Gigabyte

"Gigabit is the result of Omnitron reshaping what was left of Roach into a perfect and loyal second-in-command. Recreating his flesh into metal and wiring his brain, Omnitron programmed Gigabit to become an "example". Gigabit will stop at nothing to please his master, even as going as far as destroying his former allies to prove his worth."

- Notebook Information Gigabit is the robotic, evil, and corrupted form Roach was transformed into by Omnitron following the events of Carnage within "The War Machine" saga of the Roach Chronicles. He has no resemblance to his original self, and is completely robotic; the only thing remaining is his corrupted brain. Without a soul nor any devotion to his former kind, Gigabit would become Omnitron's second-in-command, as well as the saga's secondary antagonist.

Carnage
After the assumed demise of both Roach and Omnitron, Omnitron's hand soon breaks through the debris of his former weapon production facility a few minutes after the US Military left the site. Getting up, Omnitron reveals he also saved a now heavily weakened and wounded Roach. As Roach questions why he saved him, Omnitron explains that Roach would be "spared" by his ultimate plan, saying that Roach would serve a great use to him before punching Roach unconscious. Omnitron soon contacts the rest of his forces, saying it was time for the "transformation" part of their plan to begin before escaping the site with Roach as his new prisoner.

Offscreen, Roach would be taken to the Robot Army's headquarters at the Stanley R. Mickelsen Safeguard Complex, where the Robot Army created a new robotic body for Roach. Omnitron soon kills Roach, but preserves his brain in the new robotic body. As Roach awakens in his new body, Omnitron continues to work on Roach, rewiring his brain to make him just like Omnitron; a soulless robot bent on destroying humanity. Upon Omnition's completion of his work, Roach was now reborn into Gigabit, devoid of all of his former positive traits and now extremely loyal to Omnitron.
