– Numbuh One

Numbuh One (real name Nigel Uno) is the undisputed leader of Sector V in the cartoon Codename: Kids Next Door.

Physical Appearance

Nigel usually wears a red turtle-neck sweater, grey shorts, white socks, and brown shoes, which act as rocket shoes for him when he clicks his heels together. He is seldom seen without his sunglasses; most noticeably of all, he is bald.


War Against Fuse

The Future

In the Future, he, along with Dexter, are battling enemies in Tech Square in front of Dexlabs. He is not seen after that.

The Past

Numbuh One

In The Past, he is seen in Townsville Park with Grandpa Max and The Scotsman. His missions mostly have the player stopping fusion monsters from attacking areas like Townsville Mall and Sunny Bridges Auditorium. He is one of the people who suspected Grim to be a traitor, despite having teamed up with him previously on The Grim Adventures of KND crossover.

Other Appearances


His sunglasses are a possible drop from defeating fusion monsters. An item based on the S.M.E.L.L.M.E.T. his Fusion  wears is obtainable by using the E.G.G.E.R. at Sector V in the Future.
