Invincible Season 4 is expected to be released in early 2026, most likely around March or April. This estimate is based on the release patterns of previous seasons and official announcements. Voice acting for the season has already been completed, and the season will include major plotlines such as the Viltrumite War and the introduction of the character Thragg, a key antagonist from the comics. The season is anticipated to have around eight episodes, similar to earlier seasons, and will continue the story with returning cast members. The show was officially renewed for Season 4 in July 2024.
