History

  The strange energy life-form known only as the Unimaginable cannot be seen by human eyes, its real shape unknown. Bored with existence, the Unimaginable left its native planet and traveled through space, exploring several other worlds and gathering various life-forms along the way. Arriving on Earth, it saw the JLA in action and decided that it wanted to join the team. However, the Justice Leaguers refused the Unimaginable's demands, and the Unimaginable attacked, first with several of the alien creatures it had gathered, then in the body of one of them, a Doctor Bendorion. The JLA defeated the Unimaginable both times and imprisoned it. Years later, the Unimaginable returned in outer space, battling the Green Lantern named Alia, whom it had previously encountered and wanted revenge on. The Daxamite hero Valor saved Alia and seemingly disintegrated the Unimaginable with a burst of laser vision.
