Later it was revealed she became the empress of all good magic referred to as the Mystic Mother in Power Rangers Mystic Force.

Disgusted at Rita's performance at attempting to conquer Earth, Zedd came to the Moon himself to get rid of Rita and do the job right himself, but would also be unsuccessful. Rita found her way back to the Moon, and placed Zedd under a love spell. The two got married, and continued to fail at world domination. Zedd was finally turned good, along with Rita, by Zordon's energy wave in Power Rangers in Space. He also received a human form.

A bumbling idiot who couldn't get anything right since he destroyed the Thunderzords and the Rangers' powers, Rito is a constant annoyance to his brother-in-law Zedd, especially by calling him Ed. He brought to Zedd and Rita some Tengas and a Vampirus Monster as a wedding present. Rito was destroyed by Zordon's energy wave in Power Rangers in Space.
Master Vile is one of the universe's great evils. He paid a visit to his daughter Rita, and brought with him a special food which would enhance the Tengas' powers.

Master Vile also gained possession of the Zeo Crystal, which he lost to the Power Rangers when they raided the location the Zords were being kept after Globbor disabled them. Master Vile was destroyed by Zordon's energy wave in Power Rangers in Space.
Putties are the expendable warriors made of clay who are sent down to Earth to wear down the Rangers before a monster fight, as well as for sabotage and special missions. Rita's putties would take many different forms, including pumpkin head putties, ball handed putties, and football player putties. Using a powerful clay she found, she created super putties, which were significantly harder to defeat.
When Lord Zedd arrived, he brought with him the Z Putty Patrol, which were more powerful than any previous putties, and had to be hit in the Z spot to be destroyed.
The Tengas are crow-like humanoid creatures sent down to Earth by Zedd and Rita to battle the Power Rangers. Tengas can fly long distances, and they are very strong and stubborn.

Serpentera was left buried on the moon, unused for years until remnants of the Machine Empire unearthed it. They equipped it with a neo-plutonium reactor, and plotted to use it to destroy Earth. As Serpentera made its way towards Earth, it was destroyed by Cole, the Red Wild Force Ranger, using the Wild Force Rider.
