Sauron

Sauron is a pterodactyl-like mutant villain who transforms from human Karl Lykos — a man who absorbs life energy from others. When he drains mutant energy, he becomes the savage, winged Sauron, a dangerous foe of the X-Men.

A creature of the Bronze Age, Sauron swooped into comics via Superaventuras Marvel #25 in 1984, brought to life by the legendary creative pairing of Chris Claremont and John Byrne under the Brazilian imprint Editora Abril. Across a publishing span that stretched nearly three decades, this striking figure kept remarkable company — sharing pages with the likes of Professor X, Scott Summers, and the enigmatic Karl Lykos across titles like Arma X and Marvel Série I. Rare in catalog count but rich in pedigree, Sauron is a compelling find for collectors with a taste for Bronze Age Marvel as filtered through one of Latin America's most celebrated comics publishers.
