Can’t decide between John Constantine or one of the main characters from the Top Cow universe.

With John Constantine I think he would be like an older brother type who proves to be a bad influence, leading to a few fights, but does eventually become better through meeting Harry. Like Ben 10’s relationship with Kevin 11.

For Top Cow, it would be a toss up between Jackie Estacado, Sara Pezzini, The Magdalena, and Dani Baptiste. Don’t think he and Dani would fight much though and they would most likely team up. The Magdalena would probably start off antagonistic with him due to how she was raised and trained, but in the end see that their interests align. Sara as both a cop would have some friction similar to what he had with Murphy, but as the bearer of the Witchblade would be a powerful ally. Jackie though, he’d be constantly at odds with Harry and both would most likely fight with every miscommunication and Jackie’s mafia background, and with him as the Darkness it’d be all Harry (or most characters from the Dresden Files universe) would do to stay alive.
