An Alder-Espirion hybrid hailing from the planet Espirion held the position of captain aboard the starship Espirion Multi during the war that pitted the Galactic Empire against the Rebel Alliance. During the year 0 ABY, a fleet of Alderaanian ships came under attack by an Imperial-class Star Destroyer situated in orbit around the captain's homeworld. This Alder-Espirion hybrid, known as Beon Beonel, upon hearing a speech delivered by Princess Leia Organa of Alderaan from her shuttle Lord Junn, directed their captain to fly out and provide assistance to the fleet.
Before the Espirion Multi unleashed its firepower on the Star Destroyer and obliterated it, the captain cautioned the smaller Alderaanian ships to leave the battle to them. After the confrontation, they participated in a celebratory event honoring the victory alongside the Alderaanians. Their physical features included skin with red and black coloration, white hair, and green eyes. They were attired in gray and tan robes, a style consistent with the clothing worn by Beonel.
The character of the captain, although initially without a name, made their debut appearance in the comic book titled Princess Leia 5. This comic was penned by Mark Waid, features illustrations by Terry Dodson, and was released on July 1, 2015.
