The Ancient One (Marvel Cinematic Universe)

The Ancient One is the major supporting character of the 2016 movie, Doctor Strange. She was the Sorcerer Supreme and the leader of the Masters of the Mystic Arts, who mentored Doctor Strange in the use of magic following his accident. She was challenged by a former student, Kaecilius, who had become corrupted by the Dark Dimension and sought to bring Dormammu to Earth. The Ancient One gathered her army of Masters of Mystic Arts, but it was soon discovered that she had been lying to her students all these years and had been drawing her own power from the Dark Dimension, mortifying Karl Mordo. During one final battle, the Ancient One was fatally wounded and despite the best efforts of Doctor Strange and Christine Palmer, she accepted her fate and died.
