Wicked Lady is originally Chibi Usa (Rini),
only turned to DarkMoon's side by the Dark
Crystals magic. And although Wicked Lady was
a creation of Wise Man, she haven't loose her
love and everythink...she has just forgotten it all.
And she actually turns to be the last villian in SMR,
besides Diamond and Wise Man, after Saphiru was killed.
Also Prince Diamond seems to fall in love with her,
after he didn't suceeded winning Bunnies (Usagi/Serena) love...
But Wicked Lady seems to feel lonely anyway
(it's like Wise Man controled her mind)
and thats why she atacks Sailor Scouts this hard and mercyless.
As far as I understand she uses the power of Dark Crystal to atack,
also she's using this real cool umbrella (I allways wanted to have such
one, but my mom told me that this way i'd look to girly *crying out loud*).
Luna Kitty Ball is also used as a weapon, well it's Rinis toy, so it
listens to her for allway^_^. So she travels with Prince Diamond back in time
and fights with Sailor Scouts, but than she's getting healed by Sailor Moons
magic and going back to the Sailor Worriors's side. Prince Diamond also realized
his mistake after that, but i'm not tolking about him at the moment.
