With the world's military weapon's seized by Dr. Hell and entire armies of Mechanical Beasts, the Photon Power Laboratory created mass-produced robots for Japan to have a chance to defend itself. With data from the Mazinger Z implemented into their design with specialization in attacks and abilities, multiple copies were create with the lead units piloted by exceptional pilots. Once in battle, the army managed to destroy legions of Mechanical Beasts but lost their commanders. While only a few robots of the Mazinger Army survived but were rendered unusable, the Mechanical Beasts and mobile fortresses were stopped. The other lead robot Venus A was destroyed but its pilot Sayaka Yumi survived.
- Venus A: The successor of Aphrodite A and piloted by Sayaka Yumi. The only model of its type in the battle compared to the others. Later used with Aphrodite's data to create Artemis A.
- Million α: Lead robot piloted by twin French pilots Lt. Lori & Loru and armed primarily with the Photon Power Electromagnetic Gun based on Koshiryoku Beam. 12 models were produced.
- Baion β: Lead robot piloted by Lt. Shun Azuma and armed primarily with a large compartment for the Rust Hurricane. 36 models were produced.
- Daion γ: Lead robot piloted by Major Masao Oide and armed primarily with large heat sinks for the Breast Fire. 108 models were produced.
