Everyone has a favorite. Maybe you like the bright green glow of the Time Stone because it lets you fix your worst mistakes, or perhaps the Space Stone appeals to you because, honestly, who wouldn't want to skip the morning commute and just teleport to work? But when we start talking about the most powerful infinity stone, the conversation gets messy. It’s not just about which one looks the coolest in a gold glove.
It’s about the fundamental physics of the Marvel Cinematic Universe and the original comic lore.
Most fans immediately point to the Power Stone. It’s literally in the name, right? It blew up a planet in Guardians of the Galaxy. It’s purple, it’s angry, and it hurts just to touch it. But power isn't just about raw output. It's about control. If you can punch a moon out of orbit but your opponent can turn your fist into bubbles, who is actually winning that fight? This is the paradox of the Infinity Stones. Each one is a "singularly" that controls a pillar of existence.
Why the Soul Stone Is Quietly Terrifying
The Soul Stone is the weird one. In Infinity War, we saw that it required a sacrifice—a soul for a soul. Red Skull called it "the most unstable" of the bunch. While the other stones are basically batteries for different laws of physics, the Soul Stone has a sort of sentience.
Think about that. It’s alive.
In the comics, specifically during the Infinity Gauntlet run by Jim Starlin, the Soul Stone houses an entire dimension called Soul World. It doesn't just blast things; it judges them. It can manipulate the very essence of what makes a person them. If you’re looking for the most powerful infinity stone in terms of spiritual dominance, this is it. It is the only stone that demands something from the user before it gives anything back. It has a high "buy-in" price because its ceiling is virtually limitless.
People forget that Thanos used it to track down the "real" Doctor Strange among hundreds of duplicates. It sees through lies. It sees the truth of the universe. That’s a level of power that the Power Stone simply can't touch.
Reality vs. Time: The Battle for Second Place
Reality is whatever I want. That’s what Thanos told us on Knowhere. The Reality Stone (or the Aether) is arguably the most versatile tool in the kit. Malekith wanted to use it to plunge the entire multiverse back into eternal darkness. That’s a big goal. It defies the laws of physics entirely.
But it has a weakness.

Unless it’s backed up by the other stones, the changes it makes are often temporary. In the movies, once Thanos left the area, the "bubbles" turned back into Drax and Mantis. It’s like a temporary overlay on the world. This brings us to the Time Stone.
The Time Stone is the ultimate "undo" button. It’s what allowed Strange to look through 14,000,605 versions of the future. It allows the user to trap a literal god like Dormammu in a loop until he gives up. Is that power? Yes. But the Time Stone is also a prisoner to its own rules. You have to know how to use it, or you end up accidentally aging yourself into dust or getting stuck in a paradox.
The Case for the Mind Stone as the Most Powerful Infinity Stone
This is where things get controversial. Most people rank the Mind Stone low. They think of Vision or Loki’s scepter. They see it as a "brainwashing" tool. But they’re wrong.
The Mind Stone is the engine.
In the MCU, the Mind Stone is what gave Scarlet Witch her powers. Think about the scale of what Wanda Maximoff can do. She can rewrite reality on a town-wide scale without even having the Reality Stone. If the Mind Stone is the source of that kind of chaos magic, its potential is staggering.
Furthermore, the Mind Stone is the lens through which all other stones are filtered. To use the Space Stone, you have to think about where you want to go. To use the Time Stone, you have to process the timelines. Without the Mind Stone, the other five are just mindless forces of nature. The Mind Stone provides the consciousness required to wield the others. In many ways, it’s the "operating system" for the entire Gauntlet.
The Power Stone: Not Just a Big Battery
We have to give the Power Stone its due. It’s the "muscle." Without it, the other stones can't reach their full potential. It acts as a force multiplier. If you have the Space Stone, you can go anywhere. If you have the Space Stone and the Power Stone, you can be everywhere at once.
It’s the simplest stone, but in a straight-up fight, it’s the most devastating. When Thanos was losing to Captain Marvel, he didn't use the Soul Stone or the Reality Stone. He pulled the Power Stone out of the socket and punched her with the raw energy of the beginning of the universe. Sometimes, being the most powerful infinity stone just means being the one that can hit the hardest.
But even then, it’s a blunt instrument.
The Verdict: Ranking by Utility and Scale
If we are being honest, "power" is subjective. If you’re a scientist, the Space Stone is the most powerful because it breaks the speed of light. If you’re a philosopher, it’s the Soul Stone. But if we look at the internal logic of Marvel lore, the hierarchy usually settles like this:
- The Mind Stone: Because it governs the intent and the manifestation of the user’s will.
- The Reality Stone: Because it can literally rewrite the rules of the game.
- The Time Stone: Because causality is the ultimate cage.
- The Power Stone: Because it fuels the others.
- The Space Stone: Because distance is a major limitation in a multiverse.
- The Soul Stone: Because while it is profound, its application is often the most niche.
Actually, scratch that. Let's look at the "Snap." The Snap required all six. Why? Because you can’t kill half the universe without the Power to do it, the Space to reach them, the Soul to identify life, the Reality to make them turn to ash, the Time to do it simultaneously, and the Mind to process the massive calculation of "half of all living things."
What Most People Get Wrong About the Gauntlet
There’s a common misconception that the stones make you invincible. They don't. They make you a target.
Using the stones takes a physical toll. We saw what it did to Thanos. We saw what it did to Hulk and Tony Stark. The most powerful infinity stone is also the most dangerous to the person holding it. This is a crucial distinction that often gets lost in "who would win" debates. Power in the Marvel Universe is always balanced by a cost.
If you had to pick just one to hold in your hand right now, which would it be?
If you pick the Power Stone, you’ll likely explode. If you pick the Soul Stone, you have to kill someone you love. If you pick the Mind Stone, you might lose your own identity.
Actionable Takeaways for True Fans
If you're looking to dive deeper into the lore of the stones, here is how you should actually consume the media to understand their power levels:
- Read the 1991 Infinity Gauntlet Miniseries: This is where the stones (then called Soul Gems) are at their most cosmic. The power levels here make the MCU look like a playground.
- Watch the "What If...?" Series on Disney+: Specifically the episodes involving Infinity Ultron. It shows what happens when the stones are used with the cold, calculating efficiency of a machine. It’s the best display of the stones' raw potential ever put to film.
- Study the "Incursions" in the Comics: The stones have a limit. They only work in their home universe. If you take the most powerful infinity stone from Earth-616 to another reality, it’s just a pretty rock. Understanding this limitation is key to understanding the scale of the Marvel Multiverse.
The debate will never truly end. Fans will always argue that Time beats Power, or that Reality beats everything. But the beauty of the Infinity Stones is that they aren't just weapons. They are the building blocks of existence. They represent the different ways we experience the world—through our minds, through time, and through the very souls we carry.
When you look at it that way, the most powerful stone is whichever one governs the thing you value most.
