how does invincible survive conquest

Mark survives Conquest because he doesn’t beat him through raw strength alone; he survives by enduring a brutal fight, getting help from Atom Eve and others, and finally landing repeated decisive blows while Conquest is already badly weakened. In the version discussed in current fan and recap coverage, Conquest is still extremely dangerous, but his injuries, reduced condition, and Mark’s late-fight adrenaline push make the difference.

What lets Mark live?

• Viltrumites are insanely durable. Conquest can keep fighting after injuries that would kill almost anyone else, which is why the battle lasts so long.

• Conquest is weakened. Reports on the character note that he had been affected by the Scourge Virus, which damaged his healing and left him less than fully at peak condition.

• Mark gets outside help. Atom Eve helps badly enough to weaken Conquest further, which sets up Mark’s finish.

• Mark’s final burst matters. Coverage of the fight says Mark is able to win only after pushing through to a late surge and repeatedly headbutting Conquest once he’s already been softened up.

Simple version

If you want the shortest answer: Mark survives because Conquest is not at full strength, Eve helps tip the fight, and Mark manages to outlast him in a bloody, near-death brawl.

Story angle

The scene works like a classic “barely survives the monster” moment: Conquest dominates for most of the fight, Mark takes catastrophic damage, and only a final stretch of sheer persistence keeps him alive long enough to win.
