Hirogen's Klingon simulation

A Hirogen Klingon simulation was created for a Hirogen hologram run aboard USS Voyager in 2374 that the Hirogens used to hunt the Voyager crew as prey. Not only were holograms used, but Kathryn Janeway was used as an interactive character, a Klingon warrior from the House of Mo'Kai. Captain Janeway, altered to look like a Klingon, battled several other Klingons and a Hirogen stabbed her. Neelix was also used in the simulation. The Klingons from this simulation were later convinced to fight against the Nazis in the Sainte Claire holoprogram, aiding the Voyager crew in their fight to take the ship back from the Hirogen.
