The Invincible Boys

The Invincible Boys (also called Invincible vs. The Boys) is an adult-animated superhero TV special movie, airing exclusively on Amazon Prime Video. The film is a crossover between the 2019 TV series The Boys and the 2021 animated series Invincible (both also airing on Amazon Prime Video).

The film stars an ensemble cast of actors and voice actors reprising their roles from both series, including Steven Yeun as Mark Grayson / Invincible and Karl Urban as Billy Butcher.

Premise
Set after the events of Invincible Season 1 and The Boys Season 2, a hyper-dimensional relic begins linking their both dimensions with one another, putting Mark Grayson / Invincible in conflict against the Boys, with Billy Butcher believing that the Guardians of the Globe are invaders (and more false heroes like the Seven), while the Seven try to form a new alliance with the Guardians of the Globe. But when Omni-Man and Homelander clash against each other for control over the relic, resulting in battles which threaten mankind, Invincible and the Boys must put aside their differences, work together to stop their Earths' impending doom, and fend-off a common foe who is orchestrating the issuing chaos using the Global Defense Agency's Reanimen technology and what remained from Stormfront.
