Injustice 2 will pick up where Injustice: Gods Among Us left off, With batman and Superman still squaring off against each other. Both are in need of new allies, as the war of attrition has taken its toll, so developer NetherRealm Studios is adding a new character to the mix.

Enter Brainiac.

"Brainiac possesses superior intelligence, impossibly advanced technology, and inexhaustible resources," Dominic Ciancolo, cinematic director on Injustice 2 for NetherRealm, said in a blog post. "The overwhelming threat he poses to Earth forces Batman to question everything he knows. It also makes him consider crossing lines he’d vowed to never cross."

Ciancolo said that the team wanted to move the story forward without repeating the previous narrative. They had a lot of fun developing the characters in the first game and wanted to do the same in the sequel. The new threat will test both Batman and Superman, even in their adversarial relationship, he said.

Injustice 2 comes out on May 16 for PlayStation 4 and Xbox One.
