The Time Variance Authority (TVA) is a fictional organization appearing in American comic books published by Marvel Comics. It is depicted as a group of timeline monitors tasked with preventing certain timelines that are deemed too dangerous to the Multiverse from existing. Time Variance Authority.
Every bombed branch represented an entire universe, and billions upon billions of lives on every planet, eclipsing the scale of Thanos' Infinity War snap multiple times over. Thanos wiped out half of existence, but the TVA just wiped out 100% of existence in any number of entire universes.
The Time Variance Authority (TVA) acts as the judge, jury, and executioner behind any temporal anomalies in the multiverse. A bureaucratic agency, their primary function is to monitor and regulate all realities and timelines. They are based in the Null-Time Zone dimension.
Loki was recruited to work at the Time Variance Authority. Mobius M. Mobius instructed him to learn about the TVA and Loki worked at an office, where he read through TVA files and watched training videos.
He said he took control of Alioth, the beast that consumes everything that was pruned from branch timelines and used it to win the war. The once and future Victor Timely said he created the TVA to maintain the Sacred Timeline and prevent other Kang variants from arising.
At the end of season 1, He Who Remains also explained that he'd become tired of living, and presented a choice to Loki and Sylvie: They could take his place as administrators of the TVA, policing the timeline to prevent multiversal war — or they could give in to Sylvie's goal and kill him, knowing it would unleash ...
Another reason why Kang might want to keep the TVA human is that he needs a group that is willing to be loyal to the Timekeepers. The Timekeepers were presented as mystical and powerful otherworldly beings and humans may be more likely to believe that they control everything due to their mysterious origins.
Deadpool is courted by the TVA to become a hunter but quickly clashes with them, leading to violent confrontations. Deadpool's previous time-traveling and universe-hopping antics in Deadpool 2 set up the TVA's awareness of him.
Citing the Marvel Visual Dictionary, this theory explains that Odin used magic to make Loki seem Asgardian. However, Odin must have used stronger magic than a simple illusion. Otherwise, Loki would have turned blue in Loki when he entered the Time Variance Authority (TVA) Office, where magic and powers did not work.
In the Deadpool 3 trailer, agents from the TVA knock on Wade Wilson's door on his birthday. It's unclear exactly what they want, but they do take him to see Paradox.
Loki's first season established the TVA as a place outside of normal time and space. He Who Remains and his servants didn't age over eons inside the Machiavellian bureaucracy. Mobius wasn't even sure exactly how long he'd been protecting the Sacred Timeline, since “time moves differently” at the TVA.
The Tennessee Valley Authority is governed by a nine-member part-time board of directors, nominated by the president of the United States and confirmed by the Senate. A minimum of seven of the directors are required to be residents of TVA's service area.
But the TVA was not powerful enough to overpower. Odin's magic and cancel Odin's magic from Loki. Which proves how powerful is Odin. TVA can stop Infinity Stone's power, but not Odin's power.
Perhaps at some point in his past, Thanos crossed paths with the TVA or heard about them in some way. However he found out about them, he would have discovered the sacred timeline and could well have seen the Snap in his future.
The TVA headquarters may have been protected with runic symbols, similar to Agatha's basement, albeit on a far larger scale. In this protective field, the Infinity Stones would lose their power.
When Sylvie kicked Loki through the Time Door he went to the same TVA's own past. That's why Mobius and B-15 didn't recognize him at the end of season one. That's also why Loki saw those massive statues. Earlier in the TVA's history He Who Remains did not hide his identity behind robot Time-Keepers.
In his exile, Odin apparently thought over all the acts he had done and likely felt remorse over them, as he showed no hostility towards Loki and even noted Frigga would be proud of him. He also admitted that he truly loved both of his sons and expressed remorse for failing to stop Ragnarök.
Loki was born a Frost Giant and abandoned as an infant by his father Laufey, only to be found by Odin during an invasion of the realm of the Frost Giants in Jotunheim. Odin used magic to change Loki to look like an Asgardian and raised him as a son alongside Odin's biological son, Thor.
In other words, while the Avengers did create new branches in the timeline, they then pruned them, in a fashion. The TVA chose not to interfere in the Avengers' actions because they knew these new branches would be erased by the Avengers themselves.
Although Deadpool 3 has the premise to welcome Loki, it is unclear if Loki is willing to appear. His time-slipping ability initially allowed him to pop up in whatever timeline he pleased. However, Loki's ending seemed to insinuate he was trapped in a new role in the MCU.
But how would the TVA defeat Thanos? Easily. For one, they have time sticks that can erase any living beings. The fight would end rather quickly, as Thanos would be fairly easy to track down.
The TVA is kind of both hero and villain, depending on your perspective. He Who Remains tells Loki the TVA is good because it's keeping out Kang variants and preventing multiversal war from happening.
