Numbuh 86's real name is Fanny Fullbright who is the Head of Decommissioning in the KND and is in the same class as Sector V. Numbuh 86's father is none other than the evil Mr. Boss, who claims that his own children are an exception to his hatred of kids. She has two younger brothers, Shaunie Fulbright and Numbuh 85 (Paddy Fulbright). In Operation: E.N.D., it is stated that Numbuh 86 was in the same kindergarten class as Numbuh 1 and possibly some of his teammates (As Numbuh 1 and Numbuh 2 have been best friends since kindergarten, it's highly likely that Numbuh 86 has known Numbuh 2 since then too). In Operation: M.A.U.R.I.C.E., it is revealed that she was in the Health Unit of the Kids Next Door before becoming Head of Decommissioning. During that time period 3 years ago, she did not appear to hate boys back then. She seems to have a close relationship with her boss, Numbuh 362 and with Numbuh 3 (as they both share their love for Rainbow Monkeys).
