Adam

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 Vaggie 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. His narcissism was so great that, upon his defeat, he refused to admit how far he had fallen and expressed a god-like complex by proclaiming his enemies should be grateful for him having fathered the beginning of humanity while demanding they worship him for his deeds.

Adam did not appear to be aware that his egotistical and depraved behavior towards Lilith was the cause of her leaving him. When meeting Charlie Morningstar, he didn't hate her for being a child of the woman he was married to before she fell in love with Lucifer, and was relatively patient with her, although remained dismissive of her suggestions. Adam was also sexist, constantly addressing other women as "bitches" and enjoyed their sexual depravity, as he admitted to Vaggie that her forbidden love relationship with Charlie was "hot as fuck", albeit it is unclear whether this was about their genders or them being angel and demon. Despite this, he seemed to have a good relationship with Lute, whom he seemed to have in very high esteem, even though he was her superior.

Despite his obliviousness, Adam did show moments of common sense and self-awareness, such as when the death of an Exorcist was discovered, he knew that if they decided to kill the Sinners now after just one week after the most recent Extermination, then demons would catch on to how Exorcists can be killed. Adam also knew when to slow down on his egoism, after inadvertently exposing the purpose of the Extermination to all the courts of Heaven, including Sera, the highest seraphim authority in Heaven and the one who ordered that no one but the Exorcists can know.

Appearance: 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 colored 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.
