Invincible season 4 review

The fate of the world is at stake in the premiere of Invincible season 4 — and Mark Grayson kills an innocent man. The reasons are complicated, and the choice haunts him for the rest of the season as Earth’s other superheroes debate whether he did the right thing.

The series, which began as an ultra-violent riff on the superhero genre, has spent recent seasons expanding its world rather than focusing on the shocking story that hooked viewers in season 1, when Omni-Man was revealed to be a Viltrumite spy. Season 4 initially bounces between familiar threats — a Martian hive mind, a gangster with rocks for skin, an alien insect invasion — before finally zeroing in on the Nazi-inspired Viltrumite arc that has loomed over the show.

Early episodes show Mark recovering from multiversal variants and a brutal fight with Conquest, while the Guardians of the Globe find their footing and Omni-Man resurfaces intent on redemption.
