Being in love is dangerous for a character.
"Are you in love with her? Because it's that level of stupid."
Occasionally, a 'main' character who more or less pulled his weight at the start of the series starts to feel affection for another, and the writers like the idea. Suddenly, his own personal plot starts to become almost exclusively about that
, and we have nothing to balance out the inherent goofiness and clumsiness that occurs dealing with his emotions. This has an extra layer of trouble if the Demographic
of the viewers isn't too heavily interested in the romance, or romance in general. On the other hand, other demographics can relate
This can send someone on the edge of Can't Catch Up
straight into a ditch and relegate him to the side lines of a story, especially if it's fairly clear that the writers haven't used the character for a while because they don't know what to do with him.
If it isn't focus where they're hurt, it'll be their common sense, as suggested by the trope title
. The love interest may be all wrong for him in reality, anything from making him, or trying, into something he's not, or worse, outright using him
. When friends of the character try to snap him out of it, they will be accused of jealousy
by the lovestruck victim.
Extremely common in shonen
, when she's one of the three or so main characters
. A female character in particular often becomes a Faux Action Girl

. For a specific form, see Cannot Talk to Women
Granted, Dumb might be better than the alternatives

Anime and Manga
- Dragon Ball Z: Krillin had the chance to shut down Android 18 and stop Cell from ever reaching his Perfect form. But because he developed feelings for her, he destroyed the only chance to stop it from happening.
- At one point in the Yu-Gi-Oh! GX anime, a creature was introduced that literally made other creatures dumbstruck with love. She was (appropriately) called the "Maiden in Love" and any creature (male of course) that attacked her would then fall under the control of the player using the Maiden.
- Miyagi, Sakuragi, Aouta and Haruko in Slam Dunk. The mention and/or sight of their crushes can make them reach varying stages of ditziness, no matter where they are. Of course, according to fangirls, in the boy's cases it's sweet and funny, and in Haruko's case is an horrible sin.
- Ohgi of Code Geass was the voice of reason of the Black Knights, until he encountered and fell for Villetta. Needless to say, he became one-track minded soon after and made some incredibly rash decisions.
- Sakura in Naruto cemented her reputation among fandom as a mostly-useless character when she missed two easy attempts to kill Sasuke because of her perpetually one-sided feelings for him, and then afterwards admits that she can't do anything to save or stop him after all.
- Dr. Tofu from Ranma ˝ is arguable, since one of his traits from the start was the inability to function properly around Kasumi. Swiftly becomes a moot point, once he's replaced as the show's source of arcane knowledge by Cologne.
- Ryoga Hibiki does some pretty dumb things because of love as well. His unrequited desire for Akane's heart is his biggest emotional target, and he tends to go crazy when he thinks there's some sign she truly does love him back. At one point, he even considered staying in the Cursed Tunnel of Lost Love because Akane was frightened by the ghosts and kept clinging to him for protection and comfort — he figured that if he and Akane stayed there forever, she would always be turning to him for comfort. He gave it up mainly because the others caught him before he could run off with Akane and get lost in the tunnel.
- Rosario + Vampire:
- Tsukune Aono before his power up. He doesn't come off as dumb at first, but common sense and obvious logic are trumped whenever Outer Moka is in trouble. We're talking to the extent he would take on the equivalent of a M1 Abrams Tank with a slingshot. He never gives up despite how bad the last time was.
- Likewise, the various members of Tsukune's Unwanted Harem often end up doing some pretty idiotic and non-logical things in their attempts to win him over. For example, in Capu2 episode 8, Mizore, Kurumu, and Yukari get in a big fight in the human world over him and end up nearly breaking The Masquerade when they decide to use their powers.
- This is pretty much the entire plot of School Rumble. And neither Kenji nor Tenma was particularly bright to start with, leading the series down some truly bizarre roads.
- Esmeraude (Emerald) in Sailor Moon R. She was so in love with Diamond that she hastily accepted Wiseman's tiara to become more powerful than Sailor Moon and thus, winning Diamond's heart. Unfortunately, her plan falls apart when the tiara transforms her into a dragon rather than a Queen. The senshi (with the help of Tuxedo Mask) defeat the dragon and Esmeraude is momentarily restored to her human form - only to fall into a dark abyss. She whispers Diamond's name as she vanishes. To Esmeraude's credit, the rest of her peers including Diamond also made the colossal mistake of trusting Wiseman.
- From the strange and supernatural manga, Sex Pistols, one part-time protagonist Seth decides, after his boyfriend tries to break up with him, to knock-out said boyfriend, kidnap him, take him half-way across the world into a war zone in Saudi Arabia, lock him up, and then forget to tell him that the reason why he's locking him up is that as soon as he entered the country an entire faction of Seth's family have been trying to kill him! Nice one, Seth. And no, he wasn't aiming for an If I Can't Have You ideology either. Probably.
- In the Area 88 manga and OVA, Ryoko has very idealistic and immature ideas about love. To boot, she is determined to free Shin from servitude at Area 88, but never stops to ask why he might be in the Asranian air force in the first place. Finally, in manga issues that did not make it stateside, Shin repeatedly breaks her heart, and yet she reunites with him in the end.
Film - Animated
- Shang in Mulan is a mild form of this trope. He is a competent and professional soldier, not even letting his father's death distract him from the task at hand. But when he tries to thank Mulan after saving him from Shan Yu and when he later visits Mulan's house, he stammers and generally has no idea how to act around Mulan now that he knows she's a girl.
- The titular character in Roadside Romeo. His love interest tells him that if he truly loves her, he'll have to sing on stage with her at a club. When he gets there, his friends desperately tell him not to because he'll make the Big Bad furious and bring out his jealousy. Romeo has to decide to walk away from the dog and find someone else, or risk his life for someone he's only met twice, and has only known for about three minutes. Guess what happens.
- Sherman in Mr. Peabody & Sherman: Mr. Peabody is quite surprised that Sherman eagerly tried to save Penny from marrying King Tut, especially when she wouldn't even give him the time of day. However, when trapped inside a pyramid, a bashful Sherman wants to give up, and Peabody's questions lead him to act very goofy.
Film - Live Action
- Hellboy: Oh, Abe Sapien. Friend or Idol Decision, Hostage for MacGuffin, The Villain's Sister, Cosmic Keystone, and here you were making a fool of yourself for love.
- Crazy Stupid Love: It's even there in the title.
- A Knight's Tale: William fully understands this trope, as after making a faux pas to Jocelyn, she tells him that if he loves her, he'll lose. And so, at the beginning of the next tournament, after the flag for William's first joust is dropped, and his opponent spurs on, the four members of the Five-Man Band cheering William on...
Roland: "What are you doing?"
William: (sitting on his horse, going nowhere) "...Losing."
Wat: "I don't understand."
William: "...Neither do I." CRASH!
- In Stargate Continuum, Baal uses Time Travel to maneuver himself into dominance of the Goa'uld System Lords and is in position to conquer Earth with ease. He even brilliantly gains the loyalty of the Free Jaffa movement by dealing with them in complete honesty. His only failing was to let his feelings for Qetesh override his common sense, resulting her betraying and murdering him.
- Eddie in The Color of Money has this with his girlfriend, Carmen. He sees her as a Purity Sue, blinding himself to her Street Smarts and delinquent past. She's even wearing a necklace she stole from his mother, and he thinks it's just a coincidence.
- Pretty much the plot of the seventh book in the H.I.V.E. Series. Otto thinks that the reason Laura was acting strange around him was because he confessed his love to her and it didn't go well, but it was actually because she was being blackmailed by a member of the staff and her family was being held hostage. His lack of attention led to the death , injury or capture of 36 Alphas, and his own expulsion from the HIVE.
- This is parodied in Plague in the Gone series.
Virtue: "I'm going to refuse to do puberty. It makes you stupid."
- Older Than Steam, thanks to Francois Villon's The Great Testament:
Foolish love makes beasts of men:
It once caused Solomon to worship idols,
And Samson to lose his eyes.
That man is lucky who has nothing.
- This could be said for Daisy from The Great Gatsby, though she could simply be like that all the time.
- Even more so for Gatsby himself.
- He was never a main character, but Captain Typho, Padme's eyepatched guard in the second two prequels, fell in unrequited, unnoticed love with her, as revealed in the Star Wars Expanded Universe. After her death and funeral, he observed that she had died of being strangled, but there was no evidence of this on her skin, which meant the Force. Remembering that Anakin Skywalker had been scheduled as guarding her, he decided to track him down and hear the explanation, then either kill him or not depending on the answer. Keep in mind that this is after Order 66. He knows it's a long shot, and he knows that if Padme had known he was in love she would have urged him to let go and live his life, but he feels like he has to do this. Later he decides that Skywalker must have been killed, and Padme soon after, by a Sith, and he must find and kill this Sith - Darth Vader, specifically. The narration lampshades this once.
After all, no one in their right mind deliberately sought to make acquaintance of a Sith. But Captain Typho was not in his right mind. He was in love.
- Notably, while love gave him a goal both very difficult and quite suicidal, it didn't make him stupid. He was able to best the bounty hunter and Jedi killer Aurra Sing, stealing one of her lightsabers and clipping her biocomputer, though he did not kill her. He was cautious and planned, and was able to remember enough about the customs of different species that he could get plenty of information out of them. And he was even smart enough to acquire an obscure Power Nullifier for Force-users, knowing full well that a muggle can't beat a Sith Lord in a straight fight.
- In the Books of Pellinor, Hem repeatedly risks both his life and his mission to rescue Zelika because he loves her, even though he has no way of knowing whether she is even alive. As it turns out, she was killed soon after her capture.
- In the Dragonlance novels, Laurana's love for Tanis Half-Elven causes her to make the incredibly stupid decision to trust her Arch-Enemy Kitiara.
- Invoked in The Belgariad when Ce'Nedra asks Garion what's wrong with his friend Lelldorin. Lelldorin comes from the Arendish culture, known for Honor Before Reason, and Ce'Nedra comments that he's "so Arendish, he's practically incapacitated." Garion replies that Lelldorin is in love, and being in love makes some people's brains seem to leak out of their heads. Ce'Nedra, who just recently realized she's in love with Garion, is NOT pleased.
- Lazarus Long, in Time Enough for Love, has traveled back in time over two thousand years to visit his original family in 1917. What he doesn't count on is that, in doing so, he falls in love with his mother. This causes him to enlist in World War I to win her approval, despite having no personal stake in the war, knowing the outcome, and not knowing the future from his own personal point of view. He nearly dies as a result.
- In the story "The Warlock's Hairy Heart", seen in The Tales of Beedle the Bard, a fairy tale book for wizards and witches, the warlock believes that Love Makes You Dumb, so he performs dark magic to prevent this from happening to himself. It didn't end well.
- In Gene Stratton Porter's The Song of the Cardinal, the young cardinal believes this even while envying the already mated birds.
As for the doves that were already brooding on the line fence beneath the maples, the Cardinal was torn between two opinions.
He was alone, he was love-sick, and he was holding the finest building location beside the shining river for his mate, and her slowness in coming made their devotion difficult to endure when he coveted a true love; but it seemed to the Cardinal that he never could so forget himself as to emulate the example of that dove lover. The dove had no dignity; he was so effusive he was a nuisance. He kept his dignified Quaker mate stuffed to discomfort; he clung to the side of the nest trying to help brood until he almost crowded her from the eggs. He pestered her with caresses and cooed over his love-song until every chipmunk on the line fence was familiar with his story. The Cardinal's temper was worn to such a fine edge that he darted at the dove one day and pulled a big tuft of feathers from his back. When he had returned to the sumac, he was compelled to admit that his anger lay quite as much in that he had no one to love as because the dove was disgustingly devoted.
- In Blood Promise, Viktoria Belikova falls for a casanova and is ready to be impregnated at age 17. When Rose rescues her, she accuses her of leading the casanova on and not understanding love.
- In City of Lost Souls, Jace has been Brainwashed by Sebastian, who is about to bring his Evil Plan to fruition. Jace manages to escape Sebastian's control temporarily, and wants to flee with the MacGuffin back to the Shadowhunters in order to prevent The End of the World as We Know It. However, afraid that the Shadowhunters will kill Jace to stop Sebastian, Clary keeps him from getting away, assuring that he ends up back under Sebastian's mind control and ultimately allowing Sebastian to advance his plan to the next stage.
- Alluded to in Harry Potter and the Half-Blood Prince, where said prince's notes in an old Potions textbook have allowed Harry to become top of the class. When he has to hide the book to protect his secret from Snape, his performance in class predictably drops; Potions master Professor Slughorn, however, sees nothing odd in this, as it starts shortly after Harry begins dating Ginny Weasley.
- Kate from LOST started out as one of the main characters in the ensemble, a fairly solid example of a Troubled, but Cute girl. However, as the series entered its second season, she became increasingly obsessed with Jack. Her attempts to rescue/ingratiate herself with/impress or otherwise have contact with him have led to an ever-growing list of problems that are completely her making—she seems to think she's back on a junior high playground (albeit one where she gets to have sex with Sawyer, the Jerk with a Heart of Gold, before going back to see what Jack is up to), not trapped on an island with a group of psychotics and a bunch of Epileptic Trees.
- This is taken to new lows in the season 5 finale, when a group of Losties ends up in the past thanks to some pesky time-travel, and they have to decide whether or not to detonate a nuclear bomb, whose explosion might change the future and prevent everything they've gone through to happen. Jack finally admits that his main reason to do it is that he lost Kate's love. Juliet's reason is that she noticed Sawyer, her current love interest, looking at Kate in a certain way. Kate and Sawyer go along with the plan. Sadly, Miles and Hurley reluctantly agree instead of pumping these emo douchebags full of hot lead.
- Damon's love for Elena or Katherine in The Vampire Diaries means he fits this trope as well as Love Redeems, Love Makes You Crazy, and Love Makes You Evil, which he has also played with at some point during the show.
- Klaus can fit too, as he has been manipulated by Caroline a couple of times after developing a feelings for her.
- And as of season 5, Katherine, who decided to stay in town instead of running away with Nadia after stealing Elena's body, all because she wanted to woo Stefan.
- Ianto's love for his girlfriend in Torchwood leads him to hide her in the basement of a heavily armored and base filled with alien tech. She's a half-converted evil cyborg woman. He then proceeds to date the guy who kills her.
- And Tosh secretly bringing her secret alien girlfriend to work, despite her suspicious resemblance to a serial killer on the loose. And the questionable security movements made by Gwen and Jack for Rhys and John respectively.
- In Smallville, this is a continually growing problem with Clark to the point that, in the first half of Season 8, he was finally starting to act a little bit like Superman until Lana returned at which point he lost about 7 years of character development. In fact, Lana is acting more active than Clark is, but that's a whole other set of issues...
- A smaller example: Chloe Sullivan, usually highly Genre Savvy, gets dumb when she is romantically involved with Ian, Jimmy and Davis. Also makes her into a Horrible Judge of Character for the first and third occasions.
- Pushing Daisies has this as a main element, in a subtle way... until "Water and Power", when the anvil is dropped on Emerson Cod's foot. The Narrator even points this out.
- Nobody, least of all the writer responsible, has any idea why Marian, in the 2006 BBC version of Robin Hood ran up to Guy of Gisbourne, an unhinged man who was obsessed with her, and began yelling: "I love Robin Hood! I'm going to marry Robin Hood!" Guy responded by running her through with a whopping great sword.
- Wilson references this in season 4 of House after House thinks that his attraction to a female doctor is interfering with his diagnostic skills.
"Boy meets girl, boy gets stupid, boy and girl live stupidly ever after."
- There also was an indirect, but very literal version in the episode where the patient of the week was a former prodigy and teen genius, now working as a FedEx deliveryman. Turns out that he'd fallen in love with a girl who had maybe 1/3 of his IQ, and started habitually using a drug made from a combination of prescription-strength cough-syrup and strong alcohol (known as 'Astro-Tripping' or 'Blue Drank') to slow his mind down to the point where he could relate to her. Of course, using something like that on a daily basis for years can take its toll...
- Suzy Pepper of Glee had a crush on her teacher, called him at 3 a.m., gave him a tie with red peppers so when he wears it he can think of her. Teacher rejected her, she ate world's HOTTEST PEPPER, burned holes in her esophagus, and got put in a medically induced coma for 3 days. To add insult to injury, the teacher then added that girls are so fragile.
- Lister references this in Red Dwarf:
It's really debilitating, being nuts about someone. You lose twenty I.Q. points every time you talk to them.
- Played with in Frasier, where Frasier is constantly doing face-palmingly stupid things whenever he gets into a relationship with a woman and directly ignoring his very own psychiatric advice...and he knows it, and can't help it, and constantly hopes his romantic plans won't blow up in his face this time, no matter how many times his Genre Savvy little brother reminds him how badly he suffers from this trope, with his stupidity probably reaching a zenith in "Don Juan in Hell". This is just one aspect of pretty much the very core of Frasier's character — being brilliant at giving other people advice, and terrible at following it himself.
- On Gilmore Girls, Lane is so smitten with a boy that she pets his hair when he's turned around, then runs away, embarrassed. She winds up turning to Lorelai for advice, who advises her that when it comes to love, "it pretty much all comes out in stupid."
- Sherlock states this outright in A Scandal In Belgravia. It is directed at Irene Adler who has just finished tearing into him about his apparent asexuality, something repeated throughout the episode.
- In Game of Thrones, King Robb Stark falls in love with Talisa Maegyr and marries her, despite having already promised to marry Lord Walder Frey's daughter, which doesn't only make him lose an important ally, but also gets him, his wife, his mother and most of the Northern army killed when the Freys murder them during the reconciliation wedding.
- Dawson from Dawson's Creek was an example of this from time to time, but averted it a lot early on. While watching a film noir with Pacey, Dawson couldn't figure out why the detective was so oblivious to the fact that the girl setting him up.
- Friends: Monica and Chandler when they first develop feelings for each other.
- Star Trek: Deep Space Nine: Odo becomes smitten with the Female Changeling during the occupation of Deep Space Nine in "Behind the Lines" and "Favor the Bold." He becomes so absorbed in linking with her that he neglects his duties. He became involved with her despite full knowledge of the Dominion's tyranny and the Female Changeling's prior antics. Fortunately, he snaps out of it upon realizing what the Female Changeling and the Dominion have in mind for the Alpha Quadrant.
- Scandal: Poor Huck. He wanted to believe that his girlfriend Becky was the best thing in the world. But he discovers that she not only shot the President, but set him to be the fall guy. She actually wanted him to come with her, and he was torn over what to do. The good news is that he did the right thing, which was to try to take her down. The bad news is that she caught wind of his attempt, and not only got away, but even murdered the entire family that he keeps an eye on!
- One common interpretation of Shakespeare's Romeo and Juliet has this trope as its lifeblood.
- In Little Shop of Horrors, all Seymour wanted to do more than anything in the whole wide world was to win Audrey's heart, and blindly listens to Audrey II's demands of feeding it lots of blood.
- Baldur's Gate features Viconia, a Neutral Evil Drow Cleric on the run from her equally evil race. Then the Player Character saves her a few times, worms his way into her dark heart, and if he plays his cards right, he can change her alignment to True Neutral... which disqualifies her from using a powerful, one-of-a-kind holy symbol dedicated to her (still evil) goddess.
- The whole plot of the sequel is essentially caused by the elven queen Ellisime sparing a villain's life out of love, exiling him instead (and doing nothing about his High Mage powers). At the end of the game she publicly admits her mistake, though.
- The title character of Max Payne in the second installment probably qualifies. He repeatedly notes that his feelings for Mona are driving him into one mess after another.
- In Pokémon, this is what happens if a Pokemon is hit with the move Attract from a Pokemon of the opposite gender, or if the attacking Pokemon uses a move that require physical contact (e.g. Tackle) onto a Pokemon of the opposite gender with the Cute Charm ability (though it works only 30% of the time in this case).
- Luisa Fortuna of Red Dead Redemption is shown to be deeply in love with Rebel Leader Abraham Reyes, a man who can barely remember her name and is clearly a power-hungry egomaniac. She even goes so far as to try and attack armed soldiers with a knife in an attempt to rescue him.
- In Theresia: Dear Emile, Hot Scientist Maylee says this word-for-word after she has sex with the main character of the Dear Martel story.
- In Persona3 FES, near the climax of The Answer, Yukari's character is completely derailed in a way that makes no sense due to her love for the protagonist. She selfishly wants to use the chance to she has to go back to the moment the MC sacrificed himself and stop him from doing it, regardless that this will definitely cause Nyx to return and destroy the world. This creates a Conflict Ball that results in SEES fighting one another and nearly ending their friendships.
- Selvaria in Valkyria Chronicles. She's utterly devoted to Maximillian, but she doesn't realize he doesn't return her feelings until he sends her to use a Suicide Attack, showing once and for all that he doesn't give half a damn about her personally. You'd think that'd be a bad move on Max's part, considering that Selvaria could turn him into a Mc Nugget combo with less effort than it takes for her to get dressed in the morning, plus she's developed a tenuous rapport with her counterpart on the good guys' side and could probably defect to their side. But no. She goes ahead and blows herself up, tearfully praising Max's name, but makes a point of betraying him at the last second by sparing the only people in the Gallian military capable of stopping him.
- Snap from ChalkZone goes stupid every time Queen Rabsheeba shows up. Usually stuff like eating his magazine, turning into dust, etc.
- The Grim Adventures of Billy & Mandy makes fun of this trope. In the movie "Big Boogey Adventure", Grim and Billy have this conversation referring to Irwin's big fight scene.
Grim: Love makes people do all sorts of stupid things.
Billy: I love everything.
- Referenced in Futurama, although the circumstances and Fry's general level of intelligence stop it being an example.
The Worm King
: He's bluffing! No creature would willingly make an idiot out of itself!
Fry: Obviously you've never been in love!
- Non-romantic example: In the My Little Pony: Friendship Is Magic episode Twilights Kingdom Part 2, after experiencing Fluttershy's friendship, Discord is so eager to have Tirek for a friend that he becomes Genre Blind to the possibility that Tirek would double-cross him.
- South Park: In "The Succubus", the typically Genre Savvy Chef falls for a succubus, who has this effect on him, albeit via More Than Mind Control on her part. It takes the boys exposing her to get him back to reality.
- Truth in Television, maybe? This article claims it is.
- Everyone in this Cracked article: "The 6 Biggest Over-Achievements in the History of Marriage". From entry #6:
Why was [the Earl of Snowdon] so full of himself that he took marrying a princess for granted? Some say ego, some blame Margaret, but his prep school classmates probably have the real answer here: He had a monster dong. And that lets you get away with anything.
- While it might be a better example of Lust Makes You Dumb instead of love, people who live in more rural areas will tell you that you're most likely to hit a wild animal crossing the road during the spring. Since spring is mating season when most female mammals go into heat, it would start to appear that the idea of mating starts to override an animal's basic common sense and self-preservation.
