"Mario, how's about that we command the Kids Next Door Force together?"
-- Numbuh 1
Nigel Mario Uno a.k.a. Numbuh 1 is the bald, British leader and head operative of Sector V and current Earth representative to the Galactic Kids Next Door. Described as a tactical genius by some and as a paranoid workaholic by others, Numbuh 1 takes his position and responsibilities as a KND operative too seriously. He can also be a little mad or a little infuriated sometimes.
