Dr. Regis Blackgaard is a primary villain in the radio drama series, Adventures in Odyssey.

He worked as an international terrorist, but often went under the disguise of a businessman, inventor, and entrepreneur. Blackgaard's terrorist activities include stealing computer programs and implanting viruses (both technological and biological). He stood against all ethics and morals, and was a ruthless and manipulative man. Blackgaard killed himself when he refused to escape a tunnel that was rigged with explosives he set up. He claimed that he was already dying of a virus he had used to murder others with, and would have died anyway.
