Doppelgänger Replacement Love Interest
Close enough.

"Earth. After the War. Three years have passed since I saw your face. I wonder if I come to you, at night, in dreams; in the day, as memories.
"Do I haunt your hours, the way you haunted mine? And I wonder if you see me, when you look at her?
"If we have souls, they are made of the love we share; undimmed by time, unbound by death.
"For three years I searched for the house he built. I knew it had to be out there. Because I know him. I am him. I am Jack Harper, and I'm home. "
— Final lines of Oblivion

So the protagonist is forced to part with a love interest for fantastic (supernatural/fantasy/science fiction) reasons. But it's okay! Because at the end of the story they meet a mundane person who happens to look exactly like the person they lost. Usually it's never explained why this person looks exactly the same, but it's a quick way to turn a bittersweet ending into a happy ending.

Usually, the new love interest has been relationship-free for some time, or just got out of a long term relationship.

If time travel is involved, the love interest in the present is often an identical grandson or grandfather, which also makes for some incestuous implications if you assume they get married and have babies.

Not to be confused with Replacement Goldfish. Note that this trope only applies when the new love interest appears by devices not possible in the world as we know it, such as magic, parallel universes, time travel, or cloning. If there's a mundane explanation (or none) for the Suspiciously Similar Substitute, that's plain old Replacement Love Interest. See also Doppelgänger, obviously.

See Settle for Sibling for when the old and new love interests are twin brother/sisters.

Due to the nature of this trope and its close association with Death Tropes, spoilers are likely.

    Anime & Manga 
  • In Gantz, this is subverted with Kurono and Kishimoto. When Kishimoto died during a mission, Kurono thought to try and pursue her original that was still living a normal life. However, she ends up thinking Kurono is a nutty stalker and runs away from him.
    • However, this trope is followed in relation to Kato and Kishimoto. It's implied that Kato has finally decided to get together with Kishimoto's original, and she seems to have taken a liking to him.
    • And the manga does this to a T with Reika's very own Kurono, who she resurrects with this trope in mind.
  • In Threads Of Time, this is what happens to Moon-Bin at the end. Although he isn't able to end up with Atan Hadas from the past, when he goes back into present time, it's implied that he ends up with a girl (that always liked him) who is identical to Atan Hadas.
  • InuYasha plays with this trope in the situation between Inuyasha, Kikyo, and Kagome. After Kikyo's death, plenty of characters who knew Kikyo are struck by the similarity between Kikyo and Kagome (justified by the fact that Kagome is Kikyo's reincarnation), resulting in Kagome angsting over being compared to Kikyo. Inuyasha himself was initially repulsed by Kagome because her scent was so similar to Kikyo, something he got over when he realised their scents weren't the same. He didn't actually notice the physical resemblence between the two until he caught Kagome sleeping one time and had the chance to really study her face to see what everyone else was going on about; for him it didn't really factor in to how he handled Kagome. As a result, the trope is played with because while the resemblence is there, it's not the driving force behind their relationship or the reason Inuyasha became attracted to Kagome. The differences between Kagome and Kikyo are, in fact, so stark, that Kikyo and Kagome have trouble understanding each other and Inuyasha never has any trouble keeping the two women straight in his head because their personalities and motivations are very different.
  • Toyed with in MÄR with Koyuki being Ginta's love interest from the real world, and he ends up having fallen for Snow, her exact counterpart in the fantasy world. In the end, he decides to return to the real world and, in the anime, starts dating Koyuki, who Snow's spirit has joined with.
  • Played with in the second half of Fushigi Yuugi. After Miaka encounters a man who looks identical to Tamahome, named Taka, in her own world, it's said that he's Tamahome's reincarnation. After Taka suffers from some Cloning Blues, Suzaku admits that Taka Sukunami is not Tamahome's reincarnation, but a regular man who was meant to unite with Tamahome's memories.
  • Ultimately averted in Project ARMS. Almost immediately after the apparent death of Katsumi, a girl named Kei is introduced. She looks exactly like Katsumi (to the point where it's later revealed that she was Katsumi's clone and Ryo is obvious struck by this resemblance. But then Ryo and Kei only ever are friends, while Hayato becomes her love interest. Katsumi, meanwhile, turns out to be alive, and Ryo spends the series trying to rescue her.
  • In Mahou Sensei Negima! Eva from the future states that one of her goals is to find an "extra Nagi", after she gets a dimension jumping machine from Chao.
  • In the ending of Future Diary, Yuno dies, but Yukiteru eventually gets together with her 3rd World counterpart, who was given her memories. As a bonus, since her counterpart had a happier life, she is not a Yandere.

    Comic Books 
  • In the X-Men comics, after Jean Grey "died" in The Dark Phoenix Saga, her boyfriend, Scott Summers, met and married Maddie Pryor, a girl who looked just like her and turned out to be a clone of Jean created by an enemy. Of course, it's not a straight example because Jean wasn't really dead and later came back to marry Scott and the original script would've had Maddie be someone who looked like Jean. That's it. No reincarnation, no clone, just someone who happens to look like her. Unfortunately, an anniversary was rolling around, and Marvel wanted something big. So, they retconned Maddie into a clone for the sake of a story.
  • In Countdown to Final Crisis The Atom Ray Palmer ended up in a parallel universe where his counterpart had just died. He tried to make a new life for himself there and got together with the counterpart of his insane ex-wife Jean Loring. Amazingly enough, things were actually going pretty well — but since this is Countdown, which was described on this wiki as DC's love letter to Kill 'em All, it didn't last.
  • In RASL, the protagonist's girlfriend is killed and then he finds himself in a parallel universe where she's still alive — and so is his longer-dead wife. This being RASL, this only makes his troubles more complicated.
  • When Earth-1 was destroyed the original Black Canary's husband was killed. When she was transported to a new Earth she met their version of him and instantly began flirting with him.
  • In Injustice: Gods Among Us, Black Canary was in a relationship with Green Arrow, but he died in their home universe. At the end of the second year she gets brought Back from the Dead and meets an alternate universe Arrow, while Doctor Fate explains that this Arrow lost his own Canary five years ago. While Fate says knows the two have never met and that he cannot guarantee them happiness, he can give them each other. The scene ends with Arrow calling her "Pretty Bird", the original's pet name for her.

    Fan Fiction 
  • At the end of Code Geass: Mao of the Deliverance, C.C. takes Mao to C's World while he is unconscious and leaves him there with the mental version of herself so he can be happy. Mao's reaction, however, is a subversion as he, while grateful for the gesture, is ultimately NOT satisfied and determined to get back.
  • In the infamous My Immortal, when Draco is kidnapped by Voldemort, Ebony Dark'ness Dementia Raven Way mentions how Vampire looks exactly like Draco... before screwing him in front of the class. Which is even more ridiculous when you remember that "Vampire" is supposed to be Harry and he doesn't look like Draco.

  • In Susie Q, Zach falls for Susie, a ghost who needs to settle her family's unresolved affairs before moving on to the afterlife. With the help of Zach, she succeeds and moves on to the afterlife and is reunited with grandfather and boyfriend. The next day at school, Zach runs into a new student named Maggie (played by the same actress). It's strongly implied that she's Susie's reincarnation, sans Susie's memories. The situation prompts Zack to give a baffled glance to the camera
  • Xanadu has the protagonist parting with a muse played by Olivia Newton John, only to meet an identical waitress at the end. Or the waitress actually is said muse, trying for a version of the relationship her family can at least pretend they don't know about. Some of her parents' remarks leave it a bit ambiguous.
  • A Connecticut Yankee In King Arthur's Court (1949). Bing Crosby's character meets and falls in love with Alisande La Carteloise ("Sandy") in King Arthur's time. When he returns to the present, he meets a woman who looks just like her.
  • Likewise, Black Knight has Martin Lawrence meeting a modern ringer for the love interest he left behind in the past. Nicky also has a scar on her neck at the exact same spot where Percival held a sword to Victoria's throat.
  • Played With in A Kid in King Arthur's Court: Calvin falls for Princess Katey in the past, and back in his time her doppelganger seems to recognize him, and there's also a doppelganger of her father King Arthur. The implication seems to be that they time traveled with him, though the novelization plays this trope straight with Katey being a lookalike with the same name.
  • Some onscreen adaptions of The Nutcracker end like this, with toymaker's nephew looking exactly like the eponymous prince (Note, in the original story they are actually the same person.)
  • In The Forbidden Kingdom, the protagonist's love interest dies in her attempt to assassinate the villain, but in the ending, he meets an identical girl in the present.
  • Meet Joe Black seriously inverts this trope. At the very beginning of the movie, Death takes on the aspect of a man who gets hit by a truck just after the female lead falls madly in love with him. Death then proceeds to fall in love with her, and at the end of the movie when he must leave to get back to work, he resurrects the real Love Interest to take his place.
  • Mirrormask: Helena hooks up with Valentine's human counterpart at the end. Although Helena and Valentine himself didn't flirt, not counting her telling her mother that He Is Not My Boyfriend.
  • In the film The One, Jet Li fights his Evil Twin from an alternate dimension. Evil Jet kills Good Jet's wife, frames him, and tries to kill him to become a god. After much chop-sockey, good Jet Li ends up in a version of Los Angeles where the original copy of him has long since been killed off and meets a version of his former wife exactly as he did in his world.
    • This was the plan by Jason Statham's character, who knew that sending him back to his own universe would result in him being put away for his wife's murder.
  • Subverted at the end of The Purple Rose of Cairo.
  • Sort of used in Dark City — Emma Murdoch gets all her memories erased and she becomes Anna, and John Murdoch decides to start over with her. Justified, since their relationship beforehand was fake—Emma's memories of the marriage were no more real than Anna's past, and John had already lost his fake memories. So this replacement relationship is more real than the original one.
  • Given a dark twist in Vertigo. Scottie, despondent over the death of Madeleine, finds a woman named Judy who looks almost exactly like her. The two begin dating, but Scottie starts pressuring Judy to dress exactly like Madeleine. However, what he doesn't know is that Judy actually IS Madeleine, who faked her death but now is struck with a terrible case of Loves My Alter Ego.

When the owner's young daughter has grown, she subtly reveals that she has feelings for Andrew. Having only begun his journey to understand what it means to be human, Andrew has no idea what she means and suggests that she marry her fiancé. She does so. Years later, he is freed by his owner and leaves to find others like him. In the process, he meets an inventor who changes Andrew's appearance to that of a human (his organs are still artificial). He comes back to his former owner's home and kisses the woman he assumes to be the daughter. She freaks out, and it's revealed that many years have passed, and the woman he kissed is her grown-up granddaughter (played by the same actress). And yes, they end up together.
  • Jack 52 in Oblivion (2013). He's the one who said this trope's quote.

  • In Captain America (1990), Steve's love interest from the 1940s waited 15 years after he disappeared to marry and have a daughter (played by the same actress). Steve and the daughter are a couple by the end of the film.
  • The whole plot of The Life and Death of Colonel Blimp turns on this, although the main character never really realizes it.
  • Calvin loses his fictional love interest in Ruby Sparks, but finds an identical real-life counterpart at the end, played by the same actress with shorter hair.

  • In Andrew M. Greeley's Angel Fire, Sean Desmond meets an Irish woman who is a dead ringer for Gabriella, the angel who has shepherded him through the entire book, after she leaves for good. It's implied that Gabriella knew of this coming meeting and used the woman's appearance in order to prime Sean for a relationship with her.
  • In Germline, the main character fall in love with a Genetic in the beginning who kills herself, but then later he meets a clone of her that he falls in love with.
  • In Heir Apparent, the protagonist is trapped in a virtual reality game and ends up developing a bit of a crush on one of the characters.

Luckily he looks just like the game's Teen Genius creator, who shows up to apologize to the heroine personally and seems flattered that she liked the character based on him...
  • In Stephenie Meyer's The Host, one human has his girlfriend taken over by a Soul. The free humans then remove the Soul, but the girlfriend is brain-dead due to the possession by this point—so they just stick the Soul back in the body.

  • In the Last Herald-Mage trilogy of the Heralds of Valdemar series, The Hero Vanyel loses his first Love Interest, Tylendel, in a truly epic tragedy that starts him on the path to becoming the most powerful Herald-Mage in the history of the kingdom. Seventeen years later, he finds a new love interest, Stefan, who is physically dissimilar, but still bears an uncanny psychic resemblance to Tylendel, up to and including forming a lifebond with Van. It turns out that 'Lendel was reincarnated as Stefan, though most of the main characters are ignorant of this until close to the end of the story.
  • John Perry from Old Man's War is very upset by his wife's death. Near the end of the book he meets a special forces soldier who has a body cloned from his his wife's DNA, who looks exactly like her. They end up together.
  • Disturbingly handled in the Scorpion Shards trilogy by Neal Shusterman. The titular "Shards," pieces of a Starfish Character, can only truly love each other. Dillon, the leader of the group, attempts to start a relationship with an outsider, but is haunted by memories of a female Shard who died in the first book. The solution is best summed up by the tropes involved: Death Is Cheap for the female Shard, Death of the Hypotenuse combined with Deader Than Dead and Heroic Sacrifice for the outsider, and Freaky Friday plus That (Wo)man Is Dead just to up the weirdness.
  • Inverted in Solaris—a doppelganger is created to remind the protagonist of a love interest he failed to save, and he eventually falls in love with her. This is not a case of Replacement Goldfish, as he remains well aware that the copy isn't the same person as the original. It still ends rather badly, though.
  • Subverted in Harry Harrison's To the Stars trilogy. Starworld (the third in the trilogy) has the protagonist sent to Israel to meet a contact, and he at first is shocked to see Sarah, his dead love who was killed in the first book.

They end up having sex, but it turns out they're both married (he got married in book two) and have no intention of leaving their spouses.

After escaping the city, however, a fulga (a shapeshifting elemental being) finds him and assumes Marianna's form to comfort him and help him recuperate after the Trauma Conga Line he just suffered, without adding any more trauma to it. The Magnificent Bastard Marcel Valme actually sees through her disguise and confronts her, but after confirming that she has no ulterior motive for Robert, he lets her carry on, since he wants Robert up and running ASAP.

  • The Outer Limits (1995):
    • Subverted in "Second Soul". One man's wife dies and donates her body to an alien race (they can occupy and revive recently dead bodies, and need to do so to live). He meets the recipient, and finds out that they do sometimes inherit random memories from their hosts, but she does not fall in love with him, becomes bothered by him following her around and eventually gets a restraining order against him. It's even hinted that the process is set up to prevent the aliens from being close to family members of their hosts, presumably to prevent this from becoming a regular occurrence.
    "If I look like her, if I sound like her, I might be her? The answer is no."
    • In "In Another Life", a man mourning the death of his wife gets sent to a parallel universe. He quickly tries to find the alternate version of her, only to discover she already has a boyfriend.

  • Avoided in Chou Ninja Tai Inazuma Spark, the samurai from the Edo period lost his sister in an alien attack, then at the end of the story goes to live in the future, where he finds out that someone who looks just like his sister is an actress. At first he's elated to be "reunited" with his dead sister but goes running off screaming when he finds out that she's The Ditz.

She was the grandaughter of the woman he had been involved with. As they grow closer he admits that at first he was drawn to her because of the resemblance but later it was all about her.
  • Doctor Who:
    • Jackie Tyler became a widow while her daughter was a baby. In a parallel universe, Pete Tyler lost his wife during the Cybermen incident. When the former ended up in the universe of the latter, the two paired up, meaning that each was the other's Doppelgänger Replacement Love Interest.

He gives her his blessing while thinking this. When he discovers that her boyfriend is actually a charismatic former soldier who looks and acts absolutely nothing like he ever did - and Clara claims that the other man is not her type - he is not pleased.
  • A variation was overused to the point of boredom on the original Fantasy Island, when Rourke reveals that a visitor's fantasy love interest just happens to be another visitor to the island.
  • Daytime soaps do this a lot. Most of the time it's not supernatural, just a way to bring back an actor who has been killed off, such as when Angie Hubbard of All My Children and The City met and married a man who looked exactly like her late husband Jesse. An example of the supernatural sort was on General Hospital when Anna's alien friend Casey had to return to his home planet, and then Anna met a lookalike human, Shep Casey.
  • Used in Wonder Woman when the series moved from WW2 to the (then) present day. WW's long-time Love Interest Steve Trevor had been established as an Army officer in the 1940s, so in order to have "him" around in The '70s, he had to be replaced by his identically-named son — both played by the same actor, of course.
  • Averted in the pilot episode of Time Trax, where Darien's Love Interest in his own time is killed by the Big Bad. He goes back to the 20th century, chasing the escaped criminals only to encounter her Identical Grandmother. Nother happens between them, although she helps him in a later episode.
  • In Fringe, "our" Lincoln Lee and "their" Olivia Dunham become this for each other.

  • On Star Trek: The Original Series, the end of the episode "Mirror, Mirror' had Kirk meet a counterpart of Marlena Moreau, a female crew member who had been his counterpart's "woman" in the Mirror Universe.
    • This comes up again in some of the Mirror Universe stories of Star Trek: Deep Space Nine. Sisko meets the counterpart of his dead wife, Jennifer, and Kira meets the counterpart to her dead lover, Vedek Bareil.
  • On Dark Shadows, Barnabas would attempt to invoke this trope several times and try to turn his love interests into his long lost love, Josette. The most notable of these attempts was Maggie Evans, who really was a doppelgänger for Josette.
  • A rather weird example occurred in Farscape. At one point, John Crichton gets split in two, with the implication that they are both "real." Soon after, the crew gets separated into two groups, each with one Crichton. Aeryn, who'd been growing closer to Crichton during the course of the series, finally consummates her relationship with the Crichton she's with. He eventually performs a Heroic Sacrifice, and the remaining Crichton finds it an uphill battle to win back her love.
  • Happens in Eureka when Henry and some others travel to 1947 and back, arriving at an alternate present. Henry finds his Alternate Universe self is married to a girl he barely knows. He tries to play the part of husband, but she confronts him and he spills the beans. She's married to a guy who doesn't know her. They get better.
  • This is, essentially, what starts the plot of The Vampire Diaries: Stefan returns to Mystic Falls after finding out about the existance of Elena Gilbert, a human girl who looks exactly like his deceased ex Katherine Pierce (later explained to be because they're descendants, since Elena was adopted, and both are Doppelgangers). However, he subverts this slightly in that he falls in love with her because she's the opposite of Katherine.
  • In Home and Away, Curtis leaves with a girl who's the exact double of his dead girlfriend (it's the same actress).
  • A variation in the Stargate SG-1 episode "Ripple Effect." Among the dozen other SG-1s from alternate realities who show up on the base, one of them has Martouf, a Tok'ra who developed quite an interest in Samantha Carter. Though they don't hook up in the episode, it does provide some nice closure for Sam (and the fans) since the regular-universe Martouf was killed before the relationship had a chance to develop.

    Tabletop Games 
  • This often happens with laterally reincarnated innerwalkers in Feng Shui.

    Video Games 
  • Deconstructed in Silent Hill 2, where James can choose to be with Maria, who is an idealized doppelganger of his dead wife Mary. In the ending Maria starts to cough, implying that James is doomed to relive the pain of her dying from a terminal illness just like his wife did. The game implies that this is what James just deserves for clinging to an image of his wife instead of moving on. Or, in another interpretation, refusing to accept responsibility for what he did, and failing to understand why what he did was wrong and selfish.
  • In the game version of Da Capo this happens in the Miharu route. Girl gets hit by car, girl gets replaced by robotic duplicate. Boy loves robot. Robot malfunctions. Girl comes back. Boy gets together with girl...
  • The NES game Astyanax ends with the hero back in his normal highschool world, but the new student is a dead ringer for the fairy companion who pulled a heroic sacrifice.. but the game never says whether perhaps she was just reborn or what.

Suddenly, he sees the Time Travel elevator from Season Two and finds there Max from an Alternate Timeline, in which Sam is the one who died. After an awkward moment, they decide to resume their mischief and pretend none of this happened.
    • By Poker Night 2, they remember the events with laughter, possibly blocking out the memory of losing their best friend.
  • In Princess Debut, either of the universe's love interests you end up with. Sabrina can either remain in the parallel universe and marry the prince she's closest to or return to her own world and marry the real-world version of the prince. Or the prince is the doppelgänger replacement of her classmate.
  • In .hack//G.U., after Haseo loses Shino to Triedge, he meets Atoli who happens to have the near exact same avatar design, save a color change. However, while her looks are similar, her personality is very different from Shino's, which causes Haseo to (initially) hate her. This trope is more justified in most instances in that it takes place in a video game where, like in real games, many characters are near Palette Swaps of others.
  • In Winter Shard, if Frederone's love interest Rosetta dies, Zewoe creates a clone of her to please him. This enrages Federone, either because he promised Rosetta that he wouldn't try to resurrect her or because he did resurrect her only for her to be Driven to Suicide because of her religious beliefs, and he actually orders Marliene to wear a mask at all times when around him because he doesn't want to be reminded of how much she resembles Rosetta. He can either come around to accept Marliene as a legitimate love interest in her own right, or he can reject her.

First Torg has a Cannot Spit It Out crush on Zoe, then he gets trapped in the Dimension of Lame and hooks up with that universe's Zoe, then Alt-Zoe is killed by Lord Horribus and Torg returns to his home universe, and starts crushing on Zoe all over again.
    • And it turns out Torg is this for Alt-Zoe as well, since her dimension's Torg vanished long ago after the two were romantically involved.
  • Danielle in Kevin & Kell.
  • Averted in Cuanta Vida. After Red dies, the new spy, Rojo, shows up. It doesn't end well.
  • In Relativity, Anne ends up treating Irina like this after she arrives from her Alternate Universe, since Anne was in the process of divorcing her universe's version of her, while Irina had last left Anne on good terms.

    Western Animation 
  • ReBoot: After Glitch-Bob's attempt to split apart via portal goes explodey, Dot decides to marry the other Bob. Dot was already leaning towards choosing the other Bob, and Glitch-Bob's accident pushed her the rest of the way. Then it turns out that the other Bob is actually the Big Bad. Whoops.
  • On Futurama, Fry (and the Professor and Bender) get hurtled into the future so far, they reach the end of the universe and watch a new, identical one come into existence. Fry gets together with the Leela from that universe (after the native Fry is killed by their time-machine's arrival). Uncharacteristically for this trope, though, we actually get to see the original Leela spend the rest of her life miserable and alone.
  • At the end of The Jetsons Meet the Flintstones, Judy Jetson is pining for her stone-age boyfriend Iggy Sandstone (met during a time-travel mishap), and then meets his identical space-age descendant, who's no less cool. Both boys are into rock music, of course.

    • In the third film My Little Pony: Equestria Girls – Friendship Games, the human Flash Sentry meets the human Twilight Sparkle and believes her to be Princess Twilight. He tries talking to her a few times but she is too busy doing her research to really talk to him. Flash does not realize this is a different Twilight till the end of the film.
    • It's deconstructed in the fourth film My Little Pony: Equestria Girls – Legend of Everfree. The human Twilight Sparkle may look and sound like Princess Twilight Sparkle, but she is ultimately a different person with different experiences and interests. Flash Sentry's attempts to talk to her the same way he did with Princess Twilight don't work, and she becomes interested in Timber Spruce, who seems to have more in common with her.
  • Parodied in the Adventure Time episode "The Suitor", in which Princess Bubblegum is annoyed by a Dogged Nice Guy pick-up artist who won't stop courting her. She finally makes him happy by giving him a Sex Bot in her form that only cares about romance.
