Some of these characters have been around for ages, while others are just getting started. Let’s dive in and see who makes the cut, starting with a surprising contender who’s more than meets the eye.
Editor’s Note: This post has been updated on March 25, 2025, to include the most recent releases and adaptations in the Invincible series.
15. Dinosaurus
Dinosaurus isn’t your typical powerhouse in ‘Invincible’. He’s a mutant dinosaur with a human-like mind, created from a lab accident gone wrong. This guy’s got massive claws, a tough hide, and a brain that’s always cooking up big plans—usually dangerous ones. He teams up with Mark Grayson for a bit, aiming to ‘fix’ the world by wiping out huge chunks of it. His strength is real, but it’s his wild ideas that make him stand out, like when he tries to flood cities to reset humanity.
What keeps him in the mix is his blend of brute force and twisted logic. He’s not just a monster smashing things—he’s got a goal, even if it’s nuts. That combo makes him a threat, especially when he’s tossing buildings around or biting through tough foes. He’s a chaotic wildcard, and while he’s not topping the charts, his raw power and big brain earn him a spot among the heavyweights.
14. Space Racer
Space Racer zooms into the ‘Invincible’ lineup with a cool vibe and a killer weapon. He’s a lone wanderer from the Coalition of Planets, riding a sleek hoverbike and wielding the Infinity Ray—a gun that can blast through anything, even Viltrumites. We first hear about him through Nolan Grayson’s books, which turn out to be true stories. His tech gives him an edge, letting him take on foes way out of his league.
His strength lies in that gun and his knack for staying calm under pressure. He’s not the toughest guy in a fistfight, but point that Infinity Ray at someone, and it’s game over. He’s a sharpshooter who doesn’t need to flex muscles to make an impact. That unique firepower puts him ahead of some brawlers, proving you don’t always need fists to be a force.
13. Levy
Angstrom Levy steps up as a human with a freaky twist in ‘Invincible’. He’s a scientist who cracks open portals to other dimensions, thanks to a machine he builds with the Mauler Twins. After a nasty accident, his body gets warped, but he comes back stronger and smarter, loaded with knowledge from alternate versions of himself. He’s obsessed with ruining Mark Grayson’s life, popping in and out of realities to cause trouble.
His power isn’t about throwing punches—it’s all in his head and those portals. He can dodge fights by slipping away or drag enemies into nasty alternate worlds. That flexibility makes him a pain to deal with, even for the big guns. He’s not invincible in a slugfest, but his tricky moves and grudge-driven smarts keep him dangerous.
12. Rognarr
Rognarr isn’t a single character but a whole species of savage beasts in ‘Invincible’. These furry, clawed monsters come from a planet Viltrumites couldn’t tame. They’re fast, tough, and strong enough to rip through Viltrumite skin—something not many can do. We see them in action when Conquest loses an arm to one, showing just how brutal they are.
They’re pure muscle and instinct, no fancy tricks needed. A pack of them can take down even the hardest hitters, relying on speed and ferocity. They don’t plan or scheme—they just attack, and that raw, untamed energy makes them a nightmare. Against smarter or more versatile foes, they hold their own by sheer relentlessness.
11. Kregg
General Kregg is a Viltrumite loyalist with a cybernetic eye that sets him apart in ‘Invincible’. He’s a high-ranking soldier under Thragg, built like a tank with all the usual Viltrumite perks—super strength, flight, and near-invulnerability. He’s been in the thick of battles like the Viltrumite War, slugging it out with Allen the Alien and others. That bionic eye gives him a little extra kick in a fight.
He’s a solid warrior, tough as nails and always ready to follow orders. His experience and grit make him a reliable heavy hitter, even among his own kind. He doesn’t outshine the elite Viltrumites, but his steady power and combat know-how keep him in the game, especially when the stakes get high.
10. Anissa
Anissa crashes into ‘Invincible’ as a fierce Viltrumite with a dark edge. She’s got the full package—strength, speed, and a healing factor that keeps her going. Sent to Earth to push the Viltrumite agenda, she takes on Mark Grayson and shows she’s not messing around. Her brutal side comes out when she forces herself on Mark, later raising their son, Marky, showing a mix of power and twisted purpose.
She’s a force because she’s relentless and skilled, holding her own against big names like Allen and even Thragg. Her tenacity and combat chops make her a standout, even if she’s not the top dog. She’s got enough juice to tangle with the best, proving she’s more than just muscle.
9. Lord Argall
Lord Argall was the emperor of Viltrum before things went sideways in ‘Invincible’. He’s Nolan Grayson’s dad, making him a big deal in the bloodline. We don’t see him fight much since he’s long dead by the time the story kicks off, killed by Thaedus. But as a purebred Viltrumite ruler, his strength and authority were legendary, shaping the empire’s brutal ways.
His legacy carries weight—his genes flow through Omni-Man and Invincible, hinting at untapped power. He’s not around to flex, but his role as a kingpin and the chaos his death sparked show he was a titan in his day. That royal Viltrumite DNA keeps him relevant, even from the grave.
8. Thaedus
Thaedus flips the script in ‘Invincible’ as a Viltrumite who turns against his own. He’s old—really old—but still packs a punch. He founded the Coalition of Planets after killing Lord Argall, sparking a civil war. His big move was unleashing the Scourge Virus, wiping out most Viltrumites. He fights in the Viltrumite War, holding his own until Thragg takes him out.
His power isn’t just physical—it’s in his cunning and resolve. He’s not the strongest brawler, but his smarts and willingness to play dirty make him a game-changer. Taking down an empire takes guts and strength, and he’s got both, even if age slows him down a bit.
7. Atom Eve
Atom Eve brings a human spark to ‘Invincible’ with powers that defy logic. She’s engineered to manipulate matter at the molecular level, turning dirt into shields or blasting enemies with pink energy. She’s Mark Grayson’s partner and a hero in her own right, taking on Viltrumites like Conquest. Her limits hold her back, but in a pinch, she can rewrite reality itself.
Her strength is in that wild potential—she could be unstoppable if she let loose. She’s not as tough as the aliens, but her ability to reshape the battlefield keeps her in the fight. When she’s pushed, like against Conquest, she shows she’s got more than enough to hang with the big leagues.
6. Conquest
Conquest is a grizzled Viltrumite warrior in ‘Invincible’, built for war. He’s got scars, a missing arm from a Rognarr, and a mean streak a mile wide. He takes on Mark Grayson twice, nearly killing him both times with sheer power and experience. Even weakened by the Scourge Virus, he’s a terror, smashing through foes with ease.
He’s a beast because he’s been at this forever—centuries of fighting hone his edge. His raw strength and love for battle make him a wrecking ball, even among Viltrumites. He only falls when Mark outsmarts him, proving brawn alone isn’t everything, but it sure gets him far.
5. Invincible (Mark Grayson)
Mark Grayson, aka Invincible, is the heart of ‘Invincible’. Half-human, half-Viltrumite, he starts as a rookie hero but grows fast. He’s got flight, strength, and durability, plus a human adrenaline boost that kicks in clutch moments. He takes on Conquest, Thragg, and even his dad, proving he’s got grit and power to spare.
His mix of Viltrumite might and human heart makes him special. He’s not the strongest out the gate, but he keeps getting better, taking hits that’d drop others. By the end, he’s leading Viltrumites, showing he’s not just tough—he’s a force that keeps rising.
4. Omni-Man (Nolan Grayson)
Omni-Man, or Nolan Grayson, storms into ‘Invincible’ as Earth’s top hero—until he’s not. A Viltrumite sent to conquer, he’s got insane strength, speed, and centuries of battle under his belt. He wipes out the Guardians of the Globe in minutes and nearly breaks Mark in their first fight. Later, he turns against Viltrum, showing his power’s matched by a shifting soul.
He’s a juggernaut with experience most can’t touch. He’s taken down planets and stood toe-to-toe with Thragg, even if he doesn’t always win. His blend of skill and raw force keeps him near the top, a benchmark for everyone else in the game.
3. Allen the Alien
Allen the Alien starts small in ‘Invincible’ but grows into a monster. He’s a Unopan bred to fight Viltrumites, getting stronger every time he nearly dies. By the time he’s leading the Coalition, he’s shrugging off blows from Kregg and Thragg, even taking Mark to the limit. He’s fast, tough, and keeps evolving.
His power comes from that relentless growth—every beating makes him better. He’s not just muscle; he’s a symbol of resistance, built to counter the toughest foes. That adaptability and raw strength push him past most, making him a cosmic powerhouse.
2. Battle Beast
Battle Beast roars into ‘Invincible’ as a lion-maned warrior obsessed with a good fight. He’s not Viltrumite, but he’s strong enough to scar Thragg and shrug off hits from Mark and the Guardians. He frees his homeworld, then hunts the galaxy’s best, wielding massive weapons and unbreakable will. His duel with Thragg is epic, ending with his hide as a trophy.
He’s a beast because he lives for the clash—pure strength and skill with no tricks. He’s not out to rule or scheme, just to test himself against the strongest. That focus and near-invincible stamina make him a terror, falling just short of the ultimate prize.
1. Grand Regent Thragg
Grand Regent Thragg rules the roost in ‘Invincible’. He’s the top Viltrumite, trained from birth to be the best, with strength, speed, and smarts that crush everyone else. He leads the empire, kills Battle Beast, and takes on Mark and Nolan in the sun itself. His reign ends in flames, but not before proving he’s unmatched.
He’s the king because he’s got it all—raw power, battle savvy, and a will to dominate. He wipes out foes with a punch, wears Battle Beast’s skin like a badge, and only falls when the odds stack sky-high. Thragg’s the gold standard, the toughest ‘Invincible’ has to offer.
