That your heart desires
But the consequences
Will surely be dire!"
These bad guys trap you by preying upon your desires. They know what you want and are willing to offer it to you—or so it would seem. They show you things you've always dreamed of, presenting you with the very thing that your heart yearns for. However, Be Careful What You Wish For. Temptation can be a powerful and dangerous thing, and is sometimes harder to resist than any overt danger.
This is a favorite technique of the Master of Illusion, who may use it to trap others in a Lotus-Eater Machine, or the kinds of monsters that get satisfaction out of manipulating their victims' emotions. After all, it's much easier to catch flies with honey than with vinegar, and the victim often won't even be able to realize the danger until it's too late. Even if s/he realizes it's not real, the power of the desire may entice them to remain "deceived." The Deal with the Devil also frequently runs on this trope, exacting a horrible price in exchange for one's heart's desire, frequently in a way that makes it not worth it in the end. This is why your parents always told you not to take candy from strangers.
- In Magical Girl Lyrical Nanoha A's, the Book of Darkness trapped Fate in a world where her Evil Matriarch of a mother loved her and the dead girl she was cloned from was her Cool Big Sis. Fate even admits that this is what she always wanted as she breaks down in tears. This was meant to be a case of Let Them Die Happy rather than any form of malice, but ended up being crueler than any torture could have been since Fate knew almost immediately that it wasn't real (and that it never would be). Although it does help Fate come to terms with being a separate person from Alicia and accept Lindy's offer to adopt her.
- In Nabari no Ou, the Shinrabanshou often tries to tempt Miharu into telling her his greatest desires, and then she will grant him her destructive power, regardless of whether his body can handle it.
- The Infinite Tsukuyomi from Naruto traps everyone on the planet in an endless dream while draining them of their personalities and defining features, transforming them into White Zetsu.
- Black Mamba of the B.A.D girls (seen in Cable & Deadpool, among others) can temporarily incapacitate people with an illusion of their ultimate fantasy. This failed to work on Shen Kuei / the Cat, a Gentleman Thief and martial artist who already is living his ultimate fantasy.
- In For the Man Who Has Everything a Lotus-Eater Machine of this sort is used on Superman, who hallucinates that he's back on Krypton.
- Rare hero example: Danielle Moonstar, AKA Mirage of the New Mutants, could create a mental illusion of your worst fear, or your heart's desire. She could choose which one, but even she couldn't know what her victim was seeing.
- In DC's Legion of Super-Heroes, when Shrinking Violet was under the influence of the Emerald Eye (unbeknownst to her teammates), she started granting the Legionnaires their hearts' desires. It went fairly well until Leviathan got his, which was to die as a hero. Attempting to bring him back to life, Violet was taken over entirely by the Emerald Eye.
- The X-Men annual Lost in the Funhouse revolved around this - Horde, the villain of the issue, sent the team to a Citadel to retrieve a MacGuffin on pain of destroying their world if they refused. The citadel's defence mechanism was offering intruders a vision of their heart's desire one-by-one. When it couldn't find Longshot's desire due to his "purity", it cut out step two and absorbed him.
- The Karma Of Lies: Lila Rossi manipulates her marks by figuring out what they want most and claiming that she can help them achieve their dreams with her supposed connections. She then proceeds to not only string them along with her scams, but directly sabotages their goals.
- Most of her classmates are tricked into donating to her Fake Charity drives; she also convinces many of them to trust her with their work/information that she then turns around and sells off, robbing them of the fruits of their labor. Others find themselves blacklisted as a result of her actions, getting blamed for the damage she caused.
- Adrien knows her true nature, but still gets suckered in when she feigns remorse, pretending that his 'high road' approach helped her realize the error of her ways... exactly what he wants to hear. She then sets him up as an Unwitting Pawn and The Scapegoat while making it appear that he's the one trying to frame her, helping shred his reputation.
- In an example unrelated to Lila, this also comes into play during the Final Battle with Mayura: Rose/Pigella uses her Gift to manifest a vision of what the villain wants most: Emilie Agreste.
- In The Princess and the Frog, when Tiana steals the magical talisman that Facilier needs for his Evil Plan, he conjures up a vision where she's a human again, in the dream restaurant that she's been working for years to open, and offers to give it all to her if she hands it back and lets him keep Naveen. At this point, however, she realizes that she needs her restaurant and Naveen to be happy, and tries to smash the talisman instead. Sadly for Tiana, Facilier's Living Shadow snags it before it hits the ground, but it isn't long before Tiana turns the tables and actually smashes it, causing Facilier and his shadow to be dragged to the Other Side.
- Legend (1985). Jack's heart's desire is his girlfriend Lili. When the fairy Oona and Jack are trapped in the dungeon of the villain Darkness, Oona offers Jack his heart's desire by assuming Lili's appearance and trying to get him to kiss her.
- The female 'space vampire' in Lifeforce took her appearance (her natural form is a winged alien creature) from the subconscious desires of the astronaut who found her. This gives him an unhealthy obsession with her, even after he discovers she feeds on Life Energy and is entirely capable of destroying the world.
Carlson: What are you? Why are you so human, so perfect? What were the bird-creatures on the [space]ship?
Space Girl: Our bodies are unimportant. As you and your men approached in your ship, we changed them for you. We entered your minds, and found there new bodies. I took my shape from your mind. I took your language. I became the woman I found there, in your deepest thoughts, your deepest...needs.
- In The Dresden Files. Primary modus operandi of the Denarians. The Shadows of the Fallen Angels are just as powerful and knowledgeable as their original forms, but need a willing Host to allow the Fallen to fully enter the person. While it could be lies on the Fallen's side, one way to break their Host is to offer them this idea. One White Court vampire who genuinely loves a mortal woman and is loved in return is burned by that Love they feel towards each other as it is a poison to his incubus demon within. While he is originally feels he could resist the Shadow's offer, when told it could grant him a way to be with his beloved and not fear being hurt by her love, he goes silent, recognizing the effectiveness of this tactic.
- Harry Potter had the Mirror of Erised, which shows the viewer whatever their greatest desire is. Ron, who feels overshadowed by his siblings, sees himself outdoing them all. Harry, who never knew his real family, sees himself with his parents and relatives. Dumbledore mentions that it can be highly addictive, however. Dumbledore hides the Philosopher's Stone "inside" the mirror as its final measure of protection—someone who wants to use its powers will just see themselves doing so, but someone who wants the stone for itself, without intent to use it, will magically obtain it.
- Larry Niven's Known Space series had a gadget called a droud, which stimulated the pleasure centre of the brain directly. Users quickly became addicted and eventually starved to death, immobile in a puddle of their own wastes. Humanity had given up trying to treat the problem, regarding it as Darwinsim in action in a society which was, in any case, hugely over-populated so there was no value is trying to save people who would have nothing to contribute.
- In The Whispering Skull from Lockwood & Co., those who are ensnared by a glimpse of the bone-glass hear a ghostly, whispering, wheedling voice urging them "Look. Look. I give you your heart's desire." Those who actually do look into it directly, either by their own choice or because they are forced to, die no more than a minute after.
- Stanley G. Weinbaum's science fiction short story "A Martian Odyssey" had a carnivorous plant monster that read the mind of its victim and created a mental illusion of what the victim most desired to lure it into the plant's clutches.
- In Pact, Faysal Anwar, Gatekeeper of the Seventh Ring, offers Blake Thorburn a choice of either immortality (by giving him the ability to return from death indefinitely) or humanity (by restoring the pieces of Blake that were torn away when Blake fell through the cracks in the world), if he'll come work for Faysal's master Johannes. To Blake, who ultimately just wants to be free, both are incredibly tempting not for themselves but what they'd allow him to do.
- The short story "A Part of the Game" in Dragon magazine #51. A group of desert travelers find an oasis which appears to be a gate to a utopian other world. Most of the group enters the pool only to be eaten by its inhabitant, a monster that can create beautiful illusions.
- In the novel Something Wicked This Way Comes by Ray Bradbury, the carnival tries to entice the boys by showing them exciting and marvelous things. Particularly Jim, who is fascinated by it, and who also has a desire to become older.

Orac: Join us, Soolin. We can fulfill your every desire.
Soolin: [Turning Orac off] You wouldn't know where to start.
- The Greeed from Kamen Rider OOO are all about this. They are basically ancient homunculi who feed on humans' desire indirectly via their Yuumies.
- Lucifer (2016). This is a shtick of the title character, who can look into someone's eyes and compel them to reveal this trope. This can vary from wanting to commit murder to wanting a cheeseburger.
- Red Dwarf:
- "Back to Earth" has a joy squid (opposite of the despair squid in earlier episodes.) Both had the same effect of trapping you in a hallucination until you die.
- The total-immersion video game BetterThanLife was pretty much this. Unfortunately Rimmer's subconscious can't accept a world where nice things are happening to him, so his worst nightmares start coming true instead.
- Star Trek: Voyager: In the episode "Bliss", the space-borne equivalent of a pitcher plant tricked the crew of Voyager into entering it by making it appear to them as a wormhole they could use to return home and be reunited with their loved ones. The only people unaffected were the Doctor (a hologram, but the creature tricked the rest of the crew into shutting him off) Seven of Nine and Naomi Wildman (who, only being familiar with life on Voyager, had no real desire to go to Earth) and a Captain Ahab-type alien captain who had been hunting the creature (and was thus familiar with the creature's tricks). It does briefly work on Seven at the end when the creature makes her imagine escaping from it, which she did genuinely desire at that point.
- A whole episode of the original Star Trek, "The Man Trap", was all about this, disguising itself as a woman who had been dead for some years in order to be protected by the woman's widower and to prey on her old flame.
- Supernatural: The Djinn trap their prey by making their deepest wishes come true—by putting them in a hallucinogenic trance while the Djinn drains all their blood over the course of several days. Dean was once caught by a Djinn who made him experience an alternate world where the Winchesters' mother was never killed by a demon.
- This goes all the way back to the Sirens of Classical Mythology. They would sing a song that made them irresistible to sailors, who would steer their ships toward the sound. Then the ships would hit the rocks surrounding the sirens and sink.
- In a great many stories Satan is said to know Your Heart's Desire in order to get you to sign a Deal with the Devil. Far too many stories to list, really.
- Several examples of Jackass Genie.
- Li'l Abner: On August 31, 1948, cartoonist Al Capp introduced the schmoo, a bewhiskered white blob of a creature that looked like a bowling pin with legs. Schmoos seemed to exist only to provide humanity with its every need. Capp said he came up with the idea of the schmoo when he was driving through the New England countryside and saw the abundance that the earth provided. People of all political stripes — communists and capitalists alike — saw the schmoos as an analogy critical of their beliefs. (The fact that "schmoos" rhymes with "schmooze" didn't help.) Schmoos were Explosive Breeders that laid eggs and could give milk. If they really loved you, they'd could lay a cheesecake. And if you expressed a desire to eat a schmoo, one of them would die of ecstasy just to provide you with the opportunity. Naturally, a schmoo Tastes Like Chicken. Fed up with all the controversy over a character he claimed was nothing more than a commentary on the abundance of nature, Capp carried out a Writer Revolt by slaughtering the entire species in December. The Other Wiki has a more detailed analysis of the schmoos here.

Interestingly, it is Elan who breaks the Order out of it by realizing his heart's desire (seeing his dysfunctional, broken family reunited) is too unrealistic to ever happen.
- Aladdin: The Series had a variant in one episode: a small, timid animal that can do this whenever scared, hoping to distract a perceived threat.
