Adonis was a character from Codename: Sailor V.
He is the reincarnation of the homonyme man who was in love with the goddess Venus. During the Silver Millennium, he was a soldier of the planet Venus who was sent to help Prince Endymion during the attack of the Dark Kingdom on the Moon Kingdom. During the battle, he came across Sailor Venus, with whom he instantly fell in love with. However, he wasn't able to talk to her because she apparently had feelings for Kunzite. He died during the battle and was reincarnated on Earth and became Danburite, the leader of the Dark Agency.
