Master Vile

Master Vile, the father of Rita Repulsa and Rito Revolto, arrived on the moon shortly after the Pink Ranger fiasco. Vile disapproved of Rita's marriage to Lord Zedd, wondering why his daughter didn't at least marry someone with a skull. When Vile revealed he had come to the moon in search of the legendary Zeo Crystal, Zedd mocked him, since the Zeo Crystal, kept hidden in the Caves of Deception underneath the Palace, was protected by a forcefield who would destroy anyone who possessed even an ounce of evil. Vile knew of this, of course, and created the Blue Globbor. Vile planned for Globbor to drain Ninjor of his powers, then use those powers to kidnap the Rangers, who he would then force to fetch the Zeo Crystal for him. Tommy, however, managed to steal the Zeo Crystal while the others battled Globbor on Earth. Unfortunately, Vile captured all of the Zords as well as the Crystal, and teleported them to his homeplanet in the M51 Galaxy.

Invading the Youth Center, Vile threw a End Of The World Party, and he began remotely using the Zeo Crystal's power to destroy Angel Grove. The Rangers teleported to their Zords and managed to break Vile's link to the Crystal, returning to Earth to battle Globbor. Vile soon grew to giant size to assist his creation, but was assaulted by the finishing attacks of both the Shogun and Ninja MegaFalconZords. Amazingly, he survived, and retreated back to the moon. He considered his failure to be nothing but a minor setback, and declared that he was here to stay.

Vile later sent his old ally Dischordia to battle the Rangers, and she nearly succeeded in taking control of the Rangers' minds. Vile was foiled once again, however, as Dischordia met her end courtesy of the Shogun UltraZord.

Vile then summoned the Orb of Doom to the Earth, which he used to revert the Rangers to powerless children. When Zedd, Rita, Goldar, and Rito grew and began to attack Angel Grove, he shrunk them back to normal size, revealing that he had more plans for the Earth. Summoning an army of monsters to the Palace, he then sent the best of the lot to Earth, led by his field general, Professor Longnose. When the invasion was defeated by the Aquitian Rangers, Vile threw a tantrum and fled back to the M51 Galaxy, where he said evil always wins.

When the Machine Empire arrived on the moon, Rita called Vile and begged him to let them stay with him. Reluctantly, Vile agreed, despite the fact that Rita would be bringing "that husband of hers."

Master Vile was last seen on the Cimmerian Planet, attending Dark Specter's conference.
