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.
Weird, I got an old timey constable vibe from him, which I always thought worked well with the current theme. I would prefer it to stay rather than change, honestly. The paranormal angle is cool and all, but it's nice to have some more "regular" folks among the cast for contrast.
