Let’s cut to the chase—Robert Downey Jr. as Doctor Doom? A game-changer. We mean, who would’ve guessed that the guy who played the invincible Tony Stark would also don the mask of one of Marvel’s most iconic villains, Victor Von Doom?
Recently, a fan-made video took the internet by storm, showing RDJ’s Doctor Doom taking down none other than Thanos, and honestly, if the Russo Brothers haven’t watched it yet, they might want to hit play before the madness that is Avengers 5 begins. The idea of Doom standing toe-to-toe with the Mad Titan has been swirling for a while, but this video throws a whole new spin on it, and it’s something the Russo brothers should seriously take note of.

In short, the Iron Man star is about to redefine what it means to be a villain. And as we’ve seen in a fan-made video making the rounds, Doom’s first showdown with Thanos? A spectacle!
Fan-made video: RDJ’s Complex Villain vs. Thanos— A glimpse into the future of MCU
Doctor Doom, often portrayed as a power-hungry tyrant with an inferiority complex, is one of the most complex villains in Marvel history. Fans are eager to see how Robert Downey Jr. will shape this character. The Russo Brothers have already teased that Doctor Doom won’t be your average villain.
This Doom isn’t just about wreaking havoc; he’s got layers, layers of intelligence, ambition, and sorcery. Doom isn’t driven by a desire to destroy; he’s driven by a need for control. But how will that play out?
The fan-made video that recently circulated gives us an interesting sneak peek into what could be. The dialogue between Doctor Doom and Thanos in this fan edit is nothing short of fascinating.

Doom essentially says:
You have brought down the wall, pierced the shield I so carefully and costly built. For what? You wish to be Baron of the Taste? Very well, I will permit you to keep the horde, if you can find your faith. Call it an endowment of goodwill, if not.
Thanos replies:
You offer me a gift? You forget I was a God as well. The Infinity Gauntlet gave me that power, and when I was a god, I did not use those powers as a mortal, as you have, saving what you can. No, I wielded them as a god should—in judgment of all living things. You are a weak god, a pretender. It is you who should bow before me.
Doctor Doom asks:
And do you have an Infinity Gauntlet now?
Thanos states:
I do not, yet I remain Thanos, the great tyrant, and for you, that will be enough.
Then Doctor Doom delivers a powerful punch to Thanos, who is seemingly injured. The former declares,
There are no gods. There is only Doom.
Wow, we mean, who wouldn’t want to see RDJ deliver such a smackdown?
Why RDJ’s Doctor Doom could surpass Thanos?

When it comes to raw power, Thanos is no slouch. He was formidable even before he laid his hands on the Infinity Gauntlet. Born on Titan, he was a force to be reckoned with, obliterating the Hulk with nothing but his fists. In comparison, Doctor Doom doesn’t need brute strength because he has something much more dangerous: intellect and sorcery.
While Thanos’ power was amplified with the Infinity Gauntlet, Doctor Doom’s might comes from his scientific genius and mastery over magic. His knowledge of both science and the mystical arts gives him an edge that many underestimate.
In the comics, Doctor Doom didn’t just beat Thanos—he utterly destroyed him. In 2015’s Secret Wars, the former gains the power of a god. Doom rips Thanos apart, pulling his skull and spine from his body with little effort. That’s right—Doom, as God Emperor, shows Thanos just how out of his league he is. But it’s worth noting that despite not having the infinity stones, Thanos is pretty powerful by himself. But he couldn’t hold a candle against God Emperor Doom.
Imagine the MCU version of that. As the Multiverse Saga continues to unfold, there’s a very real possibility that Robert Downey Jr.’s Doctor Doom could become the ultimate villain, surpassing Thanos in both power and presence. As the Russo Brothers have hinted, Doom’s role in the MCU is going to be more complex than a typical villain’s quest for destruction.

Avengers: Doomsday is already shaping up to be one of the most anticipated films in the MCU. And while we’ve only scratched the surface of what Downey Jr.’s Doctor Doom will bring to the table, it’s clear that this isn’t going to be another ‘bad guy’ story. What did we see in the fan-made video? A little taste of that.
If the Russo Brothers take any lesson from this, it’s that Doctor Doom has the potential to be the next big bad, but not in the traditional sense. Let’s hope that RDJ brings this complex, multi-layered villain to life the way only he can. As the saying goes, “The darkest nights produce the brightest stars”—and Doctor Doom might just be the star we need in the MCU’s upcoming battles.
Avengers: Doomsday will hit the theaters on May 1, 2026.
