Since the Loki series began they have kept the secret of who was behind everything, but in the last episode they revealed it.
After the fifth episode of the series of Loki, everything suggested that Kang, the conqueror, also know as Immortal he was the big villain behind TVA. Something that has been confirmed in the sixth and last chapter that has already been released in Disney Plus. Although they do not get to say his name, the character played by Jonathan Majors it is Nathaniel Richards, a descendant of Reed Richards from The Fantastic Four and that will appear in the movie Ant-Man and the Wasp: Quantumania (2023).
The series of Loki began by introducing the Guardians of Time like those who had created the TVA to preserve the sacred timeline. But we were able to verify that those beings were simply mere robotic puppets and that there was something else behind it. So Loki (Tom Hiddleston) Y Sylvie (Sophia Di Martino) go to the end of time where all variants are eliminated by a terrible smoke wolf. But in that place they discover that there is still someone who manages everything and who hides in a castle. So they go into that place to discover that Kang is the great villain.
This is his story:
In the Loki series, Kang reveals that he is a 31st century man from Earth who discovers that different universes exist and establishes contact between other versions of himself. At the beginning everything goes well and there is harmony between them, but some want more and want to conquer everything, so a war begins that leads to total chaos. A Kang discovers the creature Alioth and thanks to that he begins to correct the variations creating the sacred timeline. This eliminates free will, since he has seen everything and knows everything and has written down everything that has happened and will happen.
But the arrival of Loki and of Sylvie causes a drastic decision to be made between two options. Since they can kill Kang and cause chaos to return in the multiverse or they can put themselves in command of the TVA and rule everything.
Sylvie decides to kill Kang and causes chaos.
War breaks out and Kang He stands as the great leader of the TVA, since we can see his sphinx where the one of the Guardians of Time used to be, that means that he is no longer hiding. These events give way to the second season, so it will take a while to find out how things continue. Although it is confirmed that Kang will return Ant-Man and the Wasp: QuantumaniaSo the Quantum Realm may be out of control of this villain, so they will have to make the whole story fit. For now, we do not know if they will premiere the second season of the Loki series before this film that is scheduled for 2023.
