“A soccer player, computer expert, a musician, and a science teacher join forces to become Power Rangers and help save the Earth from mutant dinosauric beings that wish to eradicate all human life and return Earth to the age of the dinosaurs.In this season, Tommy Oliver, of Mighty Morphin Power Rangersto Power Rangers Turbo fame, returns as a paleontology professor in Reefside, California. When he is assigned three detention students, Conner, Ethan, and Kira, they end up finding the Dino Gems, paving the way for them to become the Dino Thunder Power Rangers. Conner gains the power of the Tyrannozord, as well as superspeed; Ethan gains the power of the Tricerazord, as well as the ability to make his skin super-strong; Kira gains the power of the Pterazord, as well as a sonic scream. Tommy (known often as Dr. O) himself joins the team as the Black Dino Thunder Ranger, and they are also later joined byTrent Mercer as the White Dino Thunder Ranger. During the course of the series, the team adds to its arsenal 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 Brachio Zord, the carrier for all the other Zords. At the end of the series, Conner, Kira, Ethan, Tommy, and Trent finished off Mesogog but burned out their Dino Gems in the process.

A year after stopping Mesogog, the three main teens arrive at Reefside High for a reunion. Conner is working on starting a soccer club for kids. Ethan is attending Reefside Tech. Kira has moved to New York City in an attempt to start a recording career. So far; Conner is having trouble raising money for the club, Ethan’s schedule is hectic, though Kira has been spotted on the radio—doing a cat litter jingle.

Kidnapped into the future, they aid the S.P.D. Rangers in defeating Gruumm. They learn that Conner will set up a series of soccer camps for kids, Ethan will eventually develop computer systems and software (and the like) which continue to be used for several years into the future. Some of the software is used by Space Patrol Delta (S.P.D.) and Kira will become a major singing star. After assisting SPD, the trio is sent back to the very moment they were kidnapped without any memories of their involvement. Their Dino gems and morphers remained locked away in an unknown location by SPD.

This was the first time the two teams of Rangers would meet. In a later episode of SPD (“Wormhole”), the SPD Rangers would travel back in time to 2004. Gruumm has returned to defeat the Rangers so he would not face them in the future. Both teams of Rangers teamed up and defeated Gruumm – again. However as with the first team-up only the SPD team remembered it but with the second team up only Gruumm and a few others remember.

Also, in the Operation Overdrive team-up episode Once A Ranger, Kira was one of the five former Power Rangers chosen by the Sentinel Knight to replace the Overdrive Rangers when they lost their powers (the others beingAdam Park as the second Black Power Ranger – though also wielded the Green Zeo Ranger and first Green Turbo Ranger powers, Bridge Carson as the Red B-Squad SPD Ranger – though he was Green in his series, Tori Hansonas the Blue Wind Ranger, and Xander Bly as the Green Mystic Ranger). She and the other “Retro Rangers”, as they have been referred to, dealt with the current villains until the Overdrive Rangers’ powers were restored, and both teams fought one battle alongside each other before the former Rangers went back to their old lives. This is the third time Kira has fought alongside Bridge, however it is unlikely her memory was erased this time, so this would be the first time that she remembers.”
