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.
In the same episode, they competed alongside other operatives and villians in the Scavenger Hunt for the cake, heading in the absolute lead until the fight for Father's pipe, which caused members of Sector W to mutiny against their leader for his reckless nature and relinquish all their findings to Sector V in gratitude for saving them. This allowed Sector V to win the hunt and for Numbuh 1 to gain entry to the GKND.
- Numbuh 363 "Harvey" the bratty, self absorbed, and extremely competitive leader of the group. He will do anything to win, even if it means putting him and his comrades in danger. Despite this, he seems to take being an operative very seriously, and puts his duties second only to himself. He has an aversion to being touched, and will go insane once he does. Harvey was leader until his decommissioning three months later after Operation: I.N.T.E.R.V.I.E.W.S. because of his bad behavior.
- Numbuh 83 "Sonia" is the sweet, innocent and cautious Soda, Snacks, and Treats Officer. She tends to get nervous under dangerous circumstances, and will usually opt for the safest and most practical way out of danger. She is deathly afraid of the dark, and becomes very violent and dangerous when she is forced to go into a dark place. She is very determined and stands up for herself and for the KND on multiple occations. She is friends with Lee, Tommy, and presumably Paddy.
- Numbuh 84 "Lee" is the calm, quiet, straight boy of the group, and currently the Yo-Yo Specialist. He is easily impressed by anything he finds "cool", and is extremely skilled with his multi-purpose yo-yo. He was best friends with Tommy and Sonia prior to being assigned to Sector W. He is most likely friends with fellow team mate Paddy.
- Numbuh 85 "Paddy" is the younger brother of Numbuh 86 and currently the 2x4 Technology Officer. He was only shown in "Operation: D.A.D.D.Y.", before Operation: I.N.T.E.R.V.I.E.W.S., where he was absent.
Due to the fact that most sectors don't get involved in missions too far away from their base, that would mean that Sector W must be near Sector V.
