Nicki Minaj unleashes her superpowers in an upcoming episode of Cartoon Network’s animated series “Steven Universe.”

The “Pills N Potions” rapper lends her voice to Sugilite, the mighty and powerful fusion of Garnet and Amethyst, two of the show’s magically powered “gems” who help protect the world.

TV Guide has a sneak peek from the episode, which was screened at Comic-Con in San Diego last week.

The episode also features Estelle, who voices the warrior Garnet.

This is not Nicki’s first animated feature. She previously voiced a woolly mammoth named Hailey in the 2012 movie Ice Age: Continental Drift and played an animated version of herself on Fox’s “The Cleveland Show.”

The full episode, “Coach Steven,” premieres August 21 at 6:30 p.m. on Cartoon Network.
