Vocatara was an individual who served in the Army of the Galactic Republic as a rocket-jumper sometime before the year 4800 BBY. By then, Vocatara led the Republic as a Supreme Chancellor, at which time the Gank species had begun exterminating other species in a conflict that came to be known as the Gank Massacres. In response to the conflict, Vocatara commissioned the creation of the juggernaut war droids to assist Republic forces and the Jedi Knights with the defeat of the Ganks.
