Renna

Renna was a Kaled mother-to-be who was selected by Davros to be part of his genetic experiments. Posing as her new doctor, he injected her unborn son with a new chemical which he claimed would make him healthier and stronger. He did not reveal that the child would be born a a mutant, a new species that would replace the Kaleds as the dominant life-form on Skaro. Renna died of shock during childbirth. (BFD: Corruption)
