According to Max, Sharkboy was the son of a successful marine biologist. Since he showed so much love for the sharks at the marine station, his father called him Sharkboy. During a storm, the marine station was destroyed; Sharkboy and his father survived, but they were on different life rafts and floated away in opposite directions. The sharks that he loved so much took him back to their cave and raised him as their own, teaching him the ways of the sharks. Sharkboy eventually grew gills, pointed teeth, and fins, and gets super-senses, becoming a half shark-half human hybrid.Max met Sharkboy while fishing on a dock; Sharkboy looked lost, so Max snuck him home. Sharkboy told Max all sorts of stories about Planet Drool, his planet. One night, a girl with firey hair and molten rock for skin came to collect Sharkboy and take him back to Planet Drool so they could save the planet. She was Lavagirl.Sharkboy and Lavagirl burst into Max's classroom and take him to Planet Drool, as they are in need of his help to save the planet from the Darkness.
