Androgums were human-like in basic appearance, but with large, orange eyebrows and grey warts around their face. Androgums had heavy builds, and could easily overpower a human. They also had enormous appetites, able to consume massive amounts of food with little discomfort. (TV: The Two Doctors) They were also significantly tougher than a human; Roz Forrester once punched an Androgum on the chin and only broke her fist. (PROSE: Shakedown)
The main trait of the Androgums was their love of food and eating, as they possessed nearly insatiable appetites. Androgum law was that the gratification of pleasure was the sole motive of action. Androgums would eat nearly anything, including vermin and intelligent species (even, it was implied, Androgums).
Androgums were split into clans called Grigs, such as the Quawncing and Franzine Grigs. These Grigs were of great importance to the Androgums, who felt strong loyalty to their bloodlines. (TV: The Two Doctors)
On the Space Station Camera, Androgums were often employed as workers or subjects for experiments. Many Androgums were used in the temporal experiments of Kartz and Reimer. Though all were successful, there was no way of retrieving them, so many Androgums might litter the future and past. Another Androgum, Chessene, had her intelligence artificially augmented by Dastari. Androgums on Camera were killed in the Sontaran attack. (TV: The Two Doctors)
Edwin Bryce wrote a book called Androgum Cookery for Novices: How to Master the Boomerang Spoon. (PROSE: Storm Harvest)
