‘Invincible’ Voice Cast: Who’s Who In Season 4, Episode 2, Including Space Racer And Thragg?

We’ve got three episodes on Invincible Season 4 premiere day, which means a slew of voice cast actors showing up and doing their thing. Wondering about Season 4, Episode 2 “I’ll Give You The Grand Tour”? Who plays Space Racer, Thragg, and Young Nolan? Don’t worry, we’ve got your answers right here.

Before we get there, though, a brief recap for context, and spoilers past this point (though you can get a longer Season 4, Episode 2 recap on our podcast). The episode starts in a surprising place: Viltrum, back when Omni-Man was a teen and a teacher. He didn’t really pass his rite of passage (fighting his parents), but moved on to his next stage in the Empire… Only for billions of Viltrumites to get killed by The Scourge Virus, which we later discover was created by Thaedus, leader of the Coalition. Not only that, Thaedus is the great betrayer, having slain the former leader of the Empire, leading to Thragg’s ascension.

In any case, we learn all this so that Allen the Alien can understand why Nolan will help the Coalition gather weapons Nolan teased in his sci-fi novels, but won’t join their battle against his former home. Instead, the duo, and Allen’s horny girlfriend Telia, head off on a parody of the Star Trek: The Next Generation ship to gather these Viltrumite killers.

Those include Space Racer, a guy with a gun that can shoot through planets, some venomous bugs, and Rognarrs, unstoppable beasts frozen on their planet. It also includes Tech Jacket, who is back on Earth, which is where they’re headed by episode’s end. Oh, and not only has Thaedus improved the Scourge Virus to kill all Viltrumites (himself included), but Conquest is back with Thragg. Uh-oh!

Invincible Season 4, Episode 2 “I’ll Give You The Grand Tour” Cast: Who’s Who In The Voice Cast?

We won’t break down the full cast (you likely know who plays Invincible by now), but let’s discuss some of the highlights from this space-set episode.

First up, Scott Aukerman is the voice of the Picard-esque The Captain. He’s best known for his comedy podcast Comedy Bang! Bang! though he also recently wrote a fun digital Spider-Man comic. Voice legend Troy Baker, who played Joel in The Last of Us games, as well as Batman, The Joker, and more, makes his Invincible debut as “Male Viltrumite” and “Geldarian Warrior.” Huh!

Cleveland Berto, who previously voiced Darkwing II, shows up as a Viltrumite General, while Clancy Brown (The Shawshank Redemption and Mr. Krabs on SpongeBob to name a few) reprises his role as General Kregg, while Optimus Prime himself, Peter Cullen, is back as Thaedus.

Of the big new voices, Winston Duke — M’Baku from the MCU, and starring roles in Us — is Space Racer. And Lee Pace, who you may know from Pushing Daisies or Foundation, is the voice of Thragg. Also of note, the awesomely named Talon Warburton plays Young Nolan, and yes he is the son of the voice of The Tick, Patrick Warburton.

Tatiana Maslany of Orphan Black is back as Telia, and Seth Rogen is, of course, still Allen the Alien.
