Marceline Abadeer

"YOUR BLOOD IS MINE!!!"

- Marceline

Marceline Abadeer is a female, half-demon/half-vampire. She is one of the main characters from the Cartoon Network show Adventure Time and serves as the secondary antagonist of season 1, and a supporting anti-hero and eventual protagonist for the rest of the series.

She was voiced by singer/actress Olivia Olson, who is known for voicing Vanessa Doofenshmirtz.

Background
Marceline is over a thousand years old, as she stated in "Evicted!" and "Daddy's Little Monster." In the episode, "Memory of a Memory", she is a young girl playing by herself in the ruins of a city, presumably during or after The Great Mushroom War. Later on, in the episodes "Simon and Marcy" and "I Remember You" she is showing with The Ice King (Simon Petrikov) who gave Marceline her doll Hambo and acted like as a father-figure to the girl. In the episode "Memory of a Memory", she is seen as a teenager who sees her father, eating her fries in the ruins of an old diner. This damages their relationship, and Marceline would later sing about this event in her "Fry Song." The first memory she is in chronologically, is seen as a vampire, is where she moved into the Tree Fort with her boyfriend Ash. She would later dump him after he sold Hambo to a witch.

Appearances
Marceline, the Vampire Queen first appeared in the episode "Evicted!". In the episode, she kicks Finn and Jake's out of their tree-fort 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.

Marceline appears as a villain again in the episode "Henchman." In the episode, it is revealed that she has an old man henchman and forces him to do many cruel and embarrassing things. Finn, out of pity for the old man, agrees to be Marceline's new henchman. She then has the young adventurer do things like hold down a man so she drink his blood, raise and army of the undead, and sack the nut castle. Yet during these events, Finn sees that Marceline seems to be only having fun with him, for their deeds are actually harmless or even good. She only eats the red from the mans bow tie, turning it white (which he finds beautiful), and she was only preforming at the Duke of Nuts second son's birthday party.

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.

In the episode "Red Starved", she, along with Finn and Jake, go to an ancient ruin to look for the Spoon of Prosperity. When Jake eats the red erasers she brought along for food, Marceline reveals that if she goes to long with eating, she will go feral and kill everyone around her. She tries to kill Jake, but Princess Bubblegum arives and lets Marceline eat some of her pink color ("a low-grade red") and the vampire queen returns to normal.

This turns the objects a white/grey color. In "Evicted!" she says she "sometimes" eats blood, but she has never been seen doing it yet. Another thing to note is she says she gets lucid dreams when she eats tomatoes.
