The heroes of Earth 51.
Earth 51 was one of the Worlds of the Orrery, a universe that was almost always untouched. Once guided by the Monitor Nix Uotan, Earth 51 was practically the perfect universe. That was until a Great Disaster struck it, allowing animals to take the place of humans, who were reduced to savages. In the ruins of Earth 51 lived Kamandi, the last boy. Earth 51 was also notable for being the home of the New Gods from before Flashpoint, some of the last remnants of the Lost Timelines. This was because even though Flashpoint changed much of the Multiverse, Earth 51 was one of the few planets that was barely effected.
