In the Silver Millennium, Daricon tried to spark conflict between the Earth and the Moon by starting the Black Stars, an anti-moon terrorist organization. They destroyed whole sections of Crystal Tokyo with bombs and attacks. The Zodiac Senshi were dispatched to eliminate the Black Stars. Before Gemini committed suicide, they worked together to destroy Daricon�s body, and lock his soul away into a glass sphere, much like a crystal ball. They hurled the sphere into the sun, then set forth to destroy the high-ranking officials.
Somehow, he managed to survive. Ridding on a gust of solar wind that lashed very close to Earth, he dropped back to the planet hundreds of thousands of years later. Through his powers he discovered, to his rage, that the Zodiacs had been reincarnated. But reborn as well were his slaves, Andromeda and Orion, whom he once again found and persuaded into his circle.
Daricon's most useful power is that his is wonderfully persuasive. After being restored with his servants, he sought out the remaining Zodiac Senshi, who had been imprisoned in the ice of Pluto's moon Charon for centuries, revived them, and explained what had happened with their students. He managed to convince them that the Bright Zodiacs were 'traitors' and brought them to the side of the Black Stars.
Daricon's mission is to be reunited with his greatest power, the Black Nightmare, restore his body, and rule the universe. He imprisoned the Solar Senshi and wants to destroy the Sailor Zodiacs in revenge for destroying his body. The Black Nightmare is a part of Daricon himself, the remaining energy of his destroyed body, taking it�s own personality and life force. It partially-possess a specific human�s soul, and removing it would destroy its host. If Daricon manages to re-merge with the Black Nightmare, his body will be revived.
