Marceline the Vampire Queen (Full name: Marceline Abadeer) is a radical dame who likes to play music. She is the bass playing, lyrics making, and super rocking goddess of Vampires. She is over a thousand years old and hangs with Finn (when she wants to jam with him). She can get a little monster-like (mostly to Jake), but we all know she is one of the most loved character on the show. She is first seen in the episode "Evicted!," where Finn first saw her out the window. She then sprang down from the ceiling and sat down on the couch with Finn and Jake.
Both being terrified when seeing her, she explained herself, telling them her adventures and showing the items she has. But she explains the the house they live in is rightfully hers and kicks both Finn and Jake out. During the House Hunting Song in the same episode, she was seen playing BMO, which is odd, meaning that she did not kick BMO out. After Finn and Jake found a new home and throws a party, she shows up. She comes in happily but Finn is angered that she came. Marceline proves that the cave Finn and Jake took as their new home is also hers. Finn and Jake had a dispute with her which lead to a battle. She angrily changed into a large bat monster.
As of "Sky Witch", Marceline is reunited with Hambo.
