The Boys spinoff has added three more to the cast: Shane Paul McGhie, Maddie Phillips, and Aimee Carrero.

The actors will be playing young superheroes at the only college for young adult superheroes run by Vought International. They join previously announced actors Jaz Sinclair and Lizzie Broadway.

The untitled series has been described as “an irreverent, R-rated series that explores the lives of hormonal, competitive Supes as they put their physical, sexual, and moral boundaries to the test, competing for the best contracts in the best cities. Part college show, part Hunger Games — with all the heart, satire and raunch of The Boys.”

Amazon announced the project was in development in September.

The Boys, which is based on the best-selling comic by Garth Ennis and Darick Robertson, was renewed by Amazon Prime Video for Season 3 last July before the second season premiered. An after-show called Prime Rewind: Inside The Boys, hosted and executive produced by Aisha Tyler, was also added to the service.
