As the eagerly anticipated Invincible: Season 3 approaches, Prime Video has unveiled an exciting lineup of new voice actors set to join the series. Among them are Aaron Paul as Powerplex, John DiMaggio as The Elephant, and Simu Liu as Multi-Paul, the brother of Dupli-Kate. However, the most intriguing additions are Jonathan Banks and Doug Bradley, whose roles remain shrouded in mystery. Prime Video's decision to keep these roles under wraps suggests significant plot developments on the horizon.
Speculation abounds about which characters Banks and Bradley might portray. Additionally, fans are curious about Christian Convery's character, Oliver, and his rapid aging. Let's delve into the potential new characters we might see in this thrilling season.
Warning: Some mild spoilers for the Invincible comic series are included below!
Jonathan Banks as Conquest
Jonathan Banks, renowned for his role in Breaking Bad, is a new addition to the Invincible cast, though his character remains undisclosed by Prime Video. Given Banks' talent for portraying tough, seasoned characters, it's highly likely he will voice Conquest, a formidable Viltrumite warrior introduced in Invincible #61 in 2009. Conquest is known for his exceptional strength and battle scars, embodying the epitome of Viltrumite might.
In the series, Conquest's arrival follows a devastating conflict on Earth, presenting Invincible (Mark Grayson) with a dire ultimatum from the Viltrumite Empire: conquer Earth or face death. This sets the stage for one of the most intense battles Mark has faced yet. Season 2 laid the groundwork for this confrontation, hinting at Mark's inevitable clash with Conquest. As Mark grapples with his inexperience, fans can expect a gripping narrative as he struggles to survive against such a seasoned adversary.

Doug Bradley's Role in Invincible Season 3
While Jonathan Banks seems destined to voice Conquest, the role of Doug Bradley, known for his chilling portrayal of Pinhead in the Hellraiser series, remains a mystery. Bradley is likely to play a villain, and two characters stand out as possibilities: Dinosaurus and Grand Regent Thragg.
Dinosaurus, introduced in Invincible #68, is a complex villain with a mission to heal the world from human-induced harm. His unique perspective and actions, such as targeting Las Vegas for destruction, could be enhanced by Bradley's distinctive voice. On the other hand, Grand Regent Thragg, the primary antagonist in the Invincible saga, first appeared in Invincible #11. As the ruler of the Viltrumite Empire and a master of combat, Thragg's introduction could set the stage for Mark's ultimate challenge. Bradley's menacing presence would be a perfect fit for this pivotal character.


Christian Convery’s Oliver Grayson
Introduced in Season 2, Oliver Grayson is Mark's half-brother, born to Nolan on Thraxa. Oliver's unique heritage as half-Thraxan, half-Viltrumite results in accelerated aging, a key plot element in Season 3. By this season, Oliver, portrayed by Christian Convery, will appear as a preteen, already displaying his powers of flight and superhuman strength.
Oliver's rapid development will see him take on the codename Kid Omni-Man, following in his father and brother's heroic footsteps. His presence adds a new dynamic to Mark's journey, as he not only navigates his role as a hero but also guides his younger brother. Oliver's powers and potential vulnerabilities add tension to the narrative, as Mark fears for his family's safety amidst his battles.
