Hunson Abadeer (a.k.a. the Lord of Evil[2]) is Marceline's father and ruler of the Nightosphere. He is a powerful, deathless demon who is full of chaotic evil. He also enjoys consuming the souls of others, but does not spend much time out of the Nightosphere.

He first appears in "It Came from the Nightosphere" where it is revealed that he has a shaky parent-to-teen relationship with his daughter. However, Hunson manages to reaffirm his love for Marceline just before being sent back into the Nightosphere. In "Memory of a Memory," Finn sees a flashback of him eating his daughter's French fries, an incident that caused a rift in their relationship and led to Marceline writing her "Fry Song." He reappears in "Daddy's Little Monster," trying to trick Marceline into taking over the Nightosphere. He appears again in "Marcy & Hunson," where Peppermint Butler summons him to Ooo to empower a new Night Sword for Finn, and he stays to mend fences with Marceline, helping her fend off an attach by Chicle in the process. 



Hunson, ashamed at what he's done in "Daddy's Little Monster"

He is an embodiment of chaos and claims to be "completely evil" (these are later suggested to be effects of the Nightosphere amulet). He also shows care for things he deems evil; on the animatic, it shows that he is commenting and observing how Gunter is the "most evil thing [he] has encountered" (Reference to Orgalorg) and apparently asking for Gunter's soul before Gunter hits him in the face. Gunter, the Ice King, Jake (because he was in Finn's pocket), and Finn were the only souls that were spared during his rampage through Ooo.

In addition, Hunson Abadeer is shown to be extremely rational, as well as cold and calculating. However, he is not completely emotionless, as he is apparently moved by hearing his daughter's song. He also confirmed that he loves Marceline, and that he was deeply sorry he ate her fries, never meaning to hurt her. This also seems to have changed his personality (shown in the episode "Return to the Nightosphere"), as even with the Nightosphere amulet on, he is far less evil than before, implying that this was a result of the fry argument he and Marceline had. While he is far 'nicer' than before, he may only act so to Marceline, Finn and Jake. Exemplified by the video in "Daddy's Little Monster," before he realized who Jake was, he was quick to act hostile toward him.

He also seems to have a sense of humor in which he shows when he threatens the Marauders in the form of a joke and plays along with their leader's response, calling himself their "Mama." He is also heard singing a song about "sucking up souls and stompin' on ants," though these attributes are not present in Daddy's Little Monster.

"I'm stealing your soul"

He is first shown exiting the Nightosphere as a mass of tentacles, eyeballs, intestines, and various other like appendages, but his usual form consists of a demon-like humanoid with a light blue skin tone, pointy ears, flat dark blue hair, a dark business suit and light yellow eyes with slit neon pink pupils. His face shows slightly more detail than most characters of the show; showing more cheek bone and eye definition than others. The inside of his mouth (aside from his purplish pink tongue) is green, with the hue of green getting slightly darker the closer to the back of the throat. He seems to lack a uvula and a defined chin. His movements are occasionally jerky and unnatural, moving with what appears to be additional or especially stiff but flexible joints. He has the ability to shapeshift, like his daughter, and has been seen with a second, monstrous head with a vertical mouth that usually hides inside his normal mouth at the back of his throat (an effect of the Nightosphere amulet). When he transforms into a large monster this monstrous head emerges from his throat and replaces his normal head. He wears a pair of red boots just like Marceline. However, without the Nightosphere Amulet, he sports a white tank-top, a pair of green-striped pink boxers, and has a slightly bulging belly that is hidden when he is wearing his suit.


Marceline described Hunson Abadeer as "deathless," apparently meaning that he is immortal even going as far to say he literally can't die. He is capable of stealing souls (with the Nightosphere amulet on), shapeshifting, regenerating, and growing to tremendous sizes. He is very strong and flexible so his body can bend many ways making him extremely adept in conflict. An example of this is his ability to swing his leg behind his head, kicking people in the face who try to attack him from behind; he calls it Karate Kick.

In the episode "Daddy's Little Monster," it is revealed that some of Hunson's powers originate from his Nightosphere amulet, which endows its wearer with supernatural powers and also apparently fills them with chaotic evil. The latter seems to happen to Marceline, although she was not prepared for the effects of the amulet, whereas Finn had an idea of what to expect and thus was able to resist its dangerous effects upon alignment.

Marceline and father.


Hunson is Marceline's father. For some time, Marceline loved her father, however, she became upset when he ate her fries, and feels that he doesn't care about her. He would eventually be imprisoned in the Nightosphere and Marceline wouldn't talk to him until the episode "It Came from the Nightosphere".

After coming out of the Nightosphere, she had an argument with him after he took her Axe bass away. Eventually, he realized Marceline's feelings toward him when he listened to the song about their relationship. Toward the end of the episode, they had a talk which fixed the problems between them, but was interrupted when Finn sent him back to the Nightosphere.

Hunson, however, wishes Marceline to take over the Nightosphere in "Return to the Nightosphere" to make him proud. He eventually realizes his fault, and admits that he is proud of Marceline for who she is. In this episode, it also shows that Hunson uses the term "baby" as endearment for Marceline. His relationship with his daughter also seems to have a powerful influence over his personality, as he acts completely evil in his debut due to possible bitterness from their previous argument but after hearing Marceline's song, he acts much nicer afterwards in his later appearances. As an additional result from this, Marceline now visits her father while he is in the Nightosphere.

Hunson is a rather neglectful parent. We can see this from the original lyrics of Marceline's fry song; 'Daddy, why did you leave me, You created me, So don't you wanna see me?' At some point in the past, Hunson was separated from Marceline for a considerable period of time in the aftermath of the Mushroom War, during which she was cared for by Simon Petrikov before he was fully transformed into the Ice King. A young Marceline is seen mouthing the word "Dada" as she cries in the flashback that concludes "I Remember You".  How Marceline was separated from her father and how they were reunited has yet to be revealed in the course of the series. In "Marcy & Hunson," he is shown in a flashback bashing his way into young Marceline's carefully-assembled hut with the family battle axe, noting that someone with glasses (presumably Simon Petrikov) summoned him and that he and Marceline should go suck some souls together. Marceline is clearly shocked and put off by Hunson's obliviousness to her struggle for survival in the post-Mushroom War world. In the present day, Hunson tries spending some time with Marceline while visiting Ooo, but only manages to rile up some obnoxious ghosts at one of her concerts. However, he does help stop an attack by Chicle, and gets Marceline and the others to admit by the end that he's not "all bad."


Finn freed Marceline's father from the Nightosphere so that Marceline could have closure with him. He was under the impression that Finn was Marceline's "evil servant", but upon learning that Finn is "super good", quickly attempted to steal Finn's soul. Hunson then took Marceline's guitar and, using it as a battle ax, stole souls throughout the Land of Ooo. When Marceline's father came to his senses, Finn was able to lock him back in the Nightosphere.

Despite this, in "Daddy's Little Monster," he thinks Finn is cool and doesn't want any hard feelings between them. He shows this when he says, "See how I'm not killing you?" Concerning Finn and Jake, he tells Marceline at the end, "They're all right. And that political rap? Pretty great", showing subtle respect towards the two.


In the episode "Return to the Nightosphere," Jake seems pretty calm around him while he video tapes Hunson.


When he confronts Gunter, Hunson says Gunter was the "most evil thing he had ever encountered." They have an argument and Hunson tries to steal Gunter's soul. However, Gunter slaps him in the face and Marceline's father decides not to steal his soul. Hunson then goes on to shout "Keep your crummy soul!" and they have not interacted since. 

Ice King

When the Ice King looks for the person "who told Gunter he could fly", he unintentionally confronts the Lord of Evil. He scares the Ice King in his monstrous form, causing the Ice King to soil himself, supposedly "by choice," and fly away.

He is depicted as making some sort of deal with Hunson after his transformation into Ice King in issue #16 of the Adventure Time comic, though this is not canon to the animated series.

It is currently unknown if he is aware that Simon Petrikov took care of Marceline after the Mushroom War.

This may be the case as he chose to spare Ice King by scaring him instead of sucking his soul.

Peppermint Butler

Although they have never interacted on screen, it seems that Peppermint Butler had contact with Hunson and may have good relations with him. If you look closely in the episode "Return to the Nightosphere," there is a picture of Abadeer playing golf with Peppermint Butler acting as his caddie. This may further explain Peppermint Butler's dark past as seen in "Death in Bloom."

It is possible that Abadeer and Abraham Lincoln or the similar looking character, King of Mars, once knew each other because there is a picture of them together in Abadeer's house in the episode "Return to the Nightosphere."

  • Marceline and her father are voiced by Olivia and Martin Olson, who are father and daughter in real life. Martin Olson was a staff writer for Penn and Teller, Rocko's Modern Life, Camp Lazlo, and Phineas and Ferb.[3]
  • He wears red boots similar to the ones Marceline wore in "Evicted!".
  • He is the boss in the game Sound Castle 2. Once you defeat him, you get a badge.
  • In "It Came from the Nightosphere", at the moment when he was sucking out Gunther's soul, you can see a little bit of his "monster form" head at the back of his throat. Also in that same episode, when he tries to suck out Finn's soul when Finn screams, "What are you doing?!" you can see his monster form in the back of his throat reply, "Stealing your soul!" You can also see the head when he yawns in "Daddy's Little Monster".
  • According to writer Adam Muto, he is more of a demonic creature than a vampire.[4] It was confirmed that Hunson is a demon, not vampire, by Andy Ristaino.
  • His statue in the Nightosphere jail reads "Hunson Abadeer, our great leader, with us for eternity."
  • According to Jesse Moynihan, Marceline's dad's name is the name his brother gave their car when they were kids. Jesse was also in a band called Hunson Abadeer, but they only wrote one song.[citation needed] Given that he is (in effect) the Lord of Hell, it's worth noting that "Abbadon" has been used by Christian writers as a name of a destroying angel, and by Jewish sources as a region of Hell.
  • In "It Came From The Nightosphere", the eyes of his monster form are green, but in the video shown in "Daddy's Little Monster", the eyes are red.

  • The third-to-last line of the song "Finale: Refusing to Refuse" is "Even if we see Marceline's dad."
  • He has the same eyes as the Demon Cat - yellowish green with slit shaped red pupils.
  • He is the "author" of The Adventure Time Encyclopædia.
  • He professes a strange attraction to Lumpy Space Princess in The Adventure Time Encyclopædia that deeply weirds out commenters Finn, Jake, and Marceline, but this may not be canon to the show.
  • Hunson Abadeer said in The Adventure Time Encyclopædia that if he was to choose a best friend, he would choose Starchie because even if he is not evil, he is a grave digger and if Hunson found he made a mistake, he would easily have him destroyed once he finds someone more compatilble. 
  • In The Adventure Time Encyclopædia, he said that even he doesn't remember his own origins, as he has existed since before time and before everything, when "there were only monsters" like Orgalorg
