10 Underpowered Characters Who Defeated Major Heroes

Given Wonder Woman is one of three superheroes considered the main and more powerful in the DC universe - that of Batman, Superman, and Wonder Woman - it's understandable that Harley Quinn's chances against her don't seem all that strong.

Yet Harley changes the game, using her ingenuity, her smarts, and the significant advantage that is knockout gas to take her down and steal her costume. It's admittedly not much in terms of a fight, but given that many of Wonder Woman's long-time enemies have never managed to knock her unconscious, it can definitely be considered a win on Quinn's end.

Hilariously, Quinn likely doesn't even consider what she has done a victory against the Amazonian, as she only knocked Wonder Woman out in order to take her costume and 'help her out' by being Wonder Woman for a day.

While it's not going to win any awards for most exciting fight in comics, Harley Quinn taking down Wonder Woman proves that even people without superpowers have a decent chance against heroes given the right field advantage.
