Douglas Logan was the avatar taken up by Rygel in a Scarran-created simulation designed to break John Crichton's mind. Logan, an American, was the project administrator of the Farscape-1 mission and was unhappy that Crichton had crashed the module. He met with the astronaut to figure out a way to bounce back from their failure, but Crichton refused to take the meeting seriously, instead taunting the apparent Hynerian and flinging cards at his face. Given that much of Crichton's vision came from his own memories, it is not known whether there was a real Douglas Logan on Earth.
