Fantastic 4 MCU Theory: How Reed Richards Accidentally Unleashes Galactus & the Multiverse

Table of Contents

Hey guys! 24 hour before F4, So, we’re just days away from The Fantastic 4: First Step, the MCU’s take on Marvel’s First Family and let me tell you, this isn’t just another origin story. If the leaks and theories are right, Reed Richards might be the one who breaks the MCU. Yeah, you heard me. Our genius leader could accidentally unleash Galactus and crack open the multiverse even worse than the Avengers did.

How? Well, grab your unstable molecules, because we’re diving deep into how Reed’s arrogance could doom Earth-616, why Franklin Richards is the key to everything, and how this movie might set up Avengers: Secret Wars.

Reed’s arrogance cracks the multiverse… and Doom is waiting.

 

1. Reed Richards: Genius or Menace?

Reed Richards In the comics, his smarts can actually be a problem. He often tries to play with things he doesn't really understand completely, like in Civil War and Secret Wars. 

Now, in the MCU, we know he’s been studying the multiverse. Maybe he’s using leftover tech from Quantumania or Loki’s TVA. 

The Dimension Bridge Experiment:

• In the comics, Reed has built bridges between dimensions before (looking at you, Ultimate Fantastic Four).
• What if, in The Fantastic 4: First Step, he tries to harness energy from other universes?
• Big Mistake: The experiment works, but it also sends out a cosmic dinner bell for Galactus.

"But wait," you ask, "why would Galactus care?"

 

2. Galactus Isn’t Just Hungry

In the comics, Galactus doesn’t just eat planets at random. He senses energy signatures—and Reed’s multiversal tinkering? That’s basically a giant neon sign saying "ALL-YOU-CAN-EAT BUFFET HERE!"

How the MCU Could Play It

• The "Dimension Bridge" tears a hole in space-time, letting Galactus sense Earth-616.
• His arrival isn’t just a disaster, it’s an incursion-level event. (Remember Doctor Strange 2? Yeah, like that, but worse.)
• The Fantastic 4 aren’t just fighting to save Earth—they’re trying to close the door Reed opened.

And here’s where things get really wild…

 

3. Franklin Richards: The MCU’s Most Powerful Mutant?

If you know the comics, you know Franklin is broken.  Literally, he’s an Omega-level mutant who can rewrite reality.

Why Galactus Wants Him:

• In some storylines, Franklin creates planets. For Galactus, that’s like having an infinite food generator.
• Reed and Sue will never hand him over which means Galactus will take him by force.

Trailer & Leak Clues

• We’ve seen Susan Storm shielding something (or someone) in the teasers.
• Rumors say Franklin’s powers activate during the final battle, which could be the key to stopping Galactus… or making him stronger.

But here’s the twist…

 

4. Nullifier failure did it happen?

In the comics, the Ultimate Nullifier is the only weapon that can truly threaten Galactus. Naturally, Reed would try to build one but what if it doesn’t work? The MCU could subvert expectations by having Galactus laugh off Reed’s attempt, revealing that this version of the Nullifier is incomplete or only functional in other universes. This would force the team to resort to desperate measures. Set leaks show Ben Grimm with a sudden beard in some scenes, sparking theories that he time-travels to retrieve a working Nullifier from another reality. Imagine a Interstellar-style sequence where Ben spends years (or even decades) jumping through timelines, aging as he searches for a solution, only to return too late. This would add emotional weight to the story, showing that even the Fantastic Four’s best efforts might not be enough.

 

5.  Will Doctor Doom's secret be revealed?

The post-credit scenes could be where the real chaos begins. Rumors suggest Doctor Doom appears in the second stinger.  In the comics, Doom has always sought ultimate power, and Franklin’s reality-warping abilities would be the key to his ambitions. If Doom controls Franklin, he could reshape the multiverse in his image, leading directly into Avengers: Secret Wars. The 2015 Secret Wars comic saw Doom becoming a god, piecing together a patchwork planet called Battleworld from the remnants of destroyed universes. The MCU could be setting up a similar scenario, where Doom’s manipulation of Franklin triggers a multiversal collapse, forcing heroes from across realities to unite in a final battle. This would make The Fantastic 4: First Step not just an origin story, but the catalyst for the MCU’s next saga.

Final Verdict: Is Reed Richards the MCU’s Next Big Villain?

Think about it:

    ✅ He unleashes Galactus.

    ✅ He fails to stop him.

    ✅ His son becomes the key to multiversal annihilation.

This isn’t just a superhero movie, it’s a Greek tragedy where the hero’s greatest strength becomes his downfall.

So, what do you think?

• Is Reed Richards doomed to repeat his comic book mistakes?
• Will Franklin be the MCU’s most powerful mutant?
• And most importantly… will Galactus eat Earth-616?

Drop your theories below and get ready, because The Fantastic 4: First Step might just break the MCU in half. 🔥
