False Innocence Trick



The Hero has come upon an Innocent Bystander trapped in a Tailor-Made Prison by a wicked monster. The prisoner may plead with the hero to be set free, telling him all about the horrors the tyrant has inflicted upon him, or the prisoner may just hang in sorrowful Unwilling Suspension in his terrible bonds. Once the hero sets the prisoner free, it quickly becomes apparent that he was tricked.

The False Innocence Trick (aka Fake Good in A Can) is when a villain or monster locked away for a good reason feigns innocence or being a good guy in order to fool the hero into letting him go. Typically the villain will prey on the hero's good will and strong moral fiber while doing this by making himself and his story as sympathetic as possible. He often is also counting on the fact that the hero Did Not Do the Research or has come from a time/place far enough away to not know who the prisoner really is.

Contrast the more common Decoy Damsel, and Disguised Hostage Gambit for when a villain makes a genuine prisoner look like a bad guy.

Video Games

 * In Mortal Kombat Mythologies Sub Zero, Sub-Zero (the elder) is imprisoned in the Netherrealm. His fellow prisoner is normally Scorpion, but if the player decided not to kill Hanzo Hasashi, then the other prisoner is . He claims that he's an unjustly imprisoned soul like Sub-Zero and notes that he's playing Raiden's "game" for the time being. His manipulation of Sub-Zero indirectly helps.
 * In one quest in Oblivion, you can buy a house, only to find that it's haunted. Investigation reveals the corpse of a lich (imprisoned for being evil) who claim's he's turned good after having time to reflect on his crimes. Unfortunately Stupidity Is the Only Option if you want to complete the quest.
 * Paper Mario: The Thousand-Year Door: Although it appears that the "evil" beings trapped in the black chests were originally good, the end result is the same nonetheless. They plead for Mario to let them out, so of course, he does. They curse him as thanks. Kind of subverted, because the curses help you, to the point that you literally cannot continue without "acquiring" them.
 * It is also implied that they themselves are being forced to curse you, yet choose to do so in a manner such that the "curse" is more of a blessing in disguise.
 * In World of Warcraft, there's a quest in the Arathi Highlands where you're contacted by an earth princess named Myzrael, who seeks your help to escape her confinement. To free her, you kill some of her guardians and release her from her crystal prison, where you find out that she's evil. Sort of subverted though, in that she was driven to madness by the Old Gods, and now resides in Deepholm, where she is once again sane and good.
 * In The Legend of Zelda a Link To T He Past, this is how you trigger the boss fight with the boss underneath Kakariko village. You are told he kidnapped one of the descendants of the sages, and in some way you can say he did it, but he also disguised himself as the girl and hid himself in his own prison.
 * Happens on two different occasions in Baldur's Gate II:
 * The first time is while escaping from Irenicus' dungeon. You run across an imprisoned man in a rather luxurious cell, with a large number of booby-trapped treasure chests to boot. If you let him out, he shortly afterward reveals he's a doppelganger and attacks, with rather predictable results.
 * The second time is about halfway through the game, when.
 * in Myst try this.
 * Albion: In the prison in the middle of the desert "near" Umajo-Kenta, one of the prisoners is a pretty, sympathetic-looking woman who tries this, complete with a promise for a reward to make it sound like a typical RPG quest. If you let her go, once you get back to the city, you'll hear that the dangerous psycho is on the loose and run into a child whose mother was killed by her. Eventually she'll be caught again, leaving you with nothing for your trouble but a guilty conscience. What's more, with the trip through the desert so long and difficult, there's a higher chance than average that the player won't still have a saved game conveniently from before releasing her when seeing the results.
 * In Shadowgate, the room with the Golden Horn is also occupied by a beautiful young woman who is chained to the wall. If you try to grab the Horn, the "prisoner" will transform into a vicious werewolf that tears you apart. The only clue that something is off with the prisoner is that the description notes that she looks beautiful in moonlight.
 * This is the main plot point in the 2004 Bards Tale game.
 * In Batman: Arkham Asylum, you can see Clayface in a glass cell. But in fact, he changes his appearance each time the camera wanders away from him and tries to trick you into releasing him. Good thing the game doesn't offer you the opportunity to free him, or this troper would have done it.

Webcomics

 * In Girl Genius, Agatha mentions this trope when she first encounters Othar Tryggvassen, Gentleman Adventurer! who asks her to free him. She believes he's doing this and does not free him; however, he actually believes he's the hero being held by the villain.
 * Agatha does rescue him eventually, after learning some unflattering things about their mutual 'host'. He helps her escape at a later date in return. And then he tries killing her, so she throws him out of an airship. As it turns out, Othar is hardly a 'fake good'; his definition of 'good' just differs slightly from hers.

Western Animation

 * Teen Titans: Raven befriends a knight hero in a book by the name of Malchoir. He tells her stories of how an evil dragon trapped him there. He teaches her powerful magic and things seem awesome. Until,
