Wilbur Nesbit Newcomb II is the rather prissy and educated cousin of Alfalfa Switzer. Despite his appearance, he's a very capable fighter when he has to be. He turns the gang's All-4-One Club into a benevolent society, later knocking down Butch and The Woim to keep it that way. He's possibly Aunt Penelope's son, but this is unconfirmed.
Cousin Wilbur was played by Scott Beckett.
