Ashachu is the terrible combination of Ash Ketchem and a Pikachu. In one of the Pokemon Anime episodes, some "Pokemon magician" named Lily was stalking Ash's Gang and jumped in front of them. After torturing Misty alot, she turned Ash into a Pikachu as he was acting like an idiot the whole entire episode (His actions went from throwing axes at everything to clipping his toenails, which landed in a cauldron of EVIL making it blow up). As he was a Pikachu he got beaten up by his own Pokemon for treating them horribly. Despite this, the spell's effect worn off, and Ash became a human again.
