Grimjack, back in the '80's, was my kinda 'anti-hero'. Multiverse, Cynosure, death and life, plus John Ostrander and Tim Truman.
Vigilante, around the same time, he takes down crime.
Nightwing, from the Marvel Comics UK stable - Noir never looked so good. 'In the brooding darkness of the blackest night, the Nightraven stings'.
Captain Britain, original and re-vamp, including Excalibur - KIng Arthur, cool outfits and the crazy stories later on.
The Punisher, comics and the more recent movie, because 'God help the guilty'.
Jonah Hex, the wild west was where heroes began.
Sgt. Rock - an ordinary guy, thrown into the horror of war and always there for Easy Co.
Howard the Duck - light relief, 'trapped in a world he never made' but please do not mention the movie.
Luther Arkwright, because Bryan Talbot is a minor deity.
Judge Dredd - He IS the Law!
BUT, if you look at it all closely, they are nearly all off-shoots of Batman, really...
