Marshall Lee (full name: Marshall Lee the Vampire King[2]) is the gender-swapped version of Marceline, created by the original series designer, Natasha Allegri. He makes his first appearance in the episode "Fionna and Cake."

Like Fionna and other gender-swapped characters, Marshall Lee is from Ice King's imagination, however, Marceline was telling his story in the episode "Bad Little Boy." His first and only major role was in "Bad Little Boy," where he attempted to make Fionna confess her romantic attraction to him in many ways.


Marshall Lee is presumed to have the same abilities as Marceline, as, he is seen levitating, along with being able to turn into a bat. Some official artwork shows him eating the colour red, like Marceline does, and consumes the pink from creme puff filling. In "Bad Little Boy", he mentions "drinking the red from your heart in one sitting", although, this could have been a fib. He can also sing, however, raps more, and is shown to play a guitar.[3] He can turn into a bat form, like Marceline, with the difference being that he keeps his hair. Like Marceline, he can also raise the dead and control them. Marshall Lee also appears to have the same rapid healing that Marceline has, as, when the sun started to burn him, the burn vanished shortly after Cake used her body and blocked it from touching him. He is shown to have a resistance to cold weather, as demonstrated in "Sugary Shorts".


Marshall Lee is taller compared to most of the other characters, standing at what appears to be around 5'11. He has messy black hair, and two sharp canine teeth like Marceline's. Like Marceline, he has a permanent bite mark on his neck, and pointed ears. Marshall Lee commonly wears a buttoned, grey striped red plaid, dark blue jeans with turn-ups, and brownish-red and white sneakers. His sneakers seem to be Converse. Like Marceline, his physical appearance is that of a typical late teenager or a young adult.


Marshall Lee describes himself as a villain, fitting the part as he is rowdy, and endangers 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. His behavior towards Fionna mirrors that of Marceline towards Finn in "Evicted!," taking Cake away from Fionna for fun (and in Marshall's case at least, for her attention). However, he seems to feel remorse more quickly than her. This also might suggest that Marceline wishes she could express remorse better; she rarely apologizes to anyone. Since Marceline is telling the story at this point, this might suggest the way she thinks of herself; as a villain, although Marshall Lee is arguably the more evil of the two. Marshall seems to be more violent than Marceline, saying that he "kills people every night," although this may be an exaggeration.

Marshall Lee and Fionna are shown to be very good friends. It is unknown whether Marshall Lee has romantic feelings for Fionna, despite both of their ages being vastly different, although, in "Bad Little Boy," he says to her, "Why don't you just admit it? You're in love with me." Fionna also states that he flirts with her constantly. He also called her 'baby' in his song "Good Little Girl." Marshall Lee is first seen briefly in the episode "Fionna and Cake," when he notices Fionna entering Prince Gumball's party and flashes her the sign of the horns, sticking his tongue out.

Similar to Finn and Marceline's relationship, Marshall Lee likes to mess with Fionna's head. In "Bad Little Boy" (the second episode featuring Ice King's fan-fictions), he zooms into her house and steals the pastries Prince Gumball had brought for Fionna, leading her outside to investigate a noise that is probably him landing on her roof. When Fionna finds him on the roof playing his guitar, he looks up and smoothly says, "Oh. Hey, Fionna." Fionna responds by smiling and says his name in a gleeful way. He asks her to go to Lumpy Space Prince's Party, but she is uncertain at first of whether she should go, presumably because she has Prince Gumball over for company and would have to ditch him to go. Marshall transforms to bat form and reaches out his hand for hers, saying he knows she will give in. She smiles reluctantly and takes his hand before being flown into the forest. There at the party, he is seen doing obnoxious things and teasing her, all the while trying to convince her that he is evil. He even goes as far to fake a fatal injury and tell her to admit her love for him. While doing this, Fionna yells out and tells him that in his last moments he should be serious. She mentions that he likes to flirt with her and seems to think it is funny. When he sees her emotional and crying and reveals that he was only faking, Fionna angrily punches him, then chases him while he protests and proceeds to hit him again off-screen, laughing maniacally.


Marshall often messes with Cake, but they seem to be on good terms. Although he carelessly pushed her into the bushes in the episode "Bad Little Boy," and called her "kitty" rather condescendingly, she seemed to recover mostly and was seen smiling after Fionna picked her up and spoke in Cake's defense. She tried to break away from Marshall Lee when he kidnapped her and flew to the cemetery, which resulted in a short struggle and caused Marshall Lee to seemingly be pierced through the chest on a spear. When Marshall Lee appeared to be hurt, Cake used her body to shield him from the sun while it rose behind them. She was also visibly relieved when he revealed that he wasn't really dying, even though he had kidnapped her moments before. This completely contrasts with the way Jake the Dog persistently attempted to kill Marceline, despite his being terribly afraid of her, in the episode "Henchman."

Prince Gumball

Marshall Lee's relationship with Prince Gumball seems to be similar to Marceline and Princess Bubblegum's rivalry toward one another. When Fionna and Gumball find Marshall Lee on the roof in "Bad Little Boy," they find Marshall was the one who had stolen Gumball's cream puffs. Marshall proceeds to drink the pink color out of a cream puff, then toss it at Gumball's head. When the puff hits him, Gumball's response is to grimace and begin climbing down from the roof, telling Fionna he is going inside and she can come with him if she would like "more polite company." It is unknown what happened to him after Fionna and Marshall Lee ditched him to go to a party. It is presumable that they have a strong dislike for one another, similar to that of Marceline and Princess Bubblegum.

Though in the graphic novel, they seem to be fine with each other when creating the magical wand stick for Fionna. It also shows in the novel that when Marshall Lee takes his leave, he tells Fionna, "Tell Gumball I said bye," showing that he cares in a way. Due to the relationship between Marceline and Princess Bubblegum improving since season 7, Prince Gumball and Marshall's relationship concurrently improves, as well. However, the episode "Five Short Tables" revealed that Marshall Lee is a regret of Prince Gumball, so their relationship is left ambiguous from the standpoint of the show. It can be assumed by their nature of being Princess Bubblegum and Marceline's male counterparts that they harbor romantic feelings towards one another, at least in Marceline's telling of their stories, however, this collides with Marceline's storytelling of Marshall Lee's overly flirtatious behaviour with Fionna, so, their relationship status is currently unknown.

See Marshall Lee/Quotes


  • Marshall Lee has many similarities to Marceline, meaning the Ice King must know her well. However, in "Bad Little Boy," Marceline told the story.
    • While rapping to Fionna in the song, "Good Little Girl," Marshall Lee says that he's from the Nightosphere. He later says that he is a child of a demon (also like Marceline) and is the vampire king.
    • He appears to float in the exact opposite position that Marceline does.
    • He seems to possess the loneliness trait Marceline has, and hides it like she does.
    • His guitar is made from an axe like Marceline's, but is a six-stringed non-bass guitar with a blade on only one-side. Marceline's axe-bass is a 4-string bass guitar, and is double-sided.
    • It is unknown if he is friends with the Ice Queen, like Marceline being with Simon Petrikov/Ice King during the Mushroom War.
  • Rebecca Sugar said that she wanted Marshall Lee to have a few lines in "Fionna and Cake," but they were cut due to time limitations. She wanted him to be voiced by Dante Basco.[4]
  • An alternate character sheet depicts him with green skin, but it was only used in one scene with special lighting conditions.[5]
    • In "Bad Little Boy," his skin is shown to appear green in the rising sunlight, and so do his teeth.
  • When Marshall Lee does the "Sign of the Horns" at Fionna, he has five fingers instead of the usual four.
  • His hairstyle is different in "Bad Little Boy" from "Fionna and Cake." It appears down rather than up; however, this could be because he was first seen in the rain, which could have caused his hair to get wet and fall down.
    • It could also parallel how Marceline's hairstyle isn't consistent.
  • Unlike Marceline and Princess Bubblegum's relationship, which Marceline is the only person to call her by her first name, Marshall Lee doesn't tend to use Prince Gumball's name. When he wants to address him, he simply calls him a sarcastic "your majesty" or a wad.
  • Like Marceline, he enjoys playing music on multiple stringed instruments. In the opening, Marshall Lee has an ukulele with four knobs on it while in "Bad Little Boy," he has another ukulele with a skull on top.
  • He first appeared in the comics in Issue #23.
