Right from its very first episode, Invincible has proven itself a consistently great superhero series. The art style is fantastic, the writing is excellent, and the series boasts a wonderful cast of characters. Of course, most of the show revolves around the titular hero, but there are a bunch of other compelling main and supporting characters that add a lot to the overall experience, too.
While the writing is a big part of what makes them good, the people who truly bring them alive are the actors who provide their voices. To celebrate them, here are all the series’s characters and their voice actors.
Shapesmith
Ben Schwartz
Shapesmith is a Martian who can shapeshift into pretty much anyone. He uses this power to come to Earth and live among people. For the most part, he’s a comic relief figure, but he does have a major role in season two and the Sequid Invasion arc. While seasons two and three are the ones he featured in the most, he actually debuted in the first season.
Invincible: 10 Best Fights
Some of the best fighting in any animated superhero series belongs to Invincible with its incredible animation, drama, and violence.
The comedic character is brought to life by Ben Schwartz. Many will know the actor for his recurring role in Parks and Recreation as Jean-Ralphio. Yet his fame grew even further in the 2020s as the voice of Sonic the Hedgehog in Paramount’s very successful Sonic films. He’s also appeared in all sorts of other comedy films and series over the years.
Conquest
Jeffrey Dean Morgan
Conquest is a very powerful member of the Viltrumite Empire, making him a major antagonist. In season three, he is sent to Earth, where he tussles with Invincible. The third season is where he makes his introduction, but he remains a major character in season four.
Providing the voice of Conquest is Jeffrey Dean Morgan. Conquest is not the first intimidating villain he has ever played. He also famously portrayed Negan in The Walking Dead Series. Other popular series he’s appeared in include Supernatural, Grey’s Anatomy, and The Boys. Morgan has also appeared in films such as Watchmen and Rampage.
Thragg
Lee Pace
Thragg is the leader of the Viltrumite Empire, which makes him a very important character in the series. That said, he doesn’t make an appearance until season four. However, his presence is felt long before that due to the cruelty the rest of the Viltrumites are doing, presumably under his orders.
The villain is played by Lee Pace. The actor has featured in a few major franchises. For example, he played Ronan the Accuser in the Marvel Cinematic Universe and Thranduil in The Hobbit movies. He also stars in the series Pushing Daisies and has appeared in plenty of films.
Thaedus
Peter Cullen
Most Viltrumites are very loyal to the Viltrum Empire. One who is not is Thaedus. He betrayed that evil empire and intends to stop their terror. So, he mentors and guides Allen the Alien. He initially appears in season two before reappearing in season four.
The man behind Thaedus’s voice is Peter Cullen. The actor is best known for voicing Optimus Prime in various Transformers shows and movies, most notably the 1980s animated series. He’s also Eeyore in many Winnie the Pooh projects, so he’s tied to a few iconic characters. Alongside them, the actor has lent his voice to a number of other TV and film characters over the years.
Oliver Grayson
Christian Convery And Lincoln Bodin
Oliver Grayson is the son that Omni-Man had with Andressa, making the kid half Viltrumite and half Thraxan. However, he lives back on Earth with the Graysons. He is first introduced partway through season two and has become a regular since.
Christian Convery, a young actor known for Cocaine Bear, 2025’s Frankenstein, and the Sweet Tooth series, primarily plays Oliver. The toddler version is portrayed by Lincoln Bodin, who has appeared in 9-1-1: Lone Star and The Accountant 2.
Angstrom Levy
Sterling K. Brown
The second season of the series introduces Angstrom Levy. He is a brilliant scientist who knows how to traverse through different dimensions. Yet, an accident disfigures him, drives him mad, and makes him want revenge on Invincible. This is what drives him for the rest of season two and three.
Playing the mad scientist is Sterling K. Brown. You may know him from his role as Randall Pearson in the drama series This Is Us. He also portrayed Christopher Darden in the limited series The People v. O.J. Simpson: American Crime Story. On top of that, he’s been in the likes of Black Panther and Frozen 2.
Allen The Alien
Seth Rogen
Allen is a friendly and quite goofy alien who attempts to recruit the most powerful warriors to take on the Viltrum Empire. He played a minor role in the first season, but he became more important from season two onwards.
The person voicing Allen is Seth Rogen. He is a very famous actor and filmmaker. He’s best known for his work in comedy films, including The 40-Year-Old Virgin, Superbad, and Knocked Up. He also writes and stars in the Apple TV+ series, The Studio. Plus, he’s voiced characters in big animated movies like Kung Fu Panda, Monsters vs Aliens, and The Super Mario Bros. Movie.
Kregg
Clancy Brown
Kregg is a member of the Viltrum Empire. In fact, he is a very high-ranking member of that empire, meaning he’s both evil and very powerful. The character debuted in the second season and has since featured heavily.
Clancy Brown is the actor who helps bring the character to life. He also does the same for Damien Darkblood, who is a significant character from the first season. Ka-Hor, Bryant, and The Hunk are other Invincible characters he voices. Outside of the series, he has had a long career in film and television, so he has a lot on his resume. This includes The Bride, The Shawshank Redemption, Starship Troopers, Star Wars: The Clone Wars, Thor: Ragnarok, and many more. His most famous role, though, is arguably as Mr. Krabs from SpongeBob SquarePants.
Amber Bennett
Zazie Beetz
Amber Bennett mainly serves as a love interest to Mark Grayson. The two of them date for a while, and their relationship ends up being difficult due to Grayson’s superhero duties. Despite just being a love interest, she features quite heavily in the first two seasons. Her role diminishes in the third season, though.
The role of Amber is played by Zazie Beetz. She is an actress who is arguably best known for portraying Van in the series Atlanta. Yet, many people will also recognize her as Domino from Deadpool 2. She’s also done a bunch of other TV and film work during her career, including starring in a Black Mirror episode and appearing in the movie Bullet Train.
Donald Ferguson
Chris Diamantopoulos
Donald works at the Global Defense Agency as an assistant to Cecil. He appears in every season, and at first, he seems a minor character, but his importance grows over time.
The character is voiced by Chris Diamantopoulo, who also voices a few other people in the show, including Todd, Isotope, Doc Seismic, Vidor, Pete, Jerry, Force Fist, and a few nameless characters. Outside of Invincible, he played Russ Hanneman in the Silicon Valley series, and he’s also voiced Mickey Mouse in a few projects.
