D ' Marr D ' Marr was an alien trader , captain of his own starship . In 2151 , he discovered an apparently abandoned Kantare vessel on an alien planet . D ' Marr believed the ship was haunted . Later that year , D ' Marr dined aboard with Captain Jonathan Archer , Sub - Commander T ' Pol , and Commander Trip Tucker , during which time he learned Archer was interested in obtaining raw materials to fix " Enterprise " . D ' Marr was quite fond of coffee , and offered T ' Pol some Triaxian silk . In exchange for coffee , he gave the " Enterprise " crew the coordinates of the planet where he ' d found the seemingly deserted Kantare vessel . He told them that no one had salvaged the ship because it was haunted . ( ) Background information . D ' Marr was played by actor Tom Bergeron . The character ' s species and origin were not identified , the final draft script of " Oasis " describing him simply as " an exotic - looking alien trader " while the call sheet listed him simply as " Exotic Alien " . According to this call sheet , Bergeron filmed his scenes on Thursday on Paramount Stage 8 with a makeup call at 8 : 30 a . m . and a set call at 12 : 30 p . m . The prospect of Tom Bergeron , a Trekkie , appearing in came about while he was visiting Paramount Pictures ' studio lot and was being given , by " Enterprise " co - creator and Executive Producer Rick Berman , a personal tour of the show ' s sets with Whoopi Goldberg , a friend and colleague of Bergeron ' s who was meanwhile taking a break from filming Guinan scenes in . " " As we were walking through the various sound stages , I made a comment which showed my knowledge of the " Star Trek " universe . It was at that moment I was asked the question I ' ve always dreamed of : Rick asked me if I ' d ever considered doing a guest appearance on the show , and he was serious , " " Bergeron recalled . Berman then asked Goldberg if Bergeron could act . Despite never having seen him do so , Goldberg vouched for Bergeron as an amazing actor . He was invited to be a guest star a short while later . " " I made two requests : I wanted to have the full " Star Trek " experience and be transformed into an alien , plus I wanted to be killed at the end of the episode , " " Bergeron explained . ( ) The role of D ' Marr didn ' t disappoint Tom Bergeron . " " When I went into the costume fitting , " " he said , " " I learned that I had many lines and was featured in the entire opening scene of the ' Oasis ' episode . " " Bergeron ' s alien makeup took four hours , so he was given an 8 a . m . makeup call . Having watched many behind - the - scenes documentaries about " Star Trek " makeup , he knew what to expect . Following a dress rehearsal , Bergeron started filming the footage of D ' Marr that day , which went smoothly . " " In the afternoon , however , I started getting what I call ' lingo lock ' and began having trouble reciting all of the technical lingo that was required of my character , " " he admitted . " " I kept getting alien names and planet names mixed up , or I was mispronouncing them ! " " Bergeron ' s day as a guest star came to an end by 5 p . m . He was convinced he would always fondly remember the experience . However , the part he found most gratifying came at the end of that day . Despite being finished for the day , all the other actors had stayed behind to watch the close - ups of D ' Marr be filmed . " " When my shots were totally finished , the entire cast and crew give me a round of applause . I was on cloud nine after that , " " he reminisced . " " It was a magnanimous gesture for them to do that . " " ( ) In the course of the day , someone mentioned to Tom Bergeron that the name of his character was also the name of recurring character Damar , to which Bergeron clarified that the two names are spelt differently . He later joked that D ' Marr was the great - great - grandfather of Dammar . ( ) Since D ' Marr does not die in " Oasis " , Tom Bergeron hoped to reprise the part later in the series run of " Star Trek : Enterprise " . He even pitched , in person , a story idea to Rick Berman which would have facilitated this happening . " " Whether or not I get to do it again , I am very content to have had the experience [ of playing the character ] , " " he concluded . ( ) Ultimately , D ' Marr was not seen or mentioned again , though Bergeron did later appear in the episode as a Coridanite ambassador .
