Miller The Cowboy
Miller has fucked up a lot in his life, but bounty hunting was the one thing he never screwed up. It was easy to kill once you got the hang of it and stopped hesitating. Once you've slain enough demons with a steady hand and clear intent, it becomes a routine.
But often times, one slip up is all it takes. Once such simple fuckup had him lain out, eviscerated and disemboweled, on an average cold desert night. An amalgamation of black magic and green organic life towered over him and with thorns for claws and a howling pit for a mouth. It emptied his organs and fused them with its own essence, hoping to make Miller his little demonic mind-blank evil-doing minion. But Miller didn't spend his whole life killing and running to meet his end like this.
He escaped, but not as the same person he was before. Now a half demon with plants for organs and roses for blood, his teeth grow sharp in the night. His tail slithers in the shadows and numerous black thorns sprout from under his skin from dusk till dawn. He continues to slay monsters, now better at it than ever before.
