The Biggest Weakness Of Every Member Of Snyder's Justice League Explained

Henry Cavill's first outing as Superman, "Man of Steel" tested Clark Kent's limits. He learned to develop and use his powers masterfully, fought against an alien military, and defeated General Zod in the only way he could (a decision that haunted him afterwards). The first film didn't have a lot of time to expand on Superman's weaknesses, so that was left for the sequel. In "Batman V Superman: Dawn of Justice," it's revealed that radioactive fragments of Krypton can weaken, harm, and even kill the Man of Steel; it's basically the only thing that can. After a brawl between the world's finest heroes, they eventually team-up against Lex Luthor, who unleashes a Kryptonian monster known as Doomsday on the city of Metropolis.

As Superman, Batman, and Wonder Woman battle the creature, Clark sacrifices himself by plunging Batman's Kryptonite spear into the monster's heart. Unfortunately, weakened by the poisonous rock, Doomsday still manages Superman. While the end of the film hints at Superman's possible return, it isn't until "Zack Snyder's Justice League" that the Man of Tomorrow is restored to life via a combination of Kryptonian tech, the Flash's Speed Force connection, and Cyborg's Mother Box, and even then it takes a minute for Supes to regain his full memory. It should also be noted that magic can harm Superman as well (Diana's golden lasso actually restrains him for a bit), but so far only Kryptonite has weakened Superman enough to kill him.
