The male protagonist from the manga and anime Bishoujo Senshi Sailor Moon (aka. Pretty Soldier Sailor Moon) by Takeuchi Naoko. He is the major romantic interest of Tsukino Usagi, yet at the beginning of the series, both he and Usagi were on sour terms- and went out of their way to insult one another.
A car accident blocked his childhood and current memories, but opened up the memories of his previous life as Prince Endymion. This gave him visions of a girl (Princess Serenity) he was determined to find.
He is often portrayed as stoic, steady and introverted. And jumps at the opportunity to help others. Even as a civilian he has a variety of abilities and physical talents.
