All 15 Viltrumites Ranked from Weakest to Strongest

If you’ve been hooked on the wild world of ‘Invincible,’ you know the Viltrumites are the heavy hitters of this universe. These alien warriors from the planet Viltrum bring jaw-dropping strength, speed, and a knack for conquering planets to the table. With their brutal culture and near-indestructible bodies, they’ve left a mark on both the comics and the animated series that’s hard to ignore. We’re diving into the lineup of these cosmic powerhouses, sorting out who’s got the muscle and who’s still climbing the ladder.

The Viltrumites aren’t just about raw power – their stories weave through loyalty, betrayal, and some seriously epic fights. From half-human hybrids to pure-blooded veterans, each one has a unique flavor to their strength. Whether it’s a young fighter still finding their footing or a battle-hardened leader, their abilities shape the chaos of the ‘Invincible’ saga. Let’s break down the 15 named Viltrumites we’ve come to know, starting with the less seasoned and working up to the ones who could crack a planet in half.

15. Molly Murphy

Molly Murphy is one of the lesser-known Viltrumites, a hybrid born from the union of a Viltrumite and a human. She’s part of the next generation, growing up on Earth after the big shake-ups in the Viltrumite Empire. We don’t see much of her in action, since she’s still a kid during the main events of ‘Invincible.’ Her existence ties into the later comics, where Viltrumites start blending with humanity to rebuild their race.

She’s here because her Viltrumite blood hasn’t had time to shine yet. Being so young, Molly hasn’t faced the battles or training that forge the others into warriors. Her potential is there, tucked away in her DNA, but without the chance to flex it, she’s more of a promise than a proven force. Age and experience matter a lot with these aliens, and she’s just starting out.

14. Terra Grayson

Terra Grayson is the daughter of Mark Grayson and Atom Eve, carrying Viltrumite genes from her dad’s side. Born late in the ‘Invincible’ comics, she’s another young hybrid who shows up as the story leaps forward in time. Terra’s got spunk and a bit of her father’s stubborn streak, but we only catch glimpses of her as a child, not a fighter. She’s part of the new era where Viltrumites aim for peace, not conquest.

Her spot makes sense when you think about her age. Terra’s Viltrumite heritage means she could grow into something fierce, but she hasn’t had the years or the fights to prove it. Like other kids on this list, she’s got the raw material – super strength and durability are in her blood – but no track record. It’s all about what she might become, not what she’s done.

13. Markus Murphy / (Kid) Invincible

Markus Murphy, dubbed ‘Kid Invincible,’ is the son of Anissa and a human named Mark. He pops up in the comics as a hybrid Viltrumite, born after his mom settles on Earth. Markus is a scrappy little guy, showing some of that classic Viltrumite toughness even as a toddler. His brief moments hint at a future where he might take after his uncle, Mark Grayson, in the hero game.

He’s not higher up because he’s still a child during the story. His Viltrumite side gives him a head start – he’s stronger than any human kid – but he hasn’t tangled with the big threats yet. The comics tease his potential, especially with Anissa’s fierce genes, but he’s too young to have honed his skills or faced real combat. It’s a waiting game with him.

12. Lucan

Lucan is a full-blooded Viltrumite soldier we meet in the animated ‘Invincible’ series during the Thraxa battle. He’s a bulky guy, built like a tank, and jumps into the fight to hunt down Omni-Man. Lucan takes on Mark Grayson first, tossing him around with ease, before getting gutted by Nolan. Even then, he pulls off a nasty surprise kick that nearly snaps Omni-Man’s back before collapsing.

His placement comes down to how he stacks up in that one brutal brawl. Lucan’s got the strength and grit of a seasoned Viltrumite, but he doesn’t last long against Nolan’s experience. That kick shows he’s got power, but his quick defeat means he’s not in the same league as the heavyweights. He’s a solid fighter, just not one of the elite.

11. (Great) Thaedus

Thaedus is an old Viltrumite with a twist – he’s the first to turn against his own kind. He founded the Coalition of Planets to stop the Viltrumite Empire’s rampage, even assassinating their emperor, Argall, way back when. In the comics, he teams up with Mark and Nolan to smash through Viltrum itself, proving he’s still got serious muscle despite his age.

What keeps him here is his focus on brains over brawn. Thaedus is a legend for his rebellion and strategy, not just his fists. He can hold his own – flying fast enough to help destroy a planet is no joke – but he’s past his prime when Thragg decapitates him. His strength is real, but others outshine him in pure combat power.

10. Onnan

Onnan is one of Thragg’s kids, a hybrid born from a Viltrumite dad and a Thraxan mom. We see him in the comics as a violent little monster, tearing through planets with his twin sister, Ursaal. He’s got purple skin from his Thraxan side, but that Viltrumite strength lets him carve up enemies like it’s nothing – until Mark puts him down for good.

He’s in this slot because he’s young and reckless. Onnan’s got raw power and a mean streak, but he lacks the control and experience of older Viltrumites. His Thraxan half speeds up his growth, so he’s tougher than most kids, but he’s still green compared to the battle-tested adults. That’s why Mark handles him without too much trouble.

9. Ursaal

Ursaal, Onnan’s twin sister, is another of Thragg’s Viltrumite-Thraxan offspring. She starts out loyal to her dad, joining him in his exile after Viltrum falls. In the comics, she’s a fierce fighter, clashing with Mark and even holding her own against General Kregg near the end. After Thragg’s defeat, she surrenders and adapts to the new Viltrumite way.

Her position fits because she’s got potential but not the full package yet. Ursaal’s strong for her age – those Viltrumite genes don’t mess around – and she’s got some solid combat chops. But she’s still a step behind the veterans. Her late-game fight with Kregg shows she’s close to the big leagues, just not quite there.

8. Oliver Grayson / Kid Omni-Man

Oliver Grayson is Mark’s half-brother, born to Nolan and a Thraxan woman named Andressa. Known as ‘Kid Omni-Man,’ he grows up fast thanks to his mom’s short-lived species, hitting his teens while Mark’s still young. In the comics, he fights alongside Mark in the Viltrumite War, taking on Conquest before Thragg ends him.

He lands here because he’s a hybrid with a lot of heart but not the full Viltrumite edge. Oliver’s smart and heals quick, which gives him an advantage, but he’s outmatched by purebreds like Conquest. His youth and mixed blood mean he’s tough, but not on par with the grizzled warriors who’ve been at it for centuries.

7. Thula

Thula is a female Viltrumite with a wild card – she uses her long braid like a weapon. She’s been around since Thragg took over thousands of years ago, popping up in both the comics and the show. In the animated series, she nearly chokes Mark out before Nolan smashes her jaw, while in the comics, she battles Battle Beast during the Viltrumite War.

She’s got this spot because she’s a crafty fighter with staying power. Thula’s not the strongest physically, but her experience and tricky style make her dangerous. She holds her own against Mark and others, but Nolan’s quick takedown shows she’s not at the top. Her age helps, though – she’s still kicking after millennia.

6. General Kregg

General Kregg is Thragg’s right-hand man, a Viltrumite with a cybernetic eye that sets him apart. In the show, he shows up on Thraxa to order Mark to finish Nolan’s mission, while in the comics, he fights Allen the Alien and Thaedus during the Viltrumite War. He’s calm and calculating, not as bloodthirsty as some, but still a beast in a scrap.

His rank comes from his balance of power and smarts. Kregg’s strong enough to tangle with heavy hitters like Allen, and that eye probably gives him an edge we don’t fully see. He’s not as wild as the top dogs, but his high status and combat skills mean he’s a cut above most. He’s a leader who can back it up.

5. Anissa

Anissa is a fierce Viltrumite soldier who storms into ‘Invincible’ with a bang. In the comics, she comes to Earth to push Mark into joining the Empire, beating him senseless to make her point. She later softens up, starting a family, but her early fights – including tussles with Allen and Thragg – show she’s a terror in battle.

She fits here because she’s got the skills and the drive to take on almost anyone. Anissa’s fast and brutal, outpacing Mark early on and giving Allen a run for his money. She’s not the absolute strongest, but her training and ferocity put her ahead of most. Only the real monsters can overshadow her.

4. Nolan Grayson / Omni-Man

Nolan Grayson, better known as Omni-Man, is Earth’s former hero turned Viltrumite enforcer. In the show, he wipes out the Guardians of the Globe like it’s nothing, and in the comics, he takes on everyone from Mark to Thragg. He’s a purebred Viltrumite with centuries of experience, eventually leading the race after turning against his old ways.

He’s up here because he’s a powerhouse with a proven record. Nolan’s strength lets him rip through heroes and Viltrumites alike, and his shift to a good guy doesn’t dull his edge. He destroys Viltrum with help, but Thragg still gets the better of him in the end. That shows he’s elite, just not untouchable.

3. Conquest

Conquest is an old, grizzled Viltrumite who lives for the fight. In the comics, he’s sent to Earth to deal with Mark, nearly killing him in a savage beatdown. He’s got a scarred face and a missing arm from past battles, but that doesn’t slow him down – he takes on Mark and Oliver together before Eve’s powers tip the scales.

He’s this high because he’s a walking war machine. Conquest’s age and love for combat make him a nightmare – he shrugs off insane punishment and keeps coming. Mark only beats him with help, which says a lot about his raw might. He’s not the smartest, but in a straight fight, he’s almost unstoppable.

2. Mark Grayson / Invincible

Mark Grayson, our hero ‘Invincible,’ starts as a half-human rookie but grows into a legend. In the comics, he takes down Conquest, helps smash Viltrum, and eventually kills Thragg in a sun-soaked showdown. By the end, he’s emperor of a peaceful Viltrumite Empire, aged up and tougher than ever after 500 years.

He’s near the top because he keeps getting stronger and smarter. Mark’s Viltrumite half matures over time, and his human side gives him grit the others lack. He beats monsters like Conquest and Thragg through sheer will and teamwork, proving he’s more than just muscle. Only one guy edges him out in the prime of their power.

1. Thragg

Thragg is the Grand Regent of the Viltrumite Empire, bred to be the strongest of his kind. In the comics, he kills Battle Beast, Oliver, and Nolan, and nearly takes out Mark in their final clash. He rules with an iron fist, even after Viltrum’s destruction, plotting to rebuild his people on Earth until Mark ends him in the sun.

He’s the king here because nobody matches his brute force and cunning. Thragg’s trained from birth to dominate, and he does – taking down the toughest foes with ease. Mark only beats him with every trick in the book and a burning star. At his peak, Thragg’s the ultimate Viltrumite, hands down.
