and believed it appeared once a year with the rising sun. It wasn't rediscovered until 18 years after Miyamoto met Mew by sunrise on the peak of the highest mountain in a South American mountain range and fell.
Reportsfound inCinnabar Island'sPokémon Mansionnote scientific expeditions that have sighted Mew inGuyana, South America, the place where it was first discovered. Since Mew can make itself invisible at will, very few people haveknowingly 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 and has a strong desire to see it for themselves. Mew is shown in theanimeto be capable of splitting to transform into twoPokémonat the same time.
