Hunson Abadeer

Hunson Abadeer (a.k.a. the Lord of Evil), is Marceline's dad and the ruler of the Nightosphere.

In "It Came from the Nightosphere," he is freed from the Nightosphere by Finn, who believed that Marceline and her father should be together. Abadeer initially shared a shaky parent-to-teen relationship with Marceline that involved an evil rampage through 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 is ultimately defeated by Finn, who released all of the captured souls (Including Lumpy Space Princess who assumed she was "crashing" a "party" after seeing Hot Dog Princess getting "sucked in (there)") and sealed the deathless being back into the Nightosphere.Abadeer 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 axe into a guitar he asks, "Did you turn it into some kind of a lute?" (A lute is a precursor to the guitar, dating back to the Middle Ages.)

He appears briefly in "Memory of a Memory," in which he is seen eating his daughter's 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."

He reappears in "Daddy's Little Monster," trying to trick Marceline into taking over the Nightosphere.

Personality
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 minionship before Gunter hits him in the face. Gunter, the Ice King, Jake (because he was in Finn's shirt pocket), and Finn were the only souls that were spared during his rampage. 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. 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 also is heard singing a song about "Sucking up souls" and "Steppin' on ants."

Appearance
He is first shown exiting the Nightosphere as a mass of tentacles, eyeballs, intestines, and various other like appendages but seems to prefer a big, blue-skinned humanoid with pointed ears, fangs, demonic eyes, and a dark business suit for his form while in Ooo. 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 (most likely part of his true form). Though when he transforms into a large monster this monster 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 shirt, a pair of green-striped pink boxers, and has a slightly bulging belly that is hidden when he is wearing his suit.

Abilities
Abadeer is "deathless," apparently meaning that he is immortal. He is capable of stealing souls, shapeshifting, regenerating, and growing to tremendous sizes. He is very strong and flexible so his body can bend many ways making him extremely good at fighting. 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 Hunson's powers originate from his Nightosphere Amulet, which fills its wearers with chaotic evil.

Marceline
Hunson is Marceline's father, though it is not explicitly stated whether he is her biological father or the being who turned her into a vampire. 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, he had an argument with her after taking 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. But 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.

Finn
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. The Lord of Evil then took Marceline's guitar and, using it as a battle axe, 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 he thinks Finn is cool and doesn't want any hard feelings between them.

Gunter
When he confronted Gunter, Marceline's father said Gunter was the most evil thing he had ever encountered. They had an argument and Marceline's father tried to steal Gunter's soul. However, Gunter slapped him in the face and Marceline's father decided not to suck Gunter's soul.

Ice King
When the Ice King was looking for who told Gunter he could fly, he confronted the Lord of Evil. He scared the Ice King with his monstrous form, causing the Ice King to soil himself and fly away.
