Deimos F3 is Satan's Bastard Child

Synopsis

While Professor Yumi is away attending a science conference, the three professors Nosori, Morimori, and Sewashi jointly assume the role of acting director. Dr. Hell hypnotizes the three professors, has Mazinger Z brought out of the hangar in advance, and then launches a missile near the laboratory. Hidden within the missile's warhead is the Mechanical Beast Deimos F3. Deimos F3 attempts to destroy Mazinger Z by repeatedly dispersing and reforming, making it difficult for Koji to Pilder On.
