Generator Gawl is a 1998 12-part anime series. The story is set in 2007, when Professor Takuma Nekasa uncovers a gene code that will unlock the human body's greatest mystery and expose mankind to its greatest threat. As a result, Gawl, Koji, and Ryo—three young scientists from a future period—have traveled back in time to undo this mistake. Though the trio intended to arrive one year before the calamity, they are instead transported three months prior to the event. In their effort to save the world, they are opposed by the mysterious and cunning Ryuko Saito, a scientist who prefers the future as it is. Saito is assisted by Generators, unearthly assassins posing as humans. As Ryo and Koji try to complete their mission, Gawl himself must "generate"—becoming like his enemies to fight on their terms.

Twelve years ago, the Earth was attacked by giant invaders. To defend our planet, the Earth's greatest minds and corporations assembled to design a giant robot of incredible power. Unfortunately, as with most government projects, the contract went to the lowest bidder. Fortunately, by the time the robot was ready, the mysterious invaders had already disappeared without a trace. The giant robot became first a curiosity, then a tourist attraction. But now the invaders are back and the only thing in their way is Dai-Guard and a young team of office workers who've been supplementing their regular incomes as part time pilots and tour guides. Can these reluctant heroes halt their alien foes while simultaneously concealing the defects in their giant robot?
