**Warning: This article contains spoilers from the *Invincible* season 4 finale, "Don't Leave Me Hanging Here."**

Thragg is here to stay.

While the ending of *Invincible* season 4 wasn't as bloody as the penultimate deep-space brawl, it was no less tense. The truly invincible leader of the Viltrumites (Lee Pace) confronts Mark (Steven Yeun) back on Earth. And while the young superhero hallucinated Thragg's return all throughout the episode via PTSD-powered panic attacks, his worst fears — the villain destroying his home and everyone he loves — didn't come to pass.

Thragg is indeed on Mark's home planet now, but he's not there to destroy it. He wants to quietly live among humans in order to slowly procreate and rebuild the Viltrum race, just as Omni-Man (J.K. Simmons) was able to do with Debbie (Sandra Oh) in conceiving Mark. The alternate? Reject Thragg's proposed truce and face his forces again in battle, knowing how poorly everyone fared the last time.

Pace addresses this moment and what it means moving forward on the show, which has already been renewed for season 5.

"There's a measure of respect in it," the actor tells **, "and I think there's a measure of, 'You're here, I'm here. You're gonna have to deal with that, and I'm gonna have to deal with you, but I can't kill you yet, and you can't kill me, period.' So I think that's what it is, because he could just do it without even telling Mark that he was gonna do it. It's what Mark's been doing. So he could just surprise Mark with suddenly people are popping up with powers, but he's not doing that. He's doing this, and it's direct. He's saying, 'I rate you as a powerful, significant person. You could be the hero of this story.' So I'm gonna look at you dead in the eye and see what you're made of and see what you do with this.'"

*Invincible* season 5 doesn't currently have a confirmed premiere date, but it was announced back in July 2025. A video teaser showed the returns of Yeun, Simmons, Oh, Walton Goggins (Cecil Stedman), Gillian Jacobs (Atom Eve), and more back in the voiceover booth recording new material.

The question remains whether Mark will tell anyone that he made peace with the Viltrumites in exchange for allowing them to live quietly on Earth. Thragg promises Invincible will never hear from them again, but that feels unlikely.

"Maybe Mark will be an ally at some point," Pace posits. "He doesn't know that. All he knows is that he's gonna do this, and he's gonna do what he needs to do to get where he wants the Viltrumite people to be."
