Numbuh 1

Nigel Uno, also known as Numbuh 1, is the main protagonist of the 2002 animated series, Codename: Kids Next Door. He's the bald, British leader, and the former head operative of Sector V and current Earth representative to the Galactic Kids Next Door. Described as a tactical genius by some kids and as a paranoid workaholic by others, Numbuh 1 takes his position and responsibilities as a KND operative too seriously.
Throughout the show, Numbuh 1 speaks with a noted English accent, because his parents come from England and he was born there, but then he moved to the United States when he was 3 years old. According to Numbuh 1, he, and Numbuh 2 have been best friends since Kindergarten. Numbuh 1 had a relationship with Lizzie Devine, who he considered bossy, but deeply cared for until Operation: G.I.R.L.F.R.I.E.N.D. when they broke up.
== Background ==
Numbuh 1 is described as the stern, "workaholic leader of Sector V," as he would rather go on missions than spend his day-off at the beach as seen in Operation: B.E.A.C.H. and Operation: B.U.T.T..
Numbuh 1 is one of the few operatives in the Kids Next Door that takes his missions seriously as seen in Operation: F.E.R.A.L. where he yelled at Numbuh 86 ("... risking my life, endangered my team and spent valuable KND resources, just to get a stupid key chain?!") when he was sent to Rainbow Monkey Island to retrieve a stone tablet with a secret code on it.
Alongside Numbuh 5, Numbuh 1 is considered the only one with common sense on his team. As the leader, he is quick to jump into action and he is quite resourceful, but tends to be paranoid to the point of stretching the truth and using his imagination when analyzing a potential adult threat. He was considered to be a suitable candidate for both Supreme Leader and Global Tactical Officer in the past, but refused both to stay with his friends.
In Operation: Z.E.R.O., it was stated many times by Numbuh 362 (who notes that he puts his team before himself) that Numbuh 1 is reckless, hot-tempered, stubborn, and acts alone. Nevertheless, he's caring and protective towards his friends, putting his full trust into them.
Numbuh 1 is also a huge believer, as he is one of the few KND operatives who believes in the legendary Numbuh 0, who turned out to be his own father, adding further prestige to his already famous reputation.
Although Numbuh 1 is clever, he is also shown to also be rather naive in Operation: D.I.A.P.E.R., as he believes that babies were kidnapped and brought to the hospital to be aged into adults, and that babies come from "baby eggs.
Nigel was among the greatest, if not the greatest of KND operatives, defeating the famed Numbuh 274 in single combat, being revealed as the son of the legendary Numbuh 0 and becoming the single earth representative of the GKND. He, along with the rest of Sector V was looked up to by the majority of the KND, whilst also being considered reckless and impulsive by Global Command.
