From a planet far in the future called Nemesis comes
a group of dark ememies of the future Sailor Moon
called the Black Moon Family. Amoung their ranks was
a warrior named Catsy. She had a hairstyle to match
her name which gave off the appearance of a set of catlike ears on her head. Catsy is one of four sisters
who along with their master Rubius were sent to Earth
in the past in order to find the daughter of Sailor Moon and capture the Imperium Silver Crystal of the
future. The Four Sisters fought the modern day
Sailor Scouts in numerous battles. Catsy herself could disguise herself and shoot out blasts of icefire. However, they she and her siblings soon discovered that Rubius was manipulating them the whole time. So they asked Sailor Moon to use the Crystal to change them to side of good. In doing so they lost all their super powers. Catsy then helped her sisters set up their own cosmetics service and stayed friends with the
Sailor Scouts from then on.
