He was a Wizard who was Marceline's immortal ex-boyfriend. The reason for the break up was because he sold her teddy bear Hambo to a witch so he could get a new Cherry Blossom Wand. He later disguises himself as the Rag Wizard, and dopes Finn and Jake into helping him obtain the memory of Marceline dumping him in the pretense that she put herself in a sleeping spell, and would remain asleep for eternity if they didn't get the memory. When they return the memory to him, he destroys it, so that Marceline wouldn't remember dumping him. He then goes into Marceline's house and asks for dinner. He later returns when Marceline's memory comes back to her, and of the bat asks her for a sandwich, not caring in the slightest for trading her teddy bear in exchange for the wand. Finn, Jake, and Marceli
