The Uranus fighting tournament is a very popular martial arts tournament. One big difference between Uranus and other kinds of martial arts is that more than 2 participants fight in every round. People can participate in the tournament as a member of a group or alone. The place where the tournament happens is a labyrinth on a planet. During the tournament , a special fleet protects the planet where the tournament happens. At the beginning of the tournament, a group photo of every trainer and participant is shot and a special flame is lighted. The Klingon participants were always very good in the tournament.
