~ Helena Douglas telling Kasumi about Alpha-152

Alpha-152 is the boss of the video games Dead or Alive 4 and Dead or Alive 5. She is a clone of the series' main protagonist Kasumi.



When the first Dead or Alive Tournament ended, Kasumi was captured by DOATEC. She was subjected to Project Alpha. The purpose was to create the ultimate fighter. During the first phase of Project Alpha, a clone was created and it was labeled as Kasumi A. In the second phase, the clone transformed into Alpha-152.


Victor Donovan secretly held Alpha-152 in a laboratory located on an oil rig. It awoke after Hayate was freed from Project Epsilon by Kasumi, Ayanne, and Ryu Hayabusa. They shinobi discovered Victor Donovan created additional Alpha clones.


Ryu is forced to fight the Alpha-152 and managed to defeat it. It rose and altered its appearance to resemble Ryu. Ayane and Hayate subdued Alpha-152 while Ryu used a ninpo spell to destroy the lab. While the lab crumbled, Alpha-152 decided to engage in a fight with Kasumi. After the fight, Alpha-152 incinerated with the burning lab.


Alpha-152 was created to hate the world and is focused to destroy everything in its path. It can be willing to fight anyone whether or not they attack it. Alpha-152 is completely inhuman compared to Kasumi A. Alpha-152 feels only hatred whereas Kasumi A has the ability to feel a minimum of human emotions. Alpha-152 hisses whenever it is positioned to fight. Occasionally, it will let yell in anger or frustration.


Alpha-152 is named after a letter in the Greek alphabet. Alpha is the first letter of the Greek alphabet. It is represented by Α (uppercase) and α (lowercase). In the system of Greek numerals, it has a value of 1. It was derived from the Phoenician letter Aleph which means Ox. Alpha - both as a symbol and term - refers or describes a variety of things. 152 refers to the clone's number. In Dead or Alive 5, there are other clones created by Donovan. Each one has it's own unique number.
