Toccomatta was the high inquisitor of Gammorin's Army, as well as Gammorin's second-in-command. He specialized in torture and had a ninety-nine percent success rate at getting prisoners to confess whatever they knew.
Toccomatta was the last survivor of a robot ambush. He took General Barnaky prisoner in St. Louis, and was carrying him to Gammorin when they were attacked. He alone knew that the General was taken alive. By the time a Midwestern Brotherhood squad reached Osceolla, he was dying. With his last breath he revealed another piece of information that was crucial to the plot.
