We recently learned that Raidou, the original boss from Dead or Alive, would be appearing once again in Dead or Alive 5: Last Round and today Koei Tecmo officially revealed the character in his new cyborg form.
Accompanied by a gameplay video and a number of screenshots for the character, Koei Tecmo gave us an official description of how exactly Raidou survived.
Presumed dead after being defeated in the original DOA Tournament, Raidou was partially reconstructed with cybernetics and now returns as a half-mechanized killing machine. Having lost his memory as a side effect of his cybernetic upgrades, all that remains is his unquenchable thirst for power, and his willingness to use whatever brutal methods it takes to achieve glory.
Hailing from the same ninja clan as Kasumi and Hayate, Raidou was exiled from his own village when his brutal thirst for power went too far, only deepening his hatred of the clan. His fighting style is Mugen Tenshin Ninjutsu at its core, and he even possesses the ability to recognize and imitate the moves of opponents he has encountered, while keeping original techniques up his sleeve.
