It's the endgame at last, or at least close to it. The heroes have fought past the {{Mooks}}, dealt with the QuirkyMinibossSquad, even defeated TheDragon. They've caught up to the BigBad, and now it's time to rescue the hostage, and finally put a stop to their nemesis. There's just one problem: the BigBad is [[LargeAndInCharge big]]. Really, ''really'' big, and tall. Or, he's flying. Or piloting a HumongousMecha. [[BreadEggsBreadedEggs That's flying.]] Either way, the spot they need to reach to get to the hostage is very high up off the ground. There's ''no way'' they'd be able to reach that without flying.

Then, one of the characters steps forward. Hang on just a sec, guys, I have a sort of embarrassing secret to tell you...

A subtrope of TheReveal, with more specific revelation material: as it turns out, [[DeusExMachina this particular character has had wings on his back the whole time, keeping them secret]]. But now they need someone who can fly, and it's up to him.

See also WingedHumanoid. Can be a heroic OneWingedAngel. Can be combined with FreakinessShame. This particular revelation will usually be considered a LateArrivalSpoiler in promotional art from that point on.

!!Examples:

[[foldercontrol]]

[[folder:{{Anime}} and {{Manga}}]]
* In chapter 50 of ''Manga/MahouSenseiNegima'', Konoka is being held on the shoulder of a giant demon thing. Cue [[spoiler:Setsuna]] stepping forward...
-->"Here it is, my true form... I'm a monster, just like them."
** Of course, everyone else (like any reasonable person on the face of this Earth) [[FreakinessShame thinks that the wings are awesome]].
*** Mind you, she was justified, in that in her culture, white wings (like hers) were considered bad luck, and got her exiled from her tribe.
* When Saya falls from a skyscraper in ''Anime/BloodPlus'', Hagi jumps off and sprouts wings to rescue her.
* In ''Anime/VisionOfEscaflowne'' [[spoiler:Van reveals his wings while saving Hitomi from a fall]]. Dramatic enough, especially as Hitomi had been having [[PsychicDreamsForEveryone prophetic dreams]] about a winged savior for several weeks, and was distraught about the man's true identity. Moreover, the fact that he (and almost nobody else) has wings, and why he keeps them hidden forms a major part of the overall plot.
* [[spoiler:Nico Robin]] in ''Manga/OnePiece'' can sprout wings for five seconds. The usefulness of this is drama dependent. [[spoiler: That said, they aren't real wings, but just a lot of arms that she grows from her back and weave together so they look and work like wings. Her body part-cloning ability had been known for a long time, so it isn't an AssPull as much as it is just a very unconventional use of her powers.]]
* In ''Manga/SaintSeiya'', after the Wall of Lamentations dividing the [[{{Hell}} Inferno]] from [[{{Heaven}} Elysium]] [[TearJerker has been pierced]], the Saints find themselves faced with an infinite void of warped space. Conveniently, the Bronze Cloths (that had been splashed with drops of [[ChekhovsGun Athena's blood at the beginning of the story]]) can not only protect them from the instantly-lethal dimension, but also grow wings that allow them to fly to Elysium.
* Dragon Boy, the aborted original version of ''Manga/DragonBall''. The hero had dragon wings that he revealed only when he was doomed.
* Akira the ''Manga/{{Devilman}}'' literally pulled a pair of wings out of his back in order to stop a fall and then fight a flying demon. Since he's, well, a [[VoluntaryShapeshifting devilman]] that wasn't too much a surprise but still he never used or even demonstrated them before that moment.
* Beelzebumon from ''Anime/DigimonTamers'' sprouts a pair of black, feathery wings out his back when he goes into Blast Mode.
** A better example would be the Main character/main mon hybrid Dukemon who gains SIX angelic wings on activating his Crimson Mode.
* ''{{Anime/Pokemon}}'' has a weird example where a ''Leafeon'' [[http://www.youtube.com/watch?v=kNpOawWsFnA suddenly sprouts wings]] as a result of its Aerial Ace attack and teammate's Psywave attack combining. Needless to say, this can't happen in the games.
* [[Anime/EdenOfTheEast Diana, Seleção No. 11]], to escape the hotel room she was in. [[spoiler:It turns out it was an illusion, but, being Juiz's work, was a really good one.]]
* ''LightNovel/AccelWorld'' protagonist Haruyuki "Haru" Arita/Silver Crow does this as part of his special attack.
* ''Manga/DNAngel''. [[spoiler:Daisuke sprouts a pair of red wings to save Riku when they fall off a cliff and With isn't there.]]
[[/folder]]

[[folder:ComicBooks]]
* Happens to [[MeaningfulName Hawke]] near the end of the original run of the comic ''Tellos''. [[spoiler:He suffers lethal injuries during the flight, and when he dies, he turns into... you guessed it... a giant hawk.]] It had been foreshadowed several times: Hawke keeping some big secret was causing real problems in his relationship with his love interest.
** Heck [[ComicBook/{{X-Men}} Angel]] has (pun intended) pulled this one off multiple times, when in civilian clothing.
* On Several occasions, Batman does the equivalent with a jetpack.
[[/folder]]

[[folder:{{Film}}]]
* ''TheDarkCrystal'' had a variation. Just as the two protagonists are falling off a cliff, the girl sprouts wings. It turns out only girls of that species have them, but since it's never mentioned before...
** ...except in some carvings you don't get all that long to look at, and it isn't really clear that the wings on some figures are actually for gliding, rather than just sartorial whimsy.
* TheIronGiant doesn't find out he has boosters on his feet until he accidentally falls off a cliff and they activate automatically.
* In a villainous variant, ''JeepersCreepers'' didn't reveal that its demon/monster/alien ''thing'' had wings until it'd been shown on screen several times.
* Film/PacificRim gives us Otachi.
[[/folder]]

[[folder:{{Literature}}]]
* Justified with Aziraphale and Crowley at the end of ''Literature/GoodOmens''. The two characters in question are known to be an [[OurAngelsAreDifferent angel]] and [[NobleDemon demon]] throughout the entire story. It's only at the end when they [[spoiler: face off against Lucifer and think they're going to die]] that they decide they might as well go out the way they came in.
* This happens to the Karnee folks in Holly Lisle's ''[[Literature/TheSecretTexts Matrin]]'' books, who also have to fall off a mountain or a building or something in order to fly.
[[/folder]]

[[folder: LiveActionTV]]
* Done in one of the ''Series/KamenRiderDouble'' movie by [[spoiler:Double himself, in his Cyclone Joker Gold Xtreme mode. It's only for a few minutes, enough time to to stop falling off Fuuto Tower and defeat the villain, but it's CrowningMomentOfAwesome while it lasts.]]
[[/folder]]

[[folder:{{Music}}]]
* The MusicVideo for Asian Kung Fu Generation's "After Dark" features a man randomly sprouting wings on his back one day, and desperately hiding them until some window-washer is dangerously close to falling off a building. AwesomenessEnsues.
[[/folder]]

[[folder:VideoGames]]
* Played kind of lopsided in ''Franchise/KingdomHearts'' I and II. For both of the ginormous final bosses, you suddenly gain the ability to fly through the air, without wings. It sort of makes sense because in I, there's a level you could already do this. In II, you ''can'' get this ability beforehand, but only at an ungodly high level. In the usual player's case, both are the gameplay equivalent of a GiantSpaceFleaFromNowhere.
** It's actually more of a ChekhovsSkill from Sora and company's time in [[PeterPan Neverland]] in the first game and a function of Sora's [[ClothesMakeTheSuperman costume upgrade]] in the second. In the first game Sora only starts flying during the final battle after gaining the resolve to fight in a variation of ThinkHappyThoughts with HeroicWillpower. The example in II could be [[JustifiedTrope justified]] or [[HandWave hand waved]] as space-time being completely distorted in the final battle with Xemnas, as eventually your fighting arena is reduced to a black and white void.
* InteractiveFiction example: ''VideoGame/{{Photopia}}''. The way to escape TheMaze is to remove your spacesuit, then [[spoiler: 'go up' or 'fly']]. (If you wander around long enough, a gentle breeze on your back will give you a clue.) The author [[http://adamcadre.ac/content/phaq.txt mentioned]] that he got the idea from Ron Hansen's ''Mariette in Ecstasy''.
* [[spoiler: Lloyd]] in ''VideoGame/TalesOfSymphonia'' suddenly sprouts wings to save the world in the ending. Though this was not ''entirely'' unexpected, as [[spoiler:his Exsphere]]'s special nature had been foreshadowed for much of the game.
* In ''VideoGame/{{Grandia}}'', the [[{{Precursors}} Icarians]] are a winged race that has entirely died out - except for [[spoiler: Leena and her sister Feena. The latter is revealed when she and Justin fall off an airship]].
* Eddie suddenly gains the ability to sprout awesome-looking demon wings in ''BrutalLegend.'' Apparently ThePowerOfRock has to be invoked, because the wings disappear whenever he's not in a Stage Battle.
** [[spoiler: Turns out, he's half-demon. His mom was Succoria. Not, as he thought, his girlfriend...oops.]]
* In ''WorldOfWarcraft'', Baron Sablemane at first gives the player lots of things to help them kill the gronns. At the end of the chain, in Alliance version, he personally help the player to fight Goc, starting with some...questionable words, and shortly after transformed into his true form, he is a black dragon all along. Once finished, he even apologized to the players for his "startling transformation".
[[/folder]]

[[folder:{{Webcomics}}]]
* Aldran, the necromancer and party leader in ''Webcomic/{{Antiheroes}}'', didn't reveal that he has wings until the party confronted his archenemy [[spoiler: and twin brother, who also has them]]. May be justified by his secretive personality, as he didn't even admit his name was Aldran until the 36th strip.
* Marsha in ''Webcomic/CollegeRoomiesFromHell''. After being bitten months ago by vampire potatoes. She found out when she was about to kill herself by jumping off a tall building, but changed her mind, but then the cat with a piece of Dave's soul surprised her and she fell off.
* Happens in about half of Aylee's forms in SluggyFreelance. Apparently her [[InvoluntaryShapeshifting body has decided that it's too useful not to have flight]].
[[/folder]]

[[folder:WesternAnimation]]
* The Monarch's henchmen ''themselves'' didn't know the wings on their butterfly-themed costumes could be used to fly until someone tried to in the ''second season finale'' of ''WesternAnimation/TheVentureBrothers''.
** The Monarch also reveals that he can fly in the first episode of season two. It's supposed to be this grand reveal, but as the writers point out, it's done so casually that you're just left wondering when you missed him flying the first time.
* In one of the ''WallaceAndGromit'' films, Gromit is heading toward a cliff in a runaway motorcycle sidecar, falls off, and...pushes some buttons that suddenly cause it to sprout wings and a propeller.
* Lavana in ''WesternAnimation/BRATSOfTheLostNebula''. Twisted in that it's only the second episode, and the rest of the team knew all along - they just didn't tell the guy that was patrolling with her.
* The series-ending "Endgame" of ''TransformersAnimated'' is a variation on this: [[spoiler:Megatron has captured the massive Autobot Omega Supreme, and in order to combat him should Megatron try to use him against the other Autobots, Ratchet and Sari build a jetpack with wing stabilizers for Optimus Prime]].
