The Enterprise takes on a passenger, [[BlatantLies being that they are commonly in the habit of ferrying civilians]]. The boy is Charlie, an orphan with a MysteriousPast and [[NoSocialSkills really bad social skills.]] The people dropping him off seem in quite a hurry to leave.

Charlie becomes infatuated with Yeoman Rand, [[StalkerWithACrush stalking her]] and delivering presents she doesn't want. In the rec room we get to see Spock and Uhura make [[TheCastShowoff music]] together, which annoys Charlie because it distracts everyone (and especially Yeomand Rand) from him.

The ship Charlie arrived on blows up mid-transmission, with Charlie making a snide remark. Everyone is somewhat concerned, especially as odd things continue to happen upon the ship. For instance, Charlie loses chess and causes the chess pieces to melt. Nobody connects this to him (yet). Kirk is given the responsibility of talking to the boy and attempting to explain how to be normal.

Which he does by teaching him to [[ShirtlessScene wrestle]]. (Obviously.) When Kirk’s training partner laughs at Charlie, Charlie makes him disappear. Kirk is upset and orders him to his quarters, where he goes after making several threats. Charlie goes on a rampage when Kirk refuses bring him to the human colony he was planning on going to. The aliens that taught Charlie his powers appear to take him back, apologizing for the damage he's caused. He is brought back to live with them and the people that were attacked are [[ResetButton brought back to normal]].

!!Tropes

* AlasPoorVillain: Charlie doesn't want to go back with the Thasians, as they aren't physically real like Kirk or Rand. Kirk evens argues for a chance for Charlie to stay if he can be rehabilitated. But the Thasians point out they can't undo the talents they'd given Charlie to survive on their world. Charlie begs to stay... stay.... stay.........
* TheBlank: Charlie [[NightmareFuel erases several]] random crew members' faces while having a tantrum.
* TheCastShowoff: Creator/NichelleNichols. The musical rec room scene was entirely unnecessary, but entertaining.
* CharacterizationMarchesOn: Spock is smiling throughout Uhura's performance serenading him, merrily strumming along on his Vulcan lyre without so much as a quip or a sarcastic comment when she's finished. This is unquestionably the most laid-back we ever see Spock (without mind-altering devices being at work), and rings ''very'' false for him - contrast Spock and Uhura interacting the previous week in "The Man Trap".
* {{Chiaroscuro}}: In the gym when Kirk and Charlie are facing off, the lighting somehow changes mid-scene to make both Charlie and Kirk appear as though they are in a typical FilmNoir scene with venetian blinds. Also, their eye areas are highlighted to emphasize the drama and tension.
* CreatorCameo: Creator/GeneRoddenberry provides the voice of the Galley Chief amazed at the appearance of real turkeys.
* DeathGlare: Charlie has one using his powers. Kirk gives him one of his own after he breaks Spock's legs.
* DisconnectedByDeath: The ''Antares''
* DisproportionateRetribution: Charlie makes a crewmember in the gym disappear because he laughed at Charlie getting put on his ass by Kirk. A gaggle of anonymous crewmembers are [[BodyHorror rendered]] [[TheBlank faceless]] because they just happened to be laughing when Charlie stormed past. One female crewmember is turned into a lizard after expressing genuine concern for him. And Charlie wonders why nobody likes him.
* {{Expy}}:
** Many have compared Charlie to Anthony Fremont from ''Series/TheTwilightZone'' episode ''ItsAGoodLife''.
** Also to Valentine Smith from the novel ''Literature/StrangerInAStrangeLand''.
** Some may have noticed the title "Charlie X" and a connection to [[XMen a certain Charles Xavier]]. The debut of the comic book ''X-Men'' does predate this episode by three years but Professor X (who rarely if ever goes by "Charlie") is of course a mature man with telepathic (not telekinetic) powers that he only uses for the good of mankind. Also, at the time of this episode, the X-Men were one of the more obscure Marvel titles. It's most probable that any similarities were coincidental.
* ExplosiveInstrumentation: The communication console emits a shower of sparks and burns Uhura's hand. Justified in this case because it's Charlie using his powers to prevent communications with anyone outside the ship; Uhura states that there wouldn't normally be any reason for it to do that.
* GaussianGirl:
** Yeoman Rand gets the fuzzy treatment in all her close-ups (and not just the ones that are representing the infatuated Charlie's point of view).
** So, for some reason, does William Shatner.
* HisNameIs: The ''Antares'' tries to contact the ''Enterprise'' to warn them about Charlie (presumably after they felt they were a safe distance away), but Charlie destroys their ship, trying to pass it off as being a result of the ship being poorly built. Nobody buys it at this point.
* KilledMidSentence: The entire crew of the ''Antares''.
* PsychicPowers: Charlie can do lots of things, including transmogrification and making people involuntarily recite poetry.
* PsychopathicManChild[=/=]TeensAreMonsters: Charlie, with his ability to make people vanish.
* RedShirt: The one guy in the gym that laughs at Charlie. Charlie starts his rampage by making him disappear. Interestingly, he's wearing a red dogi. Other crewmembers of all uniform colors suffer in some way or another for offenses both great and small.
* ResetButton: The Thasians undo everything Charlie did on the ''Enterprise'', [[SubvertedTrope but are unable to do anything]] for the crew of the ''Antares'', who were killed by a warp core breach (caused by Charlie) rather than merely being transformed or disappeared.
* NoSocialSkills: Charlie has insufferably poor social skills.
* ReplacementGoldfish: Rand attempts to invoke this by setting Charlie up with a cute blonde crewmember closer to his age, but Charlie is utterly disinterested.
* SignificantReferenceDate: The episode was initially intended to air around Thanksgiving, hence the turkeys reference. However it ended up airing earlier due to it being the only completed episode at the time.
* SpiritualAntithesis: The episode can be seen as an antithesis of Robert A. Heinlein's novel ''StrangerInAStrangeLand'', which was published just five years before that episode aired. The plots of both works are essentially the same: an orphaned young man with nigh-omnipotent psychic powers is forced to adjust to human society after living his entire life among aliens, and finds himself entranced by the mysteries of human women. But while Heinlein's Valentine Michael Smith is a blissfully innocent figure who tries to use his powers to rid the human race of everything holding it back, ''Star Trek'''s Charlie Evans is a chillingly amoral figure whose alien upbringing leaves him incapable of using his powers responsibly. While Mike ends up successfully founding his own religion and social movement, Charlie is forcibly banished from human society for life.
* StalkingIsLove: That's what Charlie thinks, anyway.
* TheStoic: Spock doesn't think having his legs broken is worthy of mention until Kirk asks him to stand up.
* SufficientlyAdvancedAliens: The Thasians, who put everything right - except for the fate of the ''Antares'' - in about two minutes.
* TheTalk: Charlie's social awkwardness around girls is bad enough that Bones decides the boy needs to learn the rules. So he convinces Kirk to give it. And [[AnythingThatMoves Kirk]], of all people, gets too embarrassed to give it straight at all.
--> '''Kirk:''' There's no right way to hit a woman.
* UnnecessaryCombatRoll: Kirk demonstrates it for Charlie, and insists it's important when Charlie just wants to learn how to fight. Justified because Kirk is actually showing him how to fall safely when hit, which is just as important as being able to return the blow.
* VictoriasSecretCompartment: Charlie shows Yeoman Rand a "card trick" in which he tosses a card aside and makes it reappear down the front of her low-cut uniform. She's understandably startled and perhaps annoyed, given that the crew doesn't yet know about Charlie's powers and she can only assume that he pulled [[GettingCrapPastTheRadar a rather naughty bit of sleight-of-hand]].
* WildChild: Everyone assumed Charlie took care of himself from a very early age, explaining his horrible social conduct. Well, he did indeed have no ''human'' contact, so that does basically explain it.
* WoobieDestroyerOfWorlds: Charlie has NoSocialSkills, desperately wants to be liked and have friends, and has [[DisproportionateRetribution no sense of proportion]] when people don't treat him the way he wishes them to. Oh, and he is omnipotent. Picture a corporeal version of [[Series/StarTrekTheNextGeneration Q]] with NoSenseOfHumor and you have Charlie in a nutshell. The result is a maladjusted teenager who everyone is afraid of, who tries to make people like him by [[DramaticallyMissingThePoint punishing them whenever they make him unhappy.]]
