Dr. Richard Dillon
Father of Travis Dillon and Bradley Dillon. In order to further his own career, he used his first-born son, Travis, as a sort of behavioral experiment, continually badgering the boy about everything. Richard disapproved of Dillon's career choice and felt that Dillon should have practiced psychology in Baltimore just as the first-born Dillon males had done for generations. The only time Richard really spoke during the cruise of the SS Pomposity was when he was complaining about Dillon. Ragoo stuffed Richard in a supply locker and took his shape in order to try and kill Dillon and Hawkins. All Ragoo succeeded in doing was angering Dillon to the point of striking him. This punch showed that "Richard" was Ragoo, allowing the Klingons to blast the Changeling into oblivion. The real Richard worried that Hawkins would screw up all of his hard work on Dillon.

After Richard's death, he informed Dillon of the truth through his will and told him to contact one of Richard's colleagues, Dr. Bunch, to continue the experiment. (The Star Traks Reunion Special [TRK])
