10 Comic Characters You Won't Believe Joined The Justice League

10. Atomica

When DC Comics launched the New 52, they created a female version of The Atom called Rhonda Pineda, AKA Atomica. When the diminutive super-heroine helped the heroes of Earth stop the Atlanteans from invading the surface, she was sworn into the Justice League.

After the League discovered a mysterious artefact called Pandora's Box that could access other universes, Atomica revealed her true intentions. She isn't a super-heroine at all. She's a complete psychopath who enjoys torturing children. You know what the crazy thing is? That's not the worst part!

Atomica is from a universe where every person is evil. She activated Pandora's Box to allow her team, a twisted version of the Justice League called the Crime Syndicate, to invade the world.

Thankfully, the forces of Earth managed to defeat the Syndicate, and Lex Luthor killed Atomica by crushing her with his foot.

In hindsight, it seems careless that the League allowed Atomica into their inner circle considering they knew nothing about her. However, this wasn't the first time the League welcomed a villain into the group, and it certainly wasn't the last.
