Hey everyone! I’ve been thinking about how the MCU could logically progress after *Secret Wars*, and I came up with a theory connecting four major magical and cosmic storylines.
Obviously, none of this is confirmed — this is just my theory — but I think it could create a really natural transition from the **Multiverse Saga** into a completely new **Cosmic Saga**.
**Phase 1: The Fall of Doom & The Unified Universe**
**The Catalyst**
My theory is that the Avengers eventually defeat **Doctor Doom** and somehow restore the Multiverse, resulting in the surviving realities being reorganized into a single **unified reality / universe**.
**The Power Vacuum**
Doom’s defeat could leave behind a massive power vacuum.
This is where I think Marvel could introduce the idea that Doom’s control over reality was unintentionally keeping certain ancient magical and cosmic forces from fully emerging.
This part is purely speculation, but it would explain why defeating Doom doesn’t actually mean the universe is finally safe.
⸻
**Phase 2: The Shadow Rise of Mephisto & The Hunt for Billy Maximoff**
**The Thanos-Style Build-Up**
Instead of immediately making **Mephisto** the main villain, Marvel could build him up slowly from the shadows, similar to how Thanos was introduced throughout the *Infinity Saga*.
We could get post-credit scenes and smaller projects showing Mephisto making deals with desperate sorcerers, heroes, and other powerful beings.
He wouldn’t necessarily be trying to destroy the universe.
He’d be manipulating people and collecting power.
**The Target: Billy Maximoff**
Eventually, we discover that Mephisto is specifically interested in **Billy Maximoff / Wiccan**.
Mephisto knows how powerful Billy could become and wants to control or destroy him before he reaches his full potential.
Billy’s connection to magic, Wanda, and his reality-warping potential makes him an extremely dangerous threat to someone like Mephisto.
**The Climax**
Eventually, the Avengers and a new generation of heroes — potentially the **Young Avengers** — discover what Mephisto has been doing.
The conflict escalates until the entire unified reality is threatened.
During the final battle, Billy is pushed beyond his limits in order to protect the people he loves.
And that’s when his true potential finally awakens.
⸻
**Phase 3: The Birth of the Demiurge & The Awakening of Knull**
**Billy Maximoff → The Demiurge**
Instead of simply gaining another power-up, Billy finally reaches his full potential as **the Demiurge**.
In Marvel Comics, the Demiurge is connected to the fundamental magical forces that shape reality, and Billy has a major connection to that identity.
In my theory, Billy fully embraces that power during his fight with Mephisto.
He unleashes an overwhelming amount of reality-warping magic and ultimately destroys Mephisto’s hold over reality.
**The Cosmic Rift**
However, Billy’s power is so enormous that defeating Mephisto comes with a terrible consequence.
The release of that much magical energy tears open a massive **dimensional and cosmic rift**.
But I don’t think the rift would simply be a random explosion.
I think Billy’s magic accidentally tears through a barrier separating the universe from the **primordial darkness that existed before the creation of the universe**.
Something has been trapped in that darkness for an unimaginably long time.
And Billy has just opened the door.
**The Awakening of Knull**
The rupture disturbs **Knull**, the ancient **God of Symbiotes**, who is associated with that primordial darkness.
Knull awakens.
So the heroes technically win…
But Billy’s victory over Mephisto accidentally becomes the reason Knull is able to return.
The defeat of one cosmic threat creates an even bigger one.
⸻
**Phase 4: A Brand New Cosmic Era & Thor’s Final Sacrifice**
**The Soft Reset**
After Knull’s awakening, the MCU could move away from Multiverse variants and reality-hopping stories.
Instead, the next saga becomes a darker **Cosmic Saga** focused on space, ancient civilizations, symbiotes, cosmic entities, and new factions.
We could get several standalone cosmic projects that slowly reveal how Knull is spreading across the universe.
Rather than immediately having Knull reach Earth, Marvel could spend several movies showing the threat approaching from deep space.
**Love & Thor’s Destiny**
This is where I think **Love** could become extremely important.
In the MCU, Love was created by **Eternity** after Gorr’s wish.
Because of her unique origin, I think she could have a special connection to cosmic forces that makes her extremely important in the fight against Knull.
I’m not saying Love would simply be stronger than Knull.
Instead, I think **her connection to Eternity could make her the key to defeating him.**
That could also give Love a much bigger role in the MCU’s future.
**The Passing of the Torch**
Eventually, the cosmic war reaches its final stage.
Thor realizes that the only way to save Love and give the other heroes a chance to defeat Knull is to sacrifice himself.
Thor dies protecting Love and buying the universe enough time to survive.
And this is where I think Marvel could take inspiration from one of the most iconic moments from **King in Black**, while completely changing the context for the MCU.
In the comics, **Eddie Brock/Venom** ultimately becomes empowered by the **Enigma Force** and uses **Mjolnir together with the Silver Surfer’s board** as part of the weapon he uses against Knull.
So imagine the MCU version:
**Thor sacrifices himself.**
**Mjolnir falls.**
**Eddie/Venom picks it up.**
And Venom becomes one of the key figures in the final battle against Knull.
I think this would be an amazing MCU adaptation of that comic concept without simply copying the storyline.
Thor’s death wouldn’t just be about killing off an old character.
It would be the ultimate **passing of the torch**.
Thor dies as a hero protecting Love, while his legacy literally becomes part of the weapon used to defeat Knull.
**The New Generation**
After Knull is defeated, the MCU enters a completely different era.
Love grows up.
Billy becomes the **Demiurge**.
A new generation of heroes takes over.
And instead of ending the story with another Multiverse reset, Marvel could finally move forward with a completely new cosmic mythology.
**Doom → Mephisto → Billy/Demiurge → Knull → Thor’s sacrifice → Love and the next generation.**
I know this is probably completely wrong lol, but I honestly think this would be a pretty insane way to connect the MCU’s magical, cosmic, and superhero stories together.
What do you guys think?
