"The Next Cage" - Captain April is caged like an animal, and offered a mate. This was adapted into "
The Cage".
"The Day Charlie Became God" - A normal man accidentally gains infinite powers. It was adapted into "
Where No Man Has Gone Before" and "
Charlie X".
"President Capone" - A "parallel world" set on a
Chicago where Al Capone won the
presidency. This outline was the basis of "
A Piece of the Action", and went through several versions (including
George Clayton Johnson's treatment, "Chicago II") before the actual episode was developed.

"To Skin a Tyrannosaurus" - A modern man is reduced to stone-age level. This concept later appeared in
TOS: "
All Our Yesterdays",
TNG: "
Genesis" and
ENT: "
Extinction".
"The Women" - Some "hanky-panky" occurs when escorting a cargo ship of women to a deep space colony. This outline was the basis of "
Mudd's Women". Also, vaguely similar to
TNG: "
The Perfect Mate".
"The Coming" - A parable about an alien condemned to crucifixion and his dignity around the subject. The idea of a religion parallel to early
Christianity was used in "
Bread and Circuses". The plot of
TNG: "
Transfigurations" is similar.
"The Perfect World" - The SS
Yorktown lands on a supposed "perfect world," which appears similar to Earth ca.
1964. Only later do they realize that it is ruled by an authoritarian, Big Brother type; vaguely similar to "
The Return of the Archons".
"Mr. Socrates" - The SS
Yorktown discovers a planet which duplicates famous Humans, and then forces them into gladiatorial combat. This concept was used in
TOS: "
The Savage Curtain".
"The Stranger" - A "strange" alien intelligence begins to take over the minds of key crewmembers, in an attempt to fight a rival civilization. While similar to "
Day of the Dove", this story much more closely resembles the later
TNG and
DS9 story concepts for "
Conundrum" and "
Dramatis Personae".
"
The Man Trap" - The crew lands on a seemingly harmless planet, and begin to see apparitions. Eventually, they find that their wishes are being fulfilled in deadly ways. Despite the title, this story line had more in common with "
Shore Leave" than with the episode of the same name.
Camelot Revisited - On Hermes II, a modern society exists, yet they contain many medieval characteristics, such as knighthood; vaguely similar to
TNG: "
Qpid" and
VOY: "
Heroes and Demons".
"100 A.B." - An exploration of a parallel world a hundred years after an
atomic holocaust. The
Enterprise visited a post-atomic war civilization in "
The Cage". One of the three story drafts written by Roddenberry for the second pilot, "
The Omega Glory" was based on 100 A.B., and by the end of the second season of TOS, "The Omega Glory" had been written by Roddenberry into a series episode.
"Kentucky, Kentucky" - An Earth colony in the
Sirius group is reduced to fighting Viking-like savages in a "frontier" like community. The savage Klingons eventually appeared in "
Errand of Mercy", where they invaded a primitive frontier community.
"Reason" - The crew visit the Isaac IV group, where they discover a group of sentient robots. Shares similarities with "
I, Mudd".
"Reason II" - The story of the last Human survivors of the Isaac IV group, trying to take back control over the robots; similar to "
I, Mudd".
"A Matter of Choice" - A world where the natives have the power to relive any portion of their lives over again. The implications of such a concept are explored, albeit in a radically different way, by
TNG: "
Tapestry".
"The Radiant One" - A love story with a woman from a "Garden of
Eden" planet, except, because of her body chemistry, anyone who becomes her lover will die. Similar to "
That Which Survives" in plot. Also, thematically similar to "
The Way to Eden" in that death awaits those who find the Garden of Eden.
"The Trader" - The crew visit the oriental planet Satunii, that is strangely similar to the court of
Genghis Khan. Though the plot itself was not used, Genghis Khan did appear in the series, in "
The Savage Curtain". The notion of a rogue space traveler setting himself up as a leader over a world's natives appears in "
I, Mudd", "
Bread and Circuses", "
Patterns of Force", and "
The Omega Glory"
"A Question of Cannibalism" - The crew discovers that the colonists on
Regulus are actually herding sentient beings, and face angry settlers when trying to free the "cattle." The idea of colonists accidentally destroying sentient beings is re-used in "
The Devil in the Dark" and "
Home Soil". Also, the idea of sentient beings used as a commodity by others appears in
DS9: "
Captive Pursuit". Roddenberry wanted to use this story outline as the basis of the first
Star Trek feature film, when he approached
Paramount with such an idea as early as
1973.
Herb Solow commented, "
Gene's story premise would have been rewritten, because it did not foreshadow an enjoyable night at the movies." (
Inside Star Trek: The Real Story, pp. 420-421)
"The Mirror" - The
Yorktown discovers a duplicate
Yorktown. Now they have to decide whether or not to destroy their counterparts. Somewhat similar to "
Mirror, Mirror" and "
The Enemy Within". A similar concept was also used in
VOY: "
Deadlock".
"Torx" - A strange alien being "devours" intelligence, and is headed straight for Earth; somewhat similar in concept to "
The Changeling" and
Star Trek: The Motion Picture.
"The Pet Shop" - A world similar to
St. Louis,
1910, except women are the masters and men are women's pets. The concept was revisited much later in
TNG: "
Angel One" as well as in Roddenberry's 1974 pilot
Planet Earth and a similar idea, regarding
Orion slave girls, was established in
ENT: "
Bound".
"Kongo" - A planet where the "Ole Plantation Days" still occur, yet the racial roles are reversed. Worse yet, the crew find themselves stranded on the planet as runaways. This idea was later developed by
Barry Trivers as "Portrait in Black and White". Although multiple attempts were made to create the story work, it never got into a suitable form for the screen. According to
David Gerrold's book
The World of Star Trek,
DeForest Kelley in particular hoped to see a story episode where McCoy and Uhura become stranded on such a planet.
NBC program manager
Stan Robertson dismissed the idea, calling it "far from the accepted
Star Trek norm". (
Inside Star Trek: The Real Story,
These Are the Voyages: TOS Season One)
"The Venus Planet" - The crew discover a planet of women. The men become increasingly attracted to the women, and almost too late do they realize that there are no more men on the planet. The story bears a striking resemblance to both
TAS: "
The Lorelei Signal" and
VOY: "
Favorite Son".
"Infection" - A female crew member discovers that she may be pregnant with an alien larva. Likely formed the basis for the
Star Trek: Phase II premise "The Child", which was itself then recycled into
TNG: "
The Child".
