Justice League: Doom is a 2012 animated superhero film based on the Tower of Babel story arc from the JLA comic. The movie is directed by Lauren Montgomery and written by Dwayne McDuffie.
The film opens with Batman secretly recording the Justice League's fighting techniques and weaknesses. However, his computer is compromised by an unknown hacker who steals the files.
The thief turns out to be Vandal Savage, an immortal villain who plans to use Batman's information to take out the Justice League and conquer the world. He hires a team of supervillains consisting of Mirror Master, Cheetah, Bane, Metallo and Star Sapphire to help him accomplish his plan.
Each member of the team uses Batman's files to exploit their respective weakness and try to defeat the League. For example, Star Sapphire attacks Green Lantern using his vulnerabilities related to his love interest, while Cheetah uses Batman's knowledge of Wonder Woman's compassion against her.
Batman, who feels responsible for the situation, tries to redeem himself by helping the League to overcome Savage's plan. However, the League is divided between trusting Batman again and blaming him for causing their vulnerabilities to be exposed.
In the end, the League is able to overcome the supervillains and Savage with Batman's help. The film ends with the League forgiving Batman and acknowledging that their weaknesses are essential to their humanity and heroism.
