has first appeared in Dead or Alive 5 during the story mode's introduction cutscene, where she attacks and destroys Bayman's special forces team in a war zone. She has debuted as a playable character in the Arcade version of Dead or Alive 5 Ultimate, after which she was made available as downloadable content (DLC) in console version after with the new character Marie Rose. Unlike the other clones, Phase-4 wants to live as a human being. She has her own, very different fighting style, which mixes the moves of Kasumi and Ayane. According to Joystiq, Phase-4's various costumes "bear the trademark hypersexuality that Team Ninja infuses into all of its games" but "generally revolve around a hood, making her the most brooding, angsty version of Kasumi to date." She was not originally planned to return in Dead or Alive 6, however was eventually included as a bonus character in a pre-order DLC package, listed as Phase 4. In the sixth game's main storyline, the mass-produced Phase 4 clones are the enemy characters, while the previous black-hooded Phase 4 who attacked Bayman's army and ran away is presumably mentioned by Lisa.
