Based on the Geoff Johns/Gary Frank 2008 release Superman: Brainiac, Superman: Unbound finds the horrific force responsible for the destruction of Krypton—Brainiac—descending upon Earth. Brainiac has crossed the universe, collecting cities from interesting planets—Kandor, included—and now the all-knowing, ever-evolving android has his sights fixed on Metropolis.
The popular videogame is now a full-length film! Lex Luthor takes jealousy to new heights when fellow billionaire Bruce Wayne wins the Man of the Year Award. To top Wayne’s accomplishment, Lex begins a campaign for President, and to create the atmosphere for his type of fear-based politics, he recruits the Joker to perfect a Black LEGO Destructor Ray. While wreaking havoc on Gotham, Lex successfully destroys Batman's technology – forcing the Caped Crusader to reluctantly turn to Superman for help.
With Gotham City back under his watchful eye, and accompanied by able sidekick Robin, Batman continues to battle crime—but his resurgence awakens a far worse evil at Arkham Asylum: The Joker. In the meantime, Superman has been dispatched by the President to halt Batman’s unsanctioned reign by whatever means necessary. Between the Joker’s diabolical scheme to drag Batman to the darkest levels of insanity, and the Man of Steel’s seemingly invincible physical presence, the Dark Knight must confront adversaries and allies simultaneously while maintaining the peace in Gotham City.
