Arnecio Ulvaw'op was a male Bothan who lived during the Galactic Civil War. He deserted the Galactic Empire sometime during the war and joined the Alliance to Restore the Republic's Crimson Phoenix Squadron as a pilot under major Eker on the planet Dathomir.
During his time at the Science Outpost on Dathomir, Ulvaw'op wore an orange colored Rebel Alliance shirt. The shirt was essentially a plain shirt, commonly worn by other beings, except that it was emblazoned with a red Alliance Starbird. He also wore black dress slacks and gray standard boots. Completing his uniform was a mercenary bandolier.
