I think Kister has gotten good enough at the bread and butter of TMC that with the script being worked on A24 could be a great way to launch this film as an indie religious-horror piece.

Multiverse Saga:

• Avengers Doomsday: Doom is destroying universes for the good of the multiverse and thinks a doomsday is near, so he salvages the multiverse into Battleworld, meanwhile a small group of heroes escape to the Life Raft and are left unaffected by Dooms Battleworld shenanigans.
• Avengers Battleworld: A whole film dedicated to the Life raft heroes surviving on Battleworld, Doom has achieved everything he's wanted and spends much of the film getting screentime is a dictator making bargains and exchanges with enemy territories, there'd be multiple variant-themed continents that get fleshed out in this film. Film sets up a secret war to overthrow Dooms governance.
• Avengers Secret Wars: War breaks out on Battleworld and Empire Doomstadt begins to collapse as a society and a government, Doom is furious and the film ends with the heroes trying to kill Doom and safe the multiverse, but Doom will not allow this to happen and destroys Battleworld, and he merges the leftover fragments of the multiverse to create an "Ultimate MCU" Timeline where there is no multiverse and nobody remembers it, but there's mutants, avengers, Fantastic4, aliens and a couple Spider-People all in one universe. Doom will still be alive but he won't remember the multiverse saga, he will simply be ruling over Doomstadt in Latveria and he will terrorize heroes in the Mutant Saga, presumably with a different actor!

Mutant Saga:

• Fantastic Four 2: This will be about the Annihilation Wave and feature Captain Marvel, Doctor Doom will feature in a small post-credit scene.
• Xmen 1: A simple introductory film about Mutants and the X-Mansion, Professor X will be developing his team of gifted students, there will be minor B-tier villains but the chemistry being built between characters will be far more important. Magneto will be seen only on TV as a controversial but beloved public speaker who acts as the leader of Genosha.
• Magneto Solo Film: Magneto will have his own WW2 Solo film about being a Jewish holocaust survivor and the oppression that the Germans held over mutants, viewing them as freaks of nature and tormenting them in public humiliation rituals, live executions and even freak circus acts. This film sets up Magneto as an anti-hero for the Xmen reboot.
• Black Panther 3: The villain of this film will be Doctor Dooms daughter Valeria, she will be attempting to conquer Wakanda for their vibranium and technology with the help of Doombots, Victor will only cameo until the very end of the film when Wakanda has been conquered successfully.
• Xmen 2: A film about The Mutants truly using their chemistry to assemble both a team and a family, their first villain will be Mr. Sinister who wants to abduct Mutants to make the perfect race, Magneto will visit the X-Mansion as a supporting character who is a good friend of Prof. Xavier. The post credit scene of this film will be an unseen flashback to Mr. Sinister discussing how has already abducted some specimens for Doom to study while they communicate over a hologram and Doom speaks of how, he is pleased that these mutants can benefit his work.
• Fantastic Four 3: The end of their trilogy, this will culminate in a classic Fantastic 4 versus Doctor Doom story, Victor Von Doom wants to expand his territory beyond Latveria by invading foreign countries and he plans to start by invading Manhattan so he can take over the Southeastern corner of the US until he can expand his influence, this film will culminate in Dooms first stalemate and he retreats until the next film.
• Xmen 3: A film with themes of discrimination and segregation, Bolivar Trask reaches out to congress and passes the law that mutants are illegal aliens and must move to Genosha while his sentinel's shoe mutants onto foreign ground and kill many of them. The film will end with a post-credit scene of Trask stepping out of his private jet on Latverian soil to discuss how the Mutants have been successfully relocated, Doom will be pleased and talk about how his plan can commence, Trask will ask for his share of money that they agreed upon, Doom refuses, Trask crashes out and pesters Doom till he gets his neck snapped.
• Xmen4: Doctor Doom has finished conquering Wakanda and used it's advances to benefit his technology, now he intends to takeover Genosha so he can study Mutant DNA to better the human race. This film will be about a rivalry between Magneto and Doctor Doom, fighting over Genosha, the film will end with a rematch between the Fantastic 4 and Doctor Doom, after a tough battle in the fallout of Genosha the FF will lose and Reed will talk with Doom about how together they can make a better world without his hubris, and Victor can have a family, for the first time ever Doctor Doom shows a glimmer of kindness, saying that although he has never agreed with Reed he respects him as an inventor for mankind and a mentor to his family, and he will honor their legacy in death, when suddenly Magneto takes this opportunity to kill Doctor Doom with the surrounding debris of Genosha.

What does this story accomplish? It makes Doctor Doom the irrefutable big bad of not just the multiverse saga but the MCU in general, he will have come out victorious nearly 2 sagas in a row, I think it really fits Doom to be so formidable that he could only lose to his own hubris, he already conquered the multiverse, but that wasn't enough, he had an insatiable hunger for complete domination, because no world is perfect without his control.

I really do feel like Spiderman: Brand New Day could be such a perfect puzzle piece to the Born-Again series, we have Spiderman fighting The Hand in prison after Matt has been sentenced and Punisher is already a supporting cast-member.

I think since Matt is an ex-lawyer he will respect the law and do his full sentence, but he will assist Spiderman in defeating The Hand during their prison-break attempt on some villain. All we need for a full-circle connection is to replace Tombstone with Kingpin, and yes, he can fight Spiderman, he has access to technology capable of regenerating an eyeball, I think he can afford a super soldier serum.

Loki Series: The death of He Who Remains caused too many branching timelines without moderation, foreshadowing a natural death of the multiverse since it will eventually self-destruct from being crammed with too many universes.

Doctor Dooms motive: Doom knows about the consequences of He Who Remains dying, from his perspective, time is running out and the more timelines that branch the closer a doomsday event is which would culminate in the death of everything, so in fear of this possibility he will be destroying universes, with less universes this will delay the inevitable Doomsday and buy him time to find the God of Stories, Loki.

Why Doom needs Loki: Doom respects Loki but views him as a half-measure, merely delaying the inevitable death of the multiverse, so he intends to take his powers and create Battleworld by flooding all recoverable timelines into the TVA Void.

Why Thor is terrified: Right or wrong, Doom destroyed countless timelines in his path for salvation, and he will try to destroy Earth-616, and he has destroyed many like it.

Now this may sound farfetched, many of you may be asking, "why would Marvel destroy their own brand?" or saying "Doom kills everybody? Sound depressing". and I would like to share why I think Dooms victory would not only be shocking but set the stage for another decade of stories!

Doomsday: After the death of He Who Remains countless branching timelines have been created causing irreversible damage to the multiverse, its collapse is imminent, marking the beginning of a doomsday event. Doctor Doom will destroy universes to buy himself time before time runs out, because he is trying to locate the God of Stories so he can take his thrown and create a single timeline. Doctor Doom will have destroyed a couple universes by the end of the film a multiversal doomsday elapses, the destruction of every known universe has begun, and Doom will have bought himself just enough time to save the multiverse by using what universes remain to create Battleworld out of the TVA Void.

Secret Wars: Basically, it would be another Avengers Endgame situation, Doom wins, the heroes want to reverse his actions by undoing Battleworld, all of existence under the fingertip of one totalitarian madman with a god complex, the heroes despise the whole idea of Doctor Doom as both an emperor and a god to this world. After Doctor Doom realizes the heroes are trying to undo everything he has set out to do, rip him from his rightful throne, destroy his kingdom, he will be furious and realize as long as there are those who remember what was, they will never be able to appreciate what will be, Battleworld. Doctor Doom will destroy Battleworld out of last resort frustration and create an "Ultimate Universe" where nobody will remember the multiverse, not even him.

SW Epilogue: We will get a glimpse of the Ultimate Timeline, we will see Spiderman swinging past the Baxter Building, students flourishing at Xaviers Academy, a statue in remembrance of Captain America and finally the last shot we will see is a pleased Doom looking over Latveria, he won. The MCU will get soft rebooted by Doctor Doom, some things will stay the same in this universe, some will be changed, like how mutants have always existed, fantastic four too!

Now I have a sneaking suspicion this take could get bombed into oblivion, and that's okay, because The Punisher is easily the most fan favorited character besides Daredevil in the series, he's a top 5 Marvel character for me personally.

but you guys got to think... he's had 2 solo seasons, a solo film, will have already played a major role in at least 3 seasons of Daredevil and he's going to be an important supporting character in Brand New Day. This is more than enough to finish his story, he's a beloved character for a good reason but what's left to do with him?

I think a satisfying conclusion would be for The Punisher to be killed by an equal force after achieving his goals, and what better opponent than Daredevils most formidable rogue? This is a matchup that Bullseye actor himself, Wilson Bethel has made clear even he wants to happen. If such a matchup were to happen these are two lethal killers, it would make no sense for a stalemate or a bargain too happen, one of these characters has to die, and not only would it have potential to go down as one of the greatest clashes in Marvel Television, but it could be a fantastic way to finish the last chapter of such a complete and iconic character.
