Near-Human - bald head
The Rattataki were a Near-Human species characterized by their chalk-white skin and bald heads, similar to the Umbaran race. Virtually isolated from the rest of the galaxy, the Rattataki developed a violent society on their home planet of Rattatak, which involved extensive gladiatorial combat. Dark Jedi Asajj Ventress and warrior Aidus were both Rattataki. Aurra Sing may also have been part Rattataki.
It was said that the Rattataki had the ability to control the minds of other species, forcing a subject to obey the commands of his controller, but that the Rattataki were themselves immune to this power.
For eons, the Rattataki have been constantly battling themselves and their fellow inhabitants. Isolated from the outside galaxy, the Rattataki quickly created new ways to kill each other.
A couple of warlords had gathered an army in the south, but they were killed so they could never be a threat. Only their daughter, Asajj Ventress, escaped.
Rattataki soon learned of life outside their world, when a Jedi Knight, Ky Narec, crash-landed. Though they gained knowledge of the Galactic Republic, they tried to kill him on sight. The Jedi soon found young Ventress, discovering her incredible potential to the Force. Together, they united armies and brought peace to the planet. But some warlords and generals feared them and declared a truce to kill them. They only killed Narec, enraging Ventress. In her rage, she captured and/or killed the ones responsible for her master's death.
