Borax is a member of the Varox.
Borax landed on Earth and allied with King Mondo upon learning that he was also out to destroy the Power Rangers, Mondo offering him the Rangers' power if he worked with Mondo to destroy them. Borax attacked when the Rangers tried to find out the Gold Ranger was. Borax shot and greatly weakened Gold Ranger. The Rangers blasted Borax with the Zeo Cannon, which temporarily defeated him. The Rangers tried to tend to the Gold Ranger, but Orbus made Borax grow, forcing the Rangers to send the Gold Ranger to the Power Chamber while they confronted Borax in the Zeo Megazord. Borax went underground and soon knocked down the Zeo Megazord in a surprise attack. He then leapt out from underneath the Megazord, but the Rangers retaliated by striking Borax with their saber, leaving him weakened. Then the Zeo Megazord destroyed Borax.
- Borax is the final monster to be destroyed by the Zeo Megazord on it's own.
