Kranxx's third nega-cousin on his quad-uncle's side, Rench is the hired muscle of the Space
Bikers gang. He may not be the brightest star in the galaxy, but point him in the direction of an obstacle of any size and he'll smash it to pieces with the nearest blunt object he can get his hands on, or with his own fists if there's nothing else around. Detain from a distance!
Rench's uniform is basically, a new version of the Blacktron uniform, and it has the Blacktron logo on it. It is likely that Rench is a member of Blacktron, and if so, he is the first alien to join the organization.
