In his first appearance, Aeon had taken on the form of a humanoid lizard-like creature with yellow scales and red and black highlights. His only clothing was an armored breastplate, arm bands and shin guards. Upon returning in Soulcalibur III, his appearance transformed drastically, resembling an iguana-like creature with feathers growing out of various parts of his body, including his tail bangs of hair on the sides of his head and his scales have changed to a cyan color. He had long since discarded his Greek armor in favor of war-oriented gear. By this time, while he had retained his general fighting style, he replaced his holy weapons with another shield and an axe.
