The plot revolves around villainous businessman Maxwell Lord and involves cyborgs called OMACs (One-Man Army Corps), who can take over humans and turn them into killing machines. There are epic battle scenes between Superman and Batman, as well as Superman and Wonder Woman. Superman, the morally upstanding Man of Steel battles Batman and has more to worry about than Kryptonite. Wonder Woman, is revered by the other supers for her beauty and ass-kicking abilities. The Martian Manhunter, his power to read minds comes in handy as the villain engages in some nifty mind control. Green Lantern, designed the Hall of Justice. His emerald power ring shoots beams of energy. Batman, the most human of the bunch is mistrustful of others, which leads to quite a few problems for the clan. FLASH, is the most enthusiastic superhero, he is happy just to be included, but his ravenous appetite leads to trouble. Aquaman, is not a fan of humans, he is more interested in helping his fellow heroes than lending a hand to land dwellers.
