'Baby Spark'

Baby Spark is Torch's niece. Torch kidnapped Baby Spark as an egg. When Torch was found by Baby Spark's father, Baby Spark freaked out, so her father sent her to live with Stone, who had been helping raise her. Baby Spark, now called Spark, lived with Stone until she was old enough to have everything explained to her. Then she went back to her father and lived there with him.
