The hero ninja Ryu Hayabusa stopped the evil Tengu, but not before Tengu triggered a massive worldwide collapse, draping the entire planet in a dense cloud of darkness and fear. DOATEC has lost its way, becoming a hunting ground for power-hungry scam artists. It's against this backdrop that DOATEC's development department — a fortress of cutting-edge military technology — sees the work of a genius bear fruit: following Project Alpha and Project Epsilon, the ever-ambitious Dr. Victor Donovan completes the Omega Project, producing a new superhuman, Genra. Once the leader of the Hajin Mon ninja of the Mugen Tenshin clan, Genra is no longer human but a force of singular, unprecedented power known as Omega. To test Omega's abilities, DOATEC announces the third Dead or Alive World Combat Championship.
