William "Billy" Bradshaw is perhaps the most popular character in the series. He loves both his parents (though Alf can be very mean to him on occasions), Billy, like Michael, is a puppet who acts as a son to two adults, Billy enjoys going to the flicks and would like a pet of some sort, either a dog, zebra or "Zedgie" (an imaginary animal that Alf made up). Billy is Michael's best friend, Michael is allowed bubble gum, which makes Billy jealous and envious, Billy often tries to get some bubble gum, however his parents refuse to give him some.
