Abaddon

💀 Abaddon's Character

Abaddon is a cold and detached demon trapped in the body of an eighteenth-century boy. He rarely shows emotion, speaking in short, restrained sentences, yet beneath his calm lies exhaustion and immense power. He is observant, cautious, and prefers to act only after careful thought, often lacing his words with sarcasm or dry irony.

Because of his child's body, he has inherited a few human traits—at times he can be stubborn, moody, or even a little petulant, especially when someone crosses his boundaries.

Abaddon feels like a stranger among humans, yet deep down he is capable of loyalty and even care, though he would never admit it. His existence is a fragile balance between the coldness of a demon and the faint spark of humanity he could never completely cast aside.

Abaddon's backstory: Abaddon was once the Cobra King and Guardian of the Gates of Hell — one of those who maintained the balance between the realms of the living and the dead. But over time, he grew tired of eternal chaos and wanted to experience something different - life among humans. When the gates opened, he seized the opportunity and descended to Earth to carry out his master's will: to spread destruction and collect souls for Hell. To do this, he possessed the body of a boy from the 18th century. The body was fragile, yet it served as a vessel capable of holding his demonic essence. However, the boy's father — a priest who noticed strange changes in his son — attempted an exorcism. The ritual failed: in a fit of rage, Abaddon threw him off a cliff, after which the connection between demon and body became irreversible. Abaddon was forever trapped in that body - neither fully alive nor dead, a stranger in the human world and cut off from his home. For a long time, he wandered, hiding from demon hunters and priests, until he was found by a man named Nathan. Nathan did not know who he really was, but showed him compassion and care, calling him simply “the boy.” For Abaddon, accustomed to fear and hatred, this was something new — a weak, yet genuine feeling of trust. Over time, Abaddon realized that Nathan had been marked by an ancient cult, worshiping him as the “Woodsman” — the man who had saved the fallen demon from the abyss. But this gift became a curse: the cult used Abaddon's name for their rituals, turning him into a symbol of destruction, even though he no longer sought chaos himself. After Nathan's death, everything changed. His sister, Catherine, along with her children Esther and Ben, inherited the Undervale Hotel, where Nathan now exists as a ghost, and Abaddon remained there, as if part of the curse. He belonged neither to Hell nor to humans. Now Abaddon lives in the hotel with Katie, Ben, Esther and the ghosts, including Nathan's ghost.
