Season 3 of Invincible: Key New Characters Revealed

With *Invincible: Season 3* set to premiere, Prime Video has unveiled a fresh wave of voice actors joining the hit animated series. Among the new additions are Aaron Paul as Powerplex, John DiMaggio as The Elephant, and Simu Liu stepping into the role of Multi-Paul, Dupli-Kate’s brother. However, the most tantalizing reveals also happen to be the least transparent—Breaking Bad’s Jonathan Banks and Hellraiser legend Doug Bradley have joined the cast, though their characters remain under wraps.

Given the timing and narrative trajectory of the show, it’s likely these casting choices are being kept secret to avoid spoiling key developments in Season 3. But that hasn’t stopped fans from speculating—who exactly could Banks and Bradley be voicing? And what about Christian Convery’s Oliver Grayson? Why is he aging so rapidly, and how will his new dynamic with Invincible shape the season? Let’s break down the most anticipated new characters for *Invincible: Season 3.*

Jonathan Banks as Conquest

Though Prime Video hasn’t officially confirmed it, the clues point strongly toward Jonathan Banks portraying Conquest—a ruthless Viltrumite warrior introduced in *Invincible #61* (2009). Known for his commanding presence and ability to embody hardened figures, Banks seems tailor-made for this role.

Conquest arrives on Earth bearing a grim ultimatum from the Viltrumite Empire: Invincible must either conquer his homeworld or be killed by Conquest himself. This sets the stage for one of Mark Grayson’s fiercest battles yet.

Season 2 already hinted at this conflict when Mark accepted his father’s legacy as Earth’s future conqueror. In Season 3, we can expect this storyline to escalate, forcing Mark into a solo battle against an experienced and brutal opponent. Despite his youth and inexperience, Mark will need to rise to the occasion—or risk not only his life but the freedom of the entire planet.

Doug Bradley’s Mystery Role

While Banks’ casting seems fairly straightforward, Doug Bradley’s involvement is more enigmatic. Famous for playing Pinhead in the *Hellraiser* franchise, Bradley is no stranger to villainous roles. So which antagonist from the *Invincible* universe will he bring to life?

Two names stand out based on the comic book arc and where the animated series currently sits narratively:

Dinosaurus

This character debuted in *Invincible #68* (2009) and serves as a post-Conquest threat. Dinosaurus believes humanity is destroying the planet and seeks to restore balance—even if it means wiping out major cities like Las Vegas.

Bradley’s deep, haunting voice would add weight to this morally complex figure, who sees himself as a savior rather than a destroyer. His ideology may even resonate with Invincible, making him a uniquely compelling adversary.

Grand Regent Thragg

The true big bad of the *Invincible* saga, Thragg is the ruler of the Viltrumite Empire and a central antagonist in the comics. He first appeared in *Invincible #11* (2004), yet remains absent from the animated adaptation—until now.

Thousands of years old and a master of every known combat technique, Thragg represents the ultimate test for Mark and Earth’s heroes. If Bradley is cast as Thragg, his chilling gravitas could elevate the series' biggest villain to terrifying heights. While Season 3 might only tease his full introduction, it would mark a pivotal step forward in the overarching story.

Christian Convery’s Oliver Grayson

Season 2 introduced Mark’s half-brother Oliver, born from Nolan’s relationship with a Thraxan woman. As a hybrid of Thraxan and Viltrumite heritage, Oliver exhibits extraordinary traits—including rapid aging and early signs of superhuman abilities.

By Season 3, Oliver will appear as a preteen despite being only months old, prompting Christian Convery to take over the role. Now capable of walking, talking, and even flying, Oliver embraces his destiny by donning a costume and adopting the codename “Kid Omni-Man.”

His presence introduces a new layer of complexity for Mark, who must now serve not just as a hero but as a mentor and protector. With Oliver eager to follow in both his and Nolan’s footsteps, Mark faces the challenge of guiding a powerful but unpredictable ally—one whose existence adds emotional stakes and potential danger to every mission.

In other *Invincible*-related news, the franchise is returning to print with the new prequel spinoff *Invincible: Battle Beast*. Set to debut in 2025, it’s already listed among IGN’s most anticipated new comics of the year.
