Sikozu Svala Shanti Sugaysi Shanu (Raelee Hill) is a Kalish who grew up in Scarran-controlled space. She meets Crichton at the beginning of Season 4 and accompanies him as he reunites with his crewmates from Moya. She gradually allies herself with Scorpius, and they eventually become lovers, and she takes a place at his side when he is kicked off Moya.
During the Scarran-Peacekeeper war, it is revealed that she is a bioloid (a type of android) and a double-agent: she is working with the Kalish resistance to free the Kalish from Scarran servitude but she is really a Scarran spy – in exchange for a promise from them to free her people from servitude. Scorpius has long known this but does not act on it for some time. Finally, Scorpius assaults her after revealing his knowledge about her betrayal and leaves her for dead on the water-planet Qujaga, though it is left open that she might live.
Raelee Hill originally tested for the role of Grayza and although she didn’t get that role she was hired anyway; when they settled on the role of Sikozu for her.
Annie Single (season 4) and Angela Conte (The Peacekeeper Wars) were the hair and makeup supervisors for straight makeup: Dave Elsey was the creative supervisor for special effects makeup.
Raelee Hill ‘had to endure three weeks of twelve-hour days of test makeup sessions, before they settled on her final look.’ Despite this Sikozu’s appearance drifted a bit during the series: not just the obvious changes in hairstyle, but also both the detail and extent of her skin patterning.
Like some of the other characters, Sikozu’s appearance changed again in The Peacekeeper Wars – probably a result of time constraints and lower production values.
