Alien Alliance Invasion

The attack on Earth by Annihilus and General Zod of Krypton inspired an alien coalition led by the Dominators known as "the Alliance". The various species of the Alliance launched attacks all across the Earth, securing significant ground. Several of Earth's most powerful superhumans formed the Justice League to oppose them. The Fantastic Four provided experimental technology that allowed the members of the JL and the X-Men to be dispatched all across the globe and repel the invasion.
