Charlie-27

Born in the pages of Marvel Super-Heroes #18 back in 1969, Charlie-27 is a bona fide Silver Age original — one of Otto Binder's gifts to the Marvel Universe that has proven remarkably durable across more than five decades of storytelling. This future-set warrior has kept extraordinary company over the years, sharing adventures with the likes of Martinex T'Naga, Stakar Ogord, Nikki, and even Captain America himself, and appearing most prominently in Guardians of the Galaxy, Marvel Presents, and The Avengers. With six key issues to his name and a publishing history stretching all the way to 2025, Charlie-27 is no footnote — he's a cornerstone of Marvel's cosmic future, the kind of character whose longevity quietly demands a collector's respect. If you've been sleeping on this one, eighty catalog appearances say it's well past time to catch up.
