We know that Cayden Boyd plays Max, a boy who creates two superheroes Sharkboy and Lavagirl. Now that "We Can Be Heroes" has arrived on Netflix, we never get a mention on how he is doing now that he is grown up. Maybe he and Marissa got married and had a child with the same purpose Max used to have. Hopefully, Robert Rodriguez and his team can help us solve the mystery on why Max is never shown on "We Can Be Heroes." In the meantime, Cayden Boyd has to return as Max so our questions will be answered.
