Vehicle: Mad Wolf
One of Billy's ancestors was a trained rocket pilot and the first monkey in space. Whether by genetic predisposition or not, Billy's ability as a pilot is truly exceptional, and he's the first monkey to enter the F-ZERO Grand Prix. He was raised in a special lab where he was educated in human literacy and communication skills. The lab concurrently developed an F-ZERO racer suitable for a monkey, and bestowed upon him the honor of piloting it in the Grand Prix.
