Honestly, the power scaling in the Invincible universe is a total mess if you only look at the surface. You've got guys like the Immortal who look like top-tier gods, only to get ripped in half every other Tuesday. Then you have characters like Allen the Alien, who starts off as a galactic punching bag and ends up basically becoming a one-man army.
Most people assume Mark Grayson is the peak because, well, the show is named after him. But if you've actually read the Robert Kirkman comics or kept up with the insane Season 3 finale on Prime Video, you know that "Invincible" is more of a goal than a current status. Strength in this universe isn't just about who can bench press a planet; it’s about "Smart Atoms," age, and whether or not your species is designed for genocide.
Ranking the most powerful characters in Invincible requires looking past the flashy capes and into the brutal reality of Viltrumite biology and cosmic evolution.
The Absolute Peak: Grand Regent Thragg
If we’re talking raw, unfiltered power, Grand Regent Thragg is the undisputed king. Or Regent. Whatever. Basically, he’s what happens when you take a Viltrumite and spend thousands of years refining their DNA through a "might makes right" filter. Thragg isn't just strong; he's a tactical genius who has spent millennia leading an empire of literal supermen.
When Thragg finally shows up, he makes Omni-Man look like a toddler. In the comics, there’s a moment where Nolan tries to punch him, and Nolan's hand literally shatters against Thragg's face. That’s a level of durability that shouldn't even exist. He can fight for days without tiring, and it took a literal sun to finally bring him down. Even then, he was winning the fight until the very last second.

The Wild Card: Battle Beast (Thokk)
You can't talk about power without mentioning the guy who lives for the "worthy scrap." Battle Beast is terrifying because he doesn't have a grand plan or an empire to run. He just wants to find someone who can actually hurt him.
He is one of the only beings in the galaxy who can go toe-to-toe with Thragg and not immediately die. In fact, their legendary fight lasted for days. Battle Beast actually disemboweled himself just to make the fight "fair" because Thragg was injured. Talk about a weird flex. If he hadn’t done that, there is a very real chance he would have walked away as the strongest being in the universe.
The Evolution of Allen the Alien
Allen is basically the Unshoppable Saiyan of this franchise. Every time he gets beaten to a pulp and survives, he comes back significantly stronger. It’s a biological trait of the Unopans, and by the end of the series, he’s one of the few characters who can actually make a high-ranking Viltrumite bleed with a single slap.
After his "reboot" in Season 2 and 3 of the show, Allen’s durability hits a point where even someone as scary as Anissa can't really do permanent damage. He’s the ultimate counter-measure to the Viltrumites because his power doesn't have a known ceiling.
The "End of Series" Mark Grayson
Mark is a late bloomer. Because he’s half-human, his powers took a while to kick in, but that human side actually gives him a weird advantage. He heals faster and has an emotional drive that pure Viltrumites lack.
By the time we hit the 500-year time skip at the very end of the story, Mark is likely the most powerful character in existence. He’s lived through centuries of combat, his Viltrumite cells have hardened with age, and he’s learned to stop holding back. Younger Mark is a B-tier fighter compared to the heavy hitters, but Emperor Mark is a different beast entirely.
Why Atom Eve is Technically the Most Dangerous
We need to be real about Samantha Eve Wilkins. Her "mental blocks" are the only thing keeping her from being the most powerful character in Invincible. She can manipulate matter at the atomic level.

- She can turn the air into gold.
- She can rewrite someone's DNA.
- She can literally refuse to die.
As we saw in the Season 3 finale, when Eve is near death, those limiters break. She essentially becomes a god. She can rebuild her own body and even "buff" the people around her. If she ever truly mastered her powers without the psychological trauma holding her back, she could probably just turn the entire Viltrumite fleet into a bowl of petunias.
The Heavy Hitters: Conquest and Omni-Man
Nolan (Omni-Man) is the face of the series, but he’s actually mid-tier among the Viltrumite elite. He’s a Great General, sure, but characters like Conquest are on another level of brutality. Conquest is a veteran of the planet-conquering business who hasn't lost a fight in centuries.
When Mark finally beats Conquest, it's not because he's "stronger" in a gym sense. It's because Mark is willing to headbutt a guy until his own skull cracks just to win. It’s that grit that bridges the gap between Nolan’s generation and the new power level Mark eventually reaches.
Actionable Insights for Fans
If you're trying to win an argument about who would win in a fight, keep these factors in mind:
- Age Matters: Viltrumites get stronger as they get older. This is why Thragg and Conquest are so much scarier than the younger soldiers.
- The "Sun" Factor: No matter how strong a character is, the core of a star is the ultimate equalizer. Even Smart Atoms have a melting point.
- Mental Blocks: Power isn't just physical. Characters like Atom Eve and even Mark are often limited by their morality or trauma.
The ranking of the most powerful characters in Invincible is constantly shifting as the show catches up to the comics. While Thragg is the king of the mountain for now, the series proves that evolution and sheer willpower usually trump raw muscle in the end.
