Xatu is a Psychic/Flying pokemon introduced in Generation II. It evolves from Natu at level 25.
Xatu debuted in season 3 in the middle of the season. He was Elan Mak of the cast, so he was very relaxed and peaceful. Everything seemed to be going well for Xatu until Xatu was reminded about his dark past, and then he went rampant until Seaking calmed him down. Xatu and Seaking then quit the game in order to help Xatu revert to his normal self. Xatu didn't qualify for season 4.
