Adam was an Angel and the main antagonist of the first season of Hazbin Hotel. He made his official debut alongside his lieutenant, Lute, in "Overture".

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.

In "The Show Must Go On", he was defeated by Lucifer Morningstar and killed by Niffty.
