In this post, I'll compile news about the MCU and comic book crossovers
At 11:40 Katharyn Blair (Loki Season Two co-writer) specifically says that it was an exec at Marvel who had an idea to do a TVA comic, but that it was Jordan D. White, Marvel Comics editor who listened to her pitch and let her run with it.
I love this idea,” shared Feige. “It’s just as cool for us to see our work in comics as it is to bring the work of comic book creators to the big screen.
The Marvel.com article also specifically mentions that Feige approved the crossover.
The reason these crossovers are possible is that Feige has already been promoted from President of Marvel Studios to CCO of Marvel Entertainment in 2019.
So he had CCO authority to kill off Ms. Marvel in 616 and retcon her as a mutant.
Back when Feige was just the president of Marvel Studios, he once said that because the TV shows were produced by Marvel Television (Pre-Disney+) rather than Marvel Studios, it would be difficult for the crossovers to keep up with the pace of the showrunners writing the shows.
Also, several MCU tie-in comics have gone non-canon.
But now that Feige has been promoted to CCO of Marvel Entertainment, not only is there better communication between the divisions, but a Marvel Studios employee revealed that Marvel Comics is also collaborating, and that stories from the comics won't be ignored on screen.
TVA Comics revealed that Captain Carter had joined TVA, that would explain where Guardians of the Multiverse stole reset charges from
As an aside, someone mentioned the Spider-Verse in this thread before, and it reminded me of something
I don't know if it will help, For now I brought this
ATSV's Jessica-332 has already appeared in the comics, and the crossover with Earth-1048 has been canonized in both media
As an aside, in the commentary for the ATSV, it was mentioned that Miguel referenced Earth-001 (Loomworld) when creating the Spider Society's facility.
The ATSV also featured the Ultimate Tarantula from the comics' Earth-1610.
(Previously, characters like Steven Rogers (Earth-1610) were resurrected for unknown reasons when the Ultimate Universe was restored)
For the record, there was a lot of implications in the comics at the time that Earth-1610 would return, but when Donny Cates, who was originally slated to write Ultimate Invasion, was in a car accident, Jonathan Hickman ended up creating a new universe called Earth-6160.
In spite of that, Jimmy Hudson Jr. (Earth-1610) was apeared in TVA comics so that might be something, despite the fact that he was already displaced to Earth-616
Especially both 6160 Logan and 1610 Logan appeared in recent comics
