Numbuh Eleventy Billion is a fictional persona of Codename: Kids Next Door creator Mr. Warburton, much like Nogoodnik. He is seen as a background character in Operation: Z.E.R.O. along with Numbuh D20 and Mo Willems.
The nonexistent number of "Eleventy Billion" itself is also a running gag in the series, and presumably an in-joke of Warburton.
Trivia[]

- When going by his in-universe persona of "Numbuh Eleventy Billion", Mr. Warburton also refers himself as the supreme leader of the KND.
