• History: After the first Dead or Alive Tournament ended, Kasumi was captured by DOATEC and was used as a subject for an experiment known as "Project Alpha" - a project that created the ultimate fighter using the DNA of the best martial artist in the world, who, at the time, was Kasumi; as she won the tournament and had killed Raidou, the then most powerful fighter of DOATEC.

With samples of her DNA, DOATEC started to make multiple clones of Kasumi, including Kasumi α, who later become an important part of Donovan's plan. Although Kasumi was saved by Ryu Hayabusa and DOATEC Germany, the company's science headquarters, was burned down, DOATEC continued the project by using Alpha as the main subject.

Using data collected from the third tournament and Project Omega, DOATEC experimented on Alpha's genetic make-up, resulting in the superhuman weapon known as Alpha-152.

During the Mugen Tenshin clan's attack on DOATEC, Helena Douglas tells Kasumi that Alpha-152 is entering the final start-up stage, ready to destroy everything in its path. After defeating Helena, Kasumi goes to engage in one-on-one combat with the clone. When Alpha-152 has a chance to leave the battle, it is fought by other fighters like Hayabusa, Ayane, Hayate, Zack, La Mariposa, Brad Wong, and Jann Lee. However, it ends up fighting back with Kasumi. It fights Kasumi throughout DOATEC's destruction and, in the end, the clone teleports away to escape.

Alpha-152 is still under the ownership of Donovan who has it hidden in the secret MIST laboratory located on the oil rig. It is found and defeated by another Alpha clone, who believes herself to be the real Kasumi. However, Alpha-152 presumably survives and reawakens when the true Kasumi, Ayane and Ryu infiltrate the lab to save Hayate from Project Epsilon. They discover that it is not the only Alpha clone, as Donovan has created other clones, each with their own number, and Phase 4 is about to begin. Although Ryu defeats it, it rises once again prompting Ayane and Hayate to defeat it. But then Alpha-152 shifts its form, from Kasumi's physical look to Ryu's, and launches a Gessen Goryu Ha Ninpo attack on Ayane and Hayate. But as they dodge the attack, the real Ryu counters with a ninpo attack of his own, resulting with the destruction of the lab. As the lab crumbles, Alpha-152 has one final battle with Kasumi and is defeated by her for good. After the fight, the clone is defeated, vanishing in a bright light, but yet is still not fully gone.

• Appearance: Alpha-152 is very different in appearance compared to the other clones in the past; while the rest of the clones are perfect copies of Kasumi, Alpha-152 only bears Kasumi's body shape. It is totally transparent, a green-blue color, and appears shiny and shimmery, like it is made from liquid or gel. Its eyes seem to glow white, with no pupils or irises. Alpha-152 appears to be completely nude. However, it lacks nipples, anus, and female genitals, with these areas being flat.
• Personality: This clone was created to hate the world and with a focus to destroy everything in its path. It has been shown to willingly fight anyone, whether they attack it or not. It's unknown if DOATEC has any control over its actions, or if it is allowed to run riot and could turn on the DOATEC at any moment.

Compared to Kasumi α, Alpha-152 seems to be inhuman. While Kasumi α seems to have the ability to feel at least a few emotions she always laughs as if amused, and is seen smiling smugly at the real Kasumi. Also, while Kasumi α stands normally and seems to be able to talk like Kasumi, Alpha-152 rarely ever talks, considered it to be 'pointless' and 'unnecessary' and instead makes animalistic noises, such as hisses, and stands ready for battle in a crouch, fingers curled, as if ready to pounce. It does however speak in an empty, monotonous tone that lacks any emotion.

Alpha-152 has developed and seems to be more vocal in its expressions. When attacking or taunting its opponent, it seems to murmur or hum. Occasionally, it will let out a yell of anger. She does not seem to handle losing well at all
