Every year, a martial arts tournament, is held on the Earth. This is a huge event and draws the Earths top fighters from all across the globe. It also draws a huge audience. A sold out stadium, and millions watching athome on tele. Alot of press also show up. (Much like Wrestling ^_^).
Alot of fighters enter the tournament but only 16 can enter. (In the 25th they had a punching machine, the 15 strongest punches plus the World Champion qualified). When the 16 have been announced, the fighters must draw numbers, to see when they'll be fighting, and who against.
