Brain Wiz

Brain Wizard first appeared in the episode "Wizard Battle." In the animatic, he left the battle when the Grand Master Wizard said that the prize was not an "open mouth kiss." His head looks like a brain. He was turned into a cat after saying he was going to leave. His cat form's furr is the same color as his brain head.

It was said by Frederator in a recap video on youtube for "Wizard Battle" that his name was "Brain Wiz." Although, this can just be a nickname.
