The Vori were a race found on a planet in the Delta Quadrant. They were engaged in a war with the Kradin. The war was reported to involve genocide and atrocities although there is no direct evidence of this.
The Vori utilized projectile based weaponry similar to 21st century Human weapons. They had a unique training method. They placed captured aliens (possibly also their own people) inside a training simulation that let the trainee witness Kradin atrocities and indoctrinate them to Vori military tactics and culture. The resulting soldier was fanatical in their desire to kill the Kradin "beasts". This method was used on Commander Chakotay of the USS Voyager when his shuttle crashed on the planet in 2374. (VOY: "Nemesis")
It is unclear what the Vori actually look like, because they only appeared inside the training program which used "a combination of mind control techniques, including photometric projections, heightened emotional stimuli and highly sophisticated psychotropic manipulation". When the program was used on Commander Chakotay, they appeared as Humans.
