Kazon

First encounted by the U.S.S. Voyager when it was sent to the Delta Quadrant. The Kazon were once under control of other aliens, until they took over the aliens' ships and divided into different sects.

Some sects are: Olga, Nistrim, and there are many more.

Their ships consist of huge battleships, bigger than the Dominion Battlecruiser and Romulan D'Deridex Warbird, to small shuttles.
