Planet Hulk (2010)

A heroic version of Lex Luthor from an alternate universe appears to recruit the Justice League to help save his Earth from the Crime Syndicate, an evil version of the League. What ensues is the ultimate battle of good versus evil in a war that threatens both planets and, through a devious plan launched by Batman's counterpart Owlman, puts the balance of all existence in peril.

Lex Luthor enacts his plan to rid the world of Superman, once and for all. Succeeding with solar radiation poisoning, the Man of Steel is slowly dying. With what little times remains, the Last Son of Krypton must confront the revealing of his secret identity to Lois Lane and face Luthor in a final battle.

When LexCorp accidentally unleashes a murderous creature, Superman meets his greatest challenge as a champion. Based on the "The Death of Superman" storyline that appeared in DC Comics' publications in the 1990s.

Until now, the Justice League has been a loose association of superpowered individuals. But when they are swept away to Warworld, a place of unending brutal gladiatorial combat, Batman, Superman, Wonder Woman and the others must somehow unite to form an unbeatable resistance able to lead an entire planet to freedom.

In an alternate universe, very different versions of DC's Trinity fight against the government after they are framed for an embassy bombing.

Superman agrees to sacrifice his powers to start a relationship with Lois Lane, unaware that three Kryptonian criminals he inadvertently released are conquering Earth.

An endless army of shadow demons bent on the destruction of all reality swarms over our world and all parallel Earths! The only thing opposing them is the mightiest team of metahumans ever assembled. But not even the combined power of Superman, Batman, Wonder Woman, Green Lantern and all their fellow superheroes can slow down the onslaught of this invincible horde. What mysterious force is driving them? And how do the long-buried secrets of the Monitor and Supergirl threaten to crush our last defense?

Now fully revealed as the ultimate threat to existence, the Anti-Monitor wages an unrelenting attack on the surviving Earths that struggle for survival in a pocket universe. One by one, these worlds and all their inhabitants are vaporized! On the planets that remain, even time itself is shattered, and heroes from the past join the Justice League and their rag-tag allies against the epitome of evil. But as they make their last stand, will the sacrifice of the superheroes be enough to save us all?

In the wake of The Death of Supermen, the world is still mourning the loss of the Man of Steel following his fatal battle with the monster Doomsday. However, no sooner as his body been laid to rest than do four new bearers of the Superman shield come forward to take on the mantle. The Last Son of Krypton, Superboy, Steel, and the Cyborg Superman all attempt to fill the vacuum left by the world's greatest champion. Meanwhile, Superman's death has also signaled to the universe that Earth is vulnerable. Can these new Supermen and the rest of the heroes prove them wrong?

Superman and Supergirl take on the cybernetic being known as Brainiac, who boasts that he possesses "the knowledge and strength of 10,000 worlds."
