The United Alliance of Evil 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. Contents [show] HistoryThe UAE consists of these leaders and all their respective foot soldiers and monsters. The Machine Empire supposedly left the UAE during Power Rangers: Zeo during their attack on Earth, but later rejoined. UAE forces first came into play during the attack on Eltar, Zordon's home planet. They captured Zordon, and resigned Alpha 5 and Dimitria to a mysterious fate.Dark Specter planned to absorb Zordon's power, but constantly had to hide him from the searching Phantom Ranger and Space Rangers. After various attempts to destroy them, Specter was destroyed by a weapon the UAE had created to use on Earth. Following Dark Specter's demise, Astronema took control of the organization. The various factions launched their attacks: Rita, Zedd, and Vile attacking Triforia and capturing the Gold Ranger; the Machine Empire attacking the Phantom Ranger's home world and subduing both him and the Blue Senturion; and Divatox attacking Aquitar and overwhelming the Alien Rangers. Astronema personally led the attack on Earth, in the events shown in the episode Countdown to Destruction. However, the UAE was defeated when Andros, the Red Space Ranger, shattered Zordon's containment tank. Zordon's life force washed over the galaxy, destroying the monsters, foot soldiers, and most of the villains. It also turned Rita, Zedd, and Divatox into pure, ordinary humans. Astronema is also restored to her normal form of Karone. The UAE was destroyed for the most part, but some remnants still clung. Among these were the UAE created Psycho Rangers and the last Generals of the Machine Empire, as well as the most powerful zord Serpentera. Also, Thrax, son of Rita and Zedd made an appearance in the Operation Overdrive team-up special called "Once a Ranger". Zedd also makes an appearance in Power Rangers: Super Legends.
