Near the end of this season, Rita and Rito's father Master Vile comes to help conquer Earth. He is very powerful, even more powerful than his children together. He uses his powers to turn back time, turning the Power Rangers into Powerless kids. Zordon calls upon his proteges the Alien Rangers of Aquitar to protect the Earth from Master Vile's monsters and to help work on a machine that would return the child rangers to their proper ages. Unfortunately, only Billy returns to normal as the machine which required the power coins as a power source is stolen by Rito & Goldar allowing Rita & Zedd to destroy the coins. The child rangers then travel throughout time to gather the fragments of the Zeo Crystal to bring time back to normal. During her journey in Africa, Aisha meets Tanya Sloan and realizes that she can do more help to stop the sickness plaguing the wildlife and sends Tanya back with her Zeo Crystal.
