Invincible Season 4 release date has been confirmed in the trailer

The trailer of Invincible Season 4 came out last week. It marks the reunion of 'Mark Grayson' and his father, 'Omni-Man,' as they team up to face another threat. The release date was confirmed as March 18, 2026, by Amazon Prime Video towards the end of the trailer on January 22, 2026. Users of Prime Video with a subscription to the streaming platform would be able to access the new season of the series. Prime Video is already available in more than 240 countries and territories.

Robert Kirkman has hinted at more brutality in Invincible Season 4

In a recent interview, the show's creator, Robert Kirkman, said that the brutality in Invincible Season 4 won’t be the same as viewers have witnessed in the previous three installments. Robert said that the brutality is going to have an emotional touch, which will also “catch people off guard.” Robert stated in the interview that the basic aim is to ensure that the spectacle is reciprocal and emerging from the emotional angle included in the main storyline.

Talking about the main plot of Season 4, the world is recovering from the destruction created due to the fight between 'Mark Grayson' and 'Conquest.' Season 3 ended with 'Mark' making a promise that he would do anything to save his family if they were threatened by anyone. 'Mark Grayson' remains committed to the promise he made, bringing him face-to-face with another threat that might change the fate of humanity.

Conquest is reported to be an important part of the show this time. Furthermore, Robert Kirkman has said in an interview that Season 4 would feature Mark going on a journey to find his true identity, and this is one of the main highlights of his storyline as he enters adulthood.
