Disney+ Loki TV series may also hint at the new owner of the Avengers Tower. During the show, Loki is transported to an alternate reality where the Avengers Tower is no more. At the end of the fourth episode, we see the Tower destroyed, but instead of there being an "A" on the building, it reads, "Qeng Enterprises." Interestingly enough, Qeng Enterprises is a company that buys Avengers Tower from Stark Industries in the comics. The company is owned by a businessman named Mr. Gryphon, who is a variant of Nathaniel Richards, aka the supervillain Kang the Conqueror.
We saw a version of Kang in Loki named He Who Remains. Kang is also expected to appear in the upcoming film, Ant-Man and the Wasp: Quantumania, which will hit theatres in 2023.
While the true identity of the Avengers Tower remains a mystery, it seems we might have an answer soon with all the new Marvel films and TV series coming out.
