In 1978’s Thor #282, by Mark Gruenwald and Ralph Macchio, the Time-Keepers have been launched as creations of He Who Remains, the final remnant of the earlier universe, as a solution to information and form the new multiverse. His first try didn’t go so nice – the Time-Keepers have been somewhat bit genocidey, destroying a number of completely different realities. So Thor traveled again in time and satisfied He Who Remains to retry, and his efforts cut up the timeline and created the Keepers, who restricted their work to some mild, Avengers-related pruning.
Kang the Conqueror
Through the years they have been in cost of the TVA, the group they created to assist police the timeline, and most of their work that we learn about was spent messing with Thor and the Fantastic Four. They additionally ultimately subcontracted to Immortus, selecting Kang the Conqueror’s future self to assist execute their timestream gardening and placing them in common battle with the Avengers. They would ultimately come to blows with Avengers from varied factors of their subjective timelines who, allied with Kang, fought to save lots of Rick Jones and the Destiny Force from Immortus and Time Keeper deletion. In that battle, Kang would kill the three space lizards.
Loki and Secret Wars
The factor is, in the comics we’re on our eighth Marvel multiverse.
There is loads of metaphysical mumbo jumbo concerned, however Secret Wars marked the finish of the seventh multiverse and the starting of the eighth. The colliding realities ultimately collapsed into Battleworld, the lone planetoid current in a void of nothingness, comprised of bits and items from 50ish universes saved by Dr. Doom and Doctor Strange (and the Molecule Man), and mushed collectively to maintain humanity alive. Molecule Man ultimately gave the energy he was letting Doom use to Reed Richards, and Mr. Fantastic recreated the multiverse with the assist of his household.
The collapse of the multiverse created circumstances by which the First Firmament, the personified essence of the first multiverse, might break the chains it had been shackled in by the Celestials, and led to it attempting to devour the new multiverse. They have been ultimately stopped by Galactus Life Bringer and his Ultimates, led by Monica Rambeau and Black Panther. Al Ewing’s Ultimates is a visit, y’all.
You’ll word that the Time Variance Authority has nothing to do with any of that above nonsense. The level right here is that the comics TVA is targeted completely on sustaining the timeline of their nook of the multiverse, and never heading off potential issues that might come from a branching timeline.
