Chthon

Chthon is one of Marvel's Elder Gods, an immensely powerful demon sorcerer who shaped Earth's earliest dark magic. He inscribed his arcane knowledge into the mystical Darkhold scrolls before being banished to another dimension, leaving that cursed tome as his instrument of influence.

Few villains in Marvel's Bronze Age arrived with the cosmic menace of Chthon, the ancient demonic entity who first crawled into readers' imaginations in The Avengers #186 in 1979, courtesy of David Michelinie, Mark Gruenwald, and John Byrne. A creature of primordial darkness, Chthon has spent nearly five decades haunting the margins of Marvel's mystical corners, turning up most frequently in the sorcery-soaked pages of Doctor Strange, Sorcerer Supreme and The Mighty Avengers, where the stakes are always cosmically high. The company Chthon keeps tells you everything about his weight in the Marvel Universe — sharing pages with Wanda Maximoff, Captain America, Iron Man, and Spider-Man signals a threat that demands Earth's mightiest to take notice. With a key-issue debut and a presence stretching all the way to 2026, this is one of Marvel's most enduring forces of ancient evil, well worth tracking down for any collector who loves their darkness old, powerful, and genuinely unsettling.
