The Queen of Darkness is the evil incarnation of grown-up Chibiusa Tsukino, who was corrupted by Wiseman. She has been reborn and is now the Queen of Nemesis. Devoted minion and Servant of Wiseman/Death Phantom.
A grown up version of Chibiusa. However, in this form, her hair is longer and her eyes are described by Naoko Takeuchi as "done like glass balls" so that they can distinguish her eyes from Chibiusa's. She is also a bit shorter than Sailor Moon. Wears a long black dress with a slit on each side. The sleeve and chest portions are organdy. The fabric of her skirt is also the same colour as the shawl that she is usually seen with. Also, the sleeve cuffs and collar have diamonds on them. Her footwear consists of satin high heels. She also wears black crystal earrings.
Distraught over the death of her closest and dearest friend, Sailor Pluto, Black Lady's crystal earrings shatter and she is transformed back into Chibiusa than for the first time, Sailor Chibi Moon.
