Simon Barnaky

General Barnaky was the commanding officer of the Brotherhood of Steel. He was also the leader of the elite Brimstone Squad.

Background
Barnaky was a part of the minority within the Brotherhood that wanted changes to policies, including the sharing of technology and knowledge with outsiders and letting in wastelanders. He believed that the Brotherhood of Steel had much to offer humanity, no matter how primitive humanity was; the Whachutu of Peoria are a prime example of people he believed the Brotherhood could help. However, Barnaky was bigoted towards mutants and believed they deserved nothing but scorn. When the elders started to include mutants into the Brotherhood, Barnaky openly spoke out against it. He questioned the wisdom in such an act, voicing his belief that mutations would taint the Brotherhood and questioned if the old elders were right. He was not alone in this view; the elders themselves didn't believe that mutants were truly equal to pureblood humans, but they felt they could contribute in other ways.

General Barnaky had a wife named Maria. He dedicated his life to her and vowed to cleanse the land of impure mutations and monsters to allow normal humans to thrive.

Barnaky was taken prisoner by Gammorin's Army in St. Louis. This same convoy, with the captured general, was then intercepted by the Calculator's robots and Barnaky was taken to Scott City. There, after extensive torture and experimentation, General Barnaky's brain was extracted and put into a robotic suit. The Calculator's plan was that Barnaky's knowledge about the Brotherhood's internal and external workings could be used to facilitate many of the Calculator's further objectives.

Brain bot form
Barnaky, now as a humanoid brain bot with a semi-lobotomized brain and robotic programming, saw the power of the Calculator as humanity's last chance to bring a new order to the wastes. There was now a possibility to offer humanity a world of order and peace, a world free of war, free of mutants and chaos. The brain bot form of Barnaky ignored the fact that the Calculator was corrupted and sought to exterminate all life. Barnaky knew only that his "pacification protocol" was able to bring death to mutant abominations. He successfully retained a part of his consciousness along with new programming without conflict between them. After that, he had become the Calculator's right-hand. He was a protector and advisor, an enemy and betrayer to his old comrades, whom he believed to be corrupted by a genetic mutation. He tried to use his former position as a leader of the Brotherhood of Steel to serve the Calculator's army by effectively erasing the defensive measures of the Brotherhood.

Faced with Barnaky being listed as missing in action, the rank and position of general/commanding officer of the Brotherhood of Steel were given by the elders to Dekker.

While Barnaky's brainless body was discovered in Scott City, the truth about his alliance with the Calculator was only revealed in Vault 0, where the Warrior encountered brain bot Barnaky guarding the Calculator. Barnaky was very confident in his master's goals, believing the Calculator's way to being the best for the wasteland.

Fate

 * He can come back to his senses after the Warrior reminds him of his wife using his locket or his holotape. In this case, Barnaky will become ashamed of his betrayal, his new form, and the prospect of human extermination. After this, the Warrior may put Barnaky's brain into the Calculator, which will then take on a pro-prime human mentality and begin to restore mankind to its prior glory.
 * He can be killed while fighting the Warrior.
