Cast Raiden head
Dr. Rex arms
Torpedo Legs
At some point, I may come back and name this guy, but for now he plays a role like what many of the Star Wars Cantina customers played - which is that of filler. Having detailed characters like this for background scenes in a sci-fi verse is invaluable.
So far he has appeared in Joe's Cantina, and to the extent that his role increases in the next season, I might just have to find a name for him.
