Father

Father is the Kids Next Door's most dangerous and evil enemy of all adults. He is the adopted father of the Delightful Children From Down The Lane who were once the members of Sector Z before a horrible accident made them become his children. He is the brother of Nigel Uno's father, Monty Uno who was once a operative named Numbuh 0 and the uncle of Nigel Uno himself. He is also Grandfather's youngest son who he reawakened by using the Kids Next Door's code module.
