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. In Operation: E.N.D., it is stated that Numbuh 86 was in the same Kindergarten class as Numbuh 1. 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 this time period, she may have not hated boys.
Numbah 86 speaks with a thick irish accent and has a loud voice, especially when yelling, which she does often. She is rude, ill-tempered and mean, but is strongly loyal to the Kids Next Door. After her decommissioning she becomes more likable. She cries (along with everyone else) when beloved male operative Maurice is decommissioned.
