Overview
Power Rangers Dino Thunder is the twelfth season of the television series, Power Rangers.
This incarnation of Power Rangers was adapted from Bakuryū Sentai Abaranger, the 27th entry of Toei Company's long-running Super Sentai franchise. Dino Thunder was also the subtitle of the Korean dub of Abaranger in South Korea and had a similar/identical logo to the American version as well.
The series is notable as it features the return of Jason David Frank as Tommy Oliver as a main character and a dinosaur theme for the powers, abilities and assets from most of the series' protagonists and antagonists. It was the first series to be aired on ABC Family part of ABC.
Plot
A soccer player, a computer expert, a singer and eventually a teacher with a long history of such situations become Power Rangers to help save Earth from the ruthless scheming of the dinosauric Mesogog who wishes to eradicate all human life and return Earth to the age of dinosaurs. Mesogog is assisted in his ways by Elsa, Zeltrax, and an army each of both Tyrannodrones and Triptoids as well as monsters that they call their Mutations.
In this season, Tommy Oliver, from Mighty Morphin Power Rangers to Power Rangers Turbo fame, returns as a paleontology professor in Reefside, California and so he is known as Dr. Tommy Oliver (sometimes called by some in short as Dr. O). When he is assigned three detention students by Principle Randall (the human disguise of Elsa): athlete Conner McKnight, computer expert Ethan James and singer Kira Ford. They end up finding three Dino Gems - one for each teen, paving the way for their destiny as Dino Rangers. Conner gains the powers of both the Tyrannozord and super running speed, Ethan gains the powers of both the Tricerazord and energy-formed skin-shield defense and Kira gains the powers of both the Pterazord and sonic screams.
Five episodes into the series, Tommy once again becomes a Power Ranger by bonding with the Black Dino Gem and receives its power of invisibility as the Black Dino Ranger.
