It is produced by Skybound Entertainment, Wind Sun Sky Entertainment, Point Grey Pictures, and Amazon MGM Studios. The series revolves around Mark Grayson, a teenage human-alien hybrid, who becomes a crime-fighting superhero known as "Invincible" under the guidance of his father, Nolan Grayson / Omni-Man, the most powerful superhero on the planet. As he adjusts to his newfound powers, Mark struggles to balance his personal life with his superhero duties and is forced to prove that he can live up to his father, unaware of a conspiracy that threatens the world and leading him to question the true nature of his role. Steven Yeun stars in the series as Mark Grayson / Invincible alongside J. K. Simmons and Sandra Oh as Mark's father and mother, Nolan Grayson / Omni-Man and Debbie Grayson, respectively, while the remaining cast members have recurring roles.

*Invincible* premiered its eight-episode first season across March and April 2021, after which Amazon renewed the series for a second and third season. A prequel special, "Invincible: Atom Eve" was released in July 2023. The eight-episode second second was divided into two parts, first released in November 2023, then across March and April 2024. The eight-episode third season was released between February and March 2025. The fourth season premiered on March 18, 2026. A fifth season has also been announced ahead of its release.

The series had received widespread critical acclaim, with praises for its animation, action sequences, story, voice performances (particularly Yeun, Oh, and Simmons), faithfulness to the comics, and emotional weight. It has been nominated for two Primetime Emmy Awards, two Annie Awards and the Critics' Choice Television Award for Best Animated Series.

## Premise
Mark Grayson is a seemingly typical teenager whose father, Nolan Grayson, also known as "Omni-Man", is the most powerful superhero on Earth. Shortly after he turns 17, Mark begins to develop his own powers and learns how to wield them in order to fight injustice as "Invincible", with help from his father, who actually turns out to not be as heroic as he thought, as he hides a dark secret, which begins to slip when he brutally murders the members of the world's greatest superhero team, the Guardians of the Globe.
