The Time Variance Authority (TVA) first appeared in
Thor #372 (October 1986). Created by
Walt Simonson and
Sal Buscema, the TVA originally paid homage to long-time Marvel writer/editor and continuity expert
Mark Gruenwald: the TVA staff were all visually designed as clones of Gruenwald (the classification system for alternate realities—the
Marvel multiverse—was devised, in part, by Gruenwald). Simonson had also took inspiration for its initials from the
Tennessee Valley Authority, a federally-owned electric utility company that his own father had worked alongside in his birthplace of
Knoxville, Tennessee. In July 2024,
Marvel Comics announced the five-issue comic book series
TVA, written by
Loki season two writer Katharyn Blair with art by Pere Perez, to debut in December 2024. The series sees the comics' version of the TVA blended with the one established in the
Marvel Cinematic Universe (MCU) along with the comics debut of some MCU characters.
Antecedents Squadron Sinister/Squadron Supreme Writer
Roy Thomas and Sal's brother, artist
John Buscema, had previously explored the concept of a Marvel multiverse with Marvel's evil
Justice League correlates, called the
Squadron Sinister, in
Avengers #69 (1969). Thomas later introduced a heroic version of the Squadron Sinister named the
Squadron Supreme, which first appeared in
Avengers #85–86 (February–March 1971), and which was co-created with John Buscema. In 1985–1986,
Mark Gruenwald wrote a
deconstructionist multiverse storyline featuring the Squadron Supreme in a self-titled twelve-issue
limited series.
Captain Britain and the Dimensional Development Court The concept of a timeline monitoring organization had previously been explored in a
Captain Britain story arc originally published in the
Marvel UK series
The Daredevils #6–8 (1983). Written by
Alan Moore and
Alan Davis, Captain Britain is brought outside of time to the Supreme Omniversal Tribunal in Eden Place to testify before Lord Mandragon, Majestrix of the Dimensional Development Court, on behalf of the former majestrix, Opal Luna
Saturnyne. Saturnyne is accused of failing to protect the
multiverse from the creation of a deviant version of
Earth-238. Before Captain Britain's testimony, Mandragon declares that the Earth-238 universe must be "removed" from the multiverse before it destroys the continuums of the other universes. Saturnyn's legal counsel, a faceless being referred to as Lord Chancellor, objects, as the destruction of the Earth-238 universe will destroy material evidence of Saturnyne's innocence. Lord Mandragon overrules the defense's objection, citing Ominversal Writ clause 723-801-(d). He then proceeds to remove the dangerous deviant
timestream using crystal technology. It is revealed during the trial that the prime Earth that exists in Marvel Comics is
Earth-616. Because of this story, Alan Moore is usually credited with naming the mainstream
Marvel Universe "Earth-616." However, Alan Davis has said that it was invented by
Dave Thorpe, the previous writer of the UK-published
Captain Britain stories.
TVA as homage to Gruenwald and Captain Britain While Captain Britain's 1983 story arc does not mention the Time Variance Authority, the Dimensional Development Court contains elements that were plainly
retconned by Walt Simonson and Sal Buscema and in subsequent incarnations (such as the TVA employees—chronomonitors—functioning and appearing in new universes in the same manner as the
Captain Britain Corps). According to
Mark Gruenwald's widow Catherine, Gruenwald's 1985
Squadron Supreme limited series was the work about which he was the proudest. ==Fictional background==
