Season 3 of Invincible: Key New Characters Revealed

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: Mark Grayson 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 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 Banks is a strong candidate for Conquest, Doug Bradley, famous for his portrayal of Pinhead in the Hellraiser series, is also joining the cast. Bradley's distinctive voice suggests he might be voicing a villain, with two likely candidates: Dinosaurus or Grand Regent Thragg.

Dinosaurus, introduced in Invincible #68, is a villain with a mission to heal the world from human-induced damage. His plan to destroy Las Vegas as a symbol of human excess could be brought to life with Bradley's commanding voice. Alternatively, Bradley could be voicing Grand Regent Thragg, the ultimate antagonist of the Invincible saga. Thragg, a powerful Viltrumite ruler, is a key figure in the empire's history and a formidable foe for Mark Grayson.

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 of the rapidly maturing Oliver, who begins to exhibit his powers much earlier than Mark did.

In Season 3, Oliver will adopt the codename Kid Omni-Man and join Invincible in battle, adding a new dynamic to the series. Mark must now navigate his role as a hero while mentoring his powerful younger brother, whose presence adds both strength and vulnerability to their family.
