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.
- One of Pepsi's Superbowl ads featured Elton John as a bored king who dropped various performers through a trap door in his throne room into the dungeon if they fail to entertain him. Naturally, the commercial ends with the king getting dropped through it himself by the ads hero, a singer played by X-Factor winner Melanie Amaro.
- A Skittles commercial has three people sitting on a rainbow. The moment one of them starts questioning if the rainbow they're sitting on even exists, the rainbow folds over beneath him, trap door style, causing him to fall.

- When Lupin pays Clarisse a visit, the Count's men subtly herd him to the room's trap door and drop him like a bad habit.
- More laughable is 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 — Poor Zenigata gets to be the film's demonstration. Lupin, thus informed, manages to turn it on Jodo and one of his guards. The Count is merely amused when he sees the picture of them nearly falling in and commends Jodo for confirming that the trap works.
- On top of those, when Lupin and Zenigata team up to escape from the castle dungeon, they start a large fire as a distraction; this works out beautifully when smoke starts pouring out of all kinds of danged places, many of which all but scream 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.

(Keith in the anime, even in the original Japanese, survives the fall.)

- 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!"
- According to Don Rosa, Scrooge's trapdoor drops people in a tank filled with skunk oil.

He decides he loves the future.

- Wonder Woman Vol 1: Tigra Tropica places an incapacitated Steve Trevor on a trap door above a cage full of tigers and sets things up so that if Wonder Woman attacks her Steve will be dropped as tiger food. Diana manages to lasso her and save Steve from the tiger pit, though as the fall woke him he was unsettled by the experience.
- In Violine, one appears at the front door of the mansion, leading to a Rube Goldberg Device for cleaning visitors. There is also one in the President's room, leading to a moat filled with crocodiles. A third one appears in Muller's Torture Cellar as part of his Death Trap.

- There are two of them in The Emperor's 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.
- In Robots: Ratchet tells his employees he doesn't wanna hear another word about former head of the company Bigweld.
Bigweld: (on TV) So remember: whether a bot is made up of old parts, new parts or spare parts, you can shine no matter what yo-Ratchet: My goodness. What a remarkable legacy. Concern for the common robot. You don't come across old-fashioned values like that anymore, friends. And for good reason. THERE'S NO MONEY IN IT! Hello? Memo to Bigweld! We're not a charity! That's why old Fat-Face no longer sits in the Big Chair. He's a relic! So, I don't wanna hear another "Where's Bigweld?" [imitates baby whining]
Loud-mouthed Chairman: We'll see him next month at the Bigweld Ball! He always goes to that!
(Ratchet presses a button on a remote; a trapdoor appears below the chairman and he falls into the hole)
- My Little Pony: Equestria Girls Rainbow Rocks: Right before the finals of the Battle of the Bands, Trixie and her two bandmates trap the Rainbooms under the stage by pulling a lever and opening a trap door right under their feet.
- 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.
Mook: I'm still alive, but I'm very badly burned.
- 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.
- Carnival Night: Ogurtsov the humorless killjoy tries to stop the New Year's show, striding onto the stage during a big musical number and attempting to call a halt to the proceedings.

- Havenhurst: There are plenty of trapdoors throughout the building, for dropping "evicted" tenants into the Torture Cellar.
- 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...
- James Bond:
- 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 Trapdoor with slide to bring Bond to their first face to face meeting.
- Star Wars VI: Return of the Jedi: Jabba the Hutt uses one to have Luke Skywalker drop in on his pet rancor. Unique in that you DO see that he's standing on some kind of grille, and earlier Jabba's minions made sure Luke was standing on the middle of it. C-3PO desperately tries to warn Luke about it, to no avail.
- 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, 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?
- Played with a couple of times in early Harold Lloyd short Ask Father. Harold is trying to get into his girlfriend's father's office to ask for her hand, but the father has some radical security measures. The first is a variation on this trope, a hidden conveyor belt that sends Harold zooming out of the office. Then when Harold gets back in a played-straight Trap Door sends him falling down a chute and out of the building into the alley.
- Willy Wonka & the Chocolate Factory: At the tail end of her "I Want" Song, Veruca is standing on a chute which has this effect.
- Theatre of Death: The stage in the theatre has a trap door that is use to take a spear thrust during the voodoo sketch to make it look as if the actress has been stabbed. Discussed during rehearsal, it becomes a Chekhov's Gun during the climax.
- In Shoot-Out at Medicine Bend, there is a trapdoor in Sanders' office concealing an old well. Sanders uses it as a trap in an attempt to dispose of Devlin, but it ends up being his henchman Walters who falls to his death instead.

- The Hitchhiker's Guide to the Galaxy.

- L. Frank Baum used this trope a few times in his Land of Oz.
- 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."

- In the K.J. Parker short story "I Met a Man Who Wasn't There", the narrating Villain Protagonist is a Boxed Crook police spy, and has a carpenter build a trap door built under the place in which a suspect sits, as a safety measure should a suspect try to attack him. Unfortunately, the first person he tries it on has magical powers including levitation.
- The levitation version is also used in Swellhead. In that case the hero deliberately sits on the trapdoor in order to shake the confidence of the villain.
- When Fandorin sits down to confront the Big Bad at the end of She Lover of Death, he notes that the heavy chair on a heavy rug that he sits down on won't move. That's because it's sitting on top of a Trap Door that the villain later triggers, sending Fandorin plunging into a death trap.
- Spoofed in Doctor Who: 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.
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)
Villain: Mr Smart, nice of you to...
Smart & Villain: (simultaneously) Drop in, yes...
- MacGyver (1985): In "Halloween Knights", Murdoc uses a trap door to drop Mac into a cage.
- Played straight in the second season The Man from U.N.C.L.E. episode "The Bat Cave Affair".

- The Merchant Banker in Monty Python's Flying Circus gets rid of a charity collector this way (but keeps his collecting tin).
- 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.
- 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 Trapdoor in front of each player, essentially forcing them to eliminate themselves in this manner. Another Anvilicious aspect 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?"
- A variant of this appeared on Survivor: Exile Island. It was an immunity challenge where each competitor knelt on a platform above the ocean. If they were unable to hold onto the ropes that held the weights, the trapdoor would open and drop them into the drink.
- Spoofed in a 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.
"Trap door? Is there a trap door?"
- In the Thunderbirds episode "Move and you're dead", Virgil paints a surrealist picture of Alan, who is less than amused. By way of retaliation, Alan presses a button which causes Virgil and Scott to descend rapidly through the floor.
- The Syfy game show Total Blackout uses trap doors in a slightly different way. After each round, the remaining contestants stand in front of trap doors and, on Jaleel White's command, are told to jump onto them. The contestant with the least amount of points in the round drops out of the game, while the other contestants' doors stay shut.
- On NBC's short-lived game show, Who's Still Standing?, one contestant (the "Hero") stands on a trap door on the center of the stage and faces off against a circle of 10 competitors also standing on trap doors (the "Strangers") in a series of trivia duels. Eliminated contestants drop 10 feet into a padded room below the stage. If the Hero decides to walk away at one point and keep their winnings, they have the option of either walking out of the studio or by dropping through the floor. And at the end of each episode, Ben Bailey (of Cash Cab fame), also drops through the Hero's trap door.
- In Dilbert, Dogbert recommends trap doors as a method of disposing of disgruntled employees who take advantage of "open door" policies. One strip shows him activating one from a desk, and another has him presenting one that drops the employee into rush-hour traffic to the Pointy-Haired Boss, who's dumb enough to fall into it himself.
- One The Far Side strip had a family visiting a store that sells trap-doors, and their son has just fallen through one of them, with the salesman assuring them the kid's safe in the maintenance department and ushering them onto the next model.
- Our Miss Brooks: In "Sneeky Peepers", Walter Denton installs a trap door next to a copy of Rodin's "The Kiss", mistakenly ordered for Madison High and covered with a tarp until it can be returned. Sneaking to take a peep, Mr. Conklin, Miss Brooks, Mr. Boynton, Mr. Stone and Walter Denton himself fall thought the trapdoor into a vacant (and locked) storage room in the basement
- Pit traps, with or without accompanying trap doors, are among the more popular traps in role playing games.
- Many theaters are equipped with one or more trapdoors in the stage to aid getting a character onto or off the stage without it being clear where they came from, and occasionally as a way to bring in set pieces. (Unsurprisingly, as these are designed to reliably function as floor when not in use, they tend to be neither remotely nor quickly openable.)
- Sweeney Todd: The Demon Barber of Fleet Street has a trap door built into the barber chair that often becomes a memorable part of every production. Allegedly the real Sweeney Todd used this as a method of killing rather than body disposal, as the victim would break their neck in the fall, which made less mess than a Slashed Throat.
- The Phantom of the Opera uses a fair number of trap doors - for the candle holders to rise up during the trip to the Phantom's lair, or for Raoul to fall through when he jumps from the bridge into the lake. Naturally, there have been accidents: Sierra Boggess and Sarah Brightman both had all of the trap doors opening onstage. Brightman stood very still and waited for rescue, Boggess fell down a door and was only held back thanks to her puffy dress (although the show had to be stopped so she could be taken to hospital because she hit the edge of the door and broke some teeth). Davis Gaines missed the trapdoor and broke his ankle, so Raoul was on his knees for the rest of the show.
- 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.
- In certain spaces of the Pachisi tracks in the versions of Dragon Quest III that feature them, ending your run then and there.
- 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 Trapdoor 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: Dixie Kong's Double Trouble! 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?
- In Ultima V, the Sceptre of Lord British is being guarded by all three of the Shadowlords and a demon in their earthly fortress of Shadowkeep. 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 Trapdoor 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. It's ineffective when used on Rose however due to the character's magical hovering.
- 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 latter 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.
- Used by you in Mastermind World Conquerer to dispose of your henchmen whose services are no longer needed.
- 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 Kuma down a trap door when he comes into her office, followed by falling through herself when Xiaoyu gets curious about the Big Red Button on Panda's desk.
- Similarly in Kuma's ending, Kuma does this to Heihachi, who has come to try and reclaim control of the Mishima Zaibatsu, only for Heihachi to somehow climb back up and press another button that opens a trapdoor underneath Kuma.
- 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.
- Several of these send Lan and the other net-battlers from the Netopia Castle meeting room into the dungeon in Mega Man Battle Network 2—And then another one on the roof for Princess Pride after KnightMan is beaten.
- Minecraft lets the player construct trapdoors out of either wood or iron; normally the wood versions are just doors that can be placed on floors or ceilings, but when hooked up to a Redstone signal they can function in the more traditional capacity.
- Pokémon Gold and Silver: The Ruins of Alph have these, triggered by completing each one of its puzzles and sending you inside the ruins proper.
- Super Mario 64: You have 8 Power Stars, so that you can open the first door with the big Star on it. Upon opening it, you run towards the painting with Princess Peach's face on it. Suddenly, it morphs into Bowser's face, and as you jump towards it, you run into an invisible wall... and just as you land, you start falling again. Bowser had installed a trapdoor to the Dark World in that very room anticipating you'd go for the painting in there!
Bowser: Bwa ha ha ha! You've stepped right into my trap, just as I knew you would! I warn you, "Friend", watch your step!
- The Legend of Heroes: Trails of Cold Steel has Class VII's first day of class all fall off a trap door and they must find their way out while working together.
- The Elder Scrolls V: Skyrim: one remote Dwemer ruin high in the mountains is just a single room with a pedestal in the middle. When you touch it, a security system fires up, scans you for a few moments, and then the floor below you flips over and dumps you down the longest single drop in the entire game. You land in some Soft Water, though, and have to fight your way through some caves to get back to the outside world.
- In Final Fantasy IV, when Cecil and the party try to reclaim the seven crystals after defeating Rubicante, they fall into a trap door, and their attempt has become moot, forcing them to escape. Edge later uses it to his advantage in The After Years when he and the Elban Four were out matched against the Mysterious Girl. He leads then into the exact same spot... and as it activates, the Eblan Four took time to register the trap door. Edge drops calmly, while they flail momentarily before falling.
- 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.
Liquid: Why... Why, why, why do we have trapdoors in our base? Is Doctor Doom our fucking architectural consultant?
- 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.
- Rusty and Co.:
- Subverted in The B-Movie Comic, where the trapdoor mentioned by Dutchman Fu is a complete fabrication meant to distract Snuka.
- Girl Genius: Unsurprisingly, Castle Heterodyne comes eqiupped with these, for disposing (or is that testing?) of any visiting heroes.
- Flander's Company: Hippolyte Kurtzmann has one in front of his desk in the "Super Pouvoir" music video, to get rid quickly of pesky supervillain candidates. Not seen in the series proper, though.
- Random Assault: Sometimes, a host will fall down a trap door and won't be able to get out until their internet or Skype works aga-I MEAN until they climb out.
- Burnie Burns had a Henckman Bros. model 607 trap door installed in his office in Downstairs that he'd use to drop employees into the restaurant on the floor below. He also has one in the ceiling in the same spot that drops a 16 ton anvil.
- In Adventures of Sonic the Hedgehog, Robotnik has used a few of these. Coconuts is a regular victim of one, sometimes multiple times in the same episode. The episode, "Boogey-Mania" had a mobile trap door with Hammerspace inside it.
- The Adventures of Young Gulliver episode "The Dark Sleep". One is used on Gulliver while he's in the witch's castle.
- 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.
- Defenders of the Earth includes an inversion of this trope. Monitor's security system includes a trap door which opens to reveal an energy mesh which instantly incinerates anything which touches it. This trap is first deployed onscreen when Ming takes control of Dynak-X and turns her against the Defenders. Mandrake nearly falls to his death when the rope he and three of his fellow Defenders are using to cross the pit over the energy mesh breaks, but Lothar pulls him up just in time.
- In the first opening sequence to Dennis the Menace, Dennis and Joey fall through a trap door in a fun house which sends them onto a mine cart ride.
- DuckTales (1987):
- In the first episode Scrooge uses one to cheer himself up:
Solicitor: Mr. McDuck, would you like to tip to the Retired Hand Hawkers of America?
Scrooge: No! (pushes button)
Solicitor: Ugh! (falls down while Scrooge laughs)
- The first time Scrooge met Fenton Crackshell, he dropped him down a trapdoor. Fenton's persistent, though.
- In the first episode Scrooge uses one to cheer himself up:
- 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.")
- 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.
- Futurama. Zapp Brannigan shows you don't need a Drop Ship to invade a planet.
Captain Zapp Brannigan: As you know, the key to victory is the element of surprise. [presses Big Red Button] Surprise!
[bay doors open under soldiers, dumping them onto the planet below.]
- G.I. Joe:
- "The Gamesmaster": Cobra Commander gets abducted this way.
- In one episode of the 1990 series, The Baroness orders Destro to prove his loyalty by dumping Zarana. He immediately pushes a button, and Zarana's bed turns out to be a trap door.
Destro: Baroness, consider her dumped.
- The Herculoids:
- "Sarko the Arkman". Used by the title character to capture Dorno, Tundro and Gleep.
- "The Antidote". The Spider Men ruler pushes a button to open one under Dorno.
- Naturally, Lucius uses one of these on Jimmy Two-Shoes. He uses it to get rid of Samy's stuff, but it only takes one glare for Samy to drop himself down.
- Jonny Quest episode "Dragons of Ashida". The title character has a servant pull a rope, which drops the floor out from under the Quest party.
- 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?"
- Another episode 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". Daff catches on immediately, steps to one side of the door and rings the bell, when a trap door opens up underneath him and sends him to the basement.
- In "The Jet Cage," this is how Tweety uses the hatch on his flying birdcage to dispose of Sylvester when it returns to flight.
- In the always unintentionally awesome Mister T cartoon, there was an episode where a big New York Chinese restaurant has one of these near the door, with a big lever by the cash register. Naturally, it's there so that at one point it can swallow up our heroes as they try to flee, but you really have to wonder why it's there. To echo the Agony Booth recap, do they have that big a problem with customers who dine and dash? (Check it out here.) Also, it opens on a hundred-foot drop into a warehouse full of stolen merchandise, which ... makes you wonder about the thinking behind this particular criminal syndicate. Not to mention the architecture of New York's Chinatown restaurants.
- In the My Little Pony: Friendship Is Magic episode "Castle Mane-ia", the Castle of the Royal Pony Sisters has trap doors which are activated by pressing a pipe organ's keys.
- An old Popeye cartoon "The Dance Contest" has judge Wimpy dropping couples through trap doors if they're not good enough - or if they don't have any mustard handy.
- Samson & Goliath episode "Operation Peril". After Samson and Goliath reach the ship's control room, the Big Bad pushes a button and the floor slides open underneath them and they fall into a containment area.
- Used plenty of times in Scooby-Doo. Daphne had a talent for finding them and getting stuck at the bottom...
- She-Ra: Princess of Power:
- Hordak had one to drop his hordsmen into. On the rare occasion one of them would avoid it, another trap would get them, some of which were far less pleasant. The mooks couldn't see it, since the whole throne room was paved in squares, and the danger spot was also the most respectful place to stand.
- At one point, Mantenna jumped off the trapdoor to the side. The neighboring tile tipped up and slid him down into the hole anyway.
- The Simpsons: Mr. Burns has a trapdoor in his office, which he uses to get rid of anyone who bugs him. It's been spoofed a number of ways over the years, including Homer getting stuck due to his weight, or standing in the wrong position (and jumping down the hole when Burns asks him to), or the trap having been removed for safety violations. In one memorable instance when the kids of Springfield Elementary came asking for donations, Burns dumped them out...only for them to fall back into the room through the ceiling.
Mr. Burns: Oh, it's doing that thing again!
- Then there's the Buzz Cola Trap Door: Fall into the flavor hole!
- Star Wars: The Clone Wars, "Lair of Grievous": Once Grievous gets to his control center he opens a trap door underneath the heroes that sends one of the clone troopers to a fiery death and nearly results in Commander Fil's death, though he and the Jedi react quickly enough to save him from the lava pit the door leads to.
- Star Wars Resistance:
- Short "When Thieves Drop By" reveals that Flix and Orka have a trapdoor installed at the front of their shop, the Office of Acquisitions, for the purposes of dropping would-be thieves down it. Brothers and criminals Narb and Nod both separately fall victim to it.
- "Descent": When Kaz, Yeager, Neeku and CB-23 are cornered by stormtroopers in the maintenance tunnels, they get rescued when the Chelidae, alerted to their predicament, open up a trapdoor they're standing on.
- One episode used a version of the above New Adventures of Batman trick, with the Riddler setting the trap. The Dynamic Duo find themselves in a room with a plainly-visible trap-door built into the floor, and just as Batman comments how obvious the trap is, the entire floor except the "door" falls away.
- In "The Fairy Tale of Doom", several members of the Legion of Doom trap Black Vulcan, Green Lantern, Batman, and Robin in a trap door even though 1)two of them can fly and the other two carry grapple ropes as standard equipment and 2)they're in the Hall of Justice and ought to know where the trap doors are.
- In the 1940s Fleischer & Famous Superman cartoons, Superman couldn't fly yet and wound up dropped down a trapdoor in one episode. Of course, he was still stronger then a locomotive and able to leap tall buildings in a single bound...
- Special mention goes to The Trap Door, which is basically this in reverse. Instead of the heroes falling in, the bad things come out.
- The Technodrome in Teenage Mutant Ninja Turtles (1987) has a circular, pizza-like one in the main control room. In one episode, Leonardo activates it with a control panel when Bebop and Rocksteady are standing on it.
- In Visionaries, Darkstorm has several lever-operated trap doors in his throne room. However, the episode "Honor Among Thieves" sees him (courtesy of Ectar) fall into one of these traps.
- Parodied in Harley Quinn (2019) when the Joker is supervising the construction of his Supervillain Lair and Reality Ensues.
Joker: I need a permit for a trapdoor? The whole point is no-one is supposed to know about it! Especially the City!
- In the 19th century practice of "Shanghaiing" (kidnapping people to serve as sailors), one method of doing this was to trick people into standing on a trapdoor in a bar, sometimes lured there by a pretty woman; the trapdoor would then open, so they would fall into the basement below. This happened in Portland, Oregon.
