During the Imperium invasion, Hawkgirl was telepathically summoned by J'onn J'onzz to assist in repelling the invaders. Hawkgirl was teamed with Superman to take out the aliens' factories, which propelled smoke into the air to block out the sun. They were unsuccessful and were both captured. J'onn, Wonder Woman, Flash and Green Lantern attempted to rescue the two but were themselves captured. The six heroes were held for the alien invaders leader. After Batman had successfully infiltrated the factory and reversed the smoke process, the group was able to free themselves and destroy the factory and its duplicates around the world. In fact, Hawkgirl was responsible for destroying the Imperium when he attempted to escape on board his personal shuttle craft.
Due to her efforts during the invasion, Hawkgirl was invited aboard the Watchtower, and formed the Justice League along with Batman, Superman, Wonder Woman, The Flash, Green Lantern and J'onn. |
