Androgum

Androgums were a barbaric, primitive humanoid race that were used for menial labour in the Third Zone.

Biology
Androgums were Human-like in basic appearance, but with dark hair, large orange eyebrows and grey warts around their face. Androgums had a heavy build, being able to easily overpower a Human. They also had enormous appetites, being able to consume massive amounts of food with little discomfort. (DW: The Two Doctors)

Culture
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 is the sole motive of action. Androgums would eat nearly anything, including vermin and intelligent species.

Androgums were split into Grigs such as the Quawncing and Franzine Grigs. These Grigs were of great importance to the Androgums, leading to a strong loyalty to their bloodline. (DW: The Two Doctors)

History
On the Space Station Chimera, 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 killed. Another Androgum, Chessene, was artificially augmented in intelligence by Dastari. (DW: The Two Doctors)
