During the Clone Wars, V2A DAZ functioned as a forensic science commander within the Coruscant Security Force. This droid created a report regarding the autopsy of Senator Onaconda Farr after his death. The report concluded that Farr had been murdered using a poison of Kaminoan origin, which was only effective on Rodian blood. This led Inspector Tan Divo to commence an investigation.
In the Star Wars: The Clone Wars season 2 episode called "Senate Murders," V2A DAZ was initially referenced through Aurebesh writing displayed on a datapad held by Divo.
