In 3036 AD, Professor Gepetto Garibaldi began formulating ideas for the creation of a series of cybernetic soldiers. With the initial support of the Vatican Papal State, Garibaldi initiated the Homo Caedelius Series—cyborgs, also referred to as "Killing Dolls," that were fully mechanical with the exception of their organic brains and brain stems. The program was ultimately terminated in 3055 AD, however, when the Vatican government declared the HC Series to be inhumane.
