‘Invincible’ Asks: What Happens When Superheros Lose?

Editor’s Note: This article contains spoilers for the animated series “Invincible.”

As Season 4 of “Invincible” comes to close, the show leaves us on an impeccable cliffhanger, once again preparing us with questions and anticipation for the next season. This season’s finale was different from traditional superhero shows. Instead of a giant fight with the good guys miraculously winning, our heroes must suffer the consequences of their actions from this season and learn to live with them. 

“Invincible” was a long-running comic book series initially released in 2003. The comic series ended in 2018, but it received a second life in 2021 as an animated television series on Amazon Prime. “Invincible” follows the adventures of a young superhero, Mark Grayson. Mark is the son of one of the strongest superheroes on Earth, Omni-Man. Both Mark and Omni-Man possess the powers of super speed, strength, and flight due to their Alien DNA (or, in Mark’s case, half-Alien DNA, due to his having a human mother). 

So how does a series about the strongest heroes on Earth remain so interesting and capture the interest of millions of fans? If Omni-Man is the strongest hero on earth, wouldn’t he simply win every fight?  

What makes “Invincible” so interesting is the relationship between the characters. Mark, half-Alien, half-human, faces problems that cannot be solved with punches alone. 

This season is a great example of this premise. Mark, along with his father and little brother, Oliver, is tasked with saving the galaxy from his own alien species. Omni-Man comes from a planet called Viltrum, where every resident possesses the same powers as Mark–but stronger. Instead of being heroes, Viltrumites use their strength and overwhelming power to rule the galaxy with unrelenting force, forming the unstoppable Viltrum Empire. 

Teaming up with some of the greatest heroes in the Galaxy, Mark and company take the fight to Viltrum. They quickly learn the empire’s most guarded secret: there are fewer than 50 Viltrumites left. 

While on the offensive, Mark, his father, and friends end up destroying the planet of Viltrum, leaving only 37 Viltrumite survivors. Engulfed in rage after watching his home get destroyed, the Viltrum leader, Thragg, races to fight Mark and his crew. Thragg defeats them swiftly, leaving them all seriously injured. Along with the few remaining Viltrum survivors, Thragg flees through the asteroid field that was their planet minutes ago.  

Mark believes the Viltrumites are heading for his home, Earth. Terrified for the lives of his mom, girlfriend, friends, and all humans, Mark rushes home, expecting to find a ruined planet. Yet Earth is intact, with no Viltrumites in sight. 

You would think a superhero story like this would have a happier ending, but not in the case of “Invincible.” The finale concludes with no imminent danger in sight, but Mark must deal with the consequences of war and being away from home for almost a year. Dealing with the stress of letting the Viltrum get away, Mark begins to hallucinate. He has horrifying visions of his foes scattered across Earth, destroying his home and killing his loved ones.  

Mark also has to rectify his relationships; being in space for the past year, he left his girlfriend alone. During that time, she had an abortion, and Mark beats himself up for not being there for her. Mark’s estranged mother and father leave him, as well. They leave Earth to support Oliver as he recovers on an alien planet. Mark is alone. 

Mark has his girlfriend, sure, but he has no one around him who understands his trauma. So, after signing up for therapy, he goes on a flight to clear his head. On this flight, he sees Thragg again. Thinking it’s another hallucination, he charges to face his fears. Yet when his fist collides with an immovable object, Mark realizes his fears have come to life.  

Thragg calls for a truce. As the leader of a fractured people, he explains to Mark that the Viltrumites are hiding on Earth. They will not fight and they will not kill. They will simply live and rebuild their species on Earth, their new home. Mark is furious and doesn’t want to agree, but if he refuses, he knows the 37 Viltrumites can destroy Earth and every human being living on it. Reluctantly, Mark agrees. 

This is where the beauty in “Invincible” lies: Mark Grayson can’t win every fight, but he must continue on and deal with the consequences of conflict. Time and time again, we’ve seen the cause and effect of his actions. Even if Mark won a fight, he would still somehow lose the war.  

Mark couldn’t kill all the Viltrumites, and, after destroying their planet, he must bear the weight of them living on his planet. Nothing about Season Five has been released yet, but those of us who have read the comics know that Mark’s trauma and struggles are nowhere close to over.
