Arc 15Dormammu and Hela
Xia Yu helped the Ancient One survive, then defeated and imprisoned Dormammu after Doctor Strange trapped him in a time loop. A year later, Odin revealed Hela’s return, and Thor, Loki, Xia Yu, and Hela went to Asgard as Heimdall uncovered the location of Asgard’s Source.
- Xia Yu helped the Ancient One return to life, and she later gave up the Time Stone and her role as Sorcerer Supreme.
- Doctor Strange used the Time Stone to trap Dormammu in a repeating ten-minute loop, while Xia Yu attacked Dormammu in the void and pursued him through the Dark Dimension.
- Xia Yu exhausted Dormammu’s power with mechanical soldiers and captured his surviving soul fragments with the Ancient One’s help.
- Stan Lee warned Xia Yu that fate had strayed from its original course, and Xia Yu absorbed some of the Time Stone’s power before Odin summoned him a year later.
- Odin revealed that Loki had impersonated him and warned Thor and Loki that their sister Hela would threaten the Nine Realms.
- Hela attacked Xia Yu, who fought her at sea before Thor decided to bring her to Asgard and the Bifrost transported them there.
- Heimdall told Thor that Asgard’s people were safe and showed him the hidden location of Asgard’s Source beneath the dungeon.
