The Time Variance Authority, also the brainchild of Walt Simonson with fellow artist Sal Buscema, was first introduced in Marvel Comics in a 1986 issue of Thor, coincidentally.
Created by writer and artist Walt Simonson, the Honorable Mr. Mobius “Moby” M. Mobius is a black-haired, mustachioed bureaucrat who works for the TVA (Time Variance Authority) as a senior executive of middle management.
As a recent Loki trailer sheds light on, the agency closely monitors the multiverse’s individual realities to make sure things, including time itself, run smoothly.
Much like his tampering with events of 2012’s The Avengers in Loki’s Avengers: Endgame cameo, the TVA has cracked down on a few bumps in the space-time continuum in the comics, some created by even the most heroic characters.
