Brain Wizard is a very minor character in the episode "Wizard Battle." He tried to drop out of the battle with Lady Wizard 1, Gentleman Wizard, and Lady Wizard 2 when they learned that the prize was a kiss from Princess Bubblegum (but was not an open mouth kiss), and were turned into cats by the Grand Master Wizard for denying the tournament.
Appearance[]
He wears a purple and white suit with purple gloves, a purple mask and a purple cape. His eyes are yellow and his head is a brain.
