I don't think it matters to much if he's older than the rest because he's not a hero in the same way the rest of them are, doesn't really matter if he's been active before them but I can tinker with it. I thought I did a fair job modernizing the character since I kept major points of his backstory intact and I modernized the character without having to change much. He's a roaming bounty hunter in the comics, and he's a roaming bounty hunter here. The idea of transposing these wild west characters, with all the tropes and themes that come along with the genre, into a modern setting is much more interesting than just simple time travel. If this is what modern-day Hex looks like, what would modern-day Scalphunter or Bat Lash be doing? That's something I want to explore, the ideas and the mythology of the old west violently juxtaposed with our own modern times. As for fitting inside the universe, this a world where we already have vigilantes with superpowers and colorful costumes. A guy with a messed up face doing skip traces doesn't seem that far out of line.
