Killraven

In a future where Martian invaders have conquered Earth, Jonathan Raven was taken captive and trained as a gladiatorial warrior for his alien overlords. Escaping his brutal conditioning, he became Killraven — a rebel leader fighting to free humanity from Martian oppression.

Born into Marvel's Bronze Age with a debut in Amazing Adventures #18 in 1973, Killraven is one of the era's most distinctive science-fiction rebels — a warrior carved from a darker, more speculative corner of the Marvel Universe. Roy Thomas brought this character to life at a moment when comics were reaching for something grittier and more imaginative, and Killraven's world delivered exactly that. Over a publishing history stretching an impressive fifty years across titles like Amazing Adventures, Killraven, and Astonishing Tales, this is a character with real staying power — one who shares the page with compelling figures like Carmilla Frost, M'Shulla Scott, Old Skull, and even Spider-Man, hinting at the rich, sprawling company Killraven keeps. With a key issue to their name and a legacy that runs from the Bronze Age all the way to 2023, Killraven is a rewarding discovery for any collector who loves Marvel's wilder, road-less-traveled corners.
