Alioth

Piecing together clues left over the course of the series — such as the presence Ravonna Renslayer, his association with Alioth and a home base that exists outside of time — it’s pretty clear that He Who Remains is a version of Kang the Conqueror.

The newly pruned Loki quickly learns that the No. 1 priority for his fellow Loki variants in the void is to stay alive by steering clear of Alioth, a giant monster that descends from the sky.

Alioth is also an incredibly powerful — if obscure — creature in the comic books.

Alioth feeds on temporal energy and can absorb time travelers as well as entire time periods near the portion of the dimensional plane it occupies.

Described by Boastful Loki as “a living tempest that consumes matter and energy,” Alioth is what makes sure whatever is sent to the end of time never escapes.
