"Of all histroy's monsters,you are far the most evil thing I've encountered. Offer your soul to me dark one!"

- Marceline's Dad to Gunter Marceline's Dad is the father of marceline and the antagonist of the Adventure time episode "It came from the Nightosphere"

He is an Demon that was sealed away in the Nightosphere until Finn freed him in an attempt to bring Marceline and her father back together. Marceline was not happy to see him, as he feels as he does'nt care about her as well as that he stole some of her fries during a meal at one point in the past. He stormed over Ooo, sucking the soul of every living thing he met, except for the Ice King and Gunther the penguin, whom he thought was much more evil then him. When he met Marceline, he apologized for stealing her fries and reminds her that he still loves her. At that point Finn sealed him away again on the Nightosphere and frees all the souls he stole, leaving Marceline upest at him for not leaving her enough time to fully bound with him.
