Invincible Season 4 Review:

Invincible is one of those consistently great shows that I look forward to every year. The writing in particular continues to push every character to their limits, while building their personalities that pushes the narrative forward in interesting, emotionally testing ways.

Season 4 continues that trend, following the events of Season 3. While Mark (Steven Yuen) grapples with his growing cynicism and the public’s growing negative perception of him, Nolan (JK Simmons) colludes with the Coalition of Planets to prepare for war against the Viltrumite Empire. Both these plots are exactly what you’d expect them to be. Emotionally charged, narratively spectacular, and visually stunning (except when the animation seems a little under budget).

The Stakes Keep Rising Higher & Higher

Season 3 left all our characters in quite a mess. Mark, Oliver (Christian Convery) and Eve (Gillian Jacob) reel from their fight with Conquest (Jeffrey Dean Morgan). While they recover physically, the emotional scars left on them affect not just their relationships, but also the way the world sees them. Particularly Invincible. It’s like every season is hell bent on making the world hate him just a little bit more. After Omni-Man’s betrayal, and the Invincible War, he has grown darker, more sceptical. He doesn’t hesitate to kill his enemies. Naturally, that’d make Cecil (Walton Goggins) wary of him. After all, humanity’s best bet against the Viltrumite Empire is just a kid with anger issues, continuing to deal with PTSD from his recent traumas.

Nolan, on the other hand, continues his journey with Allen (Seth Rogen), which brings him face to face with Thaedus (Peter Cullen). The Coalition of Planets is planning a war against the Viltrumites, and Nolan and Mark are their best bet in winning. This entire plot revealed so many heartbreaking, thought-provoking details of Nolan’s past as well as the Viltrumite Empire’s origins that I can’t help but wonder what the future of this war is going to look like. I have not read the comics, which makes watching this show a wholly epic experience.

The main A & B plots of Season 4 really kick things into higher gears. From the progression of conflicts to the world building, everything was stellar. Yes, the animation did feel underwhelming at times, but the story remained solid for the most part.

Brilliant Character Work

While the Guardians didn’t get as much screen time, we did get Eve and Debbie (Sandra Oh) dealing with domestic life. Debbie’s relationship with Paul (Cliff Curtis) grows. I loved how she moves on, grappling with this messy life after Omni-Man’s betrayal. Even when Nolan faces Debbie again, their interaction was as viscerally charged with emotions as can be. And the resulting complications with Oliver as a result of what he overhears… beautiful! However, I’ll admit that I found Eve’s pregnancy to be an underutilised plot point. I didn’t like seeing her sidelined like this. Her powers reacting strangely was a nice touch, but we only got that in the first couple of episodes. On the character front, Eve’s arc was my least favourite.

That said, I really liked every single diversion in the plot. From the Devil (Bruce Campbell) & Volcanikka (Indira Verma) to the return of Battle Beast (Michael Dorn) & Damien Darkblood (Clancy Brown), almost every secondary character added something new and interesting to the overall season. Even Thragg (Lee Pace) and the Viltrumites’ cultural justification of genocide makes sense from the problematic perspective of these tyrants, making you ponder over real world events, historic and current. Where mainstream superhero films offer black-and-white explorations of simplistic ideas, each character in Invincible manages to complicate scenarios, really compelling viewers to consider the implications of the events unfolding. No action goes without consequence, and those consequences are always realistically handled. Nolan doesn’t get off the hook easily.

While Season 1 was interesting, every subsequent season has continued to impress me beyond what I thought was possible. The characters are a huge part of the reason why I love this series so much, and I hope the makers maintain this quality until the story ends.

Invincible Season 4 Ending Explained

Our heroes rush back to Earth, only to find Earth is safe and sound with no Viltrumites around. Mark keeps having nightmares of Thragg killing his loved ones. He makes sure Debbie is fine, then goes to check on Eve. Nolan meets Debbie, only to get scolded for letting Oliver get hurt. She refuses to let him stay in their house. Debbie’s relationship with Paul has also not worked out, them having broken up during Mark’s absence.

Mark reconnects with Eve, voicing his worries. His nightmare visions keep getting brutal and worse. Eve later confesses to having an abortion. She didn’t want Mark to think of the baby, instead wanting to come home alive after the Viltrumite War. Her loneliness made her go ahead the abortion. Mark apologises for not being there for her, and remains supportive of her.

Nolan goes to the site of his fight with Mark, regretting his words and actions. Cecil meets him there to get information about the Viltrumites. Nolan apologies for his actions, revealing that the Coalition of Planets don’t know where the surviving Viltrumites are hiding. He informs Cecil that the Coalition is installing an early warning system for Earth.

Members of the Coalition argues genocide over the Viltrumites, which unsettles Allen, their new leader. Nolan informs his decision to return to Telescria. Debbie demands he take her with him so she can see Oliver. They depart, and Debbie is fascinated by the view while leaving orbit, a hint of her and Nolan’s relationship improving marginally.

Cecil expresses his dissatisfaction over the whole situation, when Mark has another flash of Thragg. He requests help with professionals to deal with it. Later, Eve suggests Mark fly out to relax. However, that’s when Thragg confronts Mark, confirming the Viltrumites’ presence on Earth. He reveals that only 37 of them remain, and should be enough to destroy Earth. However, he only wants a home, and the Viltrumites will integrate into human society. Humans will never know of them, but the Viltrumites will use humans to repopulate and rebuild their race. If the Coalition attempts to hunt them, the Viltrumites will decimate Earth. Thragg proposes peace to allow the Viltrumites to do so. Mark reluctantly agrees, hoping it’ll keep Eve and Debbie safe.

In the end, Allen complains about paperwork to Elia (Tatiana Maslany). She gives him a recorded message from Thragg. He believes that the only way to keep the universe safe is to eradicate the Viltrumites. He then gives Allen the location of the perfected formula of the virus. Even humans might be vulnerable to it, but for the good of all living beings, he demands Allen use the scourge virus.

Is Invincible Season 4 Worth Watching?

Yes. Invincible is a brilliant show that’s consistently good, and deserves all the attention and praise it’s getting.

Will there be an Invincible Season 5? The series was renewed for a fifth season already in July 2025. So, yes. And I can’t wait for it to drop!

In Conclusion:

Invincible Season 4 packs a brutal punch with Mark growing volatile in the wake of season 3, as well as Nolan and Allen’s war against the Viltrumite empire. Man, I really can’t wait for Season 5.
