|Marceline's father, the Lord of Evil|
|Occupation||Lord of Evil|
|Introduced in||"It Came from the Nightosphere"|
|Latest appearance||"All the Little People"(as a toy)|
|Voiced by||Martin Olson|
In "It Came from the Nightosphere," he is freed from the Nightosphere by Finn, who believed that Marceline and her father should be together. Hunson initially shared a shaky parent-to-teen relationship with Marceline that involved an evil rampage throughout Ooo, sucking the souls of many creatures such as the Fuzzy Friends, the Marauders, Hot Dog Princess, numerous ants, most of the penguins in the Ice Kingdom, and some Tree People. He was ultimately defeated by Finn, who released all of the captured souls and sealed the deathless being back into the Nightosphere. Hunson managed to reaffirm his love for Marceline just before leaving. He probably has not been out of the Nightosphere for some time because when he finds out that Marceline turned the family ax into a bass he asks, "Did you turn it into some kind of a lute?"
He appears briefly in "Memory of a Memory," in which he is seen eating his daughter's french fries (which he later says were cold in the episode "It Came From The Nightosphere"). The incident that caused a rift in their relationship and led to Marceline writing her "Fry Song." However, Marceline seems to forgive him, but when Finn kicks him back in the Nightosphere, she says the experience was exhausting.
He reappears in "Daddy's Little Monster," trying to trick Marceline into taking over the Nightosphere.
Hunson Abadeer appeared in the episode "All the Little People" as a tiny C-lister.
He is also the "author" of The Adventure Time Encyclopædia.
Hunson Abadeer is confirmed to be a demon, not a vampire.
He claims to be "completely evil" and is shown to be extremely rational, as well as cold and calculating (these are later shown 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" 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. 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, 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 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.
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 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.
Hunson is Marceline's father. For some time, Marceline loved her father. Marceline 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 Ax 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.
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 "Daddy" 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.
Finn freed Marceline's father from the Nightosphere so that Marceline could have closure with him. The Lord of Evil 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.
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.
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."
- "Memory of a Memory"
- "Return to the Nightosphere" (mentioned and pictured)
- "All the Little People" (as a toy)
- Marceline and her father are voiced by Olivia Olson 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.
- 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. 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. 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.
- His full name was revealed in "Return to the Nightosphere," prior to which he was known exclusively as "Marceline's Dad" or the "Lord of Evil."
- In Spain, his name is "Justo Chupalmas" (Lit: Fair Soulsucker).
- A gender-swapped version of him was mentioned by Marshall Lee in "Bad Little Boy."
- He makes an appearance in the popular webcomic Grim Tales where he is a business partner of HIM, from the Powerpuff Girls.
- 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 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.
