As the third season debuted back in February 2025, the new season is arriving a little just over one year after the third instalment, with the animated superhero series significantly speeding up its production.

This follows the comments of Invincible creator Robert Kirkman that the team are working incredibly hard to avoid the two year gap fans experienced between seasons 1 and 2.

"I can’t guarantee that we’ll be coming back in early February every single year, but I can say that is the goal," the writer commented in an interview with Discussing Film.

"We’re working at a breakneck pace behind the scenes with Shaun O’Neill and Dan Duncan and the entire team to keep this factory moving and keep this show in production so that we can come out in a fairly regular clip."

Invincible season 4 is available to stream on Prime Video.
