Z0-0M, also referred to as Zeeyo Ohm, and formerly known as the Shroud, was a replicator droid of feminine programming that operated during the era of the Cold War.
This droid, designated Z0-0M, became active prior to the conclusion of the Galactic War fought between the Old Republic and the reconstituted Sith Empire. Irritated by her master's incompetence, she killed them and assumed the identity of the criminal spy "the Shroud," employing actors to impersonate her while she remained secure at her headquarters. Repeatedly thwarted by the Commander, she sought to eradicate their base located on Odessen. She orchestrated the capture of the droid HK-55 to duplicate his memories into a replica, intending to utilize this information to dispatch her current puppet to obliterate the Alliance base. In an attempt to erase HK-55's memory, she inadvertently wiped her own, transforming into a benevolent and naive droid devoid of any recollection of her past transgressions. Upon encountering HK, she assisted in his liberation and aided his escape, endeavoring to prevent the Shroud from destroying the Outlander.
Through a sequence of battles and encounters, she and HK eventually arrived at Odessen. There, they successfully apprehended the Shroud, who was revealed to be one of the numerous actors engaged by Z0-0M during her tenure as the true Shroud, before he could trigger the bombs strategically positioned around the Alliance Base. After HK neutralized the impostor, he engaged in a conversation with Z0-0M regarding her future, just moments before Lana Beniko, Theron Shan, and the Commander appeared, discovering two unfamiliar individuals alongside HK-55 in their War Room. He conveyed his weariness and pledged to elucidate the situation.
The character of Z0-0M was voiced by Cristina Valenzuela in Star Wars: The Old Republic: Knights of the Fallen Empire.
