Born in the midst of a violent storm, Sydney is Dwayne and Nicole's first and only child. She is naturally inquisitive, highly intelligent, and surprisingly mature for her age. She has a strong attraction and natural aptitude for technology and her vocabulary tends to far exceed that of her peers. She is obviously a "daddy's girl" and quite adept at manipulating her father.
In the alternate future explored during Surreptitious Machinations, Sydney became a freedom fighter in the resistance against Empress Trudy.
