Pagliaccio

Pagliaccio is a "Terminal" program of the Heart Primeval, deployed to act as the Primevals' intelligence-gathering program and "field commander." She assumes the form of hovering, doll-like pierrot, standing cruciform atop a balancing ball which can open and hold her collapsed humanoid form for high-speed travel. Speaks in a cold, droning monotone with barely noticeable traces of emotion. She appears after Pasder is destroyed, absorbing the remaining fragment him into herself when she arrives in Earth orbit, making her the recipient of his dormant program and all of his knowledge.

She is "retrieved" by the core of Heart Primeval upon GGG's arrival at Jupiter, in preparation for Z-Master Fusion as she ultimately becomes part of the Z-Master itself. She is never directly identified (or even noticed) by any entity other than the Primevals themselves (who pay little attention to her outside of her orders). Her name means "Clown" in Italian.
