Codename Kids Next Door is about the secret Kids Next Door Organization, a worldwide group comprising thousands of kids joined in mutual struggle against adult tyranny. They fight villains that embody specific menaces to children overall; such as Knightbrace (going to the dentist), Count Spankulot (spanking), the Common Cold (self-explanatory), Windsor and the Queen Tie (wearing ties), Mrs. Dirt (taking a bath), and Father/Benedict Uno, (the ultimate figure of authority).

Following a period of training, kids are assigned a secret code and sent to a "sector", that is, a treehouse of gigantic proportions. The KND Organization HQ itself is set on the moon (Moonbase). Kids follow their oath of protecting other kids as well as battling adulthood until the age of 13, when they are "decommissioned": their brains are washed-clean of memories of any past KND activity, upon which they are thence considered teenagers, and a threat to KND!
