Adam was an angel with a human appearance. Most of the time, he wore a mask that appeared similar to other Exorcists, though with normal-looking eyes and golden facial expressions. The mask also held a pair of horns similar to an Exorcist, albeit longer, smoother, and with a golden ornamental attachment on the tips. Under his mask, he is revealed to be a fair-skinned angel with golden-yellow eyes that have dark bags underneath, a stubble-beard on his chin, and slightly messy, short cedar-brown.
