How about a whole race of antiheroes?
Great book and movie, I really loved it back in the day.
Another figure from around that time-period is John Constantine. He started out in a smaller role in Swamp Thing, but ended up having his own series in Hellblazer (and a movie that wasn't as bad as I feared it would be, but still ...)
Constantine is always scheming, playing different sides against each other (at one point he sells his soul to different princes of hell so that none of them dares to take him because it would cause problems with the others).
He does occasionally save the world, but you always get the feeling that it's something he does because it's better for him to have it stick around. On the other hand, when he tries to help out old friends, have a relationship and so on, he often causes more harm than good to those he gets involved with.
