Meet The Invincible Season 2 Cast: Steven Yeun As Mark Grayson, AKA Invincible

Invincible Season 2 is almost here! The final episode of the first season of the animated Prime Video show streamed on April 30, 2021. But as of this week, the show is finally returning for most of a second season full of all-out action in the incredible Invincible style. And with that in mind, we’re going to introduce (or in this case reintroduce) you to some of the cast. Who better to start off with than Steven Yeun as the voice of Mark Grayson, aka Invincible himself?

Based on the comic books by Robert Kirkman, Cory Walker, and Ryan Ottley, Invincible wouldn’t work without the title character. So let’s go, and break down what you need to know about Invincible, what happened to Invincible in Season 1, and Steven Yeun, the actor who voices him on Prime Video.

Who Is Invincible, aka Mark Grayson, On Invincible?

Invincible - It's About Time

Pretty dumb way of phrasing this? But let’s get into it anyway. Mark Grayson is the son of Nolan Grayson (voiced by J.K. Simmons) and Debbie Grayson (Sandra Oh). He’s a regular teenager attending high school. Sort of. Secretly, his father is Omni-Man, one of the greatest superheroes in the world. And Mark is just anxiously waiting for his own powers to come in.

They do, and he slowly figures out he’s now super-strong, can fly, and is mostly invulnerable. In fact, despite taking on the name Invincible as a superhero, he’s pretty vincible… One of the main features of both the show and comics is that Invincible regularly gets beaten to a pulp. However, he luckily heals fast as well, thanks to the fact that he’s half Viltrumite — the alien race his father belongs to.

Oh yeah, that. While most of Season 1 Mark spends exploring his powers and trying to live up to his dad’s legacy, there’s a big secret at the heart of the show that upends everything Mark thinks is true.

What Happened To Invincible At The End Of Invincible Season 1?

Yeah, so Omni-Man wasn’t quite on the up and up about being a magnanimous, helpful superhero. In fact, the Viltrumites are a race of conquerors. They’re so strong, they can go solo to a planet and take it over. However, they also look to breed with the local populace and create helpful little half-Viltrumites like Mark.

Once Mark discovers this in the Invincible season finale, and it’s revealed that Omni-Man murdered the superhero team the Guardians of the Globe — something we, the viewers, knew since the Invincible series premiere, but Mark found out late in the game — he refuses to join his father. Classic Darth Vader/Luke Skywalker-style moment, except somehow Omni-Man takes it way worse than Vader. In order to show Mark how he views humanity, as disposable garbage they’ll long outlive, Omni-Men essentially uses Mark’s body to wreck an entire city, tear a subway car (and everyone in it) in half, and then pummel him on a mountaintop.

He also tells Mark he views Debbie — his wife — as more of a “pet” than a human, something she overhears in devastating fashion. Before delivering the killing blow, Omni-Man asks Mark what he’d have after everything else in his life was dust and gone. “You, Dad,” Mark says. “I’d still have you.”

This, more than any punch, throws Omni-Man for a loop. Despite everything the villain said, perhaps he does feel something for Mark after all. He flies away, leaving Earth behind and Mark near death on a mountain.

However, there’s more to come. “Where I Really Come From” ends with the cast grappling with the ramifications of Omni-Man’s actions. For Mark, that means dealing with a now distraught mother, a superhero friend, Atom Eve (voiced by Gillian Jacobs) who supports him but has her own things to do, and a girlfriend, Amber (voiced by Zazie Beetz), who also supports him, but may never understand what he’s going through.

What’s Next For Mark Grayson In Invincible Season 2?

Going into Invincible Season 2, Mark is going to have to figure out how to balance being a superhero with the knowledge that he was literally bred for evil. As the Season 2 trailer teases, it looks like Mark has gone bad and taken over the world; but chances are, that’s an alternate dimension.

That’s because Season 2’s big threat, at least initially, is Angstrom Levy (voiced by Sterling K. Brown), a man who can travel the multiverse. Don’t worry, as usual with Invincible we’re not getting into complicated multiverse theory here like some other superhero franchises… Things will be simple, and fun. Until they’re horrifying and sad. That’s it, that’s the show!

Also, for fans of the comics, without getting too much into spoilers, we might expect some potential romantic complications for Mark, as well…

Who Plays Mark Grayson On Invincible? What To Know About Steven Yeun:

You almost definitely know Steven Yeun at this point, but fans first became aware of the actor thanks to his role as Glenn Rhee on The Walking Dead, another show based on Robert Kirkman’s comics. He was born in Seoul, Korea in 1983 as Yeun Sang-yeop, before taking Steven Yeun as his professional name. He was very into comedy in Chicago and took a few bit parts before blowing up as part of AMC’s hit zombie series.

Since then, he’s steadily built an impressive career in critical hits like Okja, Burning, and Minari, the latter of which earned him an Academy Award nomination for Best Actor. He’s also starred in Jordan Peele’s Nope and on Netflix on Beef.

Yeun has also voiced a ton of roles on TV, including in Trollhunters and Voltron. Though personally I highly recommend you check out his work opposite Beef co-star Ali Wong on Tuca & Bertie, as the earnest bird-boyfriend Speckle.

Coming up, Yeun is playing a mystery role in Marvel’s Thunderbolts, which should be pretty cool if you ask me.

He’s not particularly active on social media, but you can follow him on X (formerly known as Twitter), where he hasn’t posted anything since February; or on Instagram, where has no posts and 3.6 million followers. Good luck with that!
