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.
Nigel Uno a.k.a. Numbuh 1 is the bald, British leader and head operative of Sector V, keeper of the Book of KND and current Earth representative to the elite Galactic KND. Described as a tactical genius by some and as a paranoid workaholic by others, he has risen to become one of the greatest KND operatives ever. Numbuh 1 takes his position and responsibilities as a KND operative very seriously, often engaging in missions for days at a time without rest.
