A cam droid named 3DVO was the property of Lord Prepredenko from Jazbina. Unlike most droids, he possessed a unique sense of self and saw himself as a journalist. Remarkably, he was capable of deception, a trait uncommon in droids.
During Luke Skywalker's "rescue" of Princess Syayna, 3DVO was present. Floating on repulsorlifts, he recorded the entire event, unaware of secret modifications made to him. After Skywalker triumphed over his enemies, 3DVO unexpectedly fired a tranquilizer dart at him, and a beacon within him signaled Prepredenko's forces. It was revealed that the Jazbinans Skywalker had been fighting were actually Rebel supporters, working with the Princess against her father's wishes, leading to Skywalker's arrest.
Soon after, Darth Vader arrived on the planet, demanding Skywalker be handed over alive, no matter the cost. However, feeling used and betrayed by his transformation into a weapon without his consent, 3DVO informed Prepredenko that Vader intended to kill him. Princess Syayna then used a stun blast to fake Skywalker's death and offered to dispose of the body. Enraged, Vader ordered Prepredenko's capture and torture by his stormtroopers, ultimately leaving him mortally wounded in the dungeons.
Filled with remorse for his role in his master's downfall, 3DVO broadcast Prepredenko's final words from his cell, live on the public videonet, hoping to reach his daughter. Infuriated by this security breach and the message of defiance, Vader had 3DVO destroyed by a stormtrooper. Nevertheless, he passed away satisfied, knowing he had redeemed himself through this final act of journalism.
