His printed head is the same used for Attila, Hackler, Howla, Ming, Spyder, and Yokai. His torso was also used for Ghurka, and his face mask and hat are shared with Ghoultar, Ghurka, Pitch, and Wail. Cyrus also uses the same legs as the other Ghost Warriors with legs, with the exception of Morro, Bansha, Soul Archer, and Wrayth.
