For those who don't know, Warden's current design is based on his old one from when Deadlock was still Neon Prime, there he was meant to be a riot cop. His story changed though, and now he's an alchemist vigilante.
He's meant to have a big and imposing cloak, which some characters are already commenting on in voice lines.
Personal Opinion
His character is quite interesting to me due to the whole "trained from birth" thing. Dude has to have massive problems, and I hope those get explored in time.
We are probably going to get McGinnis' girlfriend as a regular sheriff/law enforcer soon, and from what I've gathered based on her voice lines she's going to fulfill the "regular" role quite well
