Series regular Hayate was originally introduced as Ein in Dead or Alive 2. Ein utilizes a similar karate style like Hitomi. Virtua Fighter character Jacky Bryant will be included in Ultimate so expect some familiar moves from his Virtua Fighter 5 Final Showdown moveset such as his lightning kicks appearing.
