As Invincible: Season 3 gears up for its premiere, Prime Video has unveiled an exciting lineup of new voice actors set to join the acclaimed 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 enigmatic additions to the cast are Jonathan Banks and Doug Bradley, whose roles remain shrouded in mystery, hinting at significant plot developments to come.

Prime Video's decision to keep Banks and Bradley's characters under wraps suggests that Season 3 will introduce pivotal new elements to the storyline. Speculation is rife about which characters from the Invincible comic universe they might portray. Additionally, the rapid aging of Christian Convery's character, Oliver Grayson, raises intriguing questions about his role and impact on the series moving forward. Let's delve into the details of these crucial new characters expected to appear in the upcoming season.

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 warrior introduced in Invincible #61. Conquest is known for his strength and battle scars, embodying the essence of a Viltrumite soldier.

Conquest arrives on Earth with a dire ultimatum from the Viltrumite Empire: Mark Grayson, aka Invincible, must conquer his home planet, or face death at Conquest's hands. This sets the stage for one of the most intense battles in Mark's life. Season 2 laid the groundwork for this confrontation, and Season 3 is poised to deliver on this promise, challenging Mark to stand alone against a seasoned Viltrumite warrior.

Who Is Doug Bradley Playing in Invincible Season 3?

While Banks is a strong candidate for Conquest, Doug Bradley's role remains a tantalizing mystery. Known for his chilling portrayal of Pinhead in the Hellraiser series, Bradley is expected to voice another villain. Two likely candidates are Dinosaurus and Grand Regent Thragg.

Dinosaurus, introduced in Invincible #68, is a unique 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 distinctive voice, adding depth to this complex character.

Alternatively, Bradley could be voicing Grand Regent Thragg, the ultimate antagonist of the Invincible saga. Thragg, a millennia-old Viltrumite and ruler of the empire, is a formidable foe whose introduction in the series is long overdue. Bradley's commanding presence would be perfect for this role, setting the stage for Mark's final battle.

Christian Convery’s Oliver Grayson -----------------------------------

Season 2 introduced Oliver Grayson, Mark's half-brother, who ages at an accelerated rate due to his hybrid Thraxan-Viltrumite heritage. By Season 3, Oliver, now portrayed by Christian Convery, will appear as a preteen, showcasing his rapid growth and emerging powers.

Oliver's quick development means he's already displaying abilities that took Mark years to master. In Season 3, Oliver will adopt the moniker Kid Omni-Man and join Invincible in battle, adding a new dynamic to the series. Mark's role as a mentor to his younger brother will be central to the narrative, as he navigates the challenges of being a hero while protecting his family.
