Geryon

Geryon was an archdevil in the Nine Hells, before being ousted from his position as ruler of Stygia. Later, Geryon returned, and sought to reclaim his layer from Levistus.

Description
Although Geryon typically stood tall, his serpentine body stretched to  in terms of length and ended in a venom-dripping barb. His humanoid torso was muscular, with massive, bat-like wings protruding from his back, and his large, bestial arms ended in clawed hands similar to paws. Despite his mismatched bodily structure, the Wild Beast had a kind of raw, animalistic presence that made him weirdly alluring and his head boasted a strangely handsome visage.

Sometimes he took the form of smaller beings to make movement easier, preferring the shapes of monsters like ogres and minotaurs or beasts like tigers.

Personality
Geryon was a brooding being who enjoyed coiling up amongst his treasures and, like a dragon, kept them in a massive hoard. He was also incessant and jealous, persistently pursuing his objectives whether they were his quarry or his former authority. While other devils commanded their fiendish armies from a distance, Geryon was vicious and bloodthirsty, preferring to crush enemies with his own two hands. Although useful in the Stygian wastelands, his bestial savagery was also a weakness that negatively impacted his ability to garner souls and forge proper hierarchies. Despite his barbaric nature and his "Lord of the Filth" title, a mocking play on words similar to Baalzebul's "Lord of the Lies" epithet, Geryon was ironically immaculate and preferred a clean environment, leading some to believe he was slightly insane.

Powers
Even when diminished in strength, Geryon was a terrifying combatant able to rip mortals apart with only his favored weapon, his claws. He used them not only to rip his enemies to shreds, but to restrain them before injecting them with the vitality-stealing venom present in his stinger, a favorite tactic of his. The former lord of Stygia was immune to the cold and naturally regenerated from most injuries at a frightening rate, but his recovery would be temporarily halted if he was hit with blessed weapons, holy power or radiant energy. His gaze could strike terror in his enemies and he was delighted by the sight of his enemies cowering before him, whether a natural response or not.

Despite his brutish appearance and typical demeanor, Geryon was still capable of acting tactically, rivaling Zariel in his reputation for martial skill. Weakening foes from afar before closing in for the kill was one of his preferred methods of fighting and he had a wide range of spell-like abilities allowing him to bewitch his foes, take on other forms, manipulate the cold, create a symbol of pain, pronounce an unholy word, teleport and even grant the wishes of others. He was known to summon gelugons but could also call upon barbazus, hamatulas, osyluths and pit fiends. He would begrudgingly use weapons if necessary, although he had a tendency to lose his composure and descend into an animalistic frenzy when seriously injured, crushing his foes beneath his fists rather than using any kind of plan.

Realm
Geryon made his home in the fortress of Coldsteel, and commanded a number of ice devils, as well as minotaurs he had stolen from Baphomet.
