Once a Ranger

Part 1
When Thrax is freed, he recruits Flurious, Moltor, Kamdor, Miratrix, Mig and Benglo to destroy the morphing grid forever and destroy the morphers. Andrew Hartford cannot fix the morphers. They use their enhanced skills to kill the villains, but they're powerless, so the Sentinel Knight recruits Kira Ford, Xander Bly, Adam Park, Bridge Carson and Tori Hanson to replace them untill they get them back.

Part 2

Adam Park fights Thrax. Bridge Carson and Mack Hartford team up to destroy Moltor. Tori Hanson and Rose Ortiz team up to destroy the Lava Lizards. Kira Ford and Ronny Robinson team up to destroy Kamdor and Miratrix. Will fights Flurious and his Chillers.
