Warning: This article contains SPOILERS for Invincible season 3.Invincible's most powerful characters after season 3.

Naturally, there are some exceptions, as Atom Eve's new regeneration powers make her more competent than ever before, while Allen and Battle Beast have proven they can go toe-to-toe with Viltrumites. However, the alien species still set the standard when it comes to Invincible's power scale, making it interesting to see where each Viltrumite ranks against the other. While every Viltrumite introduced so far has proven far stronger than Earth's typical heroes and villains, some excel way beyond their peers, whereas others lag behind, creating questions about who really is the most powerful as of season 3's finale.

9 Oliver Grayson

Oliver's Half-Thraxan Side Makes Him Much Weaker Than The Other Viltrumites

Despite inheriting some of his father's more ruthless traits, Oliver is still Invincible's weakest Viltrumite, and by some distance. He is still superior to most characters in the show, as he is directly responsible for the Mauler Twins' Invincible deaths and was also able to withstand some attacks from Conquest, but he simply doesn't match the speed or strength of the other Viltrumites. Oliver is still young and has the potential to further develop his powers, but his Thraxan side holds him back.

Oliver can still present a major challenge to most characters in the franchise, but out of all the Viltrumites we've met so far, his powers seem the most limited.

Like the protagonist, he is only half-Viltrumite as Oliver's mother is from Thraxa, a planet with an incredibly short lifespan. As a result, Kid Omni-Man's true power is hard to gauge, but it's clear he doesn't come close to matching his brother's strength, and it doesn't look like he will any time soon. Oliver can still present a major challenge to most characters in the franchise, but out of all the Viltrumites we've met so far, his powers seem the most limited.

8 Viltrumite Executioners

The Duo Were Put On Executioner Duty For A Reason

Being put on execution duty is by no means a small task, but compared to conquering planets, it falls pretty short in comparison. As a result, the duo responsible for Omni-Man's execution is seemingly less powerful than any of the other pure-blooded Viltrumites we've seen so far, but this doesn't make them weak. They were never given names in the show, but the executioners still made a big impression while beating up Nolan and sentencing him to death.

Their limited screen time highlighted that they were capable of hurting three of the show's strongest characters as they bloodied Omni-Man, Allen the Alien, and Battle Beast. However, Allen didn't show his full power in Invincible season 3's prison escape sequence as he let one of the executioners gain the upper hand intentionally. Additionally, one of the executioners was killed by Allen and Nolan, while the other seemingly lost his fight with Battle Beast, proving that, despite their undisputable strength, the duo falls towards the bottom of the power rankings.

7 Vidor

Omni-Man Was Able To Deal With Vidor Fairly Comfortably

Of the three Viltrumites involved in attacking Thraxa, Vidor proved to be the most vulnerable, and it's unclear if he even survived the ordeal. He arrived alongside Lucan and Thula to capture Omni-Man and cause chaos on the planet, something the trio succeeded in. However, while Vidor undoubtedly played a vital part in the successful mission, he failed to handle Nolan, with most of his offense coming while Omni-Man was worrying about his son.

The villain is certainly no joke, as he wiped out the Thraxans with ease and managed to land some blows on Omni-Man, but he was still on the losing end of the fight.

Nolan was able to deliver a punch with both fists that seemingly split part of Vidor's head and proceeded to crush him under his boot, only failing to follow through to aid Mark. Assuming Vidor survived, he certainly won't be in a rush to fight Omni-Man again soon, as he clearly isn't quite up to his adversary's strength.

6 Thula

Thula's Ruthless Aggression Proved She Is A Dangerous Opponent

Like Vidor, Thula was also a crucial part of the attack on Thraxa, but she seemed to show slightly more promise than her ally. She did have the distinct advantage of facing off against an apprehensive Mark who was yet to reach his full potential, but Thula appeared to be the one dictating the fight, unlike Vidor against Omni-Man. The blade attached to her hair helped injure Mark, and although the protagonist did briefly get the upper hand, Thula showed the killer's instinct to strike as he hesitated, stabbing Invincible through his torso.

Omni-Man did ultimately break her jaw with ease and left questions over whether she survived as well, suggesting if the roles were reversed, Vidor might look the stronger of the two. Still, based on what the series has shown so far, Thula seems a little bit craftier and more lethal than her comrade, and given she came close to killing Mark Grayson, there's no denying she is still one of the stronger Viltrumites, even if others outrank her.

5 Lucan

The Villain Was Able To Survive Severe Injuries & Still Take Down Omni-Man

After seeming like the first to be defeated on Thraxa, Lucan actually proved to be the toughest of the Viltrumite invaders as he survived what looked like certain death and still managed to severely injure Omni-Man, indicating he is among the toughest the planet has to offer. He faced off against Mark to begin with - who was trying to protect Andressa - and quickly got the better of him without breaking a sweat. Lucan then proceeded to fight Omni-Man and was swiftly defeated, suggesting he wasn't anything special.

However, to everyone's surprise, he survived Omni-Man's brutal attack and delivered a devastating kick that seemed to break Nolan's back. He was then able to call the Viltrum empire before collapsing moments later. With Invincible season 3 delaying the Viltrumite invasion storyline, the season 2 battle was the last we saw Lucan and his fellow soldiers, but the fact he still found the strength to deliver such a forceful kick after the punishment he received indicates that he is extremely formidable and could be a problem in the future.

4 Anissa

Anissa Easily Defeated Mark Back In Season 2

After her memorable introduction in season 2's penultimate episode, it seemed like Anissa would be one of Invincible season 3's main villains, yet she hasn't appeared since. Still, her fight with Mark proved just how powerful she is, as she wiped the floor with the protagonist without even trying. She was faster, stronger, and most likely more durable, even killing the villain Mark was struggling with in one blow, proving just how advanced she was compared to most other Viltrumites we've seen.

Anissa struggled to beat Allen, who managed to make her bleed before intentionally throwing the fight so that he could get captured.

Had it not been for season 3, there would be a genuine case for putting her at the top spot, but others have since sured her strength. Anissa struggled to beat Allen, who managed to make her bleed before intentionally throwing the fight so that he could get captured. Their battle indicated that Anissa isn't completely unstoppable, but based on the brief action we've seen from her, she is easily one of the deadliest antagonists currently in the show, and without seeing Kregg or Thaedus in action, there are only a handful of Viltrumites conclusively above her.

3 Mark Grayson

Invincible's Protagonist Has Grown Into One Of The Show's Strongest Characters

Despite how easily Anissa dealt with Mark, the protagonist seems stronger than ever after season 3 and deserves to be recognized as one of the most powerful Viltrumites in the Invincible universe. Not only did season 3's opening sequence imply Mark had evolved significantly, but the action throughout the season made him more dangerous than ever. His run-ins with Doc Seismic, Mister Liu, Powerplex, Angstrom Levy, and even evil variants of himself all toughened him up, but no one tested him more than Conquest.

His showdown in the finale was easily his hardest fight yet and was full of brutality, but Mark managed to survive the ordeal and take down one of Viltrum's most fearsome warriors. Even though he's only half-Viltrumite, the protagonist continues growing stronger with each battle, and Mark's vow to kill anyone who threatens his family in Invincible season 3's ending highlighted that he won't be holding back in the future, proving just how menacing he has become.

2 Omni-Man

Nolan's Fierce Reputation & Violent History Suggest He Is Still Extremely Dangerous

Although Omni-Man didn't have a lot of action throughout season 3, his history in the series has proven he is one of the most dangerous Viltrumites around. He has a pretty big reputation among his people, and his time on Earth proved just how dominant he is. Killing the original Guardians of the Globe single-handedly was a clear sign that he's not only violent and powerful but also a great strategist. In addition, the beating he inflicted on his own son proves he is not someone you want to cross, as he can be extremely cruel.

Nolan may have mellowed out a little, but he can still get his hands dirty when necessary, which his prison escape scene proved. The only fight he failed to win was when Lucan caught him by surprise, and even then that felt more like a draw given his opponent collapsed right after. It can be easy to forget just how strong Omni-Man has been throughout Invincible's three seasons, but the destruction he has caused to Earth and the opponents he has taken down speaks for itself, not to mention the fact he wiped out an entire planet on his own.

1 Conquest

Despite His Defeat, Conquest Is Still The Most Powerful Viltrumite The Show Has Introduced So Far

Conquest may have lost his only fight so far in Invincible, but he's still undoubtedly the strongest Viltrumite the series has introduced as of season 3. His battle with Mark in the finale was brutal, as the villain toyed with the hero and proved his superiority. His big attacks caused devastation around the city, and he managed to injure Mark, take Oliver out of action, and essentially kill Atom Eve before she resurrected herself and delivered a powerful blast that gave the protagonist the upper hand to eventually take down Conquest.

His defeat came mainly because he wanted a challenge, not because Mark and Eve were stronger than him. Even after Mark ruthlessly headbutted him, it looks like Conquest will be part of Invincible season 4 since Cecil seemingly kept the villain alive, suggesting his strength could be shown once again. Regardless, his single fight proved that Conquest is way beyond any Viltrumite we've seen so far, and he could have killed Mark any time he wanted, making him the deadliest character currently in Invincible.
