From Batman to The Punisher, from Lelouche from Code Geass to L from Death Note, from Dumbledore to Snape, from Macbeth to Hamlet, from Shadow The Hedgehog to Kratos from Gears of War, from-okay I'll stop. You probably get it by now. Anti Heroes are very prevalent in most modern entertainment.
What is an Antihero? According to wikipedia it is a hero without traditional heroic qualities (such as idealism, courage, purity, nobility, and integrity). An anti hero is almost always on the side of good, but is always flawed. But that's beside the point.
What Anti Heroic characters from fiction have you idolized, looked up to, or enjoyed the most? In the comments just take the time to list some of the antiheroes you've encountered in fiction.
PS: It's debateble whether or not any of the mane six qualify since they all possess at least one heroic quality (Fluttershy and Pinkie Pie are idealists, Twilight has integrity as does Rainbow Dash who also has courage, Rarity has nobility, etc) An antihero must have none of these qualities, but they must ultimately be a good guy.
Here's a few I'm partial to: Axel from Kingdom Hearts, L from Death Note, Charlie Brown from Peanuts (hey, he's not idealistic), Hobbes from Calvin and Hobbes, and Team Rocket from Pokemon (when they're not the bad guys).
