*"Jake, I don't wanna hurt you. But you should know things get crazy when I'm hungry.*" - Marceline

## Profile

### Identity

Berserker's true identity is **Marceline**, a fun-loving 1,000-year-old vampire queen. Unlike a traditional vampire, Marceline does not need to drink blood to survive; rather, she eats the color red. Marceline is also an avid musician who plays an electric bass that she made from her family's heirloom battle-axe. She is currently in a romantic relationship with Princess Bubblegum, something revealed to the audience during the episode episode "Come Along With Me".

### Personality

Having spent centuries traversing the Land of Ooo, she has evolved into a "fearless daredevil", and her fondness for mischief has turned her into something of a trickster. Consequently, in her first role, Marceline functions as the antagonist of the story, forcing Finn and Jake from their home. However, she eventually becomes their close friend once Finn recognizes that she is "a radical dame who likes to play games".

It is implied that some of her more malevolent traits are solely based on her vampire instincts. In "Red Starved", Marceline slowly becomes vicious and sinister after having been deprived of food, trying to tempt Jake so that she could eat him. In "Vamps About", Marceline was fine with Peppermint Butler creating weapons meant to kill her as a contingency, stating that she could have snapped and killed everyone at any given time.

She can also be sentimental. She was very emotionally attached to her teddy bear Hambo, which was given to her by Simon Petrikov; after Ash sold it to Maja, she was furious and broke up with him. Later, Princess Bubblegum got Hambo back in the episode "Sky Witch".

Marceline seems to be very emotional. For example, in "What Was Missing", she seemed to be more aggressive towards Princess Bubblegum than she usually is. She is also very independent, and in early episodes would often act without concern for Finn or his friends. It is easier for Marceline to express her feelings through music, as seen in the "Fry Song" and "I'm Just Your Problem," but has trouble expressing them otherwise. She keeps a diary that she uses for inspiration for songs as seen in "Marceline's Closet." When Marceline read the lyrics to "Remember You", the song that Simon Petrikov wrote for her, she began to cry.

Near the end of "The Dark Cloud", her personality changed slightly. Marceline had learned how to be more mature which is proved by her saying that she will be able to hang out with Princess Bubblegum "forever". She also said the learned how to be more empathetic to others too. Yet, it is still unknown if she got over her emptiness in the end.

## Abilities

From her demonic father, Marceline inherited the power to absorb people's souls and minor control over fire as shown in evicted's first look at the fire kingdom and her use on candles. It was also implied by her Farmworld counterpart that her half-demon nature extended her natural lifespan, as Farmworld Marceline was able to survive for at least 1000 years, albeit old and withered.

After absorbing the essence of several powerful vampires, Marceline gained several supernatural powers. From The Fool she gained the power to fly; from The Empress the ability to turn invisible; from The Hierophant she gained the power to shape-shift (e.g. taking the form of a bat, a wolf, a reptilian creature, a large tentacled monster and she can even copy the form of other creatures if she has time to study them); and from The Moon, the ability to rapidly heal.

Marceline is immortal and unaging as a vampire.

She lit up all the candles in Finn and Jake's house with a wave of her fingers.

She can move things using her mind. She probably obtained this power from Vampire King, but this hasn't been confirmed.

Marceline can raise the undead to serve her.

As a result of absorbing the Vampire King's dark cloud half, she can now communicate with a miniature mental projection of him. During the turmoil of the Gum War, Marceline was able to releases the vampiric essence she absorbed from the Vampire King, transforming into a similar black, cloud-like form. In this state she was powerful enough to defeat one of the creatures created by GOLB.

According to Ward, she is ambidextrous, which explains her ability to play bass with both hands.

Marceline is capable of consuming color from any object she bites, while the object itself remains physically unharmed. Her preference is objects that are red in color. If she doesn’t consume enough red-colored objects, Marceline goes into "feral mode", a state in which she becomes ravenous out of hunger. This rabid state subsides once Marceline consumes a sufficient amount of red. She has also revealed that she cannot digest syrup.

She has typical vampiric weaknesses. It is worth noting that while vulnerable to sunlight, as is common in vampire lore, she does not dissolve right away. The nuance to this in the Adventure Time world is that vampires are 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.

### Noble Phantasm

#### **Nocturnal Vampire**

Her NP has the ability to shape-shift into numerous monstrous forms, including a bat, a wolf, a reptilian creature, and a large tentacled monster. She appears to be able to preserve her clothing, even after changing into large forms that would cause it to break: in many appearances, the clothing disappears until she returns to her humanoid form, whereas in "Sky Witch", she performs numerous transformations while still wearing her outfit. She obtained this power from The Hierophant.
