Adventure Time Theories

Marceline

Marceline is not a normal vampire. She drinks red instead of blood, has more shape-shifting abilities, and knows pyrokinesis, telekinesis and necromancy. She has also mentioned that she had demon heritage, so I conclude that some of her powers she would keep if she wasn’t a vampire.

Marceline’s relationship with her dad is less than ideal. This stems from various things, but I believe it is mostly from the fact she is still kind a teenager. Teenagers hate their parents.

Hudson Abadeer (Marceline’s dad) probably really liked Marceline’s mom, even though demons are probably incapable of love. This is probably why he is pretty lax with Marceline.

Marceline’s parents were divorced before her mom died. There is only one photo that is of their family together, and Marceline never mentions any memories of their parents together. It is probably also one of the reasons Marceline dislikes her dad.

Marceline had her fangs in Simon and Marcy, which probably means she was a vampire before the Mushroom War. Of course, those could be from her demon heritage. If so, then Marceline was probably bitten in her teens, and presumably by the Vampire King. That being said, she probably killed him, making her the Vampire Queen.

Marceline probably got her axe bass when she was little because in Betty, she plays with her bass way up her chest, much to Finn and Jake’s distain.

If Marceline was bit when she was a child, she probably can choose to stop aging, which is why she looks to be about 18.

Marceline is never seen doing any royal stuff. She appears once in a meeting of Ooo royalty in The Duke, but that’s it. Her title is probably honorary.

There is some speculation that Marceline is a self-proclaimed ruler and the only vampire. This is false because in Marceline and the Scream Queens one of the main characters is a vampire, and in the Adventure Time comic book there is mention of other vampires.
