Marceline

Name: Marceline Abadeer

Age: Approximately 1,000 years old (appears in her late teens/early 20s)

Species: Vampire/Demon hybrid

Personality: Marceline is a fun-loving and 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, which she crafted from her family's heirloom battle-axe. Despite being over a thousand years old, her appearance and personality is that of a late teenager.

Marceline is described as a wild rocker girl. Centuries of wandering the Land of Ooo have made her a fearless daredevil. She is a lover of all things exotic and still travels the land often. She has a mischievous personality and is rarely intimidated. Despite seeming evil at first, Marceline is a trickster at heart, and her "evil plans" often turn out to be nothing more than elaborate jokes. She is described by Finn as "a radical dame who likes to play games." She loves to play pranks on Finn and Jake. She also might sometimes have violent outbursts, and she can also be sentimental.

Marceline is capable of consuming the color red from an object she bites, while the object itself remains physically unharmed. Unlike traditional Western vampires, Marceline subsists not off blood, but rather the color red (including "low-grade" shades such as pink). Since she is only sated by the color itself, blood is appealing simply due to its hue (although she drinks blood sometimes too). When Marceline is deprived of red, she enters into a "feral" state, and will instinctively try to kill others and drink their blood. This rabid state subsides once Marceline consumes a sufficient amount of red. Like traditional Western vampires, she is vulnerable to sunlight and is capable of turning into a bat of varying size.

She was emotionally attached to her teddy bear Hambo, which was given to her by Simon Petrikov; after Ash sold it to the witch Maja, she was furious and broke up with him. It is easier for Marceline to express her feelings through music," but has trouble expressing them otherwise. She keeps a diary that she uses for inspiration for songs.

From her demonic father, Marceline inherited the power to absorb people's souls and minor control over fire. After absorbing the essence of several powerful vampires, Marceline gained several supernatural powers: the power to fly; the ability to turn invisible; the power to shape-shift; and the ability to rapidly heal. Marceline is immortal, youthful, and unaging as a vampire and she could live both forever and eternity. She can move things using her mind and can raise the undead to serve her. She can fire red energy beams from her arms that restrain people. She is ambidextrous, with ability to play bass with both hands. Marceline is a very talented musician and songwriter, and is proficient at singing and playing her basses.

It is worth noting that while vulnerable to sunlight, as is common in vampire lore, she does not burns right away. She's only vulnerable specifically to direct sunlight. Marceline is capable of unrestricted movement on a bright sunny day provided that she shields herself sufficiently, which she usually accomplishes with a combination of a parasol and a large sunhat, sometimes with the addition of full-length gloves to cover her arms. According to Marceline, moving around on a bright day still hurts mildly, comparable to scraping her knee, but she can bear it. Like typical vampires, Marceline cannot see her own reflection in a mirror. She also cannot digest syrup for some reason.

Relationships: -Finn: Though they were initially enemies, Finn and Marceline soon befriend one another. Marceline acts as a bully in her debut episode "Evicted!," she is impressed by Finn's brave aggression and defiance and chooses to kiss him on the cheek after they fight. Both Marceline and Finn share the same spark for adventure and love of danger and excitement. Marceline is very good friends with Finn and seems to trust him and be very comfortable with him. Marceline has made it clear she does not want to date Finn, and Finn doesn't want to date her either. Their relationship is a purely platonic friendship, more akin to an older sister and her little brother.

-Jake: Marceline cannot avoid scaring Jake when their two paths meet. Seeing his completely rational fear of vampires, Marceline often teases Jake and intentionally horrifies him when the chance is given. However, over time, Jake has somewhat overcome his fear, and considers Marceline a friend, a friend that may give him a heart attack one day. Marceline in turns, enjoys spending time with Finn and Jake, while still scaring Jake when she cans.

-Hunson Abadeer: Marceline used to hold a grudge against her father because he ate her fries, but the truth is that her grudge was born because she didn't think that her father cared about her or loved her, which was probably more hurtful than the fry stealing. After the two had a talk and he learned how she really felt, Marceline's father told her he loves her, and she told him she loves him too. They have reconciled for the time being, and now they have a classic teenage-daughter-to-father relationship.

-Bubblegum Princess: Marceline and Princess Bubblegum have a "friendly rivalry." Princess Bubblegum shows discomfort around Marceline and appears to disapprove of her creepy ways, while Marceline simply responds to this disapproval with mock affability, even teasing her with Bubblegum's first name of "Bonnibel" and inability to show someone a good time, like her, which causes even more dissaproval from Princess Bubblegum.

-Ash: Ash is Marceline's ex-boyfriend. They lived in Finn and Jake's Tree Fort before they moved in. Ash performed spells to impress Marceline and called her "Mar-Mar." Eventually Ash sold Hambo, a teddy bear, Marceline's beloved childhood toy, resulting in her becoming enraged and dumping him.

-Ice King: Marceline and the Ice King were close friends during the aftermath of the Mushroom War when he was still Simon Petrikov and he was the one who originally gave her Hambo. Marceline remembers her past connection with Simon, but the Ice King does not. Despite this though, Marceline sees him as an old father-figure of sorts. He's like an old grampa with dementia to her.

Appearance: Marceline has a slender, athletic build with has a slim, pale blue-gray complexion and long, flowing black hair. Her vampiric features include pointed fangs and sharp, claw-like nails. She has wide hips, a slim waist, a round, supple butt and large breasts.

Wardrobe: She wears mostly dark clothes with at least one red accessory, black dresses, shirts, hoodies, jackets, etc... But usually she'll wear a pair of jeans and a black top. Her most iconic item is her battle-axe bass, which doubles as both a weapon and a musical instrument.
