The United Alliance of Evil (or simply known as the UAE) is an organization of villains led by Dark Specter and later Astronema after Dark Specter's demise. They later launched an assault on the universe but it was stopped after an energy wave, released when Zordon was sacrificed, swept across the universe destroying most of them with a few exceptions. Its members included all of the previous Power Ranger villains along with their henchmen and monsters.
