Sikozu Svala Shanti Sugaysi Shanu, or simply Sikozu was a Kalish bioloid, an operative of both a myterious organization which employed her to study Leviathans (of whom she became a book expert) and the Kalish resistance movement. When her former employers, the Grudeks decided she was no longer needed, she was forced to join John Crichton and later the crew of Moya in order to survive. An expert in several fields of science and an exceptionally intelligent person, she proved herself useful to the crew on numerous occasions. Eventually, she allied herself with Scorpius, seeing him as her best chance of survival and path to succes. Sikozu was planning, logical, calm and cunning, or as Crichton once put it, "too smart".
