->"PAST ME IS ALWAYS SO TERRIBLE, EVEN WHEN I LITERALLY JUST FINISHED BEING HIM."
-->-- Karkat Vantas, ''Webcomic/{{Homestuck}}''

The inverse of FutureMeScaresMe, where a character sees the past and either meets or somehow witnesses the actions of their past self, and just can't stand them. Maybe they were once a villain, and now that they've reformed dislike how evil they once were, or, inversely, they're ''more'' evil and show disdain for how "weak" their past self is. Maybe they were extremely selfish as a child, and regret their indifference to the needs and feelings of others. Maybe they're just more experienced, and are annoyed with how inexperienced and impulsive they were in the past. In any case, they're constantly ticked off by their past.

See also FutureMeScaresMe, so for this from the point of view from the past self, go there. Compare OldShame, a more mundane version of this trope, and AmnesiacDissonance, where something similar happens as a result of previously-hidden memories being recovered. Contrast OtherMeAnnoysMe. See also IWasQuiteAFashionVictim and FormerTeenRebel.

Borders on TruthInTelevision, as most of us would certainly be quite embarrassed by our own past personality quirks and antics. Fortunately, we can't go back in time and meet our younger selves yet.

!!Examples:

[[foldercontrol]]

[[folder:Anime]]
* In ''Anime/{{Noein}}'', Karasu condemns his past self for being an utter coward. [[SetRightWhatOnceWentWrong Considering what he's trying to do]], not an entirely unreasonable attitude. And then [[spoiler:the titular Noein turns out to be yet another future Yuu, who hates ''both'' Yuu and Karasu.]]
* Manga/{{Naruto}}, after the TimeSkip in ''Shipuuden'', does an omake with his past self. He is shocked by the fact that he was a very annoying, obnoxious loudmouth before the TimeSkip.
* In one chapter/episode of ''Manga/UruseiYatsura'' Shutaro Mendō traveled back in time and very literally scared his younger self -- the child Mendō acted like such an obnoxious brat to his future self that he provoked the latter into attacking him with a sword. The young Mendō hid in a jar until the older Mendō returned to his own time, but that experience was what gave him his claustrophobia and fear of the dark ("WAAAN! KURAI YO SEMAI YO KOWAI YO!"). [[StableTimeLoop And what's more, the reason he traveled back in time in the first place was to prevent himself from getting that claustrophobia and fear of the dark.]]
* In a ''Manga/FairyTail'' OVA, when Natsu meets his child self via time travel, he angrily beats him up for being so weak and losing a fight to Gray. He also calls his child self stupid for not recognizing him and thinking he's a monster.
* In ''Manga/KoeNoKatachi'', when Shouya Ishida reflects on the misery caused by his younger self's bullying, he's [[TheAtoner so ashamed of what he did]] that he has an ImagineSpot of his current self stabbing his younger self, with the younger self maintaining a feckless grin the entire time.
* A non-time travel variant is a major element in ''Manga/TokyoGhoul :Re''. AmnesiacHero Haise Sasaki is haunted by visions of his past self, and states he knows that's exactly who it is. He confesses to being afraid of regaining his memories, because of who he might have been and the thought that his current self will "die". Notably, this EnemyWithin is actually a twisted version of his past self, rather than an accurate reflection of who he used to be. [[spoiler:Hinami putting herself in harm's way to save him due to her bond with his past self convinces him that the person he was must have been a good person. The next time he sees his past self, "Ken" looks like a scared and crying boy who begs Sasaki to save Hinami. Sasaki still clings to his current identity, but he no longer hates or fears Ken.]]
* Haru of ''Manga/{{Ojojojo}}'' has always been disgusted with how she used to act before she met Kawayanagi and Akane. It just takes her a while to say it out loud.
[[/folder]]

[[folder:Comedy]]
* TheFiresignTheater radio parody "Nick Danger" has the characters all transported by time machine to twenty years earlier where they meet their past selves. They all get into an angry brawl with each other, except for the aged butler Catherwoods who enjoy having someone their own age to be around.
[[/folder]]

[[folder:Comics]]
* In ComicStrip/TwistedToyfareTheatre, Future Hulk (Maestro) couldn't believe how stupid his younger counterpart is.
* During [[ComicBook/CaptainMarVell Genis-Vell's]] omnipotent madman phase, he brought Rick Jones's teenage self to the present—that is, Rick from ''before'' the Gamma Bomb accident that created the Hulk, when Rick was forced to grow up and start taking responsibility for his actions. Naturally, present-day Rick can't stand him.
* Comicbook/DoctorStrange's villains occasionally attempt mind-games like showing him his life as an [[DrJerk arrogant young surgeon]]. He's never once been tempted to go back.
* The time-travelling arc from the first volume of ''Comicbook/{{Thunderbolts}}'' took this to an extreme as the current team, consisting of some of the [[HeelFaceTurn fully redeemed]] members of the old team, ended up meeting the first set of Thunderbolts while the con was still on. The Fixer ended up talking to his past self, who was the same morals-less hothead who couldn't believe that his current self had "gone soft." [[spoiler: However, the Fixer wasn't known for his infinite patience then ''or'' now, so he ''immolates himself''. The temporal ramifications are immediately dealt with, and the Fixer has to enter a StableTimeLoop where he poses as his past self in order to keep the timeline from unwinding.]]

[[folder:FanWorks]]
* ''Fanfic/ACrownOfStars'': In the first chapter Shinji and Asuka met their six-months-older counterparts. Their older selves poked fun at them and Asuka criticised her younger self for refusing opening up to Shinji and admitting she felt lonely and afraid.
* ''Manga/ReTake'' Asuka feels somewhat vitriolic toward her past self, particularly when she enters into a romantic relationship with Shinji, whom future Asuka has much more reason to hate. There's also some self-loathing and jealousy involved.
* ''Fanfic/TheSecondTry'': Discussed. Asuka thinks her younger self would hate her since during her CharacterDevelopment she forsook all what she had lived for during her childhood and became a very different person who does not mind showing her emotions, letting other close and loves being [[spoiler:a wife and a mother.]] Shinji disagrees, stating she is being too hard on herself. Straight after he states he thinks his deeply-insecure, self-loathing, shy younger self would be shocked at seeing him... but he does not hate him since he knows why he was so full of insecurities and neurosis.
* In [[https://www.fanfiction.net/s/9763850/12/Reconciliation Reconciliation]], Asuka and Shinji [[PeggySue travel back in time]] and find their somewhat younger, pre-Third Impact selves. Promptly Shinji [[GetAHoldOfYourselfMan punches his counterpart]] [[WhatTheHellHero for never helping or consoling Asuka,]] not even after her MindRape, and Asuka slaps her younger self for never helping Shinji with his own issues.
* In ''Fanfic/KyonBigDamnHero'', Kyon thinks that Future!Kyon is arrogant and condescending and that Past!Kyon is incompetent. This is [[PlayingWithATrope played with]], as Kyon [[DiscussedTrope tells Koizumi]] that he mostly [[InvokedTrope annoys himself so that he'll remember things that he'll have to do later]], but this was played straight during a later chapter when Future!Kyon sent a text to Kyon calling him an idiot for not seeking help from Yuki during an encounter with an enemy slider.
* In ''WhiteDevilOfTheMoon,'' [[MagicalGirlLyricalNanoha Nanoha,]] who is the reincarnation of [[Anime/SailorMoon Princess Serenity,]] ''strongly'' disapproves of the Princess' actions during the era of the Moon Kingdom, (particularly running away and falling in love with Endymion despite [[LoveRuinsTheRealm the myriad risks]], and killing herself after his death) leading to a [[CallingTheOldManOut Calling The Old Woman Out]] moment against the ghost of the queen.
* In ''Fanfic/AStickySituation'', this is fairly true for Impmon. And for [[FamilyUnfriendlyViolence go]][[FamilyUnfriendlyDeath od]] reason and that's not even considering his canon actions.
* While he doesn't hate him, Future Danny from the ''FanFic/FacingTheFutureSeries'' is visibly annoyed by teenage Danny's lack of rational thought.
* In ''Fanfic/TheInfiniteLoops'', the universe sometimes resets wrong, resulting in the loopers meeting their nonlooping selves. The saner loopers are generally annoyed by their past selves's immaturity (Naruto, Ranma), {{wangst}} (Sasuke, Shinji), or some OldShame (Nabiki).
-->'''Naruto:''' ''([[DrowningMySorrows drunk]])'' Is it wrong to want to beat the shit out of your younger self?
-->'''Sasuke:''' ''(also drunk)'' Seems pretty common to me.
[[/folder]]

[[folder:Films -- Animated]]
* Another non-TimeTravel variant: In ''WesternAnimation/ToyStory2'', as Buzz Lightyear encounters a fresh-out-of-the-box Buzz Lightyear who's acting much like Buzz from [[WesternAnimation/ToyStory the first film]], Buzz moans "Tell me I wasn't this deluded…".
[[/folder]]

[[folder:Films -- Live-Action]]
* In ''Film/BackToTheFuturePartII'', Old Biff doesn't particularly like Young Biff, thinking of him as an ignorant macho idiot ([[GenerationXerox like his grandson]]), but is willing to give him the secret to infinite wealth since it will make himself rich in the future. Unfortunately, the end result is a Biff much more diabolical than either of them. Young Biff didn't care much for Old Biff either, thinking he was some crazy old coot even when Old Biff showed him his plan to make him/them rich was legit. So...I Hate Future Me?
* A non-TimeTravel example in the original ''Film/TotalRecall1990''. Quaid learns that he was originally Hauser, one of BigBad Cohaagen's agents who volunteered to have his memory erased and replaced with Quaid's personality, and doesn't particularly agree when Hauser's pre-made recordings start taunting and screwing with him. When Cohaagen tries to reprogram him as Hauser:
--> '''Cohaagen:''' You'll like being Hauser.
--> '''Quaid:''' The guy's a fucking asshole!
* ''[[Film/TheKid2000 Disney's The Kid]]'': The main character, Russ, meets himself as a child, Rusty. All he sees in his past are a bunch of bad memories.
* ''{{Film/Zathura}}'' has [[spoiler: The Astronaut, who doesn't exactly hate his past self, but since he knows his own callousness led to the loss of his brother and being stuck in the game, is fairly hard on him. However, this does eventually turn into him being very proud that the current Walter didn't make the same mistakes he did.]]
* In ''Film/{{Triangle}}'', a woman who's been caught in a series of time loops has gone completely over the edge and when she finds herself transported to the start of the day, she sees her past self yelling angrily at her son. Her response? [[spoiler: Ambush her past self and ''beat her to death.'' Somehow this does not erase her from existence.]]
* Bill and Ted think this is what's happening in ''[[Film/BillAndTed Bill & Ted's Bogus Journey]]'' when their future selves are rude to them ("I'll have to remember to be nicer to myself when I become him!"), only to discover that the "future selves" are actually {{Killer Robot}}s.
* In ''Film/DeadAgain'', an amnesiac woman regains her life but is shocked to find that she's an artist with predilection for scissors. As if that wasn't enough, [[spoiler:she was also a man in a previous life]].
* A future version of Doctor Smith uses this trope as a justification for attempting to kill his past self in the movie version of ''Series/LostInSpace''.
-->'''Future Doctor Smith:''' I never liked myself much anyway.
* In ''Film/{{Timecop}}'', Senator [=McComb=] travels from 2004 to 1994 to kill his then business partner and meets his past self in the process. He remarks that he "remembers having bigger balls", tells his past self to "lay off the fucking candy bars" and punches him in the face.
* Boris the Animal from ''Film/MenInBlack3'' despises his younger self, seeing in him the cocky idiot who cost him his arm. The younger Boris, however, seems his older self the exactly same way, as a fool who made mistakes that he himself has yet to suffer.
* In ''Film/{{Looper}}'', Old Joe has very little patience for his past self, a junkie killer who's too in love with his hedonistic lifestyle to think about the future.
* In ''Film/TheLongKissGoodnight'', Charli has little but contempt for Samantha, her amnesiac personality [[spoiler:who decided to have TheDragon's baby. She eventually realizes she cares more than she thought, and their personalities kind of merge.]]
* Tom Stahl in ''Film/AHistoryOfViolence'', an extremely mild mannered diner owner, is a non time travel example. Stahl is in fact Joey Cusack, a man too violent even for the Philadelphia Mafia. He disappeared, "killed" Joey, emerged as Tom, and years later has to reconcile the two as his circumstances force Joey to re-emerge.
[[/folder]]

[[folder:Literature]]
* In the Mistborn novel ''[[Literature/TheMistbornAdventures The Alloy of Law]]'', Miles burning gold sees two possible "pasts" of himself, and both hate each other.
** This is a common effect of burning gold, actually, since it shows you either your past or a possible past (it's rather unclear- gold is probably the least understood of the core allomantic metals, since burning it is often a disturbing experience). Vin, the heroine of ''Literature/MistbornTheOriginalTrilogy'', is also extremely uncomfortable with seeing her pre-CharacterDevelopment BrokenBird self while burning gold, and never does it again.
* Upon seeing his decisions from an observer's point of view, [[Literature/AChristmasCarol Ebenezer Scrooge]] eventually has little but large amounts of disdain for the choices his past self made, occasionally berating him despite knowing he can't hear.
* Literature/ArtemisFowl is shocked at how ruthless he used to be upon meeting his younger self in ''The Time Paradox''.
* In Jonathan Carroll's novel ''The Wooden Sea'', the narrator, Frannie, who is a cop, meets his past self, a troubled teenage bully. However, he eventually does come to see that he really was a good kid and manages to help patch things with his (teenage Frannie's) father in the past.
* In ''Discworld/NightWatch'' Sam Vimes has a more sympathetic reaction to the fact that his young self is a "twerp". As much as he's annoyed at the youth's naivety, he also displays a degree of sadness for his lost innocence and turns down the invitation to see his dearly departed mother again for fear of retreading the grief of her death.
* In Creator/StephenBaxter's novel ''The Time Ships'', when Moses meets his past self he initially doesn't like his trousers, his waistcoat, his attitude, or him. Damn young turk!
* In the "Q-Continuum" series of ''Franchise/StarTrek'' novels, Q takes Picard on a trip through his past to show him why breaching the galactic barrier would be a bad idea. Throughout the trip Q laments his past self's actions. Understandable, since he did grant [[spoiler: a sadistic EldritchAbomination and its equally monstrous cronies entrance to our galaxy which led to the destruction of an entire civilization that had actually earned Q's respect.]]
** His younger self's rash actions ([[spoiler:namely, accidentally [[ColonyDrop dropping a meteor on Earth]] and wiping out the dinosaurs]]) have also resulted in the Q Continuum forcing him to become the steward of the human race. He doesn't particularly relish the idea.
* In ''Literature/TimeEnoughForLove'' Lazarus Long goes back to when he was about four years old and visits his family in disguise. He finds his past self to be an annoying little smart-aleck and remarks that he was tempted to wring his own neck.
* In Scott Meyer's ''[[Literature/{{Magic20}} Spell or Highwater]]'', the city of {{Atlantis}} is ruled by a triumvirate of sorceresses. Two of them are actually the same person from different times. To distinguish themselves, they are called Brit the Younger and Brit the Elder (although, physically, they are identical, since all time travelers are TheAgeless). Brit the Younger is constantly annoyed by her future self's patronizing attitude and the fact that she lays claim to all the things Brit the Younger does. However, when asked, Brit the Elder admits that she treats Brit the Younger like a child because she's constantly embarrassed by her younger self's words and actions, as she's experiencing them again with [[StableTimeLoop no ability to change anything]]. In fact, both of them are looking forward to a time in several decades when Brit the Younger will go back in time to create the city of Atlantis in the first place (thus becoming Brit the Elder). In fact, most of the resentment comes from Brit the Younger, since Brit the Elder constantly keeps information secret until after it would have been useful, since this is how she remembers it.

[[folder:Live Action TV]]
* In the ''Series/RedDwarf'' episode ''Time Slides'', Lister goes back in time to visit his teenage self who turns out to be an authority-hating punk who believes everything is 'crypto-fascist'. Also, [[FutureMeScaresMe inverted]] in ''Out of Time''.
* In the ''Series/DoctorWho'' story ''The Five Doctors'', after the past Doctors return to their respective timelines, the present Doctor (the fifth one) says "I am not the man I was ... thank goodness." This implies that while he might not exactly ''hate'' his past selves, he considers them phases he's since outgrown.
** This is a recurring theme in multi-Doctor stories, which inevitably end up with the various incarnations of the Doctor bickering with each other, such as the Third and Second Doctors in "The Three Doctors" and the Sixth and Second Doctors in "The Two Doctors". In the former it's suggested that the reason the Doctor seemingly can't stand himself is that he's actually more like his past/future selves than each self would care to admit.
** The First Doctor is often a notable exception, especially in the ExpandedUniverse. Whenever a later incarnation interacts with him, they tend to see him as a voice of reason and hold him and his advice in high regard.
** This is nicely subverted in the short "Time Crash" where the Fifth and Tenth Doctors briefly meet. Five doesn't recognise his future-self at first, and is mostly annoyed that this baffling stranger has broken into his ship and is babbling on about hair and celery. Finally, he works it out, and the two of them share a touching moment. Ten reveals that Five was ''his'' favourite Doctor, and he loved being him.
*** Likewise, Five softened up and took an immediate liking towards Ten, invested in becoming his future self one day. Unfortunately, Five doesn't learn the whole truth about Ten, and goes about his merry way thinking Ten will be a happy chapter in his future, without discovering that the chapters that precede him will be very dark, such as the inevitable Time War that will eventually scar his future incarnations, and the menacing side of Ten's personality hiding beneath the surface.[[note]]David Tennant, who played the Tenth Doctor, is married to the daughter of Peter Davison, who played the Fifth.[[/note]]
** However, in "Journey's End", the Tenth Doctor pretty much states that he thinks he's "a better man" than the Ninth, and that his previous incarnation was more violent than him.
*** Conversely, Ten showed an evident dislike for the actions he took in the Last Great Time War. Whether this is regret for being forced into these actions or outright disgust that he made so many foolish decisions in the Time War was never made clear. [[spoiler: This is likely due to the Tenth not remembering the events of Day of the Doctor, where he firsthand learns that neither the War or Ninth Doctor is responsible for the destruction of Gallifrey, and still views them as abhorrent. It's shown that he forgives the War Doctor and hinted that he does the same with the Ninth by his Eleventh incarnation.]]
*** The Eleventh seemingly has no problem with the Ninth, however, as in the audio "Night of the Whisper" he leaves a lighthearted jest of an apology for the Ninth's ears. This may be due to the Eleventh [[spoiler: learning and remembering the War Doctor's role in the Time War, and being aware that neither he nor the Ninth did what was once thought, finally forgiving them, unlike his Tenth incarnation who harbored a dislike for his predecessor. ]]
*** The short "The Night of The Doctor" shows that the Eighth Doctor was actively avoiding getting involved in the war, but then decided to regenerate into "a warrior". The War Doctor is considered something of a traitor to the Doctor's legacy by subsequent regenerations, and when Eleven encountered him in "The Name of the Doctor", he expressed disgust.
** A strange version in "The Almost People". The Doctor has [[spoiler: been duplicated, making a replica exactly like the original. However, while still stabilizing, this ganger has to cope with all his memories, and starts being consumed by past regenerations. At one point he starts speaking with Ten's voice- before breaking out of it and shouting "We've moved on!"]] It doesn't necessarily mean that Eleven hates Ten, but considering the low-point of the regeneration, there might be some hard feelings.
** In "[[Recap/DoctorWhoS21E7TheTwinDilemma The Twin Dilemma]]", Six states that he hated having been Five, telling Peri that "he had a feckless charm that was never really (him)." In ''[[Recap/BigFinishDoctorWho100 The 100 Days Of The Doctor]]'', he did, however, grudgingly admit he had truly enjoyed his time as Five and compared it to "a holiday. A very wonderful holiday," and that his dislike of his fifth incarnation actually stemmed from [[TheChewToy the way the universe was treating him at the time]].
** Likewise, Seven was not too found of Five either, remarking that he was "bland, and not even one of the good ones".
** Given what Eleven has said about himself ''in general,'' not any one specific version, it may be the fact that ''every'' other Doctor's face is the face of actions the Doctor detested having had to take.
** In the AudioPlay/BigFinishDoctorWho audio drama [[Recap/BigFinishDoctorWhoSpecialsExcelisDawns Excelis Dawns]], the Fifth Doctor regards his past self as a careless freewheeler who thought he was invincible. His words strongly suggest that he was referring to the Fourth Doctor in particular. This is in response to Iris Wildthyme's remark that the Doctor isn't as fun as he used to be. The Doctor remarks that [[spoiler: Adric's death]] came as a wakeup call. In the Doctor's personal timeline, Tegan's abrupt departure [[spoiler: due to her disgust at the violence plaguing the Doctor's travels]] has yet to happen as of this story.
** In the Literature/EighthDoctorAdventures novel ''The Eight Doctors'' it is revealed that the Eighth Doctor didn't like the Seventh Doctor very much. The reasons may be due to the Seventh's reputation as TheChessmaster. Seven was prone to making cold, calculating decisions that would sometimes cross into greyer morality lines.
** In the Literature/DoctorWhoNewAdventures, Seven in turn had issues with Five and Six. In ''Timewyrm: Revelation'' Five represented the Doctor's conscience in his mental world, and Seven sealed him away out of what he thought to be necessity, until Ace freed him, reintegrating him into the Doctor's mind. In ''Head Games'', Six represented Seven's guilt over his morally dubious actions; it took until ''The Room With No Doors'' for Seven to come to terms with himself on that score.
** Subverted and played straight in ''The Day of the Doctor''. Ten and Eleven get along just fine most of the time, even moving in sync at times. However, they still can't stand [[{{Unperson}} their previous self, the War Doctor]]. [[spoiler:This changes at the end, when they not only decide to join in on doing, but also ''avert'' [[MoralEventHorizon the thing that they hated him for]]. They then part on good terms with each other]]. The War Doctor starts off unimpressed with them, thinking they are nothing more than {{Man Child}}ren, but seeing them in action and their willingness to share the burden with him leads him to deciding his future is in good hands. As for [[spoiler: the Curator, he describes the Fourth Doctor as one of his favorites, and seems amicable with Eleven]].
** Played straight in the comic ''Hunters of the Burning Stone''. Eleven stated he had nothing but contempt for One, even going so far as to glare at a psychic projection of his past self several times. When Ian tries to point out all the good things he did in his first regeneration, Eleven counters that it was he and Barbara that kept him doing the right thing.
** In the audio reconstruction of the Troughton story "Power of the Daleks" narrated by the Fourth Doctor as if he's recounting a story from his life, he seems to regard his regeneration from the First Doctor into the Second Doctor as a significant downgrade, questioning his own decision to trade [[GentlemanAndAScholar long white hair and cold dignity]] for hyperkinesis, scruffiness and flamboyance. It should be observed that [[ObliviousToHisOwnDescription the Fourth Doctor's personality is much closer to the latter type, and he also succeeded a coldly dignified, white-haired Doctor...]] He also occasionally pauses the story to cringe about just how embarrassing his own actions are.
** Averted with the Eleventh Doctor in the Fourth Doctor audio story in which he [[EarlyBirdCameo cameos]] ("Babblesphere"), where both of them seem to like each other an awful lot - and the Curator, a far future Doctor who has taken on the Fourth Doctor's personality, seems immediately fond of and affectionate towards the Eleventh in "Day of the Doctor".
** Also averted in "The Light At The End", where the Eighth Doctor is especially fond of the Fourth Doctor, with a lot of their personality quirks and tastes in common, and they get along easily. And subverted with the Eighth and the Sixth - the Eighth finds him obnoxious and embarrassing as expected, but at the same time has a great deal of respect for him, moreso than any of the others do. He certainly prefers him to the Seventh.
** On the promotional sight for the revived series, "Who Is Doctor Who?", a sighting of the Ninth Doctor states that he was in a heated argument with a "little man holding an umbrella", and obvious reference to the Seventh. In the "Eight Doctors" novel, it's stated that the Seventh isn't much liked by any of his other incarnations.
** In "Time Heist", the Twelfth Doctor uses this trope to deduce [[spoiler: both that the person who hired them to rob the bank was the future self of the bank's owner, who despises what her past self has done, and that the mysterious Architect who masterminded the heist is himself (prior to wiping his mind to prevent telepathic incursion) because nobody else could annoy him that much]].
* In an episode of ''Series/{{Charmed}}'', Paige goes back in time to when she was seventeen and is horrified to realise what a brat she was at that age.
* ''Series/SamanthaWho'' was about a woman with amnesia and as she puts her life back together is appalled to discover what an awful person she had been.
* In the American version of ''Series/{{Life On Mars|2008}}'', Sam is afraid of talking to himself as a child.
* Series/MysteryScienceTheater3000: in their episode about ''Film/TimeChasers'' Crow is immediately hostile to the Crow of 30 minutes ago because he has to explain to Crow the unforeseen consequences of their time travel.
* In an episode of ''Series/HerculesTheLegendaryJourneys'', when Hercules and Autolycus get sent into the past, Autolycus gets annoyed by his rude past self and punches him out.
** Wouldn't be the first time Creator/BruceCampbell [[Franchise/EvilDead hates someone who looks just like him]].
* Ted of ''Series/HowIMetYourMother'' damns his and Marshall's past selves for not making a decision on the apartment.
* Prince Charming of ''Series/OnceUponATime'' openly admits that he isn't a big fan of David Nolan, his curse self. He calls him "weak" and "confused" and says that David hurt the woman he loved. However, he also says that he wouldn't trade away his memories of David, because they remind him of who he wants to be.
** Captain Hook also gets a dose of this when he and Emma are whisked back through a time portal to the Enchanted Forest of old, where they encounter past-Hook in all his drunken, roguish glory. After witnessing Emma distract past-Hook by flirting with him, Hook makes his dissatisfaction known by punching his past self right in the face - a clear message that Hook has changed from the man he was by [[LoveRedeems Emma]].
* In the ''Series/StarTrekTheNextGeneration'' episode "Tapestry", Picard dies from his artificial heart failing him, and he encounters Q in what seems to be the afterlife. After much prodding by Q, Picard reveals that he regrets getting into a BarBrawl against Nausicaans ([[ContinuityNod mentioned in an earlier episode]]), suffering a near-fatal wound to his heart, which is how he wound up with his artificial heart. Picard hates his younger self for how hot-headed and arrogant he was going into the brawl. So he gets the opportunity by Q [[SetRightWhatOnceWentWrong to go back to avert the brawl]], but it makes Picard a lowly Lieutenant in a "new" future who ultimately doesn't stand out in any sense. [[TricksterMentor Q shows that if he hadn't been that arrogant young man, he'd never have become the kickass captain we know and love.]]
* In the ''Series/StarTrekVoyager'' finale "Endgame", whenAdmiral Kathryn Janeway from the future (who has admittedly become an InsaneAdmiral as per Starfleet regulations) travels back to the past it quickly becomes apparent that she simply cannot stand her younger self, and spends a fair amount of time [[TheReasonYouSuckSpeech chewing her out]].
* In ''Series/{{Fringe}}'', especially in season 5, Walter fears becoming the man he used to be [[spoiler: before William Bell removed those pieces out. Those pieces had to be reinserted in ''Letters of Transit'' as Walter's brain had become damaged due to spending years in amber.]]
* In the ''Series/SirArthurConanDoylesTheLostWorld'' episode "Absolute Power", Summerlee is shown a vision of the time he was caring for his ill wife. He left her alone, unable to stand seeing her in this state, and she died before he got back. Summerlee angrily yells at his past self and calls him a fool, but he unfortunately cannot change anything.
* In the ''Series/{{Smallville}}'' episode "Homecoming", Clark Kent gets sent to the future and meets his future self. His future self is a little annoyed by him for being naive and resistant to being a superhero, but works with him since not even Superman can stop two disasters at once.

[[folder:Music]]
* The Music/GarfunkelAndOates song "29/31". It follows a woman at the ages of 29 and 31; her 29-year-old self is an [[TheIdealist idealistic]] NaiveEverygirl while her 31-year-old self is a [[TheCynic cynical]] DeadpanSnarker, having realized her life didn't go as well as she expected it to. Her older self (played by Music/{{Riki|Lindhome}}) is annoyed by her younger self (played by Kate), while her younger self is horrified by what she has become.
* Plenty of country music songs about regretting one's wilder days abound. Prominent examples include "Choices" by Music/GeorgeJones and "Yesterday When I Was Young" by Roy Clark. The point is that, now older and wiser, the singer is filled with regret for their past mistakes and they wished they had never done what they did.
* [[Music/RelientK Relient K's]] song [[https://www.youtube.com/watch?v=VQJt2yFtS84 "Who I Am Hates Who I've Been."]]
--> ''"I'm sorry for the person I became\\
I'm sorry that it took so long for me to change\\
I'm ready to be sure I never become that way again\\
'Cause who I am hates who I've been\\
Who I am hates who I've been."''

[[folder:Professional Wrestling]]
* Wrestling/JohnMorrison's attitude on ''The Dirt Sheet'' after he traveled back in time to meet Johnny Nitro.[[/folder]]

[[folder:Video Games]]
* In ''[[VideoGame/{{Spellforce}} Spellforce: The Order Of Dawn]]'', [[spoiler:the BigBad is the past version of the BigGood.]] Naturally this relationship applies. At the end of the game, [[spoiler:the BigBad undergoes a HeelFaceTurn and goes back in time to stop his past self from causing TheEndOfTheWorldAsWeKnowIt. This leads to a StableTimeLoop, wherein he becomes the BigGood.]]
* The ''Videogame/WorldOfWarcraft'' quest, "Mystery of the Infinite," has you fighting along your future self to defend an object from the Infinite Dragonflight. Throughout the fight, your future self mocks you with tidbits such as:
-->'''Future You:''' Look at you fight; no wonder I turned to drinking.
** And then when you do the sequel quest "Mystery of the Infinite, Redeux", you're mocked just as much by Past You:
--->'''Past You:''' I just want you to know that if we get through this alive, I'm making sure we turn out better than you. No offense.
* [[VideoGame/BlazBlue Hakumen]] has [[ThatManIsDead renounced his old identity]] as [[spoiler:Jin Kisaragi]]. He considers killing his "past incarnation" to be atonement for his/[[spoiler:Jin]]'s sins.
* In ''VisualNovel/FateStayNight'' this is how [[spoiler:Archer feels about Shirou. He hates Shirou for being so weak, naive, and idealistic. He's willing to kill Shirou, even though this would presumably erase him from existence, because his past choices and mistakes made his life completely miserable. Archer eventually dies peacefully trusting that Shirou will not become like him.]]
* In ''[[VideoGame/CityOfHeroes City of Villains]]'', one villain "morality mission" has you meet three future versions of yourself, two of which think you're an idiotic weakling. [[spoiler:The third is TheAtoner, whose pleas for you to do the right thing you ignore.]]
* The normally [[TheStoic stoic]] Auron in ''VideoGame/FinalFantasyX'' actually ''attacks'' his past self when confronted with a phantom echo of his past in the ruins of Zanarkand. Since it's only an echo, he ends up fruitlessly shouting and swinging his sword to no effect.
* ''Videogame/SaintsRowIV'' sees present-day Shaundi come face-to-face with the Shaundi from ''SaintsRow2''. The two don't get along: present-day Shaundi thinks past-Shaundi is a useless drug-addled promiscuous load, while [[FutureMeScaresMe past-Shaundi thinks present-day Shaundi is a joyless, angry killjoy who really needs to light a bowl]].
--> '''Present-day Shaundi:''' My problem? My problem is that I used to be you.
* The ''VideoGame/SamAndMaxFreelancePolice'' episode "Chariots of the Dogs" has several differently aged versions of Sam and Max, including a young, nerdy Sam who loves computers and disgusts his older self.
--> '''Young Sam''': Wow, I've never seen anything that advanced. It must have at least 640 kilobytes of RAM!
--> '''Sam''': Ew. Whatever, kid.
** Sam also pulls a gun on his younger self after he calls him fat.
* In ''[[VideoGame/LegacyOfKain Soul Reaver 2]]'', Raziel's past [[AmnesiacDissonance self]], a {{Jerkass}} KnightTemplar, scares him.
* In ''VideoGame/JakIIRenegade'', Young Samos and Old Samos do ''not'' get along, to the point where ''[[JerkWithAHeartOfGold Daxter]]'' has to mediate.
** [[spoiler: Averted with Young Jak as he's one of the few people that angry Older Jak gets along with.]]
* ''Videogame/BioshockInfinite'' has [[spoiler: Father Comstock, the BigBad of the game, who is also a version of the protagonist, Booker [=DeWitt=] from an alternate universe who underwent a baptism following the Massacre at Wounded Knee, got a new name, and found religion. Comstock has nothing but scorn for the Booker we play as, from a universe where he ''refused'' the baptism, believing him to be a godless, self-destructive "False Shepard".]]
* Fate's final battle in ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Battle of Aces'' has Fate confronting a copy of herself based on her memories of her DarkAndTroubledPast. The match revolves around her trying to convince her angst-filled past copy that, eventually, everything will become all right.
* In ''VideoGame/MarioAndLuigiPartnersInTime'', Bowser ends up fighting with his past self over a volcano that both of them think would make a great evil lair. They eventually decide to [[MyFutureSelfAndMe team up]], but neither one ever figures out the other's identity.

[[folder:Webcomics]]
* Subverted in ''Webcomic/TheLastDaysOfFoxhound'', where The Sorrow shows the amnesiac Liquid his past in order to to show him how, violent, cruel and indifferent to humanity he was. Cue Liquid gushing over how much of a BadAss he was.
* A book 4 arc of ''Webcomic/{{Fans}}'' pits the science fiction club against their book 1 versions, and nearly all of them have this reaction.
* Karkat of ''Webcomic/{{Homestuck}}'' gets into arguments with his past selves so often that it's practically become a RunningGag. And his future selves hate him just as much. He provides the page quote. It should probably be noted that [[BizarreAlienBiology the troll reproductive cycle]] has two reproductive relationships: one analogous to human romance (flushed, obviously represented by a heart) and one [[FoeYay based entirely on mutual hatred]] (caliginous, represented by a spade). [[ScrewYourself Karkat <3< Karkat]] is all ''but'' confirmed by canon.
** The situation described in the page quote ''literally happens'' when he posts a cross-time memo and is immediately responded to by himself 10 minutes in the future. They proceed to spend that entire time arguing, so that mere moments after the argument ends, he sees his past self posting the memo and responds as the other side of the argument.
** Jade gets sick of [[spoiler: Jadesprite]]'s sobbing pretty quickly. When she refuses to do the one thing that could probably accomplish her goal [[spoiler: of going back to being dead]], present Jade loses it and starts [[GetAHoldOfYourselfMan smacking sense into her, literally]]. It gets stranger: Since [[spoiler:Dream Jade]] went back in time 13 years [[spoiler:after dying]], [[spoiler:Jadesprite]] is technically older than Jade, but her personality is noticeably more flawed.
** Vriska is soured on her former AttentionWhore GloryHound behavior when she witnesses Aranea, the alternate universe version of Vriska's ancestor, cause a lot of trouble with her Attention Whore Glory Hound antics.
*** Vriska's brushes with this trope get even worse later when [[spoiler: she meets the Retcon version of herself who never died and went through the CharacterDevelopment she experienced, and is thus still a borderline sociopathic jerk. Said version proceeds to insult and bully Vriska for not being a jerk anymore (she claims that Vriska has become a loser), and is so incredibly vicious and cruel that Vriska actually ''cries''.]]
** Aradia is a little disturbed by how eager the ghosts of her alternate timeline selves are for violence...and by how many of them are being courted by Equius all at once.
* A non-TimeTravel example occurs in ''Webcomic/TheDragonDoctors'' when Kili and Greg go to part of the SpiritWorld where a person's past self resides. Kili, a kind, sensitive shaman, is confronted by her bratty teenage self and Greg, a mellow writer, is distraught when he sees his TotallyRadical headbanger self.
* ''[[{{Walkyverse}} Shortpacked!]]'': [[http://www.shortpacked.com/2010/comic/book-12/02-batman-jokes/thepoorfool/ Modern Age Batman meets Golden Age Batman.]] And yes, Golden Age Batman ''[[CharacterizationMarchesOn really was]]'' [[http://lydeanwooster.com/comics/batman/DC029.shtml that much]] of a [[SuperDickery dick]].
* In ''Webcomic/ManlyGuysDoingManlyThings'', the Commander fulfills a StableTimeLoop by going back about a minute to beat up his past self and steal his coffee. As he leaves, he tells his past self not to be such a "candy-ass" so that this won't happen again.
* From ''Webcomic/{{Narbonic}}'': "I'm your future, and I hate you. I'm [[spoiler: going to electrocute you now.]]"
* ''Webcomic/TemplarArizona'': In the bonus comic [[http://templaraz.com/bonus_comics/confirmation.php Confirmation]] the loud, boisterous adult Reagan, meets and torments her insecure, reserved, [[spoiler: and racist[[note]] moulignan is the Italian equivalent of nigger in case if you're wondering[[/note]]]] younger self.
* In ''Webcomic/TheGreatestGift'', Hazel Lulamoon is actively ''afraid'' of the mare she used to be before her HeelFaceTurn, having a nightmare about Past!Hazel and calling her a monster.
* In ''Webcomic/{{Sinfest}}'', Fuchsia is terrified after she has a flashback to her pre-HeelFaceTurn days.
* In one arc of ''Webcomic/FullFrontalNerdity'', Frank has Nelson, Lewis and Shawn retire their successful player characters and make up new ones. Their new characters meet their old characters as non-player characters. Frank insists on role-playing them all in character as ruthlessly ambitious {{Munchkin}}s, much to Nelson, Lewis and Shawn's dismay.
* Future Stein appears to feel this way about his younger counterpart in ''Webcomic/{{Frankie and Stein}}''.
* The main character of ''Webcomic/TwoKinds'', [[AmnesiacHero Trace]] is suffering from amnesia since the start of the comic, which is good since he was kind of [[KnightTemplar a jerk]]. It leads to this conversation:
-->'''Eric''': "Templar laws have, in recent years, made it a crime for slave traders such as myself to free our slaves voluntarily."
-->'''Trace''': "What? Why? What kind of evil person would make a law like th...it was me, wasn't it?"
-->'''Eric''': "…Yes"
* In ''WebComic/SonicTheComicOnline'' this is Sonic's reaction to meeting his [[JerkAss past self]] It leads to this conversation:
-->'''Past Johnny''': "Look - there's a PLAQUE on the statue (a statue of Johnny Lightfoot build after his death)."
-->'''Past Sonic''': "Heh, probably says 'JOHNNY LIGHTFOOT - PROFESSIONAL SIDEKICK'."
-->'''Present Sonic''': "YOU CREEP! Johnny was more of a hero than you'll EVER be!
* ''Webcomic/MagicalTwelfthGraders'': [[spoiler:The Yeorum from the future is well aware that pretty much everything bad that ever happened to Gyeowul, and most of the bad stuff happening now, is Yeorum's fault. She finds her disgusting]].
* Taken to extremes (like so many things) in ''SaturdayMorningBreakfastCereal'', in which two future versions of a guy decide to go back and [[http://www.gocomics.com/comic/explore/1338661/17 kill his teen self]].

[[folder:Web Originals]]
* This is one of the older Joes' reaction in the ''Website/CollegeHumor'' video "Film/{{Looper}} Has Sex with Himself" when the younger Joe refuses to [[ScrewYourself give the older ones a blowjob]].
* ''WebVideo/CrashCourse'': John Green's general reaction to John-Green-from-the-Past, who plays the role of student.
-->'''Present!John''': Can we just pause for a moment to consider the astonishing fact that most T-shirts see more of the world than most of us do?\\
'''Past!John''': Mr. Green! Mr. Green! But T-shirts can't see the world because they don't have eyes.\\
'''Present!John''': Look, Me-from-the-Past, it's difficult for me to isolate what I hate most about you, because there is so much to hate, but very near the top is your habit of ignoring everything that is interesting or beautiful about our species in favour of pedantic snivelling in which no-one loses or gains anything of value.

[[folder:Western Animation]]
* ''WesternAnimation/{{Arthur}}'': In a dream that Prunella has about her giving a gift to Francine, she ends up scolding herself, only to realize that it is her.
* In the ''WesternAnimation/{{Gargoyles}}'' Avalon arc, the Archmage becomes quite irritated with his younger self for being impulsive and not thinking things through. He takes it upon himself to tutor the younger him, and frequently makes jabs about how incompetent he is.
** Ironically, the past self is only a few days younger then the future self. Granted, a ''lot'' happened in those few days, including several magical transformations which increased his intelligence and dramatically boosted his power.
* In an episode of ''WesternAnimation/JusticeLeague Unlimited'', [[WesternAnimation/BatmanBeyond old Bruce Wayne]] meets his past self and, during a suspect's interrogation, comments that "I can't believe I was ever that green." Afterwards, Old Bruce teaches his past self how to properly interrogate a criminal, foregoing the traditional method of terrifying the {{Mook|s}} and instead simply ''beating'' information out of him. This leads to an amusing GoodCopBadCop with Batman playing both roles, and past Batman's teammates expressing their disbelief at the Batman they know being able to pull off Good Cop.
* After the {{time skip}} in ''WesternAnimation/ReBoot'', Matrix expresses constant dislike of the memories of himself as a kid. During a dream in one episode, he even comes face to face with his younger self and they argue. Eventually a copy of his younger self joins the cast and Matrix treats him like a younger (annoying) brother. The relationship is eventually inverted. His younger self dislikes Matrix's bitterness while Matrix tries to regain some of the idealism of his youth.
* ''WesternAnimation/SouthPark''- In the "Go God Go" duology, Cartman tries [[ItMakesSenseInContext warning himself not to freeze himself by using a phone designed to make prank calls in different periods in time]]. However, Past!Cartman doesn't believe Future!Cartman, and just insults him. This leads to Future!Cartman calling his past self an asshole. Then at the end of the episode, when Cartman is clearly going to do the whole mess again, he gets a call from his future self and acts exactly the same way.
* ''WesternAnimation/Ben10UltimateAlien'': Following a trans-dimensional mishap in one episode, 10-year-old Ben Tennyson meets his 16-year-old self. Ben doesn't hate his younger self, but he does find him incredibly rude and annoying, scolding him when he makes rude comments.
* In ''WesternAnimation/GeneratorRex'', the eponymous character, suffering from chronic LaserGuidedAmnesia, finds out that he once sold out his best friends to a crime boss. Also, though he never mentions ''hating'' it, per se, Six was a cold-hearted {{Jerkass}} and wannabe [[TheCasanova Casanova]] before he met Rex, and temporarily reverts to this when he loses six years of memory.
* A RunningGag in ''WesternAnimation/{{Futurama}}'' has characters always acting hostile towards past, future ''and'' alternate versions of themselves. Except Bender. Because if there's one thing Bender loves, it's Bender.
* Comicbook/VandalSavage in the ''WesternAnimation/JusticeLeague'' episode "Hereafter". It took 30,000 years of self-imposed exile on the ruined Earth (which he ruined) as the last human being alive for him to give up his megalomania. As Savage prepares to send {{Franchise/Superman}} back in time, Savage tells Superman that he must stop Savage's past self no matter what.
* While it's never directly stated, it's hard to believe future Twilight isn't thinking this in the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "It's About Time". All she wants is to warn her past self about something, but her past self just won't shut up.
* In ''WesternAnimation/AmericanDad'' episode "May the Best Stan Win", a cyborg Stan comes back in time to steal Francine from his past self, having realized in the intervening 1000 years how much he missed her. He actually convinces Francine to leave Present Stan by telling her "That man's just going to keep letting you down; I know, I ''was'' him!" When Present Stan fights back, Cyborg Stan has absolutely no problem beating him senseless.
* Grouchy Smurf in ''WesternAnimation/TheSmurfsAChristmasCarol'': "Past me is so annoying."
* Goes both ways in one ''WesternAnimation/DrawnTogether'' episode where Captain Hero finds a way to communicate with his teenage self and decides that he is an absolute loser who deserves to be punished. He repeatedly tricks his past counterpart into performing depraved acts in public, until his younger self, realising what a {{jerkass}} future Hero is, retaliates and arranges for him to be arrested. [[PlayingWithATrope Played with]] in that both versions of Hero are too dumb to quite understand the implications of them being the same character in different time periods (future hero remembers suffering similar abuse but opts for revenge by continuing the cycle instead of realising that he can break it).
* In the Daffy Duck short ''WesternAnimation/DuckAmuck'', the animator deliberately misaligns the tracking of the film so two frames of the film are temporarily visible. Daffy then proceeds to get into a argument and fist-fight with the version of himself from one frame (1/24th second) ago.
-->'''Daffy 1:''' Listen bub, if you wasn't me, I'd smack you right in the puss!\\
'''Daffy 2:''' Don't let ''that'' bother you, jack!
* Dark Danny from ''WesternAnimation/DannyPhantom'', being the psychotic evil ghost that he is, can't stand his heroic younger self or any part of his past life. He does admit at one point that he misses Tucker's sense of humor, though.
* In the ''WesternAnimation/StevenUniverse'' episode "Steven and the Stevens", Steven uses a magic time-travelling hourglass to team up with three temporal duplicates of himself and start a band. Unfortunately the other Stevens start getting on the original Steven's nerves, and he starts to realize how annoying he can be.

[[folder:Real Life]]
* People who have been heavily bullied often turn out to experience this, even hating things they did ''when they were a baby'', just because it draws them back to the belief that what they are doing, or have done, is inherently wrong.
* One commentator on Website/KnowYourMeme's article on [[http://knowyourmeme.com/memes/katy-t3h-pengu1n-of-d00m Katy t3h PeNgU1N oF d00m]].
-->'''[[RedHeadedHero Crimson Locks]]''': Oh, hello, past self. How unpleasant it is to see you again.
* "Fortunately, we can't go back in time and meet our younger selves yet. ...." except for those of us who kept diaries. This trope is the leading cause of {{Diary}} burnings. Don't do it. Years from now you'll wish you'd hung onto it, no matter what it says.
