10 Strongest ‘Invincible’ Characters in the Comics, Ranked by Power
Spoiler Alert: This list includes spoilers for the ‘Invincible’ series and comics.While some absolute powerhouses have been depicted in the Invincible series on Prime Video thus far, fans have yet to experience the absolute strength shown off by both new and already introduced characters in the comic books. Even with multiple seasons now released, the animated series is still adapting only part of the original comic storyline, meaning many of the biggest power shifts, characters, and battles from Invincible‘s later arcs have yet to fully reshape the show’s on-screen hierarchy.
While there are still super-strong characters that have yet to make their way to the series, characters like Mark Grayson (Steven Yeun) himself and even Battle Beast (Michael Dorn) have yet to show off their true strength or go through the growth that eventually makes them more powerful. There’s a reason that Invincible is one of the best superhero shows of all time.

Angstrom Levy
First appearance: Invincible #16 (2004)
Fans of the animated show are more than familiar with Angstrom Levy (Sterling K. Brown) at this point, thanks to his growing role as a multiversal threat and his connection to the upcoming Invincible War storyline. Because of this, pretty much everyone already knows about Angstrom’s powers: the ability to travel dimensions and open dimensional portals at will.
Such an ability already makes him an overpowered villain, but he has also had his body radically transformed to be more of a physical match for Invincible. While he’s not as strong as the hero, Levy is far more powerful than the average bear. All of that, paired up with a genius-level intellect, makes him one of the worst things to happen to Mark Grayson and, therefore, one of the absolute toughest villains of the young man.

Atom Eve (Samantha Eve Wilkins)
First appearance: Invincible #2 (2003)
A few years ago, audiences of the series may not have thought Atom Eve (Gillian Jacobs) belonged on a list of the strongest Invincible characters from the comics. But due to the finale of the third season, Invincible Season 3, Episode 8, “I Thought You’d Never Shut Up,” non-comic readers finally got to witness the absurd amount of power that she holds.
At the end of the episode, after she seemingly dies, the show depicts the moment in which she overcomes her mental blocks and reforms her body. This has huge implications for her abilities, given the fact that it’s always been established that she can’t change biological matter, but with that change, she has become a borderline otherworldly force and one of the Invincible world’s best superheroes.
8
General Kregg
To be a general of the Viltrumite Empire, one has to be pretty dang strong. In the show, General Kregg (Clancy Brown) hasn’t been shown off much, and, honestly, his power isn’t shown off a ton in the comic, either. This doesn’t mean the strength isn’t there, though. His position, the way people speak about him, and the few feats he does accomplish in front of readers prove that he is a worthy opponent.
Unlike a lot of his comrades and inferiors in the Viltrumite Empire, Kregg is not as bellicose. He is quite a calm and logical general, and that actually makes him even more of a threat, because the only thing more dangerous than a bloodthirsty Viltrumite is precise and knows exactly what he’s doing three steps ahead of his opponent.
7
Anissa
First appearance: Invincible #44 (2007)
At the end of the day, Anissa (Shantel VanSanten) and Kregg are on pretty equal ground when it comes to power. Anissa gets the upper hand in power-scaling, however, mainly because audiences/readers have gotten to and will get to see way more of her accomplishments than the former’s and because she is a perfect mix of typical Viltrumite bloodthirsty nature and Kregg’s level-headed demeanor.
She effortlessly whoops the snot out of Mark on multiple occasions, one of them being adapted to the show already in the animated series’ Invincible Season 2, Episode 7, “I’m Not Going Anywhere.” There are more instances of this to come in the future, as well. She holds the merciless and battle-hungry nature of a typical Viltrumite, but knows exactly how to tactically exploit her enemy’s weaknesses.
6
Conquest
First appearance: Invincible #61 (2009)
After making quite the mark (an understatement) in the Prime Video series, Conquest (Jeffrey Dean Morgan) remains one of the most talked-about villains introduced in Season 3. He’s given Mark the worst beating of his entire life thus far, and was only defeated because Atom Eve had her big power-up. As shown at the end of Invincible Season 3, Episode 8, “I Thought You’d Never Shut Up,” Cecil (Walton Goggins) decided to keep him hostage, and, obviously, this is going to come to bite them in the rear.
Despite eventually being beaten by Omni-Man in the future, this doesn’t mean that when they eventually face off, he puts up an incredible fight. The way he absolutely and practically slaughtered Mark in their first fight shows just how much raw power he holds. He also has an immense love for, well, conquest and holds nothing back in his fights—that’s certainly a valid reason to be one of the strongest in Invincible.
5
Omni-Man (Nolan Grayson)
First appearance: Invincible #1 (2003)
The first big villain of the Invincible series was Mark Grayson’s own father, Nolan Grayson (J.K. Simmons)—or, as the Earth knows him, Omni-Man. Nolan was also the first big example of how strong the Viltrumite race is and the terrible future to come for Mark regarding his new role as the man to “prepare the Earth” for the empire.
Some may think that Nolan’s best showcase of power was at the end of the first season or, more recently, when he and Allen (Seth Rogen) teamed up and kicked the crap out of a few Viltrumites, but the best is yet to come. He also destroyed an entire planet in Season 1, but he will come to beat Conquest to death and even take on the strongest Viltrumite, Thragg.
4
Allen the Alien
First appearance: Invincible #5 (2003)
After being completely decimated by the Viltrumites in Invincible #23 and Invincible Season 2, Episode 3, “This Missive, This Machination!,” Allen was put into a comat and began a process that would eventually turn him into the ultimate weapon against the Viltrumite Empire—making him the same level or just under the level of strength the average Viltrumite sits at.
He would become absolutely vital in the Viltrumite War and did wonders in the fight for good. Allen is one of the only non-Viltrumite heroes who can truly stand up against and kill the world-conquering race. This makes him a force to be reckoned with and not to be underestimated in the slightest in the acclaimed superhero show.
3
Battle Beast (Thokk)
First appearance: Invincible #19 (2004)
Ever since his introduction in Invincible #19, Battle Beast has been a massive favorite among the Invincible fan base, and for very good reason. Action is one of the highlights of both the comic and the show, and if anyone brings the action, it’s Battle Beast. His profound strength might make him one of the most memorable characters in the franchise. So much so that he just recently got a solo comic book series launched in May 2025 titled Invincible Universe Battle Beast.
Alongside Allen, his strength makes him one of the few non-Viltrumites to be able to kill one. His beast-like form, mastery of weaponry, superhuman reflexes, physical strength, durability, healing, and his desire only for a worthy challenge make him seemingly unbeatable to most. He cares not for villainy or heroism. He simply seeks a good fight.
2
Grand Regent Thragg
First appearance: Invincible #11 (2004)
The true big bad of Invincible is none other than Grand Regent Thragg, the leader of the Viltrumites and the strongest of them all (for his time, alive, that is). Thragg earns his title as the overarching villain of the franchise through the astounding strength he possesses and the feats he accomplishes throughout the book.
The best way to describe the power Thragg holds is to imagine the grand strength a Viltrumite like Omni-Man has and multiply that by three. The only way Mark managed to beat him was by flying him into the sun itself and ripping his throat out with his teeth. He fought Battle Beast for days on end before murdering him.
1
Invincible (Mark Grayson)
First appearance: Invincible #1 (2003)
While the common joke of the series is that for a hero named Invincible, he’s quite “vincible,” Mark comes to be the strongest there is by the end of the series. There’s a bit of discussion surrounding Mark’s power-level in the fandom, but the proof is in the pudding with his power by the end of the comic run.
By the time Mark becomes the Emperor of Viltrum, he’s on the road to being the strongest character in the universe. Viltrumites grow exponentially stronger as they age, so the sheer fact that Mark, in his 20s, could beat Thragg in his prime in any way, shape, or form, is proof enough that by the time he’s Nolan’s current age, he’ll be virtually… invincible.
