Armx, once a RM-2020 espionage droid from MerenData that was altered, became a bounty hunter renowned for his poetry; he frequently composed epitaphs for those he captured. As an example, he penned an epitaph following the capture of his target, Gavron Noff.
Prior to its annihilation by the Rebel Alliance, Armx was initially stationed at an Imperial Naval installation located on Gestrex III.
