What is the plot synopsis for Invincible season 3 - what happened in season 2?

Invincible season three picks up where season two ended, with Mark feeling the emotional toll of his fight with Angstrom Levy. In a shocking moment, he lost control and beat his enemy almost to death, proving that there only a fine line between him and his father Nolan (Omni-Man).

In season three, Mark will be in training to become even stronger and faster. Cecil has been putting him through his paces in a new fitness regime, but the new trailer suggests that his relationship with the director of the GDA could turn sour.

Mark is also attempting to juggle everything that comes with being a teenage superhero, all while dealing with bonding with his growing baby brother Oliver and his break-up from Amber at the end of season two. The break-up saw him grow closer to Eve, but will Mark make a move in season three?

Meanwhile, Mark’s dad Omni-Man looks set to join with Allen the Alien to plot their escape from Viltrumite jail. It comes after Allen approached him at the end of season two to encourage him to work with the Guardians of the Globe against his own Viltrumite race to thwart their threat to Earth.
