The show strives to bring more complicated characters and intriguing storylines in each season. However, we as fans tend to have a favorite and a least favorite season. Here are the four seasons of the show, ranked from worst to best.

4 Invincible Season 1

Airing Date: March 25-April 29, 2021

No. of episodes: 8

The moment that Omni-Man revealed his dark side and killed the Guardians of the Globe was a turning point in the superhero genre. Invincible Season 1 couldn’t have kicked off the show in a more brutal way, showing that the series was here to topple all the existing tropes in the genre. It presented a complicated superhero tale, forcing us to change our perspectives a bit.

The show didn’t go for needless shock factor, but the big moments in the natural progression of the story came as extremely unsettling for fans. Especially if you’re not privy to the comic book material. However, compared to the rest of the three seasons, the first season does take its sweet time to establish the characters and setting.

The in-between episodes between the premiere and the finale had both high and low points. The latter half of the season has more tightly-knit episodes, leading up to a perfect finale.

Best episode: Where I Really Come From (S1.E8)

The season finale episode established Omni-Man as the most powerful and ruthless force in the Invincible-verse. Nolan went to destroy Chicago and killed hundreds, if not thousands, as part of his mission to annihilate Earth. However, he couldn’t complete his mission due to his love for the family and abandoned his post on Earth.

Omni-Man shows his powers in the most brutal ways possible, killing many people throughout season one. Still, the season finale came as extremely shocking for many fans. The episode not only set the stage for the rest of the show’s tone, but it also directly impacted storylines in future seasons. On IMDb, the episode is currently rated 9.7/10 (as of April 23, 2026).

3 Invincible Season 2

Airing Date: November 3-24, 2023 & March 14-April 4, 2024

No. of episodes: 8 (4+4)

Season 2 was no doubt a great follow-up to the explosive Season 1 finale. It brought in a powerful villain in the form of Angstrom Levy, voiced by Sterling K. Brown. The special episode on Atom Eve before the season gave us a strong reason to look out for her storyline in the season. However, it did frustrate many fans because of Prime Video’s greedy plan.

The studio made them wait years for a second season of Invincible, only to break the season into two parts with a four-month gap in between. Sadly, the season also didn’t make much improvement on the animation quality, which felt like a step down from the first season. It made fans question the longer gaps, since it produced no apparent results.

However, what lacked in the animation quality was made up for with amazing character developments, multidimensional storytelling, and incredible action sequences. The writing made it clear that the show wasn’t going to fumble like the later editions of the Invincible comic series. Luckily, the third season addressed these major issues.

Best episode: It’s Been a While (S2.E4)

The saving grace for Prime Video’s plan to split the season was the highly impactful mid-season finale. The episode featured Mark and Nolan’s fight against the Viltrumites to defend Thraxa. At this point, Nolan was trying to find redemption, which makes his involvement in the fight all the more significant. In a cliffhanger ending, Nolan was captured at the end of the episode.

There were several other highlights to the season, including Debbie’s struggle to come to terms with Nolan’s actions and Eve’s guilt over causing heavy losses. It was an episode filled with strong storytelling elements and brilliant voice acting. It is the highest-rated Season 2 episode on IMDb, with a rating of 9.2/10 (as of April 23, 2026).

2 Invincible Season 4

Airing Date: March 18-April 22, 2026

No. of episodes: 8

Invincible Season 4 arrived with a renewed sense of purpose, delivering one of the animated series’ strongest outings. Picking up in the aftermath of the devastating battle against Conquest and Angstrom, the new season wastes no time putting Mark Grayson through emotional turmoil.

His newfound moral code is not only leading him down a path of mental breakdown, but has also become a point of discussion for the Earth’s heroes. They are grappling with the conflict of whether killing is justified when the people they love are constantly at risk.

The Grayson family reunion is another significant event this season. Nolan and Debbie’s relationship is explored with great depth, and J.K. Simmons and Sandra Oh deliver some of their most powerful emotional performances. As the episodes progress, the long-anticipated Viltrumite War becomes the focus of the story.

Lee Pace’s Grand Regent Thragg is a menacing addition to the show. There’s a lot going on in the main storyline, but that doesn’t stop the season from giving us a few surprise villains like Matthew Rhys’s Dinosaurus and Danai Gurira’s Universa. The only issue with the series was some minor bumps along the way that slowed down the season, especially from the fourth episode.

Best episode: Don’t Do Anything Rash (S4.E7)

The penultimate episode of the fourth season is easily the best in the season. After hyping up Lee Pace’s Viltrumite leader Thragg for much of the season, the episode finally delivered on the season’s promises. He was able to hurt Nolan, Mark, and Oliver badly, but he was also dealing with the internal conflict of fighting against fellow Viltrumites.

Failing to take down Thragg, they are forced to resort to their Plan B. They used Space Racer’s Infinite Ray to destroy Viltrum, forcing Thragg and his fellow Viltrumites to invade Earth. The episode was rated 9.9/10 on IMDb, making it one of the highest-rated episodes (as of April 23, 2026).

1 Invincible Season 3

Airing Date: February 6-March 13, 2025

No. of episodes: 8

New black and blue suit for Mark Grayson, the long-awaited Mark-Eve relationship, the Invincible War, and Jeffrey Dean Morgan’s voice as the evil villain Conquest. All these factors make this third season the best among the bunch so far. It clearly edged out the previous seasons in terms of the high stakes, showing some of the best action-packed scenes in the show.

Comparing it with the latest season, Season 3 stood above the current season when it comes to the complex storytelling and the big moments. The show neatly tied in elements like Oliver’s questionable morality, Mark forced to kill the future tyrannical king Immortal, and Nolan & Allen’s bond in prison.

There wasn’t a dull moment in the season, and it all culminated in two of the best episodes across the show. In Episode 7, Angstrom sends his Invincible variants to attack Earth, who incur major losses to the Guardians and Earth’s heroes. As they fend off Angstrom’s attack, Conquest arrives on Earth, leading to the finale showdown. The animation falters a bit, but you can blame it on Prime Video and the declining budget for the show.

Best episode: I Thought You’d Never Shut Up (S3.E8)

The finale episode begins with the fight between Mark and Conquest, which also results in heavy losses on Earth. With the help of Eve and Oliver, Mark seemingly kills Conquest. However, we learn that Cecil captured a comatose Conquest and put him in a prison for interrogation. Angstrom is also back with his evil plans. And Mark strays off his moral compass, advising Oliver to kill anyone who threatens their family. The 9.9/10 rated episode on IMDb is the highest rated in the series (as of April 23, 2026).
