History
The Stigorax were a native species on Terra Alpha who hunted the Pipe People. When the Humans came to Terra Alpha, they were almost wiped out, apart from one of them named Fifi. Fifi was tamed by Helen A, leader of the Happiness Patrol. Fifi obeyed the commands of Helen A and was sent to hunt people who opposed her. Fifi was killed while trying to hunt down the Doctor. (DW: The Happiness Patrol) Therefore Fifi was the last of her kind.
