Metalia Endymion was 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. He was a Pretty Guardian Sailor Moon-only character.
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 Senshi. He also killed Mio Kuroki since Metalia had no more use for her.
- Metalia Endymion showed some similarity to Chaos Galaxia in the anime, in that they both sealed a powerful evil entity within their bodies and ended up being corrupted by it.
