->''"Listen - what I said before, John? I meant it. I don't have ''friends''. I've just got one."''
-->-- '''Franchise/SherlockHolmes''' to [[TheWatson John Watson]], ''Series/{{Sherlock}}''

Some characters have TrueCompanions. Some characters have social circles (however {{limited|SocialCircle}} they may be). Alice doesn't have that. Alice has Bob. ''Just'' Bob.

There are two possible ([[CharacterDepth though not mutually exclusive]]) variations on the Alice character here:
# Alice is [[ShrinkingViolet shy]] or a bit of a [[{{Cloudcuckoolander}} misfit,]] but ultimately a [[NiceGuy nice person.]] Bob is the only one to take the time to get to know her and realize that she's actually pretty cool.
# Alice is a {{Jerkass}} or otherwise hard to get along with. Bob is the only one willing to put up with her shenanigans.

There are also two variations on the Bob character:
# Bob [[LonelyTogether is a fellow misfit who was drawn to Alice because neither of them had any other friends]].
# Bob is the one with all the [[TheSocialExpert social skills]], and may try to help Alice make more friends and/or [[CloudcuckoolandersMinder smooth over situations where her behavior has caused problems.]]

While Alice-1s often go along with Bob-1s and Alice-2s with Bob-2s, they can be mixed and matched: a shy Alice might have a social Bob who tries to draw her out of her shell, while a mean Alice might have a shy Bob who's stuck with her because he's lonely or doesn't have the nerve to ditch her. Or both.

In many stories, an Only Friend doesn't stay that way for long: a nice Alice will usually have learned to make friends by the end of the story, while a mean Alice will often find Bob finally getting fed up and leaving her.

Compare with LivingEmotionalCrutch, which might be at play in an extreme form of this trope. Compare BestFriend, where a character has other friends, but one of them is the closest and most trusted.


[[folder: Anime and Manga ]]
* Applies to Alice in ''Manga/{{Aria}}'' to a degree. Since she's extremely unsociable and cold towards anyone, it's really only Akari and Aika that she can truly call her friends. She insists that they are different from all the other girls, although this is mainly because of her warped perception of the people around her - She thinks she's disliked and envied for being talented, when in reality most people admire her.
* In ''Manga/AzumangaDaioh'', Nyamo is [[{{Jerkass}} Yukari's]] only friend at the start of the series. She later bonds with [[IntergenerationalFriendship several of her students]] but they're obviously not as close as she is to Nyamo.
* In ''LightNovel/BakaAndTestSummonTheBeasts'', [[spoiler: Yuuji the first person who treated Shouko as an equal and didn't fear her [[TheOjou because of her wealth and high social status]]. In fact, this is one of the reasons why she's {{Yandere}} for him.]]
* ''Manga/{{Beelzebub}}'':
** Furuichi is Oga's one and only friend, due to the latter's inability to stop fighting and rough personality.
** Himekawa's only friend was Kugayama, until he betrayed him, which really screwed him up and left him unable to heal until he met Oga. [[spoiler:That said friend was also in reality a chick and in love with him did not help.]]
* In ''Manga/BokuraNoHentai'', Akane was Marika's only friend from pre-k to elementary. Marika was bullied by the other kids growing up for being [[{{transsexual}} too girly]].
* ''Manga/BokuNoHeroAcademia'':
** While his classmates respect him, nobody actually likes Bakugou, except for Kirishima who plays this for him. He is the only one that can handle the boy's explosive behaviour, eventually developing into his MoralityPet.
** A variation happens with Midoriya towards Todoroki. While Todoroki is by no means isolated from the rest of the class, Midoriya is still the one he is closest to, and he rarely ever speaks to other people.
* In ''Anime/CodeGeass'' [[spoiler: season 2 Lelouch has lost his love interest, his sister, his best friend, and has a confusing relationship with the rest of his friends. The only person who truly understands and trusts him is CC. Then she loses all her memories and personality. Because of this Lelouch takes over the pre-episode speech for the next few episodes, and the bitterness and anger in his voice just tells all.]]
* ''Manga/DeathNote'':
** L claims that Light is his "first ever friend". According to WordOfGod, though, he's lying; he knows that even Light isn't really his friend.
** Also, [[ChildhoodFriends Matt and Mello]] play this role (for real) to each other.
* ''Anime/DragonBallZ'':
** After saving Gohan's life by jumping in the way of an energy blast, the dying Piccolo admits that the kid he abducted and put through TrainingFromHell is the only friend he's ever had. Granted, after his revival, this is no longer the case as he ends up becoming good friends with the Z-Fighters or at least Goku, Krillin and some of the others.
** Hercule/Mr. Satan tearfully admits that despite his popularity, Fat Buu is his only real friend. He later becomes good friends with the Z-Fighters.
* ''Manga/FairyTail'': Zeref had [[spoiler:Mavis. She was the only one to ever see beyond his curse and empathize with his pain. After she herself fell under the same curse, she also became the only one that would ever be able to truly relate with him -- it was what ultimately caused their friendship to evolve into love. [[TheLostLenore Mavis's death]] is what drove Zeref over the deep end and finally [[ThenLetMeBeEvil succumb to being as evil]] as the rest of the world declared him to be]].
* In both the anime and LightNovel of ''LightNovel/FateZero'', Gilgamesh cites this as the reason [[spoiler: he refuses Rider's offer for them to join forces.]] Enkidu is the only friend he has ever had, and the only one he ever ''wants'' to have.
* From ''Manga/HanaNoNamae'', Mizushima Kei's only friend is his editor and biggest fan, Akiyama Shinichi, [[BlatantLies though Kei tries to claim that he hates Shinichi]].
* ''LightNovel/HaruhiSuzumiya'':
** {{Jerkass}} Haruhi Suzumiya notes with pride in ''Manga/TheVanishingOfNagatoYukiChan'' that only Kyon speaks to her informally. In the ''LightNovel/HaruhiSuzumiya'' series proper, Kyon's sister (that's all we know of her name) and Tsuruya are the only persons who are friendly towards Haruhi, without being burdened with Haruhi's secret.
** Shy Yuki Nagato (in either series) doesn't feel comfortable going to the library without Kyon.
* In ''LightNovel/HighSchoolDXD'', Ophis refers to [[spoiler: [[IntergenerationalFriendship the protagonist Issei]] as its one and only true friend.]]
* From the backstories of the girls in ''Manga/KOn'', it seems like before they met each other and became TrueCompanions, nearly all of them had only one friend to depend on. Mugi (Alice-1) and Sumire (Bob-1) literally had no one else except each other growing up, because both of them were home-schooled and heavily sheltered. [[TheDitz Ditzy]] Yui (Alice-1) doesn't seem to have had any other friends before high school except Nodoka (Bob-2), and Mio (Alice-1) was so shy and quiet as a child that only Ritsu (Bob-2) ever managed to break through her shell.
* In ''Anime/MaiHime'', at the start of the series, Shizuru is Natsuki's only friend. Shizuru is a Bob-2 as a fairly popular individual on campus, while Natsuki is somewhere between Alice-1 and Alice-2, as she's given up on the idea of getting close to others.
* Koyuki was Ginta's only friend at the beginning of ''Manga/{{MAR}}''. Weirdly enough, it's implied that she's just a friendly classmate in the opening, but as we see more and more flashbacks, it turns out she's been his only friend for a long time.
* ''Anime/PuellaMagiMadokaMagica'':
** Madoka is [[spoiler:Homura's]] only friend in most timelines. [[spoiler:[[LivingEmotionalCrutch It's the main reason Homura keeps going]]]]. It gets a little darker than that [[DarkerAndEdgier (naturally).]] She was friends with all of the girls before but [[spoiler:with each new timeline]] she got closer to the edge of insanity and stopped caring about them altogether and admits she doesn't "give a damn" if [[spoiler:some of them die along the way to save Madoka.]] It could be assumed that the reason she never stopped caring about Madoka is because in [[spoiler:every timeline]] Madoka is literally the only one who never turned on her and was always nice to her no matter the situation they were in, unlike the other girls who would call her a liar and sometimes attempt to kill her in a bout of depression. Sayaka in particular could be very cruel to her.
--> [[spoiler: '''Homura:''' "Madoka, my only friendů if it's for your sake I don't mind being trapped in this endless maze forever."]]
** Which is ironic considering that [[spoiler: Madoka happens to be the only person that stands behind Sayaka as well. For the same reasons as Homura. When Sayaka, in a moment of grief and rage, pushes Madoka away... [[MyGodWhatHaveIDone She is freaking out about it soon after.]] And the fact that [[LivingEmotionalCrutch she push away the only person willing to support her]], happens to be one of the factors that makes Sayaka [[DespairEventHorizon come to the conclusion that everything is hopeless]].]]
** This seems to be a recurring element of the series. It's shown in ''The Different Story'' that Mami and Kyouko once had this relationship, and them breaking it off was a major factor in Mami's possessive attitude at the time of the series, and why Kyouko was so desperate to get close to Sayaka. In ''[[Anime/PuellaMagiMadokaMagicaTheMovieRebellion Rebellion,]]'' it's revealed that Mami's greatest wish was to have a friend, hence the presence of Bebe/Charlotte[[spoiler:/Nagisa]], who acted as this toward her.
** Then there's [[Manga/PuellaMagiOrikoMagica Oriko and Kirika]], who take it all the way to LivingEmotionalCrutch territory on both ends.
* In ''Anime/TigerAndBunny'', [[IceKing Barnaby]] pushed people away for so long that he's [[FriendlessBackground never had a single friend in his life]] before Kotetsu came along, [[DefrostingIceQueen defrosted him like no one's business]], and became his HeterosexualLifePartner[=/=]LivingEmotionalCrutch.
* In ''Anime/LegendOfGalacticHeroes'', it can be assumed that this trope applies to Reinhard and Reuenthal, with Kircheis and Mittermeier respectively. The latter two are sociable enough to at least be ''able'' to have friends aside from them, but Reinhard is far too busy realizing his ambition to befriend anyone ''but'' Kircheis, and Reuenthal's trainwreck of a psyche doesn't let him get close to anyone aside of Mittermeier who becomes his LivingEmotionalCrutch. Reinhard does open up a bit to others as the story goes on, most notably Hilda, Mittermeier and Emil.
* In ''Manga/VinlandSaga'' Askeladd calls Bjorn his only friend [[spoiler:as he {{Mercy Kill}}s him from an infected gut wound]]. Whether it was genuinely meant is never made clear.
* For several volumes of ''Manga/WanderingSon'' Kanako was Saori's only friend. Saori had a FriendlessBackground until the start of the series due to having NoSocialSkills and disliking the other children. At the start she started befriending Nitori, which also made her friends with Kanako, Mako, and Takatsuki. The LoveTriangle between her, Nitori, and Takatsuki however ruined their friendship and Saori TookALevelInJerkass. She only hanged around Kanako for most of middle school but eventually she rekindled her old friendships. [[spoiler:In high school Takatsuki is her only friend, as she's become distant with the others due to being in different schools]].
* ''Anime/YuriOnIce'':
** Episode 10 reveals that Christophe is this to Victor. During his years dedicating his life to his career, Victor had almost no time to actually create interpersonal relationships, but since Christophe has been competing with him from the start, they eventually became closer.
** Otabek is this to Yuri Plisetsky. Otabek is explicitly stated to be Yuri's first friend.
* Tetsuo from ''Manga/{{Yuureitou}}'' mentions that Amano was his first friend. Growing up he [[AllOfTheOtherReindeer stood out]] and didn't get along much with the girls at his orphanage. As an adult he was very aloof until allying with Amano. [[spoiler:In the end they have a RelationshipUpgrade]].

[[folder: Comics]]
* Helena Bertinelli, aka the ComicBook/{{Huntress}}, had only one friend, the ComicBook/BlackCanary. This was primarily because Huntress was a borderline sociopathic misanthropic loner, so she was an Alice-2. Eventually, Huntress seemed to be forming friendships with a couple of other characters, notably Renee Montoya (the new Question), and Oracle. All this, of course, was in the old DCU; now we're back to Helena Wayne.
* {{Franchise/Batman}}, when not the PapaWolf for his collection of sidekicks, is often portrayed this way, with {{Franchise/Superman}} as his only friend. In these cases, it's implied that Batman is friends with Superman because he's NighInvulnerable and Batman is therefore unlikely to lose him, while Superman is friendly because Batman understands having the weight of the world on his shoulders and doesn't hero worship Supes.
* ''ComicBook/TransformersMoreThanMeetsTheEye'': Brainstorm is a quirky MadScientist with a LackOfEmpathy, a penchant for making weapons so utterly unethical he's built up a reputation for them, and a HeroicComedicSociopath streak. Chromedome is his only friend, a fact he acknowledges to have Brainstorm do him a few favors. Brainstorm actually cares for Chromedome, and tries to [[spoiler: talk him out of erasing all the memories of his now dead lover Rewind to spare himself the pain]]. He admits to seeing him do it 3 times before, and is concerned about him, worrying about his mental health and his lack of coping abilities. [[spoiler: He gives Chromedome Rewind's last message, and leaves him to do what Chromedome thinks is best.]]
* In ''ComicBook/{{Watchmen}}'', Rorschach's only friend is Nite-Owl, and even his patience is really tested with Rorschach's personal habits and extreme opinions.
* ''Comicbook/LokiAgentOfAsgard'':
** Loki's new MuggleBestFriend is Verity Willis. Loki is Loki, and thus a certifiable jerkass and ConsummateLiar. Verity is a fellow misfit for the opposite reason: she's a LivingLieDetector with [[BlessedWithSuck no way to switch it off]].
** In issue 11, it turns out this went both ways: [[spoiler: after the evil future Loki drops one bombshell too many on her, Verity can't handle the betrayal and walks out. King Loki asks his younger self if he ever noticed her lack of other friends - and then cracks up. "I kid."]]
** And then it becomes heartwarming / tear jerking in issue 13. [[spoiler:Loki when faced with a SadisticChoice between IDieFree and ChronicVillainy they TakeAThirdOption which is basically LossOfIdentity, with this friendship chosen to become as a core part of the new.]]

* In ''Fanfic/ATriangleInTheStars'', Bill comes to consider [[spoiler: Steven]] this, since he overall thinks [[spoiler: Kryptos and Hectorgon]] only befriended him out of pity, and the rest only see him as a boss.
* In ''[[Fanfic/DeliverUsFromEvilSeries Mortality]]'', Holmes and Watson are this [[LivingEmotionalCrutch for each other.]]
* In the ''Literature/{{Kieshara}}'' fic ''[[https://www.fanfiction.net/s/7980541/2/Gryphontears Gryphontears]]'', the hybrid shapeshifter Agrippina is [[FantasticRacism discriminated against]] and has no friends except for Riadne.
-->Most falcons my age refused to be seen near me- if I entered a room, they would leave it. Aside from Riadne, the peregrine in front of me, I had no friends. And because of me, neither did Riadne.
* ''FanFic/VariationModification:'' Dave becomes Karkat's only friend after saving him from a gang of bullies.
* In ''Fanfic/NecessaryToWin'', Sumire is Teru's only friend, as perhaps the only person who knows her from before her personality was altered forever and she became colder, more distant and estranged from her younger sister, {{Manga/Saki}}, making Teru something of an Alice-2. Sumire is a Bob-1, who was, originally, the Alice-1 to Teru's Bob-2, since Teru was the one who reached out to her, back when she [[UsedToBeMoreSocial was more social]].
* In ''FanFic/ACharmedLife'' Light feels this way about Ryuk.
* In ''FanFic/DespairsLastResort'', it's made clear that Chiyo is Kumiko's only friend since they were kids. [[spoiler: After Chiyo dies, Kumiko begins to make friends with the others.]]
* ''FanFic/{{Shatterheart}}'', Kurogane is initially [[spoiler: Real!]]Syaoran's only friend since the rest of the group avoided him or hated him.
* Princess and Bubbles become this to each other in the ''Crimson and White'' portion of ''WesternAnimation/ThePowerpuffGirls'' fanfic ''FanFic/{{Ladder}}''. Princess is too untrustworthy of others to have friends and Bubbles isn't close to the other children. When they start becoming friends Princess at first tries to act like they're just spending time together, not acting like friends, but she later accepts Bubbles as her best friend. [[spoiler:This only makes Bubbles murdering her later all the more tragic.]]
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''FanFic/{{Asylum}}'', Rainbow Dash and Fluttershy are each others only friends [[spoiler:until Twilight begins befriending them]]. Fluttershy has extreme social anxiety and shuts down around most ponies, while Dash is very aggressive and keeps everyone at arms length. The two go back years [[spoiler:because they were foster siblings]].
* In ''FanFic/TheBridge'' we have Xenilla and Destroyah. While they don't use the term "friend" to describe each other, they are the only kaiju truly loyal to each other and will charge in to help the other when danger calls.
* Lydia is this for [[Film/{{Beetlejuice}} Betelgeuse]] in ''Fanfic/SayItThrice''. He rants at WesternAnimation/DannyPhantom that this is the reason he calls her "his girl" - she's his only friend and that makes her ''his''.
* In the ''WesternAnimation/{{WITCH}}'' fanfic ''Fanfic/{{Ripples}}'', Will -- TrappedInThePast as [[FountainOfYouth a child]] and operating under the SecretIdentity of "Van Rivers" -- becomes this to a young Prince Phobos, something that everyone acknowledges.

[[folder: Film]]
* Jenny to Film/ForrestGump in their youth; Bubba during the war; Lt. Dan for a time after the war.
* ''Film/BackToTheFuture'': Marty [=McFly=] is all Doc has, except for his dog. Doc is an Alice-1, a decent and loyal man who happens to have the reputation of being a MadScientist. Marty himself is implied to be part Bob-1 and Bob-2, as he is a CoolLoser who nonetheless knows enough about making friends to have the fellow members of his garage band.
* Dante to Randal in ''Film/{{Clerks}}'' and ''Film/ClerksII'', which is why Randal is so rattled by the thought of Dante leaving in the second one.
-->'''Randal:''' You think I wanna start making friends at my age? Christ, [[TheFriendNobodyLikes who would want me as their friend]]?

* ''Film/SherlockHolmes'' and ''Film/SherlockHolmesAGameOfShadows'': Holmes and Watson are most likely this [[LivingEmotionalCrutch for each other.]]
* ''Film/XMenFilmSeries'':
** ''Film/XMenFirstClass'':
*** Near the beginning of the film, Raven points out to Charles that she is his only friend. Presumably an affable fellow like Xavier would have numerous acquaintances, but his sister figure is the sole person he fully trusts.
*** Charles becomes this to Erik because the latter has spent his life on the hunt. Lehnsherr hasn't met anyone who could empathize with him since his mother died.
** ''Film/TheWolverine'': Yukio was adopted from the streets with the specific task of serving as this to a young Mariko. Mariko, however, always saw her more as a sister.
** ''Film/XMenDaysOfFuturePast'': After Past Xavier isolates himself from the outside world due to his severe depression, Hank becomes his sole companion. [=McCoy=] also doesn't seem to have a social circle, as he has taken it upon himself to be Charles' caretaker, which appears to be something of a full-time job.
* Chaitanya in ''Film/BadWords'' doesn't have any friends due to being a bit of a nerd (he initially thought that being a good speller would get him friends). He takes his friendship with Guy very seriously, so much so that [[spoiler: he's willing to lose the spelling bee on purpose to prove that the friendship was real.]]
* ''WesternAnimation/TheBookOfLife'':
** Chuy to Maria when she was studying abroad for 10 years.
** La Muerte is heavily implied to be this to her husband, Xibalba. The realm he rules over has souls who just rot into ashes.
* ''Film/TheImitationGame'': Christopher was this to the young Alan Turing.
* Jason and Derek in ''Film/BackToSchool'', at least at first. When Jason's trying to explain to his dad why he wants to drop out, he says:
-->I don't fit in, you know? I got one friend...Derek. He's got no friends.
* ''Film/ShaunOfTheDead'' actually starts off with [[TheEveryman Shaun]] saying he's [[{{Jerkass}} Ed's]] only friend, which is why Ed ends up coming to most of Shaun and [[LoveInterest Liz's]] dates.

[[folder: Literature ]]
* In ''Literature/DragonQueen'', since Sajag is a dwarf living among humans, and is normally pretty quiet, Trava is his only friend. And Sajag starts as Trava's best friend, but quickly becomes her only friend.
* In ''Literature/AChristmasCarol'', Jacob Marley was Ebeneezer Scrooge's only friend and vice-versa until his death. It's telling that, although they were both unfeeling, ruthless capitalists, they remained business partners almost their entire adult lives, and neither ever tried to effect a takeover or muscle out the other.
* From the ''Literature/HarryPotter'' Series:
** In ''Literature/HarryPotterAndThePhilosophersStone'', Harry and Ron are each other's only friend. Hermione begins the year friendless and isn't friends with Harry and Ron until midway through the book.
** It's hinted that Ron's younger sister Ginny was this to Luna Lovegood, as one of the few people who didn't straightforwardly reject her for being odd.
** From what we see of Snape's memories, it's made clear that his only real friend was [[spoiler: Harry's mother, Lily,]] until she ended the friendship at the end of their fifth year [[spoiler: because he was becoming a bigger jerk and delving into the dark arts with his Death Eater buddies, but the final drop came when ''he called her a racist epithet when she was trying to help him''.]] In his adult life, if he has a friend, it's [[spoiler:Dumbledore; he's certainly the only person who truly knows and likes him.]]
* Literature/SherlockHolmes' idiosyncrasies and general lack of interest in other humans except as puzzles ensures that [[LivingEmotionalCrutch Watson is his entire social circle.]]
-->'''Watson''': That was surely the bell. Who could come to-night? Some friend of yours, perhaps?
-->'''Holmes''': Except yourself I have none. I do not encourage visitors.
** By "The Final Problem," Holmes appears to have some CharacterDevelopment, [[spoiler: writing in his note to Watson how his coming death will cause grief to Holmes' friends]], and in "The Adventure of the Six Napoleons" enjoys the regular visits of Inspector Lestrade.
** Works in reverse too. Watson has very few friends and no surviving relatives. He does marry at the end of the second story, but is eventually widowed. So it's possible that [[LivingEmotionalCrutch Holmes is also one for Watson.]]
* John Cleaver from the ''Literature/IAmNotASerialKiller'' trilogy is friends with another social outcast Max in order to [[GenreSavvy try and avert]] falling into LonersAreFreaks. Despite his sociopathic nature, John makes other friends in [[Literature/MrMonster the]] [[Literature/IDontWantToKillYou sequels]] but is so focused on his quest he pretty much still only has one friend at a time, leaving poor Max friendless.
* In ''Film/ThePrincessBride'', Fezzik and Inigo are each other's only friend (at least until they team up with Westley and Buttercup). However, as these things go they both seem fairly easy to get along with, so it probably has more to do with that they're busy doing Vizzini's bidding, Inigo is obsessed with avenging his father, Fezzik is used to being an outcast, and it emphasizes their HeterosexualLifePartners relationship.
* Francis is Michael's only friend in ''Literature/TheTraitorGame''. Not the other way round, though; there are mentions of Francis's other friends. They're both a mix of the two types. Michael don't easily make friends (and when he ''does'' form a friendship, [[spoiler:he manages to break it]]), but [[FreudianExcuse that's only because he was bullied at his previous school]]. And while Francis is a NiceGuy and a CoolLoser, he's also a bit of a misfit - possibly because of his friendship with Michael and [[spoiler:his homosexuality]] - and he too sees Evgard as an escape from everything else.
* Before the main events of ''Literature/TheHungerGames'', Katniss's only friend was Gale, unless you counted the sort-of-friendship she had with the mayor's daughter, Madge, as they both were loners at school and therefore got paired up together in activities by default.
* In ''Literature/TheMortalInstruments'', Simon Lewis is the only mundane with whom Clary Fray is ever shown to interact.
* In ''Literature/WhyWeTookTheCar'', Tschick and Maik eventually become this for each other.
* Mannie is this to Mike at the beginning of ''TheMoonIsAHarshMistress''. His [[IJustWantToHaveFriends desire to make more friends]] is the main reason Mike becomes involved in the Lunar rebellion to begin with.

* Early on ''Series/InPlainSight'', Marshall and Mary proclaim each other to be this. Ultimately, it seems like their circles have expanded... by maybe one or two people each.
* In ''Series/PleaseLikeMe'', Josh's boyfriend Geoffrey admits that Josh is his best and only friend. Which Josh finds odd.
* [[Series/TheInspectorLynleyMysteries Thomas Lynley]] and Barbara Havers. He is her only true friend. Funny enough it also works in reverse - while Lynley does have one or two other close friends, he is nearly as difficult to work with as Havers is. They ultimately wind up as TrueCompanions, via [[OddCouple complementing each other surprisingly well]], presumed betrayal, a near drowning, and more tragedy than any two people should ever have to go through.

* In ''Series/PersonOfInterest'', [[BadassInANiceSuit Reese]] admits that [[MissionControl Finch]] is his only friend [[spoiler:while trying to save him from a kidnapper]].
* Most characters on ''Series/TeenWolf'':
** Scott and Stiles are the main example: They were [[{{HeterosexualLifePartners}} best friends]] prior to the series and have been since kindergarten according to WordOfGod. As awkward misfits they never had anyone but each other and their actors said the fact they're both missing a parent drew them together even more. Stiles seems perfectly happy with just having Scott and although Scott tries to make more friends, Stiles is [[{{SecretKeeper}} the only one he confides in]] about his werewolf powers and dealing with supernatural issues puts somewhat of a damper on them socializing with other students. Gradually averted as their [[{{TrueCompanions}} circle]] gradually extends to include other people in the know, including Scott's girlfriend Allison, her best friend Lydia, Alpha werewolf Derek, beta Isaac and new student kitsune Kira. Stiles' actor Creator/DylanOBrien [[{{LampShades}} lampshades]] this trope.
--> O'Brien: "And there's really nothing beyond that, it's just we met in the sandbox when we were four and we've been best friends ever since and we felt 'eh, no need to make any other friends, it doesn't matter.'"
** Jackson is a straight-up JerkJock, and the only person is actually nice to is his StraightGay best friend Danny.
** Lydia (and Jackson's girlfriend) is the school's AlphaBitch, but NewTransferStudent Allison is the only person she's close with.
* In ''Series/StarTrekTheNextGeneration'' Q claims that in all the universe Picard is the closest thing to a friend he has. Apparently the Q Continuum from which Q comes from has become far too rigid, boring, and predictable for his tastes, and Picard is one of the few interesting things going on in the universe.
* ''Series/{{Merlin}}'': Both Gwaine and Arthur have said that Merlin is their only friend.
* Scully (Bob-2) and Mulder (Alice-1) of ''Series/TheXFiles''. Scully seems to have peripheral friendships that come up when convenient, but for the most part they are each others' only consistent, trusted friend.
* ''Series/{{BronBroen}}'' ends with Saga shouting at [[spoiler:Martin]], "How could you do this? You were the only friend I had!" [[ByTheBookCop It doesn't prevent her from arresting him, though.]]
* The early relationship between Leonard and Sheldon in ''Series/TheBigBangTheory'' where everyone else found him seriously hard work, Raj and Howard were reluctant to get any closer, and Penny hadn't adopted her TeamMom persona to the guys. Leonard had a lot of interpreting the wider world to do for his flatmate.
* Paris Geller of ''Series/GilmoreGirls'' considers Rory this. She's a JerkWithAHeartOfGold, but Rory is the only person who has the patience to sit through the "Jerk" side. According to Paris, everyone else leaves the room when she talks. However in high school Paris always hangs out with [[GirlPosse two girls]], even before befriending Rory, so this mostly applies when they are in college.
* In "Series/BuffyTheVampireSlayer", Spike considers Joyce this, but then is later replaced by Dawn [[spoiler:after Joyce's sudden death]]. This is later subverted after Dawn finds out that [[spoiler:Spike tried to rape Buffy]], then she cuts off their relationship.

* In ''ComicStrip/CalvinAndHobbes'', Hobbes doubles as both Calvin's ImaginaryFriend and his only friend.
* In ''ComicStrip/FoxTrot'', Marcus is basically Jason's only real friend. The only other peer he ever spends any time hanging out alone with is Eileen (on a few rare occasions), and his feelings towards her are so conflicted - partly because she's also an academic rival and partly because he's still convinced GirlsHaveCooties - that it's hard to call it a truly mutual friendship. This is acknowledged at the start of one storyline when Jason is asking his mother to go to a science camp for the summer and says Marcus is going, even calling him his only friend.
* In ''ComicStrip/{{Luann}}'', a number of supporting characters have one friend each. Brad and TJ are each other's only friend (where Brad is the Bob to TJ's Alice-2), Toni once had another female friend but has since stopped spending time with anyone except her fiance Brad (to the point where she had to ask his sister to be her Maid of Honor due to not knowing anyone else) and Quill had only Gunther. Until she received some CharacterDevelopment enabling her to grow closer to the main cast, even the resident AlphaBitch had only a single friend instead of the usual GirlPosse associated with the trope.

[[folder: Theatre ]]
* In ''Theatre/{{Chess}}'', Florence is Freddie's only friend, although by the end of the first act even she has gotten fed up with his {{Jerkass}} behavior and left him. (Which, given what we see of their interactions, is less surprising than the fact that [[NoAccountingForTaste she was with him in the first place]].)
* Albus Potter and Scorpius Malfoy are each other's only friend in ''Theatre/HarryPotterAndTheCursedChild'', as both of them are shunned (but for different reasons: Albus is viewed with suspicion as the only one in the legendary Potter family being sorted into the Slytherin House (all of the other Potter family members are Gryffindor House members) while Scorpius has the baggage of being born into an infamous Death Eater family -- the Malfoy family, in his case).
* A RunningGag in the one man play "Shylock" is that Tubal is Shylock's best friend - well, his only friend.
* In ''Theatre/{{Wicked}}'', [[TheSnarkKnight Elphaba]] is a mix of Alice-1 and Alice-2, while her only friend [[LovableLibby Glinda]] is a Bob-2.

[[folder: Video Games ]]
* In ''VisualNovel/TokimekiMemorial 2'', [[BrokenBird Kaori Yae]] starts this way, with Kaedeko Sakura being her only friend. That's because Kaori is hugely distrustful of others [[DarkAndTroubledPast due to a traumatic past experience]], and Kaedeko is the only person she feels innocent, straight and honest. By the end of her storyline, [[ShesBack when she'll solve her personal turmoils]], the male protagonist will be her other close friend and lover, and she'll have made a few other friends along the way.
* ''VideoGame/KingdomHeartsII'' gives us the scene of [[spoiler:Axel's]] death, where he tells Sora that Roxas was the only one he liked, and basically his only friend, though that wasn't really the case, since Xion was also his friend along with Roxas, though when [[spoiler:she "died", all memories of her disappeared.]]
* In ''VideoGame/GhostTrick'', [[spoiler:Sissel the Cat was Yomiel's only friend in the original version of the previous 10 years]]. This eventually changes, as [[spoiler:his fiancée doesn't commit suicide in the new timeline (however, the cat isn't his in this reality)]].
* In ''VideoGame/NoMoreHeroes'', Bishop Shidux is described as Travis Touchdown's only friend. [[spoiler: His murder by the the BigBad]] convinces Travis to reenter the assassin ranks in [[VideoGame/NoMoreHeroes2DesperateStruggle the sequel]].
* In Rockstar's ''VideoGame/{{Bully}}'', main character Jimmy Hopkins is shy guy Petey's only friend. Presumably this changes after the end of the game when [[spoiler:Jimmy convinces Dr. Crabblesnitch to make Pete the new head student at Bullworth.]]
* If Shepard is female and begins a romantic relationship with Garrus in ''VideoGame/MassEffect2'', Garrus tells her she's his only friend in the galaxy. Thane admits to Shepard that s/he's the first friend he's made in twenty years. Liara suggests this when she asks Shepard for patience on Illium, saying she doesn't have enough friends left to lose him/her.
* Due to his attitude problems, Barry Wheeler is VideoGame/AlanWake's only friend, if you don't count his wife. The point is brought up several times throughout the series, with the imaginary Barry from ''The Writer'', mentioning how pathetic it is that Wake's only real friend is his agent, and Alan admitting, through a manuscript page in ''American Nightmare'', that, while he doesn't make friends easily, he trusts Barry completely.
* ''Franchise/DragonAge''
** A female Warden can become this to Morrigan in ''VideoGame/DragonAgeOrigins''. It's stated outright in the "deleted scene" comic authored by [[WordOfGod David Gaider]].
--> '''Alistair:''' So you ''have'' friends?
--> '''Morrigan:''' Only one.
** In ''VideoGame/DragonAgeII'', Fenris can tell Hawke they're the only friend he's ever had before the final battle. In practice, he's on friendly terms with most of the party's [[DoesNotLikeMagic non-mages]] (and plays cards with Aveline's husband every week). Hawke is just the one he trusts enough to ''call'' them a friend.
** In ''VideoGame/DragonAgeInquisition'', a befriended Dorian who is not romanced by the Inquisitor [[spoiler:or Iron Bull]] will, at the victory party, refer to the Inquisitor as "my best and only friend." In the ''Trespasser'' DLC, he reiterates it, telling the Inquisitor that "you are my dearest, and perhaps only, friend."
* Elisabeth Blanctorche and [[spoiler: Ash Crimson]] have this kind of relationship in ''VideoGame/TheKingOfFighters''. So much that [[spoiler: Ash's big ass BatmanGambit (which included de-powering Chizuru and Iori, attacking Kyo, joining Those of the Past, antagonizing Elisabeth, manipulating everyone and ultimately ''getting himself {{ret gone}}d'']] was to keep Elisabeth safe.
* In ''VisualNovel/DanganRonpa'', this is how Ishimaru Kiyotaka views Oowada Mondo. Due to how strict he is and how much time he spends on studying and encouraging the rules and proper school behavior, Ishimaru never had a chance to make a single friend, even among the cast, until Mondo comes along. As a result, he suffers from a HeroicBSOD when [[spoiler: Mondo is revealed to be the murderer in Chapter 2 and is executed. [[BrokenPedestal So not only is his only friend dead, but he also killed someone, even if it was unintentional.]]]]
** In the sequel, ''VisualNovel/SuperDanganRonpa2'', Sonia Nevermind is this for Gundam Tanaka. Gundam rarely socializes with the other students when there isn't a problem, claiming that his only friends are his pets and that he doesn't need human companions. Not including the optional friendship he can have with Hinata, the only student he eventually befriends and shows respect to is [[NiceGirl Sonia]], who shares his interest in animals and occult things. She's also the only person who Gundam doesn't refer to with any sort of contempt or condescending attitude, and the only one he willingly hangs around and communicates with.
* In ''FateExtra'', this is Gilgamesh's stance on Enkidu. [[spoiler:Since Enkidu was originally a weapon whose life was "without worth", Gilgamesh proclaimed that Enkidu would be his only friend for all eternity, thus granting him an absolute and undiminishing value.]]
* Kratos from ''VideoGame/GodOfWar'' appears to only have one friend in the entire series who doesn't either die too quickly for him to develop any kind of bond with, betray him or get betrayed by him in Orkos from ''Ascension''.
** Well, Orkos and Pandora. Pandora has enough of an impact that he finally starts to take responsibility for his crimes and feel remorse.

* In VisualNovel/KatawaShoujo, Lilly is initially Hanako's only friend, until Hanako falls in love with Hisao in her own route, and befriends Hisao and the members of the Newspaper Club in Lilly's route.
** [[spoiler: Shizune and Misha are also this to one another unless you take Shizune's route, although Hisao says in Lilly's route that he considers both of them his friends.]]
* In ''VisualNovel/BionicHeart'', the only friend Luke seems to have at work is Tom, who is the social type trying to help Luke get out more. This makes it all the worse when [[spoiler:Luke learns that Tom was having an affair with Helen, his girlfriend]]. And then if Luke chooses to tell him about Tanya, the fugitive android hiding in Luke's apartment that was manufactured by their company, [[spoiler:[[EtTuBrute Tom sells Luke out to the company to ensure his own safety]]]].

[[folder: Webcomics]]
* In Webcomic/GiftsOfWanderingIce, chapter 1, Rikter is Elie's only friend.
* In Webcomic/TheBugPond, Eldwin is the only friend of Flash because Eldwin's the only one that can put up with him.
* Webcomic/OzyAndMillie, in the most heartwarming way. Ozy's zen nature is the only thing that can withstand Millie's craziness, and Millie gives his life much-needed excitement.
* In ''Webcomic/{{Homestuck}}'', Karkat is Eridan's only friend (and even that's stretching the definition a bit) [[spoiler:after Feferi breaks up with him]]. And even Karkat abandons him [[spoiler:after he murders Feferi and Kanaya and hopesplodes the Matriorb]].
** Kanaya is Vriska's only friend [[spoiler:after the Incident that led to the split-up of Team Scourge]], for reasons like this:
-->AG[[note]]Vriska[[/note]]: Lousy st[[VerbalTic 8]]pid godd8mn supportive fri8nd![[note]]This is right after Kanaya tries to help Vriska, who ''isn't'' being sarcastic here and is ''genuinely pissed off'' about it.[[/note]]

[[folder:Web Original]]
* In the ''Franchise/{{Noob}}'' webseries and comics, Dark Avenger's only friend is his student Précieux. Sparadrap is more than willing to be a second one, except that Dark Avenger mistakes his attempts at cross-faction friendship for a "getting your enemy's guard down" strategy.

[[folder: Western Animation ]]
* On ''WesternAnimation/{{Futurama}},'' [[FishOutOfTemporalWater Fry]] is the only one to unambiguously consider [[TokenEvilTeammate Bender]] a friend; to the others, he's TheFriendNobodyLikes at best.
-->'''Bender, first episode:''' [[LivingEmotionalCrutch Fry]], of all the friends I've had...[[CrowningMomentOfHeartwarming you're the first.]]
* ''WesternAnimation/DanVs'': [[ExtremeDoormat Chris]] is [[JerkWithAHeartOfGold Dan]]'s only friend. Chris occasionally asks why "[[TheGhost Ted]]" can't help Dan with his schemes, but whenever he does, Dan brings up some reason that the two aren't speaking to each other.
* The first season finale of ''WesternAnimation/MegasXLR'' reveals that NonActionGuy Jamie resents being taken on dangerous missions, and the main reason why he doesn't simply leave is because Coop's his only friend.
* ''WesternAnimation/{{Daria}}'': Daria and Jane (a rare combination of Alice-2 and Bob-1, respectively) are this to each other in the earlier seasons of the series. They eventually form other friendships, especially after Tom enters the mix.
* ''WesternAnimation/TeenageMutantNinjaTurtles2012'': Although Leatherhead calls the four turtles his friends, only Michelangelo (the one who actually befriended him) reciprocates this. The others are at best trusting or at worst afraid (Donatello being the latter).
* By the end of ''WesternAnimation/DannyPhantom'', [[OppositeSexClone Danielle]] still [[WalkingTheEarth on the run from Vlad]]. The only friend or family she has is Danny, the boy from whom she was cloned, who is the only member of his family aware of her existence. Of course, when it comes to Danielle, [[BigBrotherInstinct he won't hesitate to help her]].
* ''WesternAnimation/JohnnyTest'' may be Bling-Bling Boy's ArchEnemy, but both recognize that he's the only person who can ''stand'' said ArchEnemy. It helps that all of Bling-Bling's actions are driven by the desire to get a date with Johnny's sister Susan, making him more sympathetic. At one point, when Johnny was captured by the other villains, Bling-Bling went and ''rescued him'' because of this trope.
* ''WesternAnimation/{{Archer}}'': In "Heart of Archness", Archer tells Lana she is this to him. This changes over time as, by season 6, Archer is somewhat dismayed to realize that he's become best friends with Pam.
* In the ''WesternAnimation/SouthPark'' episode "You Have 0 Friends," a kid named Kip Drordy doesn't have any Facebook friends until [[TheSmartGuy Kyle]] friends him out of pity. Kip becomes [[LivingEmotionalCrutch ridiculously attached]] to following Kyle's every post; however, since Facebook is SeriousBusiness, Kyle's "friendship" with an otherwise friendless kid makes people unfriend him until he finally unfriends Kip, leaving him heartbroken. [[spoiler:He [[ThrowTheDogABone gets a happy ending]] when [[OnlySaneMan Stan]]'s thousands of unwanted Facebook friends are somehow transferred to him]].
* Before ''WesternAnimation/MiloMurphysLaw'''s first episode, [[BornUnlucky Milo]] doesn't seem to have had any close friends other than [[UnfazedEveryman Melissa]]; the series begins with him meeting his second friend, [[OnlySaneMan Zack]]. Other kids are friendly with him, but [[TheJinx prefer if he stand at least five feet away from them, thanks]].
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' [[FriendToAllLivingThings Fluttershy]] actually causes [[RealityWarper Discord]] to do a HeelFaceTurn, after becoming this to him.
* Deconstructed and ultimately averted with Adrien and Chloe in ''WesternAnimation/MiraculousLadybug''. Until the series proper, Chloe was Adrien's only friend; but it is painfully clear that it's a toxic relationship, and it doesn't help that Chloe is incredibly possessive.
