Jedite (Jadeite) - The first of Queen Beryl's Generals to steal energy for the Negaforce. Was originally one of Prince Darien's Generals, but Queen Beryl turned him and the other Generals evil. Attempts to steal energy were always consisted of stealing large groups of people's energy. Sentenced to frozen death by Queen Beryl when he failed to collect energy efficiently.
Neflite (Nephrite) - Second General to try stealing energy. Used the power of the stars to determine who his victims would be. He would accelerate the victim's maximum energy output and drain their energy when it reached it's peak. Fell in love with Serena's best friend Molly Baker, and saved her life when the DD girls came to kill him for not stealing enough energy. He died when one of their "vines" struck him through the chest, while he was protecting Molly.
Zoycite (Zoisite) - Third General, her/his mission was to collect the seven rainbow crystals (together they would create the Imperium Silver Crystal) and bring back the seven shadow warriors to Queen Beryl. Had a showdown with Tuxedo Mask for the three crystals he was able to take from her/him. Zoysite was sentenced to death because she/he disobeyed orders and tried to kill Tuxedo Mask. She/he was also in love with Malachite. The reason I am refering to Zoycite as she/he is because the original version Zoisite was a male. When it was later dubbed in English, Zoysite became female.
Malachite (Kunzite) - Last General, in love with Zoysite. Job was to get rid of the Sailor Scouts and capture the Imperium Silver Crystal. Failed and was killed by his own power when he fought Sailor Moon and she boomeranged it back at him using the Silver Crystal.
Tuxedo Mask/Prince Darien (Tuxedo Kamen/Prince Endymion) - After the battle with Zoysite, Darien was captured and brainwashed into becoming an agent of the Negaverse. Malachite and Darien fought about how they should capture the scouts and steal energy. When he fought Sailor Moon, she un-brainwashed him by reminding him of their love. He struck Beryl with a rose in the heart, and "died" after being struck by one of Beryl's ice crystals. Brought back to life after Sailor Moon's wish that everything would go back to normal.
Doom and Gloom Girls (DD Girls) - Five sisters that attacked and killed the Sailor Scouts on the way to Beryl's hideout. As each scout died, they killed of one of the DD Girls. Only the leader remained afterward because Beryl wanted Sailor Moon alive.
Queen Beryl (Queen Beryl) - Queen of the Negaverse, and followed the orders of the Negaforce (Queen Metalia). She tried to take over the Earth during the Silver Millennium, but she was defeated by Queen Serenity of the Moon Kingdom. During the present, Beryl has made her way back to Earth tried to take it over again. After being struck in the heart by Prince Darien's rose, she asked the Negaforce to give her the power to defeat Sailor Moon. The Negaforce gave Beryl it's power and she became "Super Beryl." She was defeated by Princess Serena of the Moon Kingdom and the Sailor Scouts.
Negaforce (Queen Metalia) - Evil force that directed Beryl to take over Earth. Gave Beryl her energy so that she could defeat the Sailor Moon.
