Only one KND operative per planet may be chosen to join the ranks of the Galactic KND, a decision which is made through an elaborate and highly secretive process.
During the final season of Codename: Kids Next Door, Numbuh 1 is chosen to be Earth's Galactic KND operative. At the end of Operation: I.N.T.E.R.V.I.E.W.S., he passes his final test and confronts Numbuh 74.239, upon which the existence of the Galactic KND is revealed to him and the viewer. But in the end of the movie, it is seen that Numbuh 1 returns to Earth.
In the GKND prologue trailer, it is revealed that the Galactic KND are very much like their Splinter Cell cover up: a corrupt, adult-hating organization who are delusional, genocidal hypocrites bent on the destroying all life forms over the age of thirteen in the universe and they consider adulthood to be a disease that needs to be destroyed at any cost. It is strongly hinted that Numbuh 74.239 is telling Numbuh 1 (including Monty Uno, Mrs. Uno and possibly Sector V) half-truths and lies to cover up the Galactic KND's evil deeds and true motives.

Sequel or Spin Off
In the new series trailer, it's implied that the Galactic KND are actually much more sinister than previously believed, being willing to actually destroy adults and teenagers and planets that they deem as "infested" with adults and teenagers.
This coincides with their cover - the Splinter Cell - who were believed to want to eradicate the world of all adults and teenagers instead of just the evil ones.
It also expands on their claims in Operation: I.N.T.E.R.V.I.E.W.S. that adulthood is a disease.
It is hinted, the Galactic KND are the main antagonists of the sequel series, because of they plan to rid the universe of all adults and teenagers.
It is also presumed that Numbuh 1 has been either corrupted or manipulated by the Galactic KND to become their pawn or loyal servant.
UPDATE: It is to be noted that on the Rainbow Monkey Website, there is an eye missing on the Rainbow Monkey's face where there were two eyes previously. The left eye now goes missing twice. Whether or not this means anything is uncertain.
