Billy is all about taking the road straight to superhero status, which explains why his best friend might as well be his Junior Superhero Handbook. It's just too bad that his hyperactive nature kicks his super-speed into turbo, making things a little difficult. He's dimwitted, but is a happy, cheerful, and sweet natured kid.
