Raidou no longer has his memory from previous Dead or Alive games in Dead or Alive 5: Last Round, Team Ninja have revealed. Here’s Raidou’s backstory and description for Dead or Alive 5: Last Round:
Presumed dead after being defeated in the original DOA Tournament, Raidou was partially reconstructed with cybernetic parts 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.
Dead or Alive 5: Last Round will be released in North America and Europe this February. The game is in development for Xbox 360, Xbox One, PlayStation 3 and PlayStation 4.
