After his release from his five year captivity, Proton wandered Johto and Kanto for a year. It was when he was crossing the Nugget bridge above Cerulean city that he was approached by a recruiter. Joining team Rocket seemed to… Appeal to him and he accepted their offer. After a year in the academy, Proton took the rank of Agent, quickly making a name for himself as Team Rocket’s most ruthless and cruel agent. He showed his opponents no mercy and many of them were left with scars from one of his beloved blades, using the skills his father taught him. Quick to pick up on Rocket’s well-outdated security systems, he boldly approached the second-in-command at the time and challenged her that he could improve their systems tenfold.
Well. He did, and was quickly promoted to admin. After the untimely death of the current security officer, Proton was promoted up to executive to head the security and assassination branch of the team… And there’s been nobody better suited for it than the fanged psychopath himself.
Proton is the one that keeps all Rocket HQs secure and safe with the inventions brought in by the Orre branch. While the camera systems are his own wiring genius, he implemented the teleport traps, door locks and password systems into mechanical wonders that even some of Rocket’s own have a hard time understanding. To enter most of the areas, one must have the proper chips to enter, all located on convenient dog tags.
After the events of HGSS, Proton did away with passcodes entirely, and even now he’s trying to come up with a way to replace the tags that don’t involve embedding chips into the backs of team Rocket’s hands. That thought sends shivers down even his spine.
