Abaddon

"Come, come to me, little soul. The Pit is calling you back into its loving, cold embrace, and I will not allow its pining wail go unheeded..."

-Abaddon, arriving in Pride City

Abaddon is an Eldritch Demon who serves as the Gaoler of the Pit, the 9th Ring of Hell. An unfathomably old entity, Abaddon is implied to have existed even before Creation itself, and lives in the perpetual cold darkness of the Pit where he and his Court spend eternity torturing the souls of sinners who betrayed their friends and loved ones in life. Unbeknownst to almost all residents in Hell, he is the only entity who can possibly rival Lucifer in sheer power, and chooses not to only because Lucifer's Sword is lodged in his back, which prevents his full strength from returning. As of currently, he is the Mortal Enemy of Ian Mercer, who escaped his prison, and whom he pursues to the Pride Ring to lock back in the blackness of the Pit.

Appearance
Abaddon is monstrously large demon, standing almost 10 feet tall. He is grotesquely obese, with mangy dark red fur covering his body. His head, which resembles a goat's, is split open, with the skin and fur hanging loosely around his jaw and nose, leaving solid white bone exposed. Seven horns spiral in crazy directions out of his head, and on each one is a solid gold ring-like crown. His Left Eye socket has a second eye jammed into it, the Ocularis Infirnis, which gives Abaddon his ability to see through time and space. It does not fit properly in his head, and bulges out in an unsettling manner, leaking black, inky blood. His arms are extremely muscular, ending in vicious claws. On the right arm is wrapped a length of semi-sentient chain which catch nearby prey.

Abaddon wears no clothes with the exception of a large, dark brown (and bloody) butchers apron. In his back are dozens of swords, arrows and axes, the wounds of which cause flies to buzz around him. Most prominent of these is the Sword of Lucifer, sticking straight out of the center of his upper back.

Personality
"Tell me, insignificant pest...do you feel in control now?"

-Abaddon to Alastor, while displaying his mastery of the Dark

There are many words that describe Abaddon. Pleasant is not one of them. Where as every other demon has some trait or form that makes them appear goofy, Abaddon makes no effort to put on even an attempt of hiding his cruelty or appearing approachable. Dark, cruel, methodical and silent, Abaddon is a beast of few words, but many thoughts. He completely ignores hellhounds, imps and sinners, only starting to notice individuals who are goetia royalty and higher, or his prey when hunting. If spoken to, he may either ignore the speaker wholesale or induce fear in them to make them leave. Despite rarely speaking to "lesser beings", he is not above establishing he is the big fish in the pond with terrifying efficiency. It is implied Abaddon despises all inhabitants of Hell, and constantly plots of ways to torture everyone he meets.

Abaddon is a driven individual when he puts effort into something, and when hunting souls, he is renowned to have never lost his prey. His methodical cruelty, coupled with his fearsome reputation, causes Overlords like Vox and Alastor to cower in his shadow when he passes.

History
"There is a reason your father doesn't come down to MY kingdom, child. Yes, he bested me on the field of combat once...but he fears he cannot replicate that feat..."

-Abaddon to Charlie

Time has little meaning to Abaddon, who by his very nature is ancient beyond age. What is known is that he does not like his current state, and takes his anger out on his prisoners in the Pit.

Around the Fall of Lucifer, Abaddon watched as Lucifer and his angels fought against God, Michael, and the angels of heaven. Using eldritch spells, Abaddon invented terrible weapons, and sold them to both sides of the conflict. After Lucifer was cast out and thrown into the Pit, Abaddon reveled in his position as Gaoler of the Deep, until Lucifer eventually challenged his right to rule. In the titanic duel that followed, Lucifer finally managed to best his foe by thrusting his sword into the back of Abaddon, banishing him to the black reaches of the Pit, while Lucifer was crowned Lord of his new Kingdom, Hell.

Serving as the Gaoler of the souls of traitors and liars, Abaddon torments his charges without end while searching for away to remove Lucifer's sword, as it keeps him from returning to complete strength. Nevertheless, he holds that Lucifer's victory was a fluke, and that he would be unable to pull it off a second time should they meet again. Until then, he bides his time, for if Abaddon was anything other than cruel, he was patient.

Eventually, Abaddon was approached by angels from Heaven on behalf of Hera Mercer, with whom he made a deal. Abaddon would claim the soul of her ex-husband Ian for all eternity, in exchange for the knowledge of channeling beings into human souls to possess them. This would allow Hera and the forces of Heaven to begin grooming Jasmine Mercer as the Horseman of Pestilence. For Abaddon, it was no major concern of his until he considered its implication; the end of the world spelt an opportunity for him to take his revenge on Lucifer, but for that to happen, Ian must be kept out of the picture. Abaddon set about, almost gleefully making Ian Mercer the infamous "Whipping Boy of Hell." After decades of torture, Mercer escaped, vowing to find his daughter and save her from her mother's machinations. And for the first time in eons, Abaddon left the Black of the Pit to find his prey.

Upon arrival in Pride City Abaddon began proactively searching for Mercer, starting with more power beings, and having his slaves post wanted posters all over the city. Due to his Third Eye, Abaddon was able to know that Mercer was on this ring, but due to Lucifer's sword and the sheer amount of souls in the city, his ability was overwhelmed. Still, he could tell if Mercer was close, and began to play a deadly serious game of Cat and Mouse all over the city.

Abaddon would later be contacted by Scoobi Hogger, a demon in Valentino's employ. In return for making Battes utterly subservient to Scoobi with his mind control ability, Abaddon obtained from him the location of Mercer's haven, the Happy Hotel. Abaddon attacked the hotel and very nearly captured Mercer, but was stopped by the combined efforts of all of the staff and residents of the Hotel. Abaddon, enraged at losing his quarry, returned to the Pit for the remainder of the Season to marshal his unholy forces.

Powers and Abilities

 * Superhuman Strength, Durability, Reflexes and Stamina: Abaddon is unnaturally strong, hardy and quick. Though enormously fat, he can move swiftly when needed and with shocking grace. He is also capable of ripping buildings out of the ground, take wounds that would kill any other being, and can exert himself for days before tiring, if he even can tire.
 * Cosmic-level intellect: Abaddon is an Eldritch being, and as a result, is wise, cunning and extremely intelligent. Furthermore, his Third Eye allows him to see all secrets and knowledge, making him a walking library of unspeakable truths.
 * Eldritch Spell-Casting: Abaddon can use forbidden spells to do a variety of tasks, such as tracking prey, torturing prisoners or creating enchanted weapons of war such as Blessing-Tipped Firearms.
 * Mastery of Heat and Cold Powers:Abaddon has total control over heat and cold, and can manipulate fire and ice at will.
 * Nigh-Omniscience: Abaddon's Third Eye allows him to see all whenever he desires, where ever he desires. It is very hard to hide from him because of this.
 * Invulnerability: Most conventional attacks cannot harm Abaddon, and even Lucifer was unable to kill him, only disable him. While he can be harmed by Heaven made Archangel weapons, such things are exceedingly rare in Hell.
 * Regeneration: Even in the event Abaddon is injured, he can regenerate any wound.
 * Darkness Manipulation: The Darkness is owned by Abaddon, and he can use it trap prey, spy on people, and even offensively by using it to attack his prey's shadow.
 * Mind Control and Fear Inducement:Abaddon can easily bend minds to his will, especially by filling them involuntarily with fear. This is also one of this most favorite forms of torture for his slaves.
 * Demonic Transformation: Despite what one might believe, Abaddon can transform into a beast so unspeakable, not even Lucifer is willing to talk about it to this day.
 * Immortality: Abaddon is a being outside of Creation, and as a result, the confines of Life and Death are utterly meaningless to him. As far as he is concerned, he always was, and always will be.

Trivia
