In 2266 , Harrison served in the sciences division , and sat at a forward bridge station during a star mapping mission that led to a tense first contact with the First Federation starship " Fesarius " on stardate 1514 . 0 . Harrison was one of many bridge officer s who were violently ejected from their seat s when the " Enterprise " was forced to destroy a radiation - emitting space buoy operated by Balok . ( ) Harrison was working in a corridor while the " Enterprise " encountered Harry Mudd and his " cargo " : a trio of women . He took a good look at the women as they walked by . ( ) Harrison was working in the ship ' s biopsy lab in 2266 when " Enterprise " personnel were afflicted with an intoxication from Psi 2000 . Upon McCoy requesting a report from Harrison , a specific crewman began laughing hysterically over the speaker . Harrison was later at his post in sickbay ( wearing a sciences blue jumpsuit uniform ) , helping to restrain Hikaru Sulu , while McCoy tested antidote serums . ( ) Later that year , Harrison ( again wearing a sciences blue jumpsuit uniform ) was working in a corridor adjacent to Charles Evans ' quarters , at a panel labeled " atmospheric system " . Harrison carried out this work while Spock was standing beside him and was meanwhile aware that Spock intended to use a force field . After Spock stated he would activate the force field himself and that Harrison had permission to return to his duties , Harrison did so . ( ) In battle with a around stardate 1709 , Harrison took over for Lieutenant at the navigator ' s console on the bridge . ( ) Harrison was part of a security team that responded to a call of trouble at the ship ' s theater . Lenore Karidian stole Harrison ' s phaser to hold " Enterprise " crewpeople at bay . She accidentally discharged the weapon and killed her father , Kodos .

When sub - sonic vibrations were used to irritate Omicron spore - possessed crewmembers on that planet , Harrison was overcome by the effect and started fighting with Lieutenant Kelowitz and another crewmember . ( ) Appendices . Background information . Harrison was played by regular TOS extra Ron Veto . Harrison ' s name was mentioned in " Space Seed " , as the camera panned over Ron Veto . In this scene , the name Technician 1st Class Thule was mentioned as the camera panned over actor Eddie Paskey , who generally played Lt . Leslie , and he can be clearly seen wearing his lieutenant braids . Also , the camera has moved past actor Blaisdell Makee , who played Spinelli , by the time his name was mentioned . There is the possibility that Thule was the name intended for Ron Veto , who had no braids on his costume , since the name also refers to an Eskimo culture , indicating a possible Inuit background ( the actor was actually of Hawaiian descent ) . This would be consistent with other character names in the series that are used to describe place of international origin . The other use of his name , in " The Naked Time " , did not show Veto when the reference was made , and featured a communications response from Harrison that was dubbed over laughter voiced by John Bellah . Seeing as Veto was seen later in that episode , unaffected , its likely that the voice wasn ' t Harrison ' s at all , but rather Bellah ' s unnamed crewman character intercepting his call . Veto is one of only a few to wear the colors of all three divisions ( sciences blue , operations red and command gold ) , in his various appearances . Harrison was one candidate rumored to possibly be an antagonist in the film . Before the movie was released , a name for the villain was revealed to be " John Harrison " , though whether this was his actual name or merely an alias was undisclosed . , in the lead - up to the film ' s release , speculated a fifty percent probability that the character would turn out to be Lieutenant Harrison .
