The inverse of Future Me Scares Me, 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 Future Me Scares Me, so for this from the point of view from the past self, go there. Compare Old Shame, a more mundane version of this trope, and Amnesiac Dissonance, where something similar happens as a result of previously-hidden memories being recovered. Contrast Other Me Annoys Me. See also I Was Quite a Fashion Victim and Former Teen Rebel.
Borders on Truth in Television, 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.

- Kaguya from Kaguya-sama: Love is War is deeply ashamed by her past as an Ice Queen, referring to herself as having been "a terrible woman with a twisted, disfigured heart."

- Mirai of the Future has an amusing moment where Future-Kun tries to tell Kun that not wearing his favorite pants isn't the end of the world and he should instead appreciate being able to make happy memories with his family.

- Nino was initially the most hostile towards Fuutarou for no other reason than "he's an intruder in our home", outright trying to sabotage his efforts to get them to study, with no consideration whatsoever for his situation (he needs the money from his work as a tutor to help support his family).

- A non-time travel variant is a major element in Tokyo Ghoul :Re. Amnesiac Hero 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 Enemy Within is actually a twisted version of his past self, rather than an accurate reflection of who he used to be. 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.

- In one chapter/episode of Urusei Yatsura 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!"). 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.
- The Firesign Theatre radio parody "Nick Danger" has the characters all transported by time machine to twenty years earlier where they meet their past selves.

- Atomic Robo: During each of Robo's fights with The Shadow From Beyond Time, he gets pulled into a pocket dimension within The Shadow where everything exists simultaneously outside of linear time. Because he fights this thing four times over a span of about 80 years, this results in four different versions of Robo being in the same place at the same time. While the 1957, 1971, and 2009 Robos all get along well, having each done this at least once before and knowing exactly what to do, they are mutually derisive of the 1926 Robo, who is the youngest and least experienced of them.
- During Genis-Vell's omnipotent madman phase, he brought Rick Jones' teenage self to the presentthat 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.

- Kang The Conqueror is a mix of this trope and Future Me Scares Me, with the Continuity Snarl that is his publication history resulting in him being locked into an eternal war with past and future versions of himself.

Though Old Logan also tells his younger self to never lose his Determinator attitude like he did.
- In Savage Dragon, Savage Dragon himself hates and fears his past self Emperor Kurr. Not really surprising since Emperor Kurr is a genocidal warmonger who pretty much wipes out humanity and killed the kids he sired as Dragon with no remorse.
- A common theme in Spider-Man is how Peter is truly ashamed of his younger teenage self for his selfishness and especially the Bystander Syndrome which taught him responsibility. This is frequently seen Straczynsks run where Spidey flashbacks to his school days and the mistakes he made and the narration boxes detail how much Peter laments his attempts to go with the popular crowd instead of trying to help his friend Charlie Weiderman. Averted when present Spider-Man meets his old wheelchair-bound self in a Deadpool/Spider-Man crossover as they got on very well.

- The time-travelling arc from the first volume of Thunderbolts took this to an extreme as the current team, consisting of some of the 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."

- Calvin and Hobbes: When Calvin travels to the (very near) future to get his completed homework from his future self, three different versions of him end up fighting over which of them should have done the homework. Averted with Hobbes in the same story, as his egotism is of a sort that gets along with itself. "You're right, as always, Hobbes."
- This trope, combined with Future Me Scares Me, is present in Spirit Soldier's "Let's Watch Our Show" Plot of Danganronpa: Trigger Happy Havoc, Class 78th Watches the Future, as the ones watching to the visual novel are, as in the title, Class 78. Since Makoto and Kyoko are able to figure that the class had lost their memories, they, minus Mukuro since she's playing as Junko experience how they behaved in the beginning. With them able to see their behavior from the more neutral view of Makoto, some experience frustration with the way they behave, such as Kyoko with her inability to trust or let go of grudges, Toko for her paranoia and distrust, Kiyotaka for his insensitivity towards Sayaka being murdered in Makoto's room and boisterous attitude to studying, and Byakuya with his arrogance and belief he will never lose.

- I Think We'll Be Okay: Kosuke at the beginning of the story is horribly lazy and while she's not totally inconsiderate of her friends and family's feelings, she'd much rather carry on her poor habits than make an effort to change. Then her parents are unexpectedly killed in a car accident, leaving her to take care of her younger siblings. The experience makes her a much more mature Determinator, but she's swamped with guilt for her past actions and how she treated her loved ones.
- In The Infinite Loops, the universe sometimes resets wrong, resulting in the loopers meeting their nonlooping selves (an event referred to as a Mini-Me Loop). Since Loopers have had a lot of character development from their baseline selves, they tend to be annoyed by their non-looping counterparts displaying character flaws they grew out of literal eons ago (the non-loopers in turn tend to be scared of their looping selves). Sasuke, for example, has made up with Naruto and can't stand his teenage self's Wangst and refusal to better himself, while Naruto has matured a good deal and thinks his teenage self is a complete brat.
Naruto: [drunk] Is it wrong to want to beat the shit out of your younger self?
Sasuke: [also drunk] Seems pretty common to me.
- In Jonathan Joestar, The First Jojo, Older Joseph clearly holds distaste for his younger self.
- In Kyon: Big Damn Hero, Kyon thinks that Future!Kyon is arrogant and condescending and that Past!Kyon is incompetent. This is played with, as Kyon tells Koizumi that he mostly 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.
- Harry Potter in Metagaming? casually refers to his past self as a "well-meaning idiot" over how he first tried to create a society ruled by intelligent and rational people only then later fostered as much hatred between various groups as he could when his first plan failed miserably.

While Phoebe doesnt hate her past self, she is embarrassed at her younger selfs flirtatious nature, with the younger Phoebe initially assuming that Chris was her future boyfriend before the older Piper identifies him as her own son.
- One step backwards and Three forwards: Felix utterly despises how he used to be as Adrien, back in the original reality. Hindsight makes it all too easy to berate himself for his past decisions, as he rarely took his responsibilities as a superhero seriously and rarely stood up against his father, Chloe or Lila. In particular, he blames himself for not warning Ladybug about how he'd discovered Luka's corpse; had he done so, they might have been able to prevent Hawkmoth's triumph. It also doesn't help that he was split into two when reality was rewritten, with Felix getting all of the original Adrien's memories while his other half remains as one of Lila's prizes.
- Non-Time Travel example in Pokémon Reset Bloodlines with Misty's Gyarados. He's rather upset when Misty buys a Magikarp aboard the S.S. Anne (partly due to her goal of catching every single Water-type Pokémon), because it reminds him of the time he was a puny fish, and he doesn't like it.
- Pony POV Series: Shining Armor has a dream where he relives the day he met Princess Cadance. Shining yells at his past self because he only thought about how hot Cadance was and how he wanted to make her his bride.

- In Reconciliation, Asuka and Shinji travel back in time and find their somewhat younger, pre-Third Impact selves. Promptly Shinji punches his counterpart for never helping or consoling Asuka, not even after her Mind Rape, and Asuka slaps her younger self for never helping Shinji with his own issues.
- Reunion is a Wandering Son story where a now-adult Saori realizes what a terrible, ignorant kid she was. She hates her transphobic and two-faced behavior from a few years prior.
- RWBY: Epic of Remnant: Just like the regular EMIYA, EMIYA Alter hates his past self Shirou Emiya. He's horrified when he becomes a teenager again. While his skin is still black, his eyes are still yellow, and his hair is still white, his face and body look like Shirou's again.
- The Second Try: Discussed. Asuka thinks her younger self would hate her since during her Character Development 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 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 A Sticky Situation, this is fairly true for Impmon. And for good reason and that's not even considering his canon actions.
- In Twisted Hilaritys Uke, there is a point where Sesshomaru finds the well and goes through it to meet his future self, and his future self is... shall we say, less than pleased with how he remembers himself behaving toward his new mate, Inuyasha. Future Sesshomaru decides to teach himself a lesson. It is arguably the best damned scene in the story thus far.
- In White Devil of the Moon, Nanoha, who is the reincarnation of 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 the myriad risks, and killing herself after his death), leading to a Calling The Old Woman Out moment against the ghost of the queen.
- In Chapter 50 of BlazBlue Alternative: Remnant, Makoto admits to Blake that in the past, she was incredibly bitter and violent towards humans for all the suffering they put her and other Faunus through, and there was a time when she actually considered in taking part in the White Fang's crusade against humanity. She tends to look back on her past self with a lot of self-loathing and hates wondering what she could have become had she never met Tsubaki and Noel.
- Another non-time travel variant happens in the first Cars movie. When Lightning Mcqueen first arrives at Radiator Springs, Doc Hudson utterly despises him at first because the younger runner's cocky, boastful attitude brings Doc lots of awful reminders of his time as a racer himself. Even after Lightning gets some Character Development and learns to be a better car, Doc still can't stand him and gets rid of him by telling the media and the authorities Mcqueen's location so they can take him back. Realizing he made a mistake, Doc and his friends show up at the decisive Piston Coup race to help Lightning.
- DC Showcase Batman: Death in the Family sees one of the Red Robin paths with Jason (after Tim makes Jason have a Heel Realization and Jason decides to spare Two-Face) reflect on his earlier comment about "Evil can't be cured; only killed," and states "Whoever said that is a jackass."
- An odd example in The Emperor's New Groove—there's an Interactive Narrator version of Kuzco who represents his attitude at the beginning of the story, claiming that his misfortune is everybody else's fault. By the midpoint of the story, however, the "real" Kuzco has undergone enough Character Development to tell him off.
- Downplayed in Frozen II, Elsa winces upon seeing an apparition of her past self singing "Let It Go."
- Mixing with Future Me Scares Me in The LEGO Movie 2: The Second Part, Rex Dangervest is revealed to be an embittered Emmet from the future, seeking to ruin his past self's life to turn him into Rex. When Emmet reacts in horror to his plan, Rex can only huff "I am so disappointed in myself" before strapping Emmet to a slingshot and forcibly throwing him under the dryer to set him on the path to becoming Rex.
- My Little Pony: Equestria Girls: When Sunset Shimmer refers to her past self (and in particular, the "raging she-demon"), it is always with disgust. Her Image Song, "My Past Is Not Today" is about how she's not that person anymore and shows her taking her three "Fall Formal Princess" pictures off the school's wall and throwing them in the trash.
- A non-Time Travel variant: In Toy Story 2, as Buzz Lightyear encounters a fresh-out-of-the-box Buzz Lightyear who's acting much like Buzz from the first film, Buzz moans, "Tell me I wasn't this deluded..."
- In Back to the Future Part II, Old Biff doesn't particularly like Young Biff, thinking of him as an ignorant macho idiot (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-Time Travel example in the original Total Recall (1990). Quaid learns that he was originally Hauser, one of Big Bad 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!
- Star Wars
Darth Vader:(in Star Wars Rebels to Ahsoka Tano) Anakin Skywalker was weak. I destroyed him.
- Darth Vader for the most part loathes his past self as Anakin Skywalker. Somewhat due to the regret and sadness over how his life turned out, but mainly due to him perceiving Anakin as a pathetic weakling who lacked the immoral Sith beliefs. When his son Luke and others from his past refer to him as Anakin, Vader dismisses it since "Annie" is dead as far he's concerned. There's also a good chunk of the fanbase who actually agree with Vader's sentiment, even though his last moment in Return of the Jedi was him choosing to die as Anakin.
- On the flipside Anakin's glimpses into the future as seen in Star Wars: Clone Wars, Star Wars The Clone Wars 2008 and Star Wars Battlefront II (2017) where he can meet Vader in person have terrified Anakin and casued him go through Heroic BSoD at seeing what he'll become.
- Luke in The Last Jedi has real troubles in regards to his younger self and is annoyed at Rey treating him like the legend he is and even throws his (and his father)'s lightsaber away when Rey hands it to him. This is likely due to Luke's shame at the new Jedi Order he created being destroyed by his nephew Ben and him failing to stop it and save Ben from succumbing to The Dark Side as well as contemplating killing Ben to prevent it all happening. On other hand Luke sneaks into Millennium Falcon while Rey and Chewy are sleeping implying he does miss the old days and hates how things turn out when R2-D2 puts on Leias holographic message from A New Hope, he complains "That's unfair". Luke redeems himself in the climax saving what's left of the Rebellion by tapping into the Force once again.
- 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.
- Zathura has 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.

- In 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.

- In Lost in Space Future Smith manhandles his past self, utterly disgusted with his petty ambitions, and tosses him away, apparently killing him. His past self is terrified of him since he's mutated into a giant alien spider monster courtesy of a bite he received earlier in the film.
Future Smith: I never liked me much anyway.
- X-Men Film Series:
- Right before Wolverine goes back in time in X-Men: Days of Future Past, Magneto expresses doubts about the mission success—not because of a lack of faith in Wolverine, but how his and Professor X's younger selves were. Given the actions his younger self takes to prevent the Bad Future, he was right to worry.

- In the Mistborn novel 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 Mistborn: The Original Trilogy, is also extremely uncomfortable with seeing her pre-Character Development Broken Bird self while burning gold, and never does it again.

- Downplayed in Night Watch Discworld. Sam Vimes has a more sympathetic reaction to the fact that his young self is a "twerp".

- In Stephen Baxter'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 Star Trek 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 a sadistic Eldritch Abomination 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.
- In Time Enough for Love 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 Spell or Highwater, the city of Atlantis is ruled by a triumvirate of sorceresses. Two of them are actually the same person at 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 The Ageless). 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 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.
- In the third Takeshi Kovacs novel the antagonists sleeve a copy of Kovacs from when he was still in the Envoy corps to hunt him down. The Kovacs with roughly a subjective century more experience finds him an annoying punk.
- The antagonism between the two Rimmers in Red Dwarf: Infinity Welcomes Careful Drivers is presented like this. (There's hints of it in the episode, but the book states it explicitly.) The duplicate Rimmer is essentially his past self from before the accident, whereas the original Rimmer has mellowed slightly through his post-resurrection experiences.
- In the Imperial Radch trilogy, Tisarwat gets this twice over after experiencing Death of Personality from being temporarily assimilated into Anaander Mianaai's mental gestalt. She remembers being both a fatuous teenager and an ancient, callous dictator and feels each residual personality's disdain for the other's past.
- The Old Kingdom novel Goldenhand Inverts this: Chlorr's Soul Jar is the part of her spirit that didn't fall to Free Magic corruption when she was the young, living woman Clariel. When Clariel is awoken from slumber and gains access to Chlorr's Ghost Memories, she starts weeping in horror at the monster she went on to become. She also helps defeat Chlorr for good.
- In an episode of Charmed, Paige goes back in time to when she was seventeen and is horrified to realize what a brat she was at that age.
- Doctor Who:
- 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 Expanded Universe. 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. He also has enough of a commanding presence to convince all of his later incarnations to put aside any differences they might have and focus on working together on the task at hand. An exception to this exception occurs in "Twice Upon a Time", with the Twelfth Doctor being mortified by his sexist former self, and the novelization making it clear that the First Doctor returns that dislike and is intentionally playing it up to get a rise out of him.
- In "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.
- In "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 "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 the way the universe was treating him at the time.
- Likewise, Seven was not too fond of Five either, remarking that he was "bland, and not even one of the good ones".
- This is subverted in the short "Time Crash", where the Fifth and Tenth Doctors briefly meet. Five doesn't recognize 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 favorite Doctor, and he loved being him.note Likewise, Five softens up and takes 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.
- 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 shows 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. This is likely due to Ten, by virtue of a Temporal Paradox, not remembering the events of "The Day of the Doctor", where he firsthand learns that neither the War nor 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. Nine and Ten are shown to get along just fine, however, in the comic event "The Lost Dimension" when the two team up with the Twelfth Doctor. Nine even puts his arm around Ten's shoulders when offering to take his displaced incarnations and their companions back to their TARDISes.
- 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 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 harboured 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 downplayed version comes with the War Doctor himself. In "Lighting the Flame", which takes place shortly after his regeneration, he expresses a geniune sense of nostalgia for his time as Eight, musing on how full of hope he was back then, but he also thinks that it was incredibly naive and foolish of Eight to think that he could just stay out of the Time War forever.
- A strange version in "The Almost People". The Doctor has 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.
- 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 Big Finish Doctor Who audio drama "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 Adric's death came as a wake-up call. In the Doctor's personal timeline, Tegan's abrupt departure due to her disgust at the violence plaguing the Doctor's travels has yet to happen as of this story.
- In the 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 The Chessmaster. Seven was prone to making cold, calculating decisions that would sometimes cross into greyer morality lines.
- In the Doctor Who New Adventures, 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 their previous self, the War Doctor. This changes at the end, when they not only decide to join in on doing but also avert 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 Children, and as soon as he figures out who they are (having assumed that they're future companions) demands to know if he's going through a midlife crisis. After seeing them in action, however, his opinion does a complete 180 and he considers them better than him, even to be great, remarking, "Great men are forged in fire. It is the privilege of lesser men to light the flame," with himself being the lesser man. That and their willingness to share the burden with him leads him to decide his future is in good hands. As for the Curator, he describes the Fourth Doctor as one of his favorites, and seems amicable with Eleven.
- Played straight in the Doctor Who Magazine comic Hunters of the Burning Stone. Eleven states he has 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 "The 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 long white hair and cold dignity for hyperkinesis, scruffiness, and flamboyance. It should be observed that 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 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 form and personality, seems immediately fond of and affectionate towards the Eleventh in "The Day of the Doctor".
- Also averted in the audio story "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.
- "The Wrong Doctors" sees the Sixth Doctor teaming up with a younger version of himself. The older version of Six has by this point undergone quite a bit of a Character Arc and has mellowed considerably out as a result, and as such he finds his younger self's more unabashed and arrogant attitude absolutely intolerable.
- On the promotional site 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", an obvious reference to the Seventh. In the novel The Eight Doctors, 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 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 the Titan Comics mini-series Four Doctors, Twelve and Ten don't get on in large part because Ten is worried about just how he gets the extra incarnations to become Twelve, and Twelve is... well, series 8 Twelve, who's not the easiest person to get on with so Eleven acts as mediator. However, Twelve averts this with Nine, who he describes as being nothing less than "fantastic".
- In "Heralds of Destruction", a Titan Comics mini-series written by Paul Cornell, the Third Doctor meets his immediate predecessor and much bickering ensues, as it did when they first met. Ultimately averted in that it turns out to be would-be dictator Ramón Salamander impersonating the Second Doctor to steal TARDIS technology.
- There is a series of three Big Finish stories featuring two incarnations of the Master, the decayed Geoffrey Beevers one and the bald Alex MacQueen one. They attempt to kill each other a few times (with the future Master having access to a device that would prevent killing his past self from also killing him) before they team up. But even when they do, they don't get along for reasons that are purely practical (as the Seventh Doctor points out, there can't be two Masters, it is in the name) as well as personal (twice Beevers!Master kills people before MacQueen can make a pun about their death, irritating him to no end). The MacQueen version states that if he has to be stuck with a past version of himself, he'd have preferred "the snake" (Eric Roberts), or "Mr. Velveteen" (the Ainley version) and talks about how fun it was when it was all 'pointy beards and Nehru jackets' (the original Delgado version).
- In The Flash (2014), Savitar, the Big Bad of Season 3, is revealed to be a psychotic future Time Remnant of Barry himself, resulting from a Stable Time Loop. It turns out that future Barry created a host of Time Remnants of himself to fight Savitar, who let one live to eventually turn into him. This Time Remnant was eventually driven insane after Team Flash rejected him for not being the "real" Barry Allen, ultimately taking up the mantle of Savitar to get revenge against Barry and the team.
- In Fringe, especially in season 5, Walter fears becoming the man he used to be before William Bell removed those pieces of himself. Those pieces had to be reinserted in Letters of Transit as Walter's brain had become damaged due to spending years in amber.
- In an episode of Hercules: The Legendary Journeys, 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 Bruce Campbell hates someone who looks just like him.
- Game of Thrones: Although no time travel is involved, in Season 6 Sansa remarks to Jon that she hates how naive she used to be and regrets how she took her home and family for granted. She also feels bad for being "an ass" to Jon.
Sansa to Jon: Don't you wish we could go back to the day we left? I want to scream to myself "Don't go, you idiot."
- Ted of How I Met Your Mother damns his and Marshall's past selves for not making a decision on the apartment.
- Legends of Tomorrow:
- Dr. Martin Stein meets his young self from 1975 and instantly starts to dislike him, calling him arrogant and complaining about him smoking pot and eating fatty foods. When Jax confronts him about it, Stein admits that he knows he's complaining about himself but can't help it. He also doesn't like his past self having the hots for Sara Lance, especially on the day he's supposed to meet his future wife. In a later episode, he berates his younger self (who has deduced who the older Martin is since their original meeting) for ignoring his wife in pursuit of science. That bit of advice has unexpected consequences when Stein returns to the present and finds he suddenly has a daughter in her thirties.
- Mick Rory also isn't very fond of his teenage self when he's brought into protective custody on the ship. He doesn't try to hide his hostility - or his approval when Sara's younger self slaps the kid for trying to rather creepily hit on her.
- Inverted with Leonard Snart, who seems very fond of little Leo, still innocent before his father goes to prison and comes out bitter and abusive, forcing his son into a life of crime.
- Played straight with Damien Darhk, who ends up facing off against his no-nonsense assassin self from The '60s.
Damien Darhk: I am going to kick my ass!
- In the American version of Life on Mars, Sam is afraid of talking to himself as a child.
- Mystery Science Theater 3000. In one episode, Crow plays with the Timey-Wimey Ball to tell his past self of 30 minutes ago to not convince Mike to quit his temp job. It escalates into an argument, with Crow muttering about what a jerk he was 30 minutes ago.
- Once Upon a Time:
- Prince Charming 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 Emma.
- On The Orville episode, "Tomorrow, and Tomorrow, and Tomorrow", a temporal accident causes Kelly's self from seven years earlier to appear on the ship. Present!Kelly is soon annoyed by how her past self is judging her not by all she's done (like becoming first officer on a flagship) but by not having her own command by now as she always promised herself.
Kelly: Every mature person has to make peace with the fact they used to be dumber. But they don't have to look that proof in the face.
- Thoroughly and completely averted in The Outer Limits (1995) episode "A Stitch in Time". After saving her 15-year-old self from the rapist who kidnapped her, Dr. Theresa Givens is delighted at having spared that version of herself the trauma that she experienced, allowing her to lead the normal life that she was denied.
- Red Dwarf:
- In the 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, inverted in Out of Time.
- In a later time-travel episode, "Give and Take", when the crew are taking a lift in the past, and the lift reports that Past!Rimmer is getting annoyed waiting for it, Present!Rimmer says "Ignore him, he's an idiot!" When Cat says "But he's you", Rimmer replies "He's past me. Present me is a lot smarter." They've travelled back three days.
- Samantha Who? was about a woman with amnesia, who as she put her life back together was appalled to discover what an awful person she had been.
- In the Sir Arthur Conan Doyle's The Lost World 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 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.
- In the Star Trek: The Next Generation 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 Bar Brawl against Nausicaans (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 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. Q shows that if he hadn't been that arrogant young man, he'd never have become the kickass captain we know and love.
- He also expresses disgust for his skirt-chasing, two-timing ways.
Q: You never told me you were such a ladies' man.
Picard: I wasn't. I was a puerile adolescent, who allowed himself to be led by his hormones instead of his head.
- He also expresses disgust for his skirt-chasing, two-timing ways.
- In the Star Trek: Voyager finale "Endgame", when Admiral Kathryn Janeway from the future (who has admittedly become an Insane Admiral 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 chewing her out.
- The Twilight Zone (1985): In "The Girl I Married", Ira Richman is confronted with the spirit of The '60s version of his wife Valerie and spends several days with her. He later learns that Valerie has been doing the same thing with a younger version of him. As soon as all four of them are in the same room, the older Ira and Valerie realize that they find their hippie selves irritating. Ira tells them that they have no idea what real love is, saying that it is about commitment. He also finds his younger self's mellow attitude very grating. After they disappear, Valerie has a hard time believing that they were ever really that arrogant, naive, and pompous.
- The Garfunkel and Oates song "29/31". It follows a woman at the ages of 29 and 31; her 29-year-old self is an idealistic Naïve Everygirl while her 31-year-old self is a cynical Deadpan Snarker, having realized her life didn't go as well as she expected it to. Her older self (played by Riki) 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 George Jones 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.
- Relient K's song "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."
- Taken from the other perspective in the song "Future Me Hates Me" by The Beths
Future heartbreak, future headaches
Wide eyed nights late lying awake
With future cold shakes from stupid mistakes
Future me hates me for, hates me for
- Dead Ringers: Reunion counts on this happening with Germaine Greer of 2018 meeting Germaine Greer of The '60s. Sure enough, the elder Greer mocks her younger, proudly feminist self as a hippie who needs to get laid. Conversely, '60s Greer is horrified and disgusted at her older self's sexism, and storms out of the show.
- This is how Omnitron-X feels about his previous iterations in Sentinels of the Multiverse. After constantly failing to defeat heroes, Omnitron, a Self-Aware Robotics Factory intently studied his previous battles, and realized that the heroes were fighting at increased capacity when people were in danger, so to be more powerful, he built himself a Morality Chip to tap into that surge of strength... Resulting in him becoming The Atoner and using Time Travel to Set Right What Once Went Wrong. In a nice example of Gameplay and Story Integration, the game tags Omnitron and Omnitron-X as Arch Enemies.
- Characters in the videogame adaptation sometimes have unique game-start dialogue, and the reformed villains from the OblivAeon expansion get this with their villainous equivalents, even if they're not actually archenemies. In particular, Luminary - the Enemy Mine version of Baron Blade - constantly talks shit about his past versions.
- In the last set of levels of Crash Bandicoot 4: It's About Time Cortex decides to use the quantum masks to keep himself from creating Crash. However, all efforts to warn his past self fall on deaf ears with his past self calling him an imposter and ignoring everything he says.
Cortex: Do you have any idea how stubborn I used to be?
Aku Aku and Coco: Yes.
- In Spellforce: The Order Of Dawn, the Big Bad is the past version of the Big Good. Naturally this relationship applies. At the end of the game, the Big Bad undergoes a HeelFace Turn and goes back in time to stop his past self from causing The End of the World as We Know It. This leads to a Stable Time Loop, wherein he becomes the Big Good.
- World of Warcraft:
- The "Mystery of the Infinite" quest 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.
- 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.
- In the War of Thorns, Sylvanas Windrunner is questioned about how she had fallen so far. A dying Night Elf recalls that she had been a defender of her people, not a wanton destroyer. Sylvanas, who had suffered greatly at the hands of Arthas and the Scourge, who was shunned by the only loved ones she had left, became so jaded that she retorts that the person she remembers was a fool.
- The "Mystery of the Infinite" quest 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:
- BlazBlue: Hakumen has renounced his old identity as Jin Kisaragi. He considers killing his "past incarnation" to be atonement for his/Jin's sins.
- In City of Villains, one villain "morality mission" has you meet three future versions of yourself, two of which think you're an idiotic weakling. The third is The Atoner, whose pleas for you to do the right thing you ignore.

- Saints Row IV sees present-day Shaundi come face-to-face with the Shaundi from Saints Row 2. The two don't get along: present-day Shaundi thinks past-Shaundi is a useless, drug-addled, promiscuous load, while 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 Sam & Max: Freelance Police 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.
- Raziel, one of the protagonists of the Legacy of Kain series, has a long, complicated backstory with a heaping helping of Amnesiac Dissonance.

Traveling through time and discovering that he was actually a Jerkass Knight Templar changes his mind - violently. In fact, he is his own murderer.
- Jak II: Renegade:
- Young Samos and Old Samos do not get along, to the point where Daxter has to mediate.
- Averted with Young Jak as he's one of the few people that angry Older Jak gets along with.
- In JoJo's Bizarre Adventure: Eyes of Heaven, Time Travel means that several characters get to meet themselves from previous parts. When Old Joseph meets his Battle Tendency self, they immediately start throwing shade at each other, with Young Joseph considering his future self an old fart and Old Joseph considering his past self a brat. Old Joseph also makes sure to step in during the argument that ended up getting Caesar killed to scold himself for being too overconfident. On a lighter note, if Old Joseph ever fights with Young Joseph in his Tequila Joseph skin (based on his ill-conceived attempt to infiltrate a Nazi base), his quotes will have him horrified to be reminded of his past shenanigans.
- Bioshock Infinite has Father Comstock, the Big Bad 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 Magical Girl Lyrical Nanoha A's Portable : The Battle of Aces has Fate confronting a copy of herself based on her memories of her Dark and Troubled Past. The match revolves around her trying to convince her angst-filled past copy that, eventually, everything will become all right.
- In Mario & Luigi: Partners in Time, 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 team up, but neither one ever figures out the other's identity.
- In Bayonetta, Bayonetta thinks Cereza is an annoying little brat, but gradually warms up to her. However, it isn't until later that she learns Cereza is her younger self. Since she has amnesia, she didn't remember meeting her future self. Meanwhile, Cereza meeting her future self was what inspired her to stop being a scaredy-cat and grow up to be a badass.
- In The Legend of Heroes: Trails of Cold Steel II if you get Machias' dorm event, he considers his attitude when he first arrived at Thors (loudmouthed, bigoted hater of all nobles and everything nobility) "embarrassing," saying that even Millium was more dignified than he was and describes it as a time of his life he'd rather forget. Worse, he feels that on the inside he still hasn't changed. He chooses to continue to try his best to change.
- In Prey (2017), if you kill Alex Yu during the simulation of the Talos I outbreak that constitutes most of the game, the real Alex doesn't hold it against you when you meet him at the end. The simulation of him was only a minor exaggeration of what he used to be like before his Heel Realization, so he completely understands why you distrusted and attacked him.
- In God of War (PS4), Kratos is deeply ashamed of his past as the Ghost of Sparta. He can never truly erase his past either since he still bears the scars of his past life such as the ashes of his dead family grafted on his skin and the burn marks on his arms from the Blades of Chaos. When he settled in Midgard he tried his best to start anew, quietly starting a new family and burying the Blades of Chaos beneath his house. Throughout the game, he reacts to reminders of his bloody past with disgust and shame. In one scene he comes across a jar decorated with an image of the Ghost of Sparta standing atop a pile of bodies screaming at the heavens. Kratos stares at the jar for a moment in horror before hurling it at the ground to keep Atreus from seeing it though Atreus still sees the image of his father as the Ghost of Sparta on a large piece of the jar. One of the reasons Kratos' relationship with his son is so strained is because he doesn't want his son to know his past. It's only at the end of the game that he realizes he shouldn't keep hiding the truth from Atreus anymore.
- During the Coda of Tactics Ogre, should you take Ozma with you and have her fight herself, Present!Ozma will not have very many nice things to say about herself back then. Because Ozma had learned the truth of what was going on with Valeria and what really happened with Hobyrim and Balxephon, she didn't like what she once was.
- In Mortal Kombat 11, with the Goddess of Time being involved, it happens a few times:
- Hanzo Hasashi (aka Scorpion) hates how much his younger self was focused on getting revenge, and attempts to convince him to let go of the past a few times.

- Erron Black recognizes that he was "a bit much" when he was younger, and even admits it to Kotal in one introduction. His interactions with his past self come across as prickly at best.
- The revenants, especially Liu Kang and Kung Lao, especially hated their past selves for being too 'naive' and trusting with Raiden, who ended up responsible for their revenant status. Their heroic selves, however, are not amused at how fragile their evil selves' faith and conviction are and completely resisted the revenants' attempts to sway their trust from Raiden.
- In No Straight Roads, Tatiana does not have any fond memories of her time as Kul Fyra, the face of the in-universe band the Goolings due to her inability to keep them from falling into infighting and breaking apart. Such is her dislike of her past that she ended up becoming a Control Freak as the CEO of NSR, rejecting Bunk Bed Junction at the audition simply because of her anti-rock bias as well as banning rock from Vinyl City in favour of EDM as a result of Mayday's outburst towards her. In the end, she eventually learns to get over her past after teaming up with B2J to stop a falling satellite from destroying the city.
- In Fire Emblem: Three Houses: this trope occurs sometimes in the timeskip:
- In his A-Support with Byleth, Lorenz confesses that he is ashamed of his previous personality, he has since been stiving on a much more ideal version of how a noble should act.
- Marianne is shocked and horrified at how arrogant and foolish her younger self was; even in spite of her nonexistent ego. She was ashamed to act as if death meant nothing to her, never caring whether she lived or died. After seeing many people die around her, she begins to realize how precious life truly was.
- RealityMinds: Kvena was isolated from others and developed a pessimistic outlook on life. She secretly hates Silvana for reminding her of her past shut-in self.
- Fate/stay night:
- This is how Archer feels about Shirou Emiya. 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 and he wants to be free of it. Saber warns Archer that since Heroic Spirits exist outside of time, killing Shirou will not erase him, but he roars that if there's the slightest chance it will work and undo all his pain he will do it, and even if it doesn't work, he will at least rid the world of Shirou Emiya the screwup. Depending on the route, Shirou addresses his flaws in various ways, but nonetheless, Archer eventually dies peacefully trusting that Shirou will not become like him.
- There's a hilarious scene where Shirou sees Rin's memories. He does not recognize his own child self and says the boy looks like a total moron.
- In the [RE]turn mode of Sunrider Liberation Day, Kayto quickly grows exasperated with how his past self stubbornly refuses to even consider the possibility that his Love Interest Chigara is a Prototype spy and is going to kill everyone at the Liberation Day ceremony and writes off all evidence to the contrary as part of a Prototype plot to drive a wedge between the members of the Sunriders crew. Kayto even ends up sympathizing with his Number Two Ava for having to put up with his past bullheadedness,note and gives her a heartfelt apology during her route.
- In Death Mark, this is a possible reaction of the protagonist to finding out that they are indirectly responsible for all of the violent spirits that had been plaguing the region. In his original identity, Masamune Kujou, he became aware that the sacred statue suppressing the power of an evil cursed doll was weakening. To restore the statue's power, he removed it from the doll and placed it inside a shrine to purify it, but this purification would take a month to complete. As a result, the doll was free to spread its evil for a month, striking Masamune with a curse that rendered him an amnesiac, killing Masamune's sister, and creating vengeful spirits that killed numerous innocents. Upon recovering his memories, the protagonist has a choice of either seeing the consequences of his actions as a horrible but necessary step to re-sealing the evil doll or despising his past self for the death and suffering.
- Red vs. Blue: Singularity shows that Agent Carolina feels like this with regards to her time in Project Freelancer, to the point where her Labyrinth Illusion is herself from that era. When she meets Illusion!Carolina, she yells at her past self for being so obsessed with gaining her father's affection that she ignored the people who actually cared about her as well as being utterly callous to others such as Mark Temple, thus having them haunt her years later, all the while her father would never give her the time of day as he couldn't let go of his wife's memory.
- RWBY: An episode from the fifth volume features the characters discussing how they have grown since the fall of Beacon. While they don't exactly hate how they were prior to that monumental event, they are embarrassed by how they have acted since then. Examples include Ruby going against a Nevermore on her own, Weiss being cold towards everyone, and Yang recklessly charging in situations without giving a second thought to the aftermath.
- Subverted in The Last Days of FOXHOUND, where The Sorrow shows the amnesiac Liquid his past in order 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 Fans! pits the science fiction club against their book 1 versions, and nearly all of them have this reaction.
- Karkat gets into arguments with his past and future selves so often that it's practically become a Running Gag. In one instance, 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. As the ridiculously small time periods involved indicate, it's not so much that he hates the reminder of "who he used to be", he just hates who he is.
- Jade gets sick of Jadesprite's sobbing pretty quickly. When she refuses to do the one thing that could probably accomplish her goal of going back to being dead, present Jade loses it and starts smacking sense into her, literally. It gets stranger: Since Dream Jade went back in time 13 years after dying, Jadesprite is technically older than Jade, but her personality is noticeably more flawed.
- Vriska is soured on her former Attention Whore Glory Hound 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 she meets the Retcon version of herself who never died and went through the Character Development 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.
- Nearly every character who interacts with their own past/future self (which is pretty much all of them) finds said past/future self to be hopelessly stupid/unbelievably arrogant. Dave is the one notable exception; he seems to find his past and future selves to be pretty chill dudes...luckily for him, since as the Hero of Time for his session, he runs into himself a lot.
- A non-Time Travel example occurs in The Dragon Doctors when Kili and Greg go to part of the Spirit World 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 Totally Radical headbanger self.
- Shortpacked!: Modern Age Batman meets Golden Age Batman. And yes, Golden Age Batman really was that much of a dick.

- From Narbonic: Dave to Dave prime:
Dave: "I'm your future, and I hate you. I'm going to electrocute you now."

- In Sinfest, Fuchsia is terrified after she has a flashback to her pre-HeelFace Turn days.
- In one arc of Full Frontal Nerdity, 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 Munchkins, much to Nelson, Lewis, and Shawn's dismay.
- Future Stein appears to feel this way about his younger counterpart in Frankie and Stein.
- The main character of TwoKinds, Trace has been suffering from amnesia since the start of the comic, which is good since he was kind of 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?
- In Sonic the Comic Online! this is Sonic's reaction to meeting his past self. It leads to this conversation when they come across a statue of Johnny Lightfoot that was built after his death:
Past Johnny: Look — there's a PLAQUE on the statue.
Past Sonic: Heh, probably says "JOHNNY LIGHTFOOT — PROFESSIONAL SIDEKICK".
Present Sonic: YOU CREEP! Johnny was more of a hero than you'll EVER be!
- Magical 12th Graders: 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.

- In "Time Travel", a guy travels back to give his teenage self advice, but is too disgusted by what he's doing, namely posting opinions on women on a Magic: The Gathering forum.
- The first time Bun-bun escaped Timeless Space in Sluggy Freelance, he developed amnesia and couldn't remember how he got out. So his second time there he figured his best course of action was to follow his past self out. Unfortunately he was such a pain in the ass that he ended up whacking himself in the head, causing the amnesia. That wasn't even two different versions of him, as both had the same kind of personality already — a misunderstanding led them to be at odds about something, and, both being the same, neither would back down one bit.
- In Kill Six Billion Demons, Cio used to be a powerful and tyrannical ebon devil named Yabalchoath, who was feared by everyone for being The Caligula. Eventually, the angels and her own abused slaves rose up and killed her, causing her to reincarnate into a harmless blue devil. Now Older and Wiser, Cio despises Yabalchoath and feels tremendous guilt for her behavior, speaking of her past life with nothing but scorn. It's noted that she could potentially regain her ebon devil powers, but she refuses to do so expressly because she's scared of being Yabalchoath again.
- In The Rant of El Goonish Shive, Dan sometimes berates his past self for his decisions like making Grace cry. That said, he also recognizes the futility of this.
Dan: Granted, not a lot is accomplished by being mad at ones past self. The healthiest thing is to accept ones past mistakes and move on. Of course, Im an artist and get to see a visual record of such things, SO I WILL NEVER MOVE ON. EVER.
- In the "Memories of Youth" strip (January 13th, 2011) of the online comic Nedroid, Reginald is about to commit Seppuku when Beartato stops him. Reginald explains, "...I just remembered all the embarrassing things I did as a teenager". Beartato tells him to move on from the past, but a thought balloon pops up in Reginald's mind wherein he remembers himself as a teenager at his crush's locker, about to give her a Mixtape of Love. Present Reginald then attempts to drink poison.

- Rose from Wonderlab, after discovering the full extent of the suffering caused by the Wings' actions, loathes the kind of person they were in the past (i.e, a spoiled rich kid who was perfectly content with the status quo)
- Here's one artist who expresses this sentiment rather succinctly.
- This is one of the older Joes' reaction in the CollegeHumor video "Looper Has Sex with Himself" when the younger Joe refuses to give the older ones a blowjob.
- Crash Course: 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 favor of pedantic sniveling in which no-one loses or gains anything of value.
- Glove and Boots: In their "10 Reasons Why Time Travel is No Good" the first reason they give is that you can meet yourself. Mario demonstrates by time travelling and meeting his past self and future self.
Past Mario: I'm wearing this two-prong! I'm wearing this two-prong!
Present Mario: Oh man! I thought I used to be cool but I was stupid!
Past Mario: THIS IS THE BEST!
- The Nostalgia Critic does this once in a while. Case in point, the Christmas with the Kranks review.
- Anime America began a series in which they look back at videos made years before. For the first episode, Robyn looks back at Top 10 Characters That Need to Go Back to the Drawing Board". She criticizes her past self for having no chill, questions why she put Soul Eater's Excalibur on the list (present-day Robyn admits that she now accepts that character; ditto for Bobobo-bo Bo-bobo who appeared as a runner-up) and pokes fun at her past self's pronunciation of "manga".
- React has special episodes where the reactors have to see themselves in past episodes as Kids\Teens or their audition tapes. Cringing ensues, caused mostly by looks ("Thank God for puberty!") and awkward behavior.
- The Music Video Show has this in the 100th episode where the third season host say this to the second season host.
- Fate/Stay Night: Unlimited Blade Works Abridged: Archer hates Shirou, same as in canon, but it's Played for Laughs more.
- On the Dream SMP, this is Played for Drama, where Ghostbur hates being reminded of the things "Alivebur" did, and will shut down anyone who tries to talk to him about it. Despite not remembering what he did in life, he's aware that his past self was a horrible person, and is quick to reassure anyone who mentions it that they're not the same. He's even told Phil, his father, that one of the happy memories he remembers from his life was when Phil ran him through with a sword.
- In American Dad! 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.
- An episode of The Angry Beavers has Norb develop amnesia or damnesia as the episode calls it and becomes "Troy". Troy becomes horrified after seeing a video of himself and wonders how Dag could like him after all the times Norb mistreated him.
- 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.
- Variation in the Avatar: The Last Airbender episode "The Ember Island Players", wherein the main cast watch a play about their adventures. While all of them (sans Sokka and Toph) are irritated by their portrayals, Zuko's anger comes from the actors comically exaggerating all of his worst actions throughout the series, describing it as taking every mistake he's made and throwing it right back in his face during the intermission.
- Ben 10: Ultimate Alien: 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.
- Inverted in the original series episode "Ben 10,000", where the 10-year-old Ben finds his Future Badass self very boring and rude to everyone and helps him loosen up and remember how he can have fun and be himself and be a hero at the same time. Future Ben himself doesn't seem to like his younger self either (at least before taking his advice) but this is less of an example of this trope and more of an example of Hates Everyone Equally which, again is another reason why young Ben seems not to like his older self.
- Dark Danny from Danny Phantom, 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.
- Goes both ways in one Drawn Together 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, realizing what a jerkass future Hero is, retaliates and arranges for him to be arrested. 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 Duck Amuck, the animator deliberately misaligns the tracking of the film so two frames of the film are temporarily visible. Daffy then proceeds to get into an argument and fist-fight with the version of himself from one frame (1/24th second) ago.
Daffy 1: Listen to bub, if you wasn't me, I'd smack you right in the puss!
Daffy 2: Don't let that bother you, jack!
- A Running Gag in 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. Though there is one exception in "Bender's Big Score".
Bender-2: Hey! Who are you?
Bender-3: (dressed in a tuxedo) I'm Bender from way at the end. I came back to put this rub-on time code on Fry's ass.
Bender-2: So, what are you now, a butler? "Spot of tea, please, jerkwad!"
Bender-3: It's called class, you yokel. Now if you'll excuse me, I have a buttocks to tattoo.
- In the 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. The difference in time between the two is a matter of hours.
- In Generator Rex, the eponymous character, suffering from chronic Laser-Guided Amnesia, 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 Casanova before he met Rex, and reverts to this when he loses six years of memory. In an odd inversion of the trope, Six decides to try turning his life (back)around when he sees the admiration Rex had for his past "future" self.
- Justice League:
- Vandal Savage in the 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 Superman back in time, Savage tells Superman that he must stop Savage's past self no matter what.
- In the Unlimited episode "The Once and Future Thing: Time Warped" 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 and instead simply beating information out of him. This leads to an amusing Good Cop/Bad Cop 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.
- Justice League Action: Downplayed example in "Time Share". Blue Beetle and Batman travel to the past to prevent Chronos from causing havoc with Batman's past. The two end up encountering the past Batman, who is living out of his car, without his Grappling-Hook Gun and saying cheesy lines and posing. Present Day Bats is clearly embarrassed by this phase of his career. Especially when the younger Batman does the classic 'I am the night' rooftop pose, mere minutes after Batman told Beetle that heroes do not pose. Blue Beetle makes sure Scarab took a picture.
- In the My Little Pony: Friendship Is Magic episode "It's About Time", while it isn't hate, Twilight is frustrated upon the realization that the Stable Time Loop she just created could have been avoided if her past self had just shut up for five seconds.
- After the Time Skip in ReBoot, as a result of his failure to protect Mainframe when he was a kid, Matrix expresses constant dislike of the memories of himself as a kid. During a dream sequence 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 an Annoying Younger Sibling. The relationship is eventually inverted. Despite initially worshipping his future self, copy Enzo grows to dislike Matrix's bitterness, while Matrix tries to regain some of the idealism of his youth.
- In Rick and Morty, Rick unwillingly teams up with a memory of his younger self during a Journey to the Center of the Mind and the two constantly trade verbal barbs with one another as his younger self is put off by what a pessimistic old crank he becomes, while his current self looks down on his past idealism.
- Grouchy Smurf in The Smurfs: A Christmas Carol : "Past me is so annoying."
- South Park:
- In the "Go God Go" duology, Cartman tries warning himself not to freeze himself by using a phone designed to make prank calls to the past. 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.
- In the Season 21 finale, Heidi reminisces about the early stages of her relationship with Cartman, and is disgusted by how nice and caring she was back then. However, this leads to her Heel Realization, and HeelFace Turn at the end of the episode.
- Steven Universe: In the 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.
- In Super Robot Monkey Team Hyperforce Go!, the Skeleton King has nothing but contempt for his past self, the good-hearted Alchemist who created the Hyperforce specifically to oppose the monster he was doomed to become, whom he derides as a sentimental weakling.
- People who have been heavily bullied often develop this mindset, 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.
- Especially with Transgender people. Imagine being bullied. Then imagine having a false persona, repressing everything you are to the point where you're driven to self-harm by your existence *without* the bullying, being the one that was being bullied.
- Even those who haven't been bullied will try to maintain a dignified reputation by hiding Embarrassing Old Photos which show that they were just regular kids. Bonus points if the photos show the kid version of the dignified person having Filthy Fun.
- One commentator on Know Your Meme's article on Katy t3h PeNgU1N oF d00m.
Crimson Locks: Oh, hello, past self. How unpleasant it is to see you again.
- Most, if not all, artists experience this when looking through their old art. As JelloApocalypse said in "Welcome to Webcomics":
Don't worry about how bad your first page looks, because you'll end up hating it for years no matter what you do.
- Checking Facebook Memories (previously On This Day), which brings up all the posts of an user on the same day throughout the years, can cause cringing as people look back at the things they said and shared.
