Abaddon

Full name: Abaddon of the Gerasenes Birth date: The beginning of time (allegedly) Age :10,000+ (immortal) Gender: Male ♂ Species: Demon Skin color: Champagne pink Hair color: Dark brown Eye color: Dark red, Cobalt blue Despite his advanced age, Abaddon is just as childish as the vessel he inhabits. He is easily distracted, extremely vindictive, and prone to violent mood swings, and takes great delight in the suffering of others. He has no regard for how his actions affect people around him, and willfully ignores any and all rules or restrictions that are placed on him. He is also incredibly narcissistic, believing himself to be superior to humans despite being trapped in a child's body without the majority of his powers. Despite being trapped on Earth for three-hundred years and even being spurned by another demon, Abaddon has unwavering faith that someone from Hell will eventually come to Earth to bring him back home.[3]

Abaddon displays various feral tendencies, likely a result of living in the wild for so long. He has been seen hunting and consuming small animals and built a nest in the elevator after destroying the lobby to assert dominance over his reflection. He is very ignorant of modern technology -- until "Ghost Hunters!", he believed televisions were prisons that held shrunken-down prisoners in them,[8] and in "Rollyfluffs" he was unable to comprehend how to click a computer mouse.[5] Abaddon also displays various child-like behaviors. He has a habit of naming things that he becomes attached to, such as a spider and a blender.

For the majority of Season 1, Abaddon's actions are driven solely by his own desires and self-satisfaction. He is prone to tunnel vision, focusing on a single task or concept to the point of obsession, and will not let up until his immediate desires are met. For example, he only showed interest in fighting the Pillowcase Killer because he had stolen his trilby a decade earlier, and once he had gotten it back, no longer cared about the danger that the killer posed.[2] When Esther kept beating him at Connect Four, he became obsessed with winning the game and stalked Esther around the hotel demanding a rematch.[9]

In "The Acolytes of Abaddon", Abaddon starts to question the validity of his immediate and long-term desires. While ecstatic that his cult intended to free him from his vessel, he immediately went to the Freelings' defense and, at Esther's insistence, went back in time to find a way to stop the ritual. He became obsessed with finding a way to regain his powers and keep the Freelings alive, but the more he went back, the more conflicted he became. After talking with Esther the hundredth time around, he decided to acknowledge his attachment to the Freelings, and felt much better after driving off the cult.[6] Likes: Causing chaos, Bones, Torture, Blenders, Beach music, Being worshipped, Spending time with Esther, Winning, Honking the mail truck horn Dislikes:Being contained,Not getting his way, Mothman ,Being yelled at, People stealing his things, Being questioned or commanded, Rabisu, Wooden wind chimes,His cult

Abaddon of the Gerasenes is one of the protagonists of Haunted Hotel. He is an immortal demon who possessed the son of a priest in colonial America, and was bound to the boy's body during a failed exorcism. He has lived on the site of the Undervale ever since, and in 2024, he was taken in by the Undervale's then-owner Nathan Freeling. Abaddon was allegedly born at the beginning of time, and remembers the birth of the solar system and the formation of the Earth. By his own admission, he was born impaled.

In Hell, he was a gatekeeper in the fifth ring of the sunless city, determining which souls would enter to and which souls would fall into the abyss. Abaddon took great pride in his job, fondly recalling memories of attaching various body parts to different places and removing limbs with his mind. While in Hell, he lived three doors down from the demon Mortoth.

He is allegedly married and considers his mother-in-law his greatest enemy. He also had a rivalry with the Assyrian demon Rabisu, who was allegedly always mean to him.When Abaddon was ten-thousand years old, he was sent to Earth to wreak havoc. He went to the newly-settled Midwich, New York, and possessed a nine year-old boy, as was the trend for demons at the time. However, he didn't know that the boy's father was a priest, and he was quickly found out by the priest and captured.

The townsfolk took Abaddon to the future site of The Undervale and the priest conducted a ritual to destroy Abaddon's essence. He bound Abaddon in chains, and then bound his spirit to his vessel's body to prevent him from escaping. As the priest began the spell to destroy him, Abaddon rushed the priest and took them both over the cliff. The priest was killed when he hit the ground, but Abaddon's vessel survived due to his immortality.

Now bound to the child's body forever, Abaddon decided to stay at the site and wait for someone from Hell to come looking for him. Unknown to Abaddon, a cult would eventually form around him and would search for him to bring about the apocalypse.Over the next two-hundred years, the owners of the Undervale property would discover Abaddon and attempt to contain him through various means -- such as burying him alive, drowning him in the lake, chaining him in the attic, and sending him to a boarding school that focused on "tough love". None of these worked, and Abaddon would return to his old ways every time.[3]

One-hundred years after the ritual, Abaddon began leaving the property at night to cause trouble in Midwich. He would break into peoples' homes and steal their things, and generally cause trouble for the townsfolk.[3]

At some point in the past, he entered a temporary alliance with the deer that lived on the property against the Mothman, though to what end isn't clear.[3]

In 2015, Abaddon encountered the Pillowcase Killer during his yearly return to the property. They got into a fight for unknown reasons and PK stole Abaddon's trilby, and Abaddon would hold a grudge against him for the next decade.[2]After Nathan Freeling moved into the Undervale, he found Abaddon in a ditch on the hotel property. Not initially knowing he was a demon, he decided to take him in and raise him in the hotel.[5][6]

After Nathan's suicide in 2024,[1] he left the hotel to his recently-divorced sister Katherine. Katherine and her children moved into the hotel and discovered its supernatural residents.[4] Katherine's daughter Esther took an interest in the supernatural and bonded with Abaddon over their shared affinity for chaos.In his true form, Abaddon is a large demon with a large, circular torso, a long, thin neck, and inverted goat legs. He has six long arms, five mouths,[3] four horns, and three spaded tails. He has moderate red eyes with diamond-shaped pupils and pointed ears.

Abaddon is currently possessing a nine year-old boy[11] with champagne pink skin, dark-brown hair and cobalt blue eyes. When he is aggravated, his eyes become dark red and his pupils contract into slits. His bangs are swept to the right and he has fringe falling in front of his ears.In his current vessel, Abaddon wears a long-sleeved Payne's gray doublet with a white rounded collar and thick white cuffs. The front of the jacket is accented with a row of small gold buttons and is held together by a dark-brown belt. He wears coffee-brown breeches, white tights, and black-brown latchets with gold buckles. Underneath his doublet, he wears a white tank top.In "Unfinished Business", Abaddon wore a dirty, dark-gray duster trench coat that he stole from someone's grave.

In "How to Train Your Demon", he wore a red vest for his job as the hotel "gatekeeper". While pretending to be Katherine's nephew, he wore a blue and white baseball cap paired with a leather baseball glove to cover up his missing hand.

For the ceremony in "The Acolytes of Abaddon", he wore a crown with large antlers and a blue robe. He wore the quilt Esther made him around his neck.
