Universo Marvel X

A six-issue Spanish-language series from Planeta DeAgostini, Universo Marvel X (2001–2002) reimagines classic Marvel concepts through a darker, more adult lens, blending familiar characters with a gritty, alternate-reality tone. Published during the early 2000s, it stands as a distinctive European take on the Marvel mythos, offering a self-contained storyline that explores the edges of the superhero genre without direct ties to mainstream continuity.
