While there aren’t a ton of TV panels at WonderCon 2025, one of the biggies is what is technically titled “Dive Deep with Clips And Conversations with Prime Video’s Invincible.” In the wake of Season 3, EP Simon Racioppa, as well as several other behind-the-scenes folks hit the stage to talk about the game-changing season.
Here’s the official synopsis per the WonderCon schedule, and our recap of the panel follows!
Co-showrunner and executive producer Simon Racioppa, art director Dou Hong, and supervising producers and supervising directors Shaun O’Neil and Dan Duncan discuss key storylines and groundbreaking moments from season 3 of Invincible. The series is based on the award-winning comic book series by Robert Kirkman, co-creator Cory Walker, and contributing creator Ryan Ottley.
Kicking off, the discussion began talking about Season 3 finally being out in the wild. “Abject relief,” joked Racioppa. Hong, meanwhile, noted that her delight was going to the Invincible subreddit and looking at all the memes that get posted. “She finds the best meme,” Racioppa added.
Then the discussion turned to the growth of the show. Hong enjoyed how the show just simply got better, from the visuals, to the backgrounds… “The elevation of the animation and the story,” Hong said.
Then the breakneck speed of the panel turned to the moment from Season 3 where Mark Grayson (Steven Yeun) finally confessed his feelings for Atom Eve (Gillian Jacobs). After watching the clip from the show, Racioppa noted that a moment like this is a team effort, from the actors to the crew, to the composer. Duncan, meanwhile, added that there’s not a lot of difference between crafting a romance scene and an action scene — other than the speed.
On the scene in particular, Hong explained that a lot of what works is about the background artists… Setting it on a bridge elevated the scene and put the character models in the right place. She also lauded the show for taking time and allowing for pauses, something you can’t do in a 22-minute TV show. Racioppa agreed and noted that you have to care about the characters or it doesn’t work. Meanwhile, O’Neil recalled how the scene came back from “assembly” with some things messed up, and the team had to come in and smooth things over to get it ready for the final episode.
As for how it changes the plot? “Well, they weren’t dating before, and now they are,” joked Racioppa. More seriously, he explained that “there’s more story to come there. This is just one step.” Added Duncan, “They were friends, and now they’re partners… It raises the stakes… You care even more.”
Then it was over to Invincible War, and what the moderator called “The Multiverse of Markness.” In the episode, Yeun played 18 characters. “He came in, and we talked about each one,” Racioppa said. They tried to give each one something different in the dialogue, but Yeun brought more to the voices — and even the sounds he would make when he punched.
As for Hong, the process was confusing because they didn’t have them sorted by name — they were “Alternate Mark 001” and so on. She found that Hair Invincible was the trickiest one because he had long, luscious locks. She also recalled that because of all the horrible things in the show, she likes to space assignments out to various animators, so the horror gets spread around.
Then it was time to talk about adapting from the source material. “The comics are ground truth for the series,” Racioppa said, noting they find the “key moments we want to do” and then figure out where they want to flesh things out and make it all fit in an hour of TV. O’Neil noted they needed some “good silhouettes” for an episode, sent them to Cory Walker, and then he blew them out into full characters. Business Baby in particular was a favorite of the staff of that sort of thing, a character that was just sort of thrown in there.
Next scene showed off? Rex-Splode’s (Jason Mantzoukas) death during the Invincible War. Racioppa recalled spending two hours on ADR with Mantzoukas trying to get the scene just right. He also noted that on the evolution of the character, he went from a “lovable jerk” to a sacrificial hero. O’Neil clarified that he “didn’t change, per se.” He tried harder but was still a “lovable jerk” at the end of the day.
And then it was over to the big fight between Atom Eve and Conquest (Jeffrey Dean Morgan), as well as Invincible, in the final episode of the season. “We worked really closely with Robert [Kirkman] and Simon on this,” Duncan recalled. He lauded the script, as well as the sound helping immensely in selling the 30-minute-long fight scene. Added Hong, Invincible had “25 damage states” throughout the episode, based on how hurt he got hurt over the course of the episode. Conquest, meanwhile had “15, or around that.”
Talking about Morgan in the role, Racioppa said, “Getting him on board was a treat, a delight… Steven was particularly excited to have him on board.”
As for things they particularly enjoyed that weren’t mentioned, Duncan called out the fight between Mark and Cecil (Walton Goggins) in 3×02, O’Neil liked the prison break in 3×04, Hong liked the dating storyline between Rex and Shrinking Rae (Grey Delisle), and Racioppa was happy with how the ideological difference between Cecil and Mark played well with the audience.
Starting to wrap up, Racioppa teased on Season 4, “Maybe we’re going to see Damian back again, some great new cast that we can’t talk about… Mark is gonna punch some stuff, he’s gonna get punched too.”
With the remaining moments, the panel opened up into Q&A. Asked about the process for creating the show and how things changed, Racioppa called it an “organic” process, that sometimes things work in a comic book, but it won’t work as well on screen. Racioppa also teased that the villainous Thragg has been cast, but they can’t reveal who is playing him yet.
Then a fan asked about comparisons between Gambit’s death on X-Men ’97 and what happened with Rex-Splode. The answer was no, but Duncan noted he was watching X-Men while working on Invincible season 3. “Man, these guys did a great job,” he recalled thinking. “Now we have to do the same job, and we have to do it better.” Racioppa then joked that everyone is going to start doing it, with The White Lotus blowing up a skeleton and Reacher ending with him blowing up 20 skeletons.
Final question? A fan asked about confirming a rumor whether Spawn or Savage Dragon will show up in the next season. “No,” Racioppa said. “I cannot confirm that.”
And that was it for the panel! Invincible Season 4 will premiere likely in 2026.
