Marshall Lee

Marshall Lee (full name: Marshall Lee Abadeer the Vampire King ), is the gender-swapped version of Marceline, created by the original series designer, Natasha Allegri, who is featured in "Fionna and Cake." In the episode, he is seen attending Prince Gumball's Biennial Gumball Ball. Just like Fionna and others, Marshall Lee is from Ice King's imagination, although Marceline was telling his story in "Bad Little Boy". His skin appears to burn in sunlight in the episode "Bad Little Boy" like most vampires' and Marceline's. He plays a large role in "Bad Little Boy," attempting various ways to trick Fionna into admitting her love for him.

Abilities
Marshall Lee presumably has the same abilities as Marceline, since he was first seen floating. Some official artwork shows him eating the color red, just like Marceline, and sucks the pink from creme puff filling although he says he drinks blood in "Bad Little Boy". He can also sing and plays a bass. He can turn into a bat form, like Marceline, except he keeps his hair. Like Marceline, he can also raise the dead.

Appearance
Marshall Lee has a slim body, an average height, black hair, and light gray skin. He has a matching permanent bite mark like Marceline's. In "Fionna and Cake," he is seen wearing a red plaid shirt with gray stripes, dark blue jeans, and brownish-red and white sneakers. Like Marceline, his physical appearance is that of a typical late teenager.

Personality
Marshall Lee describes himself as a villain. He is rowdy, endangering others with his violent, 'friendly' rough-housing. He appears to have an interest in music like Marceline, as he's shown to rap and carry around and play an electric guitar, opposed to Marceline's bass guitar. He greeted Fionna with the sign of the horns, a very popular hand sign amongst heavy metal and rock fans. He also displays Marceline's love to mess with people with elaborate jokes, but goes to a further extent than his female counterpart and feels remorse quicker. Since Marceline is telling his story at this point, this might suggest the way she thinks of herself; as a villian, although Marshall Lee is argueably the more evil of the two. This also might suggest that Marceline wishes she could express her apologies better; she rarely apologizes to anyone. Marshall Lee also occasionally flirts with Fionna as seen in "Bad Little Boy."

Fionna
Marshall Lee is first seen interacting with Fionna in "Bad Little Boy." There, he is seen doing bad things to convince her that he's evil, while also trying to get her to admit that she loves him. He even goes as far to fake that he's dying, asking her to admit her love for him, and Fionna freaks out and tells him that in his last moments he should be serious. When he reveals that he was only faking, Fionna punches him then proceeds to do so again, laughing and crying at the same time.

Cake
Marshall often messes with Cake, but they seem to be on good terms. When Marshall Lee appeared to be hurt, Cake used her body to shield him from the sun. She was also relieved when Marshall revealed that he wasn't really dying even though Marshall just kidnapped her moments before.

Prince Gumball
Marshall Lee's relationship with Prince Gumball is similar to Marceline and Princess Bubblegum's rivalry.
