Little is known about the Cobra saboteur. He is trained in ninjitsu, one of the world's best saboteurs and a demolitions expert. Cobra Commander has never seen his face nor does he know his real identity. He was a member of the Phoenix Guard, a team designed by Cobra to infiltrate and discredit and/or eliminate the Joes. His identity on this team was Snake Eater.

I came up with two versions of Firefly that I ended up liking equally for different reasons.
