24. Wonder Woman can take on the entire Justice League
At this point, it’s probably quite clear that no one in their right mind would want to mess around with Wonder Woman. She’s often acclaimed as a better fighter than even Superman, who’s himself regularly criticized as being overpowered and undefeatable. Guess no one ever told Diana.
Besides all of the many, many villains she’s defeated over the years, Wonder Woman has bested other superheroes in combat, too. She’s straight-up punched Batman out of a building and into a city street, whereupon she tells him to leave and he does.
After being blinded by snake blood, she still manages to defeat Black Canary, Martian Manhunter, the Flash, and Plastic Man in one go during training. She also deflects a bullet shot by Superman during the same exercise. During another showdown, Power Girl proved to be a formidable opponent (she punched Diana into Canada). However, when Wonder Woman decided to finally bring her full powers to the fight, poor Power Girl didn’t stand a chance.
She’s definitively defeated Superman unassisted at least once, sent Martian Manhunter into a volcano, broken power constructs created by Green Lantern, and disposed of both the Flash and Aquaman with nary a second thought. She also managed to get Batman on multiple different occasions. Sorry, Bruce.
