Invincible: The Most Important New Characters to Expect in Season 3

With Invincible Season 3 on the horizon, Prime Video unveiled a stellar voice cast addition. Aaron Paul as Powerplex, John DiMaggio as The Elephant, and Simu Liu as Multi-Paul are exciting additions. However, the most intriguing reveals are shrouded in mystery: Jonathan Banks (Breaking Bad) and Doug Bradley (Hellraiser) join the cast, their roles remaining undisclosed. Prime Video's secrecy likely aims to preserve major Season 3 plot twists.

Speculation runs rampant: who could Banks and Bradley portray? And what's the story behind Christian Convery's rapidly aging Oliver? His accelerated growth promises significant plot developments, especially with Invincible gaining a new sidekick. Let's delve into the most anticipated new characters.

Warning: Minor comic book spoilers ahead!

Jonathan Banks' casting is exciting, though his character remains a secret. His talent for portraying hardened killers strongly suggests a villainous role. Conquest, introduced in Invincible #61, fits this perfectly. A powerful Viltrumite, Conquest arrives after a devastating Earth conflict, issuing an ultimatum: Invincible conquers his homeworld, or faces death. This sets the stage for a brutal battle.

Season 2 hinted at this confrontation, leaving Mark burdened with his father's legacy. Season 3 will likely see Mark's desperate fight against a seasoned Viltrumite warrior—a challenge he's ill-equipped to handle. His survival and Earth's fate hang in the balance.

Doug Bradley's Mysterious Role

While Banks seems a likely Conquest, Bradley's role is more ambiguous. Known for his portrayal of Pinhead, a villainous role is anticipated. Two candidates emerge: Dinosaurus (Invincible #68) and Grand Regent Thragg (Invincible #11).

Dinosaurus, appearing after Conquest, aims to heal the world from humanity's destructive impact, targeting Las Vegas as a symbol of this damage. Bradley's voice could lend depth to this somewhat cartoonish villain, whose motives resonate with a surprising level of understanding.

Alternatively, Grand Regent Thragg, the series' main antagonist, remains unseen in the animated series. Thragg, the Viltrumite Empire's ruler, is a powerful, ancient warrior who played a key role in the empire's civil war. Bradley's charisma and menace could perfectly embody this formidable villain. Even a brief appearance would tease Mark's ultimate nemesis.

Christian Convery's Oliver Grayson: A New Era

Season 2 introduced Oliver, Mark's half-brother, a half-Thraxan, half-Viltrumite hybrid. His rapid aging, a key plot point for Season 3, sees him transitioning from toddler to preteen, requiring Christian Convery's casting. Oliver displays early signs of his powers, surpassing Mark's development.

Season 3 will see Oliver follow in his father and brother's footsteps, adopting the Kid Omni-Man codename. This presents a significant dynamic: Mark must guide his powerful, yet potentially dangerous, brother, adding another layer of responsibility and risk to his hero's journey.
