Fisher ( Technician ) Fisher was a male Human Starfleet crew member in the 23rd century . He served in the sciences division aboard the in 2266 under the command of Captain James T . Kirk , while the starship was undertaking a historic five - year mission . He was a geological technician . Biographical record . In 2266 , Fisher participated in a specimen - gathering mission on the surface of planet Alfa 177 . During the mission , he fell off a rock bank , becoming covered in an exotic magnetic ore . This ore caused a transporter malfunction when Fisher was beamed back to the ship , which resulted in Captain Kirk being split into two distinctly different versions of him , one of whom was weak and indecisive whereas the other was possessed of all of Kirk ' s dark tendencies and animal instincts . Fisher later witnessed the psychologically bestial manifestation of Kirk trying to sexually assault Yeoman Janice Rand in her quarters , and was incapacitated by him while attempting to contact Lieutenant Commander Spock . Later , in sickbay , Fisher therefore confirmed Rand ' s assertion that she had been assaulted by Captain Kirk . ( ) Appendices . Background information . Identity . Fisher was played by Ed Madden , who previously played the geologist in two years prior . The character of Fisher was originally called Pollard . He was named that in two drafts of the story outline for " The Enemy Within " , the second of which additionally referred to him as a " crew technician " . The character was also called Pollard in the first draft and a revised draft of the episode ' s script ( the latter dated ) . He wasn ' t renamed Fisher until the final draft of the teleplay was issued ( on ) . Thereafter , in a set of research notes that Kellam de Forest wrote about the teleplay ( on 15 June 1966 ) , de Forest concluded there were " no conflicts " with the name Fisher . The novel " Present Tense " gives Fisher ' s first name as " Edward " . Depictions in story outlines . In the first draft story outline of " The Enemy Within " , Pollard was bludgeoned by the violent Kirk duplicate using the receiver of a wall phone aboard the " Enterprise " . Robert Justman proposed , in a memo of story notes from him to Gene Roddenberry ( on ) , that they omit the wall phone and that Pollard therefore be assaulted by either some other implement or the Kirk duplicate ' s bare hands . Justman also observed in that memo , " " The character of Pollard becomes confusing to me . The instability that he displays would certainly seem to me to disqualify him from service on board the USS " Enterprise . " In the revised story outline for " The Enemy Within " , it was an unnamed male " crew member " who was wounded while collecting some ore . The nature of his injury was also different , in that he was grazed by " a falling rock . " Pollard first appeared in the narrative while passing by Rand ' s quarters during her sexual assault . Stunned by the sight , Pollard rushed to the nearest " Transicator " ( an early name for the " Enterprise " s communication devices ) . He was shoved against a bulkhead by Kirk ' s double , though , and Pollard ' s face was then slammed against the door to an empty cabin , an act which knocked him unconsciousness . Moments later , he was found inside the cabin , his face described as " a mask of blood , " and , with a gasp before losing consciousness again , he identified the captain as his attacker . Pollard was then taken to the " Enterprise " s " hospital " , where he was referred to as being in serious condition . After regaining consciousness , the hospitalized Pollard , whose face was still bruise d and puffy , was personally visited by the real Kirk , who informed him the duplicate had been arrested . Despite the real Kirk apologizing for what had happened , Pollard eyed his visitor with distrust and , as Kirk left , nearly contempt . Robert Justman , in a memo of story notes to John D . F . Black on , suggested that , since the doors aboard the " Enterprise " weren ' t hinged , the writing staff would need to devise some other way of " disposing of Pollard . " He also critiqued , " " I think it ' s all right for Pollard to be distrustful of the real Captain Kirk , but I don ' t think Pollard should eye Kirk with contempt as Kirk exits . I think his expression should be more the expression of uncertainty , rather than downright dislike of his leader . " " In a memo of story comments Gene Roddenberry wrote Richard Matheson ( dated 26 April 1966 ) – in preparation for Matheson writing the first draft script of " The Enemy Within " – Roddenberry advised , " " We must clearly explain why the first man who was beamed up through the Transporter did not come out a double as happens to Kirk . " " In the same memo , Roddenberry relayed to Matheson that Pollard would have to be injured and knocked out some other way , as the " Enterprise " s doors weren ' t hinged . Scripted portrayals . In the first draft script of " The Enemy Within " , Pollard was whacked by the Kirk duplicate using a communicator . Robert Justman considered that implement too small and light - weight to be used as a weapon realistically . In a memo he wrote John D . F . Black ( on ) , Justman suggested Pollard ' s assault instead could be committed off - camera , Justman commenting , " " We need never see Pollard getting belted by Kirk ' s Double . We can hear it start to happen in the Bridge and then the audience will naturally assume that something terrible is happening to poor old Pollard . " " In a revised draft of the script of " The Enemy Within " ( issued shortly prior to ) , Pollard was discovered in a storage room with a brandy bottle after the Kirk double ' s attack on him , Pollard having been stowed there by the vicious duplicate ( the scene was referenced in a 3 June 1966 memo from John D . F . Black to Gene Roddenberry ) . By the time the final draft teleplay was submitted ( on 8 June 1966 ) , the character was no longer found to have been stowed in a storage room by the Kirk double . In the final draft script of " The Enemy Within " , the newly renamed Fisher , after having fallen off a rock bank in the episode ' s teaser , was advised by McCoy not to hurry back to work . Fisher agreed to comply with that instruction , despite admitting ( unknowingly to Kirk ' s violent double ) that his injured hand was " not too bad . " This was changed in the revised final draft of the teleplay , in which Fisher received and accepted McCoy ' s medical advice to return to duty but didn ' t admit that the hand was " much better . " In both the final draft and revised final draft of the script , Fisher was established as making his way from sickbay to his quarters when he witnessed the duplicate Kirk ' s attack on Rand . Also in both drafts , Fisher repeatedly made exclaimed requests to the bridge for help while being assaulted , himself , by the assailant . In the final edit of the installment , though , he is shown making only the first of those pleas , with the duplicate Kirk then shoving him to the ground . In the aftermath of the attack , Fisher was scripted ( again in both drafts ) to be found , by Spock , inside Rand ' s quarters , lying near where Rand herself was sitting . The script ' s stage directions described him as " " near unconscious , crumpled on the deck ; his face a mask of blood and bruises . " " In the final draft teleplay , Fisher then told Spock , when he asked who the attacker had been , that Kirk was the culprit . However , in the revised final draft , Fisher ' s reply was edited out , leaving only Spock ' s question , before cutting to the other " half " of Kirk in the next scene , asking incredulously , " Me ? " In the final edit of the outing , Fisher doesn ' t appear following the assault until he accuses that version of Kirk face - to - face , in sickbay , of the beating . Fisher didn ' t do that in the final draft , wherein he was being tended to by McCoy in sickbay but didn ' t say anything . However , he did have dialogue in the depiction of the scene from the revised final draft , acting exactly as he does in the final version of the scene ( although , in that revised draft but not on - screen , his presence elsewhere in sickbay was revealed by Rand before he appeared ) . During the sickbay scene , Fisher was characterized in the final draft as looking at Kirk " with cold suspicion , " whereas the revised final draft said he was " eyeing Kirk coldly . " Filming the character . For the filming of his scenes as Fisher in " The Enemy Within " , Ed Madden was assigned to work for seven days , starting on . On that first day of the episode ' s production , the immediate aftermath of Fisher ' s fall was shot , as was his subsequent arrival in the " Enterprise " s transporter room . Madden wore , for these initial scenes , some makeup on his hand , to make it seem bruised and at first slightly bleeding , as well as patches of yellow dust on his jumpsuit costume to resemble the ore . The scene in which Fisher ' s voice - over is heard on the ship ' s bridge while he is being attacked by the Kirk double was filmed on the third day of the shooting schedule , on 15 June 1966 . The next day ' s filming began with the scene wherein Fisher ' s injury is tended by McCoy prior to the Kirk duplicate interrupting . For that scene , Madden again wore bruised makeup on his hand , and now had very slight yellow detritus on his costume . Fisher accusing Kirk in sickbay was shot later that day , despite it taking place chronologically later than the attack itself , and involved Madden wearing bruise makeup on his face . The scene in which Fisher firstly witnesses a rape attempt on Janice Rand and is then actually assaulted himself wasn ' t filmed until the sixth day of shooting : 20 June 1966 . In both that scene and from then on , Fisher ' s hand was to be in a bandage . Though the scene to be filmed straight thereafter was planned to be the immediate aftermath of the attack – with Spock arriving at the scene of the incident – the episode ' s shooting schedule pondered if Fisher would be included in that ultimately discarded scene at all and , if so , whether his face would be " bloody & bruised . " The last scene described in the shooting schedule to include Fisher was the one in which he helps identify Kirk as the wrongdoer . As the scene was referred to in the shooting schedule , Fisher ' s face was , without question , to look " bruised - bloody . "
