Probably being Cursed Sheriff

So this buddy used to be a super tough sheriff on the wild west land, always being emotionless, weird and never connected with others. The only thing people knew about him is he's really badass at dealing with criminals and make sure they'll get the fairest punishment, I mean, being shot with a big hole through their heads.

However, he's suddenly disappeared without any sign, and when the time he's coming back after several years, he's just being there like this shit looking. Nobody knew what happened to him and why he got a huge change over his body. BUT if I were you, I would just run away from him as soon as possible even in a long distance.
Come on！He's got a huge cannon as his one arm, and another arm is being connected to some kind of demon? You just don't want to walk to him and ask for a cigar, do you?
Oh, you know what, there is one more fun fact about him, so he would snap his fingers to make some fire, and use that to ignite his huge-cannon-arm's gunpowder lead....pretty style, right?
