As a child, Carter was saved from a burning building by a mystery firefighter. This encounter led him to follow in his savior's footsteps and become a firefighter himself. He later found this mystery firefighter to be none other than Captain Mitchell, who recruited him into Lightspeed Rescue. Carter was the first to accept his role and took up the position of team leader as the Red Lightspeed Ranger, and courageously led the Rangers against Diabolico's forces.
