DOATEC was originally headed by Fame Douglas, the creator of the Dead or Alive Tournaments. The DOATEC had a huge empire in the weapons market, which made the Douglas family rich and famous, with homes around the world and a private army. After Fame's assassination, the company was inherited by his eldest daughter, Helena Douglas. However, the companies' majority leadership fell to Victor Donovan. After many occasions, the Mugen Tenshin Ninja Clan, who had frequently fallen prey to DOATEC's experiments, destroyed DOATEC's primary headquarters in revenge.
