Now that Mark has defeated Conquest, we turn our attention to Invincible season 4 for whatever fresh hell is on the way. The likelihood is Thragg, another Viltrumite baddie, who's already been cast, according to Robert Kirkman.
On the back of the season 3 finale, he spoke to Variety about the show and what’s coming down the pipeline. The conversation turns to Conquest and Thragg, and the possibility of getting one since we've now already had the other.
Kirkman, who co-created Invincible with Cory Walker and Ryan Ottley and now oversees the animated show, remains coy. "I mean, it would certainly be weird if [Thragg] didn’t show up in the show," he said. "Here's what I'll say: He's been cast and he’s amazing."
He offers no more, leaving us to ponder the options. Thragg is a big role, since he's essentially the main villain of the whole story. The leader of the Viltrumites, he's a vicious, cunning, supremely powerful being and an existential threat to anything he deems unworthy.
In the comics, he's who Conquest answers to after failing to take down Mark, if you’d like a sense of the hierarchy. He’s bad news, and his presence would kick off a whole other phase for Invincible.
It stands to reason he'll be part of season 4, and probably quite early on, but we can only wait and see. The adaptation hasn't steered wrong yet, and we might get some small breathers before plunging into Thragg and all the ensuing twists he brings.
We might not be waiting long either, as Kirkman is hopeful the fourth season will arrive in 2026. Have a look at the upcoming superhero movies coming in the interim for other saviors who’ll be coming to our aid.
