When Dead or Alive 5 Ultimate debuts in Japanese arcades, players will be introduced to an additional character not seen in the game's newly-released console incarnation.

Who exactly this new fighter might be remains a mystery. The Dead or Alive 5 Ultimate roster includes almost every notable character found in earlier Dead or Alive entries, and with the addition of Rachel and Momiji from Tecmo Koei's Ninja Gaiden franchise, developer Team Ninja is running out of potential cameo characters. Neither Tecmo Koei nor Team Ninja have offered any hints on the fighter's identity.

It was revealed in July that Dead or Alive 5 Ultimate: Arcade will be distributed to Japanese arcades via Sega's "ALL.Net P-ras MULTI Ver. 2," a digital platform that delivers games to online-capable arcade cabinets located in Japanese amusement centers. To date there's been no mention of a Western release for Dead or Alive 5 Ultimate: Arcade, nor any word on when the game might debut in Japan.
