Adam resembled a massive muscular man with medium length hair and well defined features. His dark hair hung at a medium length. Shortly after forming he created armour for himself out of the ruins of Sodom, later after his death and subsequent resurrection his armour changed and became more futuristic, and applied large cannons to his solders.
Adam was a brash and cruel warrior, loyal to his creators and has no care or well being for humanity, killing them in ease. He did have at least some pre-established relationship with Eve, who vowed vengeance in his death.
- The armor Adam wears resembles that of Ares, a Mechanical God from the Z Mazinger manga, a 1998 Go Nagai work derived from Mazinger Z.
