Mirai Sentai Timeranger (Future Squadron Timeranger) is the twenty-fourth installment in the Super Sentai series, running from 2000 to 2001.
By the year 3000AD, Time Travel has been discovered and thoroughly developed. To prevent possible abuses of this technology, it is regulated by the Time Police, an intergalactic organisation that also captures dangerous alien criminals and holds them in cryogenic stasis for the length of their sentence.
One such criminal, Don Dorneiro, escapes from the Time Police, hijacks a prison ship full of convicts and flees to the year 2000AD. Captain Ryūya of the Time Police sends four cadets to the past to capture him and his minions, Lira and Gien.
Unfortunately, the cadets have been deceived by Lira (masquerading as their captain) and are almost killed upon reaching the 21st century. With their Timeship destroyed, the cadets are trapped in the past until they can apprehend Don Dorneiro and his gang. To aid their mission, they have access to powerful transformation devices called Chrono Changers. However, the Timeranger Project requires all five Chrono Changers to be activated at the same time.
Enter Tatsuya Asami, an idealistic young man yearning to break free from his oppressive father and future as the heir of the prestigious Asami Group corporation. Happening upon the cadets, he becomes their fifth member and vows to change the future for the better even against the pessimism of the other four Timerangers. Later on, an old university acquaintance of Tatsuya called Naoto Takizawa seizes some of the Timeranger technology for himself and becomes Time Fire, a Rival and Foil to Tatsuya himself.
A major theme in Timeranger is the nature of fate. The characters of the future, being from a period where Time Travel has been extensively researched, are resigned to the fact that the future is entirely predetermined. On the other hand, the characters from the present day are determined to change their own destinies: Tatsuya wishes to break free from the future that has been decided for him since his birth, while Naoto wants to gain power in a world where connections and nepotism mean more than hard work. Eventually, the team discover that the entire story was set in motion by one solitary person whose only wish was to change his own future.
The Members are:
.Tatsuya Asami / Time Red:
The Hero and a Lonely Rich Kid who wants to run away from the Asami name. Got roped into the whole Timeranger thing when he stumbled into the rest of the team while jogging.
.Yuuri / Time Pink:
The Tsundereish Action Girl. The team's effective leader. Has an It's Personal issue with Don Dorneiro.
A snarky member who suffers a incurable disease, The Number 2.
.Domon / Time Yellow:
The Big Guy and sometimes a lady chaser. Used to be an MMA grappler but he was banned from the ring for being late to matches.
.Sion / Time Green:
The Smart Guy and Mr Fix It. An alien from the Doomed Planet Hummard and Last of His Kind. Childish and cute. Has empathetic powers. Changes his hair colour every few episodes.
.Naoto Takizawa / Time Fire:
The New Guy, from the present. A Jerkass Rival to Tatsuya who seizes the power of TimeFire so that he can take control of his own destiny and advance up the professional ladder. Resents Tatsuya because he believes he was given everything on a plate, while Naoto had to work hard to be acknowledged (and never was to the same level as Tatsuya).
The Main Villian is really Captain Ryuya, Tatsuya Asami's Identical descendent (give or take a few dozen 'greats'). A Complete Monster. He was the ultimate mastermind behind everything that occurred in the series — from the initial escape of Don Dolneiro to Gien's Madness. In other words, he was responsible for the crisis that took place in the finale (he had seen two futures — one in which 1/3 of the 21st century is destroyed and one in which the 31st century ceases to exist). To make matters worse, the only reason he was trying to manipulate everything was because he had received a vision that he would die in both futures.
