Sector W is the youngest KND Sector in the organization around the time Sector V was active. It is first seen in Operation: D.A.D.D.Y., when Numbuh 83 and Numbuh 84 team up with Numbuh 1 to save their team mate Numbuh 85's brother from getting a terrible hair cut. Supreme Leader Numbuh 362 has noted that Sector W had the highest mission success rate in the entire KND in Operation: I.N.T.E.R.V.I.E.W.S., opting to pull Sector V off the Delightful Children's cake mission and send Sector W on the case instead.
