Great Mazinger:
A Mycenaean warrior dispatched to Earth to keep tabs on Dr. Hell and his Mazinger Z project, making sure everything aligned with the empire's broader agenda. He's willing to lend a hand to Dr. Hell when it suits him, but his real allegiance has always been to Mycenae.
Shin Mazinger:
The commanding officer of Mycenae's forces stationed on Earth. Physically, he's a hybrid creature—humanoid and green-skinned from the waist up, but a sabre-toothed tiger below. After his defeat at the hands of Zeus alongside the rest of Mycenae, he entombed himself in a statue hidden deep within Bardos Island, betting on a future resurrection so he could one day reclaim the island.
