Marceline is a fun-loving & playful 1,000-year-old vampire queen. Unlike a traditional vampire, Marceline does not need to drink blood to survive; rather, she consumes the color red, or other similar tints. Marceline is also an avid musician who plays an electric bass guitar, which she crafted from her family's heirloom battle-axe. During her time, she has evolved into a 'fearless daredevil', turning her into a bit of a trickster. Without food, she becomes vicious and sinister, blood.
