With Invincible Season 3 on the horizon, Prime Video has unveiled a stellar new voice cast. Aaron Paul as Powerplex, John DiMaggio as The Elephant, and Simu Liu as Multi-Paul are exciting additions. However, the most intriguing announcements are shrouded in mystery: Jonathan Banks (Breaking Bad) and Doug Bradley (Hellraiser) have joined the cast, but their roles remain undisclosed.

Prime Video's secrecy likely aims to avoid spoiling major Season 3 plot points. Speculation is rife about which characters Banks and Bradley will portray. And what about Christian Convery's Oliver? His rapid aging and emergence as a potential sidekick are significant developments. Let's delve into the most anticipated new characters.

Warning: Minor comic book spoilers ahead!

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

Jonathan Banks' casting is a significant event. His expertise in portraying hardened, grizzled killers strongly suggests a villainous role. The most likely candidate? Conquest. Introduced in Invincible #61, Conquest is a Viltrumite—a powerful warrior even by his species' standards.

Conquest arrives after a devastating conflict, issuing an ultimatum: Invincible conquers his homeworld or faces death. This sets up a brutal battle, testing Mark Grayson's skills against a seasoned Viltrumite. Season 2 hinted at this confrontation, making it a likely Season 3 focal point. Mark’s inexperience against veteran Viltrumites will be put to the ultimate test.

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 again points towards a villain. Two possibilities stand out:

First, Dinosaurus (Invincible #68). Unlike Conquest, Dinosaurus aims to heal the world from humanity's destructive impact. His somewhat cartoonish appearance belies a compelling motivation, and Bradley's voice could add significant gravitas.

Alternatively, Grand Regent Thragg (Invincible #11) is a strong contender. The ruler of the Viltrumite Empire, Thragg is a formidable and ancient warrior, a key antagonist in the comics. Bradley's charisma and menace would perfectly embody this powerful villain. While a full Thragg appearance might be saved for later, a tease seems highly likely.

Christian Convery's Oliver Grayson: A New Sidekick

Season 2 introduced Oliver, Mark's half-brother. Half-Thraxan, half-Viltrumite, his rapid aging is a key plot point for Season 3. Christian Convery's casting reflects Oliver's accelerated growth, transforming him from toddler to preteen. He’s already displaying powers, surpassing Mark's early development.

Oliver's powers and the "Kid Omni-Man" codename suggest a significant role. He's a potential ally, but also a source of concern for Mark, adding another layer of responsibility to his heroics.
