Producers of both Loki and the third Ant-Man film have repeatedly clarified that, while He Who Remains and Kang the Conqueror are variants of the same person, their experiences have made them entirely different characters.
There's an interesting theory that the Council of Kangs didn't refer Quantumania Kang as the exiled one, but He Who Remains, which it almost makes sense since he isolated from the other universes after winning the Multiversal war, with Centurion being so salty that he didn't get the chance to kill him since Sylvie did ...
For all we know, he has a very different origin story than he does in the comics. In the Marvel Cinematic Universe, it could easily be revealed that The Watcher is a version of Kang who decided to observe the entire multiverse instead of conquering it.
During an adventure in Limbo, it is revealed that Immortus is the future incarnation of both Kang and Rama-Tut. While attempting to travel to the time of the Crusades, Hawkeye accidentally comes across Kang, sending both to the Old West.
Nathaniel Richards was a scientist from the 31st Century who came into contact with alternate universes and other versions of himself. When some of these Variants attempted to conquer other realities, a Multiversal War ensued, which he ended by weaponizing Alioth.

What is Kang's real name?
Kang's real name is Nathaniel Richards, and he is a direct descendant of Reed Richards, the leader of the Fantastic Four (the character that John Krasinski played in Doctor Strange in the Multiverse of Madness).
Even Loki Season 1 danced around actually naming Kang, with the eccentric He Who Remains instead alluding to the character by calling himself a "conqueror." This is why none of the characters have spoken the name "Kang," as they are only acquainted with "He Who Remains," and his variants.
Who is stronger Kang the Conqueror or He Who Remains?
Despite the shocking level of power expressed by Kang the Conqueror in Ant-Man and the Wasp: Quantumania, Loki season 1 implied that He Who Remains was, in fact, stronger than the Conqueror and all his other variants.
In the Comics. Although Kang made his MCU debut as a variant known as He Who Remains, that wasn't how he got his start in the comics. (In fact, He Who Remains is a different character altogether.) But he didn't exactly appear as Kang the Conqueror either.
Based on Ant-Man and the Wasp: Quantumania alone, it certainly seems as though He Who Remains was the more powerful and capable variant, having succeeded where the exiled Kang epically failed.
Stepping into the Citadel at the End of Time, Loki and Sylvie meet He Who Remains (Jonathan Majors), a version of time-hopping comic villain Kang the Conqueror.
Jeffrey Wright reprised his voice role of the Watcher in I am Groot season 2, episode 5, "Groot and the Great Prophecy," after debuting as the all-powerful, cosmic being in Marvel Studios' What If...?.
Summary. He Who Remains, the first Kang variant in the MCU, was not a villain but actually had noble intentions in maintaining the "Sacred Timeline" to prevent timeline chaos.
He is so powerful, and with the brains and technical know-how to match, Kang could wreak multiversal havoc whenever he pleases. One of the main reasons Kang is a much larger threat than Thanos ever could be is because of his ability to see time to know the future, past, and present all at once.
Despite telling the protagonist duo that killing him will leave another of his variants in his place, Sylvie murders He Who Remains - a decision that, as the show's ending reveals, places Marvel villain Kang in charge of the TVA and thus the MCU timeline, seemingly.
In Ant-Man and the Wasp: Quantumania, various versions of Kang are revealed, including Immortus, Rama-Tut, Scarlet Centurion, and more. The Council of Kangs, taken directly from Marvel Comics, makes an appearance in the film's mid-credits scene, introducing even more unique Kang variants.
Unfortunately, this didn't work, and Ahura ended up killing Kang and assuming his position, leading to an epic and heartbreaking battle between Ahura and the Inhumans.
Immortus is established as the most powerful version of Kang. Immortus appears in the end credits of Ant-Man and the Wasp: Quantumania rocking his signature headpiece and instead of having a blue mask like Kang the Conqueror instead has a blue face.
He Who Remains did appear to have some genuine regret for betraying Renslayer in this way at the very least. It was later revealed that He Who Remains' seeming acceptance of his fate was simply another manipulation, having set things up so that killing him and unleashing the Sacred Timeline would destroy everything.
The one who remains gave Loki the time slipping ability by granting him access to the TVA (Time Variance Authority) and its technology, particularly the Time Twister, which allows individuals to navigate through different timelines and realities.
Is Ant Man 3's Kang the Conqueror the same as Loki's He Who Remains?
Speaking with Empire, Ant-Man 3 director Peyton Reed described Kang the Conqueror as an “an all-timer antagonist,” noting that the time-traveling villain will be "very different" from He Who Remains: “Kang The Conqueror in our movie is a very different character.
Nathaniel Richards is a fictional time-traveling scientist appearing in American comic books published by Marvel Comics. He is the father of superhero Mister Fantastic of the Fantastic Four and is the namesake of his descendant, the futuristic villain known as Kang the Conqueror.
