 Quatermain, Nemo, Jekyll and Hyde, Dorian Gray, and Professor  Moriarty all "died" in their original novels or stories. In the  novel "The Invisible Man" Dr. Griffin went quite mad and was  eventually killed. Here, Skinner says he got the serum to turn  himself invisible from a mad doctor, a very clever way to get around  the rights issues. Both the original Invisible Man, Mr. Hyde, and  Nemo were far from heroes in their original incarnations. Nemo was a  rebel to the crown and Mr. Hyde and the Invisible Man were murderers  and rapists.
