Blue Beetle (Injustice)

Blue Beetle is a supporting character in Injustice 2.

Before Brainiac
Sometime between the fall of Superman's regime and the invasion of Brainiac, the young adult Jaime Reyes became connected to the mysterious Blue Beetle Scarab, giving him immeasurable power in the form of his Blue Beetle super suit. The new hero came into contact with Batman, attempting to clean up, who recruited him as an ally.

Brainiac's Attack
When Brainiac began his invasion of the Earth, Blue Beetle and his fellow new-hero Firestorm were assigned to protect Superman in his red sun prison from Brainiac's forces. However, Brainiac wasn't the problem they had to deal with, instead having to fend off Wonder Woman and Black Adam from freeing Superman to help save the Earth. Though the two heroes managed to fend off the attackers for awhile, they were eventually forced to concede when Batman arrived and agreed to free Superman for the good of the Earth.

Now assigned to fight Brainiac's forces, Firestorm and Blue Beetle were abducted by the alien and used as telekinetic pawns by Gorilla Grodd to find the Rock of Eternity, the magical artifact the heroes planned to use to destroy Brainiac's ship. When Aquaman defeated and killed Gorilla Grodd, Blue Beetle's mind was restored, and he returned to the fight, leading to Brainiac's eventual downfall.
