Pagliaccio is a program of Heart Primeval that serves as its intelligence-gathering and field commander. She takes on the form of a hovering, doll-like pierrot with a cruciform shape atop a balancing ball for high-speed travel. Her voice is cold and monotonous with barely perceptible traces of emotion. After Pasder's destruction, she absorbs his remaining fragment into herself, becoming the recipient of all his knowledge. She is retrieved by Heart Primeval in preparation for Z-Master Fusion, ultimately becoming part of it. Pagliaccio remains unnoticed and unidentified by any other entity except the Primevals themselves, who pay little attention to her outside of orders. Her name means "Clown" in Italian.
