The harmonious shapes of Shape City are suddenly attacked by a band of discolored and disfigured shapes called the Korruptids, led by the evil Emperor Clyde Dez Kope, ruler of the Korruptids. By using Clyde’s Dark Prism Powers, he has turned the citizens of Shape City into misshapen, oddly colored and glitched shapes. They follow Clyde as his entourage of evil as they travel through different areas corrupting solid colored shapes to enlist in his army, in hopes of turning all the world's shapes into his corrupted image.
