Brianna Diggers is difficult to explain. In one of Gina and Britanny's earlier adventures, they were struck with a curse while exiting an ancient treasure vault in Iran. With Dr. Diggers and his magical abilities away from home, Gina attempted to "trick" the curse into leaving herself and Britanny by creating a soup of genetic material identical to their own. The curse, however, unexpectedly animated the biological material, creating a genetic cross between Gina and Britanny. Calling herself Grave Digger, the creature was now possessed by the curse and attempted to kill the sisters. As she was endowed with the abilities and memories of both girls, subduing Brianna proved very difficult, and was only accomplished when Dr. Diggers arrived home and 'removed' the curse. Today, Gina and Britanny think of Brianna as a sister. Her name was given to her as a combination of the names Gina and Britanny. Brianna has Gina and Brit's memories and experiences up to the moment she was born, but she is still immature. She has both Gina's love of technology and Brit's love of aggressive physical activity and recreation. The resulting fusion is the love of aggressive physical technology, like high-tech weapons and armor. Fortunately, she has a good friend in Genn to whom she can always turn to for help (and whom is often the focus of an out-of-control libido).
