An artificial being created in a pocket universe, Supergirl came to our world and was raised by the Kents until setting out on her own. It was when she came upon the dying Linda Danvers that her life changed dramatically. Linda had been injured in a cult ritual, and having sworn an oath to Linda's parents that she would save their daughter, Supergirl sacrificed herself by merging her protoplasmic body with Linda's.
The blending created a new and unusual entity. However, for Linda Danvers, who had fallen far from grace, it was an entrance into a world seen through the eyes of a being who only looks for the best in others. For Supergirl, it was a connection to humanity and the granting of a human soul — albeit a dark and flawed spirit which she was able to redeem through great effort.
Together, they are a new and powerful incarnation that is, quite simply, an earth-born angel. An angel on earth with wings of flame, serving to protect the interests of both mankind and God.
