Ashachu

Ashachu (サトチュウ Satochuu) (alternatively spelled as Ashchu) is the name given to Ash by fans when he was accidentally transformed into a Pikachu by a magician by the name of Lily at the end of the episode Hocus Pokémon. Ash remained in this form until the beginning of the next episode As Clear as Crystal, where he was reverted into a human when the spell wore off.
