Jimmy Neutron is a Nickelodeon-owned and computer-animated media franchise created by John A. Davis in the 1980s and commenced in 1998 with the pilot Runaway Rocketboy.

The franchise focuses on its titular protagonist (voiced by Debi Derryberry), a young boy with a genius-level intellect.

Producer Albie Hecht reported to the Los Angeles Times that the sequel "would be made on the same budget as the first, but with a new batch of inventions and adventures in Jimmy's town of Retroville.
