First appearance: Op L.I.Z.Z.I.E.
Elizabeth "Lizzie" Devine, often just referred to as Lizzie, is the overprotective
girlfriend of Nigel Uno, the leader of Sector V of the Kids Next Door organization. Although Numbah 1 would rather avoid the
romantic dates Lizzie seems to prefer, it is clear that he truly does care for her. He was also angered when class president
James "Jimmy" Nixon McGarfield rewired the YesDear 5000 machine, more commonly referred to as the "Boyfriend Helmet", to work
on Lizzie. This helmet was used to brainwash Lizzie into becoming President Jimmy's girlfriend.
Lizzie often calls her boyfriend "Nigie". Her parents or other family members have not yet been
seen or mentioned in an episode.
Lizzie has been involved in the following KND missions: Ops L.I.Z.Z.I.E., Q.U.I.E.T., D.A.T.E.,
C.A.K.E.D.-T.W.O., L.E.A.D.E.R., N.U.G.G.E.T., P.O.O.L., L.U.N.C.H. (she went on that mission alone), S.N.O.W.I.N.G., F.E.R.A.L,
H.O.L.I.D.A.Y, R.E.C.E.S.S., H.A.M.S.T.E.R., and W.H.I.T.E.-H.O.U.S.E. She is rumored to be in Op G.I.R.L.F.R.I.E.N.D.
Twice in the series, the machine most associated with Lizzie was seen, the YesDear 5000, more
commonly referred to as a "boyfriend helmet". In Op L.I.Z.Z.I.E., Lizzie first used the machine on Nigel to make him her obedient
love slave. The second time was in Op S.N.O.W.I.N.G., when the class president James "Jimmy" Nixon McGarfield rewired it to
work on Lizzie to make her his queen because he had a crush on her. Jimmy's assistant, Anna Worthington, was jealous because
she loved Jimmy and helped Sector V rescue Lizzie. Lizzie's disgusting soup made the helmet go haywire, and Lizzie was freed.
She has been a villain in Ops L.I.Z.Z.I.E. She saved Sector V in Op C.A.K.E.D.-T.W.O. Lizzie became friends with Numbah 10
at the end of Operation: H.O.L.I.D.A.Y. after discovering that Numbahs 1 and 10 were cousins rather than dating, as Lizzie
had originally believed.
In Op P.O.O.L., Lizzie had an aggressive and overbearing evil counterpart named Eizzil Enived
(Lizzie Devine spelled backwards). Eizzil has an ex-boyfriend, Negative Numbuh 1.
In Op. D.A.T.E. Lizzie was given the temporary numbuh of 49 when she helped with a mission.
In Op W.H.I.T.E.-H.O.U.S.E., in an alternate universe she was Numbuh 1's wife and the first lady,
and mother of the boy Shirley (she wanted a girl) a.k.a. Viggo or Numbuh 1600.
