Black Lady

Black Lady is an evil adult version of Chibiusa Tsukino from when she was corrupted by Wiseman.

Appearance
Black Lady is drawn to look like a aged up version of Chibiusa, with longer hair and her eyes glassy as to distinguish her eyes from Chibiusa's. She is also a bit shorter than Sailor Moon. She wore 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.

Pretty Soldier Sailor Stellar
Black Lady first makes her debut in Act 10, where she is revealed to be Chibiusa Tsukino corrupted by darkness. She aides Wiseman in his plan to infect the Earth with the power of the Malefic Black Crystal. When the Sailor Senshi arrive and attempt to confront her, she attacks them, believing them to have been neglectful of her as a child.

Development
Originally, Naoko Takeuchi struggled with a name for Black Lady, initially calling her "the Black Queen", and retaining her childlike appearance. Naoko also noted that the leg-slit on Black Lady's dress was even more revealing in the anime than in the manga, something which shocked her, as she had wondered if the slit was going too far in her own drawings of the character.
