Martinex's appearance was redesigned in Guardians of the Galaxy #7 (Dec. 1990). Writer/artist Jim Valentino commented, "No one could draw [Martinex] the same way twice. It was impossible and it was a pain in the butt. What I did was streamline him according to the planes in the body that Andrew Loomis delineated in his seminal book, Figure Drawing for All It's Worth."
