Power Rangers Time Force

Power Rangers: Time Force is the ninth season of the Power Rangers franchise, based on the Super Sentai series Mirai Sentai Timeranger (Future Squadron Timeranger). Time Force was the last season to be produced totally by the defunct Saban Entertainment group. 

Time Force's plot and structure follows similar themes established by In Space and Lost Galaxy before it, employing what many fans considered to be "darker" and more "mature" themes (such as death, implied racism and morally gray characters). Because of this, it is often compared to the predecessor of the season before it. Time Force is also the first of many Power Rangers seasons to adapt the original plot of its Sentai counterpart almost to the letter, with only minor changes to suit its characters. Like its Sentai counterpart, it was the first season to have two Red Rangers.
