The battle for the galaxy reaches a fever pitch as a legendary villain finally makes his move against Earth’s strongest defenders. This upcoming season, Invincible promises a brutal showdown that will test the limits of family loyalty and survival in ways fans have never witnessed before, but when can fans finally watch the animated chaos?

Following a climactic third season that concluded in February 2025, the stakes for humanity have shifted into high gear.

Prime Video officially confirmed that the fourth season of the adult animated hit Invincible will premiere on March 18, 2026. This announcement arrived alongside a trailer that provided a terrifying first glimpse of Lee Pace as the fierce Grand Regent Thragg.

After the intense events of the previous chapters, Mark and Omni-Man are set to reunite to face this unprecedented danger. Thragg leads the Viltrum Empire with a philosophy of absolute strength and cruelty, aiming to restore his people to their former dominance.

The new season will be accessible to viewers in over 240 countries and territories worldwide upon its release. The narrative focuses on a transformed Mark Grayson as he struggles to protect his home from a threat that could end human civilization.

As the world continues to recover from previous catastrophes, the arrival of such a powerful antagonist complicates the path to peace. The production has already secured an early renewal for a fifth season, signaling the streamer’s long-term commitment to the franchise.
