As the highly anticipated Invincible: Season 3 approaches, Prime Video has unveiled an exciting new lineup of voice actors set to join the series. Among them are Aaron Paul as Powerplex, John DiMaggio as The Elephant, and Simu Liu as Dupli-Kate's brother Multi-Paul. However, the most intriguing additions to the cast 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 is rife about which characters Banks and Bradley might portray. Additionally, fans are curious about Christian Convery's character, Oliver, and his rapid aging. Here's a detailed look at the key new characters expected to make an impact in Season 3.
Warning: Some basic plot spoilers for the Invincible comic ahead!
Jonathan Banks as Conquest
Jonathan Banks, renowned for his role in Breaking Bad, is set to join Invincible: Season 3, though his character remains undisclosed by Prime Video. Given Banks' knack for portraying tough, battle-hardened characters, it's highly likely he will voice Conquest, a formidable Viltrumite villain introduced in Invincible #61 in 2009. Conquest, known for his strength and battle scars, arrives on Earth with an ultimatum from the Viltrumite Empire: Invincible must conquer his homeworld, or Conquest will do it himself, leading to a brutal confrontation.
Season 2 laid the groundwork for this epic battle, with Mark Grayson accepting his father's legacy as Earth's potential conqueror. In Season 3, we can expect Mark to face off against Conquest in a desperate struggle for survival and the fate of Earth.

Doug Bradley's Role in Invincible Season 3
While Jonathan Banks is a strong candidate for Conquest, the role of Doug Bradley, famous for his portrayal of Pinhead in the Hellraiser series, remains a mystery. Given his iconic voice, Bradley is likely to play another villain. Two possibilities stand out: Dinosaurus, introduced in Invincible #68, and Grand Regent Thragg, a pivotal antagonist in the series.
Dinosaurus, with his mission to heal the world from human civilization's toxic effects, could benefit from Bradley's commanding voice. Alternatively, Bradley might voice Thragg, the ruler of the Viltrumite Empire, whose immense power and combat skills make him a formidable foe. While Thragg might not appear prominently in Season 3, his introduction could set the stage for future conflicts.


Christian Convery's Oliver Grayson
Introduced in Season 2, Oliver Grayson, Mark's half-brother, is a unique hybrid of Thraxan and Viltrumite heritage. His accelerated aging becomes a central plot point in Season 3, with Oliver appearing as a preteen despite being only months old. Christian Convery takes on the role, showcasing Oliver's rapid development as he begins to walk, talk, and even fly.
Oliver's powers manifest much earlier than Mark's, and he adopts the codename Kid Omni-Man, eager to follow in his father and brother's heroic footsteps. As Mark navigates his own path as a hero, he must also guide and protect his younger brother, adding a new layer of complexity to his journey.

In other Invincible news, the franchise is set to expand with the new prequel spinoff Invincible: Battle Beast, one of IGN's most anticipated new comics of 2025.
