* ComicBook/MilesMorales has an ever-growing list of infatuations on superheroines his age: [[ComicBook/UltimateMarvel Ultimate]] [[ComicBook/AntMan Cassie Lang]], [[ComicBook/AllNewXMen teen Jean Grey]], [[ComicBook/MsMarvel2014 Ms. Marvel]], ComicBook/SpiderGwen, and [[Characters/MilesMoralesSpiderMan Starling]] are among the most prominent.
* [[ComicBook/MsMarvel2014 Ms. Marvel]] supporting character Zoe Zimmer is extremely unlucky in love. She has had feelings for Nakia ([[IncompatibleOrientation who is straight]]), Kaylee ([[EvilAllAlong who is actually a killer robot]]), Alanna ([[ChuckCunninghamSyndrome who disappeared after the arc in which she debuted]]), and Marissa ([[TheGhost who has only been mentioned in dialogue]]). Even Josh, the one guy she dated back when she was still in the closet, dropped out of school to become the supervillain Discord.

* ''Manga/AConditionCalledLove'': Hananoi is infamous at school for constantly dating around and being [[{{Yandere}} obsessively]] devoted to each girl he dates, to a fault. The manga deconstructs this trope by unpacking the [[InsecureLoveInterest insecurities]] and [[DesperatelyCravesAffection unhealthy thinking]] that would drive a person to behave in such a way and by making Hananoi very aware of his actions. He is not simply falling in and out of love and forgetting the past girl when he moves on. He is very intentionally acting to get his partners to love him by showering them with affection and he cuts out his previous partners from his life because for him, to love someone is to make them the [[LivingEmotionalCrutch center of your world]].
* ''Manga/DemonSlayerKimetsuNoYaiba'' has Zenitsu immediately forgetting about the previous woman he desperately asked to marry him upon finding a new target; the only one he hasn’t let go of is Nezuko, partially because he might like her more than his usual crushes on first sight and that Nezuko is a nice demon girl in a state of mind where she really can’t decide or understand complex things yet, she is just nice enough not to repudiate Zenitsu on sight.

->'''Bingo''': Her name is Myrtle. Isn't she beautiful!\\
'''Bertie''': What happened to Daphne?\\
'''Bingo''': Daphne?\\
'''Bertie''': The one who came after Honoria?\\
'''Bingo''': Passing fancy, Bertie, the folly of one's youth!\\
'''Bertie''': It was only a week and a half ago.

* Martina of ''[[LightNovel/{{Slayers}} Slayers Next]]'' falls madly in love with just about every male member of the cast she meets. The fixation on Zangulus at the end of the season lasts long enough to get her married off.

* Claire Stanfield from ''LightNovel/{{Baccano}}'' has a history of this, literally falling in love and proposing marriage to complete strangers, almost at random. He has a hard time convincing his brothers that his relationship with [[spoiler:Chane]] is any different other than that she didn't immediately say no.

* ''Anime/{{Pokemon}}'':

* ''WesternAnimation/PepeLePew'' from ''WesternAnimation/LooneyTunes'' falls instantly in true love with anything he ''thinks'' is a female skunk.

* ''WesternAnimation/GravityFalls'' has Mabel, also as a female example of this trope. However, "Society of the Blind Eye" shows she's not taking her failed attempts at a summer romance (like Norman, who "turned out to be gnomes", Gideon, who was a StalkerWithACrush who threatened her family, and Gabe, who [[CargoShip made out with his own puppets]]) as well as she lets on.

%%* ''WesternAnimation/PepeLePew'' from ''WesternAnimation/LooneyTunes''. At least until the tables are turned on him.

This character is a hopeless romantic. He's madly, passionately, ''fatally'' devoted to the girl he loves. It's just that the girl he loves seems to change from week to week. When one girl rejects him (which she usually does), he is heartbroken at first, but he soon finds a new love interest, and forgets all about the old one.

* ''Manga/DemonSlayerKimetsuNoYaiba'' has Zenitsu immediately forgetting about the previous woman he desperately asked to marry him upon finding a new target; the only one he hasn’t let go is Nezuko, partially because he might like her more than his usual crushes on first sight and that Nezuko is a nice demon girl in a state of mind where she really can’t decide or understand complex things yet, she is just nice enough not to repudiate Zenitsu on sight.
* ''Manga/{{Gals}}'' has Naoki, whose entire characterization consist of him falling in love with an unavailable girl, insisting that he and the girl are "soulmates", then inevitably getting heartbroken when he finds out that his "soulmate" already has someone else... before falling in love with another (unavailable) girl when he tries to leave for some soul-searching. Over the course of three volumes, he's fallen in love with Ran, then Miyu, then Sayo, then Aya.

* [[ComicBook/MsMarvel2014 Ms. Marvel]] supporting character Zoe Zimmer is extremely unlucky in love. She has had feelings for in Nakia ([[IncompatibleOrientation who is straight]]), Kaylee ([[EvilAllAlong who is actually a killer robot]]), Alanna ([[ChuckCunninghamSyndrome who disappeared after the arc in which she debuted]]), and Marissa ([[TheGhost who has only been mentioned in dialogue]]). Even Josh, the one guy she dated back when she was still in the closet, dropped out of school to become the super villain Discord.

* Discussed in ''Film/MammaMiaHereWeGoAgain'', Donna guesses Bill is this sort, and sums up the distinction between this trope and TheCasanova. "One who ''actually does'' fall in love every night, but always falls out of it the next morning." However, there's scant evidence that Bill is actually like this, but plenty of evidence that ''Donna'' is a female example. She seems to have genuine feelings for Sam, Bill, and Harry, despite meeting them all within a couple of weeks.

* ''Literature/TheDresdenFiles'' novel ''Literature/BloodRites'' features Arturo, who has been married (and divorced) thrice and currently has a new beau. People who know him claims that he is capable of intense love towards whoever he's got his eye on at the moment, but has a problem when the magic dies — it is notable that in a universe where ThePowerOfLove is real, Arturo is capable of showing it towards anyone he's interested in. [[spoiler:It is revealed at the end that for the first time, he married a ''plain'' woman. Perhaps this one will last.]]

* ''Literature/TheStormlightArchive'': Adolin is this in spades. Frequently lampshaded by his brother, and several other characters. In the second book he's fine with the prospect of an ArrangedMarriage to a woman from an insignificant house he's never met partially because by this point he's offended ''literally'' every other eligible woman, and the idea of letting someone else make the arrangements sounds good. Oddly enough, the ArrangedMarriage seems likely to become a PerfectlyArrangedMarriage, as he and the girl in question fit together quite well. There's a bit of a RunningGag throughout [[Literature/WordsOfRadiance the second book]] where Adolin will be in the same scene with a random woman and she'll glare at him. At one point, the woman teaching Kaladin's men how to care for their horses starts throwing stones at Adolin without missing a beat. In [[Literature/{{Oathbringer}} the third book]], Shallan mentions she tried avoiding Adolin's exes, but quickly had to give it up as impossible.

* In ''Literature/WillGraysonWillGrayson'' Tiny Cooper is constantly swooning after and being heart-broken over guy after guy (after guy after guy). Apart from his gay-ness and large-ness, this is practically his defining feature.

* ''Series/YediYuz'': According to Nil, Metin of "Biyolojik Saat" is one. He easily finds new women to date after a breakup, but slowly realizes that not everyone he attracts is a good match once he begins looking for a quality lifelong relationship.

* Dylan in ''Series/{{Lovesick}}''. Luke says he "falls in love twice a week". His ongoing love for Evie in the present is different, but in the many flashbacks he definitely fits this trope.

* Every woman Mark from ''Series/PeepShow'' meets might be The One. Even Jez has streaks of this, though he's just as likely to use a women for sex with plans to dump her ASAP.
* A strange example in ''Series/QuantumLeap''. Often, the purpose of the leap is to bring a couple together, or reconcile them. When the leapee is part of the couple, Sam has to become one of these, and usually becomes involved for real. He knows he himself can't stay, and [[AmnesiacHero he doesn't always remember the romance]] thanks to [[LaserGuidedAmnesia the "Swiss cheese memory effect"]]. A few times he's fallen for someone on his own account, even though the same pitfalls apply, [[spoiler: and he's married in his own time, though he doesn't remember that either]].

* "Romeo and Juliet" by Music/HoboJohnson discusses the trope namer's tendency to fall in love easily both by using it as a metaphor for Hobo's own string of failed relationships, and by suggesting that if the two characters survived the play, they would have gotten divorced.

* The TropeNamer is Romeo Montague from ''Theatre/RomeoAndJuliet''. At the beginning of the play he is desperately in love with a girl named Rosaline, who has rejected him. Soon after, he meets Juliet, and promptly dismisses Rosaline as a passing infatuation. Though this only happens once in the story that we know about, goodness only knows how many more times he would have gone through this had Juliet also rejected him.

* [[CasanovaWannabe Larry Butz]] from the ''Franchise/AceAttorney'' series is constantly either trying to get together with a woman with whom he's fallen madly in love, or just been dumped. We rarely see him actually ''in'' a relationship. This is a big part of his character, though: [[NewJobAsThePlotDemands He also has a different job every time we see him]].

* [[spoiler: Subaki's daughter]] Caeldori from ''VideoGame/FireEmblemFates'' is said to be [[SmittenTeenageGirl "the one who falls in love the easiest in the army"]], and in her own words, after having her first LoveConfession rejected, she's crushed on guys who were unavaliable to her for one reason or another. Naturally, when she actually falls in love in-story, she drops this attitude.

* Rosethorn, of the Literature/WhateleyUniverse, whose first name really ''is'' Romeo. He's strikingly handsome (or, as he is more often described, [[{{Bishonen}} beautiful]]), and has mutant powers. He tends to find Miss Right, make her over, improve her self-esteem, etc., until she dumps him. She always dumps him. Either she hates being the dumpy one in the relationship, or she becomes 'pretty' enough for other guys to see her as desirable, or the whole 'my mother is a dangerous supervillain' thing comes up and torpedoes the relationship, or...

Unlike TheCasanova, who strings many women along at the same time without caring about any of them, the Serial Romeo genuinely believes that each successive love is "The One", and that without her, life is not worth living. Expect this character to be completely [[GenreBlindness blind]] to the implications of having a new "True Love" every week. If called out on his fickleness, expect him to insist that his current love interest is the only person he has ever really loved, and to dismiss her predecessors as mere youthful infatuations. Expect much eye-rolling from his friends.

** In the manga, Minako tops her by a few orders of magnitude. During ''Manga/CodenameSailorV'' Artemis kept count of Minako's 'first loves' (as she called them), and the final chapter had him sarcastically congratulate her for her ''5,000th first love''.
