History
Dormammu is a resident of the Dark Dimension and wishes to merge all existing universes with it. Despite his sinister plans, a group of Zealots mistakenly believes that Dormammu should be allowed to merge Earth with the Dark Dimension, believing that this would eradicate time and death and would thus grant eternal life. The Zealots, led by Kaecilius, contact Dormammu who grants them strength through the powers of the Dark Dimension. He tasks Kaecilius with destroying the sanctums of magic in Hong Kong, London and New York to allow Dormammu to spread the Dark Dimension on Earth. Kaecilius succeeds to destroy the three Sactums, creating a portal in Hong Kong through which Dormammu spreads the Dark Dimension on Earth.

However, Dr. Stephen Strange (a new member of the Masters of the Mystic Arts) reversed the time by the use of the Eye of Agamotto and the Infinity Stone inside it, and then flew into his dimension to made to negociate with him. But Dormammu refused and quickly killed Strange, but to his confusion, Strange appeared again, repeating himself. Multiple times, Dormammu killed Strange until the Doctor revealed that he used the Eye of Agamotto and the Infinity Stone inside it to create an infinite time loop, with them spending eternity together in a endless cycle. Eventually, Dormammu began begging Doctor Strange to end the time loop, which he did, on the condition that Dormammu banishes himself and the Zealots from Earth for eternity. Dormammu reluctantly kept his word, sealing the portal between the dimensions and taking the Zealots with him in the process by sucking them into the Dark Dimension.

Trivia

 * Rather than being wreathed in flame like in the comics, Dormammu appears to be a being of pure shadow and darkness but with bright purple eyes, although he does appear to have red "shadows" surrounding his entire body - this may in fact represent the "flames".
 * Despite being by far the most powerful villain in the movie (and possibly the strongest character in the entire Marvel Cinematic Universe), Dormammu is listed as a central character because he has far less screen time than Kaecilius, making him the Bigger Bad instead of the Big Bad.
 * It was Benedict Cumberbatch's idea to perform motion-capture for Dormammu, as he felt that the character should be an evil reflection of Doctor Strange.
 * Before the movie was release, he was promoted as the main antagonist.
 * In-universe, Dormammu's physical resemblance to Strange is a form Dormammu assumed to mock Strange.
