–Numbuh Two, Operation L.O.C.K.D.O.W.N.
Numbuh Two (real name Hoagie Pennywhistle Gilligan, Jr.) is the technological expert and ace pilot of Sector V from Codename: Kids Next Door, a rotund kid with a blue shirt, brown slacks with suspenders, and a pilot's cap which he never removes. He is the only American-born member of Sector V, living with his mother and his younger brother Tommy. He is known for telling bad jokes in any situation as well as being capable of eating any food he finds in his way.
In both time periods, Numbuh Two is always found within Sector V handing out missions. He was one of the remaining characters who helped the player, while trapped in The Future, to repair the time machine and send him/her back. His Fusion self is equipped with a working KND F.L.A.P.P.U.H. (Flapping Lawnmower Apparatus Propels People Up High), causing him to fly above the ground. He is the first mission handler for players who choose Ben as their guide. He was able to find the Fusion Matter tainted pickles, and helped uncover Fusion Mayor's plot. He sends the player to check on the communication dish that lets him contact the KND Jungle Outpost in Mt. Blackhead. It is soon revealed that Caterplugs had tampered with it, so he has the player defeat the Fusion thieves and retrieve the stolen parts for the dish. Afterward, the player returns the parts to him for maintenance, after which the player is to put the repaired parts into the dish, thus making contact with the KND Jungle Outpost possible again. Numbuh Two is currently in Sector V with Blossom, helping new players adjust to the Fusion conflict and sending them on easy missions.
- His Nano is the only KND Adaptium Nano available. This makes KND the only show featured in FusionFall with Nanos of every type.
- His is the first original Adaptium Nano you get in the game. However, the Rex Nano is the first Adaptium Nano ()
- His Post-Academy Nano mission () is notoriously harder because one of the monsters required for the Nano (Soulo Shells) suffer from strange spawning habits, and is under a time limit of 60 seconds.
- In the tutorial of The Future, Numbuh Two is wearing a frown, but after the fall of Tech Square, he starts sporting a chubby smile.
