Power Rangers Time Force is an American television series and the ninth season of the Power Rangers franchise, based on the Super Sentai series Mirai Sentai Timeranger , running for 40 half-hour episodes from February to November 2001.  It was the last full season to completely air on Fox Kids following the sale of Fox Family Worldwide, which included Fox Family, Fox Kids and Saban Entertainment being purchased by The Walt Disney Company.
Originally, a Time Force film was planned, but ultimately went unproduced in light of the commercial failure of Turbo: A Power Rangers Movie and the purchase of the franchise by Disney. A Power Rangers Time Force video game was released in November 2001 for Sony PlayStation, Game Boy Color, Game Boy Advance, and PC.
In the year 3000, Time Force is a police agency that deals with the crimes of mutants, outcasts of society who have developed super powers. Ransik, one of the most dangerous mutants, is arrested and sentenced to life for his crimes including murder and the plan to travel back in time to take over the world. However, after sentencing, he escapes and manages to go back in time to the year 2001, but seemingly kills Alex, the Red Time Force Ranger, in the process. Alex's fiance Jen, as well as Time Force members Lucas, Katie, and Trip, decide to break protocol and go back in time after Ransik. However, upon arriving in the year 2001, they find that the rest of the Time Force morphers are locked, and cannot be used until someone with Alex's DNA uses the Red Ranger morpher. To that end, they find Alex's ancestor Wes Collins, who unlocks the morphers, and then helps them battle Ransik's army of mutants as the Time Force Power Rangers, though Wes and Jen, upset over Alex's death, don't see eye-to-eye initially.
As Ransik continues his quest for total domination of Earth, archaeologists discover a box that, unknown to them, contains the Quantum Ranger morpher and powers. Both Ransik and the Rangers are well aware of its contents, and make attempts to retrieve it. The box eventually falls into the hand of Eric Myers, a member of the Silver Guardians, the city's police force managed by Wes' father, Mr. Collins and Wes's old rival. Eric activates the power, and becomes the Quantum Ranger. Eric, however, becomes cocky and irresponsible with his power, forcing Wes and the Rangers to try to get it back from him; however, Eric defeated them and he kept his powers. Soon he learns the responsibility of using the Quantum Powers and becomes the leader of the Silver Guardians as the Quantum Ranger.
Eventually, the Rangers begin receiving help from an unseen ally from the future in the form of the Time Shadow Megazord. Soon, this ally arrives in 2001 and reveals himself to be Alex, stating that he is alive because something the Rangers have done in the present has altered the future, and that he has returned to fix it. Alex reveals to Wes what was meant to happen in the original timeline and encourages him to take action to set it right. Wes reluctantly agrees, and relinquishes control of his morpher to Alex so he can take care of his father's business while his father lays ill. Alex then briefly leads the team, but his relationship with the Rangers becomes strained when they realize Alex has changed. Alex eventually realizes that Wes is the true Red Ranger and, having nearly destroyed his relationship with Jen, returns the morpher.
When Ransik makes his final assault on Earth, with a powerful army in large amounts Alex orders the Rangers to return to the future, for fear that if they hesitate, they may not be able to return at all. Wes, however, would have to remain behind. The Rangers refuse, and fight Ransik alongside Wes, who, knowing his friends can't stay, forces them into returning to the year 3000, leaving only himself and Eric to stop Ransik, or die trying. When the Rangers return to the future, they learn that Silver Hills was saved, but Wes died in the process. The Rangers are ordered to have their minds erased of their memories from 2001, and encouraged to resume their lives. Angered, Jen returns Alex's engagement ring, and the Rangers return to 2001 to help Wes and Eric. During the final battle, Ransik accidentally injures his daughter Nadira and, traumatized over nearly killing her, surrenders to the Rangers. Right before the Rangers return Ransik and Nadira to the future, Wes and Jen, having soothed over their initially rocky relationship, profess their love for one another. As the Rangers depart, Wes stays behind with Eric to co-command the Silver Guardians. They later meet the rangers from Power Rangers Wild Force in the two-part episode "Reinforcements from the Future".
