If only Bob could go back to being the Mr. Invisible of his superhero days. Back when he wasn't always being compared to his super-talented hardcore basketball god brother and perfect little sister. Back when Roy and Kyle didn't know he existed. To make matters even worse, his dad is really sick and getting sicker.
When Bob begins planning a fundraiser basketball game in support of cancer research, things start to look up. With Roy being temporarily out of the picture after terrorizing some little kids, Bob finally gets a chance to play on the D1 basketball team and ends up helping Roy complete his community service. Maria seems to be becoming more than a friend, and even big brother James starts paying more attention to him, and gives Bob some pointers on how to become The Rocket Man. But cancer rears its ugly head again when a bad fall lands Dad in a wheelchair. Will he be strong enough to make it to the Hoop Heroes 4 Health game?
