Invincible vs Conquest: Who Would Win

Invincible vs Conquest is the rare versus argument where the fight actually happened, twice, and the two results point in opposite directions. That is why the debate has outlasted the comic run and still churns through forums and versus communities years later: the first meeting nearly ended Mark Grayson, and the rematch ended Conquest. Ask which one counts and you get the entire disagreement in miniature. Readers who anchor on the Advent of Conquest say the old Viltrumite was toying with a boy and could have killed him at any moment. Readers who anchor on the Viltrumite War say Mark grew into the man who choked him out with his own guts hanging loose. Both camps are reading canon correctly. They are reading different Marks.

The reason invincible vs conquest 2 pulls almost as hard as the original is that the two fights are not a redo, they are a before and after photograph of one person. Conquest does not change between them. He is a five-thousand-year-old weapon who was already at his ceiling when he touched down on Earth, and the Viltrum Empire built him that way deliberately. Mark changes completely. So the question of who is stronger is really a question about where you freeze Mark Grayson on his own curve, and the honest answer moves depending on where the pin goes. Sort the two profiles first, then the head-to-head resolves itself.

The Case for Invincible

Mark Grayson is a Viltrumite-human hybrid, and the split is not close to even: the alien genes overwhelmingly dominate, leaving him functionally indistinguishable from a full-blood. His abilities erupted at seventeen and sharpened fast enough that an untrained teenager could trade blows with hardened warriors of his father's race and then pass most of them. He flies through a balancing system seated in his inner ears rather than any external propulsion, hits with world-shaking force, and absorbs punishment that would liquefy nearly anything else standing on Earth. His speed sits in hypersonic ranges, and after Omni-Man left the planet Mark ranked as the fastest being on it. Full name Markus Sebastian Grayson, cataloged by the Global Defense Agency as Viltrumite Subject 2, and voiced on screen by Steven Yeun.

Mark Grayson's Adaptive Growth Curve

The trait that actually decides this matchup is not his ceiling, it is his slope. Mark's body adapts mid-fight to whatever style is being used against him, and structured conditioning compounds that adaptation instead of plateauing it. One documented ninety-day program run by the Global Defense Agency raised his strength by 138 percent and his speed by 65 percent. No full-blooded Viltrumite gets that curve. Conquest spent fifty centuries arriving at the place he already was; Mark rebuilt himself in the gap between two fights against the same opponent. Layer on a healing factor that reknits broken bones and lost organs, lungs that hold up in the vacuum of space, and surges of rage that briefly push his output past its normal limit, and the profile reads as a fighter who is dangerous precisely because he is unfinished.

The No-Kill Rule and What Ended It

His temperament is the wild card, and for most of his career it worked against him. Mark's refusal to kill separated him from Nolan morally and cost him repeatedly against opponents who carried no such line, and Conquest is the exact opponent that rule was designed to lose to. What flipped it was personal. After what Conquest did to Atom Eve, Mark abandoned restraint permanently and settled on a new rule: anyone who threatens the people he loves does not walk away. Strip the hesitation out of a fighter with Mark's raw numbers, tactical instinct, and knack for turning brawler's reflexes into disciplined technique, and the profile changes from promising to lethal. His eventual win over Conquest is exactly what cemented him among the strongest Viltrumites who have ever lived, with only Thragg still clearly above him.

The Case for Conquest

Conquest is what the Viltrum Empire builds when it has decided that subtlety is a waste of time. He is over five thousand years old, stands near six and a half feet, and carries the empire's designation Viltrumite Subject 4 alongside the blunter titles the ranks hung on him, Second Strongest Viltrumite and Mr. Ten Times Worse. The empire deployed him as a final sanction, the option reserved for jobs where nothing short of overwhelming brutality would do, and his assignment on Earth was simply to judge whether Invincible had done his duty and subjugated the planet. Cecil Stedman, who has catalogued every Viltrumite the Global Defense Agency ever tangled with, rated Conquest the strongest of them, powerful enough to rival Nolan Grayson. The two later proved it by fighting to a standstill. The CBR profile calling him the deadliest Viltrumite in the franchise's history lands on the same read.

Conquest's Feat List and Battle Scars

His feat list is a demolition record. He has flattened city blocks with a single flying charge and shattered Atom Eve's energy constructs, which are among the sturdier defenses anyone on Earth can put in front of him. He brings the standard Viltrumite package of flight, blistering speed, near-invulnerability, and regeneration, and he has had fifty centuries to learn exactly where to apply it. He is also visibly damaged in a way that reads as credential rather than liability. A long scar runs diagonally from his left temple across a blinded right eye down to the cheek, and a Rognarr on the Savage Planet tore his right arm off below the bicep while a virus had his healing crippled. He replaced the arm with a cybernetic limb of bronze and silver plating lit with amethyst glow and went straight back to work. Jeffrey Dean Morgan voices him, which is casting as characterization.

Cruelty as a Combat Tactic

Where he separates from every other member of his race is appetite. His kin drape their conquests in duty and ideology; Conquest simply relishes the violence and treats the empire's campaigns as an excuse to fight and dominate. He gravitates toward opponents who fight back, then stretches the fight so he can pile on pain, and he will turn innocents into instruments of terror to shatter an enemy's will. He taunted Mark while bleeding. He went after the bonds Mark, Oliver, and Eve hold rather than the fighters themselves. That is not sadism as flavor text, it is a tactic, and against a hero whose entire nervous system is wired to protect people it is the sharpest weapon in the fight. Beneath it runs a thread of loneliness, since the empire never gave him a true name, only the purpose stamped on him as a living weapon. He bows to Thragg and to nobody else.

Same species, same power set, same biology. That is what makes conquest vs invincible unusually clean to break down: there is no crossover guesswork about how one energy system handles another. Both men fly, both regenerate, both function in vacuum, both shrug off anything Earth's militaries can point at them. Everything that decides this fight lives in four gaps, and each of them moves depending on which Mark walks in.

Raw Power at the Advent of Conquest

At the Advent of Conquest, the power difference is not a gap, it is a canyon. Conquest stopped Mark's hardest punch without visible effort and spent the fight narrating how little of himself he was actually using, choking the kid to keep him from surrendering because a surrender would end the fun early. Cecil Stedman's assessment backs up the on-page result: Conquest was the strongest Viltrumite the Global Defense Agency had ever measured, in Nolan Grayson's weight class, and Nolan and Conquest later hit a standstill rather than a result. Mark at that point had never beaten a full-blooded Viltrumite alone. He was strong enough to be interesting and nowhere near strong enough to be a problem.

The Gap at the Viltrumite War

By the Viltrumite War the arithmetic has moved. Mark's growth is neither linear nor passive: his body adapts mid-fight to an opponent's style, and structured conditioning accelerates that adaptation instead of capping it. The ninety-day Global Defense Agency program that raised his strength 138 percent and his speed 65 percent was one block of training inside years of war footing. Conquest gained nothing across the same window. He was a finished product on arrival and spent the interval unconscious inside the Global Defense Agency's Block, then healing, then breaking out, then reporting his failure to Thragg. One fighter compounded. The other waited.

Speed, Durability, and Known Weaknesses

Speed favors Mark in both fights. His velocity sits in hypersonic ranges, and once Omni-Man left Earth he was the fastest thing on the planet. Conquest is quick by any sane standard and can level a city block with a single flying charge, but bulk speed applied as a battering ram is a different tool than reaction speed applied to escaping a grapple, and the grapple is exactly where invincible vs conquest round 2 gets decided. Durability is closer to a wash. Both regenerate, both keep operating through catastrophic damage, both have taken hits that would erase a Guardian of the Globe. Mark finished the rematch with his abdomen torn open and his insides visible. Conquest finished it dead.

The named weaknesses are worth listing because neither man presses them here. High-frequency sound wrecks Mark's inner-ear balance system and inflicts real agony, and the Viltrumite-derived Scourge Virus can strip his abilities entirely, which is the only clean off-switch anyone has ever found for him. Conquest carries a blinded right eye and a cybernetic right arm, souvenirs of the Rognarr that took the limb below the bicep on the Savage Planet while a virus had his healing offline. Neither fighter has the tooling or the temperament to work those openings, so the fight collapses back onto raw attrition, which is where the interesting part starts.

Experience and Five Thousand Years of Campaigning

Experience is Conquest's largest edge and it is not remotely close. He has more than five thousand years of active campaigning behind him against a hero whose powers surfaced at seventeen. He has fought every kind of opponent the empire ever pointed him at, and his read on Viltrumite fighting styles is not something anybody alive can match through study. But the empire trained him to win one specific kind of fight, the kind where he is the strongest thing in the room and can afford to enjoy himself. Every habit he has assumes he owns the clock.

That assumption is his real weakness. Conquest does not close fights, he extends them, and Game Rant's ranking of the Viltrumites puts the habit plainly, noting he could have killed Mark in the first meeting and chose to savor it instead. He seeks out opponents who fight back so he can pile on pain, and he weaponizes bystanders and loved ones to break an enemy's will instead of simply removing the enemy. Against most targets that is efficient terror. Against a Viltrumite hybrid whose body adapts mid-fight and whose rage measurably raises his output, stretching things out hands the opponent the one resource he needs most. Round one nearly proved it on its own. Conquest had Mark beaten several times over and kept going, and Atom Eve's searing blast plus a barrage of headbutts dropped him because he had declined to finish first. Screen Rant reads that first defeat the same way, saying his loss came from wanting a challenge rather than from being outmatched.

Mark's Win Condition Is the Chokehold

Mark's win condition is narrow and entirely physical. He cannot out-slug Conquest and does not need to. Viltrumites regenerate, but they still breathe, and the rematch turned on Mark getting inside and locking a chokehold rather than trading haymakers he was going to lose. Conquest tore his gut open while the hold was on, and Mark refused to release. That single image is the whole fight: Conquest playing to hurt, Mark playing to end it. Once Mark stopped observing his no-kill rule, an option existed that had never been available before, and it remains the only reliable way anyone has killed a Viltrumite of that caliber without a Scourge Virus or a Thragg standing by.

Temperament and the Rematch Result

Temperament seals it. Conquest answers to Thragg alone, and after losing on Earth he knelt before the Grand Regent, confessed the defeat, and asked to be punished as a lesson to the ranks. Thragg spared him and handed him a last shot at redemption: hunt down the empire's traitors, Nolan and his son. Conquest walked into the invincible vs conquest rematch with the same taunts, the same appetite, and the same plan against an opponent who had been rebuilt from the ground up specifically because of him. A five-thousand-year-old weapon that never updates is a solved problem eventually, and in the invincible vs conquest comics Mark is the one who solves it. Nolan, who always respected raw might wherever he found it, buried the body himself.

At their strongest published canon versions, Invincible beats Conquest. The comics already ran the experiment and the result stands, but the version question does most of the work here, so the verdict splits cleanly in two.

Two Versions of Mark and Two Different Results

Freeze Mark at the Advent of Conquest and Conquest wins, decisively and without much drama. That Mark had no answer for the power difference, no answer for the cruelty, and no willingness to use the one technique that actually works. Conquest stopped his best shot cold and beat him across the globe for sport. Atom Eve is the only reason the fight ended with a survivor, and she paid for it. Anyone arguing invincible mark vs conquest as a fair fight at that stage is arguing against the page. It was an execution that got interrupted.

Freeze Mark at the Viltrumite War and the result inverts. This is the version that matters for the verdict, because it is the strongest published Mark relevant to the matchup, and it is the version that walked away. Conquest arrived unchanged. Mark arrived after a stretch of growth that included documented conditioning gains of 138 percent strength and 65 percent speed, an adaptive physiology that had already studied Conquest's style once, and, critically, no moral brake. The fight plays out the way you would expect from the profiles. Conquest opens by controlling the exchange, because he is still stronger pound for pound and always will be. He taunts. He goes for the drawn-out version, because he does not know how to want anything else. Mark eats it. He is built to eat it, and every minute Conquest spends enjoying himself is a minute Mark's body spends learning the pattern.

The Rematch and the Conditional Verdict

Then the shape changes. Mark stops trading and closes distance, which is the one thing Conquest's whole approach does not account for, since nobody in five thousand years has needed to grapple him. Mark gets behind him, locks the chokehold, and holds. Conquest does what Conquest does: he punches through Mark's torso and tears his guts open, on the reasonable assumption that a hero with an injury like that lets go. Mark does not let go. He holds until the strongest Viltrumite the Global Defense Agency ever measured stops moving. Conquest ends up dead on a desolate world, buried by Nolan Grayson out of respect for the fighter he had been.

So the conditional verdict runs like this. Conquest beats every version of Mark up through the Earth invasion, and it is not competitive. Mark beats Conquest from the Viltrumite War onward, and it is close, ugly, and nearly fatal for him even so. If you want a single answer with no asterisk, take Invincible, because the matchup is not symmetrical: Mark gets stronger between engagements and Conquest does not, so any timeline long enough for a rematch is a timeline Mark eventually wins. That is the structural fact underneath all of it. Conquest was the empire's ceiling. Mark was still a floor.

Two Caveats Worth Keeping

Two caveats keep this honest. First, the win is not a demonstration of superior power, it is a demonstration of a superior win condition, which is how Game Rant frames the pair of fights, filing both results under a Mark who was never the stronger man on the day. Conquest was still the stronger raw fighter at the moment he died, and Mark took a wound that cost him weeks of recovery and could easily have killed him. Second, neither man is the top of this food chain. Mark's win over Conquest placed him among the strongest Viltrumites ever, and Thragg still outclassed him afterward. Conquest knew that too, which is why the only being he ever knelt to was the Grand Regent. Between these two specifically, the trajectory is the answer.
