Ahri'ahn (more commonly referred to as Arion) is a fictional sword and sorcery superhero published by American company DC Comics. He debuted in Warlord (vol. 1) #55 (March 1982), and was created by Paul Kupperberg and Jan Duursema.

A powerful, immortal wizard from ancient Atlantis centuries before it sunk, the character originally starred in his own series taking place outside the main continuity of DC Comics. After the events of Crisis on Infinite Earths, the character's history was adopted into the Aquaman version of Atlantis, revised to be a demigod serving as a member of the fictional group of cosmic entities known as the Lords of Order. The character's magical and scientific exploits and heroism in the fictional mythology of Atlantis makes him both a reverred figure and the cultural progenitor of the homo magi race and their descendants, the atlanteans. Depending on continuities, he also serves as an ancestor to various characters in the DC Universe, including Zatanna, Aquaman, and Ocean Master.

While mentioned in other media, Arion would make his first animated appearances in the third season of the Young Justice animated series. While sharing similarities to his comic incarnation, he is instead cast with both a different parentage and is the biological progenitor of the homo magi and atlantean race.

Prior to the creation of the Arion character and his debut in his backup series, Kupperburg began coming up with new ideas that lead to his backup series when his then-editor, Laurie Sutton, mentioned that Dragonsword (the current backup of Warlord then) was eventually going to end. Sutton also mentioned the only requirement of the series was that it be set in the sword-and-sorcery genre. Kupperburg suggested a story of a young mage while Sutton requested it to take place in the fabled location of Atlantis. During the creation of the series, the name of the main character was noted to be a difficult process but eventually, "Arion" was settled with the names "Tynan", "Atlan", and "Orin" as contenders. Although the names weren't used for the main character, the names appeared in both Arion, Lord of Atlantis and later Aquaman titles.

Arion has not been a contender in any CBUB matches.
