I've heard of the term Anti-Hero before. Honestly, until recently I thought they were mini-antagonists. You know the side character the hero meets who we see as a friend only to be revealed to be the one who alerted security, screwed up the timing etc on behalf of the untag. Embarrassing, but I know the real definition now. The best example of an anti-hero I've found is Wade Wilson/Deadpool.
I can't remember the last movie that made me laugh so hard. Oh. My. God. :lol: He's a man with power who kills bad guys, for his own vendetta/vengeance. Others, now that I know what an anti-hero is, include V from "V for Vendetta", and Guy Montag from "Fahrenheit 451".
I learned the definition of Anti-hero, and much more, from this video. Great animation in my opinion. Enjoy.
