Edmund Blackadder

Edmund Blackadder is a fictional character from the popular Blackadder series, although he is the titular "hero" of the series he is normally depicted as a very morally dubious anti-hero who became an outright protagonist villain during his "third" incarnation.

The premise of the show is showing different versions of Edmund Blackadder from varied time-periods, most of these incarnations are extremeley selfish, cynical and at times capable of malice - however like many anti-heroes he avoided becoming a complete monster by the fact that he fought against people worse than himself (that is, when villainous characters other than himself appeared of course..).
