Invincible’shierarchy of power instantly changed upon Conquest’s arrival at the end of season 3, but after Robert Kirkman’s latest tease, I’m confident an even more powerful villain is on the way for season 4. After the emotional and violent Invincible War, Mark Grayson didn’t get a moment to rest as he was forced to battle Conquest duringInvincibleseason 3’s ending, offering a reminder of just how powerful Viltrumites are.We’d already seen the likes of Anissa and Omni-Man demonstrate extreme power, but Conquest looked even more formidable, only being bested after toying with Mark and his loved ones.
It felt like Conquest could have killed the protagonist at any moment, but he enjoyed finally having a competitive fight too much, allowing Atom Eve to hit him with a powerful blast before Mark took him down. Despite his defeat,Conquest could still return inInvincibleseason 4after Cecil chose to keep him alive, but he might lose his crown as the show’s strongest villain after a major update from Robert Kirkman. The franchise creator confirmedInvincible’s main antagonist has officially been cast, indicating he could debut in season 4, adding an even more menacing threat to the series.

Robert Kirkman Officially Confirmed That Thragg Has Been Cast In Invincible
The Franchise’s Biggest Villain Looks Destined To Debut In Season 4
In an interview withVariety,Invinciblecreator Robert Kirkman announced that Thragg had officially been cast, which has since been confirmed by the show’s officialTwitteraccount. Considering he is the story’s central villain in the source material, having Thragg’s casting finalized is a big deal, and this early announcement suggests he could make his Prime Video debut in season 4. Naturally, details about when he might show up have been kept quiet, and there’s no guarantee he will feature in season 4 for sure, but it seems incredibly likely based on all the details we’ve gotten so far.
Highlighting that Thragg had been cast shortly after season 3 finished would be a bold strategy if he didn’t at least have a cameo in season 4, and with Robert Kirkman aiming for somewhere between seven and ten seasons in total, his arrival must come sooner rather than later. Therefore, it seems likeInvinciblewill have a new most powerful characterwhen the show returns. He is easily the most menacing villain in the comics based purely on his incredible strength, and assuming he replicates that in the series, his involvement is sure to be both exciting and terrifying.

What Thragg’s Potential Involvement Means For Invincible Season 4
Invincible Season 4 Will Have Higher Stakes Than Ever
With Thragg’s season 4 involvement looking inevitable,Invincible’s future seems like it’s about to change. The ending of season 3 suggested there are still other storylines that will be at the forefront when the show returns, as the Sequid invasion is certain to get its own dedicated episode. Additionally,Damien Darkblood’s return inInvincibleseason 3’s mid-credits scenehints at a scrapped comic storyline taking center stage, but Thragg’s presence means the show will also build towards its main Viltrumite storyline. As a result, the stakes will be higher than ever, and the violence will only get more brutal.
Season 3 already upped how graphic and bloody the fight sequences were, but Thragg’s sinister nature will amplify this even further. He will also add more jeopardy to the series, asRex Splode’s death during the Invincible War proved that very few characters can be considered safe, a fact that Thragg’s arrival will double down on. The Viltrumite will completely alterInvincible’s power scale by making Conquest look tame in comparison, and his ruthless nature is bound to put even more pressure on Mark as he attempts to fight back against the Viltrum Empire.

Having Thragg around should also make the Coalition of Planets more important and give Omni-Man and Allen bigger roles.
Having Thragg around should also make the Coalition of Planets more important and give Omni-Man and Allen bigger roles, giving the story even more layers. While his most evil moments may not happen until season 5 or beyond, Thragg’s potential involvement in season 4 forces every hero to be on their toes and suggests there will be less time for jokes as the action gets more serious.

Who Could Play Thragg In Invincible?
AlthoughInvinciblehas confirmed the voice of Thragg has been found, it remains a mystery as to who has been cast as the villain. While there are no immediately obvious candidates,the connections betweenInvincibleandThe Walking Deadsuggest someone Kirkman has worked with previously could have snagged the role.Invinciblehas featured severalWalking Deadactorsthroughout its three seasons, with Jeffrey Dean Morgan being the latest actor to join the superhero franchise after years in Kirkman’s zombie universe, meaning this trend may continue.
Invincible Cast & Character Guide: What The Voice Actors Look Like
Amazon Prime Video’s animated Invincible TV show is now out. Here’s every cast member who appears and which comic characters they play.
Assuming Kirkman does look at his vastWalking Deadcast once more, Jon Bernthal could be a strong choice, as he has great experience with playing violent tough guys. He also has incredible range and could display many of Thragg’s dominant, arrogant, and cruel personality traits. Michael Cudlizt would be another interesting choice for the role, as he appeared in season 1 as Red Rush and could come back as a completely different character, having a much bigger impact. After all, Clancy Brown has proven Kirkman is happy to let one actor do multiple voices, so why not Cudlitz?
David Morrissey is another name that Kirkman has relied on to play a leading sinister villain, and he could be a great fit as Thragg based on his performance as the Governor inThe Walking Dead. IfInvinciblewere to go for someone who hasn’t been involved in either of Kirkman’s two hit franchises, Ron Pearlman may be a fan favorite. He has featured in countless animated projects - frequently playing villains - and there’s no doubt he would leave a lasting impression as Thragg, provingInvincibleis spoiled for choice when it comes to casting its main villain.
