Alpha-152 (read as "Alpha One-Five-Two") is a recurring boss in the Dead or Alive series. It first appeared in Dead or Alive 2 as Kasumi α, and returned in Dead or Alive 4 and Dead or Alive 5 as the final boss. It was a clone of Kasumi and the penultimate product of Project Alpha. Based on the DNA of Kasumi, it was originally a normal clone dubbed Kasumi α that was created by Victor Donovan and the Dead or Alive Tournament Executive Committee. During the second phase of the project, Project Alpha-2, Alpha's genes were modified, resulting in it being transformed into a powerful inhuman creature. Alpha-152 was supposed to go on to be the ultimate fighter and to be a great weapon for DOATEC but the plan failed after the Mugen Tenshin clan invaded DOATEC's headquarters.
