Mr. Boss is a fat gangster and he is corrupt, child-hating, corporate executive who acts as the de-facto leader of the KND's standard rogue's gallery. He is very physically large, has a bald head, a mustache, an over sized cigar in his mouth, and a hunched back. In Operation: D.A.D.D.Y., Numbuh 1 describes Mr. Boss as his sector's arch-enemy (probably because Father, the Delightful Children From Down The Lane, Cree Lincoln and Chad Dickson all be considered enemies of the entire organization, rather than just Sector V).
