- "I'm almost thirteen, I'm gonna be working for the teens sooner or later, so I figure why not sooner!"
– Numbuh 12 betraying the Kids Next Door.
Numbuh 12 was one of the operatives at Numbuh 86's slumber party in Operation: S.L.U.M.B.E.R..
Appearances
Her first and only major appearance is in Operation: S.L.U.M.B.E.R. when she attended Numbuh 86's slumber party and had a good time with her fellow operatives. She also became the first person to befriend Numbuh 86 after discovering she had none. When the Teen Ninjas attacked the Moonbase, she betrays the KND and gives the Kids Next Door Code Module to Cree, stating that she was almost thirteen and believed that she would have to start working for the teens sooner or later, thus making her the youngest person to work for the teens. She makes her escape with Cree and The Jets, with a sad Numbuh 86 claiming that she was her "only real friend". Afterwards, her whereabouts are unknown and thus joining the Teen Ninjas.
She also had a cameo in a flashback in Operation: M.A.U.R.I.C.E., appearing as a younger version of herself with pigtails rather than a ponytail.
Trivia
