Hourglass Plot

Go To
Bookends of the first and last acts of the Batman: The Animated Series episode "Joker's Favor".

A Story Arc in which two characters or groups slowly, and involuntarily, swap their positions in life. These positions are usually social (who has high-status, who is popular), economic (who is rich), and most of all, moral — who is decent and who is a ruthless bastard. The swapping often leads to escalation — the new poor person is poorer than the old one was, or the new amoral one is much nastier than the old one was.

The pathos from the Hourglass Plot comes from how neither character learns from the situation — they act just the same to each other as they did before, but with roles reversed. Particularly cruel shows will create an infinite-loop Hourglass Plot, where two hostile characters keep swapping positions and treating each other as badly as ever. In rare cases, such plots will involve the characters barely interacting with each other... a pure comparison of one person's rise to another person's fall.


Lucky characters will get a "Not So Different" Remark moment and actually learn from it. Compare: Prince and Pauper, Perspective Reversal, Full-Circle Revolution, Swapped Roles, Became Their Own Antithesis for when there's only one character and now corresponding switch, "Freaky Friday" Flip for an especially literal case, Just the Introduction to the Opposites for when there is no justification for it, and Perspective Flip for when it's a retcon instead of a plot development. Compare and contrast: If You Kill Him, You Will Be Just Like Him! and You Kill It, You Bought It. Caretaker Reversal is a subtrope.

Since explaining examples of this trope requires full knowledge of a story's plot, beware of unmarked spoilers.

    Anime & Manga 
  • Attack on Titan:
    • Christa/Historia and Ymir start off with very specific roles: Christa is the resident "goddess", viewed by everyone as an epitome of pure altruism and selflessness, while Ymir carries herself in an utterly self-interested and cynical way, despite falling in love with Christa. As the series progresses, however, their interactions gradually bring out all the past trauma in both of them, and they both have diametrically opposite effects on each other: Historia becomes a lot more grounded, even ruthless at times, particularly after claiming the throne of the Walls, while Ymir ends up sacrificing herself for members of her squad not once, but thrice.
    • Eren has this with several characters:
      • Eren and Armin start off with Eren as the one who believes that he will save the world from the titans, and Armin being the more reserved, cautious one who has absolutely no confidence in himself or his actions. As they go through the series, Armin's plans repeatedly succeed and he slowly grows more confident in them while Eren's plans repeatedly fail and/or are only successful after an immediate disaster. This culminates in Chapter 84 when Eren demands that Levi give Armin the serum and save him because he believes that Armin will be the one to save the world, not Eren himself, since Armin still remembers the dream they had of seeing the outside world. Ironically, after the Time Skip Eren deems Armin to be worthless for not coming up with a proper plan. Eren himself is praised by the public for taking the initiative to resolve the Eldian crisis. For all his intelligence, Armin failed to understand Eren's master plan until it was too late. Eren has to spell it out to him and that is after he unleashes all the Wall Titans to destroy all civilization outside the island.
      • This now also applies to Eren and Reiner, as Eren is seen as the villain by everyone who isn't on the same side of the main characters. Reiner, and the rest of Marley, are only viewed in a negative light by the main characters. Eren points this trope out to Reiner, saying "I'm the same as you".
      • He also has this dynamic with Mikasa: Eren is initially motivated by his desire to free humanity from the Titans, and Mikasa joins him for the sole purpose of protecting him, everyone else be damned. After the Time Skip, Eren is willing to betray his friends' trust to attain his goals and ends up alienating them, while Mikasa grows warmer towards her squadmates and finds herself estranged by Eren's newfound ruthlessness.
      • And interestingly, with the Colossus Titan. At first, Eren is one of the protagonists and the Colossus Titan was seen as the greatest threat. Things go full topsy-turvy much later, now the Colossus Titan is one of the protagonists in the form of Armin, and Eren himself has become the Big Bad with his plan to kill everyone except for the people of Paradis Island.
      • Also has this with his actual half-brother, Zeke Yeager and his father Grisha Yeager. Eren was regarded as one of the key opponents against the Beast Titan, the true threat beyond the walls, and the latter tried to save Eren from being 'brainwashed' by their father into committing for his cause, while not knowing Eren joined the fight from his own will. After the Time Skip, Eren reveals himself to be the one actually manipulating his father, making him massacre the Reiss Family and feeding himself to Eren, but also reveals himself as the true threat by releasing the Wall Titans, but Grisha also begs Zeke to stop him from destroying the world, which Zeke listens to.
  • Demon Slayer: Kimetsu no Yaiba: The overarching plot is about Tanjiro Kamado, a young man who joins the Demon Slayer Corps in hopes of finding a cure for his sister Nezuko, who was turned into a demon by Big Bad Muzan Kibutsuji. About two hundred chapters later Nezuko does get turned back into a human, but shortly afterwards a dying Muzan turns Tanjiro himself into a demon, making him the one who needs to be cured.
  • Dr. Stone: At the beginning of the series, Tsukasa Shishio's primary motivation is to find a cure for his terminally ill (brain dead) and comatose sister Mirai despite it being beyond modern medical science. At the end of the second story arc, Mirai is restored but immediately afterwards Tsukasa is fatally injurednote  and has to be rendered comatose note  until they can find a cure that's beyond modern medical sciencenote . Mirai even remarks on the situation, saying that Tsukasa spent years looking after her and now she'll spend however long it takes looking after him.
  • Higurashi no Naku Koro ni Gou has this happen with Satoko and Teppei Houjou: after finding out about his deaths in the "Groundhog Day" Loop due to him being an Evil Uncle, Teppei actually tries to become a decent person towards his niece, including buying her snacks and driving away a group of motorcyclists harassing her. Unfortunately, she has become a homicidal Yandere willing to kill anyone just so she can have her childhood best friend all to herself.
  • In Love Live! Sunshine!!, this happened with the third years; at the beginning Mari was more reserved and had to be convinced to become a school idol whereas Dia and Kanan were passionate about it. After having Performance Anxiety in Tokyo and being crushed, Kanan and Dia are more closed off and want nothing to do with school idols, while Mari enthusiastically supports Chika's endeavor.
  • In Macross Frontier, popular idol singer Sheryl Nome serves as a mentor to up and coming Ranka Lee, but later Sheryl becomes ill and as her popularity wanes, Ranka's soars to the point of becoming a heroine capable of using her song to scare away enemy aliens. Then it happens again when Ranka loses her will to sing and makes a Face–Heel Turn while Sheryl takes her place when it turns out she has the same power.

  • My Hero Academia:
  • Naruto: Kakashi starts as a shinobi who only cares about the mission, while Obito thinks that comrades are more important. After the battle of Kannibi Bridge, Kakashi becomes more concerned about comrades and puts them above the mission. Obito however, completely and utterly shatters at seeing the love of his life kill herself with his best friend's attack and is sent down the nihilistic path to becoming Tobi, who will sacrifice anyone and everyone for his mission. In fact, everything about Obito and Kakashi switched after that mission, including the Generation Xerox. Kakashi was originally Sasuke's counterpart and Obito was Naruto's. In the end, however, Kakashi became a kind, loyal shinobi of Konoha who becomes Hokage like Naruto, while Obito becomes a wanted criminal/terrorist who eventually makes a Heel–Face Turn like Sasuke.
  • Neon Genesis Evangelion: Shinji and Asuka start as the "shy failure" and the "confident Ace Pilot" and over the course of the series, Shinji racks up the most angel kills and Asuka has a breakdown because she doesn't. Shiniji later does revert back into the "shy failure", but that's a different matter.
  • In Phoenix: Karma, Gao begins as a ruthless bandit with a Freudian Excuse and Akanemaru is a simple artisan who winds up stabbed by him for no good reason. As the story progresses, Gao finds salvation through art while Akanemaru discovers his own ambition; by the end, both are changed men, and Gao is a sculptor whose talents outshine even Akanemaru's. The petty Akanemaru will not stand to be upstaged by Gao and throws away his own redemption, telling the tale of Gao's origins as the bandit who wounded him; Gao's remaining arm is taken as punishment and he is thrown into exile. However, Akanemaru himself dies in a fire trying to save his work, and as he dies, the Phoenix tells him that he will never be reborn as a human; Gao, on the other hand, manages to return to his art despite his disability.
  • Puella Magi Madoka Magica:
  • At the start of Rent-A-Girlfriend, Kazuya goes on his second date with his rental girlfriend, Chizuru, just so he can tell her off, but ends up having to visit his grandmother in the hospital, resulting in his family and Chizuru's grandmother (who is her only remaining family) being convinced they are a couple. Chizuru insists that they tell their families the truth and admit that they're not dating, but Kazuya insists that they keep up the lie. Later on in the story, Kazuya, noticing the toll that lying to everyone is taking on Chizuru, insists on finally coming clean, but Chizuru, not wanting to let her dying grandmother down, refuses.
  • In Simoun, the power dynamic between the Broken Ace Neviril and the Naïve Newcomer Aaeru completely reverses in the course of the series. Early on, Aaeru is the energetic and driven one in their relationship, pushing constantly to become Neviril's co-pilot and perform the ultimate Emerald Ri-Majoon with her; Neviril, meanwhile, is still reeling from the loss of her previous co-pilot and lover in a failed attempt at that very Ri-Majoon, so she spends most of the time moping or passively following her orders. By the final episodes, however, Aaeru's youthful idealism is broken and she essentially loses direction in life — and it is Neviril, finally recovering from her depression (with Aaeru's own help), who gives it to her again: namely, to perform that very Ri-Majoon Aaeru wanted and she didn't from the start.
  • In The Tatami Galaxy, for most of the series, the Unlucky Everydude protagonist is caught in a "Groundhog Day" Loop, and in every episode, Ozu, a screwball (who is illustrated to look somewhat "demonic"), arranges things so that the protagonist fails to achieve (often romantic) success, and looks bad. Eventually, it is revealed that Ozu's antics are motivated by a combination of his own romantic pursuits and genuine friendship toward the protagonist, and the protagonist has an epiphany wherein he rethinks some of his own behavior and realizes that Ozu is a true friend. At the end of the series, Ozu (now illustrated as normal looking) seeks the protagonist's aid for his romantic troubles, and the protagonist assumes Ozu's former role of good-natured troll.
  • Yu-Gi-Oh! VRAINS starts with Ai hunted down by the Knights of Hanoi and SOL Technologies before captured/saved by Yusaku and teaming up to fight the two groups. The final season has Ai turncoat and become the final villain while Café Nagi, the Knights of Hanoi and SOL Technologies team up to stop him and Yusaku was the one to end his life.

  • Watchmen: Rorscharch and Ozymandias exchange positions at the end. The latter calls the former a right-wing loony and the former regards him as a liberal hypocrite. As a young man, Rorscharch wrote gushingly about Harry Truman's decision to bomb Hiroshima and Nagasaki as the wisdom of Well-Intentioned Extremist thinking. But he's horrified when Ozymandias comes around to it, and does it for real. However, it needs to be stated that Rorscharch's code is all about the rules. In his mind, Truman had authority to do what was needed, since he was President of the US and Commander-in-Chief while Ozymandias did not have any authority to do something similar.

  • Both 21 Jump Street films have this trope in spades. In high school, Schmidt was an unassuming nerd who was bullied by the cool bully Jenko. After becoming friends and partners, they are sent undercover as high school students where they at first retain their initial behaviors from before. However, Surprisingly Realistic Outcome with their new classmates: Schmidt is now seen as cool because of his pleasing and studious nature while Jenko's care-free attitude is a turn-off for the more responsibly-minded generation he has to mingle in. In doing so, he falls in with the nerd crowd and becomes an outcast himself.
    • 22 Jump Street has this flipped around again: Jenko's alpha jock status allows him to become a popular football player while leaving Schmidt behind.
  • In the Anacleto: Agente Secreto movie, the main character is a lazy bum who wants to spend his free time watching movies at home, while his girlfriend wants to go out and have adventures, so she dumps him. At the end of the movie, the main character (who has learned how to be a super-spy) wants to go out and have adventures, but the girlfriend (who has lost an eye and ended up in several death-threatening situations during the movie) only wants to spend her free time watching movies at home... and she dumps him.
  • Bad Genius has this happen between two of its leads, Bank and Lynn. At first, Lynn freely masterminds an exam cheating scheme at school while Bank flat-out refuses to let his classmate copy off of him, even for a hefty sum. By the end, Bank is banned from retaking the STIC and expelled from the school. He tries to blackmail Lynn into stealing the answers to the GATsnote  with her role in the heist, while Lynn, who was wracked with guilt and undergoes a moral epiphany, refuses and exposes the scheme.
  • The two divorcees in Woody Allen's Celebrity: Lee starts up wanting to immerse himself in celebrity journalism thinking that it will bring him success, while his ex-wife Robin is insecure on top of the neuroses the couple had.

  • At the end of "Creep", the female lead has taken the place of the homeless girl she saw begging at Charing Cross Underground station.
  • In the first half of Crocodile Dundee, New York City reporter Sue Charlton is a Fish out of Water in Australia with the eponymous Mick Dundee as her guide. The second half has Mick going with Sue to NYC, where Mick becomes the Fish out of Water with Sue as his guide.
  • Dead Poets Society: Todd and Neil's arcs. At the beginning of the film, Todd is shy, timid and hesitant to get involved with Keating's philosophy, while the outgoing Neil is the group's leader, determined to "seize the day" and is the one encouraging and supporting Todd. By the end of the film, it's Neil who is unable to stand up to the pressure on him and commits suicide, while Todd finds his voice, leads the boys to defy the school, and is ultimately the one to live out Keating's teaching.
  • DodgeBall: A True Underdog Story: The movie starts with White starring a Globo Gym ad on TV and Peter watching it and ends with Peter starring an Average Joe's Gym ad on TV and White watching it. In both cases, the person watching it looks and acts like a slob.
  • In the beginning of Dogma, Loki is portrayed as the more ruthless and reckless, wanting to go on one more divinely righteous killing spree before re-entering heaven, while Bartleby is the one who feels compassion for the humans and is more reserved. However, halfway through Bartleby snaps and becomes an Omnicidal Maniac bent on killing everyone, and it is Loki who is attempting to hold him back.
  • The Fly (1986) involves a Love Triangle in which the two male corners of it undergo this. At the beginning, Seth is sweet, timid, kind, and respectful to Veronica, while her ex-lover/editor Stathis is a Clingy Jealous Guy stalking and attempting to manipulate her into reviving their relationship. But then Seth has a Teleporter Accident (which indirectly stems from Stathis's treachery) that turns him into a human-insect hybrid undergoing a Slow Transformation on both physical and mental levels. The result is that by the end, Stathis is the one doing his best to help and protect Veronica while respecting her wishes, while Seth goes mad and becomes a literal and metaphorical monster who maims and almost murders Stathis and tries to fuse himself with Ronnie and their unborn child, whom only he wants to keep. This is a rare example of the trope in which the two men barely interact with each other; after Stathis's introductory scene they don't meet each other again until the climax/denouement, though each is aware of the other person's evolving role in Veronica's life. Moreover, Seth knows he is becoming the villain by the end but cannot stave off the Split-Personality Takeover, making matters that much more tragic.
  • Irreconcilable Differences: After Albert divorces Lucy, he lives in a mansion with Blake while Lucy lives in a small apartment. Later, after Albert's career goes downhill and Lucy becomes a bestselling novelist, Lucy buys Albert's mansion while Albert moves into a motel.
  • Juno and Mark. She keeps going over to his and Vanessa's house to get to know them better and see what kind of family her baby will have ("I just like being a piece of furniture in your weird life"), while his exposure to her and her teenage flippancy gives him second thoughts about his adulthood and eventually causes him to bail on his wife and the coming baby, to Juno's shock and dismay. His regression triggers her coming of age.
  • In the Marvel Cinematic Universe:
    • In Thor, the titular hero starts out as a vicious Blood Knight while his brother, Loki, is much more cautious and diplomatic. By the movie's end, Thor is much more peaceful and tries to reason with his enemies rather than plunging into battle, while Loki tries to demolish an entire world to achieve his goals.
    • Tony Stark is introduced as a fiercely independent businessman who plays by his own rules and despises government bureaucracy, while Steve Rogers is a patriotic working-class kid from Brooklyn who believes in self-sacrifice and jumps at the chance to serve his country in World War II. Accordingly, when they meet in The Avengers, Tony regularly chafes at authority and almost loses his spot on the Avengers, while Steve remains loyal to SHIELD from start to finish. But as the series goes on, both men's character arcs move in opposite directions. Tony becomes much more willing to submit to authority after one of his inventions grows beyond his control and endangers the world, while Steve becomes much more willing to question authority after he discovers a massive HYDRA conspiracy within the ranks of SHIELD. By Captain America: Civil War, their roles are completely reversed: Tony leads an effort to put the Avengers under government control, while Steve is the one who rebels against the government and fights to remain independent.
    • Captain America: Civil War has Tony recruit Peter Parker to help him arrest Rogers and the other anti-registration heroes, though Peter doesn't want to go to Germany and miss school and has to be blackmailed into it. After the battle, Peter thoroughly enjoyed the experience and wants to join the Avengers full time, while Tony, horrified by the fact Peter almost got seriously injured, feels that bringing him along was a bad idea and wants him to stick to the streets. Spider-Man: Homecoming features Peter trying to prove his worth to Tony while he steadfastly refuses to let him join. By the end, Tony has decided that Peter has proven himself and wants to make him an official member of the team. However, Peter decides that he'd rather stay a street-level hero and fight for the little guys that the Avengers can't and turns the offer down.
    • Black Panther (2018) has this happen with W'Kabi of the Border Tribe and M'Baku of the Jabari Tribe. In the beginning, during T'Challa's ritual coronation, W'Kabi is the most supportive of T'Challa's rise while M'Baku is the one to challenge him for kingship. When T'Challa fails in apprehending Klaue, W'Kabi wavers in his loyalty and brings in Erik (after he delivers him Klaue's dead body), seeking to be kingmaker in his rise after defeating T'Challa. M'Baku, in contrast, has his men rescue T'Challa after falling to the rapids, keeps him alive on ice, and eventually turns around to support T'Challa in his counter-coup against Erik's nascent reign. He even takes W'Kabi's place at T'Challa's right hand in court by the end.
    • In Thor: Ragnarok, Valkyrie is an aimless mercenary who crawled into liquor bottles to escape the trauma of being the Sole Survivor of the Valkyries, while Thor is still an unabashed hero who takes his place as the rightful king of Asgard. By Avengers: Endgame, Valkyrie has stepped in to lead the remainder of the Asgardians as Thor became a reclusive drunken slob during the Time Skip due to the guilt of failing to prevent the Snap and losing his entire family. Even after restoring the universe and defeating Thanos's forces, Thor decides to join the Guardians of the Galaxy and leaves Valkyrie as the rightful Queen of New Asgard.
    • Similarly, in Endgame, the story of Tony Stark and Peter Parker. In Avengers: Infinity War, Peter Parker died by Thanos's Badass Fingersnap, right in the presence of Tony, who absolutely broke down into despair next we see him in Endgame. In the climax of Endgame, however, Tony is the one to do the Badass Fingersnap to defeat Thanos and his army, and partly to safeguard Peter (and his daughter) from dying again. Tony later dies due to the Phlebotinium Overload due to the Stones' powers, dying in the presence of a despairing Peter Parker.
    • Also, Age of Ultron establishes the difference between the philosophies of Tony Stark and Steve Rogers. Tony wants to end the fight so he can go home and start a family with Pepper Potts, which he manages to accomplish in the first half of Endgame. Steve believes that a normal life for him is impossible due to being displaced out of time and seeks to fight evil to the bitter end, even contemplating going out with a Heroic Sacrifice. By the end of Endgame, it's Tony Stark who gives up a chance for a normal life to save the universe through a sacrificial play, and it's Steve Rogers who goes home (in the past) to spend the rest of his life with Peggy Carter.
    • Initially, Natasha Romanoff committed various crimes and murders when she was working with the KGB and it is Clint Barton who offers her a chance to atone for her mistakes by joining SHIELD rather than killing her. In Endgame, Clint becomes a ruthless killer after his family's death and it is Natasha who allows him to redeem himself for his crimes by joining the Avengers in order to resurrect everyone.
  • This was part of the Character Development between Neo and Smith in The Matrix and its sequels. Smith picks up human emotions and independent goals (which he doesn't like) while Neo finds himself as a "cog in the machine" with a pre-destined goal (which also proves to be a bit of a drag).
  • In the 2011 film One Day, based on the novel by David Nicholls, the two protagonists Emma and Dexter come from completely different backgrounds and life goals, with Emma starting out as a poor waitress after graduating from university and Dexter beginning as a successful television host. Over time, Emma gains success first as a teacher and then as a writer. Dexter goes on a downward spiral and ends up a poor divorcee.
  • Pet: The film begins with a disaffected man becoming infatuated with a beautiful writer he claims to have known in high school, going from Endearingly Dorky to Dogged Nice Guy to Stalker with a Crush, leading to his kidnapping her and locking her in a cage under the animal shelter where he works. Then halfway through the movie, he tells her he read her notebook, a stylized journal detailing confessions of her murders. Plural. He wants to "save" her, but she is reluctant to change and pushes in return, telling him that somewhere deep inside, he's like her. She escapes confinement, but by the end of the movie, she seems convinced that he is her soulmate. The "Where Are They Now?" Epilogue reveals that she is happily back with her ex, Eric, and is keeping him locked up in a nearby warehouse, visiting him to with food, affection, and Cold-Blooded Torture whenever her murderous impulses rise up.
  • In Primer, Aaron starts off as a family man and rather risk-averse (note the scenes where he worries about needing eye protection and warns his wife against using the first batch of ice from the new fridge). Abe starts off unmarried and rather more devil-may-care. Over the course of the film, access to a Time Travel-powered Reset Button makes Aaron become more aggressive and willing to take risks, and he eventually leaves his family. Abe, on the other hand, becomes increasingly worried about the side-effects of time travel and oddly protective of Aaron's family.
  • Serenity has Mal and the Operative gradually trading roles in terms of their beliefs and convictions. Mal is established throughout Firefly as an idealist so traumatized by the Browncoats' defeat in the Independence War that he tries too hard to suppress his belief in self-determination — even as it keeps shining through his facade. The Operative, meanwhile, is introduced as a secular fanatic who believes so strongly in the Alliance cause, he will sink to any depths to ensure its success. Then, over the course of the film, Mal's passion for liberty and his hatred for the Alliance are reignited (specifically, by Shepherd Book's last words and then by what the crew discovers on Miranda), while the Operative's beliefs are utterly shattered when he is Forced to Watch the Apocalyptic Log from Miranda by Mal.
  • Martin Scorsese's Silence features this dynamic between Fr. Rodrigues and Kichijiro. At the start the former is a brave and courageous priest and the latter is a Dirty Coward apostate pentitent who betrays him repeatedly. Rodrigues frequently feels that his duty to pardon Kichijiro repeatedly is insane, yet in the end after he has apostatized, it is Kichijiro who restores Rodrigues' (now hidden) faith by asking for confession, and on account of the fact that he's more inept at hiding crucifixes than the apostate Rodrigues, he ends up attaining martyrdom while Rodrigues dies as an apostate sellout. In effect, the seeming Judas becomes a Christ-figure while the man who starts out wanting to be Jesus, and resembling him, ends up becoming Judas.
  • A two-parter in Trading Places. In the first half, Dan Aykroyd and Eddie Murphy swap lifestyles. In the second half, they team up to bankrupt the decadently rich Duke brothers and get rich in the process.
  • In What About Bob?, Bob Wiley starts off all-but-paralyzed by his various neuroses, while Dr. Leo Marvin is a psychiatrist who's just published a best-selling self-help book. Bob's interactions with the Marvin family helps him overcome his fears and learn to interact with normal society—eventually marrying Leo's sister, becoming a psychiatrist himself, and authoring his own book. Leo, meanwhile, becomes increasingly irritated and unhinged in response to Bob (in part because he feared that Bob was replacing him in his family's affections) and ends up catatonic. Though seeing Bob's and his sister's wedding apparently cures him.

  • When Anansi Boys starts, Fat Charlie and Spider are Polar Opposite Twins; Charlie is a mundane, responsible, dull Butt-Monkey — while Spider is a Reality Warper confident carefree party animal who is everything Charlie never had the chance to be and more (To the point that Spider isn't actually Fat Charlie's brother, but his magical trickster side literally severed out of him. And while Fat Charlie isn't actually fat, he is kind of soft, and Spider is slimmer than he is. As the story goes, Charlie becomes more confident and bold and more in-touch with his half-god side — while Spider learns about responsibility and caring for others and gets to experience being basically powerless for the first time in his life. By the end of the story they are on more-or-less equal footing, but with Charlie being the more confident twin and the more powerful Reality Warper (due to his affinity to Magic Music). By the end, Spider settles down and starts running a restaurant, growing fatter in the process. While Charlie becomes a singer and grows thinner. A case of Hourglass Plot where although the characters still switch places, their situation is less extreme compared to the initial one.
  • In Animorphs #49, Tobias notes the sad irony between him and Jake: Jake is now effectively orphaned, his whole family having been infested by the Yeerks, just as parentless Tobias rediscovers his long-lost mother.
  • In Best Served Cold, Monza is introduced as a cruel and amoral borderline Villain Protagonist and in pursuing revenge on the men who betrayed her and killed her brother, enlists the help of Barbarian Hero Shivers who had left his home in the North as part of a quest to leave his old life behind and become a better man. Initially, Monza belittles Shivers' scruples and acts as The Corrupter, but as the story progresses, Monza starts to feel guilt and flashbacks reveal that she isn't/wasn't such a bad person in the first place, while at the same time, Shivers increasingly loses interest in reform and his status as Token Good Teammate is increasingly called into question. This comes to a head after the two are captured and torturers burn out Shivers' eye. Ultimately, Shivers ends up as a cruel Blood Knight who revels in violence, and betrays Monza, whereas Monza ends up as a hard but fair ruler who spares Shivers because of deep regret of her earlier contempt toward his scruples, which she now embraces.
  • The plotline of the short story "Come Back Gizmo"; after a boy mistreats his dog because the girl next door tells him to, a strange man gives the dog a gizmo that causes the boy to turn into the dog, and vice versa, until eventually it switches their brains as well as their bodies.
  • Older Than Steam: In the first part of the novel, Don Quixote is a Daydream Believer Mad Dreamer and Sancho Panza has Simpleminded Wisdom and represents realism. Both are StaticCharacters. At the second part, Sancho is influenced by Don Quixote and becomes more and more of a Daydream Believer, while at the end, Don Quixote will become Bored with Insanity by Sancho’s influence. They may have been the very first characters in literature to become DynamicCharacters.
  • Harry Potter:
    • As revealed in the finale book, Severus Snape and James Potter. In the beginning, Snape is the neglected, awkward outsider who befriends muggle-born Lily Evans. When they go to school, both he and Lily take a dislike to the wealthy and popular James Potter, albeit for different reasons. Snape hates James because James has a loving family and plenty of talent while Snape has a horrible home life and does not like anyone looking down on him. James hates Snape because Snape is genuinely an asshole and a shady character, though other reasons come into play. However, as the years go by, Snape falls in with a gang of Voldemort supporters and loses Lily's friendship forever when he publicly calls her a slur. The popular boy eventually wises up and matures into someone Lily could actually marry, while Snape grows more and more mean-spirited over the years, and spends his adulthood being antagonistic to those he deems lesser than him.
    • Another example would be Neville Longbottom and Draco Malfoy. In the first book, Neville is a clumsy Butt-Monkey who constantly bungles spells and is bullied by the Slytherins. Malfoy, on the other hand, is the arrogant top dog of the Slytherins who makes Neville's life hell. By the seventh book, Neville develops into a brave and confident leader among the Gryffindors and all the other students who revolted in the Final Battle, even distinguishing himself by decapitating Nagini with the Sword of Gryffindor. Malfoy, meanwhile, becomes a cringing coward whose former followers turn on him and who just barely manages to scrape a Heel–Face Turn to avoid becoming another Death Eater casualty in the Final Battle.
  • In Les Misérables, Cosette starts out as a child slave to the Thenardiers, who abuse her while spoiling their own daughters with expensive clothes and toys. She is then taken into the care of Valjean and nine years later is an educated, well-dressed young lady who enjoys wealth and high social status and eventually becomes a Baroness on marrying Marius, while the Thenardiers lose their inn and become destitute, forcing their daughters to beg and steal on the streets. This is lampshaded by Eponine at one point in the musical.
  • In William Faulkner's Light in August, this happens to Lena Grove and Byron Bunch. Not that any Faulkner book is comprehensible the first ten times you read it, but it's there.
  • In Thomas Hardy's 1886 novel The Mayor of Casterbridge, Michael Henchard is a reasonably successful grain merchant and the mayor of his hometown of Casterbridge, and when the wife and daughter he sold at auction in a moment of Alcohol-Induced Idiocy seek him out after the man who bought them is lost at sea, he is delighted to have them back in his life and re-marries his wife. At the same time, he befriends a young Scotsman, Donald Farfrae, who is well versed in the latest technology of the grain industry and seems to be just the thing Henchard needs to stabilize his business; however, he fires him in a fit of jealous anger over his growing popularity. By the end of the book, Henchard's past follies and short temper have caused him to lose his business, his fortune, his family, and his position as mayor, while Farfrae sets up his own successful grain business (at which he employs Henchard after the latter goes broke) and buys Henchard's house and most of his furniture when they are sold to pay his debts, marries first a woman who came to Casterbridge hoping to marry the now-widowed Henchard, then Henchard's "daughter" (revealed to be the daughter of the man who bought his wife, Henchard's own daughter having died in infancy), and becomes the mayor of Casterbridge.
  • No More Diapers for Ducky!: Ducky knocks on Piggy's door wanting to play, but Piggy is busy sitting on the potty. The book ends with Piggy waiting to play while Ducky sits on the potty.
  • In the Vampire Mountain arc of The Saga of Darren Shan, Darren meets Kurda, who has been elected to become a Vampire Prince. They become friends, until the end of the fifth book, when Darren has been condemned to death for failure to complete a task, and Kurda helps him escape... and Darren finds out that Kurda has betrayed all of the vampires. Darren returns to the mountain and exposes the plot, resulting in Kurda being executed, and the Vampire Princes making Darren a Prince because it's the only way to avoid executing him. It's one of the many places where this series ends up being far deeper than it looks. This is lampshaded by Darren in the manga adaptation - drawn by Takahiro Arai who would later draw a truly stellar manga adaptation of Les Misérables.
  • The Scarlet Letter features an Hourglass Plot between Hester and Dimmesdale on several levels, especially at the end of the novel.
  • Used light-heartedly in the A.A. Milne poem "Twice Times". There are two little bears, a bad one and a good one..."And then quite suddenly (just like Us)/One got Better and the Other got Wuss." Milne then reveals that he's using this as an allegory, since he just realized that his son has finally learned all his times tables, while he's getting so old that he can no longer remember where he put anything.
  • In Warbreaker, the sisters Vivenna and Siri are initially introduced with Vivenna as a well-mannered and seemingly perfect Princess Classic all set to become queen of Hallandren, and Siri as a disobedient Rebellious Princess running away from her responsibilities. Circumstances make it so that Vivenna has to play a Rebellious Princess type role and Siri has to become a Princess Classic, and over the course of the story, Vivenna's flaws and Siri's virtues become apparent. Ultimately, Vivenna becomes an Action Girl, running from her responsibilities while she figures out who she is, while Siri is all set to become queen of Hallandren, for good this time.

  • Angel: Two examples, both related to the rogue slayer Faith:
    • Her two-episode arc in Season 1 first has Angel going after Faith, and Wesley trying to hold him back, insisting she can be rehabilitated; then in the next episode, after Wesley gets kidnapped and tortured by Faith and Angel realizes her true motives, they switch roles. The arc goes even further back, to Buffy the Vampire Slayer Season 3, in which Angel's attempt to rehabilitate Faith is interrupted by Wesley getting her arrested by the Council, meaning they have switched roles twice on the subject.
    • Her return in Season 4 is a double example. She switches her role in the Good versus Evil battle with the now soulless Angel(us), as well as her outlook on life with the now cold and jaded Wesley.
  • The Narn and the Centauri in Babylon 5 are caught in an apparently endless cycle of invasion, occupation, liberation and revenge. G'Kar starts out as the arrogant jerk seeking power and advancement while Londo is humbled and accepting of his position in life and the lack of any real power. A couple seasons later G'Kar is humbled and powerless while Londo has become one of the most powerful men in the Centauri Empire with the arrogance to match it. By the end of the series they start flipping again though they lose their arrogance for good.
  • BIA: Carmín and Mara start out as the Alpha Bitch and her quiet, invisible, often ignored assistant. Carmín undergoes a Heel–Face Turn and ends up joining El Fundom, and Mara becomes the new Alpha Bitch.

  • Daredevil (2015): In a minor example, Matt and Karen's first two kisses in Season 2 fall into this. At the end of "Penny and Dime," Karen walks Matt home to his apartment in the rain, Matt stops her, and they share a kiss. In "Kinbaku", which takes place over the events of the next day, they end their first date with Matt walking Karen back to her apartment, and then they share a makeout session on her front steps.
  • On Degrassi Junior High and Degrassi High, neurotic, insecure Melanie is best friends with the insensitive Kathleen. Melanie gains confidence while Kathleen loses hers, and Melanie becomes just as insensitive as Kathleen was when they started. Their problems escalate as they get older, so Kathleen is insensitive to Melanie worrying about her body, while Melanie is insensitive to Kathleen becoming an anorexic abuse victim.
    • The fifth season of Degrassi: The Next Generation has Emma swapping moral positions with her entire circle of friends and family. They screw up their lives one by one, Emma redeems them all — and then she snaps under the pressure, becoming worse than any of them ever were. The climax is them trying to reason with her, as Emma threatens them and says they have no moral right to criticize her. ("You take advantage of drunk girls. You are the drunk girl...")
    • Joey and Wheels as well. At the beginning of Degrassi Junior High, Joey was an irresponsible jokester as well as a bit of a bully while Wheels was his nicer and more sensible best friend. Near the end of Degrassi High, Wheels was a Jerkass whose various misdeeds involved stealing money and lying to his grandma/guardian. Meanwhile, a matured Joey disapproved of his actions and tried to help him.
  • Friends: Rachel and Monica. In the series' back story, Rachel was a Rich Bitch and engaged to marry an equally wealthy guy, while Monica was a Formerly Fat poorly-paid assistant chef who thought she'd die alone. During the series Rachel breaks off her engagement, works as a waitress and has a lot of disastrous boyfriends, while Monica works her way up the chef ranks — despite a rough, unemployed patch in the middle — and builds a stable, fulfilling relationship. By Season 9, Rachel is a single mother, working a good but not exceptional fashion job and has a series of failed relationships (and a marriage) under her belt. Monica is an Executive Chef at one of New York's most prestigious restaurants and is Happily Married to her best friend. Things do improve for Rachel by the end of the series, but the contrast is still there.
  • Game of Thrones: Tyrion Lannister, the man described by his own father as the "least of the Lannisters", ends up becoming the most universally liked of the family by the time of Season 7, the only one liked by the rival factions of House Targaryen and House Stark, and acts in the series finale in the Dragonpit Summit as the linchpin of Westeros.
  • Gilmore Girls played this with Rory and Jess. In early seasons, Rory is a hardworking, honours student, bound for an Ivy League, aiming to pursue journalism and the golden child of her family, while Jess is a high school drop out with zero life ambitions, his mom kicked him out and he's at odds with his uncle. Come Season 6, Rory has dropped out of college, abandoned her career dreams, and is estranged from her mother, while Jess is a successful author, runs a publishing house with friends, and is closer to his uncle than ever before. Luckily though, Jess's transformation is exactly what Rory needs to get her life together.

  • Our Miss Brooks: The penultimate episode of the television series, "Principal For A Day", has Miss Brooks appointed principal and Mr. Conklin become a History (not English) teacher. Because Status Quo Is God, their respective positions are restored at the end. Neither seem to learn much from the episode. Miss Brooks enjoys herself thoroughly, and other than adding feminine touches to her office and spending some quality time with Mr. Boynton doesn't abuse her power. Mr. Conklin's temporary humility, and appreciativeness to Miss Brooks' giving him the teaching position, is cast off as soon as he becomes principal again. It helps that Mr. Conklin is a pompous Jerk with a Heart of Gold than an outright villain.
  • Outnumbered: Jake and Ben have shades of this. At the beginning of the series, Jake is the serious, geeky older brother who is much closer to his parents, while Ben is the rebellious, outgoing son.

Meanwhile, Elaine, for whom things had been going great, suddenly finds herself unemployed, homeless, and in a romantic slump, realizing to her dismay that "I've become George!". Jerry lampshades the trope with his subplot of how he always manages to break even.
  • Shadow and Bone: Nina and Matthias's subplot. They meet aboard a ship where Matthias's people have taken Nina captive; Nina is justifiably spiteful towards him. When the ship capsizes in a storm the two are thrown together by a need to survive and develop feelings for each other. However, at the end, Nina has claimed that Matthias is a slaver to stop him from being executed by Grisha, and so the two end up on a ship bound for Ketterdam. This time however, it is Nina on the other side of the bars, and Matthias reacts with hatred and anger when he sees her, believing that none of their interactions were real.
  • Smallville:
    • Lex and Lionel Luthor. At the beginning of the series, Lex was Clark's friend and ally and Lionel was the Magnificent Bastard. Overtime, Lex begins a descent as Lionel redeems himself.
    • In the early days, Chloe is One of the Boys who ended up tangled with the Luthors, at one point allying with Lionel, prying in Clark's personal life, threatening his secret, and Lana is the pretty girl Clark is crazy over. In the middle seasons however, Chloe learns Clark's secret and becomes a supportive sidekick, gets as far away as the Luthors as possible, Clark subtly demonstrates possible romantic feelings towards her, and her femininity becomes more pronounced (just look at her hairstyle change); Lana marries Lex and becomes something of a Dark Action Girl, and starts poking into Clark's secret, not to mention starting Isis.
  • Star Trek: Voyager, "Equinox": The Voyager crew comes across their Evil Counterpart: the lost ship Equinox, whose crew are murdering and enslaving their way across the Delta Quadrant.

  • Supernatural:
    • At the start of the series Sam has almost managed to escape his hunter upbringing in favour of a normal life, when he's dragged back to the hunt by Dean, who idolises their father and argues that a normal life is for chumps. Over the course of the first five seasons (which is to say, the arc of the show as originally plotted), Sam gets increasingly militant in the fight against evil, while Dean gets increasingly heartsick and tired of the whole thing. The Series Fauxnale at the end of Season 5 sees Sam is giving up not just his life but his eternal afterlife to put Lucifer back in his cage and averting the apocalypse, and Dean retiring to a peaceful life with his girlfriend and her son. Since the series didn't end there, neither of those things lasted for very long, and by season eight the brothers had arguably switched places again, but that's another story.
  • An episode of The Twilight Zone (1959), "Of Late I Think of Cliffordville," has the janitor for a large corporation talking with the CEO of the corporation about how he's just gotten a watch for his 40th year with the company, along with a few words about what it's like at the top versus the bottom. One botched trip to the past and several deals with the devil later, not only is the janitor now the CEO and the CEO the janitor, but each now has the personality of the other as well, and the watch gets a mention too.
  • Why Women Kill has this in spades with the characters of Rita and Alma. At the start of season 2, Rita is an immoral Villain With Bad Publicity who has good looks, money and shallow but numerous friendships with rich socialites like herself. She does wish her rich, emotionally abusive husband would die so she could move with her gigolo, whom she worries may not truly love her. Meanwhile, Alma is a dutiful and frumpy middle-class housewife who lives a life of boring drudgery but her husband and daughter love her deeply and she quickly makes a real friend when she tries to get out. By episode 9, Rita is The Scapegoat for the murder of Rita's husband and revealed her affair, meaning she's ostarcised by all and she loses her money, status, FalseFriends and fancy clothes. However, Rita has changed worldview and both her gigolo and her maid/cousin have proven that they actually love her, which she now values and wants to reciprocate. Even if that realisation might have come to late and she may lose them both, she at least has solid moral basis on which to rebuild her life. Meanwhile, Alma has gotten everything Rita once had. At the cost of her Only Friend, her husband and now either her daughter or her daughter's marriage. And the cops are onto her.

  • This is a big part of the plot of Shaw's The Devil's Disciple. Richard Dudgeon is introduced as a n'er-do-well who has his opposite in the Rev. Anthony Andersen, a philanthropic clergyman. The plot is set in motion when British soldiers come to arrest Andersen for treason and Dudgeon takes his place. Ultimately, Dudgeon's nobility and Andersen's weakness are revealed, and at the end of the story, Dudgeon is established as heroic (and much less seedy than he initially appeared), and Andersen has renounced religion and become a Blood Knight revolutionary. The trope is exaggerated, as Andersen asserts that since he has taken Dudgeon's place, Dudgeon must become a clergyman and take-up with Anderson's wife.
  • The second and third songs of Hamilton emphasize the contrasting nature of Alexander Hamilton and Aaron Burr. "Aaron Burr, Sir" makes clear that Burr will not choose a side until he's certain that it's the right one (something that is codified in "Wait For It", "Non-Stop", and "The Room Where It Happens"), while "My Shot" shows that Hamilton "will not throw away [his] shot", is always one of the first to support something he thinks is right, and wears his emotions and beliefs on his sleeve. Over the show, Burr and Hamilton begin to learn from each other (they even say as much in "The Room Where It Happens" for Hamilton and "The Election of 1800" for Burr), and in the final duel, Burr takes the rash, impulsive action of shooting Hamilton, while Hamilton decides to take his time to consider what to do and eventually chooses the safe option of firing at the sky, not Burr.
  • Macbeth: Initially, Macbeth shows more scruples/hesitancy to kill Duncan than does his wife, and she pushes him into doing it. Afterward, however, while Lady Macbeth goes increasingly mad from guilt, Macbeth's reaction to guilt is to seemingly lose all emotion and scruple and he far surpass his wife in villainy.
  • The play Pacific Overtures has two friends, one a samurai and the other a peasant with knowledge of the West, who wind up exchanging places. The samurai is made an ambassador of sorts with the foreign powers as Japan is forcibly opened to trade, and he becomes increasingly westernized in his dress and actions. Meanwhile the peasant, angry at the way Western powers are exploiting Japan, becomes a hardcore anti-West reactionary after being promoted to the samurai class. Tragedy ensues.
  • In Harold Pinter's "A Slight Ache" a middle-class couple invite a tramp into their home; by the end of the play, the husband and the tramp have exchanged places.
  • Alma Winemiller and John Buchanan Jr., two main characters of Summer and Smoke by Tennessee Williams, swap their views on sexual freedom.

At the end of the play he's engaged to Alma's young pupil and she's about to go to the seedy casino with a traveling salesman that she just met.
  • In Shakespeare's Twelfth Night, Antonio saved Sebastian's life after a horrific storm, when they were both mired in a strange country. Antonio grew very close to Sebastian, and even got into a duel in Sebastian's defense. When Antonio was placed under arrest by Orsino, his old rival, he expected that Sebastian would help him out — only for Sebastian to act like he's never met Antonio before. Antonio is heartbroken — but fortunately he had really met Sebastian's Half Identical Twin, and the real Sebastian is perfectly happy to help Antonio once he finds him again.

  • Once you've made the Cosmic Horror Reveal in Bloodborne, the Great Ones become these alien, unknowable things that barely even seem to register the fact that they're literally crawling on top of the city of Yharnam. Even the occasional one that pays you enough attention to try to pick you up seem to regard you with roughly the same significance as you would a bug. As you progress, however, you learn that the Great Ones are generally sympathetic in spirit: Rom tries to protect mankind from Things Man Was Not Meant to Know that would make them Go Mad from the Revelation; Ebrietas tries to teach mankind about the secrets of the cosmos in a way that won't ruin them; the Wet Nurse attempts to help humanity transcend and become godlike in their own right, which would also fulfill the Great Ones' desire to sire descendants, and the Brain of Mensis just wants to be left alone. Mankind, in return, kill Rom precisely because they wish to discover what secrets she's keeping from them, they become Mad Scientists and Church Militant Sinister Ministers who abuse Ebrietas' gifts in order to oppress each other and transcend their own humanity, they launch a hunt to kill the Wet Nurse's protégé, and capture, experiment upon, enslave and finally butcher the Brain of Mensis. The real turning point in the story is arguably when Amygdala, who tries to play her traditional role completely straight, ends up with a lethal case of Cthulhu Breaking Her Arm Punching Out A Human, and it culminates with the Moon Presence, who's been trying to free humanity of the Great Ones' influence by exterminating its own kind, finding itself on the recieving end of the extermination once mankind has discovered a way to usurp the Great Ones by becoming Great Ones themselves. That's right, in this story, humans end up being, quite literally, Cthulhu to Cthulhu; we're a race that exploit, betray and exterminate a race of Lovecraftian gods for no greater or knowable reason than simply because we can.
  • Between Donkey Kong and Donkey Kong Jr, Mario and Donkey Kong switch roles, the antagonist capturing somebody the protagonist cares about and holding them hostage.

  • The Legend of Zelda: The Wind Waker features one of these; a rich man and a very poor man both have their daughters kidnapped, and the circumstances surrounding their return swaps them over. When you first arrive on Windfall Island, Mila's father is a snooty collector of expensive vases who resides in an opulent mansion, while Maggie's father is a timid beggar who pleads for anyone passing by to rescue his daughter. When the pirates return the girls, they extort Mila's father out of his fortune, leaving the newly-reunited family destitute and living on the street; the experience humbles Mila's father and teaches him that there are more important things than money. Meanwhile, Maggie's father manages to make a killing off the rare Skull Necklaces that Maggie brought back with her, allowing them to move into the newly-vacated mansion; in the process, he becomes an arrogant snob who turns his nose up at everyone else and throws temper tantrums when the postman tries to deliver mail to his house.

However, Papyrus proves unable to go through with it and ends up befriending the player character, or allowing himself to be killed should the player choose to. By contrast, Sans later ends up confessing that he would have killed the player character on sight had he not previously promised Toriel to not kill them, and proves to be That One Boss should the player choose to go with the Genocide/No Mercy route.

  • The arc of Band vs. Band where they get sick roughly follows this structure: when confined to her room with a broken ankle, Honey Hart slowly finds her plucky persona slipping, whereas gothic hellraiser Turperntine finds she can't raise hell half as well when she's lost her voice. They both come out of it with newfound respect for each other.

  • This happens in Avatar: The Last Airbender episode aptly named "Crossroads of Destiny" between Aang and Zuko. Aang is The Chosen One who up to that point had successfully fought off The Empire, while Zuko was a banished, disgraced prince abandoned by his father, the Evil Overlord of said empire, after repeatedly failing to capture Aang. The episode finally sees Aang defeated with Zuko's help, and the following episode brings out that Zuko is now accepted as a prince again in his home country with the approval of his father and famed for killing The Hero, while Aang is thought to be dead after having failed to defend the capital of the one country that could fight against The Empire.
    Aang: I need my honor back.
    • This happens to Zuko and Azula as well. Azula had always been in her father's favor; a remorseless, sadistic killing machine, expert chessmaster, and flawless fire-bender while Zuko was The Unfavorite Noble Demon whose conscience made him too much of an outcast in the family. Zuko is eventually exiled from the Fire Nation and left longing for his father's acceptance, turning into a Ineffectual Sympathetic Villain after his many failures to catch Aang. Zuko's character development helps him get over his torment over being neglected by his father, and an expert in fire-bending, and with Aang's help he winds up taking the throne to end the war and become a celebrated leader. Azula, meanwhile, is brushed off by her father and tossed aside when he begins his ploy for global conquest, and after being confronted by her deeply repressed conscience, manifesting as a hallucination of her mother, Azula regresses into a pitiful, insane child. She's eventually confined to a madhouse, tormented by her deeply delusional belief that her mother never loved her as much as Zuko. Even when her mother later apologizes for abandoning her children, Azula still refuses to acknowledge her mother's love for her.
    • Aang and Zuko are this to the previous Avatar (and one of Zuko's great grandfathers), Roku, and the Fire Lord (another one of Zuko's great grandfathers), Sozin, who started the 100 year war and perpetrated the Airbender genocide. As boys Roku and Sozin were best friends but began drifting apart when Roku got back home from a decade spent mastering the other elements and Sozin became the Fire Lord. At Roku's wedding reception, Sozin (the best man) pulled him aside and wanted him to be his partner in imperialism. Roku told him no and to never bring it up ever again. Sozin started going behind his back and when Roku found out, he kicked Sozin's ass but told him he'd spare him on account of their past friendship. From that point on they were enemies. It culminated with Sozin leaving Roku to the mercy of an erupting volcano because with Roku out of the way, he'd be able to Take Over the World. He committed the genocide about twelve years later. Aang and Zuko started off as enemies or as Uncle Iroh puts it, "their relationship started off a little rocky" who grew to be best friends who together led the world into the more peaceful era of The Legend of Korra.
  • Batman: The Animated Series: "Joker's Favor" begins with the Joker threatening to kill Charlie Collins after Charlie yelled at him for cutting him off in traffic, and ends with Charlie threatening the Joker with an ignominious death "blown to bits in an alley alongside a miserable little nobody". Subverted in that Charlie is perfectly content to prank the Joker, leaving him terrified and gibbering in Batman's custody, while the satisfied Everyman himself goes home to a possible meatloaf dinner and learns to appreciate his humdrum life.
  • Snake Eyes and Storm Shadow share one in G.I. Joe: Renegades. After Snake Eyes is accused of poisoning Hard Master, Snake Eyes is forced to flee his family with the Arashikage and life as a ronin which sets him on the path of joining the Joes. Meanwhile, Storm Shadow becomes de facto leader of the clan with his uncle's death. Towards the end of the series, he realizes that he was indirectly responsible for Hard Master's death and exiles himself from the clan, while Snake Eyes is absolved and moves on with his new adopted family.
  • On Gargoyles, the three-part "Hunter's Moon" arc has three siblings acting as the current Hunters. Jason, the oldest and leader, hates gargoyles the most; the youngest, Jon, was willing to believe gargoyles other than Demona might be innocent. When it seems like the gargoyles are responsible for Jason's death, however, Jon snaps and turns fully against them; Jason, meanwhile, actually survives and realizes the gargoyles are good. When Jason tried to defend them against Jon, the latter accidentally shoots and paralyzes the former, which he quickly blames on the gargoyles (in a "Not So Different" Remark moment with Demona).
    Jon: What have I—what have they done to you?!
  • I Am Weasel combines this with "Freaky Friday" Flip. "I Architect" sees Weasel and Baboon's brains switched after an accident. Baboon becomes a renowned hero, while Weasel acts like a total idiot and is "gifted" a mandatory retirement.
  • The Looney Tunes short "Tree for Two" begins with Bully Bulldog Spike being fawned over by smaller dog Chester. The two encounter Sylvester and chase him, cornering him in an alley. Unfortunately, an escaped panther is hiding there, and whenever Spike tries to get Sylvester, the panther attacks him. Neither Spike nor Chester are aware of the panther, so Spike thinks it was Sylvester who beat him, while Chester, who is able to beat Sylvester easily, doesn't understand why his hero can be defeated by a puny cat. By the end of the cartoon their roles have been reversed, with Chester as the tough guy and Spike as the adulating fanboy.
    • In an early Daffy Duck cartoon, "Daffy Duck in Hollywood," Daffy plays The Prankster tormenting the snobby director. By the end of the cartoon, Daffy is the snobby director while the snobby director is The Prankster.
  • In the Muppet Babies (1984) episode "Who's Afraid of the Big Bad Dark", Beeker, having seen a slime monster movie a few nights ago, is scared of the dark and can't sleep (keeping Bunsen awake in the process), so Kermit and the others help show him there's nothing about the dark that's scary. In the end, Beeker conquers his fear of the slime monster and is able to sleep that night, however, Kermit, after all the encounters with the monster throughout the episode, is unable to.
  • The plot of Princess Gwenevere and the Jewel Riders episode "Dreamfields". Kale and Gwen are hit with some magic that causes them to hallucinate they've swapped places. It's enough to almost get Kale to Heel–Face Turn...but not quite.
  • In The Ren & Stimpy Show episode "Nurse Stimpy", Ren has gotten sick and Stimpy takes it upon himself to nurse him back to health. After enduring Stimpy's well-meaning but humiliating treatments throughout the entire episode, Ren is healthy again, but Stimpy has spent so much time watching over Ren that now he is sick, and Ren is all too happy to return the favor Stimpy gave him.
  • Samurai Jack; the episode "Jack Learns to Jump Good" starts with Jack rushing for a time portal which he believes will lead to his goal, only for Aku to appear out of nowhere, grab it, and mock the hero as he futilely tries to leap for it. End of the episode, the same thing happens, but now that Jack can "jump good", he interrupts Aku's gloating by doing so with his sword drawn straight for Aku's face, to the villain's utter horror.
  • Steven Universe:
    • The first time we see Ruby and Sapphire break apart from Garnet, Ruby was livid and Sapphire was calm when dealing with Pearl lying to them about fusion, because Sapphire was able to see the outcome with her future vision that time. However, after they discover Rose was Pink Diamond the whole time, they break apart again, and Sapphire, unlike Ruby, is absolutely livid that "Rose" lied to them for millennia, to the point where she runs away in tears.
    • In "The Answer", Ruby and Sapphire first fused because Ruby refused to accept that Sapphire's fate of being poofed, which she had foreseen, was inevitable. In the movie, after they've both been rejuvenated, they re-fuse when Sapphire takes action to save Ruby, who had accepted being shattered by a falling anvil because at least she got to spend time with Sapphire, as Sapphire refuses to let the future she predicted come to pass. It also demonstrates they retain some traces of their memories.
    • Since the beginning of the series, Steven was the one who helped everyone during their moment of crisis and helped them to change their ways for the better. In the Future episode, "I Am My Monster", however, everyone returns the favor by saving Steven from his corrupted form.
  • In the Wander over Yonder episode "The Day", Wander is asleep and Sylvia has to find a way to escape Lord Hater and his Mooks while also keeping Wander asleep. This causes Sylvia to feel tired and needing some much needed rest, while Wander has a lot of energy after being asleep, leading into the events of "The Night", where Sylvia is asleep and Wander has to make sure she stays asleep, first from mundane things such as crickets to three of Lord Hater's Mooks trying to capture the two (who are also kind enough to keep Sylvia asleep). The first scene of each segment also serves as the last scene of the opposite.
