Female android assassins created by Kenzo Kabuto and serving Baron Ashura, the Gamia Q appear as identical young women with blonde pigtails and blue eyes. Their standard attire features purple sleeveless tops with yellow skirts, white belts, and boots; alternative portrayals show red sleeveless sweaters with white skirts and boots. For specific operations, they function without clothing, covered only by long black capes and shoes, revealing their mechanical joints.

Functionally designed for assassination, they possess high agility, strength, reflexes, and advanced martial arts proficiency. Their primary weapon is metallic hair, functioning as razor-sharp cutting implements capable of slicing through nearly any material, including Super Alloy Z suits, with only photonic energy barriers known to resist it. Typically executing commands with minimal autonomy, Gamia Q3 demonstrates instances of independent decision-making and tactical planning, such as using nudity to distract targets during combat. Communication is limited primarily to target identification, though Baron Ashura relays messages through implanted radios.

Their narrative history begins with Gamia Q1, Q2, and Q3 targeting Koji Kabuto at the Kurogane House under Ashura's orders. After attacking staff and engaging the Kurogane Five guards, Q1 and Q2 are destroyed, while Q3 is captured and taken to the Photon Power Laboratory. There, scientists identify Kenzo Kabuto as their creator. Later, aboard the flying fortress Saluud, the remaining Gamia units (Q4 and Q5) attempt to thwart Koji, Boss, and Sayaka Yumi's escape. Q4 is subdued by Boss and his allies, while Q5 is destroyed by Koji's Photon Blaster. Gamia Q3 remains the sole surviving unit after being repaired and retained operational.

In expanded media, the Gamia Q do not appear in the original Mazinger Z anime series but are referenced in the film *Mazinger Z: Infinity*. A parallel group of triplets in *UFO Robot Grendizer* (episode 50) fulfills an identical narrative role.
