Annoyingly Cute Triplets Who Lived Upon the Hill[]
| Name | First/Only appearance | Appearances | Purpose |
|---|---|---|---|
| Annoyingly Cute Triplets Who Lived Upon the Hill | Operation C.A.K.E.D.-F.I.V.E. | Operation C.A.K.E.D.-F.I.V.E. | To not share their scrumptious cake |
The Annoyingly Cute Triplets Who Lived Upon the Hill (A.C.T.W.L.U.T.H. for short) are female triplets who lived at the Alamode during the 19th century. Their mother hoarded the recipe for the greatest cake ever, who refused to share with others. When the KND attacked the Alamode to get the cake, they set off a defense mechanism, freezing close to 5000 operatives (all of whom had to be decommissioned after being thawed, as they were technically over 13). The ACTWLUTH must be Father's grandparents, as their mother is stated by him to be his Great-Grandmother. They strangely appear similar to the blonde Delightful Child, only taller, with sneering expressions
Black John Licorice and his Licorice Pirates[]
Only appearance: Operation L.I.C.O.R.I.C.E.
Appearing in Op LICORICE, the Licorice Pirates are pirates who, as their name suggests, are made out of black licorice candy due to a curse for tearing down all the licorice trees. They fall apart in the sunlight, but reassemble at night. They are led by Black John Licorice (voiced by Marc Graue), whose name is similar to that of Black Jack chewing gum (the anise flavor of which resembles licorice). They capture Heinrich Von Marzipan from KND Arctic Prison because he ate a candy seed that they needed. The seed in question had to be planted on the island the licorice that they took grew on. They had to water the seed with soda while under the moonlight, causing the seed to grow, which would thereby return the licorice pirates to normal. Stickybeard has been involved with them, once a cabin boy on their ship in his youth. Numbuh Five had to team up with Stickybeard and his Candy Pirates to save Heinrich. Together, they foiled their plans and rescue Heinrich. They parody Captain Barbossa-like character and his cursed pirate crew in Pirates of the Caribbean: Curse of the Black Pearl. Different VAs have voiced the Licorice Pirates: Jeff Bennett, Dee Bradley Baker and Mark Hamill.
Coach Wetterhahn[]
Only appearance: Operation L.E.A.D.E.R. (was mentioned in C.H.A.D.)

Ghost Hamsters[]
Only appearance: Operation G.H.O.S.T.
The Ghost Hamsters are the spirits of the hamsters that power the treehouse after those hamsters die. The most recent hamster to die was Chubbo, a rather fat hamster whom Numbuh 3 loved very much. The Ghost Hamsters tried to take Numbuh 3 with them to Hamster Heaven, and they were going to force her after she refused, but Joaquin and the other living hamsters took down the ethereal rodents with soda.
Great White Asparagus[]
Only appearance: Operation A.F.L.O.A.T.
The Great White Asparagus is a giant asparagus beast living in a sea of asparagus who eats people. It ate Numbuhs 1-4. Before it can eat Numbuh 5, it was killed by Stickybeard and his Candy Pirates who removed Numbuhs 1-4 from its stomach.
Jenkins the Butler[]

Jenkins was the butler for the Delightful Children from Down the Lane in Op. G.R.O.W.-U.P. They tested the Age-Changing Cigar on him when they were bored, turning him into a kid and then into a baby. After the KND broke into the mansion, the DCFDTL ordered Jenkins to do something, but as they had not changed him back, all Jenkins could do was bawl. He's voiced by Dee Bradley Baker.

Lunk[]
Only appearance: Operation F.O.U.N.T.A.I.N.
Lunk is a kid that has been delightfulized by the Delightful Children from Down the Lane. He is not to be confused with the member of the Six-Gum Gang, Lunk.

With the help from her future self, she plans to make the world a better place by turning all boys into girls. 75 years later, she had built a Supergirlifier Cannon to turn anything feminine, even the most macho of things, which includes boys in general. Sally Sanban, Numbuh 3's granddaughter helped Numbuh 4's future self infiltrate Margaret's castle while the Boys Next Door (The next KND generation) kept her army distracted.

Mr. B.[]
Only appearance: Operation C.A.B.L.E.-T.V.
Mr. B. (voice of Dee Bradley Baker) was shown running the Kid-Tacular kids channel, whose schedule is apparently overrun with Rainbow Monkeys. He had the figure of an infant (based on Baby Herman from Who Framed Roger Rabbit), except with a "cigar" in his mouth. He despised the KND because they constantly destroy his broadcast satellites, so he gave the KND their own TV show, just so he could get access to their global satellite web in an attempt to turn everyone into babies using his "cigar", (A debate most mothers have with the show, as he constantly has it in his mouth,) which was actually a device to make adults into babies, to make sure that nobody ever called him "baby" again. He gets hit by his own age-changing cigar, turns into a real baby, and is put into the care of his assistants, who are apparently his parents.
After he ended up being turned into a baby himself, the DCFDTL got hold of the "cigar" and later used it to turn Numbuh One into an adult in Op GROW-UP.
Mustaches[]
Only appearance: Op S.H.A.V.E.
The Mustaches are living mustaches that used to be on everyone's face. But not anymore. So they went onto people's faces and took over their minds, making them obsessed with them, mustaches and making them talk with a southern accent. They are currently on the faces of penguins. The leader is voiced by Daran Norris.
Nerd Zombies[]
Only appearance: Operation U.N.C.O.O.L.
By day, they are nerds, the same kind that collect cards and read books. But if one of their cards goes missing, these nerds become Nerd Zombies and go in search of the card thief.

Retirement Home Secretary[]
Only appearance: Operation H.O.M.E.
Not much is known about the Retirement Home Secretary, other than he assists Nurse Claiborne with her retirement home operation and is usually seen at the entrance. He is voiced by Kurtwood Smith.
Patient C ("Cootie Girl")[]
Only appearance: Op O.U.T.B.R.E.A.K.
Patient C, or "Cootie Girl", was what the KND scientists in the Scientific Seabase had locked up, convinced she had cooties. Cree, however, as a threat, set her free and everyone evacuated the treehouse, and Sector V were assigned to go in and get rid of her, unaware of the reason. She's Numbuh 74.239's sister. Voiced by Grey DeLisle.
Senator Safely[]
Only appearance: Operation S.A.F.E.T.Y.

When the Safety-bots went too far and started attacking adults, Safely joined forces with Numbuhs 2 and 4 to shut down the Safety-bots. He knew someone was going to get hurt. He is voiced by Dee Bradley Baker.
Senior Citizombies[]
Only appearance: Operation Z.E.R.O. Movie
The Senior Citizombies {SC} (half-Senior citizens, half-zombies) are Grandfather's private army, which he creates just by touching a person, when infected, the person becomes old, grown up (in kids' cases) and has green wrinkly skin, crooked teeth and yellow pupiless eyes. It is unknown if Senior Citizombies are as powerful as they used to be. The Toilenator (although he fights cooler), Sector V's hamsters, and Numbuh 90 have demonstrated that they probably are (Numbuhs 2 through 5 seem to have gotten stronger). A Senior Citizombie can turn another person into a Citizombie by touching them, the only two ways to transform a Citizombie back to normal is to decommission Grandfather and remove his memory and powers or to put them into the Age-a-tonic Birthday suits though this method isn't quite perfect, as when Numbuh 1 put his team into the suits, several Senior Citizombified parts of them were not covered by the suits, the reason for this is because Numbuh 2 didn't have the proper tools to perfect them (numbuh 3 and 4 had failed to retrieve them).
