Sikozu Svala Shanti Sugaysi Shanu (called Sikozu), played by Raelee Hill, is a Kalish who grew up in Scarran-controlled space. She first appeared in "Crichton Kicks" and made her last appearance in "". She becomes an expert (albeit a book expert) on Leviathans, and eventually goes to work for a pirate group who harvest toubray (nerve) fibers from Leviathans. She meets up with Crichton while he is aboard the Leviathan Elack in the Leviathan's sacred burial space; she led the pirates there and they subsequently try to kill her to prevent her telling anyone where the burial area is. Crichton nicknames her "Sputnik" due to the shape of her hairstyle when they met. There is initial confusion at their meeting because she cannot tolerate translator microbes and so must learn all languages by hearing them. This may not be a species trait, given that she is later exposed as a Bioloid agent, and could be a consequence of that process instead. She is extremely intelligent and picks up information very quickly. She can "change her centre of gravity" so that she can walk on walls and ceilings, and she can easily reattach limbs that have been severed. She has to eat only a few times a cycle (year).
