"I am... most unsatisfied."


Father is a paternal figure who is an ultimate figure of authority and the archnemesis of the KND Organization. His ultimate goal is to destroy the Kids Next Door so that evil adults who punish kids for no reason and who don't care about kids can rule the world unopposed. Father's body is completely black with a red outline along his body and eyebrows, giving him a silhouette-like appearance with few other discernible features, the most notable among them being his bright yellow eyes.

Father resides at the Delightful Mansion From Down The Lane with his children, the Delightful Children From Down the Lane, where he plots to destroy the KND. Father usually sends other villains to carry out his work and rarely attacks the KND personally, and is thus much less often seen than the Delightful Children. He was first seen in Operation: G.R.O.W.-U.P., the Season 1 finale and the first 30 minute episode of the series.

It is revealed in Operation: Z.E.R.O. that Father's true identity is Benedict Uno (also called Ben for short), the brother of Monty Uno and thus the uncle of Numbuh 1. The Delightful Children are also explained to be the result of a Delightfulization Chamber that blew a fuse when used on the kidnapped members of Sector Z.
