Doctor Harley Sawyer, commonly referred to as "The Doctor", was the originator of the Bigger Bodies Initiative, and a former pupil of Elliot Ludwig. Ruthless, egotistical, and completely amoral, he orchestrated the systemic experimentation of hundreds to pave his elusive "golden path", only to be subjected to the same experimentation. His mind made into a prison of wires and terminals, his project stolen from him, he'd become just as much a prisoner as the experiments he created. In the years since the Hour of Joy, the Doctor has become a monster unburdened by any pretense of humanity, the final steps on his "golden path" seemingly within his reach.
