List of unnamed Vidiians.
Vidiian #1 was at the comm of a ship that came upon Voyager while it was in a state of flux due to a spatial anomaly, causing two Voyagers to appear. He informed his commander that the weapons systems and shields were down on Voyager, prompting the commander to order an attack. (VOY: "Deadlock")
The Vidiian #2 was part of a boarding party that attacked Voyager while it was caught in a spatial anomaly that caused a duplicate Voyager to appear. He shot and killed a duplicate Tuvok whose organs were then harvested. (VOY: "Deadlock")
In an alternate timeline this Vidiian captain was contacted by Kes after she had time traveled back to 2371 to seek revenge on the crew of Voyager, who she blamed for keeping her away from her people. The Vidiian captain was offered information necessary to capture Voyager by Kes in exchange for transport back to the Ocampan homeworld. (VOY: "Fury")
The Vidiian commander commanded a Vidiian ship that came upon Voyager and was puzzled by the sensor readings that suggested that Voyager was trapped in some sort of anomaly. When told that its shields and weapons systems were down, he decided to take advantage of the situation. He ordered his ship to fire on Voyager, and attached his vessel to the undamaged version of Voyager. He ordered a boarding party to harvest the crew's organs. (VOY: "Deadlock")
Vidiian guard 1Edit
This Vidiian guard was in charge of a work group that included Tom Paris and Pete Durst. They were being held in Vidiian mine that also served as a medical experimentation camp. Later, the guard told Durst that the prefect of the camp wanted to discuss Durst's request to contact his ship. Paris tried to intercede and go in his place, but the Vidiian guard took Durst. Durst was killed by Sulan, a Vidiian surgeon, who grafted Durst's face over his own.
When B'Elanna Torres tried to get access to the computer console in the sleeping place, the two guards surprised her and tried to bring her away but were knocked unconscious by Torres' Klingon half.
Vidiian guard 2Edit
This Vidiian guard came to take Pete Durst from his sleeping quarters on a Vidiian mine that also served as a medical experimentation camp. He and Tom Paris, along with B'Elanna Torres, had been captured by the Vidiians.
Later he and the other guard surprised Torres when she tried to get access to a computer console and tried to bring her away but were stopped by Torres' Klingon half.
The Vidiian surgeon was part of a boarding party that attacked Voyager. Due to a spatial anomaly a duplicate Voyager had appeared underneath the original Voyager. The surgeon harvested the organs of the crew on one of the Voyagers as soon as they were killed by the Vidiians. (VOY: "Deadlock")
