Superhero, Invincible, doesn’t seem to have any intention of ending its run soon. It was initially confirmed by Amazon Prime Video that the animated series will continue with the fifth season, and with season 4, it is officially scheduled for 2026. After all the surprises that were revealed at SDCC 2025, like new characters, major comebacks, and surprise castings, fans are literally on the edge of their seats, waiting for the next most intense chapter.
There is a question of who could be the strongest if there were so many powerful heroes and villains, is raised, aren’t it? Here are the ten most powerful characters of Invincible Season 4 that most probably exist, with those at number 10 being the least powerful and the one at number 1 being the most powerful.
10. Business Baby
Business Baby may seem like a regular infant, but in fact, he is the most different of the most different. This little dynamo early on made it clear that the principle of size does not apply to throwing a good punch. He is quick, indefinable, and always finding a way to be resourceful; he has never failed to both stun the public and the antagonists with his antics. Of course, his fight against Stripe was not successful, but his quickness and ruthless fighting style are the reasons why he is thus an unforgettable underdog.
9. Cecil Stedman
One of the best things the Global Defense Agency has done is to put together a mastermind like Cecil. In essence, he is very much similar to what Nick Fury is to the Marvel Universe, but if Fury were notably tougher and could command a legion of re-animated soldiers, with a scarier edge and power at his disposal. Without the extra-human abilities, he still is an impressive force through his brain-power and cold-bloodedness. His turning to logic almost exclusively and his willingness to be involved in any dark dealings necessary for saving the human race indicate that he is even more dreadful than the majority of supervillains.
8. Shapesmith
Voiced by Ben Schwartz, this Martian shapeshifter takes adaptability to the next level. Shapesmith can stretch, morph, and even rebuild himself after sustaining injuries that would kill anyone else. He is not quite in the same league as the Viltrumites in raw power, but his creativity, persistence, and heart keep him in the fight no matter the odds.
7. Bulletproof
Zandale Randolph, aka Bulletproof, is fast, powerful, and fiercely determined. He can fly, regenerate, and deliver devastating blows-pretty much everything but his name might be a bit of an exaggeration. What truly defines him isn’t invulnerability, though, but his relentless willpower. He’s the kind of hero who refuses to back down, no matter how impossible the situation seems.
6. Robot
Zachary Quinto’s Robot is the perfect combination of a genius and machinery. With his enhanced body, advanced weaponry, and army of drones, Robot will dominate almost any battlefield. But what really makes him so dangerous is his brain-he can conceptualize and outmaneuver most opponents before they’ve even realized their loss. He’s proof that brains and strategy can be just as deadly as brute strength.
5. Atom Eve
Few heroes are as capable or as adored as Atom Eve. Voiced by Gillian Jacobs, Eve can manipulate molecular matter itself, giving her nearly limitless creative control over her surroundings. She can heal, fly, build, and destroy with a thought. In short, if Eve ever decides to unleash her full potential, she could reshape the world entirely. She’s not just strong, she’s practically a one-woman army.
4. Dinosaurus
During Comic-Con 2025, it was a big-time news that Matthew Rhys would lend his voice to Dinosaurus in the eponymous season of Invincible, and the fans went insane with joy. As the techiest, Dinosaurus from the comics is the terrifying side of the David Anders character that is not only powerful but also complicated. When David’s loss of control of his emotions, he changes into a giant, dinosaur-headed creature, and the destruction of a city is the least of the things it can do. Apart from the mighty power, it also has a deep moral struggle hidden under the demolition. It is the combination of havoc and humanity that makes Dinosaurus such a fascinating character in the series.
3. Allen the Alien
Seth Rogen is re-voicing for Allen the Alien, and by the way, he is taking it to a whole new level this time. According to the official announcement, the ensuing season is going to be all about the clash between Doom and Predator-like creatures for the Viltromite. Allen has almost superhuman strength, super speed, and virtually unlimited stamina. Besides these, he also possesses telepathy and regeneration to the point of being immortal. He is one of the very few individuals who may actually challenge Invincible himself. It is a pretty safe bet that we will be seeing intergalactic battles of epic proportions in Season 4 with his comeback.
2. Omni-Man
The legend himself, Omni-Man, voiced by J.K. Simmons, remains, perhaps, one of the most feared beings in the Invincible universe. With near-limitless power, speed, and fighting skill, he’s essentially a living god… one with serious anger issues. Whether he acts as a hero or villain depends on the day, but one thing is certain: no one wants to be on his bad side.
1. Thragg
And at the very pinnacle of the power rankings is Thragg, Grand Regent of the Viltrum Empire, the ultimate Viltrumite: everything Omni-Man is, only stronger, faster, and far more ruthless. His coming promises chaos on an intergalactic scale and paves the way for an all-out Viltrumite war. No one is safe when Thragg comes knocking-not even Invincible himself.
SDCC 2025 gave them plenty to chew on from first looks at Dinosaurus to confirmation that this fourth season will dive deep into the Viltrumite conflict. By the time it comes, this promises to be the most brutal, emotional, and jaw-dropping season yet, judging by the sheer levels of power depicted. So buckle up-Invincible Season 4 isn’t just another fight; it’s an all-out war.
