Thanos is the legendary Marvel Supervillains that fans believed yet because the guy wiped out half the universe with one snap. That alone made him a legend. But if you’ve read the comics, you know Marvel’s universe goes much, much further than what we saw in the movies. And then there are much older and scarier creatures – ones that make Thanos look almost diminutive by comparison. One of them is the god of the symbiotes known as Knull who can beat up Thanos.
The Question is: If they go down on the ground then who wins the battle? So, in Knull #3 (Ewing and Waltz, art by Juanan Ramirez), Marvel brings us this very battle and officially confirms who comes out on top.
And trust me, you’re not going to see the ending of this fight.
The Contenders: A Quick Look at Our Heavyweights
This bloody nitty gritty epic clash between Marvel Supervillains is the most awaited moment to the marvel fans because we have Thanos, the Mad Titan. He is a tactical genius, formidable strength and fully merciless. Thanos has even squared off against the Hulk, Thor, and groups of Avengers without the help of the Infinity Stones. His warped agenda animates him and doesn’t have second thoughts about stamping over whoever hopes to stop him.
On the Other side, we have Knull, the God of the Void. You may not know about him but Comic Book mentioned Knull as an ancient, dark god who created the extraterrestrial species such as Venom and Carnage are also known as Symbiotes. Why Ancient? Because he was one who dwelt in darkness before the light of the universe was.
Knull almost obliterates the Earth with the 2020 mammoth King in Black comic storyline before he is defeated at last by Eddie Brock. It is an ancient evil, pure darkness that commands a horde of dragons and monsters.
A Powerless God vs a Dominant Titan
A quick look at these two heavyweights Marvel Supervillains might lead you to think that it will become a long and hotly contested, feel-good war. But that’s not the way it turned out. In Knull series, the self-styled God of Symbiotes was never in a position of strength. He was outnumbered, and not at the peak of his power, in fact.
Who Can Win Between Marvel Supervillains?
The King in Black event shows that Knull gets the devastating defeat that makes him completely destroyed. But in comics, you can never keep a good villain down permanently. He was just recently resurrected after Venom relinquished his King in Black title. But there was a major catch — Knull was recovered in a significantly diminished state. To make matters worse, he wound up as a miserable captive of the Asgardian Goddess of Death.
Hela being the power-hungry goddess she was, desired to steal Knull’s dark powers for herself. For her grand plan, she also brought in a familiar face, her ex-boyfriend: Thanos.
To rub even more salt in Knull’s wounds, Thanos was heavily armed. He carried the Spear of Light (also called the All-Light), a mythical and potent weapon that was once wielded by Knull’s cosmic antithesis. So, the stage was set for a nearly powerless Knull, cut off from his normal source of power shadows to square off against an all-powerful Thanos wielding a weapon created of pure light. From just reading the name, Thanos was supposed to win this fight easily.
The Brutal Showdown: Knull Pulls Off the Unthinkable
As the Marvel Supervillains battle began, it appeared exactly as it should have. The Mad Titan was the clear favorite. Thanos wielded the cruel physical force and blinding might of the Spear of Light to drive the debilitated Symbiote God back. But Knull isn’t just powerful, he is ancient, intelligent and absolutely terrifying.
Since Thanos bright weapon was illuminating the battle field, Knull couldn’t use his shadowy and dark related weapons. But Knull soon learned that there was at least one place the light couldn’t reach: the darkness within Thanos.
In a cruel, horrifying turn of events, Knull weaponized the dark essence of Thanos’ own body against him. Knull suddenly explodes from Thanos, unexpectedly. The scene is so graphic and brutal. It finishes with the almighty, unbeaten Thanos collapsing to the ground with his organs in his hands, as the most devastating defeat physically, and emotionally, he has ever known.
Did Marvel Just Use the Viral Ant-Man Theory?
If that entire “Knull annihilates Thanos from the inside” thing sounds strangely familiar to you, that’s because it is. Just before Avengers: Endgame came out in 2019, a gross fan theory went viral on the internet.
Fans also joked that the simplest way to stop Thanos would be to have Scott Lang (Ant-Man) to shrink down, get inside him and then expand out again — taking out the Mad Titan from within. It was silly, over the top, and for some reason became one of the most talked about jokes in the fandom back then.
While Knull’s dark magic technique from the comic is not quite the same (and oh so much less bizarre), the heart of it definitely remains. He got inside Thanos and destroyed him from the inside out. You can’t help but wonder if the creative minds at Marvel borrowed a little bit from that iconic Internet meme to give Thanos his most brutal defeat yet. It’s the sort of brutal finisher you’d expect from the God of the Void.
The Aftermath: A New King Rises to Power
What makes Marvel Supervillains victory all the more impressive is that Knull was at his absolute weakest. He didn’t just defeat Thanos in a fistfight, he humiliated him and destroyed then left with the Spear of Light.
And then he also took full control of Thanos’ brutal Outrider army. It’s quite clear now that the God of the Void has no more games to play. In short, he is taking the weapons and armies of his enemies to become again the most powerful thing ever, and the rest of the Marvel Universe really should be shaking in their boots about what he does next.

Will We Ever See Marvel Supervillains Epic Clash in the Movies?
Now that it is established that Knull is stronger than Thanos in comics, the question is: Will this legendary rivalry ever make it to the big screen?
To be blunt, it’s somewhat confusing right now. Thanos has a significant edge in this department when it comes to the movies. After years of development through MCU storytelling, he’s become a household name.
Knull isn’t exactly new to everyone, as he made his debut in Sony’s 2024 movie Venom: The Last Dance. While Andy Serkis portrayed the character, we let a quick look at him captive on Klyntar, the symbiote homeworld. Fans were clearly left wanting more, but it was a fun little nod to the comics.
Given all the noise about reboots and major changes coming to Sony’s Spider-Man universe, where that leaves Knull on the big screen is anyone’s guess. Drag if that is all for his live-action story before it really started. The King in Black has all the ingredients needed to be a frightening, universe-ending villain in the movies, just as dynamic and evil as Thanos himself.
Conclusion
Comic Book readers can rejoice for the ultimate Marvel Supervillains Knull has joined the MCU finally. In a cosmic villain throwdown, Knull the Symbiote God reigns supreme, crushing a fallen Mad Titan in a pool of blood. As the new Knull comic series progresses, there is no telling what the God of the Void will do next with his newly stolen powers.
