A transformation caused by reaching the 7th Black Box, Majin Change. At this state, the pilot becomes attached to some of the wires and circuitry which enters their body, becoming a part of Mazinger. Through the use of the Metamorphosis black box, the blades on its body can be used for various close combat attacks. In this form, Mazinger gains a great increase in power, enough to destroy an entire planet. However, the pilot and robot enter a frenzied rage causing them to destroy anything in sight until nothing is left.
ZERO possesses a sentient artificial intelligence that merges with its pilot, allowing it to move without one and even have a personality. ZERO desires to be the only super robot in existence and the presence of another Mazinger is one of the things that can set it off, desiring the destruction of this obstacle above all else. Due to the link between the pilot and Z, if any of the pilots possess a state of madness ZERO will be activated.
After consuming multiple timelines, ZERO had managed to become its own independent entity no longer held back by a pilot or even a reality- Possessing enough power to influence other realities where it is the only Mazinger or super robot in all of existence. The only threat to ZERO however was its main pilot, Koji Kabuto who was influenced by the changing timelines and is able to indirectly control the Reality Manipulation Black Box.
