Stonroy Soma was a male Alderaanian who served as an aide to Senator Bail Antilles at the time of the Naboo Crisis, a duty he shared with Liana Merian and Agrippa Aldrete. A man with brown hair, light skin and rosy cheeks, Soma donned a draped overcloak of mauve fabric ornated with square motifs and golden lining, under which he wore an ankle-legth white tunic.
