Prince Endymion

Because Mamoru Chiba is his later self, the prince looks identical to him: a tall youth whose short hair catches a bluish sheen above a pair of blue eyes.

His battle dress starts with a long-sleeved bodysuit in dark blue, layered under a navy breastplate. Silver plating wraps his waist and lower back, reaching out to shield the hips, while armored boots in navy climb to the knee. A cape, black with red lining, fastens to silver shoulder guards, and a brown sash at his waist holds the scabbard for the sword he wields in combat.

Endymion is a devoted and honorable young ruler, quick to fall for Serenity and steadfast once he has. His loyalty extends to his people and to the Moon's queen, whom he pledges to help defend when war breaks out. A treasured music box that Serenity once gave him speaks to the tenderness of that bond, an heirloom that eventually finds its way to Usagi Tsukino in the present day.

The prince presides over a marvelous realm on Earth, and his path crosses Serenity's when she slips away from the Silver Millennium to see the planet for herself. Their romance deepens, and at some point she entrusts him with a music box that hums a gentle tune when it opens. That keepsake later belongs to Mamoru, then passes to Usagi after he loses it.

As conflict flares between the two kingdoms, he vows to stand with Queen Serenity against the assault of the enchanted Queen Beryl, who serves the cosmic evil Metalia. The war claims his life along with Serenity's. Drawing on the Silver Crystal's full might, Queen Serenity locks Metalia away and sends Endymion, Serenity, and the Guardians to be reborn on Earth for gentler lives.
