KT-55

KT-55 was a feminine Assassin droid active during the Galactic War. Along with its twin PR-98, KT-55 was part of the Crimson Fang gang, which following the death of Empress Vaylin and formation of the Eternal Alliance in 3631 BBY took over Port Nowhere by force, planning to use the mobile space station as their base of operations. The Alliance send a strike team on a mission to liberate Port Nowhere, who systematically rid the station of Outer Rim's most notorious villains, eventually confronting KT-55 and PR-98 and destroying them.
