Doom & Gloom Girls

The Doom and Gloom Girls are a group of five Negamonsters who work for Queen Beryl and villains in the Sailor Moon series.

History
In Episode 40 "Day of Destiny", the Sailor Scouts were on their way to the Negaverse to fight Queen Beryl. When Queen Beryl asks her Youma subjects which of them would like to dispose of the Sailor Scouts and earn their place in Negaverse history, the Doom and Gloom Girls appear and volunteer for the job. They tried to trick Sailor Moon by disguising themselves as Tuxedo Mask, trapped, and nearly succeeded in trapping Sailor Moon, even though the others knew it was a trick. They then tricked Sailor Jupiter into thinking that they were Andrew, and then they trapped her with metal wires. They pulled her into a hole, presumably killing her, but not before she destroyed two of them (the red one and the blue one) with Jupiter Thunder Crush.

Their next target was Sailor Mercury. The three remaining Doom and Gloom Girls disguised themselves as Greg, but she was able to see through the illusion. But they managed to trap her anyway and presumably kill her, but not before Mercury destroyed the crystal on one of the girls that allowed her to create the illusions in the first place. Afterwards, they attempted to get Sailor Moon from under the ground, but she was pushed out of the way by Sailor Venus, who was trapped instead. She managed to kill the pink one with a Venus Crescent Beam Smash to the face, before apparently dying herself.

Afterwards, the two remaining girls captured Sailor Mars in a huge pile of rubble, where she destroyed them with Mars Fire Ignite, but was presumably also destroyed by them.

After the death of Queen Beryl and the Negaforce, the four Sailor Scouts reappeared, with their memories of being Sailor Scouts erased just like Serena. However, their memories would later return in Sailor Moon R when a new threat emerges.
