Nightmare is an evil organization and villains in Yes! Pretty Cure 5. Their mission is to capture the Dream Collect for their leader, Desparaia so she could gain immortality and to bring despair to the world.
The base for the villains appears to be located in the middle of a city district. It is a huge skyscraper with many unseen offices, Bunbee's board room, Desperaia 's office on the top floor and a roof top. The whole layout is based on a Japanese corporation/evil corporation.
The subordinates that were sitting on the table wearing masks were the Palmier Citizens and were brainwashed after they got captured and brainwashed, and disguised themselves as humans. Soon in Ep.48, they've soon went back to normal selves and forms.
