Karr as the Nazi Kommandant

Karr was an Alpha Hirogen who commanded a group of Hirogen hunters invading USS Voyager in 2374.

Karr's forces transformed much of Voyager into a holodeck, so that he could hunt the crew in holographic simulations of many historical eras and planets, including Earth's World War II and Klingon battles. Karr, in the Nazi simulation, wore the uniform of a German colonel. Some of the Hirogens under his command wanted to kill the crew and move on. He believed that the hunt had consumed the Hirogens and that their race was dying out because of the hunt. With a holodeck, they could keep the hunt tradition without having to spread all over the quadrant to do it and devote more time to maintaining their culture.

After Kathryn Janeway became aware of the situation, and the holodeck emitters started to fail causing the safety controls to go off line which resulted in bloody fighting on the ship, she and Karr agreed to a cease fire. She agreed to trade the holodeck technology in exchange for her ship and crew back. However, the Beta Hirogen, Turanj, refused to obey Karr's command and killed him. (VOY: "The Killing Game", "The Killing Game, Part II")

Background

Karr wears the uniform a full Colonel in the SS, which would have been known as Standartenführer. His medals appear to include the Iron Cross and among his ribbons can be seen the Sudentenland Medal, Eastern Front Medal, and a Waffen-SS service award.

Karr was played by Danny Goldring. Referred to as Kommandant Karr, it is not clear if this was his real name, or the character he represented in the holosimulation, as most Hirogen Alpha are referred to only by a title.
