Old Moonbase
The Moonbase is the most top-secret and important of all KND headquarters. As its name suggests, it is situated on the Moon and was first established when the kids were sent away by the adults (as seen in Operation: A.R.C.H.I.V.E.). All the high-ranking Kids Next Door operatives live here, including Numbuh 86 (who is Head of Decommissioning operatives when they turn thirteen) and Numbuh 362 (who is the Supreme Leader of KND upon the resignation of KND operative Chad, formerly Numbuh 274). As revealed in Operation: K.I.S.S., there's a KND Prison here build specifically for teenagers scheduled for decommissioning. The Moonbase is featured in Operation: E.N.D, Operation: S.L.U.M.B.E.R., and Operation: G.R.A.D.U.A.T.E.S.; it is also briefly seen in F.U.G.I.T.I.V.E. and U.N.D.E.R.C.O.V.E.R, the moonbase is situated on an unknown plant. Shown in Operation: VIDEOGAME, it can transform into the KND TREEHEMOTH. In Operation: Z.E.R.O. Its revealed the entire moon base is the ultimate weapon and can be presumed it must be only used as an absolute last attack (if you look closely you will see the base is shaped like a missile), Sector V crashed it into Grandfather to defeat him once and for all (which failed but is revealed to be a double trap and they manage to Decommission him). According to Grandfather, the old Moonbase weighed about 39 gazillion tons and is made out of metal and duct tape.
New Moonbase
A new, bigger, cooler and more futureistic Moonbase was built with a monument to Numbuh Zero in the middle of it. This version of moonbase was only seen once since Op. Zero. In Operation T.R.I.C.Y.C.L.E., Numbuh 362 ordered Numbuh 20/20 to fire a massive tomato sauce weapon from the moonbase to attack The Tommy's giant monster tricycle, with no effect ("what kind of brain-dead idiot would think ketchup would do anything anyway!"), The New moon base is also shown in Operation T.R.E.A.T.Y. and the invaded version of billy and mandy
