Ruby Sato, middle name Angharad, is one of three children rescued as infants/fetuses from a Torchwood badfic. She and her siblings are written by Zingenmir.
Ruby was rescued as a baby from a Torchwood badfic in 2011, together with her younger sister Seren and her younger brother Owain. All three were adopted by one of the agents who rescued them. They call her 'Mama'.
While each child shares at least one biological parent with one of the others, none of them share both parents. Ruby is the biological daughter of Gwen Cooper and Jack Harkness.
In 2017, six-year-old Ruby was visited in the Nursery by Agent Jacques Bonnefoy, who serves as a sort of uncle figure to the three. She was very excited about her current art project.
In 2025, fourteen-year-old Ruby is mentioned to have a winning smile and the ability to pull off sounding both whiny and disgusted (though she won’t admit to it). As this is a Ten Years Hence story, it may or may not turn out to be canon.
The mission report detailing Ruby’s rescue has not yet been released.
