Metalia Endymion is a name given to the entity formed when Prince Endymion absorbed Queen Metalia's power within himself in an attempt to seal it away, but was instead corrupted by it. This character was only seen in Pretty Guardian Sailor Moon
Metalia Endymion spoke in the same deep metallic voice as Queen Metalia and only uttered the words "destroy" and "planet." He wielded a sword which he could use to absorb and throw back the attacks of the Sailor Guardians. He also killed Mio Kuroki since Metalia had no more use for her.
