The Stand only made a temporary appearance in order for Dio to evolve it into Made in Heaven Ultimate Requiem during his battle with Kars.
C-Moon Ultimate Requiem resembles the original C-Moon which was used by Enrico Pucci. It has three heads, along with three pairs of arms similar to the demigod Asura. Like Whitesnake Ultimate, the middle face is the original. The left head has enlarged lips that stick out, and the right head has skeletal teeth which appear to be sharp. After being stabbed by the arrow, it fused within the Stand, and added on to its appearance. The arrows appear and stick out on the back of the Stands arms. Like C-Moon, the Stand has spikes sticking out near its collarbone, and wears a belt made out of a fur-like texture. It has patterns right beneath its chest, engraved with the word "K△RZ" all over it.
