Wamarigi is the evil version of Marigi. He was created when Wadaisy pushed Marigi into the Wa-Machine and changed the settings so that she could control him for her evil deeds. However Bowser just managed to destroy the machine in time. Marigi did come out as Wamarigi but he was not under Wadaisy's control. Wamarigi has the same powers as marigi. So he can turn people fat. Marigi turned Bowser into fat Bowser and he turned Wadaisy the pokemon snorlax.
