This Pokémon lives in dark places untouched by sunlight. When it appears before humans, it hides itself under a cloth that resembles a Pikachu.
Mimikyu was only recently identified as a Pokémon. Previously, people thought it was just a ghost wearing a cloth.

The tip of its forked tail quivers when it is predicting its opponent's next move.
It uses the fine hair that covers its body to sense air currents and predict its enemy's actions.
