Lt. Commander Sybill is the Chief Science Officer for the San Francisco Mothership.



A protege of Diana's, Sybill has developed her mentor's view of humans, that they are animals provided for the sustenance of the Visitors the survival of their home world. She is not above conducting unauthorised experiments beneath the notice of Catherine and is more than happy to kill one of her own to get what she wants. She is also the older sibling of Jade, whom she barely tolerates.
