He grew up to become a scientist and technician. Like the other Pluvians, Martinex's body was completely covered by facets that were crystalline in appearance. This design was so that the Pluvians could withstand the extreme temperatures of their world. Martinex could also emit heat and cold from his hands. Martinex became the last surviving Plutonian after the Badoon exterminated all the other Plutonians, as he was working on Pluto's moon Charon. The Pluvians had been forewarned of the attack, but the ship they were escaping on was destroyed by the Badoon. Martinex escaped the Badoon using a telepod and teamed with Vance Astro, a human astronaut from the 20th century with psychic powers, Charlie-27, a Jovian who was the last of his race as well, and Yondu, from Alpha Centauri, to fight the Badoon as the freedom fighters, the Guardians of the Galaxy. It was later revealed Starhawk had manipulated events to bring them together.
