->''I will not turn into a snake. It never helps.''
-->-- EvilOverlordList, Rule 34 ([[IThoughtItMeant no, not that]] [[RuleThirtyFour Rule 34.]])

Okay! The heroes have made mincemeat out of the EvilMinions, [[StormingTheCastle stormed]] their way through the [[TheVeryDefinitelyFinalDungeon Dungeon]] and into the SupervillainLair or [[EvilTowerOfOminousness Evil Tower]] and come face to face with the BigBad. It's time for the BigBad to pull out all the stops and do something really impressive! He chants his BlackMagic, and/or [[AppliedPhlebotinum throws the impressive switch]] and...

A snake? Is that the best you can do?

Oh wait, it's a [[OurDragonsAreDifferent dragon]]? Well, I suppose that's a little better, but not much.

Seriously, is that all? Cause we can wait until you think of something better. Take your time.

I mean, we brought along a mongoose specifically for this situation.

Seriously, there's probably something [[WhatDoYouMeanItsNotSymbolic symbolic]] about the tendencies of a villain to turn into a snake. In the West there is a strong established symbolism for snakes from TheBible (most famously the serpent in the Garden of Eden, although some translators believe that the original text may have indicated that the creature was closer to a dragon than a snake), Norse Mythology, and there's {{Orochi}} in Japanese mythology. Adding onto this, there is the fact that when walking in the wild, it's generally not a good idea to stop and pet a snake.

Of course, the result of all that symbolism is that there can be no doubt about the [[DesignatedVillain evil nature]] of a foe, and it gives TheHero a [[WhatMeasureisANonCute comfortably scary foe]] to [[NotEvenHuman kill]]. Despite how easily this tends to end with the villain chopped up on the hero's sword, villains everywhere still love the order Squamata because, of course, ReptilesAreAbhorrent. How often have you ever seen a villain turn into a koala, a rhino, or something that would actually be useful?

In short, a specific and much overused variant of OneWingedAngel.

!!Examples where it doesn't work:

[[foldercontrol]]

[[folder: Anime and Manga ]]

* Near the end of the [[FullmetalAlchemistAnime first]] ''[[FullmetalAlchemistAnime Fullmetal Alchemist]]'' [[FullmetalAlchemistAnime anime]], [[spoiler:Envy turns into a giant serpent in order to cross the Gate and kill his father, Hohenheim. He ends up getting stuck in [[WeimarRepublic Germany]], where he's captured by the Thule Society and used as a giant Ouroboros to activate their trasmutation circle and open a portal to Amestris]].
* Orochimaru from ''{{Naruto}}'' probably takes inspiration from his namesake {{Orochi}} and does this in the series. [[spoiler:He gets taken out by a certain IneffectualLoner after said loner's FaceHeelTurn]]. Lamen noodles, especially since it means he can't perform any of the jutsu that were his goal in life to learn. Though [[spoiler:his chances as a snake were probably better than a drugged-up old man who was near-dying, and he apparently didn't have a choice in the matter]].
** Rather, Orochimaru takes his inspiration from the original Orochimaru, who likely gets it from ''his'' namesake Orochi.
** He does it again later, this time turning into a ginormous eight-headed hydra. It didn't end well.
*** More specifically, he takes on the Hydra form to fight and attack called Susano, named for the god that killed the eight-headed serpent Orochi. As this troper's friend said to him, "he was mythologically doomed to lose that fight."
* A MonsterOfTheWeek from ''{{Inuyasha}}'' does this. Notable as he actually put up a pretty decent fight while in humanoid form, (thanks to a magic trident) but got carved up like a Thanksgiving turkey post transformation. Beyond lame.
** That's technically a reversal; said monster was a water snake spirit who stole the trident from the local river goddess, so he didn't change into a snake, he changed ''back'' from his assumed human form.
* In recent ''OnePiece'' chapters, Boa Marigold and Boa Sandersonia turn into half snakes. They do pretty well against Luffy until he stops holding back...

[[/folder]]

[[folder: Comic Books ]]

* The MarvelComics character Moondragon, who despite her name was a human with psychic powers and [[ArrogantKungFuGuy Arrogant Kung Fu]], recently turned into a literal dragon for no reason-- and then got killed. (Well, a lame reason was given, because her backstory involved an evil [[EnergyBeings Energy Being]] called the Dragon of the Moon (who was also not really a dragon) who had manipulated her into being its BastardUnderstudy since childhood, then got KilledOffForReal yet supposedly years later turned her into a real dragon... Oy. ComicBook writers seem to have lost the skill of [[DidNotDoTheResearch basic research]] into the characters they write, explaining why {{Ret Con}}s and ReWrites have become increasingly common.)
** The latter one was an inverted, she turns into said dragon to save the day, and is "killed" (the whole [[EnergyBeings Energy Being]] part) by Ultron, an evil robot that looks liked a KnightInShiningArmor.

[[/folder]]

[[folder: Film ]]

* ''{{Enchanted}}'': Narissa pulls a Maleficent-crossed-with-''KingKong'' when she turns into a dragon, [[JamesBondage kidnaps Robert]], and climbs a skyscraper during a thunderstorm. Bad idea. The result is impressive, though.
** [[YourMileageMayVary Somewhat]] [[NightmareRetardant lessened]] by the fact that she ''won't shut up''.
*** And by the puns. [[IncrediblyLamePun Oh god, the puns...]]
* ''{{Beetlejuice}}''.
* ''{{Conan the Barbarian}}''.
* Although not her actual intention, when the villainess of the live-action ''Film/{{Casper}}'' movie dies and becomes a ghost, it more-or-less follows this trope in practice. It doesn't work out for her very well, though.
*Used and averted in Disney's ''TheSwordInTheStone''. Merlin and Madam Mim have a wizard's duel. Madam Mim, [[LoopholeAbuse who announces the rules at the start, breaks them]] in an attempt to beat Merlin, only to have Merlin go in exactly the opposite direction. He makes her sick, which pushes her to bed rest.
** In [[TheOnceAndFutureKing the original novel]], she died of it on the spot.
* An unintentional example in the [[RunningGag otherwise forgettable]] ''BartokTheMagnificent'': the villainess is turned into a dragon after downing a potion. If you'd like an idea of why that scene's popular, it's referenced on ''two'' FetishFuel pages.

[[folder: Literature ]]

* The Lady of the Green Kirtle does this in [[{{Narnia}} The Chronicles Of Narnia]]: ''The Silver Chair''. Lewis was definitely being symbolic in this case, but it's still a dumb move, especially when confronted by a [[LawfulStupidChaoticStupid Good Stupid]] hero who WouldntHitAGirl but has no problem cutting a giant serpent in half. Lame.
** In another incident in the same series, a ''protagonist'' is turned into a dragon for being greedy (again, symbolic). For some reason, a teenage boy treats this like it's a bad thing.
***To be fair, he was apparently an old-style gangly ugly dragon. And he had a metal ring digging painfully into his arm the entire time due to his increase in size.
*** The various practical problems of dragonhood are thoroughly expounded on in his situation, and anyway, it had already been established that Eustace wasn't into that scene, "having read none of the right books."
* In ''ThePrydainChronicles'', when EvilOverlord Arawn, (based on the Celtic God of the Dead, who shares the name), master of terrible armies and incomprehensible BlackMagic is finally confronted face to face, he promptly turns into a serpent and dies within a paragraph or two, managing only to kill the slightly less evil queen before falling to everyone's favorite assistant pig keeper. Lame.
* In ''TheDeathGateCycle'', the ultimate evil beings are [[ShapeShifting shape shifters]] that like to take the form of [[OurDragonsAreDifferent giant dragon-snakes]], probably meant to resemble wingless Chinese dragons with a more snakelike head. In a final confrontation with the heroes one of them reverts into this shape, growing too large, and his head hits the roof of the room they're in, which is inscribed with death runes, killing him. ''Uber'' Lame.
* The universe of Steven Erikson and Ian Cameron Esslemont, best known from the ''MalazanBookOfTheFallen'' books, features the Soletaken, who can change ("veer") from humanoid to beast form. Some Soletaken veer into draconean ''[sic]'' form, which is powerful, but somehow never seems to really work out in the story. Examples:
** ''Gardens of the Moon'' (book one): Silanah (a true dragon, not a shapeshifter) and four [[DarkIsNotEvil Tiste Andii]] Draconean Soletaken [[spoiler:face off against Raest, the Jaghut Tyrant. He chases them off.]]
** ''Gardens of the Moon'' (book one): [[AntiVillain Anomander Rake]] veers into draconean form and [[spoiler:flies over Darujhistan, but he doesn't accomplish anything, and sembles back to humanoid form to fight a Malazan demon]].
** ''Memories of Ice'' (book three): Anomander Rake veers into draconean form to harry a horde of humans, which should be a trivial task. But [[spoiler:one of them, Anaster, somehow poisons him, and Rake shies away. Then he takes humanoid form in order to kill some measly witches.]]
** ''Reaper's Gale'' (book seven): In the prologue, Scabandari Bloodeye, in draconean form, [[spoiler:fights two Elder Gods and is killed]].
** ''Reaper's Gale'' (book seven): Menandore, Sheltatha Lore and Sukul Ankhadu, in draconean form, face [[spoiler:two measly humans (Quick Ben and Hedge). All three end up badly wounded and getting killed soon after]].
** ''Reaper's Gale'' (book seven): In the ultimate anticlimax to this book, [[BadAss Silchas Ruin]] (Anomander Rake's brother) faces [[spoiler:(again) a bunch of measly humans and gets his butt handed to him]].
*** Apparently the only time this ability was used successfully was in ''House of Chains'' when Osseric veered into a dragon to [[spoiler: fly his son L'Oric out of the crumbling memory of Raraku]].
* In the ''DragonKnight'' series, James actively avoids turning into his dragon form during battle unless he needs to intimidate his enemies. While he ''is'' big and scary, he's also extremely vulnerable and unable to move as quickly or nimbly as a human foe.
* During a magic-transforming fight in {{Discworld}}, at one point the wizard transforms into a snake, but then Granny Weatherwax transforms herself into a ''snake charmer's basket'' as a counter.

[[folder: Live Action TV ]]

* This was actually the end goal of the Mayor from Season 3 of ''BuffyTheVampireSlayer'', which he'd spent a '''century''' working towards and built all sort of elaborate machinations around. He promptly gets taken out by [[IShallTauntYou Buffy taunting him]] and [[{{Understatement}} a little]] well placed dynamite, while a bunch of high schoolers mostly armed with crossbows and such fight off his minions. ''Lame'' lame.
** But hilarious-aside from his undeniably evil aspirations, he's been characterized as a personable, mildly absent-minded guy who [[GoshDangItToHeck doesn't like swears.]] His only comment on his seconds-nigh doom? "Well gosh!"
** It is also implied that his giant snake form was only temporary, something that he had to pass through on his way to a higher plane of existence.

* [[ClassicalMythology Greek]] [[OlderThanDirt mythology]] example: the river god Achelous turns into a serpent to fight Hercules for the hand of a princess called Deianeria. He loses, and in one version Hercules rips off one of his horns, which was used by the nymphs to make the Horn of Plenty.

* Maleficent, the BigBad from Disney's ''SleepingBeauty'' and a major villain in the ''KingdomHearts'' games turns into a dragon at times of danger. In the game she gets smacked down by a preteen kid wielding a giant key. Lame to the power of lame.
** Bah, that's just because she didn't call on [[NightmareFuel all the powers of Hell]].
* Nobody's mentioned the [[DragonWarrior Dragonlord]] yet?
** Or the [[DragonQuestVIII Lord of the Dragovians]]?
* ''EyeOfTheBeholder 2'' has a seemingly regular wizard turn out to be a Dragon. Of course, the dragon is still vulnerable to the attack+side-step maneuver.
* ''TheWorldEndsWithYou'': The FinalBoss first fights you as human. This is probably the hardest fight you're [[BonusBoss required]] [[HopelessBossFight to win]] in the game. Then the turns into a snake. This is very easy. Then he turns into dragon, which is at least something of a challenge.
* No pity for [[MegaManStarForce Luna]]? Especially after she's forced into this due to the [=FMian=] Ophiuchus hijacking her? Thankfully, Geo beats her back to normal and Gemini slaughters the smug snake, but still...
** On a side note, why wasn't [[DrillHair Luna's hair]] as Queen Ophiuca/Ophiuchus Queen ued as a weapon? It was VISIBLY ROTATING!

* A ''protagonist'' [[SuperMode turns into a dragon]] during TheSiege in the sixth book of ''The Death Gate Cycle''. He kicks a lot off ass (mostly off-screen, but considering what he's facing it's still badass). It's only a partial success because he ends up missing in action. The seventh book reveal why: [[spoiler:he was defeated and captured by a real dragon. And not the lame kind mentioned above, a "one person in the entire series has defeated one in battle" dragon]].
* This plays into the final ''{{Animorphs}}'' book. Rachel has snuck aboard Tom's ship, hoping to defeat his rogue Yeerk army. She [[SuperMode transforms into a Grizzly Bear]] and he sends his minions after her after they have each changed into equally fearsome and tough creatures. Rachel has ''just'' enough of an opportunity during the battle to check on Tom as he hangs back and transforms - into a very small but very poisonous snake. [[spoiler:After Rachel has defeated each of the minions, she bites Tom in half. She demorphs, exhausted, and another minion, transformed into a polar bear, kills her with a single blow.]]
* Mister Monday transforms into a giant snake in the first book of the ''KeysToTheKingdom'' series, He ALMOST succeeds in killing Arthur, until Arthur [[spoiler: gets Suzy to write on him with her fingers and a bottle of ink, causing him to be attacked by hundreds of text-destroying, acid-spitting Nithling-snakes]].
* In ''TheSilmarillion'', Sauron transforms into a serpent (as well as a monstrous wolf and a vampire) to defeat Beren and Luthien. He holds his own but is still driven off.

* Draconis and Abazigal from ''[[BaldursGate Baldur's Gate II: Throne of Bhaal]]'' revert to their [[OneWingedAngel true forms]] -- adult dragons -- upon being whacked sufficiently while in human form. While you still kill them, the 'partial success' part is because Draconis' dragon form is a challenge (or at least a ''bloody'' annoyance) and is widely considered to be an actually difficult boss. Abazigal, however... Isn't.
* After being thrashed sufficiently by Isaac's team in ''GoldenSun'', antagonists Saturos and Menardi transform [[spoiler:into a single two-headed dragon. While the Fusion Dragon is a more powerful boss than either opponent separately]], team Isaac still wins. In the sequel, the final boss is actually [[spoiler:another fused dragon comprised of three of the heroes' parents.]]
* Avaritia, the leader of the Black Knights in ''[=~11eyes~=]'', stays on the sidelines for most of the game. Come the final fight, he transforms into a gigantic black dragon. Kukuri and Shiori face him down, and, though it takes a hell of a lot of power from Shiori, they just barely end up victorious.
* In a heroic version, Aelia of ''ValkyrieProfile'' turns into a dragon briefly during her {{finishing move}} to fire a giant beam at enemies. It only partially works because it's a bit weaker than most anyone else's finishing move, and is even less useful when you consider the one hit does little to help the ComboMeter.
* In ''BreathOfFire 4'', [[EnemyWithout Fou-lu]] transforms in dragon twice: one extremelly bulky and powerful and other latter slimmer but who could [[HpToOne tunr the whole party HP to one]] - and he would ALWAYS use on the FIRST turn. Made even harder because that was a SequentialeBoss, since you spend most of your healing resources on the first dragon. ThatOneBoss for many indeed.

[[folder: Western Animation ]]

* The EvilutionaryBiologist Grimsby Roylott turns himself into a giant snake-creature in order to slip into buildings through the air vents in the ''SherlockHolmesInTheTwentySecondCentury'' episode "Scales of Justice" (Holmes affictionados will recognise this plot as being just barely based on "The Adventure of the Speckled Band"). It also helps in his fight with Holmes, but not as much as he'd hoped.
*''DannyPhantom'': While the second episode that showed a dragon (transformable via a [[ClothesMakeTheManiac magic pendent]]) played this trope straight, the second, more evil one, was much, much harder for the hero to defeat. In fact, his abused little sister was the one who ended it, but not before he created some serious damage.
* The ''BatmanBeyond'' episode "Splicers" has the villains mix animal DNA with their own. While the lead villain uses DNA from several different animals, he winds up as basically an eight-foot-tall snake [[spoiler: (at least until Terry overloads him with injectors and he [[OneWingedAngel turns into a monster]])]]. He puts up a fairly decent fight against Batman (certainly better than he would have as a human), but still loses in the end.

** In a bit of a subversion, the ''Eventide'' set gave us [[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=157401 Snakeform]], which has the (temporary) [[ExactlyWhatItSaysOnTheTin obvious effect]] on the affected creature...which in the process [[BalefulPolymorph loses all its special abilities for the duration and generally becomes much weaker as well.]] So you obviously shouldn't be using it on ''your'' creatures...

* ''Comicbook/TheLastTemptation'' graphic novel by NeilGaiman and AliceCooper (yes, you read that right) has The Showman turn into a giant snake at the end, but he doesn't actually attack the hero. He just messes with his head a bit, and scares him away. And according to "Welcome To My Nightmare", it was an entirely successful head-mess, because by then, Stephen is now a SerialKiller.

* At first, Thulsa Doom of the ''ConanTheBarbarian'' movie seems to be doing this for no reason at all, but then subverts the expectations of the audience by fleeing through a hole in the wall made for a snake and getting to safety. (It's also in keeping with his character so far as he seems to have a thing for snakes: his religion worships them, he has a pet snake that Conan kills, he has ''[[TrickArrow snake arrows]]''... no, really.) Thus, not lame.
* Jafar does this in ''{{Disney/Aladdin}}''. To the surprise of many, it actually works OK for him. (And to his credit he has the good taste to use a cobra as the type of giant snake to turn into, adding onto the menace). He fails when Aladdin tricks him into upping the OneWingedAngel ante by turning into a genie, trapping him in a lamp. He would have won if he had just stayed a snake.
