Undeveloped Star Trek : The Original Series episodes Numerous undeveloped " Star Trek " episodes were written for . These stories were submitted or developed for production , but for various reasons never aired . " Star Trek is . . . " , the very first series outline , listed a number of short ideas for episodes , some of which were later worked out . David Gerrold presents his case of failed story , outline or script submittals during his early attempts to write for . These outlines were later presented in his book " " . " An Accident of Love " . " An Accident of Love " was a story assigned to writers Allan Balter and William Woodfield during the first season . However , the story assignment was cut off abruptly by the series production staff . ( " " , p . 361 ) " Aladdin ' s Asteroid " . Step outline by Robert Barry , dated . The story concerned a spaceship disguised as an asteroid . Although Barry ' s outline , according to the producers , was original and imaginative , it was deemed too expensive to produce . However , the concept was later reused in . ( " " , p . 461 ) " Alien Spirit " . Story outline by Norman Katkov , dated spring , . Inspired by the 1958 sci - fi film " It : The Terror from Beyond Space " , the " Enterprise " is invaded by an invisible , powerful alien being , capable of smashing rooms and tossing crewmembers through the air . Roddenberry and his staff disliked the concept , deeming it too violent and too expensive . ( " " , p . 356 ) " The Aurorals " . Story outlines by Frank Paris , dated and . This story dealt with an alien race kidnapping Kirk , Spock and McCoy in order to use their genes to create a gene bank , providing a way to survive for their infertile species . Meanwhile , they replace the trio with android duplicates on board the " Enterprise " . The crew soon begins to suspect their fellow officers to be imposters , as they behave oddly and unlike their real counterparts , and form a mutiny against them . ( " " , p . 519 ) The re - fertilizing concept is similar to , while the android replacement part bears a striking resemblance to . " Bandi " . " Bandi " was a story premise written by David Gerrold that he submitted in . Gerrold adapted his story for the third volume of " " . Though Gerrold later speculated that Kirk would instead temporarily take command of another starship to investigate reports of laxity , his outline primarily set it aboard the " Enterprise " . Kirk discovers there ' s a mascot smuggled aboard by a crewmember ; the creature , named Bandi , has an empathic ability to cause sympathy for it . Kirk wants it confined but Bandi always gets out by persuasive empathy to a crew member nearby . When a crewmember dies because of a distraction caused by Bandi , Kirk wants it off the ship ; Bandi turns the crew against Kirk , but once Spock kills Bandi , the crew snaps out of it . This behavior by the crew led Gerrold to speculate Kirk temporarily commanding another ship where the problem happens . Gerrold also said if the outline sold , he ' d come up with a better name than Bandi . Nevertheless , the name was later reused for , the pilot episode of . " The Beast " . Story outline by director Marc Daniels , dated . Daniels ' outline had Kirk and three crewmembers in a shuttlecraft visiting a planet rich of " summium " , a rare and precious mineral . However , the " summium " is guarded by " The Beast " , a caretaker , who captures Kirk while the three crewmembers escape . When the " Enterprise " arrives , Kirk is beamed up , however , he still remains in the clutches of " The Beast " . Finally , Anthropology Officer Janet Matthews , an Esper , is able to communicate with the creature , and convinces it to release the Captain . Producers Fred Freiberger and Robert Justman never took a liking to Daniels ' story , and it was soon scrapped . ( " " , pp . 518 - 519 ) " Bem " . Story outlines by David Gerrold , dated and . Additionally , in a period spanning from to , there was material correspondence between Gerrold and Gene Roddenberry about this proposed episode . The episode was intended to introduce the character of Bem . The reason why Gerrold named both that alien and this episode " Bem " , an oft - used acronym for " , " was simply because he thought it would be fun to have a true bug - eyed monster on " Star Trek " , even though the alien character was not intended to be one and ( at least in Gerrold ' s opinion ) there were never any bug - eyed monsters in the original " Star Trek " series . ( audio commentary ) The story ' s premise was related to prejudice , which was inspired by the push for civil rights that was occurring at the time , as many people were talking about the nature of prejudice . David Gerrold recalled , " " People were saying that ' Prejudice isn ' t logical , ' and I said , ' What would happen if you had a logical reason to be prejudiced ? " " Gerrold postulated the repercussions of having the very logical and emotionally - controlled Spock be the individual who became prejudiced . ( " Bem " audio commentary ) The question of what Spock might be prejudiced against , since there would have to be a logical reason for the reaction , then occurred to Gerrold . ( ; " Bem " audio commentary ) The writer reckoned that having the character become prejudiced against an alien would be interesting . Gerrold realized that the alien would have to be highly illogical and finally settled on the decision to make the alien a kind of practical joker . ( " Bem " audio commentary ; ) Gerrold concluded , " " That was where ' Bem ' started , with Spock having a logical reason to be prejudiced against Bem ' s bad behavior . " " Gene Roddenberry granted Gerrold a contract to write the episode . ( " The Trek 25th Anniversary Celebration " , p . 50 ) The first of the story outlines involved the " Enterprise " struggling to courier a small team of scientists from a dismantling planet in the Zeta Omicron system to a position where they could observe their sun go nova . As well as Bem himself , this episode also featured the once - only character of Dr . Isaacson – the leader of the scientists and an absent - minded , glasses - wearing professor type . The outline included a reference to Christopher Pike and culminated in Spock , having been specifically targeted for Bem ' s practical jokes on the ship ' s crew , being irradiated by the nova ( causing his skin to turn green with radiation burns ) but Bem using his limbs , which could operate while detached from the rest of his body , to rescue Spock . In a tag set in sickbay , it was revealed that the reasoning for all of Bem ' s joke - playing on the crew was that Bem , unaware of the discomfort it had been causing Spock , had been expecting a practical joke to be played back on him , as a sign of acceptance . Spock had obliged , having given Bem a hot - foot . ( " The Trek 25th Anniversary Celebration " , pp . 51 - 52 ) The book " The Trek 25th Anniversary Celebration " ( p . 51 ) , in which an essay examines the details of the two story outlines , comments that the character of Dr . Isaacson was " obviously based " on Isaac Asimov . David Gerrold admitted that this plot had problems , mainly centering around making Bem more responsible for the difficulties on the planet ( rather than naturally - occurring problems due to the planet ' s break - up , such as earthquakes and storms ) and writing Kirk as being more definite in the story ' s climax . Following the changeover of show - runner from Gene Roddenberry to Fred Freiberger , Gerrold was called in ( by Freiberger ) to rewrite " Bem " . Roddenberry spoke to Gerrold about the story , and the narrative ' s writer liked some of Roddenberry ' s ideas . Wanting to take advantage of the opportunity , Gerrold compromised and agreed to write a revised version of the plot , in hopes of it satisfying both of them . ( " The Trek 25th Anniversary Celebration " , p . 52 ) The second version had Bem sabotaging a mission to determine whether the ape - like creatures of Zeta Beta II were civilized . It involved Bem trapping Kirk and Spock on the planet and fooling the rest of the " Enterprise " crew that the two senior officers were actually dead ( as such , the outline included talk of the " Enterprise " returning to base , Kirk being buried on Earth and Spock on Vulcan ) . In this case , the episode ' s resolution involved Kirk and Spock ( the natives having come to regard Kirk , because he showed them how to make tools , as a god ) managing to capture Bem , a landing party from the " Enterprise " beaming to their location and Bem finally explaining that he was actually a psycho - sociologist who had been trying to conduct an experiment . In the outline ' s conclusion , Spock wondered – back aboard the " Enterprise " , as the ship departed the planet – whether the natives would use the concept of tools to construct tools or weapons and the creatures confirming , for the reader , that the former was true . ( " The Trek 25th Anniversary Celebration " , pp . 52 - 54 ) Fred Freiberger was still unhappy with the narrative . ( " The Trek 25th Anniversary Celebration " , p . 54 ) Even though David Gerrold had submitted ( together with the original outline ) some sketches for the design of Bem ' s species , Gerrold later remembered , " " We never got there because Gene left the show and Freddy Freiberger came in [ . . . ] I had the [ revised ] idea for ' Bem ' , but he said , ' I don ' t like that , either . " " Gerrold elaborated , " " There were more important stories to tell [ . . . ] Even though Gene was interested in it , for the third season of " Star Trek " , when he left and Fred Freiberger came in , there was a different storytelling agenda on the map . " " ( " Bem " audio commentary ) Dorothy Fontana said of the story , " " We thought it could not be done well in live action . " " ( ) She clarified , " " It was impossible to do , in terms of production , at that time . " " ( " " , p . 32 ) The story outlines ended up in David Gerrold ' s possession and , at one point , he was storing them in his garage . Although never developed for TOS , the episode ( along with , another story that David Gerrold unsuccessfully suggested for TOS ) was ultimately developed for ( for more information , see ) . " Beware of Gryptons Bearing Gifts " . Story outline by David P . Harmon , dated . This story featured the " Enterprise " being shrunk down to miniature size and placed on a tabletop ( similarly to ) by a strange alien race . The producers didn ' t see much point in the story , and also deemed the notion of crewmembers being chased by a giant cat to be a rip - off from , and shut it off in an early stage . ( " " ) " Chicago II " . " Chicago II " , also known as " The Syndicate " was a story outline by George Clayton Johnson , based on Gene Roddenberry ' s idea " President Capone " in his original series proposal , " Star Trek is . . . " , dealing with a parallel development planet where the gangster mobs took over and rule society . Johnson ' s story didn ' t quite work out , and Roddenberry assigned him to work on instead . Later , in the second season , Gene Coon and David P . Harmon resurrected the story idea and turned it into a comedy , titled " Mission Into Chaos " and later , . ( " " , p . 356 ) " Dead Man ' s Shoes " . " Dead Man ' s Shoes " would have been about a planet of assassins . ( ) " The Deadliest Game " . " The Deadliest Game " was once described by Robert Justman as " playing aboard the on a quest for , which is a fountain of youth located on a hell planet ! " ( ) " Deep Mudd " . Following and , a third TOS episode featuring the character of Harry Mudd was originally planned . Titled " Deep Mudd " , the story was written by regular Mudd writer Stephen Kandel . ( " Starlog Issue # 117 " , p . 44 ; " The Star Trek Interview Book " , pp . 133 & 134 ) The plot was conceived as a direct sequel to " I , Mudd " , following Harry Mudd ' s entrapment on Planet Mudd , amid the androids there . " " Deep Mudd ' involves Mudd ' s escape from that world , after he tricked these particular robots into revealing to him the location of a cache of scientific equipment and weaponry left by their makers , " " explained Kandel . " " Suddenly Mudd found himself with very , very advanced armament , which he used to bribe a group of pirates into helping him escape . The problem was , of course , that he could control neither the weapons nor the real heavies he was supposed to be in control of , the pirates . They tangled with the " Enterprise " , on a planet with a surface of molten , viscous mud . And it went on from there . That was basically it : bailing Harry Mudd out of his own problems , getting control of this weaponry they couldn ' t destroy , and sending it into a sun . " " ( " The Star Trek Interview Book " , pp . 133 - 134 ) The episode could not go ahead because Mudd actor Roger C . Carmel was unavailable at the time , busily involved with a film . ( " Starlog " Issue # 117 , p . 44 ) The story ended up in Kandel ' s possession who , in a interview , remarked , " " I still have the story somewhere . " " ( " The Star Trek Interview Book " , p . 133 ) " Destination : Infinity " . Story outline by Robert Barry , dated . " Dreadnaught " . Story pitch by Alf Harris during the first season . ( " " , p . 361 ) " The Forbidden " . Undated story outline by science fiction writer Hank Stine . " The Forces " . Undated story outline by Charles Parker . " The Foreseeable Future " . Story outlines by Jean Lisette Aroeste , dated and . The story revolved around a race of telepaths with precognition abilities , who were able to see their own near future . One of the telepaths , a young woman , had a vision concerning Captain Kirk , telling him he ' s going to die if he leaves the planet . The main theme of the story was accepting our fate as inevitable and letting it happen , or trying to change the outcome instead . The producers were not impressed with Aroeste ' s outlines , leading her to abandon this idea and come up with another story instead , titled " A Handful of Dust " ( filmed as ) . ( " , " p . 519 ) " From the First Day to the Last " . Shelved envelope for " The Menagerie " by John D . F . Black , delivered 8 / 12 / 1966 " The Fuzzies " . " The Fuzzies " , later titled " A Fuzzy Thing Happened to Me . . . " , was written by David Gerrold and submitted in . This episode later evolved into . " The Godhead " . " The Godhead " was written by John Meredyth Lucas , with outlines dated , , and . The story was about an alien race who created a way to accumulate their vast knowledge , placing it in the mind of one selected individual . However , this person ( the titular " Godhead " ) became too powerful and delusional by all this , and decided to take over the " Enterprise " with the intent on conquering the galaxy . The story was developed further and selected by Fred Freiberger to be filmed as the 26th episode of the third season . However , NBC canceled the series without ordering the last two episodes , resulting in " The Godhead " never being produced . ( " " ) " Happy Birthday to You " . " Happy Birthday to You " was an abandoned " Star Trek " episode . ( ) " He Walked Among Us " . " He Walked Among Us " was a script written by Gene L . Coon and Norman Spinrad for TOS Season 2 . Story outlines were dated , , and . The first draft was dated , and a later draft dated . The producers approached Spinrad with the task to write an episode to be a vehicle for Milton Berle , who expressed interest in appearing on " Star Trek " . Also , since a tribal village set was available , they told him to write a story in which it could be used . The original story by Spinrad was about a primitive race called the Jugali , inexplicably employing technology well beyond their capacities , as a result of interference by Byrne , a Federation sociologist , who only wanted to do good , but it eventually resulted in terrible consequences . However , Producer Gene L . Coon rewrote the episode to become a comedy . The rewritten story involved a Federation health food nut taking over a planet , so flagrantly breaking the Prime Directive that Kirk can ' t ignore him . He has set himself up as a god , refuses to depart from the planet when asked to and has so tightly woven himself into the planet ' s society that Kirk is unable to force him to leave without completely disrupting the society himself . Unhappy with the result , Spinrad asked Gene Roddenberry to discard it , and " don ' t embarrass his show by shooting this piece of - - - - . " He told Roddenberry to " read it and weep . " Roddenberry agreed , and the episode was not produced . ( ) The script was resurrected once more , for the third season , by Fred Freiberger . However , it was scrapped again . ( " " , pp . 514 - 515 ) " Hitler ' s Father " . This story outline , dated , sees a temporal experiment result in a 19th century man known as Alois Schicklgruber accidentally beamed aboard the " Enterprise " , with the crew entertaining and befriending him as they work on a way to return him to his own time . Soon , however , the crew realises that in later life , he will change his life to " Alois Hitler " and have a son known as Adolf Hitler . This results in a dispute among the crew , with a Jewish geneticist advocating that the crew forcibly sterilize Schicklgruber so as to prevent the birth of his infamous son , but the " Enterprise " historian arguing that he cannot be blamed for the crimes of his son , especially seeing how he died when Adolf was only 13 years old . No writer is credited on the outline , though given that it appears as part of Gene Roddenberry ' s archive , he may have been the author . The story does not appear to have progressed beyond its initial outline . " Image of the Beast " . Story outline by science fiction writer Philip José Farmer , dated . In this story , the " Enterprise " discovers the wreck of an immense alien space ship crash - landed on a desert planet . The crew search the ghost vessel , and begin to experience memory losses and strange hallucinations . We learn that during a blackout , they had devices implanted into their skulls , allowing the telepathic aliens to communicate with them . The story was deemed both too expensive to produce and too cerebral for NBC by the production staff . ( " " , p . 362 ) Farmer subsequently published the dark erotic science fiction / horror novel also entitled " Image of the Beast " , which had nothing to do with his " Star Trek " proposal except for the title . " Japan Triumphs " . " Japan Triumphs " was a story outline assigned to Gene Coon by Gene Roddenberry in to be developed for the third season . Supposedly , it revolved around Japan winning World War II , thus creating an alternate timeline . However , it was abandoned by new producer Fred Freiberger , as Coon was too busy producing " It Takes a Thief " . ( " " , p . 516 ) " Joanna " . " Joanna " was written by Dorothy Fontana as the first episode to feature Joanna McCoy , the daughter of Leonard McCoy . The outline was submitted and was later heavily rewritten to become . The original story featured Joanna coming aboard the " Enterprise " and having a romantic fling with Kirk , causing major conflict between Dr . McCoy and Kirk , and Dr . McCoy and his daughter . " Journey To Reolite " . Story outline by Alfred Brenner , dated . The " Enterprise " is transporting the leader of the planet Acrid for peace talks to their neighboring world Reolite . The Acrids are harsh and militaristic , while the Reolites are peace - loving democratic humanist . The Acrid leader and his mistress , Galatea carry a rare " life - giving drug " as a gift to the Reolites , which also works as an aphrodisiac . Although it went unproduced , this outline served as a basis for the third season episode . ( " " , p . 356 ) " The Joy Machine " . Story outlines by Theodore Sturgeon , dated and . First draft teleplay by Meyer Dolinsky dated . This script was later novelized under the same title , " The Joy Machine " , by James Gunn in . Sturgeon ' s story ( first titled " The Root of Evil " ) , originally submitted for the second season , dealt with the population of a Federation colony getting addicted to a sophisticated machine stimulating the brain ' s pleasure center , which rewarded the workers with " hours of joy " in exchange for the work hours . Sturgeon ' s story was highly cerebral , and lacked any action - adventure , yet Robert Justman pushed for developing it further . In the next rewrite , now adding more jeopardy , Spock becomes addicted to the machine too . Fred Freiberger resurrected the concept for the third season , and assigned Meyer Dolinsky to develop it into a workable screenplay . Dolinsky reworked the story , which now took place on a planet inhabited by mentally ill people , and featured a love story for Scotty . The machine now threatened the entire crew of the " Enterprise " , and made both McCoy and Scotty its slaves . " The Joy Machine " was set to be produced as the 25th episode of the season , and the directorial debut of William Shatner . However , NBC cancelled the series after only 24 episodes of the third season , thus making the last episode produced . ( " " ) " The Land of Counter - Pain " . " The Land of Counter - Pain " was an abandoned " Star Trek " episode . ( ) " The Lost Star " . " The Lost Star " was written by John Meredyth Lucas . It was outlined on and . This was Lucas ' second writing assignment on the series after . The story revolved around a solar system located inside a powerful force field , hiding it from visitors . While penetrating the force field , the " Enterprise " gets severly damaged . Kirk leads a landing party to the nearby planet to find the materials needed to repair the ship , and discovers a race of primitive Humans , allegedly kept as slaves by a race called the " Old Ones " , living in a modern city . Eventually , through Spock ' s mind meld with Kollos , a female in training to become one of the leaders , it is revealed that the " Old Ones " have perished centuries before by a genocidal war they brought on themselves , and the force field was created to camouflage their solar system in order to prevent the surviving natives from harmful outside intervention . Only a few selected leaders are aware of the technological advancements left behind by their ancestors . Through the mind link , Spock convinces Kollos that the " Enterprise " crew and the Federation does not represent harm , and eventually – after repairs are completed – the ship is set free by Kollos creating a " tunnel in space " through the force field . The crew ( and the viewers ) are left to wonder if Kollos will incite changes on her world or be killed by those who fear it . Stan Robertson rejected the outlines , saying that though they ' re " well written " , they ' re " lacking excitement , color and emotional involvement " . Lucas went on to write instead . ( " " , pp . 466 - 467 ) " Machines Are Better " . Story outline by veteran science fiction writer A . E . van Vogt , dated . It was a revised version of van Vogt ' s previously rejected outline , " The Machine That Went Too Far " . In this story , the " Enterprise " discovers a desolated planet with only two survivors : a pair of android s named Number One and Number Two , with an apparent feud against each other . Beamed aboard the ship , the two androids continue their competing , and eventually Number One – who moves faster than light – takes over control of the " Enterprise " . Although more developed than van Vogt ' s previous submission , this story was still mostly unsuitable for television , and resembled another story involving androids , . It was eventually turned down by Stan Robertson , who favored " I , Mudd " over it , and the story was scrapped . ( " " , pp . 458 - 460 ) " The Machine That Went too Far " . " The Machine That Went too Far " was an abandoned " Star Trek " episode . ( ) The story outline by A . E . van Vogt and Jack Williamson was delivered on , and a revised version was delivered by the same writers on . Story cut - off was exercised on . The story dealt with an android taking over the " Enterprise " , and resembled in some ways to the later episode . ( " " , p . 355 ) " The Magicks of Megas - Tu " . According to Larry Brody ' s book " Turning Points in Television " ( p . 129 ) , one particular story was written by him in for the third season of TOS – as he had been disappointed with previous installments of that season – and was sent to NBC by Brody ' s agent at the time , Sylvia Hirsch . In the book , Brody cryptically refers to third season producer Fred Freiberger as " Howie Horowitz " ( perhaps confusing him with Howie Horwitz , producer of the 1960s " Batman " and " 77 Sunset Strip " as well as the Gene Roddenberry pilot " The Questor Tapes " ) and relates about the plot idea , " " The subject matter was as true to me as the egotism of thinking I could show Howie H . how the show should be [ . . . ] Howie Horowitz passed on buying the script , and on meeting with me . " " Three years later in , Brody successfully pitched the same story , which involved the " Enterprise " encountering God in space , to Gene Roddenberry for the ( for more information , see ) . " Mere Shadows " . Story outline by Philip Jose Farmer , dated . The " Enterprise " rescues a woman from a wrecked ship , who falls in love with Kirk . Lovesick over his refusal of her , she arms herself with a phaser and takes over engineering , setting the ship hurling through space at never before seen speeds . This causes the " Enterprise " to break through into a space void and get trapped inside . The story was deemed too expensive to produce , however , elements from it apparently ( coincidentally or not ) resurfaced in . ( " " , pp . 361 - 362 ) A woman believing herself to be in a relationship with the captain , then taking over engineering and sending the ship hurtling out of control , is also central to the plot of Farmer ' s novella " The Shadow of Space " ( " Worlds of If " , November 1967 ) ; see entry under that title below . " The Microbe " . Story pitch by John Kneubuhl , which never made it further , due to the problems with Kneubuhl during development of his previous story , . ( " " , p . 466 ) " Miss Gulliver " . " Miss Gulliver " by A . E . van Vogt was to have been about a woman who grew to gigantic proportions due to an accident related to an unsuccessful experiment in regrowing limbs . At the episode ' s conclusion , her lover also underwent the experiment , so that he too could undergo massive growth , and the couple were left to found a planet of giants . ( ) Robert Justman commented that it " " bears a striking resemblance to – namely that someone grows larger and larger and larger . After that , it bears no resemblance to anything whatsoever that we would be able to depict on film . . . " " ( " " , p . 459 ) " Mission Into Chaos " . " Mission Into Chaos " was written by David P . Harmon and Gene L . Coon , with the first draft dated . This episode was heavily rewritten to become . " More Tribbles , More Troubles " . Meant as a sequel to , " More Tribbles , More Troubles " began development as an episode for the third season of TOS , intended to be the first aired installment of that season . ( " The Trek 25th Anniversary Celebration " , p . 50 ; ) After Fred Freiberger ( the producer of TOS Season 3 ) watched " The Trouble with Tribbles " on the morning before he first met David Gerrold and decided that he hated the episode ' s comedic tone , Gerrold consequently realized that Freiberger – who had essentially replaced Gene Roddenberry as showrunner – would not want a tribble - related sequel . ( " " , p . 97 ; episode audio commentary ) Gerrold recalled , " " I knew right then that – even though Gene had promised we were gonna do another tribble episode , in " Star Trek " s third season – I knew that it was dead . " " ( episode audio commentary ) Additionally , Gerrold remembered , " " I said , ' Well , Gene said he wanted a sequel , ' and [ Freddy Freiberger ] said that he had no interest . " " ( " Captains ' Logs Supplemental - The Unauthorized Guide to the New Trek Voyages " , p . 97 ) Gerrold concluded , " " He killed the second tribble episode for the third season . " " Together with David Gerrold ' s , this tribble - centric installment was one of two episode ideas that , despite never undergoing development for TOS , were successfully resurrected for ( for more information , see ) . Following the first broadcast of the episode ' s animated form , an adolescent , male " Star Trek " fan accused Gerrold of having plagiarized his idea for a tribbles - related sequel but Gene Roddenberry – in the knowledge that Gerrold had pitched the episode idea for the third season of TOS – simply asked Gerrold to " please handle " it . A reply letter that the writer sent to his accuser included the fact that he had planned the original tribble sequel for TOS ' third season . ( " More Tribbles , More Troubles " audio commentary ) " Mother Tiger " . Undated draft by Jerome Bixby . The script of " Mother Tiger " was written by Bixby in about four days . He later remembered the plot ; " " It was [ . . . ] about an alien in space in suspended animation . Her race had long since perished , but they had sent her forth as a racial mother , hoping she would be resuscitated on some planet , and restore her race . The " Enterprise " picks her up , and ends up leaving her on a planet after she creates all kinds of mischief aboard ship ; she ' s very powerful and intelligent . " " The reason " Mother Tiger " wasn ' t produced was that doing so was considered too expensive . Nonetheless , the script had several aftereffects and was very well received by the TOS creative staff . Recalled Jerome Bixby , " " They flipped over it , but said , ' We don ' t usually put $ 7 million into a " Star Trek " episode ' [ . . . ] While they couldn ' t use it , they said I had an uncunny feel for the show and made me one of their regulars [ . . . ] Several later episodes seemed to reflect elements of [ ' Mother Tiger ' ] , namely ' , with a racial mother , the rock creature . " " ( " " , issue # 164 , p . 48 ) " One Million B . C . " . " One Million B . C . " was a story outline assigned to Gene Coon by Gene Roddenberry in to be developed for the third season . However , it was abandoned by new producer Fred Freiberger , as Coon was too busy producing " It Takes a Thief " . ( " " , p . 516 ) " The Orchid People " . Story outline by Catherine Turney and John Collier , dated . In this story , the " Enterprise " receives a distress call from an unexplored planet . Despite objections by Spock , Kirk decides to investigate the matter , and finds two exceptionally beautiful men and an exceptionally beautiful woman on the planet surface . Beamed aboard the " Enterprise " , the three aliens turn out to be irresistable to anyone they turn their charms towards . The two males try to seduce the female crewmembers , while the female tries to lure Kirk . It turns out the aliens feed on the " life energy " of those they seduce , and that ' s how their race died out , by the stronger one nourishing the energy of the weaker . The three survivors made a pact never to use their fatal powers against each other , as they now have plenty of " food supply " among the " Enterprise " crew . Despite the story being deemed similar to , the production staff liked the concept , and hence they bought the story rights . However , as Turney and Collier relocated to Europe , logistics and time conflicts prevented it to be developed further . ( " " , pp . 457 - 458 ) " Pandora ' s Box " . Story outlines by Daniel Louis Aubry , dated and . This story dealt with the " Enterprise " discovering sentient rock creatures living on an asteroid intended to be used as a Federation outpost . The creatures feed on plutonium , and kill a couple of " Enterprise " crewmembers while attempting to eat from the portable nuclear generators brought to the asteroid . Kirk devises a plan to destroy the creatures , however , Spock discovers that when gorged , they emit an energy which can be harnessed to great use , and convinces the Captain to try communicating with them . Apart from being an apparent rip - off from , these outlines had many flaws , and the production staff quickly and unanimously decided to scrap the story . ( " " , pp . 469 - 470 ) " The Pastel Terror " . " The Pastel Terror " was written by Larry Niven . This story was never submitted but was published in the fanzine " Apa - L " in 1971 and in the fanzine " T - Negative " # 17 in 1972 . " Perchance to Dream " . " Perchance to Dream " was written by J . M . Winston , outlined . " Portrait in Black and White " . " Portrait in Black and White " was written by Barry Trivers , outlined and . Based on Gene Roddenberry ' s story concept " Kongo " in his series proposal " Star Trek is . . . " , this story dealt with a parallel development planet , where the " Ole Plantation Days " were occuring , with reversed roles of blacks and whites , with the white savages being shipped off and sold on slave markets operated by black traders . Stephen Kandel described the story as " " a show with a very militaristic planet being discovered , and the inhabitants were black . The only one they would talk to was Uhura , and they regarded the others as nothing . " " ( " Starlog " Issue # 117 , p . 44 ) In " The World of Star Trek " , David Gerrold revealed that DeForest Kelley had always wanted to see this story , featuring himself and Nichelle Nichols , described as " " something where the two of us were thrown onto a planet where there was a great racial problem , only reversed . The fact that I am a Southerner and she is black , and that we ' re trapped on this planet together . " " Despite Robert Justman ' s heavy objections about the story being too violent , and several aspects ( such as a " breeding farm " of white slaves ) being unacceptable to television censors , Roddenberry was very fond of this story , seeing it as a perfect example of the " " Gulliver ' s Travels " " concept he originally envisioned " Star Trek " to be , and pushed for it being developed further . The story was submitted to NBC . However , program manager Stan Robertson rejected it in a short and stiff letter , saying , " " We believe that this story does not fit into the " Star Trek " concept . " " Despite the rejection , Roddenberry still pushed for the story to be developed , ready to fight the network if necessary , and it went through re - writes by Gene Coon , Steven W . Carabatsos and D . C . Fontana . However , due to the lack of network support and the writers never being able to develop it into a workable form , the story was never produced . ( " " , pp . 358 - 360 ) According to Gerrold , " " A script version had even been written . And rewritten . And rewritten . ( . . . ) But either the premise was too touchy for television or nobody could quite make it work . The script never reached a form where Roddenberry or Coon wanted to put it into production . " " Stephen Kandel referred to the fact that the story was not given the go - ahead as " unfortunate " and went on to say , " " I would love to have done it . " " ( " Starlog " Issue # 117 , p . 44 ) Although the reference book " " ( pp . 197 & 399 ) attests that this story developed into , documentation from the series ' production disproves this and confirms that " Portrait in Black and White " was ultimately never developed . ( Gene Roddenberry Collection , UCLA ) " The Protracted Man " . " The Protracted Man " was written by David Gerrold and submitted . Although warp drive allows speedy travel , it still involves travel over immense distances ; Starfleet is participating in a test of a space warp corridor that will take seconds to cross several light years . The " Enterprise " will wait at the exit point to recover the shuttlecraft being piloted through . However , something goes wrong , the shuttle can ' t exit , and the pilot is beamed out from within the warp corridor . The pilot , however , is protracted : three visual representations – each of a different color ( e . g . blue , red , yellow ) – move a fraction of a second apart when the man is moving ; his voice is similarly garbled by a separation in time ; the pilot is drawing energy from the " Enterprise " to maintain himself . The protraction keeps increasing , particularly when the ship tries to move at warp speed to get to a point in space where all power can be shut down briefly to try to restore the pilot to normal . The transporter is used to reintegrate the man by dematerializing the multiple images then overlaying them . Gerrold was inspired by a " protraction " - type sequence in the film " West Side Story " ( which was directed by Robert Wise ) , wondering what the effect would suggest , then writing the script outline . In the movie , the teens go to a dance , with the teens appearing in a similar way , though the walls of buildings stay solid and grim - looking , by combining the film colors out of synchronization . A similar story appeared in and the " Farscape " episode " Through the Looking Glass " . " The Rebels Unthawed " . " The Rebels Unthawed " was a story outline written by Philip José Farmer . The " Enterprise " and its crew encounter a derelict space ship , abandoned and floating in space . Inside the craft , they find twelve passengers who are frozen in suspended animation . Once they are revived , it is revealed they were abducted from Earth by alien s , during the American Civil War . Adjusting to the future time period in which they have been awoken turns out to be considerably difficult for the newcomers . The outline was rejected because it resembled too much to , another story already in development . Farmer later wrote the " Star Trek " story treatment into a short story . ( " " , p . 362 ) This story also bears a resemblance to . " Return to Eden " . Story outlines by Alvin Boretz , dated and . The " Enterprise " comes across a planet with automated people , where everything is " perfected " : no crime , no hunger , no illness , no choice . But the society is completely sterile and the people are automated zombies of a computerized society . Robert Justman thought the story was awful . ( " " , p . 357 ) This story also highly resembles Roddenberry ' s , which was probably another reason why it was not purchased . " Rites of Fertility " . Story outline by Robert Sheckley , dated . An " Enterprise " crewman becomes infected with a strange " disease " . His skin hardens , his nails grow into leaves and he transforms into a living , thinking vegetable . The transformation soon affects the entire crew , except for Spock , who has an immunity . In search of a cure , Spock beams down to a nearby planet inhabited by a primitive Indian - like race , who worships trees and longs to one day become one with their gods . They are reluctant to share the cure until Spock explains to them that Earth people do not consider turning into a plant an acceptable form of immortality . The potential costs of Sheckley ' s outline were deemed to be far beyond the budget of a weekly television series , hence it went unproduced . ( " " , p . 357 ) " Rock - A - Bye Baby , Or Die ! " . Story outline by George Clayton Johnson , dated , concerning a newborn interstellar entity coming to life , aging , and dying within the " Enterprise " ' s computer and circuitry . The outline is collected in a hardcover omnibus of Johnson ' s writings , " All of Us Are Dying and Other Stories " , published by Subterranean Press in . A similar premise was the basis for . " The Search For Eternity " . Story outline by A . E . van Vogt , dated . In the story , the " Enterprise " crew awakens to find themselves unable to remember the past few hours . It turns out that during this time , Kirk apparently ordered the destruction of a populated planet , whose inhabitants now blame him with genocide . Recordings of the destruction and a missing photon torpedo appear to justify the claim . A Federation Admiral then arrives on his own starship , and orders Kirk to be executed by firing squad . It turns out all is , in reality , a ploy devised by a reptilian - looking species who have faked the attack and can pose as Starfleet members ( including the Admiral ) , in order to gain control of the " Enterprise " and wage war on the Federation . The story bears a resemblance to and . " The Shadow of Space " . " The Shadow of Space " was written by Philip José Farmer in . The " Enterprise " travels outside the universe . Farmer published a prose adaptation of the idea , under the same title , but with names changed from the " Star Trek " for copyright reasons . The story first appeared in the science fiction magazine " Worlds of If " and subsequently in a collection of Farmer ' s short fiction . " Shol " . Story outlines by Darlene Hartman , dated , , and . First draft teleplay dated . Hartman ' s story dealt with the " Enterprise " finding a primitive civilization living in a Garden of Eden environment under the control of a giant computer named Shol , which the natives consider to be a god . When Shol begins to " absorb " the " Enterprise " crewmembers into itself , Kirk and Spock are forced to destroy it . The natives are now left without their " god " and have to accept their loneliness from then on . This story went through several revisions , mostly because Gene Coon saw a potential talent in Hartman , and because both Coon and Gene Roddenberry thought it had a strong poetic quality . However , when Max Ehrlich ' s similar story , went into production , " Shol " was shelved . Coon still wanted to develop the story further , eventually assigning Hartman to write a teleplay , but after Coon ' s departure from the series the new producer John Meredyth Lucas ultimately scrapped it . ( " " ) The character of Dr . M ' Benga , however , who was introduced in this story , remained with the series and appeared in other episodes . Robert Justman tried to resurrect the story for the third season , but it never came to fruition . ( " " , p . 512 ) " Shore Leave II " . Story outline by Theodore Sturgeon , dated . The sequel to was assigned by Roddenberry to Sturgeon in . However , as Sturgeon already proved ( with " Shore Leave " , , and the unproduced " The Joy Machine " ) to write his scripts very slowly and having no real knowledge of writing television drama , and Roddenberry had enough of " baby - sitting writers " at that point , the assignment was eventually cut off at outline stage . ( " " , p . 516 ) A sequel to " Shore Leave " was eventually produced as , an episode of " " . " Sister In Space " . Story outline by Robert Sheckley , dated . Sheckley ' s second attempt after the failed " Rites of Fertility " outline had the " Enterprise " discover a long - lost Starfleet vessel , the USS " Yorktown " dead in space . Kirk , Scotty , Sulu , Rand and a few " redshirts " beam aboard and discover that an unknown and lethal alien creature killed the " Yorktown " crew . The creature attacks one of the " redshirts " , and rips him limb from limb . Aside its enormous strength , the alien monster is also a chameleon capable of blending into the background . The outline , which almost gave Robert Justman a heart attack , was deemed much too expensive to be produced within " Star Trek " s budget , so Sheckley was turned down once again . ( " " , pp . 357 - 358 ) The story seems broadly similar to the later and film franchises . " Skal " . Undated outline by Jerome Bixby . " Sketches Among The Ruins of My Mind " . " Sketches Among The Ruins of My Mind " was written by Philip José Farmer in . As with his previous " The Shadow of Space " , Farmer later used the idea as the basis of a published novella , though in this case he removed all vestiges of its " Star Trek " origin . According to Farmer , Roddenberry found the idea too sophisticated for a general audience . In the novella , an alien satellite enters Earth orbit and wipes ( or records ) everyone ' s most recent 4 days ' worth of memories once each 24 - hour day ; a person would lose the last 28 days ' memories by the end of the first week , etc . " Sleeping Beauty " . Undated outline by Robert Bloch . Bloch ' s second story after dealt with a 21st century gangster who puts himself into suspended animation to avoid being prosecuted for his crimes , found by the " Enterprise " centuries later . Gene Coon immediately nixed the idea , as it resembled too much to , a story already in development . ( " " , p . 362 ) Spock ' s leg story . At one point , Gene Roddenberry planned to do an episode set before the original " Star Trek " pilot , , in which Spock would have injured one of his legs . As a way to set the story up , Roddenberry asked Leonard Nimoy to limp during " The Cage " , an instruction with which Nimoy complied . " " But we never did an episode on Spock ' s leg ! " " Nimoy stated at Slanted Fedora convention in Las Vegas , where Nimoy also revealed the origins of Spock ' s limp in " The Cage " . " The Squaw " . Step outline by Shimon Wincelberg , dated , revised outline dated . " The Squaw " was written by Wincelberg as a " compensation " by Roddenberry for rewriting his script for . ( He also got to work on for the same reason . ) The story featured a lost colony of Humans who have based their society on the tropes contained in a third - rate pulp Western novel left behind by their ancestors . The planet is also inhabited by lost Vulcan s , who live in a primitive tribal state and aggress against the Humans . The Vulcans , it turns out , were peaceful , until the Humans arrived and began to harass and hunt them , like the Old West characters did with the Indians in the book . ( " " , p . 361 ) A number of the script ' s elements would resurface in later " Star Trek " productions . A book mistakenly serving as the basis for a civilization appeared in , in another way , . A very similar story premise was produced almost forty years later , as . " The Surrender of Planet X " . Undated outline by Don Masselink . " The Takeover " . " The Takeover " was an abandoned " Star Trek " episode . ( ) " Tomorrow the Universe " . " Tomorrow the Universe " was written by Paul Schneider . The first draft was dated and was intended for TOS Season 2 . The story dealt with a planet adopting Nazism – complete with swastikas and uniforms – after being culturally contaminated by a Federation visitor . Schneider ' s story bore a striking resemblance to John Meredyth Lucas ' . Despite being submitted much later , Lucas ' script was deemed to be much better and more developed , so Schneider ' s version was abandoned in favor of it . ( " " ) Schneider eventually filed a complaint to the Writers Guild of America . ( " " , p . 512 ) " Tomorrow Was Yesterday " . " Tomorrow Was Yesterday " was a sixty page outline written by David Gerrold in , intended to be a two - part episode . Gerrold stated that he wrote the story as a two - parter for two reasons : a ) " for more money " for him , and b ) " it would have meant a greater spread of money in the budget for sets , costumes and actors . " According to Gene Coon , " " Mr . Gerrold ' s outline was by no means inadequate . It is , as a matter of fact , very adequate . " " He further stated despite this , " " to film the two - part story outlined here would probably cost $ 6 - 700 , 000 " " and that it was " " too elaborate for television . What he has written is a good motion picture treatment for ideally a $ 2 - 3 , 000 , 000 picture . " " Gerrold attempted to turn the outline in to a novel during the late 1960s , but he took the story into a different direction , retitling the manuscript as " Yesterday ' s Children " , which was later published by Dell Books in July 1972 , and later renamed " Starhunt " . In he revisited his original story in the novel " The Galactic Whirlpool " . This story was completely unrelated to . The " Enterprise " comes upon a relic , a generation ship launched from Earth and long forgotten ; the people on the ship have forgotten why they are aboard or that there is anything outside the ship ' s walls . There are two factions aboard fighting each other . " The Uncoiler " . Story outlines by Philip Jose Farmer , dated and . This was Farmer ' s third attempt to pitch a " Star Trek " story . The crew responds to a distress call from an uninhabited planet , finding a ragged old man with long beard living inside a jungle . They also find the ruins of an ancient city , complete with a statue of a god probably worshiped by a long - dead alien species . Returning to the " Enterprise " , the crew begins to experience memory lapses and behave strangely . Kirk and Spock finally develop " on - again - off - again " amnesia . It turns out that the Zaltons , the extinct alien race preserved their minds in the statue , and are now trying to take over the bodies of the " Enterprise " crew , who they lured to their planet . Finally Kirk and Spock ( writing notes to each other whenever they get an idea , before they forget it ) find a way to exorcise the aliens from the crew . Both Gene Roddenberry and John D . F . Black deemed the outlines not interesting enough . ( " " , p . 362 ) The story is similar to , , and in certain aspects . Untitled Klingon two - parter . In a serialized essay across five volumes of trade paperback reprints of Alan Dean Foster ' s " Star Trek Logs " , adaptations of , the author explains that the original chapters he added to the adaptation of ( " Star Trek Log 7 " ) , at the request of publisher Judy - Lynn del Rey , were first proposed as a two - part episode for the third live - action season , and held over for a potential fourth season . This tale features a Klingon commander named Kumara , whom Kirk first met during a Starfleet Academy exchange program . " Van Vogt ' s Robots " . " Van Vogt ' s Robots " was a story assigned by Gene Roddenberry to D . C . Fontana on , based on A . E . van Vogt ' s two previously rejected story outlines , " The Machine That Went Too Far " and " Machines Are Better " . However , it was never developed beyond the pitch , as Fontana left the series before she could work on this premise . ( " " , p . 515 ) " The V . I . P . s " . Undated story outline by Gene Lasser and Malachi Throne . Throne pitched the idea to Gene Roddenberry . ( ) " Warrior ' s World " . Story outlines by Stephen Kandel , dated , , and . The outline was based on a story idea featured in Roddenberry ' s original series proposal , entitled " Camelot Revisited " , and dealt with an alien civilization ( described as sort of a " modern - day Roman Empire " ) , based on chivalry and a strict honor code , against which the smallest breach results in serious consequences . Roddenberry thought this was an episode full of action - adventure , but it would be too expensive to produce , and assigned Kandel to develop another of his story ideas , " The Women " , which ended up as . ( " " , pp . 69 - 70 ) A similar story concept ended up as . A modern - day Roman Empire was featured in . " The Web of Death " . " The Web of Death " was an undeveloped story outline , written by William Shatner in . The four - page outline was dated . The " Enterprise " discovers its sister ship , the missing USS " Momentous " near planet Urus III , trapped in the cocoon of a giant insect . The creature also begins to cover the " Enterprise " in the same white substance , without much means of escape . Finally , Kirk and the crew manage to distract the creature into attacking the " dead " " Momentous " , and rescue its crew and themselves . The outline was written before DeForest Kelley was cast as Doctor McCoy and the ship ' s doctor remains unnamed throughout it . In a " TV Guide " article , Gene Roddenberry mentioned that Shatner delivered him a story outline written by him , and that he found it quite good , having a " good flow " , despite his fears of it being terrible . The story was unproduced , though , probably because the series ' budget couldn ' t allow the special effects it would have needed . " The Well of Death " . " The Well of Death " was an abandoned " Star Trek " episode . ( )
