First Episode: “Shift into Turbo, Part 1″
Sentai: Gekisou Sentai Carranger
“After the defeat of Maligore, the older Turbo Rangers graduate from high school and resume their normal lives, but are attacked once again by a vengeful Divatox and her forces and an endless supply of detonators and monsters that threaten the citizens of Angel Grove.A new twist into the story involves Zordon and Alpha 5 returning to Zordon’s home planet of Eltar, thereby relinquishing the mentorship of the Rangers to the spectral Dimitria of Inquiris (who is suggested to be Divatox’s long-lost twin sister) and the street-talking Alpha 6.
The Rangers are then joined by Blue Senturion, an intergalactic police robot who brings with him the “Millennium Message”, a pivotal story arc which foretells the later events of Power Rangers: In Space. The four older Turbo Rangers are then retired from duty, “Passing the Torch” to four new Rangers – T.J., Carlos, Ashley, and Cassie, while Justin remains as the Blue Turbo Ranger.
The mysterious Phantom Ranger, whose identity is never revealed and whose powers originate from Eltar, arrives on Earth in the nick of time. Divatox’s brother General Havoc arrives, bringing with him a new Space Base for his sister and a Metallasaurus Zord which steals the Turbo Megazord. The Phantom, who becomes Cassie’s love interest, gives the Turbo Rangers new Rescuezords, and the Rangers later manage to retrieve the Turbo Zords as well.
However, the end of the series brings tragedy and devastation as the Rescue Megazord is self-destructed on T.J.’s command in a failed attempt to destroy Goldgoyle, the Turbo Megazord is in turn destroyed by him and the Turbo Ram is rocketed into Goldgoyle’s mouth, finally destroying him. Dimitria and Blue Senturion leave for the planet Eltar, which has fallen to evil forces (which later turn out to be Dark Specter and the United Alliance of Evil). Alone, the Rangers then find their Power Chamber under attack by Divatox’s forces and are unable to prevent their base from being utterly destroyed, right before Divatox is summoned by a messenger from Dark Specter (who has captured Zordon) to leave the Earth for the Cimmerian Planet. The Rangers are left with no choice but to follow in hot pursuit in a NASADA space shuttle, sans Justin, who chooses to remain on Earth with his father. This leads directly into the sixth Power Rangers season, Power Rangers: In Space.”
