Aries, a pilot of an A-wing, flew with Riot Squadron, a squadron fighting for both the Rebel Alliance and later the New Republic. The pilot Aries met their death sometime while serving with Riot Squadron. Wyl Lark, another pilot in Riot Squadron, recalled Aries' name, among other fallen comrades, during the 204th Imperial Fighter Wing's attack on the Hellion's Dare frigate, which occurred a few weeks following the Battle of Endor in 4 ABY.
The 2019 novel Alphabet Squadron, penned by Alexander Freed, marked the initial mention of Aries.
