10 Times Superheroes Defeated Themselves
3. Batman Fights The Batman Who Laughs - The Batman Who Laughs
Ask any Batman fan who the most important recent addition to the series is, and nine out of ten will say none other than the Batman Who Laughs - an evil version of Batman, made when the Dark Knight was exposed to the mind-changing toxin the Joker releases upon death.
After a series that basically involves Batman getting mutilated by his evil doppelganger every other issue, the finale closes in the Dark Knight getting a well-deserved beat down on his chuckling brethren. Luring the Batman Who Laughs to the graveyard his parents are buried in, Bruce first gets Alfred to shoot the villain as a distraction, then launches several depleted uranium harpoons into him, before electrifying them to finish off the fighting combo.
The fight is finished by Batman picking up the headstone of his beloved mother, and using it to pulverise his opponent, in what is without a doubt the most accidentally hilarious fight to have ever taken place in a Batman comic.
