With the much-anticipated release of Invincible: Season 3 on the horizon, Prime Video has announced an exciting lineup of new voice actors joining the series. Among them are Aaron Paul as Powerplex, John DiMaggio as The Elephant, and Simu Liu as Multi-Paul, Dupli-Kate's brother. However, the most enigmatic additions to the cast are Jonathan Banks and Doug Bradley, whose roles remain undisclosed, sparking intense speculation and excitement among fans.

Prime Video's decision to keep these roles under wraps suggests significant plot developments are in store for Season 3. This secrecy has led to speculation about which characters Banks and Bradley might portray, and what their involvement could mean for the storyline. Additionally, the introduction of Christian Convery as Oliver Grayson raises questions about his rapid aging and his role as Invincible's new sidekick. Here's an in-depth look at the key new characters expected to appear in the upcoming season.

Warning: some basic plot spoilers for the Invincible comic ahead!

Jonathan Banks, known for his role in Breaking Bad, is joining the cast of Invincible: Season 3, though his character has not been officially revealed. Given Banks' reputation for portraying hardened, grizzled characters, it's widely speculated that he will voice Conquest, a formidable Viltrumite warrior introduced in Invincible #61 in 2009.

Conquest is not just any Viltrumite; he's one of the most powerful, bearing the scars of countless battles. He arrives on Earth with a chilling ultimatum from the Viltrumite Empire: Invincible must conquer his home planet, or Conquest will do it himself, killing Invincible in the process. This sets the stage for a brutal and intense confrontation, which fans can expect to see unfold in Season 3. The groundwork for this epic battle was laid in Season 2, where Mark Grayson, aka Invincible, reluctantly accepted his father's role as Earth's future conqueror. Now, still young and inexperienced, Mark must face Conquest in a battle that could determine the fate of his world.

Who Is Doug Bradley Playing in Invincible Season 3?

Doug Bradley, famous for his role as Pinhead in the Hellraiser series, is another mysterious addition to the cast. Speculation suggests he might voice one of two significant villains from the Invincible comics.

The first possibility is Dinosaurus, introduced in Invincible #68 in 2009. Unlike Conquest, Dinosaurus has a unique motivation: he aims to heal the world from the destructive impact of human civilization. His plans include drastic actions like destroying Las Vegas, which he views as a blight on the environment. Bradley's distinctive voice could add depth and intensity to this complex character, whose goals, while radical, are driven by a desire for the greater good.

Alternatively, Bradley could be voicing Grand Regent Thragg, the ultimate antagonist of the Invincible saga. Introduced in Invincible #11 in 2004, Thragg is the ruler of the Viltrumite Empire, a seasoned warrior with thousands of years of combat experience. His eventual confrontation with Invincible is a pivotal moment in the series. Bradley's commanding presence and menacing tone make him a perfect fit for this iconic villain, and fans might get a tease of his character in Season 3, setting the stage for future conflicts.

Introduced in Season 2, Oliver Grayson, Mark's younger half-brother, is set to play a significant role in Season 3. Born on Thraxa to Nolan and a new partner, Oliver's hybrid Thraxan-Viltrumite heritage results in rapid aging. By Season 3, despite being only a few months old, Oliver will appear as a preteen, a development that Christian Convery will bring to life.

Oliver's accelerated growth and emerging powers will be central to the season's plot. Unlike Mark, who developed his abilities gradually, Oliver's powers manifest much earlier. He will don a costume and adopt the codename Kid Omni-Man, joining Invincible in battle. This new dynamic adds layers to Mark's journey as he navigates his role as a hero while mentoring his younger brother. Oliver's presence not only provides Mark with a powerful ally but also introduces new risks, as Mark fears for his family's safety amidst his superhero duties.
