As Prince Endymion, Mamoru seems to possess no special abilities or magical powers of any kind; but carries a large sword as a weapon to brutally wound his enemies
Prince Endymion retains the same appearance as he did in the manga.
One thousand years ago, Endymion was the prince of a prosperous and mighty kingdom on planet Earth. He had met and fallen madly in love the tender-hearted Princess of the Moon, Serenity. But when the people of Earth were all brainwashed by the evil force of pure dark energy, Queen Metaria. Only strong-willed Endymion managed to maintain his sanity. He demanded his bewitched subjects to stop causing a meaningless war between the people of the Moon, but was stabbed to death by a trusted ally in a desperate attempt to protect his beloved sweetheart, Serenity.
One millennia later, Prince Endymion was reborn and reincarnated into modern-day Tokyo, Japan, as a young man named Chiba Mamoru.
