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

Author: Christopher Mar 18,2025

With Invincible Season 3 on the horizon, Prime Video has 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 involves the enigmatic casting of Jonathan Banks (Breaking Bad) and Doug Bradley (Hellraiser), whose roles remain shrouded in secrecy. Prime Video is clearly keeping these reveals under wraps to avoid spoiling major Season 3 plot points.

Speculating on Banks and Bradley's characters, and the rapid aging of Christian Convery's Oliver, opens up exciting possibilities. Let's delve into the most significant new characters expected this season.

Warning: Minor comic book spoilers ahead!

PlayJonathan Banks as Conquest? --------------------------

Jonathan Banks' casting is a significant event. His expertise in portraying hardened, grizzled killers strongly suggests a villainous role. The prime candidate, based on the comics, is Conquest. Debuting in Invincible #61 (2009), Conquest is a Viltrumite—a powerful warrior even by Viltrumite standards, bearing the marks of countless battles.

Conquest arrives after a devastating conflict on Earth, delivering an ultimatum from the Viltrumite Empire: Invincible must conquer his homeworld, or face Conquest's wrath. This sets up a brutal showdown—a desperate battle for Mark Grayson's survival.

Season 2 hinted at this confrontation, leaving Mark grappling with his father's legacy. Season 3 likely delivers on this, pitting Mark against Conquest. Given Mark's relative inexperience, this will be a formidable challenge.

Doug Bradley's Mysterious Role

While Banks seems a perfect fit for Conquest, Bradley's role remains a mystery. Known for his portrayal of Pinhead in the Hellraiser films, his casting suggests another villain.

Two possibilities emerge: Dinosaurus (Invincible #68, 2009), a villain whose motivations differ significantly from Conquest. Dinosaurus aims to heal the world from humanity's destructive impact, targeting Las Vegas as a symbol of this destruction. Bradley's voice could add depth to this somewhat cartoonish character.

Alternatively, it could be Grand Regent Thragg (Invincible #11, 2004), the series' main antagonist. His absence from the animated series thus far makes his appearance overdue.

Thragg, the Viltrumite Empire's ruler, is incredibly powerful, thousands of years old, and a key figure in the empire's civil war. Bradley's charisma and menace would perfectly embody this formidable villain. Even a brief appearance would significantly impact the series.

Christian Convery's Accelerated 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. He'll transition from toddler to preteen, necessitating Convery's casting. Oliver's powers are already manifesting, far surpassing Mark's early development.

Oliver adopts the codename Kid Omni-Man, becoming a powerful ally but also a potential liability for Mark. This adds a new layer of complexity to Mark's role as Invincible.
