Decoy Damsel

Bob the adventuring hero is approached by Alice, who is in some kind of trouble. Her village is being ravaged by a monster, or she's being forced into marriage against her will. Bob, like a good hero, goes to help her... except, whoops! It was all a lie. Alice isn't in trouble; she's the mastermind, and Bob just walked straight into a trap. No, not that kind of trap or that kind of trap, usually.

This is when a seeming Damsel in Distress is actually luring the hero in for her own ends, usually by playing on his heroism (and sometimes his lust for her). Almost Always Female. Compare Femme Fatale, Honey Trap and Wounded Gazelle Gambit. A subtrope of Using You All Along.

Due to the nature of the trope, spoilers ahead.

Anime and Manga

 * In one episode of Sailor Moon, Zoicite seeks to lure out Tuxedo Mask by pretending to be Sailor Moon and "rescue" people, and then he makes it look like he's captured. He then attacks Tuxedo Mask when Tux tries to save him, thinking he's Sailor Moon.
 * In Full Metal Panic!: The Second Raid, Yu Lan does this to one of Mithril's agents when he "rescues" her. Turns out that she was with Amalgam, and had been disguising herself as one of the ambassadors who were kidnapped in a hostage situation. It's obvious before the poor sap got his throat slit open that he was very satisfied with having rescued such a beautiful Damsel in Distress. She even gives him a flirty, appreciative look after he unties her.
 * Yu-Gi-Oh! 5D's:  from the Crashtown Arc.
 * from Mirai Nikki. Looks and acts like a Yamato Nadeshiko, is a Manipulative Bitch.
 * There's an entire village of these in Tengen Toppa Gurren Lagann, all under Guame's control. They fool every single male on the Dai-Gurren (except for Leeron).
 * In Ratman, main character Shuto is tricked into joining the "evil" organization Jackal when his classmate, Mirea Mizushima, is abducted by them. Not only is she the little sister of Jackal's leader, but was the one who suggested that they recruit Shuto to be inducted as the titular Ratman. It's ultimately a Subverted Trope, however, as she's a genuine Nice Girl and Jackal's members are more Anti-Villains than anything. Plus, by becoming Ratman, Shuto is able to (sort of) live his childhood dream of being a superhero.
 * Minatsuki "Hummingbird" Takami from Deadman Wonderland. She plays up her Shrinking Violet role for all it's worth when she's matched to fight Ganta; she acts like she's horrified by the violence, and adds in some clumsiness and sexual tension to really throw him off. Not only was it a complete act, she's crazy as hell and in prison for a very good reason.
 * Lily is introduced as such in the Fatal Fury first OVA. In a subversion,

Comic Books

 * from the Sin City story "A Dame to Kill For".

Film

 * Elsa in Indiana Jones and the Last Crusade. Albeit she's not the Big Bad.
 * And she explains that she isn't really a Nazi, but just wants recognition for finding the Holy Grail and believes that the Nazis are the best equipped to help her do that.
 * Brigid O'Shaughnessy in The Maltese Falcon.
 * Meg in Disney's |Hercules is genuinely in trouble the first time Hercules helps her out, but she later plays a Decoy Damsel to lure Hercules to a rock slide and a hydra, with help from Pain and Panic as Decoy Kids. She's not happy about having to do it, and it isn't her idea, but she did make a Deal with the Devil.

Literature

 * In the book The Last Knight, the hero rescues a woman from captivity in a tower, only to discover that she was being held there as a murder suspect. The rest of the book is about him trying to recapture her and bring her to justice.
 * Dilvish, the Damned is a collection of fantasy stories written by Roger Zelazny. In one of the stories, Dilvish hears a Damsel in Distress. His Genre Savvy sidekick, Black, a demon horse, warns him about this, stating that it is the oldest trick in the book.
 * Older Than Radio: Milady De Winter in The Three Musketeers.
 * The Jack Reacher story Echo Burning plays with this - there's an on-again, off-again question about the leading lady's actual motives for recruiting Reacher.
 * Senna from Everworld. Played With because she really is in trouble, but she has full intentions of becoming the Big Bad herself, and is manipulating the heroes to achieve that goal. Made worse because they know this but really have no choice but help her, since letting Loki or Ka Anor get her is potentially even worse.
 * In Replica, the evil Annie Perraut was able to fool Andy just by Clark Kenting (as all characters are clones, she looks like the prisonners). Basically, just because he wanted once an helpless Amy who would see him as her savior, rather than the proud one who was his girlfriend once.
 * C.L. Moore's 1934 story Shambleau - generally acknowledged as epoch-making in the history of Science Fiction - begins in what seems a classical Damsel in Distress situation: The protagonist, space adventurer Northwest Smith, sees a "sweetly-made girl" pursued by a lynch mob intent on killing her and intervenes to save her, but finds her not a girl nor a human being at all, but a disguised alien creature, predatory and highly dangerous. Soon, Smith himself needs rescuing and barely escapes with his life.

Live Action TV

 * Buffy the Vampire Slayer famously pulled this off in its first scene, playing on a horror movie stereotype—a blonde, timid Catholic school girl sneaks into a scary place with a bad boy. The twist? She's a vampire (Darla, specifically), and the boy doesn't live long enough to see the opening credits.
 * In Buffy's spinoff series, Angel, this trope is pretty much played straight. The Beast, in the guise of Cordelia, seduces Connor and uses him as a tool against the protagonists.
 * In the Alias Smith and Jones episode "How to Rob a Bank in One Hard Lesson", Heyes and Curry are hired for protection by two women, who are actually luring them to an isolated spot so that they can hold Curry hostage while Heyes helps them rob a bank.
 * In one episode of Psych, Shawn and Gus are hired by a woman who wants them to contact her dead husband from beyond the grave and find out where he hid the money from a robbery because she thinks his old partners are after her. It turns out the widow was the mastermind of the robbery.
 * In the Legend of the Seeker episode "Bounty", Richard helps a young woman who claims her brother was captured by monsters, who actually wants to turn Richard in for the reward.
 * Saffron from Firefly, who in her first appearance
 * Fiona of Burn Notice has been known to pull a heroic version; also, Michael fell for one in the episode
 * Michael ended up the victim of one again in the season 5 episode
 * This kinda, sorta happens in Robin Hood in which Guy of Gisborne is threatening Robin and Marian whilst they're hiding in a tree. The two of them play on Guy's Unrequited Love for Marian and pretend that Robin is holding her hostage, allowing Guy to play the hero and "rescue" Marian whilst Robin makes his escape. It's not a totally straight version of this trope considering that they're not trying to "trap" Guy, but they do successfully trick him by using Marian as a decoy Damsel in Distress, and it is all her idea.
 * In the Robin of Sherwood episode The Witch of Elsden, the outlaws find a distressed young woman in the forest who claims that she is fleeing Guy of Gisburne. Will is quite taken with her and seriously put out when it turns out that
 * This was a regular part of the stunts on Candid Camera. In one instance, a frail blond Damsel in Distress would be deposited on some street corner with two large suitcases. The suitcases looked identical, but one was empty and the other would be filled with concrete, weighing at least 200 pounds. When some big strong man approached, she would ask him to help with her suitcases ... then she would pick up the empty suitcase and walk away, while the hidden camera recorded the reaction of the poor schmo as he tried to pick up the other suitcase.

Newspaper Comics

 * Candorville has an accidental example in a flashback. Artemis Kenchu, self-proclaimed vampire hunter, slays several vampires in New Orleans and rescues the girl they tried to kill. As it turns out, she's a vampire too, but she's so evil they decided to kill her, and he's about to be her new servant.

 * In The Legend of Zelda: A Link to the Past, Blind tries to pull this on Link, disguising himself as one of the maidens he's supposed to be rescuing. Somehow Blind overlooks the fact that all the genuine maidens, including the one he's keeping from Link, are sealed in crystal, which kind of gives him away.
