|First appearance||"Independence Day"|
G-Gnomes are small, four legged white creatures with black stripes on their heads, and short horns with red eyes. The G-Gnomes possess telepathy, allowing them to communicate with each other. The telepathy also allows them to mentally control people, most notably Guardian, and to teach people, as seen in the case of Superboy.
The G-Gnomes were created by Cadmus and produced in huge numbers. They acted like the surveillance system in the Cadmus facility in Washington, D.C., alerting each other when intruders were spotted. Each staff member at Cadmus kept a G-Gnome on their shoulder at all times. This allowed Mark Desmond to use the G-Gnomes' telepathy to mentally subjugate his staff, preventing them from disagreeing with him, and it also allowed for instant telepathic communication. G-Gnomes were also responsible for implanting images into Superboy's mind to educate him.
