As the highly anticipated Invincible: Season 3 approaches, Prime Video has unveiled a fresh roster of voice actors set to join the animated series. Among the newcomers are Aaron Paul voicing Powerplex, John DiMaggio as The Elephant, and Simu Liu stepping into the role of Multi-Paul, Dupli-Kate's brother. Yet, the most enigmatic additions to the cast are Jonathan Banks and Doug Bradley, whose characters remain undisclosed, adding an air of mystery and anticipation to the upcoming season.

Prime Video's decision to withhold this information suggests major plot developments on the horizon for Season 3. Speculation is rife about which characters from the Invincible universe Banks and Bradley might portray. Additionally, the role of Christian Convery's Oliver Grayson is stirring curiosity. How is he aging so rapidly, and what impact will he have as Invincible's new sidekick? Let's delve into the details of these key new characters expected to appear this season.

Warning: some basic plot spoilers for the Invincible comic ahead!

Jonathan Banks, renowned for his role in Breaking Bad, is joining Invincible: Season 3, though his character remains a mystery. However, fans have a strong hunch that Banks will voice Conquest, a formidable villain from the Invincible comics who debuted in 2009's Invincible #61. As a Viltrumite like Invincible and Omni-Man, Conquest is a seasoned warrior whose battle scars testify to his prowess.

Conquest arrives on Earth post a catastrophic conflict, delivering an ultimatum from the Viltrumite Empire: Invincible must conquer his home planet or face death at Conquest's hands, triggering a brutal confrontation. Season 2 laid the groundwork for this showdown, showing Mark Grayson accepting his father's mantle as Earth's potential conqueror. In Season 3, fans can expect Mark to face this daunting challenge, despite his youth and inexperience.

Who Is Doug Bradley Playing in Invincible Season 3?

While Banks seems destined for Conquest, speculation swirls around Doug Bradley's role. Famous for portraying Pinhead in the Hellraiser series, Bradley is likely to voice a villain. Two characters from the comics stand out: Dinosaurus, introduced in 2009's Invincible #68, and Grand Regent Thragg, who first appeared in 2004's Invincible #11.

Dinosaurus, with his mission to heal the world from human-induced harm, could be brought to life with Bradley's distinctive voice. This character's radical approach to environmental salvation, including targeting Las Vegas for destruction, adds depth to the Invincible narrative.

Alternatively, Bradley could voice Thragg, the ruler of the Viltrumite Empire and a pivotal antagonist in the series. Thragg's millennia of combat experience and his role in the empire's civil war make him a formidable foe. Bradley's commanding presence would be perfect for this character, whose introduction in the animated series is long overdue.

Introduced in Season 2, Oliver Grayson is Mark's half-brother, born of Nolan's union on Thraxa. His unique heritage as half-Thraxan and half-Viltrumite results in rapid aging and early manifestation of powers. By Season 3, Oliver, now played by Christian Convery, will appear as a preteen, showcasing his ability to walk, talk, and fly.

Oliver's accelerated growth and burgeoning powers will be central to Season 3. He'll adopt the moniker Kid Omni-Man and join Invincible in battle, adding both a new ally and a potential vulnerability to Mark's life. As Invincible, Mark must navigate his role as a hero while guiding his younger brother, a task made more challenging by the ever-present threat to his loved ones.
