The beastly Vision Icelus (幻夢・イケロス Genmu Ikerosu?) is the most savage and brutal of the dream gods. He is indeed bestial in appearance, resembling something of a vampire or even a werewolf due to his extremely long fangs, clawed hands and hunchback posture. He is often represented as a smilodon or another sort of beast, for he is the god of nightmares, appearing in the mortals' dreams as a monster or feral beast. He is able to warp space, thus sending his enemies' attacks to themselves, teleporting at will and cutting through space itself. Icelus fights Capricorn El Cid twice, firstly amputating the Saint's right arm, and secondly challenging him in the dream world. After a ferocious battle against the Capricorn Saint, during which he had the advantage, El Cid managed to spot the weak point in his power, using his own blood to find the warps in space. Thus he is defeated, dying beheaded by the Excalibur.
