Fans of the animated series Invincible are bracing themselves for the release of the final two episodes of Season 3, which promise to deliver some of the biggest moments yet for the show. Season 3 has seen Mark Grayson, the titular character, grappling with the burden and complexity of being a hero, facing challenges on both personal and broader levels.
Prominent among the storylines is the evolution of Rex Splode, voiced by Jason Mantzoukas, who has transformed from a brash, immature character to someone genuinely striving for personal growth. Mantzoukas articulated his excitement about Rex’s development during our exclusive conversation. "I love it. I love it. I love it. You know, I read the comics, so I was hoping, truthfully, I was hoping we would get Rex's arc from the comics because there's so much there," he said, clearly intrigued by the depth the creators are bringing to the character.
Throughout the season, viewers have witnessed Rex face significant challenges, culminating from his past traumas. Mantzoukas poignantly shared on the stunted emotional growth of Rex due to his childhood, stating, "His emotional growth is tremendously stunted. You know, he is the trauma of his childhood and what he and Eve went through. All of this really has created a person who is closed off." It's through Rex's struggles and near-death experiences this season, viewers are now seeing him work to improve himself, proving the character's compelling nature.
With the Season 3 finale approaching, Mantzoukas expressed his anticipation for Rex's growth, teasing how pivotal moments would change his relationships with other characters. He humorously added, "Without having to bite his hand off, tell him it's time to grow up! It's time to be more empathic and more generous and kinder." This sentiment reflects the overarching themes of responsibility and empathy, which resonate throughout the series.
Meanwhile, Robert Kirkman, co-creator of Invincible, has hinted at some surprises as the animation adaptation departs slightly from the original comic book narrative. Kirkman noted, "We’ve kept the last two episodes secret for a reason. They’re the biggest episodes we’ve done so far, I think it’s very safe to say... Don’t think you’ve got it figured out. You may get something unexpected at the end." Such comments only heighten the suspense for the series' dedicated following.
The announcement of Conquest’s return promises to make the climax of Season 3 even more thrilling. Voiced by Jeffrey Dean Morgan, Conquest delivers chilling lines such as, "Stand ready for my arrival, worm... I am Conquest, and I am your last chance to fulfill your duty." Kirkman's assurance of Conquest’s eventual appearance has fans of the comics buzzing, even as he remained coy about the specifics of timing within the storyline. "I will say, Conquest shows up in the show eventually," he divulged, intentionally preserving some secrets for eager fans to explore.
With the introduction of Angstrom Levy and the farewell of various character arcs, the anticipation for the finale builds. The series draws closer to the Invincible War, and viewers can sense the impending conflict through the post-credits scene teases, with the upcoming episodes set to deliver epic battles and intense emotional resolutions.
Invincible Season 3 Episode 7, intriguingly titled “What Have I Done?” becomes available for streaming on Prime Video on March 5, 2025. The excitement doesn't stop there; just as audiences are tuning back, the final two episodes will drop on March 6 and March 13, enhancing the build-up toward the series’ much-anticipated conclusion.
Fans are not only invested due to the action-packed narratives but also because of the personal growth of characters like Rex Splode, who embodies the challenges of rising above one's past. Mantzoukas noted, "It's really fun to help watch this character grow up… it's cool as hell to play like a real side character who gets to have like main character growth." This relatable, compelling character arc emphasizes growth, redemption, and the inherent struggles of processing trauma.
After these explosive episodes, Invincible is also confirmed for Season 4, ensuring fans will continue to see the evolution of characters as they develop against increasingly formidable threats. The blend of personal stakes, comic book inspirations, and animated storytelling makes this series not only popular but also critically engaging.
With Season 3 drawing near its grand finale, viewers can expect emotional narratives and surprising twists as marked moments for Mark Grayson and his peers define the climactic end, setting precedence for future seasons. It’s truly where high stakes collide with characters growing under fire.
