Billy Stumps is a monster truck driver and one of Kick's daredevil idols.
Famous for being an extreme daredevil, Billy is one of Kick's main influences. He's missing his left arm (which is why he is called "Stumps") but this is due to him being born without it according to the show's creator, Sandro Corsaro. He can appear as a cameo in a poster by Kick's door. He is shown in various cameos from photos and has appeared in person in "Stumped", "Exposed", "Stumped Again", "Rocked" (portraying Gunther) and "Last Fan Standing".
