Dino Thunder | 2004

Season Description

Tommy Oliver, part of the teams from Mighty Morphin Power Rangers to Power Rangers: Turbo, is now pursuing a career as a paleontology professor in Reefside, California. Three of his students assigned to detention -- Conner, Ethan, and Kira -- discover the Dino Gems, paving the way for them to become the Dino Rangers. Tommy (known often as Dr. O) joins the team as the Black Dino Ranger with the power of invisibility, and they are also later joined by Trent Mercer as the White Dino Ranger, gifted with camouflage powers. Trent gained his powers from a raw Dino Gem in Mesogog's lab, and the powers were meant for Trent's adopted father Anton Mercer, who is mutating into the creature known as Mesogog. However, Trent saves his father.

The team acquires Zords based on the Pachycephalosaurus, Parasaurolophus, Ankylosaurus, Dimetrodon, and Stegosaurus, the last of which combines with Trent's Zord, a Tupuxuara to form the Dino Stegozord. Tommy pilots the Brachiosaurus Zord, the carrier for all the other Zords. Conner, Kira, Ethan, Tommy, and Trent finish off Mesogog, but the Dino gems are rendered powerless in the battle. A year later, the three main teens reunite. They are pursuing their own, everyday lives – until they are kidnapped into the future to assist the Power Rangers S.P.D.
