Jephthah Claudius is Dr. Rachel and Dr. Leah's father. He had red hair and a mustache with an unusual style. His wife is nowhere to be seen in the flashback where he appears, so it is possible that she was dead beforehand. After discovering Rachel's experiments on children at the Magnolia Compass orphanage and finding himself disgusted with her immoral behavior, he was soon killed by a God Arc Soldier Version Zero at the front of his mansion before he was able to expose Rachel's deadly intentions for her orphanage's children.
