Dead or Alive World Combat Championship

The Dead or Alive World Combat Championship, also known as the Dead or Alive Tournament is a annual international fighting tournament, held by the Dead or Alive Tournament Executive Committee. The story of Dead or Alive revolves around the events of the tournament, and those who enter to fight.

History
The tournaments were created by Fame Douglas, the former head of DOATEC. The tournament was planned to be just that; a tournament held all over the world in different locations at a time, where fighters can compete for a vast amount of money. At the end, Kasumi made it to the final to face Raidou. Kasumi managed to damage Raidou; however, Raidou was too strong for her. Then, Ryu Hayabusa came to help Kasumi and damaged Raidou enough for Kasumi to defeat him. In the end, Kasumi won the tournament. However, she didn't accept the prize money, so Tina Armstrong got the money instead.

The following year, during the climax of the second tournament, it was revealed that a tengu had escaped from its own world, bent on the destruction of everything. Ryu eventually defeated it, winning the second tournament.

A third tournament was staged as a normal martial arts tournament, but it was really a testing ground for the genetically-engineered warrior Omega, created by DOATEC after experimenting on Genra. Fittingly, given that Omega was originally her adoptive father, Ayane was the fighter to defeat him.

During the fourth tournament, with all the antagonism aroused by DOATEC, the Mugen Tenshin Ninja Clan, led by Hayate seeked for revenge, after all the dirty work DOATEC has created. Hayate, Ayane, and Ryu went to stop DOATEC, with a reluctant Kasumi following them to try and stop them. The clan succeeds to destroy DOATEC and its headquarters tri-tower, but in the end it was Helena Douglas who self-destructs the building. With the end of DOATEC, it's unknown if the Dead or Alive Tournament will continue.
