The series, based on the comic book of the same name, follows a group of vigilantes who are trying to take down corrupt superheroes abusing their powers. It debuted in 2019 and has since inspired several spinoffs set in the same universe, including "Gen V," which premiered in September; "Diabolical," an animated series that came out in March 2022; and "Seven on 7," a web series in July 2021.

While Season 4 of "The Boys" has many previous cast members reprising their roles, this season has a slate of new faces, including Jeffrey Dean Morgan, Rob Benedict and Eliot Knight, according to Prime.

Here's a list of all the actors in "The Boys" and the character they play.
