Marceline Abadeer

"YOUR BLOOD IS MINE!!!"

- Marceline

Marceline Abadeer is a female vampire from Adventure Time.

First appearance
Marceline, the Vampire Queen first appeared in the episode "Evicted!" where she steals Finn and Jake's treefort because it belonged to her years ago. Finn and Jake then walk around and find a cave. When they find out the cave belongs to her, she and Finn clash. She then appears to have killed Jake, and Finn punches her hard and she reverts from her bat form and kisses him. She later gives him and Jake's house back. Now Marceline serves more of a friend of Finn in Adventure Time, but her mischievious nature makes her more of a anti-hero.

Return to the Nightosphere and Daddy's Little Monster
In Return to the Nightosphere, Marceline was some how turned evil and became ruler of the Nightosphere (unnoticeable before because she had a male voice and was shown with a monster head just like her dad, but was chopped off by Finn revealing herself). In Daddy's Little Monster it was revealed on Jake's camera phone that Marceline's Dad tricked her by giving her the Nightosphere amulet thinking it will grant wishes, but will turn anyone evil, including pure of heart heroes like Finn. Fallen into the powers of the amulet she throws Finn and Jake into jail and gives prisoners weird punishments, like bananas coming out of various body parts.
