Link to season 4 trailer!
Image Comic’s Invincible was never expected to become so popular. At the time, head writer Robert Kirkman was working out of his house in Kentucky. With co-creator and illustrator Cory Walker right beside him. Kirkman (who you might know from the popular franchise, The Walking Dead) explains in an interview with Skybound, “The first year or two was rough…” Sales wise, the first few issues of Invincible did poorly, never making it past 400. Miraculously by issue 17# a small fanbase had grown and each weekly issue was selling in the early thousands.
So much so that in 2021, fans were rewarded with eight animated episodes from Prime Video, retelling the story and gaining a whole new wave of followers during the tail end of the pandemic. Superhero fans fell in love with the classic teenage hero story and the witty charm that made Invincible popular from the beginning, as well as how unafraid the series was to show a little entrails.
The concept of Invincible came from Kirkman’s own teenage years. He talks about feeling pressure to continue his father’s welding business and eventually translated that idea to feeling the weight of your father being the best superhero in the world and needing to live up to that.
Invincible follows the story of 17-year-old Mark Grayson, son of the world's most esteemed alien superhero, Omni-Man (Nolan Grayson). Nolan is from the planet Viltrum, home to some of the best warriors in the galaxy. He has also been planning to betray earth and all of its inhabitants since he arrived. A promise made to Viltrum to expand their empire using the cover of a superhero to gain trust. Mark navigates being half alien and gaining his powers, eventually becoming the hero that is Invincible.
Well, it’s been 5 years and the people still want more. After its third season ended in February of 2025, fans were rewarded with news of season 4 in March 2026. So what can we expect?
Character Development:
"There’s a storyline from the comic that I never got around to doing. Every superhero story has some chapter where they go to hell and they fight the devil. It happens in DC and Marvel comics. It’s a big deal," Kirkman explains in an interview with GameRant. Kirkman has been hinting for a while that season 4 will really show a transition of maturity in most main characters, not just Mark.
Mark is no longer a teenager and filled with a lot more drive for justice than we’ve seen in earlier seasons. He’s gotten over the moral block of killing and that’s a promised plot point in season 4. We also see him grow more out of Omni-Man’s shadow.
And maybe that’s a good thing considering half the damn galaxy wants to kill him and obliterate earth and will literally stop at nothing to do that. But that’ll come later!
Samatha Eve Wilkins, AKA Atom Eve, might get her redemption from the bummy writing we endured in season 3. Like her name hinted, Eve can rearrange and create atoms at her leisure, a “gift” from an admittedly sketchy government experiment on her pregnant mother.
Eve is Mark’s girlfriend and ever since they’ve gotten together she hasn’t really been more than that. She had so much spark and sass in earlier seasons and she was so independent and cool and they just killed that towards the end of season 3.
That was until the finale, where she and Invincible were faced with the challenge of defeating Conquest, an incredibly strong Viltrumite soldier sent to kill Mark and maybe his family while he’s at it. Conquest successfully kills Eve and Mark is rightfully devastated until Eve realizes she can rearrange space itself and literally revives herself like a neon pink phoenix.
But a brush with death wasn’t enough apparently, and we get the hint that Eve is pregnant towards the end of season three, and again in the trailer for season 4 when her powers don’t seem to work. While it hasn’t outright been said in the show, this is a direct translation from the comics.
Mark’s younger brother, Oliver, will also see a drastic change in season 4. He’s much older and much more eager to fight beside his father and Mark. He's always been eager to prove himself as a hero but now that he’s in his teens Mark won’t be able to control him as much. It seems Oliver still doesn’t understand how serious things are with his father but he’s far less naive and far less purple for that matter.
I’ve been a Nolan Grayson hater since my eyes graced issue one, but I'd be lying if I said his character arc isn’t impressive. He goes from homicidal machine loyal to Viltrum and ready to kill anyone who gets in his way, to a regretting mid-life crisis father who misses the life he had. In season 3 he betrays Viltrum to keep the planet he’s grown to love safe and is put in a space prison awaiting death.
Until his colleague Alan the alien breaks him out and they start plotting on how to save earth from Viltrumite invasion alongside a peaceful movement named The Coalition Of Planets. We’re left with the question of how far Nolan will go with his newfound humanity.
First look of Thragg's animated design The Viltrumite War:
Season 3 set us up for what is another direct translation from the comics, the inevitable war between Viltrum and Earth’s allies. So who is Mark Grayson against?
We know the horizons of the Invincible universe are broadening, with multiple important characters being introduced in season 4. The most anticipated amongst long-time fans being Viltrumite Grand Regent, Thragg. “The comic’s big bad is finally making his way to the screen. The king of the Viltrumites, Thragg, is finally shown in motion, with Lee Pace lending his vocal talents to bring the powerful ruler to life,” writes blog, ComicBook.com
We know from the comics, after Conquest fails to kill Mark he reports back to Thragg, who decides to send Conquest back on the same mission. This time, however, alongside two other Viltrumite soldiers. Meanwhile, a spy Thragg has inside The Coalition on planets parrots news of a push back against Viltrumite invasion, much to Thragg’s dismay.
These are dozens of loose ends and unfinished conflicts left from season 3 that we get to see in animated form come March and while the entire universe is shifting, fans can hope for the same charm we’ve had since season 1.
