Should Professor X the Real Villain of the Multiverse Saga?

What if Marvel’s endgame isn’t Doom. What if it’s Charles Xavier losing his damn mind?

Everyone’s out here watching Kang variants fall like bowling pins and placing bets on when Doctor Doom will finally show up and clean house. But what if Marvel is playing a way longer game? What if the next Thanos-level threat isn’t a dictator in green armor… but a bald man in a hoverchair?

Let’s talk about Professor X, Onslaught, and how Franklin Richards might be Marvel’s emergency eject button for a full-on MCU reboot. Yeah. We’re going there.

The Multiverse Is Built on Broken Heroes

Marvel’s Multiverse Saga has a pattern: the bigger the power, the bigger the fall.

Wanda went from grieving mom to full-blown horror villain in Multiverse of Madness.
Doctor Strange? Every variant we’ve met is shady at best, genocidal at worst.
Loki was once Marvel’s most charming villain—now he’s a cosmic therapist with PTSD.
Even Spider-Man: No Way Home ends with Peter choosing isolation over connection.

The entire arc is drenched in the theme of heroes breaking bad when the stakes get too personal. So ask yourself: Who in Marvel lore is the ultimate well-intentioned extremist? The one who believes he knows best for everyone?

Answer: Charles Xavier.

Multiverse of Madness Already Gave Us a Warning

Let’s not forget: Multiverse of Madness introduced a version of Xavier that’s a perfect candidate to be lured into becoming Onslaught. That Illuminati thought they had everything under control… until Wanda made them into Avenger stew.

And it’s not a one-off. The idea of Professor X crossing the line has deep roots.

In the comics, he’s erased memories, faked deaths, and manipulated kids.
He literally imprisoned a sentient mutant (Danger) just to keep his school running.
And let’s not forget the creation of Onslaught—Xavier’s worst thoughts made flesh.

This guy has always had an internal red flag just waiting to be waved.

The Onslaught Connection Is Sitting in Plain Sight

For the uninitiated: Onslaught is what happens when Xavier’s repressed dark thoughts fuse with Magneto’s rage.

The result? A psychic god so powerful he nearly destroyed every hero in Marvel Comics.

And what was Marvel’s solution?

Franklin Richards (son of Reed and Sue Storm) created a pocket universe to preserve the heroes.
That gave Marvel a chance to reboot the Avengers and Fantastic Four with fresh creative teams and character updates.
When it was time, the characters merged back in—same names, new actors, clean continuity.

You see where I’m going with this?

Why This Theory Works for Marvel’s Current Mess

Let’s be real. The Multiverse Saga hasn’t been the smoothest ride. Kang’s situation is unstable. Audiences are asking, “Where is this all going?”

A Professor X heel turn answers that question with fire:

It delivers a villain we already know and trust.
It taps into themes Marvel is already exploring: control, identity, grief, ego.
It introduces Onslaught as a real threat—one that doesn’t just fight heroes, but exposes their deepest flaws.
It sets up Franklin Richards as the ultimate reset button.

Imagine this: the saga ends with Onslaught erasing most of the timeline. Franklin recreates it—with new versions of our classic heroes.

Boom. The MCU is reborn. Same legacy. New cast.

Doom Can Wait—Xavier Is Already Here

Don’t get me wrong. I want Doom too. But rushing him into Kang’s place would waste a perfect long-game villain.

Professor X, on the other hand? He’s already on the board.

We’ve seen his arrogance, his powers, and a version of his fall. And with X-Men ‘97 reminding everyone how shady Charles can be… Marvel has a perfect setup.

Plus, it makes thematic sense. This saga isn’t about warlords or tyrants.

It’s about what happens when the people we trust the most stop trusting themselves.

Final Thought: Watch the Chair

If Marvel drops a younger Professor X soon, played with a little too much confidence, a little too much control over everyone’s thoughts, start getting nervous.

And if he starts talking about protecting minds at all costs, just know: Onslaught is coming.

And this time, the threat might not be from another universe… it might be from inside the one we already have.
