Conquest’s Apparent Defeat in Invincible Season 3

Mark’s Brutal Battle with Conquest
The Invincible Season 3 finale delivered one of the most gruesome and intense fights in the series, as Mark Grayson finally confronted Conquest, the ruthless Viltrumite warrior. The battle was brutal, emotional, and incredibly violent, spanning nearly 30 minutes of the episode. Mark, with assistance from Atom Eve and his younger brother Oliver, fought Conquest to the brink of death, eventually smashing his skull repeatedly until he appeared completely destroyed.

Following the fight, Mark demanded to see Conquest’s remains, hoping to confirm that his enemy was truly dead. However, the episode’s final moments revealed that Cecil Stedman had secretly preserved Conquest’s body, deceiving Mark into believing the Viltrumite was gone for good. Instead of disposing of him, Cecil imprisoned Conquest in a 400-ton steel block, with security measures in place to detonate explosives if he attempted to move.
Why Cecil Stedman Kept Conquest Alive
Cecil’s decision to capture rather than kill Conquest aligns with his larger strategy to understand and counter the Viltrumite threat. By keeping Conquest alive, Cecil hopes to extract valuable intelligence about the Viltrum Empire’s plans and potential weaknesses. However, this choice also introduces significant risks, as Conquest remains one of the most dangerous and resilient enemies Mark has ever faced.

First Battle: Mark vs. Conquest
In Invincible #62-64, Conquest engages Mark in a brutal battle that nearly kills both of them. Mark, pushed to his limits, unleashes his full Viltrumite strength, using a series of devastating headbutts to reduce Conquest’s head to a bloody pulp. Believing his enemy to be dead, Mark collapses, exhausted and severely injured.
However, just like in the animated series, Conquest’s Viltrumite healing factor allows him to survive, and he is secretly taken into captivity by Cecil. While Cecil attempts to interrogate him, Conquest eventually escapes and rejoins the Viltrumite Empire, setting up another inevitable showdown.
Final Battle: Mark vs. Conquest (For Real This Time)
After his escape, Conquest remains a key figure in Grand Regent Thragg’s forces, eventually leading to a second, final battle between him and Mark. This confrontation proves to be even more personal and intense than their first, as Conquest targets Mark’s loved ones, including his brother Oliver.
In the comics, Conquest nearly kills Oliver, sending Mark into a rage. The two engage in another grueling, blood-soaked fight, which ends when Mark strangles Conquest to death. This marks the true and definitive end of Conquest in the Invincible comic series.

Robert Kirkman Confirms Conquest’s Return
Series creator Robert Kirkman has confirmed that Conquest will return in Invincible Season 4, stating:
“I don’t think Cecil would’ve gone to all the trouble of containing Conquest the way he did if Conquest was dead. So I think it’s safe to say that Jeffrey Dean Morgan’s Conquest will return in some capacity.”
This strongly suggests that the animated series will follow the comics closely, leading to Conquest’s eventual escape and a second battle with Mark.

How Conquest’s Return Could Impact Season 4

With Invincible Season 4 already confirmed for release in early 2026, Conquest’s survival adds major stakes to the upcoming season. Possible storylines include:
- Cecil’s risky interrogation of Conquest, which could reveal new information about the Viltrumite Empire.
- Conquest’s inevitable escape, leading to another devastating showdown with Mark.
- Potential alliances or betrayals, as Conquest may attempt to manipulate his captors.
- Further exploration of Mark’s internal conflict, as he struggles with the morality of killing an enemy like Conquest.
Conquest is far from finished in the Invincible universe. While Mark believes he killed the ruthless Viltrumite, the Season 3 finale confirms that Conquest is still alive in Cecil’s custody. This mirrors the comics, where Conquest returns for a second and final battle before meeting his ultimate demise.
