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.
In The Past, he is seen in Townsville Park with Grandpa Max and The Scotsman. 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.
- His real name, Nigel Uno, references that he is Numbuh One, since uno means "one" in Spanish.
- He is the only member of Sector V who does not have a sibling.
- He is voiced by Benjamin Diskin, who also voices Numbuh Two.
- Diskin also voiced Venom (Eddie Brock) in The Spectacular Spider-Man TV series.
- Like the other Kids Next Door, he's been "aged up."
- This version of Numbuh One being older means that the events of Operation: I.N.T.E.R.V.I.E.W.S. did not happen, which also means that this version of Nigel did not join the Galactic Kids Next Door.
