Adam was a winner angel with a human appearance. Most of the time, he wore a mask that appeared similar to fellow 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 yellow eyes that have dark bags underneath, a stubble beard on his chin, and slightly messy, short cedar brown hair. He also had a pair of large and golden wings on his back. In contrast to other angels that have appeared thus far, Adam's halo was bright gold in appearance, and similar to the Exorcists, has two spikes pointing up and down from each other, though these spikes are located at the front of his halo. He wore a white and golden cloak that appears to have a large 'A' symbol emblazoned on the front, and had gold-tipped spikes on the back of his collar. His visible hands were black in appearance. He was the first human man created and the first human soul to enter Heaven. After becoming an angel, he became the commander of the angelic military force known as Exorcists, and served Heaven as forerunner of the Extermination movement. Adam appeared very egotistical and unsympathetic. As the leader of his Exorcist army, he took his stance as the Exorcists' head figure very seriously, sending antagonistic threats towards demons and anyone for standing in their way or whoever disobeyed his command, as he did so with Vaggi for refusing to kill a Sinner, cutting her wings, and leaving her in Hell. He also displayed traits of extreme narcissism and chauvinism, believing himself the perfect man due to being the first and claiming he had never made a mistake in his life, since he was the first man to be born on Earth, and he claimed that all the male bloodline came from him and brag about how big and great his dick is.
