Stone Protectors(1993)

Stone Protectors is an animated series set on the distant planet Mythrandir, where Empress Opal guards the Great Crystal, a powerful legendary relic. When the villain Zok threatens to seize it, Opal scatters five of its gems to Earth. The gems crash into a struggling garage band, transforming them into geode-powered rock stars with extraordinary abilities. Suddenly thrust into an unexpected galactic adventure, the newly empowered musicians become Mythrandir's unlikely champions. Now they must travel across the cosmos to protect Opal and her people from Zok's sinister plans. Blending action, humor, and rock-and-roll energy, Stone Protectors follows these reluctant heroes as they discover that saving a planet is just as challenging as making it in the music business.
