Ash

Ash is Marceline's immortal ex-boyfriend who appears in "Memory of a Memory." Marceline broke up with him because he sold Hambo, her favorite teddy bear, to a 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 for her. As Marceline wakes up, he and Marceline go to his house where he asks Marceline to make him dinner. She then finds out what happened by viewing Finn's memory of her memory of breaking up with him. Marceline comes out of Ash's house with Finn and they jump on him and kick him in his crotch, while Jake stretches into a giant sized foot and stomps on him.
