Sector C was stupefied in Operation: C.H.A.D. by Mega Mom & Destructo Dad (Numbuh 274's parents), along with almost all other KND operatives. They were revived after Numbuh 274 defeated his own parents and they promised to revive all stupefied operatives.

In Operation: C.O.U.C.H., Numbuh 4 says that there is an emergency at Sector C to get Numbuhs 1, 2, 3, and 5 out of the treehouse so he could watch TV.

This sector was also in the big 2x4 Technology Fair in Operation: S.C.I.E.N.C.E., where their experiment is having a smoku tart. Their video was about a mom telling her son to do all these jobs, so he escapes by putting a smoky tart in his toaster and he disappears.

Sector C makes a bigger appearance in Operation: C.H.I.N.A., when they provide aid for Sector V when the Chinese Army arrives to stop them. Backup arrives with Numbuh 518 leading the rest of the Chinese Kids Next Door and succeeds in holding the Army off until Numbuh 2 and the 2x4 engineers finish the mechanism to turn the Great Wall of China into a huge waterslide.

  • Like the Russian KND, it is likely that the Chinese KND faced or faces opposition from the Communist Chinese government.
  • The Chinese Kids Next Door might hint that China has more than one sector, as there are too many operatives to be located in one whole sector. This is likely due to China being a large country, similar to how the United States (another large country) has more than one sector (i.e. Sector V, Sector T, Sector N, etc.).
  • Humorously, Numbuh 4 originally thought it was in Arizona.
