[Review] Invincible Season 3 | Amazon Prime

Invincible Season 3 started streaming on Amazon Prime Video in early 2025. Unlike Season 2, it didn’t split the season into parts, instead rolling out episodes weekly.

The series stars Steven Yeun, who voices the titular character of Invincible (Mark Grayson), J K Simmons as Omni-Man (Nolan Grayson), and Sandra Oh as Debbie Grayson. The series boasts many more talented actors including Gillian Jacobs, Walton Goggins, Zachary Quinto, Jason Mantzoukas, Ross Marquand, Grey Griffin, Malese Jow, Fred Tatasciore, Ben Schwartz, and the list goes on and on.

After 2 stellar seasons, does Invincible hit a hat trick?

Invincible Season 3 Review:

I’ve come to love Invincible more and more with each new season. While Season 1 felt just above average to me, the way the makers have dumped a multiverse worth of emotional baggage and world-ending threats on Mark’s head have been incredibly rewarding to us viewers. I’m not going to diss the underwhelming art style, because honestly, it feels a bit nostalgic to me. The animation really reminds me of my childhood watching Batman and the Justice League.

I randomly stumbled upon season 3 when searching for something to watch. I was upset that I hadn’t been aware of the release, and since that point, I eagerly waited for Thursdays so I could watch the next episode. But, what did I think of Invincible Season 3?

The compelling complexity of Mark’s situation

Season 2 ended one quite a punch in the gut. Mark was back on earth along with his younger half-brother, Oliver. Angstrom Levy’s attack left him in quite a dilemma, forcing him to kill the dimension-hopping mad scientist. Season 3 picks off a few months later, when Mark (Steven Yeun) is training under Cecil’s supervision (voiced by Walton Goggins). As threats begin to emerge, Mark/Invincible is made aware of Cecil’s darker secrets—SPOILER ALERT: Cecil has cloned and rehabilitated dead superheroes, and villains! And that’s just episode 1!

As the season progresses, Mark’s world continues to grow rockier as he breaks away from the GDA (Global Defence Agency), and becomes a freelance superhero. All this, while keeping his family safe, and training Oliver to become a good-hearted superhero himself. Not an episode goes by before a world-ending threat, a family-threatening crisis, or a soul-crushing moral dilemma disrupts Mark’s attempt at returning to normalcy. The very fact that the makers are ready to indulge in difficult questions, enforcing relentless trials and tribulations upon these characters is a testament to the fact that good writing is still alive.

Mark’s situation continues to grow complex, reaching its epitome with the Invincible War. And that’s just the penultimate episode. Seriously, Invincible has packed more punches and philosophical dilemmas in eight episodes of roughly 45 minutes each, than the Marvel Cinematic Universe has in all of its content post Endgame.

People, not Characters

Mark isn’t the only one facing dilemmas and punishments. While the brutality of Invincible’s world is very much apparent, what makes it a tough pill to swallow are its inhabitants. They’re not just mere characters, but real people with real emotions and real dreams waiting to be shattered.

Be it Debbie’s (Sandra Oh) attempt to get back into dating after Nolan called her his pet, or even Shrinking Rae (Grey Griffin) quitting her superhero life, to Rexplode (Jason Mantzoukas) growing up and starting a romance with Rae, every single character arc in this season reminds you that just because it’s a fantasy world doesn’t mean it can’t be real. I particularly loved Rex’s growth. To see a good-for-nothing ass work to earn his comeuppance is as rewarding as it is cathartic. SPOILER: It made his sacrifice in the Invincible War genuinely heartbreaking. But, my personal favourite in this whole bit was Cecil’s backstory. That’s one I won’t spoil. It was just… chef’s kiss!

And what of Nolan and Allen? Well, they continue to bond in the Viltrumite prison. While their’s was an afterthought or d-plot, the character moments and action sequences were nothing short of epic. Also, they reveal some secrets about the Viltrum Empire, planting seeds for the future seasons to reap.

Invincible Season 3 Ending Explained

Conquest (Jeffrey Dean Morgan) facing off Invincible in Season 3

Conquest (voiced by Jeffrey Dean Morgan) has come to accept Earth’s submission. He’s every bit as mad as the next Viltrumite, slaughtering innocents and decimating half the planet as he fights Invincible. He doesn’t even spare Oliver and Eve, which finally pushes Mark to push beyond his limits. Even with broken bones and mangled fists, Mark beats Conquest to near-death. Eve’s sudden breaking of her mental blocks allows her to use her powers to heal herself and incapacitate Conquest just enough for Mark to strike his finishing blows.

Confirming that Conquest is dead, Mark demands he be cremated, but Cecil—as expected—has his body stored deep underground in a rigged prison. His intention: learn everything about the Viltrum Empire if Conquest ever wakes up. In the aftermath, the heroes gather at Rex’s funeral, paying their respects. Mark admits to Oliver that maybe the only way to protect the planet is to kill villains, a moral dilemma that he’s been grappling with since the very beginning. Eve and Mark have professed their love for each other, and proceed to make love. However, Mark’s costume—which Eve takes off using her powers—lies in a glowing puddle of some strange liquid. Did Eve’s unlocking of her block also unlock some sort of ailment? We’ll have to wait to find out!

Angstrom Levy is healed by the Technicians, and they agree to find a new world for them in a very sinister tone. And lastly, Damien Darkblood—the demon detective who discovered Nolan’s malicious intent—summons a demon overlord, promising him a ‘surface dweller of unmatched power’. From context, I believe he’s talking about Eve, but again, we’ll have to wait to find out!

Is Invincible Season 3 Worth Watching?

Let me ask a counter—do you care?

Because if the previous seasons have made you fall in love with the characters, intrigued you with its world and intergalactic power-dynamics, broke your heart with their tragedies and made you smile with their moments of respite… then hell yeah! Season 3 delivers all that you’d expect of the next chapter of the Invincible story, without wavering in its quality. From the writing to the brutal violence to even its tender and sensitive character development, Invincible is one of the best superhero shows currently being produced.

In Conclusion:

How is it that some of the best superhero content of the year isn’t DC or Marvel?

Invincible continues to deliver compelling and emotionally rewarding episodes week after week. Season 3 really nailed it with Mark’s coming to terms with the reality of his situation, and embracing the harder choices that he has to make. If anything, I’m all the more excited for the next season!
