Justice League Heroes

Based on the long-running comic book series Justice League, it was written by comic book writer Dwayne McDuffie. It uses the Snowblind Studios game engine. Three handheld Justice League Heroes games were released at the same time for the Game Boy Advance, Nintendo DS and PlayStation Portable. The Nintendo DS game shares a similar visual style and gameplay mechanics to the console game and serves as a prequel to its story. The Flash focuses on the Flash, with its events occurring concurrently to the main game.

The game features most of the best known superheroes from the DC Universe, including Superman, Batman, and Wonder Woman among others. Each level consists of two members of the Justice League battling a variety of villains and their henchmen. When the game is being played by a single player, the player can freely switch between playing as either of the two Justice League members at any time. In a two player game, the players can only switch which characters they control by mutual consent. There was another Justice League game in development from Midway Games that was canceled in 2004 but, according to Warner Bros., this game is unrelated to the current project. Upon starting a new game, the player has immediate access to Superman, Batman, Wonder Woman, The Flash, John Stewart (Green Lantern), Martian Manhunter, and Zatanna, but more characters and costumes can be unlocked as the game progresses. These unlockable characters can only be used on levels in which the players can choose which characters to take whereas the costumes can be used at any time. The game has three initial difficulties, Easy, Medium, and Hard, and two unlockable difficulties: Elite and Superhero. In each successive difficulty level, enemies do more damage and have more health.

Superman and Batman foil a S.T.A.R. Labs ambush by robots controlled by Brainiac. After Batman and Superman defeat what they think is Brainiac, they discover that they have been diverted by a duplicate while another has raided the vaults of S.T.A.R. Labs. Meanwhile, Zatanna and Martian Manhunter face off against Queen Bee and her drones, who are being assisted in their gradual conversion of Metropolis by some of Brainiac's robots. After Metropolis has been saved, the League respond to a series of attempted nuclear missile hijackings. Despite the League's efforts, one missile is launched undetected during a worldwide communications blackout caused by Brainiac. The League realizes that the missile has been upgraded; capable of breaking Earth's orbit, it has been fired at Mars in an effort to free the White Martians. Superman and Martian Manhunter travel to Mars to stop them from escaping, but this has been yet another diversion from Brainiac who, anticipating their success, took the opportunity to steal vital equipment from the White Martians. Brainiac has also freed Gorilla Grodd from imprisonment, who intends to take revenge on his jailers and humanity. While Wonder Woman assists Superman in stopping the few White Martian vessels that escaped Mars and Martian Manhunter returns to the Watchtower, the rest of the League work together with Solovar to stop Grodd. Alone on the Watchtower, Martian Manhunter is ambushed by Doomsday, who imprisons him and takes control of the Watchtower while Brainiac steals a Mother Box from the League's vaults. Regrouping in an emergency bunker, the League manage to retake the Watchtower, free Martian Manhunter, and defeat Doomsday before confronting the real Brainiac in Siberia. Seemingly defeated, Brainiac suddenly returns to life as his Mother Box activates. Brainiac is disintegrated by Darkseid, who had been manipulating him and has been released from an interdimensional prison. Confronting the League, Darkseid banishes all of them except Superman to another dimension with his Omega Beams. Darkseid proceeds to transform Earth into a new Apokolips and holds Superman in a kryptonite prison. The rest of the League land in an alternate dimension, but regroup and return to Earth, where they rescue Superman and defeat Darkseid. Darkseid is returned to his prison, restoring Earth to normal.
