I have always been curious of this and it retains to comic characters. Anyone know?
@JediXMan: @Glitch_Spawn: Like what Dexter Morgan does?
Yes. He's a killer who goes outside the law. He is a villain if he did that to innocent people. He's an anti-hero if he does it to other killers - or both, as the case may be. It depends on intent, as well.
@JediXMan: @WillPayton: @Glitch_Spawn: I see. It makes a lot of sense.
Other good examples would be Punisher, or Light Yagami from Death Note.
Basically to be an antihero, a character has to be a protagonist who doesnt have the typical "heroic" qualities like idealism, self-sacrifice, etc. He/she's someone who has all kinds of problems and character flaws, but is still charismatic, confident, intelligent, and most importantly... is the one who drives the story forward with their actions.
