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

He was the first human man created alongside the first human soul to enter Heaven. After becoming an angel, he was delegated to command over his personal private military force known as Exorcists and served Heaven as a forerunner of the Extermination movement.

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