Ash (Adventure Time)

Ash is Marceline's immortal,[1] wizard ex-boyfriend who has his debut appearance in "Memory of a Memory." Marceline broke up with him because he sold Hambo, her favorite teddy bear, to Maja the Sky Witch in exchange for a new Cherry Blossom Wand. Disguised as a Rag Wizard, he used Finn and Jake to get a hold of Marceline's memory core containing her memory of breaking up with him so that he could destroy it, effectively making it like the break up never happened.
