Servant of Death Phantom
Queen of Darkness
Black Lady is an evil grown-up version of Chibiusa Tsukino from when she was corrupted by Wiseman (Death Phantom) in the Black Moon Arc. This is the original depiction of the character created by Naoko Takeuchi.
Black Lady is an evil and corrupted version of Chibiusa. She came to be when Wiseman tricked Chibiusa into thinking that he was her ally.
Black Lady looked like a grown up version of Chibiusa. However, in this form, her hair's 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. 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 color 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.
Chibiusa goes to the Door of Space-Time after remembering how everyone in Crystal Tokyo teased her and how she met Sailor Pluto. But seeing Pluto so happy, she thinks that no one really needs her in Crystal Tokyo anymore. So, as she tries to get back to the 21st century, she, unnoticing this, then drops her key near the Door of Space-Time.
Since you can't get in any time period from the Door of Space-Time without the Space-Time Key, this shows you only a warp to be never seen or heard from again if you are warped in this hole. This is when Chibiusa realizes that she left her key behind. Wiseman then appears and pretends to be her ally, and comforts her by saying that he needs her. Wiseman then takes Chibiusa's hand, and a major space-time storm occurs after Chibiusa takes his hand. Pluto knows that this was caused by Chibiusa being in a major transformation.
Later in the next act or so, an adult-like woman who strongly resembles Chibiusa appears next to Wiseman as a shadow. She then introduces herself as Black Lady at the beginning of an act titled "Attack, Black Lady". She is often seen giggling evilly. She discards Luna-P, regarding it as a foolish toy. She attacks with black power and also hynotizes Tuxedo Mask to be on her side.
Sailor Pluto helps Sailor Moon stops Demande from touching the two Silver Crystals from past and future together, which would have destroyed everything, with Time Stop. Unfortunately in doing so cost Sailor Pluto her life. Black Lady mourns for her friend's death triggering her transformation into Sailor Chibi Moon.
Takeuchi struggled with a name for Black Lady, initially calling her "the Black Queen", and retaining her childlike appearance. Takeuchi 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 drawings of Black Lady.
