Martinex T'Naga

Martinex T'Naga is a genetically engineered descendant of human colonists on Pluto, his body crystallized through deliberate adaptation to that world's extreme environment. A founding member of the original 31st-century Guardians of the Galaxy, he projects heat and cold from his hands and serves as the team's scientific genius.

Born from the cosmic imagination of Otto Binder and debuting in Marvel Super-Heroes #18 in 1969, Martinex T'Naga is a genuine Silver Age Marvel original whose crystalline presence has graced the publisher's pages for over five decades. A charter figure in the far-future mythology that would become Guardians of the Galaxy, he's kept remarkable company across the years — sharing adventures with the likes of Stakar Ogord, Nikki, Vance Astro, and even Captain America himself. With 73 catalogued appearances spanning Marvel Presents, The Avengers, and Guardians of the Galaxy, and six issues flagged as collector-significant keys, Martinex is no footnote — he's a foundational piece of Marvel's cosmic tapestry, the kind of character that rewards the fan willing to dig into the deeper strata of the universe.
