The End - or Is It?

An Ending Trope when the closing of the show reveals that the villain, monster or other major threat is still out there, creating doubt as to whether or not the heroes have achieved a final victory.

This is usually a type of Sequel Hook, and often done as The Stinger. See also Eye Awaken, Finger-Twitching Revival, and Not Quite Dead.

Compare Or Was It a Dream?, Real After All, and Schrodinger's Butterfly.

Anime and Manga

 * The ending of Noir:
 * Monster.
 * The ending of the manga Oldboy strongly implies that there are still unresolved plot issues.
 * Code Geass -- It depends on what the audience makes of the scene and the existing pieces of Word of God.  The fans are, generally speaking, split in half over the issue.
 * Sometimes, even the titular teacher in Hell Teacher Nube is unable to put a permanent end to the Monster of the Week -- the best he can do is save his students from the threat, or it escapes before he can exorcise it. The series balances this out with frequent Aesops about not trusting that mysterious salesman with the shifty grin, or not talking to strangers (especially if they look suspicious or appear out of nowhere in the middle of the night,) or staying the hell away from the masked killer with the Sinister Scythe.
 * Shaman King. At the end of Kang Zeng Bang, we see

Comic Books

 * In the Groo the Wanderer story "The Aranja", Groo and Chakaal are hired to kill a giant spider that is terrorizing a village. Stumbling drunkenly around the spider's cave, Groo notices something he figures is important and tries to tell Chakaal, who is unfortunately too busy to listen. Soon after, Groo has forgotten the whole thing. As the heroes depart at the end of the story, the readers are shown what Groo discovered: The aranja was a female, and it had laid several eggs, which are just starting to hatch...
 * Watchmen closes on a shot of Rorschach's journal in the office of the New Frontiersman, implying that . A rare example of where a sequel was not planned, although given the nature of the comics industry lately, it's possible one may be made eventually anyway despite Moore's wishes.

Film
"Servo: And His Eyes Open. Crow: An-n-n-nd his eyes open. Mike: His eyes open. Servo: Eyes open. Crow: Eyes open. Mike: His EYES open. Crow: Come ON! Servo: Man!"
 * From the Alien series:
 * Alien leaves open the possibility that the cat that Ripley takes along with her as she flees the soon-to-be-nuked ship has been infected. This is, of course, proven untrue in the second film, and quickly takes a back seat to the fact that the title monster stowed away on Ripley's escape pod. There was also an original Twist Ending planned:
 * After the credits of Aliens there is silence and a dark screen. Then the organic squelch of an egg opening can be heard...
 * The last shot in the remake of Ocean's Eleven shows Ocean, free from jail and reunited with his girl, driving past the camera and seemingly off into the sunset, but after a fairly long delay, we are passed by another car which seems to be following them, driven by two mooks of the Big Bad.
 * Actually, if you listen to the dialogue between Danny and Rusty as they approach the car, it is implied that they already know they're being followed and will lose their tail shortly afterwards. At least until the Ocean's 12.
 * Occurs at the end of the film Space Mutiny, notable only because of the commentary when it became an episode of Mystery Science Theater 3000. A slow, meandering shot of the villainous Kalgan's body, and...:

"Crow: Ending conceived and written by a tube worm. Mike: C'mon, dead people know what's going to happen!"
 * A very similar example occurs in another Mystery Science Theater 3000 episode, Werewolf, in which the movie's final scene takes its own sweet time in revealing that the Love Interest of the werewolf is now also a werewolf, again much to the impatience of Mike and the 'bots.


 * They would see the incredibly similar It Lives by Night the following season, with the ending being just about exactly the same (the only tangible differences are that the guy is married to the woman and is a bat man).
 * The Blood Waters of Dr. Z also had a similar ending, with the woman he tried to turn into a fish monster following the escaping monster into the sea.
 * Yet another notable Mystery Science Theater 3000 example: the film Danger Diabolik It ends with the titular Heroic Sociopath encased in gold and his love interest being carted off to jail. Diabolik manages to sneak a wink at his girlfriend to show her that he's still alive and she shoots him a knowing look back as she's being led away, thus implying that she'll do something to rescue him. The film doesn't elaborate what though, and the ending shot with Diabolik's laughter filling the cave despite him being in what is most certainly a hopeless Fate Worse Than Death situation borders on Narm.
 * Happens quite famously at the end of the first Friday the 13 th film and most subsequent ones, insinuating that the threat is not in fact over.
 * Humorously, the first one was just meant to be a final scare, not a Sequel Hook. Obviously, it's become one with all the other movies.
 * The film version of the musical Little Shop of Horrors had an Audrey II cutting growing in the garden of Seymour and Audrey's house. (Actually, this ending was a replacement for the original Downer Ending, which test audiences disliked.)
 * Used at the end of Big Trouble in Little China. (What is it with Asian villains and this?)
 * Employee Of The Month did this about seven times. Yes, seven.
 * Skeletor is revealed to be alive at the end of the film Masters of the Universe, setting up a sequel that never happened because the movie bombed.
 * Subverted in Bats, where the closing scene shows the lone surviving bats slowly and menacingly rise up from the dirt in preparation to fly off into the sunrise, only to get run over by the heroes' SUV as they drive off into the sunrise.
 * The ending of Legend has a shot of Darkness (who was apparently destroyed) laughing.
 * Manos: The Hands of Fate: "The End?" Also, Torgo escaped, albeit missing a hand.
 * At the end of the movie adaptation of Christine, the metal cube that was once an evil car sits there... and one little corner bends.
 * The original novel also hinted that the cube still had some life in it in the "first" ending, then proceeded to make it very clear that Christine was back in the epilogue.
 * The 90's comedy Nothing but Trouble ends with one of these.
 * The Lost Skeleton of Cadavra, as an Affectionate Parody of black and white B-grade '50s sci-fi flicks, naturally ends with a bold white THE END, after which appears a question mark, in turn followed by the inevitable OR IS IT? and some Fauxlosophic Narration in the same intentionally bad dialogue style as the rest of the movie.
 * And it just so happens that they are making a The Lost Skeleton of Cadavra 2!
 * Just before the credits roll in X Men: The Last Stand
 * The ending of the American remake of The Ring indicates that, yes, she figured out how to not be killed by the ghost girl, but,
 * The original book has an even more drastic version:
 * And the Japanese movie adaption ends by saying how they'll continue to spread the curse from one person to another, over and over.
 * The remake of The Hills Have Eyes and its sequel. In the first one, the survivors have a group hug as the camera pulls out and reveals that what is presumably another mutant watching them through binoculars. For the sequel, the survivors limp away as the camera pulls out and reveals that what is presumably another mutant is watching them on a laptop that has a long-range heat-sensitive camera.
 * Used famously at the end of Flash Gordon.
 * The movie version of The League of Extraordinary Gentlemen does this for
 * The Super Mario Bros. Movie ends just after Daisy has returned to her homeworld and the two parallel universes are closed off forever... with Daisy walking in holding a gun and dressed like a soldier saying "Mario, Luigi, you're not going to believe this..." We never found out what she meant, which may or may not have been a good thing.
 * This rather extreme kind of sequel-trigger rarely seems to be picked up, although Mortal Kombat was an exception.
 * Back to The Future: It's your kids, Marty! Something's got to be done about your kids!"
 * They didn't even originally intend that to be a real sequel hook or even a real cliffhanger. It was only tongue-in-cheek at first, and the "TO BE CONTINUED" sign wasn't superimposed over the screen until the film was out on video after a sequel was already in the works.
 * Played straight in part II; however, it may or may not count as part II and III were made pretty much together, going as far as showing a trailer for part III at the end of part II.
 * The ending of Godzilla Mothra King Ghidorah Giant Monsters All Out Attack shows that
 * The "new" American remake of Godzilla ends with an egg surviving, after all the effort to kill them.
 * During the end credits of the 2007 Transformers live-action movie, Starscream (who escaped the F-22 Raptors in pursuit because they had bigger fish to fry) flies out of Earth's atmosphere and shoots straight up, presumably returning to Cybertron for reinforcements.
 * In the (original version of the) horror movie The She Creature, a hypnotist uses a woman in a trance to summon an aquatic monster from beyond time. After being mortally wounded by it, he banishes it forever. But the final shot of the movie shows the ocean, and a big "?" over it.
 * The original version of Godzilla vs. Hedorah ended like this as well. Of course, Yoshimitsu Banno was practically exiled from the studio after its completion, so...
 * Bullshot (1983). The villain is supposedly killed when his plane runs out of fuel, though they Never Found the Body. The movie then concludes with a montage of photos showing the wedding of the hero and the heroine; the last photo shows the villain disguised as their chauffeur. But all that is another story.
 * In the Fu Manchu movies starring Christopher Lee, after his evil plan was foiled, he would say "The world shall hear from me again."
 * In Out of Sight, gentleman bank-robber Jack Foley and straight-arrow federal agent Karen Sisco have an affair, despite the fact that she's supposed to put him in jail. At the very end of the movie, after
 * Halloween: Michael Myers is shot repeatedly and then falls out of a window. But when Loomis goes to look, the body is gone. Turns out he really was the Boogeyman. And the parade of increasingly crappy sequels begins...
 * "I shot him six times!!"
 * He actually shot him *seven* times, as anyone can plainly see. But in the heat of the moment, Loomis was probably focusing more on aiming and firing than on keeping count of the bullets, so it's not an unusual flib for the character to make.
 * In the original movie, Loomis did only shoot Michael 6 times. For some reason, the flashback in the sequel showed him shooting Michael 7 times... despite the gun only being a 6 chamber revolver.
 * In the Street Fighter movie, M. Bison lives, but Raul Julia less so.
 * Catwoman in Batman Returns.
 * Con Air's Garland Greene escaped. But apparently is just trying to earn some bucks.
 * The obscure blaxploitation film The Black Six ends with a Crowning Moment of Or Is It? Awesomeness - we see still frames of the title characters, then the caption "HONKY LOOK OUT! HASSLE A BROTHER AND THE BLACK SIX WILL RETURN!!!"
 * Fantastic Four; to no one's surprise, as the crate carrying von Doom's remains is shown departing, there's a hint of life.
 * While this trope debuted in the 1950s version of The Thing from Another World, the 1980s version (simply titled The Thing) featured a less direct version of the trope. In the end,
 * The original 1958 version of The Blob, as seen at the end of this clip.
 * Combined with Oh Crap at the conclusion of 2010's The Wolf Man, as the film ends with the police detective clutching his bite-wounds and realizing he's been infected with lycanthropy too.
 * How could one forget Event Horizon, with the door closing at the end... automatically, because no one's standing near it. Right?
 * Black Swan: On a similarly disturbing level as Shutter Island.
 * The Wizard of Gore: After a series of Shocking Swerves, the movie ends with a textbook "The End... Or Is It?" card.
 * Just like the comic, Kick-Ass ends revealing Red Mist has gone evil for good and is now a super-villain planning revenge.
 * At the end of Dracula 2000, just before the sunlight takes him, Dracula turns Mary back into a human (luckily, after she falls from the roof). The ending voice-over reveals that Simon and her have become the protectors of the vampire's ashes. The final shot is a close-up of Mary's eyes, which suddenly turn an inhuman color.
 * Final Fantasy VII: Advent Children. "I will... never be a memory...."
 * Most people know the ending of Carrie: . The ending of the made-for-TV 2002 remake is notably different, though. . While the endings in the both the book and the movie are final yet creepy (and perhaps the book has a touch of Or Is It? thrown in for good measure), this version implies that the horror is not over.
 * Played with in Teenage Mutant Ninja Turtles II, Super Shredder is crushed underneath a collapsing dock, The Turtles recover from the collapse, and THEN A HAND SHOOTS UP OUT OF THE RUBBLE! "No one could have survived that!". Then the arm drops with a groan. He's done for. Granted, there is a sequel, but it is not based on the ending of II.
 * Most of the A Nightmare on Elm Street films end this way.
 * Rise of the Planet of the Apes ends with the revelation that
 * Sherlock Holmes: A Game Of Shadows ends with the question-mark variation
 * Batman: The Movie: After the Freaky Friday Flip that seems to defy the Status Quo Is God, Batman and Robin going out inconspicuously throught the window. Then we see The End superimposed in the screen. A second later, they add the word living and a question mark: The Living End?
 * After the title homicidal orangutan of Link dies, the heroine and her boyfriend pick up one of the friendlier chimps in their car. The camera then pans out to reveal the field behind them is full of dead sheep, showing us that the chimp is homicidal too.
 * There are only ever two endings for Filipino Horror movies: a Cruel Twist Ending (especially in the Shake Rattle And Roll series of anthology films), and this. Either way, it's mandatory. No exceptions.
 * The trailers for Tim Burton's Frankenweenie end with "THE END... OR IS IT".
 * The trailers for Tim Burton's Frankenweenie end with "THE END... OR IS IT".

Live Action TV

 * In Monster of the Week episodes of The X-Files, the show often closed on a shot of the creature under a bed, or the supposedly dead creature opening its eyes, or even a disassembled computer lighting up.
 * Doctor Who homaged this at the end of the third series of Doctor Who, which ended with
 * And a season or so down the road,
 * Meant to have happened at the end of Davros's debut story "Genesis of the Daleks" to show Davros's life support system still on. However, this detail got left out in production.
 * The Second Doctor's debut episode, "The Power of the Daleks", ends with the TARDIS fading out next to the crushed remains of a Dalek... and as it does so, the eyestalk rises to watch it disappear.
 * The next Dalek story, "The Evil of the Daleks", was meant to see the Daleks Killed Off for Real, but at the last minute the production team were instructed to show some indication that some Daleks had survived. Unfortunately, since the last episode no longer exists, accounts differ as to what it was.
 * After the Fourth Doctor, he looks up to his current companions and grins, stating It's quite a moving moment considering that it's made to look like he may not be coming back at all.
 * At the end of sixth Doctor series "The Trial of a Time Lord", the Doctor has overcome all the Valeyard's convoluted plans, and seems to have defeated him, only for
 * At the end of the Red Dwarf episode "Polymorph", we see that the pod containing the titular shape-shifting monster actually contained two of them. We then see the crew walk past a corridor with two Listers in tow.
 * The remastered version has a Revised Ending, with a caption stating that the second polymorph concealed itself in Lister's clean underwear drawer, where it died of starvation many years later.
 * Used in a number of Buffy the Vampire Slayer episodes, especially in the early years, which left a lot of What Happened to the Mouse? in its wake.
 * The 2nd season Star Trek: Enterprise episode "Dead Stop" involving an unmanned space station that repairs ships, secretly abducting their crewmembers and using their brains to augment its abilities. Apparently destroyed, it is seen at the end to be reassembling itself.
 * Star Trek: Voyager. "Bride of Chaotica" (which takes place in the Captain Proton holoprogram) concludes with Dr. Chaotica dying, whereupon music plays on an imagizer and the words THE END appear... followed by a question mark and Chaotica's Evil Laugh.
 * Played more seriously in the two-parter "Year of Hell", about a scientist who creates a ship that can alter time itself, creating all kinds of hell for himself, countless civilisations, and Voyager. After the vessel is destroyed, history gets a Reset Button back to 'normal' and we see the scientist in a happy moment at home with his wife (who'd previously been wiped from existence). The camera finishes on a shot of scientist's table, on which lie the plans for the timeship.
 * An episode of Airwolf involved the titular helicopter's designer programming a doomsday failsafe into its main computer, which was supposed to electronically trick the United States and Russia into launching their nuclear arsenals at each other. While the heroes and the special guest heroine (who happened to be a computer expert and "usually beat" Airwolf's creator at chess) were able to regain control and prevent a nuclear war, the light-up key that had initiated the whole thing flickered fitfully just before the closing credits, implying that it could all start over again if the heroes weren't careful.
 * Parodied in an episode of Everybody Loves Raymond, in which Ray is home alone for the weekend and Robert teases him about it, before adding "Or ARE you?"
 * The season 1 finale of Heroes, which builds up to the final defeat and killing of Sylar, shows signs he's potentially alive (which it turns out he is for season 2, albeit somehow weakened).
 * Building up to a Downer Ending that evokes this trope is the whole point to the fake-cryptid-footage show Lost Tapes.
 * In Power Rangers RPM, the Rangers defeat Venjix and Earth is restored. The last shot of the series is the rangers' morphers,, being locked away.
 * The Criminal Minds episode "Bloodline" ends with the mother of the evil Roma family telling her son "Don't tell them about your brothers". After the team translates what she said, it cuts to a scene involving a family similar to the captured one, getting ready to kill a couple and abduct a girl to be their son's bride.
 * Later episode "Solitary Man" has one of the team mention on the ride home the number of "highway serial killers" active in the country at any given time. It then cuts to a dark highway, where a lone hitchhiker is picked up by a truck identical to the one used by the (now dead) killer featured in the episode.
 * In the Supernatural episode Tall Tales, after Sam, Dean, and Bobby leave, the body of the Trickster they'd just staked through the stomach disappears. Turns out it was only an illusion the real Trickster created.
 * Another episode called Monster Movie is filmed to resemble any of several old horror movies. The end card is "The End...", with a question mark appearing after a moment.
 * At the end of the Season Five finale, Dean has gone to live with his old flame and is trying to settle down to life without Sam. Pan back from Dean at the dinner table with Lisa and Ben, to see  standing under a streetlight, watching.
 * "So, that's all for this hypothetical edition of QI... Or Is It? Yes, it is. Goodnight."
 * Batman: The Movie: After the Freaky Friday Flip that seems to defy the Status Quo Is God, Batman and Robin going out inconspicuously throught the window. Then we see The End superimposed in the screen. A second later, they add the word living and a question mark: The Living End?

Literature
"Happy ending? [Owens] frowned at the intonation in his mind that had put a question mark after those two words. Happy ending! he thought grimly, but the intonation slithered out of control so that it became Happy ending? again."
 * The Gun, a short story by Philip K. Dick. A spacecraft investigating a planet destroyed by nuclear war is shot down by a robot anti-aircraft weapon. Fortunately they're able to approach the weapon on foot and deactivate it, then repair their spacecraft and take off. They plan to return later and remove the contents of the archive that the gun was protecting, unaware that underground robot repair units have already been sent to put the gun back together again.
 * In the Gaunt's Ghosts novel Only in Death, Hinzerhaus appears to be haunted at first. Gradually, various explanations - not all scientific - are given, until it seems that the phenomena have been explained away. The very last part of the novel, excluding Hark's final diary entry, then suggests that maybe the fortress is really haunted after all.
 * The book of Wicked seems to suggest, with it's last lines, that the main character may have survived her encounter with Dorthy on some level, or at least may be coming back.
 * Isaac Asimov actually managed to fit one of these into the first chapter of his novel of Fantastic Voyage. The characters are hoping a Soviet scientist's defection will turn out well:
 * Isaac Asimov actually managed to fit one of these into the first chapter of his novel of Fantastic Voyage. The characters are hoping a Soviet scientist's defection will turn out well:


 * Every single Goosebumps book ends with one of these. The last few lines of each book usually reveal that one of the monsters is still out there, that something is still stalking the protagonists, that the safety they thought they gained is probably an illusion, the person they rescued isn't actually safe, or that whatever victory over the monsters they achieved is probably not real. Or might not be real. It's sometimes ambiguous, but not in the "Was it all just a dream?" sense.
 * The Stand by Stephen King has a epilogue which shows that.

Music

 * The music video for Michael Jackson's "Thriller" has Jackson turning into a zombie, summoning his dancing zombie pals, and surrounding his girlfriend in an abandoned building. She then wakes up next to un-zombie Michael Jackson, who looks at the camera revealing werewolf eyes at the very end.
 * In introducing a performance on Britain's Top of the Pops music program, the announcer said before the video played, "These two never actually sung on the record, so here's Milli Vanilli, 'Girl You Know It's True', or is it?"

Radio

 * Final Fantasy Tactics Advance's Ivalice was supposed to vanish, right? Well, in its Radio Drama, after the supposed ending in the game ends, the music stops, and a voice from Montblanc says towards Marche that he wanted to meet again in the dream. May it be that the dream Ivalice is still there or that it was Montblanc's Final Speech is still a mystery.

Video Games
"Jackie: Am I dreaming? Jenny: Yes. You have to wake up."
 * At the end of Batman: Arkham Asylum, one of three villains will.
 * A common video game use of The End, Or Is It? is to punish the player for not getting One Hundred Percent Completion: without every MacGuffin recovered, the true villain isn't fully defeated and is alluded to in the end credits (such as in the Kirby games).
 * The extra endings in Chrono Trigger (obtained by defeating Lavos after only completing certain chapters) are chock-full of these.In a particular case, Frog proceeds to face Magus alone, there is a cut to the credits just as the two are clashing, battle noises are heard throughout the credit roll, and in the end a caped silhouette, who might be Frog as well as Magus, stands victorious above Magus' Keep.
 * Especially the Chaos Emeralds from the Sonic the Hedgehog series. At least the old ones where you actually had to collect them yourself.
 * Though sometimes it's the other way around, and the player's imperfect completion allows them to finish the game with a 'and that's simply the end of the villain' vibe. If the player were to push things, the conspiracy would unwind and further troubles would ensue.
 * True Crime: Streets of LA does this transparently; the conclusive ending isn't available until following false leads to three Or Is It? endings.
 * Another common use is to have everything neatly wrapped up after the main game, and throw that in to doubt upon getting One Hundred Percent Completion, as a Sequel Hook.
 * The last thing we see in Beyond Good and Evil, after the credits have rolled, is
 * Condemned: Criminal Origins ends with a particularly cryptic instance of this.
 * The sequel Condemned 2: Bloodshot also ends ominously.
 * Dead Space ends
 * In In Famous 2,
 * In Nine Hours, Nine Persons, Nine Doors, three endings do this.
 * F.E.A.R and F.E.A.R Perseus Mandate both have this trope after the credits, though it is noticeably absent from Extraction Point. In the first game, there is In Perseus Mandate,
 * Seen at the end of the game Gears of War.
 * Halo 3 has a variation where
 * In the extended finale available only when beating the game at the hardest difficulty, the wreckage is shown
 * House of the Dead. Both villains are most definitely dead and they're still making plans.
 * Limbo of the Lost uses these exact words in its ending, showing Fate and Destiny about to throw down again with a new human pawn, promising a sequel to pick up where the game leaves off. Considering how the game itself turned out, a sequel seems unlikely at this point.
 * Metal Gear Solid 1: MGS2:  MGS3:  MGS: Portable Ops:
 * Each of the Metroid Prime games had one of these as its best ending. In the first game, In the second game,  In the third game,
 * The MOTHER series LOVES this trope.
 * After the credits roll at the end of the original Mother, there's a shot of a mysterious man at a telephone, mentioning that "something new has come up". Which leads us to...
 * Earthbound's post-credits epilogue had Ness awakened by knocks at the front door, just like at the beginning of the game -- but it's Picky at the door and not Porky, there to tell Ness that he has a note from his brother, proclaiming "Come and get me, loser!"
 * And finally, Mother 3's ending sees
 * Well, dialogue from the Magypsies and even the Big Bad suggests that
 * Oddworld: Stranger's Wrath features this trope, in addition to a double Tomato Surprise, when Sadly, Oddworld Inhabitants dropped out of the video game business after this game, but they're on their way back.
 * Overlord.
 * This is followed up on in the Expansion Pack, Raising Hell, where, but as for a full explanation, we'll just have to hope the sequel or one of the spinoffs provides it.
 * The sequel has one, with Gnarl noting that the Overlord may soon be brought down by many threats to his power.
 * In Portal
 * Word of God says that Chell escapes, "injured enough to pass out" but alive.
 * In fact, Valve has released an update that makes it perfectly clear that there WILL be a sequel. Among other (many other) things, the end game
 * Portal 2
 * Congratulations! You've completed the Portal 2 multiplayer co-op campaign! You and your little robot avatar buddy should be very proud that you solved all those devious plots, and secured that completely worthless information that looked possibly like either a way for the GLADOS AI to escape or schematics for a Kill Sat.
 * Psi-Ops: The Mindgate Conspiracy ends with Nick
 * In the credits sequence for Rayman 2: The Great Escape, . Similarly, at the end of Rayman 3: Hoodlum Havoc,.
 * Secret of Evermore ends with the Big Bad in his unaltered form chuckling with the words "The End?" A Sequel was never made.
 * The first Sly Cooper game showed one of Clockwerk's eyes lighting up on his disembodied head.
 * Somewhat subverted, since the second game reveals that
 * In Spyro: Year of The Dragon, the sorceress's hand rises out of the lava after the final boss fight. However, if the player gets the one hundred percent complete (collect all the dragon eggs and gems), she can be killed for good.
 * In Star Fox 64, if you reach the planet Venom the easy way, you see Andross's face laughing as the team ventures off towards the sunset. If you reach it the hard way, defeating the real Andross in the process rather than a robotic duplicate, you just see a banner saying "THE END". Either way, he turns out to be still alive in Star Fox Adventures. Sadly removed in the 3DS remake.
 * In Sweet Home, if one gets the perfect ending (all five party members alive), the five characters are seen together, happy. As the ending closes, a face turns around and reveals that it's a monster!
 * Wonder Boy in Monster World ends with the words The End on a starry background, then suddenly the boss music plays and the Big Bad flies over the text, changing it to To Be Continued. He then winks and disappears.
 * Tenchu 2.
 * The next-gen Bionic Commando has two for the price of one.
 * Played for laughs in a fan-made Frozen Throne campaign, which is supposed to be an unofficial alternate sequel to the original campaign.
 * Wizardry 4. "You wonder if there was something you missed..." The best ending follows up with "then you realize there isn't".
 * A Tale of Two Kingdoms, for every ending except for the best one (mostly because you left the assassin on the loose...)
 * King's Quest III, in obvious sequel bait.
 * System Shock starts with the "hero", a nameless hacker, breaking into the Trioptimum computer system. He gets caught, but escapes jail by unfettering an AI for a corrupt executive. All hell breaks loose as the AI creates a horde of mutants and cyborgs. On completing the game, the hacker refuses all reward and instead goes back to his computer... Only to break into a fresh network and discover yet more genetic experiments going on elsewhere.
 * The sequel, set some time after the first game, has a new hero defeating the same AI once again on a space cruiser. However, the end reveals that.
 * The original Ecco the Dolphin ends with a dolphin asking you if you think that the alien race you just defeated is truly destroyed.
 * The Ending Sequence of Wing Commander 2: Special Operations 2 has that Evil Laugh... (and, of course, the message "To be concluded in Wing Commander III" after the credits...)
 * The Darkness puts a twist on this by having a sequence that suggests that the complete defeat of the hero at the hands of his Enemy Within might not be all it seems. Shortly before he's seemingly overtaken by The Darkness, a conversation between Jackie and Jenny ends with the odd exchange:
 * The Ending Sequence of Wing Commander 2: Special Operations 2 has that Evil Laugh... (and, of course, the message "To be concluded in Wing Commander III" after the credits...)
 * The Darkness puts a twist on this by having a sequence that suggests that the complete defeat of the hero at the hands of his Enemy Within might not be all it seems. Shortly before he's seemingly overtaken by The Darkness, a conversation between Jackie and Jenny ends with the odd exchange:

"CAN ANYTHING THREATEN THE WORLD AGAIN THERE CANNOT BE ANOTHER ENEMY SO STRONG OR CAN THERE"
 * Inversion in Serious Sam The Second Encounter -- the game starts with one of these. It's in the manual!
 * Once you play all the way to the end of Teenage Mutant Ninja Turtles: Fall of the Foot Clan on Game Boy. We get the ending shot of the Turtles having saved April O'Neil, while an epilogue tells us things might not be over... and then we see the Technodrome (presumably) fall into a pit of lava. The credits roll and once they are finished, we see a pic which says "The End" with a still image of Krang below it. Wait a few seconds and Krang villainously laughs (and his face clearly reflects his mood) and "The End" becomes "The End?"
 * Alone in The Dark: when Edward Carnby finally escapes from Derceto, he calls a taxi to go back home... and then it is shown that the driver is a monster.
 * In the second Drakensang game, after defeating the Final Boss, saving Nadoret  and watching the final cutscene... you're rewarded with a cutscene showing some thorwalian pirates arriving at Nadoret in the middle of the night. Is actually a sort of sequel hook for the expansion.
 * Blaster Master 2 for the Genesis ends with "THE END", then ellipses fade in to view one at a time, followed by a question mark.
 * Mega Man examples:
 * The original series rarely does this, but we get a glimpse of Wily's saucer escaping at the end of 3. And 6 appears to have a less open ending than its predecessors (instead of "dying", Wily is finally caught and jailed), but then "To Be Continued..." appears, making it obvious that he's got a plan.
 * The Mega Man X series does this more often than not, from Sigma's ominous message in X1 (wait a while after the credits) to Axl's fate and the question of Reploid destiny in X8.
 * Mega Man Zero 2 ends with an unknown agent activating something called "Omega". This would be a mere teaser for next game, except for one little detail... the bosses you've been fighting in these first two games have all had omega symbols on their health bars.
 * Mega Man ZX Advent ends normally unless you're on Hard. That mode ends with a cliffhangery Man Behind the Man revelation.
 * Mega Man Battle Network games 2 and 3 end with an indication that Bass is still out there. Interestingly, the payoff for BN 3's Bass scene comes in the postgame sidequests of that very game, not in the sequel.
 * The ending of The Last Ninja 3 is a nearly verbatim example, made hilarious by the total lack of punctuation.


 * Donkey Kong Country pulls a trick ending on a player while fighting the Final Boss Kaptain K. Rool. A brief credit roll with a "The End?" right as he gets up to fight another round.
 * In the finale of Asura's Wrath

Web Animation

 * Gotham Girls's third season ends with its Big Bad, locked up in a refrigeration unit, suddenly opening her eyes (which are red all of a sudden) and ominously breathing against the glass, cracking it.

Webcomics

 * Used as a deliberate spoof of the trope in this episode of Irregular Webcomic.
 * Spoofed several times in the end of a Sluggy Freelance arc. Each potential last minute plot twist is resolved immediately. Except for the last one, which was a joke.
 * Played straight, too.
 * Spoofed in this strip of Order of the Stick.
 * Played with in this strip of Looking for Group.

Web Original
"Sharktooth Bubs: Or did you?"
 * At the end of Kate Modern: Precious Blood, a brief glimpse of can be seen, cackling gleefully.
 * In the very last episode of Lonelygirl15, after even "The Ascension", posts a video entitled "In My Sights", saying.
 * At the end of the puppet sketch "Dangeresque: Puppet Squad" on Homestar Runner, the two Dangeresques caught the guy responsible for one time stealing their curly fries...

"Dangeresque: Or did I?"
 * Also the end of The theme from Dangeresque II: This time, it's not Dangeresque I.

""When the concept of universal gravitation was introduced, it quantified the forces involved and neatly accounted for the ocean tides. Today, anyone can tell you that the tides are caused by the "gravity" of the moon. Or are they?""
 * Played for laughs at the end of the first final (!) battle between AVGN and the Nostalgia Critic, with the Critic's bloody hand raising towards the screen after being defeated by Super Mecha Death-Christ.
 * Also a Running Gag used by the Critic, where he'll shout "OR DO THEY?!" as a Sting plays and the camera zooms in on his face. A couple of times he's subverted it by immediately backing off and saying "No, no, they do."
 * In Seeking Truth, the final blog post seems to indicate that . In Dreams in Darkness,.
 * Referenced in this wiki-answers article about tides.

Western Animation
"Death: Oh I'll be seeing you all, real soon. Ehehehe, is he joking? Hehehe."
 * Used for humorous effect in Family Guy, when, after Peter Griffin's epic fight with the chicken man, the camera zooms in on its unconscious form to see that it's still alive.
 * At one point, Stewie causes Matthew McConaughey to go down in an air accident and then says that Ron Howard is next. And then denies it. And then invokes The End (Or Is It?) (Scare Chord and all). And repeats those last two steps a few times over.
 * During an early season episode, Death has this awesome line:

"Early: Amen... pulls knife Or is it?"
 * In the Angry Beavers episode "Dag For Night", Dagget and Norbert's attempt at finishing the unfinished Oxnard Montalvo B-movie The Not Too Friendly Creature From the Off-White Puddle Who Will Eat You ends with "The End?", except Dagget melodramatically reads it as "The End... Question Mark?" That, and the movie ended with the Earth exploding.
 * still in one piece and possibly alive at the end of Transformers Armada. Sure enough, the rest of the Unicron Trilogy (natch) confirms this.
 * A favorite of various 80s cartoon villains, including Mumm-Ra and Megatron. One gets the impression that the writers had a variety of potential "deaths" for the bad guys in mind, and just wanted to get them all out of their system.
 * Used in the final (but not planned that way) episode of the Sat AM Sonic the Hedgehog series, not with Robotnik, but with ... and someone else.
 * Word of God is that the someone else was.
 * Parodied in The Simpsons, where "The End?" appears in an alternate ending of Casablanca.
 * And again in "Behind the Laughter": "The dream was over. Coming up next, was the dream really over? Yes, it was. Or was it?"
 * Another episode featured a Star Wars parody, specifically spoofing the prequels. The entire film is just the galactic senate deliberating on a budget issue. At the end, they finally reach a preliminary consensus, and Yoda, acting as speaker, says "tabled, this motion is.... or IS it?"
 * Spoofed in one episode of Freakazoid: "The End. Or is it? Yes, it is!"
 * Played straight in Batman Beyond: Inque gets one of these. Unsurprisingly, she comes back. Curiously, Big Bad Blight also gets a textbook The End (Or Is It?) in the first season's finale (to the point where Terry himself seems to completely expect that he'll come back), but never reappeared.
 * The opposite version of "The End?" appears at the end of the second season finale of Beast Wars after Megatron . Right before the credits, you see "To Be Continued..." followed by "?"
 * The Danny Phantom episode "The Ultimate Enemy" ends on this. The villain indeed was set to return for the Grand Finale, but the original writer was fired and replaced, resulting in an alternate outcome.
 * The highly er... surreal "The Mysterious Mr. Friend" episode of Rugrats ends like this.
 * Transformers Generation 1 ended "Enter The Nightbird" with a shot of Nightbird's optics lighting up just as she's being sealed away. It's not sure why, seeing as she's never used again.
 * Transformers Animated did this with a few of its one-shot villains, usually to leave open the possibility of their return. So far, most of them have come back at least once, so it's a useful strategy.
 * Played with in "The Laughing Fish" of Batman: The Animated Series. The Joker fell into the ocean very close to a hungry shark. Commissioner Gordon asks Batman a bit later if he thinks the Joker's really dead. Batman says he wishes so, but that he has his doubts. The camera closes in on the Joker card that Harley has thrown into the ocean in mourning and then it's eaten by the same shark, managing to make the viewer certain both that the Joker survived and that he did so only by the skin of his teeth (so to speak) at the same time.
 * In fact, countless TAS episodes end on this trope. Especially when they introduce new villains, the episodes always seem to end with a hint that the villain will return.
 * Happens for good guys, too. At the end of the episode in which Batgirl was introduced, Bruce Wayne straight-up says "I'm sure we'll be seeing her again."
 * ...each and every week. Always in more sexy and exciting ways.
 * The alternative ending in "The Good the Bad and The tigre" in El Tigre plays with this.In the "The End" screen,the Narrator questions "Or...does it?" adding a question mark,then clarifying "yes it does",thus removing the question mark.
 * In the opening credits of an episode of Futurama, "Or is it?" pops up on the title screen.
 * Galaxy Rangers pulled this with "Scarecrow." The titular villain is chased off, running away from a burning house and lit on fire. Shane, Niko, and Zozo are back on Ranger-1, preparing for takeoff, speculating on just what the Scarecrow was. As they take off, the technician that was gassing up their ship chuckles and melts, revealing the very much alive Scarecrow.
 * American Dad spoofed this in its giant James Bond parody episode "Tearjerker". Roger (as the titular villain) falls into an active volcano. The last scene shows the top of the volcano with the words "The End", but a moment later Roger's badly burned hand reaches up and grabs onto the "ledge", as a question mark appears. ...But then Roger loses his grip and falls back, the question mark disappearing as well.
 * This is the phrase Early Cuyler from Squidbillies uses to end his threat/prayers:

"Fanboy: Chum Chum! What did you do?! That was our only dollar! Chum Chum: Or was it? Fanboy: Yes, and you spent it! Chum Chum: Or did I? Fanboy: Yes! I saw you put it in the machine. Chum Chum: Or did you? Fanboy: Why do you keep talking like that? Chum Chum: Cause I lost our only dollar!"
 * In Fanboy and Chum Chum, "Dollar Day":

"Hoity Toity: Rarity, my congratulations. You are the most impressive fashion maven. Would you do me the great honor of allowing me to feature your couture in my best of the best boutique in Canterlot? Rarity: (happy gasp) Hoity Toity: Now, I'll need you to make a dozen of each dress for me by next Tuesday. Rarity: (gulps in fear) (cut to credits)"
 * Parodied in Spliced, when Peri and Entree are stalked by a golf cart they drove for a while and then abandoned. When they destroy the cart in the volcano, the characters comment that they're glad their ordeal is over. The screen then flashes the message Or Is It?, then shows the volcano again, and then says, "Yeah, it probably is."
 * Parodied in Johnny Bravo. At the end of The Color of Mustard, Pops concludes his story about Johnny's failed badminton career with an ominous "Or did we?" aimed at the audience. This is more of a Big Lipped Alligator Moment given Pops' tone of voice.
 * In the My Little Pony Friendship Is Magic episode Suited For Sucess:


 * Subverted at the end of the first South Park Halloween episode, "Pinkeye", when Zombie!Kenny bursts out of his grave... only for a statue from a nearby gravestone to fall on him. And then a jetplane crashes into him.
