Similar to how Invincible season 3 premiered its episodes, the first three will serve as the introduction of Mark Grayson's latest dilemmas before the following stories unfold every Wednesday on the streamer.

What Fans Can Expect From Invincible Season 4 Part 2
Season 4 sees Omni Man return to Earth with Allen the Alien to ask his son to join him in the war against the Viltrumites before they destroy the Earth for good.
Mark, on the other hand, has become even more determined to protect humanity from Viltrumites, especially after his near-death experience from fighting the bloodthirsty villain, Conquest. Season 4 doesn't go any easier on Mark as he's about to face a tougher opponent, Grand Regent Thragg.
The stakes have never been higher for the Grayson family. As the world recovers from the catastrophic "Invincible War", Mark is forced to balance his humanity with the brutality required to stop a galactic invasion. Could Nolan truly recruit his son and gain his trust back to stop the Viltrumite Empire from taking over?
