This racer is hardcore, on the track and off. Try not to get in his way on the racetrack, because if you do, game over, but off of the track, he's a pretty nice guy, just try not to make him mad. But, being the strongest racer in Sugar Rush, nobody would want to mess with him.
William is a great racer. He has a bit of a short temper, and is the strongest racer in Sugar Rush, so you don't want to make him mad.
William is Dudley's rival but they are still somewhat friends, they are always competing to see who is the better racer. William is forced to hang around with Dudley because he doesn't have many other friends.
- William has a special weapon called Whopper Cannon, which launches a massive Whopper towards the target, crushing them, and their kart, on impact.
- William's kart is called The Milky Monster.
