"Red Ranger, Rescue ready!"

He was seen with his team and Jane Mitchell, Dana and Ryan's little sister.
He is Causisan, with short brown hair. He wore a red shirt with blue tracksuit. He also wore red shoes and orange socks. He also have a special necklace giving by Beatrice. he is seen with a Lightspeed Rescue jacket. At the beach, he wore a red swimming trunk.
Carter is heroic, but sometimes reckless (like in Trial by Fire), always putting himself in danger to save others. He's got a sense of humor (remember anytime with Joel and Ms. Fairweather), but he acts serious most of the time.

- Carter is a firefighter like his Sentai counterpart counterpart. However, of the Lightspeed Rangers, he's the only one that is a fire fighter.
