The earliest known time that Orion was on Earth was in 79 A.D. There, he caused Mount Vesuvius to erupt, killing the population of Pompeii. He also appeared in Syria in 526 A.D. at the site of the Antioch Earthquake, and in 541 A.D. in Byzantium within weeks of the Justinian Plague.
Orion once battled the Headless Horseman at Valley Forge. He was defeated by Death and, upon defeat, Orion was trapped in Purgatory for two hundred years. When Moloch was killed by Jeremy with the Sword of Methuselah, he claims that Purgatory shook, allowing him to escape with several other minor demons.
Once escaping Purgatory, Orion ran into the Witnesses, Abbie and Ichabod, while battling demons. He then gave Abbie a symbol so that she could summoned him. As he attemped to kill death with his Halo Weapon, and steal his power with it, Katrina released the Horseman and Orion began his hunt. However, after Ichabod and Abbie discovered the angel's true purpose, the Witnesses set up to defeat Orion, and the angel's halo was destroyed by Ichabod using the Horseman's axe. Defeated, Orion then flew off, avoiding another defeat by Death.
