Orion Fowl is Artemis's alter ego, created as a result of Artemis succumbing to Atlantis Complex. He makes his appearance in the 7th book, The Atlantis Complex, when Holly zapped Artemis with her Neutrino, and when shocked by Amorphrobots . Orion has a guilt-free, unrealistic, confident personality, with all of Artemis's memories and knowledge but none of his guilt. Orion is also free from the other symptoms of Atlantis Complex, including Artemis's irrational fear of four (which sounds like the Chinese word for 'death') and his belief of five as a lucky number.

Orion appears incapable to distinguish the difference of magical creatures of the real world and magical creatures in fantasy novels. Holly Short also stated that he had 'spent too much time in the back of Artemis's head'- he doesn't know how to interact with the real world. Orion has an obvious affection for Holly and expresses this in romantic lines and by calling her his "princess", much to her annoyance. He is extremely gullible to fantasy, as he suggests that Foaly and himself look for magic rocks and a secret birthmark to prove he is a prince. Orion speaks as though as he is a fantasy hero, calling Foaly a "noble steed".

However, Orion proved to be vital in the eventual success of Artemis's scheme, as when he was branded a rune and enthralled by Turnball Root, Artemis tried to get himself shocked to let Orion become the dominant personality. Orion had fighting skills he had learned from Butler which Artemis usually ignored, and defeated a similarly enslaved Holly and Turnball.

"How do I love thee? Let me see. I love thee passionately and eternally... obviously eternally - that goes without saying."

"Ladies don't look for birthmarks; that is work for jolly fellows, like the goodly beast and myself. Ladies, like Miss Short, do enough simply by existing. They exude beauty, and that is enough."

"I am not exuding anything." (Holly)

"You have displeased the princess!"

"But [Artemis's] sonnets are heartless, and that opera house he designed was totally self-indulgent."

"Very well. Then quiet it shall be. I would rather cut out my own tongue than utter one more word. I would sooner behead myself with a butter knife than speak a single -"

(At this point Holly jabs Orion in the solar plexus)
