Trap Door

"In a RPG and just arrived at a castle Hayley: (Reads the giant sign above the door) "Roodpart"? What does that mean? Jeff: It is probably some mystical ancient... Hayley: Oh Crap! It's "Trap Door" spelled backwards! Hayley and Jeff immediately fall through a trap door"

- American Dad

The Trap Door is an easily activated door in the floor of the Supervillain Lair, activated by a convenient switch or lever. Though a favorite of the Diabolical Mastermind, it might also be installed in the office of a Corrupt Corporate Executive. Somehow the hero (or minion who has disappointed the Big Bad) will always be sitting or standing exactly where the trap door opens, where it will usually lead to the Death Trap. If generous, the trap door will include a slide, otherwise it's just a drop.

And somehow, the seams around the trap are always invisible before it opens and after it closes. This is easier to do in animation, of course, unless it's given away by a Conspicuously Light Patch.

Mostly spoofed these days, often with a pun so old it creaks; "Nice of you to drop in!" Also often subverted by Trap Door Fail - having the would-be victim end up standing next to the trapdoor when it opens.

Not to be confused with the series about one of these working in reverse.

Anime and Manga

 * Used straight/spoofed in The Castle of Cagliostro, where the count just happens to have a trap door right underneath where Lupin stands in Clarisse's chamber.
 * Besides this one, the Count's castle is rife with secret passages and trap doors, including one that's an actual trap in the main entrance hall: It's even hooked up to a fake bust that spits out pictures, Polaroid style, of whomever it drops into the dungeon. Later, when Lupin sets fire to some stuff in the castle's basement, we can see smoke pouring out of all kinds of danged places, some of which seem to indicate the presence of even more chutes and trap doors.
 * Spoofed and used as a Running Gag in Excel Saga. Excel is "trapdoor'ed" almost constantly by her employer, Lord Il Palazzo, as punishment for being, well, herself. In one episode, the trap door is implemented as a form of transcontinental transportation.
 * Yes! Pretty Cure 5 uses this whenever the Nightmare Group wants to get rid of someone. They come back, though.
 * Used straight by Desler/Dessklok in Uchuu Senkan Yamato.
 * In Yu-Gi-Oh!, when Bandit Keith confronts Pegasus at gunpoint (in the dub, he merely points at Pegasus) in a last-ditch effort to get revenge. Pegasus nonchalantly opens a Trap Door that dumps Keith into the ocean. In the manga, he uses his MacGuffin to WELD THE GUN to Keith's hand, and have Keith shoot himself. (Keith in the anime, even in the original Japanese, survives the fall.)
 * Bleach anime #159. Trap doors open up under Renji Abarai and Dondochakka Bilstin, sending them into an arena where they confront the Espada Szayel Aporro Granz.
 * Hanaukyo Maid Tai La Verite. In episode 5 Ikyo Suzuki uses one to send Ryuuka down the garbage chute.

Comic Books

 * In Tintin in America, gangster Bobby Smiles presses a button with his foot to make Tintin fall through the floor and into a room with some Knockout Gas.
 * Later, when Tintin is being given a tour of a meatpacking plant, Smiles arranges for him to lean against a trick guardrail, in the hopes of turning him into Human Resources.
 * In King Ottokar's Sceptre, Tintin is involuntarily ejected from a private plane by the pilot opening a trap door underneath his seat.
 * Scrooge McDuck, of Disney ducks fame, has one of these in his office. He uses it quite often, be it to get rid of inconvenient salesmen or even of his own relatives.
 * Exactly where people end up changes between stories, or even within the story. On one occasion, the first person dropped landed outside on a mattress with a sign "And stay out!" next to it. The second landed in a bramble-bush. "I warned you!"
 * In one of the stories of The Life and Times of Scrooge McDuck Companion, Scrooge.
 * Wolverine: in the one-shot special "The Jungle Adventure"(written by Walt Simonson, pencilled by Mike Mignola), Wolverine falls through a trap-door while investigating a high-tech lab in the Savage Land, run by Apocalypse who provides the lampshade: "Greetings, Wolverine. You'll forgive me, but I'm required by law to say this, how nice of you to drop in so unexpectedly."

Fan Works

 * Andy and Sherman fall for this in Calvin and Hobbes: The Series.

Film
"Mook: I'm still alive, but I'm very badly burned."
 * Trapdoors appear in several Buster Keaton films, including "The Haunted House," "The Scarecrow," Sherlock, Jr.
 * Played with in Austin Powers: International Man of Mystery: During his introduction, Doctor Evil sends numerous minions into fiery pits with the push of a button, but when he reoccupies the Evil Lair thirty years later, the mechanisms are a bit rusty and the goon he incinerates is Not Quite Dead.
 * Although, same said henchman survived a fall off a cliff with two broken legs and a bear mauling him at the end credits, so you can't blame it on the mechanisms themselves.


 * The vampire superhero film Blade (1998) had a character named Dr. Karen Jensen fall down into a trap chute near the end of the film, where she found and killed her former research partner (who had been turned into a vampire slave), but climbed back out of the chute using an old bone for leverage.
 * Ringo Starr falls through at least two trapdoors in Help! One of them is in a pub and uses a beer glass (glued to its coaster) as a switch; fortunately for those trying to rescue Ringo, its seams are just visible. Another one is inside the area covered by an electrified cage somewhere in the Bahamas...
 * Used straight in the James Bond movie The Spy Who Loved Me where the villain had it set up in his elevator to drop into a Shark Pool. Bond defeated it by straddling the walls. In an earlier film, Diamonds Are Forever, Bond suspects the same trick, only to be felled by gas instead. Subverted in You Only Live Twice, when Japanese Secret Service chief—and Bond ally—Tiger Tanaka uses a Trap Door with slide to bring Bond to their first face to face meeting.
 * Star Wars VI: Return of the Jedi: Jabba the Hutt.
 * Kim Jong-Il had one in Team America: World Police. It's not outside the realms of possibility that this is Truth in Television. North Korea is that kind of country.
 * In Sinbad Of The Seven Seas, the titular Sinbad is dropped into a pit with snakes in it by Jaffar, the wizard of all that is evil. You know him, don't you?
 * In one segment of Disney's Mars and Beyond, the Martian leader pulls a rope and a trap door opens under the kidnapped heroine.
 * Labyrinth does this three times. First is when she gets past the guards with the riddle and says that the Labyrinth is "a piece of cake", the second is when Ludo is whisked right to the Bog of Eternal Stench, and then when Sarah gives Hoggle a kiss.
 * D.E.B.S. Lucy installs one inside a bank vault to bring Amy to her.
 * In The Man Called Flintstone, the Green Goose uses one on Barney Rubble.
 * At the end of Charade, the bad guy is killed off with one, on a theater stage with sections of floor designed to open with a switch.
 * Wild Wild West. Dr. Loveless has one installed on the command deck of his giant mechanical spider. He uses it to drop Jim West down to the engine deck for a "whuppin'".
 * Yellow Submarine. After they pass through the Sea of Science a creature drops into the sub. Ringo pushes a button and a door opens under the creature, dropping it out into the Sea of Monsters.
 * In Mickey, Donald, Goofy: The Three Musketeers, Pete drops a few of his minions down "The Pit", followed by the required scream fading out... only to subvert it when the short one stands up on the floor to reveal that it's roughly two feet deep. They are later seen playing poker inside and hop out when Pete needs them again.

Literature

 * L. Frank Baum used this trope a few times in his Oz books. For instance, Tik-Tok in Oz features a trapdoor used by the Big Bad over a hole so deep it goes to the other side of the world. Rinkitink in Oz contains a subversion, where the villain opens a trap door under one of the heroes, but, unknown to the villain, the hero has an artifact that protects him from harm, so he floats over the gap instead of falling through.
 * Ruth Plumly Thompson used trapdoors frequently in her continuation of the Oz series. One notable example is in The Silver Princess in Oz.
 * The Muppet Wizard of Oz has the Wizard use a trapdoor to send the heroes out of his throneroom. The Muppet characters all fall through, but Dorothy is standing in the wrong place, and has to be asked to jump.
 * Also used in the stage version of Wicked; saying more would spoil.
 * Used by Dickens in Oliver Twist. Mr and Mrs Bumble go to meet Monks in a derelict warehouse overhanging a river. After their conversation Monks reveals that they'd been sitting on a trapdoor over the millrace. "I could have let you down quietly enough when you were seated over it, if that had been my game." He didn't, but he'd clearly planned for the possibility.
 * In Robert E. Howard's "The Slithering Shadow," Conan the Barbarian runs from soldiers into a woman's room. She uses this on him.
 * In Live and Let Die, one of Mr. Big's men has a trap door in his fish warehouse over a shark enclosure that he gets Felix Leiter to fall through - later on, he does so himself in a fight with Bond. The basic elements of this scene are used in the movie Licence to Kill''.
 * In Who Cut the Cheese? by Mason Brown, this is part of how Duck and Cover barricade themselves in Cheeseless Depot D.

Live-Action TV
"Smart (picking the lock): "We'll be alright as long as this door isn't connected to a...to a..." 99: "To a what, Max?" They fall through a trapdoor, which drops them into two chairs directly in front of the villain. Smart: "Trapdoor." Villain: "Mr Smart, nice of you to..." Smart & Villain (simultaneously): "Drop in, yes...""
 * Spoofed in Doctor Who and the Curse of Fatal Death, when the Master accidentally falls down the same trap door three times. The journey back up takes three hundred and twelve years apiece, though he re-appears mere moments later due to Time Travel.
 * Get Smart: Affectionately parodied in a scene where Maxwell Smart and 99 are breaking into the villain's lair.

""Trap door? Is there a trap door?""
 * The Merchant Banker in Monty Python's Flying Circus gets rid of a charity collector this way (but keeps his collecting tin).
 * Used as the gimmick for the game show Russian Roulette, where contestants are eliminated by dropping through the door they're required to stand on (although, as the show's name suggests, whether or not a contestant is eliminated is a random process). To make the gimmick's usage even more Anvilicious, there's a lever to activate the Trap Door in front of each player, essentially forcing them to eliminate themselves in this manner.
 * And here I thought what made it Anvilicious was the fact that the platform was designed to look like the chamber of a revolver, with the six contestants as the "bullets".
 * One Saturday Night Live parody commercial was for a trap-door company. It began with scenes of malfunctioning trap-doors, complete with the voiceover, "Don't you hate it when this happens to you?"
 * Played straight in the second season The Man from U.N.C.L.E. episode "The Bat Cave Affair".
 * The Grand Master in M.I. High has one in his office for disposing of annoying underlings. It's not clear exactly what happens to those who fall through it, but the offscreen voice of one victim was heard complaining that it was uncomfortably warm in the cellar.
 * GSN's Russian Roulette. Guess what happens when someone pulls the lever and the Drop Zone light lands on yours?
 * The "Sock It To Me" bits on Rowan and Martin's Laugh-In frequently showed a character (usually Judy Carne) falling through a trap door.
 * Spoofed in this segment from That Mitchell and Webb Look where the architect working for the Evil Genius has built the trap door compliant to safety requirements. That is, with a red light, an announcement warning to clear the area, and yellow signs. The guy in the chair escapes.

Newspaper Comics

 * Dogbert has used a desk-activated Trap Door to dispose of at least one disgruntled employee.

Videogames

 * The use of a trap door goes all the way back to Interactive Fiction text adventures of the late 1970s and early 1980s, including Zork/Dungeon that slams behind the player if the step down through it.
 * Ryu Hayabusa is constantly punked by such pitfalls in the Ninja Gaiden games for the NES.
 * Both played straight and inverted in Chrono Trigger. First, Crono and team are dropped down at least one trap door. Later in the game, Crono and team are the ones who force a villain down a trapdoor (in his own lair, no less). This becomes a running gag, as the protagonists use this against the same villain again, and can use this against mooks at several points in the game.
 * In Les Manley in: Search for the King, the boss will drop you down a Trap Door if you try to steal the keys while he's watching, and you can Have a Nice Death.
 * The Mill levels in Donkey Kong Country 3 feature trapdoors which buckle open when jumped upon. Sometimes these are locked and the monkeys have to unlock them first before proceeding trough them.
 * Subverted by Leon Kennedy in Resident Evil 4 where the villain pulls this on him; if the player successfully Presses X To Not Die, he flings a Grappling Hook into the shaft wall to break his fall, stating that he "Won't fall for this old trick!" ...Leon, are you telling us that since Resident Evil 2 you've seriously fallen victim to this so many times that you've taken preventative measures?
 * The Sceptre of Lord British is being guarded by all three of the Shadowlords and a demon in their earthly fortress of Shadowkeep in Ultima V. Getting around that in bad enough. However, in addition, there are trap doors in the floor all around the sceptre itself; which leads to a lava pit and an instant Total Party Kill. If you're paying attention, you might notice the small dot in the floor that is usually only present for secret doors in the walls.
 * There's a Trap Door in Castle Oztroja that you'll find when playing Final Fantasy XI. It's right in front of a locked door that has a two switches in front of it. One opens the door, the other springs the trap. It changes randomly each game day. It's possible to hit the switch and run away before you fall down, but if you don't know that, this can be annoying(Or deadly, if you're low enough in level).
 * A variation of this is present in Overlord II, in which the Villain Protagonist proceeds to magically activate a hole underneath the Too Dumb to Live civilians who add unreasonable demands to their notifications of rebellions in his village (borrowing the Minions, becoming Mayor of a town of his, borrowing his mistress, taking his Evil Chancellor in as a pet) and dumps them into the sea of Lava at the bottom of his Netherworld.
 * In the SNES adaptation of Prince of Persia, Jaffar drops you down a trap door after the Boss Rush in the penultimate level.
 * In Paper Mario, this happens a couple of times.
 * The first time is in the Koopa Bros. Fortress. When you enter one room, you (the player, not Mario) see the trap door being installed under a question block. Yes, you have to hit it. It drops you into a dungeon where you meet your next party member...
 * That same party member comes in handy later, as a Bowser-face shaped door in Bowser's castle drops you into a dungeon the first time you try to go through.
 * Nethack. "A trap door opens up under you." Usually preceding some kind of death.
 * Tomb Raider is full of these, whether sprung by Lara's doing or her stumbling into them. The ladder usually has instant death traps such as spikes.
 * Becomes a Running Gag in Tales of Symphonia: If there is a trap door, you can be sure that Sheena will fall into it.
 * There's a number of these in a storage area in Metal Gear Solid. They're pressure-activated, and you can hear them buckle just before they open. If Snake's too slow to get off them, he dies.
 * In Final Fantasy VII, after the crossdressing incident, Don Corneo uses a trapdoor to dump Cloud and friends into the Midgar sewers.
 * In Tekken 5, Panda's ending involves her dropping a lackey down a trap door, followed by falling through herself when a friend gets curious about the Big Red Button.
 * Night Trap has this, and many other traps, and manipulating them is an essential part of the gameplay.
 * Double Switch. A number of the traps are essentially this, but some of them are a little more complex than that.
 * In Dwarf Fortress a mechanized floor hatch works like this, since it switches between states that count as "floor" and "open space". Which, of course, makes it useful for complex traps. Retractable bridge or floodgate can be used much the same way, but they have activation delay and cannot be used manually; horizontal bars and grates also can be used as delayed retractable floors - except, of course, they don't block sight or liquids.

Webcomics

 * Minions At Work: One way for your annual review to end.
 * The Last Days of Foxhound mocks the trapdoors found in the armory section of Metal Gear Solid by having Sniper Wolf fall into one - and barely hanging on, and the Mooks remarked that the only way they knew where the trapdoors were was because... "There used to be a lot more of us". It also mocks the other, stupidly impractical designs of the base.
 * Saturday Morning Breakfast Cereal: Why are there trap doors under our desks?
 * Used and parodied very often in Evil Inc., a corporation of old-style super villains. Here are a few examples from just the first 3 weeks of this comic.
 * What the Duck has one under a "selfie station" set up by photographers.

Western Animation
"Mr. Burns: Oh, it's doing that thing again."
 * Special mention goes to The Trap Door, which is basically this in reverse. Instead of the heroes falling in, the bad things come out.
 * Used plenty of times in Scooby Doo. Daphne had a talent for finding them and getting stuck at the bottom...
 * Used twice in American Dad when George W. Bush comes to their house for dinner. When Haley tries to confront him about his policies, Stan causes her to fall through a trapdoor. The second time, she puts her feet on the sides of the trapdoor, but then he widens the trapdoor with another button, causing her to fall in again.
 * There are two of them in The Emperors New Groove, both used to comedic effect. One apparently leads to a crocodile pit. The other leads to a random hole on the side of the palace.
 * Why do we even HAVE that lever?
 * What're the odds that trapdoor would lead me out here?
 * Spoofed in an episode of Family Guy, when Mayor Adam West tries to drop a protesting Peter through a trap door, except he's wider than the door and gets stuck. (The mayor apologises, "My malcontents are usually a lot skinnier.")
 * Common in Kim Possible; the first thing Shego does "in person" (after having appeared only in security footage) is walk into Drakken's lair, drop through a trapdoor into a waiting chair, and ask Drakken, "Ever considered a normal door?"
 * In another episode of Kim Possible features a gag where the bad guy used said devices on mooks that failed him. As the mooks begin to wise up and not sit in the rigged chair, he opens another door that the mooks were standing on. One instance even has said bad guy directing his mooks to the point before pressing the button.
 * On the Looney Tunes short "The Great Piggy Bank Robbery", Daffy (as detective Duck Twacy) finds the Gangster's Hideout and spots a welcome mat on the front door conveniently labeled "Trap Door".

 * Filmation
 * In the New Adventures of Batman, Batman and Robin are in a house owned by the Joker that has many trapdoors. They enter one room so equipped and Batman realizes that, although unaware of the exact danger, they have to exit the room now. As they race for a door, Joker starts opening trapdoors throughout the floor, but the Dynamic Duo manages to dodge them all. Unfortunately, the Joker is ready for that too, and suddenly the entire floor surface reveals itself to be a massive trapdoor itself and the Duo are captured.
 * Justice League episode "Bad Day on Black Mountain". After Mastermind teleports Superman to his lair, he activates a trap door under him and drops him into a cell lined with kryptonite.
 * Spoofed by Mr. Burns of The Simpsons often. Homer has, however, stood in the wrong position, or was too fat to fall into the hole, or it had been removed for safety violations, or it happened to be malfunctioning and making the victims fall back into the scene through the ceiling. (Although Lenny hasn't been as fortunate)
