Observing the multiverse Following the creation of the
multiverse, the Watcher observes the
branching timelines that stem from the "Sacred Timeline". At first, the Watcher narrates the stories of
Captain Carter,
T'Challa Star-Lord, the assassination of the
Avengers, and when
Doctor Strange Supreme fell to darkness. While observing Strange's story, Strange begins to witness the Watcher and later, begs for him to save his universe that is collapsing, but the Watcher refuses to interfere due to his oath, leaving Strange alone. The Watcher continues his observations, which includes the
zombie apocalypse,
Erik "Killmonger" Stevens saving and befriending
Tony Stark, and
Thor adopting a party lifestyle.
Against Ultron He later observes and narrates the events of another universe, where
Ultron succeeded in wiping out life on his universe by uploading his consciousness in
Vision's body, and obtaining all of the Infinity Stones. Like Strange Supreme, Ultron also becomes aware of the Watcher after hearing his voice, and (to the Watcher's horror) intends to destroy and conquer the multiverse. As the surviving Avengers from Ultron's universe seek an artificial intelligence which can wipe out Ultron's program, the Watcher is attacked by Ultron throughout the multiverse. He attempts to fight back, but is overpowered by Ultron and forced to retreat. The Watcher is met with Strange Supreme, who convinces him that it is time to "break his oath" if he wants to stop Ultron. Reluctant at first, the Watcher agrees, and recruits Captain Carter, Star-Lord T'Challa, Prince Killmonger, Party Thor, and a Warlord version of
Gamora to become the
Guardians of the Multiverse. This group of Guardians ultimately defeats Ultron, resulting in Prince Killmonger and Arnim Zola eternally fighting for control of the Infinity Stones in a pocket universe watched by Strange Supreme, which Strange realizes was the Watcher's plan all along. The Watcher also transplants the Black Widow of the universe destroyed by Ultron to "a world that lost their widow".
Continued interference and standing trial In the third season, the Watcher continues to interfere in the stories of various heroes, and is put on trial by other Watchers due to his disobedience to their cardinal rule of noninterference. In the Fifth Dimension, the Watcher stands trial before the other three Watchers, the Eminence, the Incarnate, and the Executioner, while Captain Peggy Carter leads a team consisting of Kahhori, a grown-up Byrdie, and a Mjolnir-wielding Storm in stopping multiversal incursions. Carter and her team notice three shards from the Watcher's observatory and resolve to help him. After Carter is captured, a variant of Infinity Ultron agrees to help rescue Carter and the Watcher. In a flashback, a Watcher disciple named Uatu was recruited to become a full Watcher by the Eminence. In the present, the Watcher is placed on trial for his repeated interference, such as giving Doctor Strange Supreme the information he needed to recreate his destroyed universe, saving Riri Williams and Kwai Jun-Fan amongst others, as well as involving Captain Carter in his affairs. The Watcher and Carter are rescued by Ultron, who sacrifices himself to buy them time to escape. The Watchers give chase, attempting to erase them from existence, but the Watcher grants Carter's team the powers of a Watcher before Carter sacrifices herself to transport everyone to Strange Supreme's universe where Strange, having become the sentient consciousness of that universe, removes the powers of the Eminence, Incarnate, and Executioner. The Watcher convinces the humbled trio to learn by watching over life in this new universe. As they mourn Carter's death, the Watcher invites Kahhori, Byrdie, and Storm to join him in watching over the multiverse. == Reception ==
