Asajj Ventress, a Rattataki.
The Rattataki, were a near-human species characterized by their chalk-white skin and bald heads. Virtually isolated from the rest of the Galaxy, the Rattataki developed a violent society on their home planet of Rattatak, which involved extensive gladiator fights. The most well known Rattataki was Asajj Ventress, a Dark Jedi of the Clone Wars.
