Invincible, based on the comic of the same name, follows the story of Mark Grayson, the son of a world-famous superhero, as he learns to control his powers and fight to protect the Earth from supervillains and extraterrestrial threats. The series received mass critical acclaim upon its release for its stunning animation, exciting action, and in parts, its brutality. As Mark begins to learn to control his powers, new threats and mysteries emerge while he attempts to maintain personal relationships. The defining moment in Mark's journey so far came in season one when he took on his father, who was looking to conquer Earth for the Viltrumites.
