Sharkboy is the deuteragonist of The Adventures of Sharkboy and Lavagirl. He is one of Max's best friends and Lavagirl's crush. However concluding the events of the movie, the two of them appear to maintain a relatively platonic relationship- due to the fatal nature of LavaGirl's scalding heat, no doubt. Despite this, she continues to aid him in his efforts to locate his father and enjoys a close bond with him.
