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 news comes in the form of two enigmatic castings: Jonathan Banks (Breaking Bad) and Doug Bradley (Hellraiser), whose roles remain shrouded in mystery.

Prime Video's secrecy likely aims to preserve major Season 3 plot twists. But speculation is rampant. Who could Banks and Bradley be playing? And what about Christian Convery's rapidly aging Oliver? Let's delve into the most anticipated new characters.

Warning: Minor comic book spoilers ahead!

Jonathan Banks as Conquest? --------------------------

Jonathan Banks's casting is exciting, but his character remains undisclosed. His expertise in portraying hardened villains strongly suggests a specific comic book antagonist: Conquest. Debuting in Invincible #61, Conquest is a Viltrumite, even more powerful than many of his kind, bearing the marks of countless battles.

Conquest arrives after a devastating Earth conflict, presenting an ultimatum to Invincible: conquer his homeworld or face death. This sets the stage for one of Mark Grayson's most brutal battles. Season 2 hinted at this confrontation, leaving Mark to grapple with his father's legacy. Season 3 will likely see Mark's desperate fight against a far more experienced Viltrumite warrior.

Doug Bradley's Invincible Role

While Banks seems a perfect fit for Conquest, Bradley's role remains a mystery. Known for portraying Pinhead, his casting suggests another villain. Two prominent candidates emerge based on the comic's timeline.

First is Dinosaurus (Invincible #68), a villain whose motivations differ greatly from Conquest. Dinosaurus aims to heal the Earth from humanity's destructive impact, viewing Las Vegas as a prime target. Bradley's voice could lend gravity to this seemingly cartoonish character, whose actions stem from a twisted sense of environmentalism.

Alternatively, Grand Regent Thragg (Invincible #11), the main antagonist of the comic series, is a strong contender. His absence from the animated series so far makes his appearance overdue.

Thragg, the Viltrumite Empire's ruler, is incredibly powerful, thousands of years old, and a key figure in a past civil war. Bradley's charisma and menace would perfectly embody this formidable villain. Even a brief tease of Thragg in Season 3 would be significant, foreshadowing Mark's ultimate adversary.

Christian Convery as 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, requiring Christian Convery to take over the role. Oliver's rapid growth means he'll appear as a preteen, already exhibiting powers far exceeding Mark's at a similar age.

Oliver's powers, combined with his desire to emulate his father and brother, will make him a significant player. He adopts the codename Kid Omni-Man, adding a new dynamic to the series, both as a powerful ally and a potential vulnerability for Mark.
