Earth 2, also known as Universe 2, was a planet in a universe parallel to Earth. Most of the history of this Earth remained the same, though it diverged in the early 21st Century following the Apokolips War when E2's Superman, Wonder Woman and Batman perished. Eventually a new generation of superheroes emerged to fight against the forces of evil. This included a new Batman and Superman, Red Tornado, Dr. Fate, the Flash, Green Lantern, Hawkgirl, Huntress and Power Girl. During the Second Apokolips War, the original Earth 2 was destroyed by the forces of Darkseid.
Eventually, following the Convergence, Telos gave up his planet body to the survivors of the Second Apokolips War. Green Lantern then proceeded to transform it into an almost identical Earth to the last. As new city states began to spring, the heroes continued to protect their people even though new threats also began to arise.
