Diesel Turner

Diesel Turner was one of the original Rebel Knights in the series. He was originally a school bully at Santo Domingo High School. He is shown/implied to normally be hostile and even violent towards those he dislikes and uncaring for most other people, but this behavior changes as the show progresses. He is often seen carrying around pocket knives and weapons. His best friend was Lyle. Other than him and Lyle working for a moving company in the past summer, much of his familial and personal information from before the events of season 1 is not told or explained. Throughout his time as a Rebel Knight, Diesel became the big brother figure to fellow knight, Cleo Costello, after the death of her older sister, Molly. He formed friendships with newer knights such as Matt Walker, Lori Tran, and twins Cassie and Caitlyn Flores. He would later butt-heads with Jennifer Malone, but they learned to be civil towards on one another due to having similar broken homes. Diesel leaves the knights to join their alien ally Aria in space after his relationship with girlfriend, Natalie Callaway ends due to her having an affair with Grover Jones.

He is played by actor Adam Hicks.

Profile
Diesel had a hard home life, resulting in anger issues and severe claustrophobia. The only person he was close to was his best friend Lyle, whom he had known since age seven. The summer previous the two of them had worked for a moving company together.

Lyle and Diesel were given Saturday detention which was the only reason they had been at the school the day of the alien invasion. Lyle ran out of the school to get away from the attack, but he was fatally injured by the explosions. He managed to return to the school where he told junior Grover Jones that all of the adult were vacated off planet earth and evil child and teenager left behind were on their own before succumbing to his injuries.
