Doctor Terrence Thirteen was a genius inventor in 1880s Gotham City. A man of science and reason, he became an investigator and debunker of things others considered supernatural.
He later became a member of Stormwatch.
- Like his descendent's New Earth counterpart, Doctor Thirteen is disbelieving of all things supernatural. This goes as far as stating that he is not a ghost when he appears as one to the 21st Century Doctor Thirteen, noting he could easily be a hallucination.
