Time travel has often been a factor in the lives of super-heroes. Here are some of the future times encountered by various heroes during their adventures.
The Overseer's world was an alternate future visited by the hero Headlong. In this timeline the alien armor worn by the hero Singluarity had over several years taken over the hero and corrupted him. With his own powers combined with the evolving abilities of the armor, Singularity began an assault against the other heroes of Earth.
With surprise on his side, Singularity was able to eliminate most opposition quickly and set about conquering the Earth. Within a few years he had total control and began to refer to himself as the Overseer. Earth became a dystopian nightmare under the Overseer's iron grip. The only opposition to his rule was a small, disorganized resistance.
It was at this point that Headlong arrived, having been thrown nearly twenty years ahead of his own time due to an accident with his superspeed powers. Coming up against the Overseer's forces, Headlong escaped with the help of the future version of the Tarantula, whose present day incarnation had been Headlong and Singularity's teammate in the original Enforcers of Justice.
With Headlong's help, the future Tarantula and the Resistance were able to strike back against the Overseer. The tyrant was overthrown, though the now liberated world was in bad shape. A means was discovered to send Headlong back to his present, with the hero promising Tarantula he would try to prevent the Overseer from ever coming to be. Back in his own time, Headlong told Singularity what happened to him in this future and convinces him to abandon his alien armor, presumably ending the threat that the Overseer will come to be.
This was not the last that was heard from the Overseer's alternate future, however. The future Tarantula would make the journey back to the present and become the insane Death Spider.
Singularity was killed by a Tarantula from an alternate timeline, seemingly ending the potential threat of the Overseer. However, Singularity was later resurrected as Abyss and apparently some remnant of the alien armor remains within him, meaning that the Overseer may yet one day emerge.
Earth A.D. (After Disaster) is an alternate future where the planet was been devastated by an event simply known as the Great Disaster. The exact nature of the disaster is lost to ancient history; it might have been an asteroid strike, or a global thermonuclear war, or any number of world-shattering natural disasters. Whatever the cause, the Great Disaster caused civilization to collapse and even changed the face of the world as some continents shattered and new ones emerged from the oceans.
In the world that emerged after the Great Disaster, humanity is an endangered species. The mutagen known as Cortexin spread across the globe, causing animals to rapidly evolve in intelligent species. These new beings vie for dominance while humanity scrambles for survival. The Lion-Men control the west coast of North America, separated from the expanding Tiger Empire of the East Coast by the Gorilla Communes of Central North America. Intelligent Killer Whales rule the Pacific Ocean while in Asia the Lion Hordes battle the Mao-Tse-Tigers and the Bear People keep to themselves in their isolated Siberian state. What had been Central Europe is primarily the domain of the Wolves, while Iberia is Baboon territory and Eastern Europe is another Gorilla realm.
The future of Earth A.D. is the original home of the present-day heroes Lupin and Cat. Cat was the crown princess of the Kingdom of Bastia, domain of the Cat-People and located in northwest Africa in what had once been Egypt; while Lupin had been a Wolf-Man from Europe who was in service to the Bastian Royal Family. Cat's team Justice Inc. once briefly visited the alternate future of Earth A.D., after Lupin had come to reveal the amnesiac Cat's true origins.
When he was struck by a blast of chronal energy during a confrontation with the time villain Extant, the hero Galahad was thrown into the timestream. His efforts to return to his own time sent him bouncing like a yo-yo between the past and the future, each jaunt taking him closer to home. The time periods visited by Glahad were:
