Dormammu

"Dormammu! I've come to bargain!" "You've come to die! Your world is now my world, like all worlds!"

- Doctor Strange and Dormammu

Dormammu is an extremely powerful and malevolent primordial entity who rules the Dark Dimension. Dormammu convinced Kaecilius to use his power to destroy the Masters of the Mystic Arts and bring the Dark Dimension to Earth. However before Dormammu could complete his plans, he was confronted by Doctor Strange, who used the Eye of Agamotto to trap Dormammu in an endless time loop until he agreed to leave Earth and take Kaecilius with him.

Early Existence
The primordial creature known as Dormammu was a trans-dimensional life form that lived within the Dark Dimension. Wielding frighteningly tremendous supernatural power of apocalyptic proportions, Dormammu sought to conquer every dimension of the Multiverse, starting with Earth. To achieve this, he managed to employ contact with Kaecilius, a rogue member of the Masters of the Mystic Arts who had become disillusioned with the Ancient One's ideals. The two struck up a deal, with Kaecilius agreeing to gather the necessary items to free Dormammu from his domain.

Meeting Doctor Strange
"You will never win." "No, but I can lose again. And again, and again, and again, forever. And that makes you my prisoner."

After Kaecilius had destroyed two of the three Sanctum Sanctorums, Dormammu was free to fuse the Dark Dimension with Earth. Yet, a new member of the Masters of the Mystic Arts, Doctor Strange, flew into his dimension to confront him. Angered at this, Dormammu 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 of 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. Dormammu did this and kept his word, sealing the portal between the dimensions.
