Said to be the birthplace of evil; rather than "right" and "wrong", the ruthless nations of Earth 3 cared only for strength above all, the weak deserving only annihilation. This hopelessly corrupted world was thus ruled by the sadistic, unstoppable Crime Syndicate, twisted counterparts to the Justice League.
In Earth 3 performing crimes is as mundane as Prime Earth is fighting crime. And although there are laws and police, these usually only serve their own interests. Like other Earths of the Multiverse, Earth 3 features a gallery of superhumans, but these are selfish and ambitious beings, as anyone in the universe.
The Crime Syndicate fled their universe from a mysterious entity of amazing power, whose abilities they could not predict. Washington, D.C. was laid waste. The Syndicate kept this secret from their allies on Prime Earth, where they claimed publicly that they had killed the population of Earth 3 in response to an uprising. In actuality, the populace was killed by the Anti-Monitor.
