Louis T. Forrest a.k.a Gangrene has one of the most unique histories than most within the terrorist organization Cobra.

He started out as a telesales rep for Arbco Brothers Inc, fresh out of high school innocently enough trying to raise money for medical school.
Successfully climbing the corporate ladder as back stabbing lying salesman, he came to the attention of Tomax and Xamot, and was promoted to a Tele-Viper cadet.

Where he learned of a natural talent he had for electronic and mechanical engineering in addition the lack of remorse when hurting or killing people for his own advancement he quickly rose within the ranks of the Tele-Vipers to an assistant instructor.

On the Day GI Joe and several law offices across the world struck out to destroy Cobra, both Lou and his mentor Bishop hacked into the Cobra files and downgraded their status to "innocent" sales directors.

Having been found innocent of Cobra activity Louis decided to lay low and returned to his first ambition medical school, where he excelled and became a successful surgeon specializing in prosthetics (which he himself designed and constructed). After one too many law suits for malpractice, unnecessary surgery and several suits for insurance fraud Louis found himself taking odd jobs for extreme modification for people with amputation fetishes to pay for lawyers fees. Leaving court one day he saw his old bosses Tomax and Xamot, he followed them into the court room and saw how they defended a clearly guilty man with such grace that the jury was considering allowing a counter suit for damages rendered. He introduced himself to the twins on their way out and was reinstated in the Cobra ranks immediately as a Medi-Viper and with his eclectic skill set floated between Dr. Mindbender, Dr. Scalpel and Overkill assisting each with their work. Which equated to taking bribes from all three to secure test subjects from the wounded Cobra infantry for their various projects).

Earning the code name Gangrene, partly due to the filth darkened green scrubs but mainly due to his actions with a squad of Ice Vipers that had all suffered some minor frostbite, recommending radical amputation and employing his own prosthetic designs to enhance the Ice Vipers abilities, it was decided that Gangrene would have his own lab and area of expertise but would divide his time to Overkill and Mindbender as his work had some merit to the BAT project.

Working with these two very unique individuals through Cobra's return to power and up to the Coil uprising Gangrene, took a hiatus to see who would stand victorious during the Coil/Cobra civil war. Ensuring the protection of Major Bludd Gangrene created a prosthetic hand to replace the one that General Rey cut off in battle. The Major helped defend Gangrene as Cobra Commander's return to power and "restructuring" the Cobra Science and Medical divisions.

As the only human that Overkill will actually speak with let alone allow in his lab Gangrene's position during the BAT uprising is precarious at best. Considering that Overkill maintains that Gangrene should upgrade to a robotic body.

PS this was my first Rit dye job.
