|Introduced in||"Wizard Battle"|
Gentleman Wizard was one of the original competitors in the episode, "Wizard Battle." He, along with the Lady Wizard 1, Lady Wizard 2, and Brain Wiz, wanted to leave the battle after hearing the prize was a kiss from Princess Bubblegum. He and the others were turned into cats as a result, since no one is allowed to leave Wizard Battle until there is a victor.
He has purple skin, grey hair, and wears a pointed blue hat with flaps on either side of his head. He wears a yellow and blue superhero-like suit and a green cape. He has a symbol on his chest and cape that resembles a sideways crescent moon. When turned into a cat, his fur color is the same as his skin with a green spot similar to his cape. He also retains some of his facial features
