With Invincible Season 3 on the horizon, Prime Video has unveiled a stellar new voice cast. Joining the fray 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 are shrouded in mystery: Breaking Bad's Jonathan Banks and Hellraiser's Doug Bradley are onboard, but their roles remain undisclosed.

Prime Video's secrecy likely aims to preserve some major Season 3 plot twists. But speculation is rampant! Which Invincible characters could Banks and Bradley be portraying? And what about Christian Convery's Oliver? His rapid aging is a significant development, especially now that Invincible has a new sidekick. Let's delve into the most anticipated new characters.

Warning: Minor comic book spoilers ahead!

While Prime Video keeps mum, Jonathan Banks' casting strongly suggests a specific villain. His expertise in portraying hardened killers points towards Conquest, introduced in Invincible #61. A Viltrumite of immense power, Conquest arrives after a devastating Earth conflict, presenting Invincible with an ultimatum: conquer his homeworld or face death.

Season 2 laid the groundwork for this confrontation, leaving Mark burdened with his father's legacy. Season 3 will likely see Mark's desperate struggle against Conquest, a seasoned Viltrumite warrior. This battle will test Mark's youth and inexperience, forcing him to find a way to survive and prevent Earth's enslavement.

Who Is Doug Bradley Playing?

While Banks seems a perfect fit for Conquest, Bradley's role remains a mystery. Known for portraying Pinhead, his casting likely signifies another villain. Two possibilities emerge: Dinosaurus, from Invincible #68, or Grand Regent Thragg, from Invincible #11.

Dinosaurus, a villain with surprisingly altruistic motivations, aims to heal the world from humanity's destructive impact. Bradley's voice could add depth to this seemingly cartoonish character, whose actions stem from a warped sense of environmentalism.

Alternatively, Thragg, the Viltrumite Empire's ruler, is a formidable antagonist. His introduction in the comics is a major event. Bradley's charisma and menace would perfectly capture Thragg's power and menace. While a full Thragg appearance might be reserved for later seasons, a tease in Season 3 is highly plausible.

Christian Convery's Oliver Grayson

Season 2 introduced Oliver, Mark's half-brother, a half-Thraxan, half-Viltrumite hybrid. His accelerated aging is a key plot point for Season 3, with Christian Convery taking over the role. Oliver's rapid development means he'll be walking, talking, and flying.

Oliver's powers are already emerging, surpassing Mark's developmental trajectory. He'll adopt the codename Kid Omni-Man, becoming both a powerful ally and a potential liability for Invincible. Mark's responsibility for his brother adds another layer of complexity to his heroic journey.
