Biography

Definitely someone from the bygone era of outlaw cowboys, Stetson's past is shrouded in mystery, only ever offering little clues to his previous life. It's known he had a close relationship with his mother, inheriting her revolver, and his father is a sore subject for him. He's not shy to bring up the fact that he's a school dropout, referencing that he struggles to read which suggests he dropped out of school early on in his childhood. There are mentions of a gang he used to run but it's unknown if that was in his hayday or a recent venture. Whatever he was up to in life, it eventually led him to become a loyal servant for Beelzebub.

Whatever had happened during his life, Stetson is immortal despite being purely human. No matter the extent of his bodily harm, or even the complete inhialation of his physical body, he's incapable of ever dying. He's completely hidden from death as both Death and Morana have commented that his soul is hidden in some impenatrable darkness. This doesn't bother Stetson.
This had led him to be bold for his job as one of Beelzebub's Champions. His goofy personality betrays his effeciency and can be downright cold-blooded if the job necessitates it.

His inabbility to die and be taken by other demons has made him the perfect candidate for seeking the Princes and the Aspects. Particularly, the Aspect of Pestilence. The current title bearer is infamous among Champions for being an end of a road. A path that cannot be returned from as Berith, the Aspect, is known to take and experiment on Champions that come his way.
Even with all odds stacked against him to return the Aspect to aid in the retrieval of Asmodeus, Stetson was successful in bringing Berith back. His success being owed to the fact that his undying nature both intrigued and smittened Berith.
