Prime Video's 'Invincible' Season 4 Lands Rotten Tomatoes Score

Invincible Season 4 is set to premiere on Prime Video on Mar. 18, 2026, with the first three episodes releasing that day and weekly Wednesday drops through late April. Fans are particularly eager for the Viltrumite War arc, widely regarded as the series' emotional center and the definitive end of Mark Grayson’s coming-of-age.

Early reviews have given the season a 100% critics' score on Rotten Tomatoes, based on 10 reviews so far. That percentage could change as more critics weigh in, but it continues the show's perfect run after Seasons 2 and 3; Season 1 remains at a 98% "Certified Fresh" rating.

Critics praise a darker tone, cinematic animation and a nuanced exploration of the Viltrumite Empire.
