Darwin

Armando Muñoz is a Marvel mutant whose body instinctively adapts to survive any threat or environment, a power that manifested from birth. He eventually joined the X-Men and later X-Factor Investigations as one of Marvel's most uniquely resilient heroes.

Born into the Modern Age of Marvel Comics, Darwin made their striking debut in Ed Brubaker, Trevor Hairsine, and Scott Hanna's X-Men: Deadly Genesis #2 (2006), arriving as part of a revelatory story that shook the foundations of X-Men history. Over nearly two decades — with appearances stretching from 2006 all the way to 2025 — this character has proven themselves a quietly enduring presence across titles like X-Factor and World War Hulk: X-Men, sharing pages with heavy-hitters like Jamie Madrox, M, and Monet St. Croix. With a key issue already to their name and 61 catalogued appearances, Darwin is the kind of character that rewards the curious reader who digs deeper into Marvel's mutant tapestry — a gem of the modern era with real staying power.
