EXD-9 was an Imperial Infiltrator Droid with masculine programming, who served the Galactic Empire as a recon droid. Disguised as an RQ protocol droid, EXD-9 was capable of morphing for combat and was armed with built-in blasters.[2] Around two years before the Battle of Yavin,[1] the droid was assigned to probe the planet Atollon—location of the Phoenix rebel cell's Chopper Base—for any rebel activity. Lasat rebel soldier Garazeb Orrelios and C1-series astromech droid Chopper found EXD-9 damaged by the krykna spiders in the Atollon wilderness and brought him to their base. Initially disremembering his mission, the recon droid eventually attacked them and RA-7 protocol droid AP-5. The rebels managed to deactivate the droid and sent him back to the Empire after reprogramming him to self-destruct.
