1. Thunderbolts (Earth-199999; a.k.a. Prime MCU) ending, the Fantastic Four from Earth-828 arrives.
2. The Fantastic Four: First Steps (Earth-828) ending, Doctor Doom showed up
3. There's going to be a The Fantastic Four: Doomsday
4. Then there's going to be an Avengers: Doomsday
In Avengers: Doomsday (presumably happening on Earth-199999), the Fantastic Four (Earth-828), the X-Men (from what Earth are they again from?), and the new Avengers (a.k.a. Thunderbolts), are going to team up to battle Doctor Doom.
That much is clear.
So …
A. Is it safe to assume that Doctor Doom kidnapped Franklin fom Earth-828 and brought him to Earth-199999? Which led to the Fantastic Four arriving on Earth-199999 as shiwn in the ending of the Thunderbolts?
B. And for whatever reason, the X-Men also arrived on Earth-199999 and joined with the Avengers and the Fantastic Four?
C. It won't end well. Doctor Doom escaped to the TVA to kill Loki.
D. Earth-616 is low-tech as far as Earth-828 is concerned.
E. So, the new Avengers (Thunderbolts), the X-Men, and everyone else, joined The Fantastic Four in "The Fantastic Four: Doomsday" because it is only there that they can build a teleportation device that can go to the TVA.
Once they reach the TVA, well, they hunt Doctor Doom.
However, when they arrived at the TVA, they were too late, TVA-Loki is dead. The one sitting on the throne is now Doctor Doom.
Then comes, Avengers: Secret Wars
