As the eagerly anticipated debut of Invincible: Season 3 approaches, Prime Video has unveiled an exciting new lineup of voice actors set to join the series. This season will feature Aaron Paul voicing Powerplex, John DiMaggio as The Elephant, and Simu Liu lending his voice to Dupli-Kate's brother, Multi-Paul. However, the most intriguing additions to the cast are Jonathan Banks from Breaking Bad and Doug Bradley, known for his role in Hellraiser, whose characters remain a mystery. Prime Video's decision to keep these roles under wraps suggests that significant plot developments are on the horizon for Season 3.
Speculation is rife about the characters Banks and Bradley might portray. Additionally, fans are curious about Christian Convery's character, Oliver, and his rapid aging, as well as his new role as Invincible's sidekick. Here’s a detailed look at the key new characters we expect to see this season.
Warning: some basic plot spoilers for the Invincible comic ahead!
Jonathan Banks as Conquest
Jonathan Banks, renowned for his role in Breaking Bad, is set to join Invincible: Season 3, though his character remains undisclosed by Prime Video. However, fans speculate that Banks is likely to voice Conquest, a formidable Viltrumite villain who debuted in Invincible #61 in 2009. Known for his grizzled, hardened persona, Banks is a perfect fit for Conquest, a warrior renowned for his strength and battle scars.
Conquest arrives on Earth with an ultimatum from the Viltrumite Empire: Invincible must conquer his homeworld or face death at Conquest's hands. This sets the stage for a brutal confrontation, a theme already teased in Season 2 when Mark Grayson accepts his father's role as Earth's future conqueror. In Season 3, Mark's inexperience will be tested against this seasoned Viltrumite, forcing him into a desperate fight for survival.

Who Is Doug Bradley Playing in Invincible Season 3?
While Banks is expected to voice Conquest, the role of Doug Bradley, famous for portraying Pinhead in the Hellraiser series, remains a subject of speculation. Two characters from the comic series stand out as potential fits for Bradley's unique voice: Dinosaurus and Grand Regent Thragg.
Dinosaurus, introduced in Invincible #68, aims to heal the planet from human-caused damage, a stark contrast to Conquest's brutality. His plan to destroy Las Vegas as a symbol of human excess could be brought to life with Bradley's distinctive voice, adding depth to this complex villain.

Alternatively, Bradley could voice Grand Regent Thragg, the true main antagonist of the Invincible saga. First appearing in Invincible #11 in 2004, Thragg is a powerful Viltrumite ruler, trained in countless combat forms and a survivor of the empire's civil war. Bradley's commanding presence would be ideal for this role, potentially setting up Thragg as Mark Grayson's ultimate adversary in future seasons.

Christian Convery’s Oliver Grayson
Season 2 introduced Oliver Grayson, Mark's younger half-brother, born to Nolan on Thraxa. Oliver's unique heritage as half-Thraxan and half-Viltrumite results in accelerated aging, a key plot point in Season 3. By this season, Oliver, now portrayed by Christian Convery, will appear as a preteen, showcasing his rapid development and emerging powers.
Oliver's accelerated growth allows him to manifest his abilities much earlier than Mark did, and he will adopt the codename Kid Omni-Man, joining Invincible in battle. This new dynamic adds complexity to Mark's journey as he navigates his role as a hero while guiding his powerful yet vulnerable brother. Oliver's presence introduces both a new ally and a potential risk, as Mark grapples with the fear of endangering those he loves.

As Invincible: Season 3 promises to bring new challenges and characters to the forefront, fans eagerly await the unveiling of Jonathan Banks and Doug Bradley's roles. In other news, the Invincible universe expands with the upcoming prequel spinoff Invincible: Battle Beast, which is among IGN's most anticipated new comics of 2025.
