Dormammu made his first appearance in *Strange Tales #126* published in 1964, created by writer Stan Lee and artist Steve Ditko. An ancient interdimensional entity, Dormammu is the ruler of the Dark Dimension and often serves as an adversary to Doctor Strange, Marvel's Sorcerer Supreme. Over the decades, Dormammu's character has evolved from a simple villain to a complex entity representing cosmic horror and existential threats. He feeds on the souls of the living and seeks to spread his influence through dimensions, often pitting himself against various heroes of the Marvel Universe. His role has increased significantly post the events of the *Infinity War* in comics and gained newfound popularity thanks to his portrayal in the *Doctor Strange* film released in 2016, where he was voiced by Benedict Cumberbatch. Across all media, Dormammu embodies the archetype of a mighty, nearly invincible villain whose ambitions transcend the known universe, illustrating themes of power, corruption, and the struggle between good and evil.
