cast.
The Core Cast: The Grayson Family and Allies

The emotional weight of the series rests on the performances of the lead cast, who must balance domestic drama with high-stakes superhero violence.
- Mark Grayson / Invincible: Voiced by Steven Yeun. Yeun brings a relatable, youthful vulnerability to Mark as he navigates the trauma of his father’s true nature.

- Debbie Grayson: Voiced by Sandra Oh. Oh captures the strength and heartbreak of a mother discovering her husband’s devastating secrets.
- Samantha Wilkins / Atom Eve: Voiced by Gillian Jacobs. Jacobs balances Eve’s independence and power with her growing romantic connection to Mark.

- Allen the Alien: Voiced by Seth Rogen. Rogen provides the distinct, comedic voice for the Unopan scout who becomes an unlikely ally to Mark.
- Cecil Stedman: Voiced by Walton Goggins. Goggins voices the pragmatic, morally grey director of the Global Agency.
