After rescuing Kara, Barry asks Bruce to help him get his powers back by recreating the original accident. The first two attempts fail, prompting Kara to fly Barry into the storm, where he successfully regains his powers. Kara and Bruce join the two Barrys (Barry and himself in the past) to fight Zod's forces. During the battle with Zod, Kara learns that Zod had intercepted an infant Kal-El's escape pod and killed him during a failed attempt to retrieve the Codex needed to repopulate the Kryptonian species. Zod reveals the Codex is within Kara instead and eventually kills her, obtaining the Codex from her blood. Bruce sacrifices himself in an unsuccessful attempt to stop Zod's invasion.
