According to Marvel’s What If…?, Kang’s real MCU enemy is the Marvel Cinematic Universe, which is represented by the Watcher. Endgame established the multiverse, and Loki brought it to fruition.
At last, Loki and Sylvie were able to reveal who had set up the Time Variance Authority: a man named He Who Remains who had survived the multiverse’s conflict. When Sylvie killed He Who Remains, the multiverse re-emerged, and the end consequence was unavoidable. He had secured his power base by having the TVA prune branching timelines before new versions were produced.
As Kang The Conqueror, played by Jonathan Major, the MCU’s Phase 4 villain is considered to be one of the best yet. Kang is usually shown in comics as a 30th-century warlord who has traveled through time numerous times, fully confident in his own superiority, and intent to conquer everything that is, was, and ever will be in existence. When multiple Kang variations come into contact with one another and want to prove that they are superior to everyone else, the multiversal conflict will slowly re-ignite in the MCU’s Phase 4. While Loki has always enjoyed disorder, Sylvie’s murder of He Who Remains put him to shame.
The Watcher, a character from Marvel’s What If…?, is a direct competitor to the numerous Kangs. The Watcher in the Marvel comic books is a neutral observer who swears not to meddle. However. The Watcher shows up when events of cosmic consequence occur. This is a clever way of skirting his promise because his very appearance alerts superheroes to the gravity of the situation.
After swearing a holy pledge of non-intervention, the MCU’s Watcher was initially the same. However, he changed his mind when the multiverse was endangered by Ultron in What If…? episode 9. More than that, he shows no indications of reverting to his old ways, instead of renaming himself “Protector of the Multiverse” and purposely permitting the guardians to keep track of multiversal occurrences so he might use them again.
As a result of this, Kang the Conqueror and the Watcher will now be on opposite sides of the conflict. Some Kangs will undoubtedly wreak havoc across the multiverse, wiping out timelines in order to eliminate one another. If one version wins, they will only be able to guarantee their victory by following He Who Remains’ plan. This calls for cutting down the multiverse until only one timeline remains.
When compared to the Watcher, the MCU’s multiverse is extremely important to him, and he will do whatever to keep it that way. Even if that means cutting off entire branches, he won’t be happy about it. Every Kang endeavor is met with a strong pushback by The Watcher. The character not only has the capacity to halt the Kangs but also the eyesight to do so.
It’s becoming increasingly evident that each Marvel Disney+ TV series has a set of requirements they must meet. In other words, a list of boxes they must check off before they can contribute to the overall narrative of the MCU. With regard to What If…?, the Watcher’s character development – from observer to defender – appears to be the key premise. And now that it has been completed, he is positioned as a true power in the MCU.
