** It's even screwier when you consider that Rayquaza, essentially a sky monster, ''comes out of a random lake.''
*** Considering there is actually a level set in the sky, the fact that Rayquaza comes out of a lake makes even LESS sense.
*** Screw "sky monster", Rayquaza is the EMBODIMENT of the skies. Fighting '''Kyogre''' in that lake would have made '''''far''''' more sense. Hell, fighting a ''Gyarados'' would have made more sense ([[TheyWastedAPerfectlyGoodPlot and would have made for a great]] CallBack [[TheyWastedAPerfectlyGoodPlot to]] [[VideoGame/PokemonGoldAndSilver the Lake of Rage]], [[TheyWastedAPerfectlyGoodPlot too]]).

** The Commander Shroob from Partners In Time is a noteworthy one, especially since he's the only Shroob you encounter on Star Hill. The Elder Shrooboid is a mixture of this and DiabolusExMachina, since before he fights you, [[spoiler:he turns Kylie and Toadbert into mushrooms to prevent them from telling you the truth about the Cobalt Star]].
*** [[spoiler:No, that's probably what the player is ''supposed'' to think... Notice that it doesn't use any similar abilities in the battle, and that the Cobalt Star shows up after you beat him?]]

** Mammoshaka. You never know there's a powerful guardian on Mount Pajamaja unless you speak to one of the trapped Pi'illos on the mountain, otherwise you won't until you literally see it in the cut scene just before the fight. It's supposedly legendary... but no one ever mentions it except for said Pi'illo and the Massifs about 30 seconds before the battle.

** The Crystal King, boss of chapter 7, is the only plot-required boss in the game that isn't even ''hinted'' at before you meet him at any time in the chapter.

** In Brawl, we have Tabuu. Throughout Subspace Emissary, we're led to believe that it's Master Hand running everything behind the scenes, as usual. Then suddenly we find out that Tabuu has been using Master Hand like a puppet the whole time. This trope seems to be a staple of the Smash Bros series.

* The ''VideoGame/{{Kirby}}'' franchise contains many of these, barring the recurring bosses, most notably Whispy Woods and Kracko, major characters, and whoever is the BigBad, BiggerBad, or FinalBoss... usually. There are some bosses that can be called the FinalBoss of the game (sub-game in ''VideoGame/KirbySuperStar'' and its remake) that come completely out of nowhere. Most notable are the Wham Bam Rock in ''Super Star's''' The Great Cave Offensive, even more so in the remake when he gets special boss music, Miracle Matter in ''Kirby 64'', and [[spoiler: Dark Nebula]] in ''Kirby Squeak Squad''. Yes, the last of these explicitly has plot relevance, but very little.

* The BigBad of ''{{Anachronox}}'' is not revealed until the very end[[hottip:*:You ''can'' actually see him while on a trip to Sunder.]], his name is not revealed nor anything is known about him. It doesn't help that the game was supposed to [[SequelHook have a sequel]].

** Ultros from ''VideoGame/FinalFantasyVI'', the most amusing Space Flea ever. He's a giant purple octopus who comes out of nowhere and tries to eat the party. When you give him a beating, he escapes and later comes back to wreck the opera you're attending, along with other situations, for revenge. It's even funnier if you pick Gau and Cyan to go to the opera house. Why? Because this means your party is made up of members Ultros has never met before, and thus he's plotting "revenge" against a pack of total strangers.

** The Zeekeeper. No one expects to see the god like figure they're reviving to take down the BigBad end up their opponent in a giant boss battle, especially given how Dreamy Luigi's actions are the only reason it fights to begin with...

** Mammoshaka. You never know there's a powerful guardian on Mount Pajamaja until you literally see it in the cut scene just before the fight. It's supposedly legendary... but no one ever mentions it except for the Massifs about 30 seconds before the battle.

** At the end of ''[[VideoGame/TheLegendOfZeldaTheWindWaker Wind Waker]]'', you march into Ganondorf's lair and prepare to fight him...he suddenly leaps up to the ceiling, and makes you fight several giant magical puppets [[MythologyGag modeled on bosses from previous games]]. Afterward, you have to laboriously climb up the puppet strings before you get to actually fight Ganondorf himself.

** The Mars People appeared first in ''Metal Slug 2'', with small, ''small'' clues in the game before they showed up, so their appearance in part 3 isn't entirely unexpected. No, the real kicker was in Metal Slug 6, when ''different'' aliens show up out of nowhere and start ''eating'' the Mars People.

* ''VideoGame/CaveStory'' is solid for most of it (even the fight against a tiny superfast mushroom makes sense). Monster X and Ironhead, on the other hand, are ''literally'' out of nowhere. All the latter gives you is "Something's coming", and the former just suddenly tries to run you over once the boss music suddenly starts (and its dying cutscene is [[BigLippedAlligatorMoment even more bizarre]]). Interestingly, Ironhead is [[TheCameo pulled directly out of]] [[SwimIkachan one of the creator's earlier games.]] There's also Omega, which unlocks the sun stones in the Sand Zone, and Heavy Press nearly qualifies- however, after beating him, it's revealed that his LoadBearingBoss nature is the only way to get to the final final FINAL final boss chamber.

** Ultros from ''VideoGame/FinalFantasyVI'', the most amusing Space Flea ever. He's a giant purple octopus who comes out of nowhere and decides to fight you for no reason. When you give him a beating, he escapes and later comes back to wreck the opera you're attending, along with other situations. No one knows why he hates the player characters so much. It's even funnier if you pick Gau and Cyan to go to the opera house. Why? Because this means your party is made up of members Ultros has never met before, and thus he's plotting "revenge" against a pack of total strangers.

* At the end of ''RainbowSix: Vegas 2'', Bishop states that he/she must take down Gabriel Nowak him/herself, however, once the big showdown comes an attack chopper shows up instead of a one on one vs Nowak. It is completely unexpected in the sense that the whole game has you facing only human terrorists.

* The final stage of the story mode of ''[[FZero F-Zero GX]]''. Most of the story involves Captain Falcon taking on Black Shadow and Deathborn, both of whom are introduced in the first cutscene. Nothing vastly out of the ordinary until the final stage, where, just as the story is being wrapped up, [[spoiler:three ghosts representing the developers appear and announce that Deathborn was wrong about everything. They then challenge Captain Falcon to a race in a kind of digital dimension. He defeats them, they vanish, and the story just ends there.]]

-->-- '''[[WebVideo/TheAngryVideoGameNerd The Angry Video Game Nerd's]]''' review of ''[[Franchise/{{Transformers}} The Mystery of Convoy]]'' [[hottip:*:It's actually someone who makes marginally more sense, [[http://tfwiki.net/wiki/Trypticon_%28G1%29 Trypticon.]]

Also, note that most games that include RandomEncounters, or that have no thematic consistency to their enemies, are pretty much incapable of having a GiantSpaceFleaFromNowhere. In those games, even the normal enemies appear suddenly and without any connection to the story; the bosses are therefore just a plain old instance of GameplayAndStorySegregation, same as the normal battles.

* [[DiscussedTrope Discussed]] in the elaborate StrategyGuide for the remakes of both ''{{Lunar}}'' games. The developers chose to remove several [[GiantSpaceFleaFromNoWhere Giant Space Fleas]] that could distract from the main narrative. Of course, the remakes put a lot more emphasis on some of the baddies that ''did'' make sense.

** In [[Disney/{{Fantasia}} his original appearance]], Chernabog isn't really given a backstory either. The ''Night on Bald Mountain'' begins with him turning out to be the top of a mountain and proceeding to terrorize a nearby village in some pretty frightening scenes. Therefore, he could perhaps be considered a GiantSpaceFleaFromNowhere in Fantasia as well.

* In ''DawnOfWar: Winter Assault'', there are two campaigns, Order (Imperial Guard and Eldar) and Disorder (Orks and Chaos). If you play the Disorder campaign before you play the order campaign you will be immensely surprised in mission five when [[spoiler:Necrons, whom you had no knowledge of even being in this system, let alone coming to this planet, land and attack you. When you play the Order campaign it is explained by the Eldar characters that the Necrons are coming and why they want to attack.]] But if you play Disorder without playing Order first they seem like a GiantSpaceFleaFromNowhere.

* The PC game for ''[[VideoGame/HarryPotter Harry Potter and the Sorcerer's Stone]]'' has Harry escaping from the astronomy tower, pursued by Filch, to a Quiddtich game, and then randomly under the trap door - leading to the final battle with Voldemort. The game skips about half of the book and movie.

* ''HaloReach'''s third mission "Nightfall" has you fight a pair of giant reptilian [[KillerSpaceMonkey space monkeys]] (no, [[{{Halo2}} not the]] [[{{Halo3}} Brutes]]) called Gútas from nowhere about halfway through. Originally they were going to appear in more missions, but ended up being cut from most of them except that level.
* In ''DeadToRights'' at the end of the warehouse level, Jack Slate finds the guy he was chasing (Gopher) killed, and the person who killed him is...some random hulking dude with a crossbow called Longershoreman X who you then fight in a boss battle, this guy has zero build-up and there's no mention afterwards as to who he was or why he killed Gopher.
* ''VideoGame/MetalGearRisingRevengeance'' has the Metal Gear EXCELSUS, piloted by Senator Armstrong. Even more-so is [[spoiler:Armstrong himself, who afterwards bulks up and induces TheWorfEffect upon Raiden]]. Even the Mission Control is shocked, since if you talk to Kevin beforehand, he'll note that [[spoiler:there's nothing they dug up on Armstrong that could have suggested that he was in any form physical threat (aside from the fact that he was in the Navy but didn't see any action)]].

** ''VideoGame/FinalFantasyIV'' ups the ante with Zeromus, its final boss. He had only a vague connection to the plot, being the hatred of the main villain given form, and seemed to be present largely to provide a massive, intimidating final boss--which Zemus [[TheManBehindTheCurtain very much wasn't.]]

*** Siegfried/Ziegfried. He is a joke boss on the Phantom Train, also appearing in [=WoR=] Cave of Figaro and the Coliseum, who has no relevance to the story whatsoever. He is a "legendary" thief who has some relation to Ultros (this is not explained in detail) but despite being "legendary" the only two characters that mention him are himself and Ultros. It is probable that the version on the Phantom Train is actually an impostor, but this just adds to the randomness.

** In ''FinalFantasyMysticQuest'', the Snow Crab, Jinn and Medusa appear at the end of dungeons with no purpose except to give a boss fight. However, the Behemoth puts them to shame -- it is fought at the start of the game and literally appears from nowhere, suddenly manifesting directly behind the player character and attacking them with no warning or reason.

*** Not that Dragon Quest VIII is without them, though. Megalodon and Ruin (from when you're trying to escape [[spoiler:The Black Citadel]] both fit this trope pretty well.

* ''[[VideoGame/MarioAndLuigiSuperstarSaga Mario & Luigi: Superstar Saga]]'' had Trunkle, a rock-creature who suddenly appears at the end of the desert section to menace the princess for a distinctly nonspecific reason.

*** [[spoiler: No, that's probably what the player is ''supposed'' to think...Notice that it doesn't use any similar abilities in the battle, and that the Cobalt Star shows up after you beat him?]]

** There's also Kent C. Koopa, who you encounter on Pleasant Path. He literally shows up from out of nowhere to block your path for no good reason. You can either fight him or pay him a temporary toll, and it is absolutely necessary to use the path, so...(Actually there's a sign in the Mushroom Kingdom that foreshadows his existence. Make sure to read both sides of it each chapter).

** In ''SuikodenIV'', at the climax of the game, you fight [[spoiler: a [[WhenTreesAttack Giant Space]] ''[[WhenTreesAttack Tree]]'' [[WhenTreesAttack From Nowhere]]. [[ItMakesSenseInContext It's actually explained]] in the game's {{Backstory}} -- and [[SuikodenTactics the sequel]] clears things up for those who didn't piece things together on their own -- but still, it's very much a [[BigLippedAlligatorMoment WTF moment]] at the time.]]

** Apparently, when they were asked about him being in the game, the devs stated that Chernabog was originally going to be the final boss, as he was supposed to be the source of all of the Heartless. Unfortunately, having a Sepheroth proxy seemed cooler, so Ansem's battles where put in. That's why they're so relatively easy compared to his battle.

* ''VideoGame/ChronoCross'' and the Time Devourer. Sure, Lavos is mentioned a couple times in passing ''if'' you go out of your way to read side documents near the end. Schala isn't. But the game already gave two 'final' bosses before this, one at the end of a long dungeon and the prior requiring a long attunement and the entire game having built up to it. But then you fight this giant space eating glowing thing that merged with Schala somehow and defeat it with ThePowerOfRock? What the hell? Dropping Magus in would have made about as much sense. Hell, Chrono, Marle and a zombie Lucca would have made about as much sense. And what was with Miguel? ''Why was he a superpowered philosophical fisherman?''

* The roaming legendaries in ''Franchise/{{Pokemon}}'', once unlocked, can be found absolutely anywhere in the world and change location at random. You're just sitting there, training up your Golbat whe. - HOLY CRAP! A RAIKOU!

** In the original games, Moltres also qualifies. His Ice and Lightning counterparts are found at the end of optional Ice and Lightning dungeons. Naturally, you'd expect find Moltres, the fire bird, in some kind of fire-themed area. Then you find him standing around in a dead end of the underground tunnel leading to the last bosses. He was relocated to a less bizarre area in the remakes.

* In ''VideoGame/{{Okami}}'' after a long an winding story based on Eastern mythology and presented in a heavily stylized watercolor graphics evoking old Japanese prints. During the game you battle shadow demons, multi-headed dragons, and Tengu to finally reach the final boss: A black whale-like fetus in a glass orb driving around a glowing technological ball-shaped mecha in the heart of a star ship. The idea may have been to give Yami a sense of [[OutsideContextVillain wrongness]] compared to the rest of the world, but it still comes out of nowhere.
* Erebus, the final boss of ''[[VideoGame/{{Persona3}} Persona 3: The Answer]]''. It ''was'' mentioned in the first game that [[spoiler: Nyx, the BigBad, was being called into existence by the despair and depression of humanity]], but the player was probably not expecting that [[spoiler: those emotions would take the form of a giant, two-headed...thing made of shadow]]. For that matter, the main game's BigBad was also kind of an example, being revealed after 80% of the game was over and never explained beyond wanting to bring about TheEndOfTheWorldAsWeKnowIt.

*** Of course, Persona 4's True Final Boss is the answer to the first question the player likely ever had. "Why do I suddenly have the power of Persona?" Thematically, that the player stopped caring after the first few minutes makes it the ultimate expression of the "Fog of Truth" - the question that cannot be seen.
* In ''VideoGame/DarkCloud 2'' (Or ''Dark Chronicle'') the final boss of the game, at the end of a bonus dungeon, is the BigBad (for no reason) from the previous game.

* The original ''DotHack'' games were actually decent about its Giant Space Fleas. All the 8 Phases of Morgana may have looked bizarre - as BlackRose was oft to point out - but there was a point where that was expected. Even Cubia was given ample foreshadowing, although his initial appearance at the end of the first game certainly may have been a surprise.
** The [[DotHackGUGames .hack//G.U.]] games each play out by introducing successive Space Fleas at the end of each game: the first game ended with a surprise AIDA infection after a battle with Tri-Edge [[spoiler:actually, Azure Kite]]; the second game ended with [[spoiler:Tri-Edge being revealed as the monster hiding in Ovan's arm]], hitherto [[spoiler:thought to be where Corbenik was hiding]]; then, suddenly, in the last game, [[spoiler: Cubia appears]].
*** [[spoiler:Cubia]] was mentioned in the G.U. Terminal Disc that came with ''Rebirth''. In a very usual [[AllThereInTheManual hackish way]] it had not been entirely forgotten.

* ''VideoGame/UltimaIII'' has one in the form of Exodus; not a traditional boss fight to end the game with, but instead, in the midst of a medieval fantasy setting: [[spoiler: a computer into which you must insert four punchcards in the proper order]]. Not exactly what you were expecting, after the first two games, but paved the way for the last-boss-less sequels.
* Armageddemon shows up in ''DigimonWorld3'' just before you get to fight the BigBad. Every other Digimon boss is foreshadowed by having an overworld sprite; he doesn't. It's debatable whether he's supposed to be a ''boss'' - the random battle theme is used and it's possible to run from him. [[spoiler:He's also one of three old bosses featured in the final boss battle]].

* ''[[BaldursGate Baldur's Gate 2]]'' had the Twisted Rune. Originally intended as the [[TheManBehindTheMan hidden cabal]] behind several sidequests, including the Athkatla slaver ring and the serial-killing tailor, the actual breadcrumb trail that was to lead to them ended up as cut content. They remained in, however, peacefully chilling in their evil clubhouse under the docks district unless the player randomly stumbled across the entrance, resulting in being dropped straight into a battle with an [[CosmopolitanCouncil eclectic]] bunch of [[BonusBoss obscenely overpowered spellcasters]] after trying to enter an ordinary looking house.

** Interestingly enough, the previous game in the Golden Sun series, ''VideoGame/GoldenSun: The Lost Age'', actually ''subverts'' this trope. At the end of the game, the main characters appear to be unhindered as they achieve their goal. Suddenly, the Wise One, a character that [[ChekhovsGunman appeared very early on in the first game but was seemingly forgotten about until the very end,]] appears and summons a three-headed dragon to combat the characters. At this point, almost every playable character responds similar to the player himself would at this point, pointing out that it's kind of odd that a being with god-like powers would do something as weird as summon a dragon to fight the protagonists, especially considering (which the characters actually point out,) they've already defeated a two headed dragon in the last game. All the characters respond this way...except for token [[TheObiWan Wise old master]] Kraden. [[spoiler: He realizes that nothing from a being called the Wise One could possibly be that simple, and, [[GenreSavvy realizing that every major dragon they fought in the series was someone transformed,]] realizes that the three-headed dragon was actually the main characters' missing parents fused together. He tries to warn the characters, but is unable to before they defeat the dragon, fatally wounding their parents in the process. Whoops.]]
* ''VideoGame/BraveSoul'' has two. One is a giant flying goldfish, although it gets a pass since it's found in some sunken ruins, and most of the monsters in the game look pretty weird anyway. The other however is a giant beetle, found in a Dragon's cave, and can't even be fought during the first visit, because of a scripted event triggered by the associated quest taking over control and moving the player directly to the destination. The only reason it was even included was because one of the developers already made it.

* ''VideoGame/DragonAgeII'' has The Ancient Rock Wraith, the final boss of the first act. While there is a lore explanation for it(it's the spirit of a dwarf too evil to return to the Stone), it's only revealed after the battle.

* The ''[[{{Strikers 1945}} Strikers]]'' series (1945, 1945II, and 1945III/1999) lives on this trope. The attract screen and the PS1 version opening doesn't hint any [[spoiler:HumongousMecha forms of whatever boss fortress you face and an alien entity as the final bosses]]. Instead, the attract screens and intros shown a WWII themed shmup.
* ''AeroFighters'' has an alien entity, a giant skinless apeman break off a jar as the final boss, the second game has you fought a black eyeball that resembles Buckbaird at the end, or a BedsheetGhost, which is randomly selected. Finally, at the third game, if you proceed good, you either fought a mutant ghost submarine in Bermuda Triangle, or goes off to space and fought an UFO in another route. Done badly, and you'll fight a joke cartoon thing instead. And the rest of the game is you fought various modern-day ([[SchizoTech sometimes future]], however) war machines with a jetfighter (except the third). Oh, did i mention that either you go into space, a temple, or underwater in the final stages?
* In ''VideoGame/{{Touhou}}'', the EX stage of ''Lotus Land Story'' has Reimu and Marisa wandering through a dream world, uncertain how they even got there. Cue getting randomly jumped by the ''creator of that world'' in the guise of a {{Meido}}...and, once you've trounced her, her ''[[StrongerSibling big sister]]'' shows up.

** More likely, given Jitterbug's motivations [[spoiler: to return to Earth]], Tyrannosatan is the force behind the demonic invasion that came through said portal before him.

* As depicted above, ''VideoGame/{{Growl}}'' is all about beating to death hordes of poachers and freeing captive animals. When you take out their leader (a masked freak with enough strength to throw a tank) his corpse begins to slither around the arena, when suddenly [[BodyHorror a millipede bursts out of its back]] and states that ''it'' is the true leader of the poachers. (Players of the ''VideoGame/{{Darius}}'' games will recognize it as [[OutsideContextVillain one of the aliens from those games]], but there were barely any hints that ''Growl'' shared a universe with them.)
* The arcade version of ''VideoGame/DoubleDragon II: The Revenge'' took a turn to the occult for some of its enemy characters. The first boss, Burnov, is a masked wrestler who, instead of blinking into non-existence like all the other defeated enemies, he will stand up and yell with his arms raised and then vanish into thin air, leaving behind his clothes and mask. In later encounters, he will rematerialize after using his death animation once. Later in the final stage, after defeating Machine Gun Willy, the game seems to be over until the player's own shadow starts gaining a life of its own and attacks the player as the actual final boss.

* When TheSimpsons got their own BeatEmUp arcade game made by Konami, there was only the first season to draw material from. Thus, we got such surreal bosses as an unnamed professional wrestler, a Krusty The Clown parade float piloted by Mr. Smithers, [[ThoseTwoBadGuys two mobsters]] who copied the two-player combination attacks, A Cerny-esque fire-breathing giant hiding in Moe's Tavern, a {{bear|sAreBadNews}}, an anthropomorphic bowling ball conjured by [[BattleInTheCenterOfTheMind Homer's imagination]], and a Noh Theater actor with a BladeOnAStick.

* ''[[CapcomVsWhatever Marvel Super Heroes Versus Street Fighter]]'': The seventh round is Apocalypse, fair enough, he's a significant Marvel villain...and then, [[MemeticMutation Suddenly, Cyber-Akuma]]!
** Akuma similarly comes from nowhere to face you in Puzzle Fighter (then again, the boss you were "[[BaitAndSwitchBoss supposed]]" to fight is [[JokeCharacter Dan Hibiki]])

*** After the boss battle, do they talk about their achievement? No, they do a completely different task, ''[[BigLippedAlligatorMoment and they never mention fighting Yami again]]''

* The final boss in ''VideoGame/{{Tekken}} Tag Tournament'' is Unknown: a woman whose actions are controlled like a puppet by a forest spirit--which looks like a werewolf's torso--floating behind her. It probably helps that the game is non-canon, but she/they still come out of nowhere.
** Tag Tournament 2 has Unknown return, but is less [[BuffySpeak Space Flea-y]], because the game confirms the EpilepticTrees floating around about it being Jun Kazama. Also, as a ContinuityNod to Unknowns' own ending from the first, the wolf thingie is gone.

** In Drak'Tharon Keep, the players fight a skeletal wind serpent named Tharon'ja. It's unclear whether this is supposed to be a spirit that the trolls worship, or troll that ate its god like the trolls of Gundrak did.

*** [[EldritchLocation Karazhan is the only place they can do ]]''[[EldritchLocation anything with at all]]''. It reaches into the Twisting Nether and thus can be used to try and invade Azeroth. In fact, it's been hinted that Karazhan was relatively quiet up until Malchezaar appeared and started stirring up the spirits.

* The boss of the Sandopolis Zone Act 1 from the SonicTheHedgehog game ''Sonic and Knuckles''. All of the other bosses in the game (and in fact most other sonic games) are either Robotnik or his robotic henchmen. And then at the end of Sandopolis we get this big huge...golem thingy that you have to trick into the nearby quicksand pit. Yeah.

* [[spoiler: Heinrich]] from ''VideoGame/ConkersBadFurDay''. Up until this point the BigBad had been the Panther King. You're all ready to fight him and [[spoiler:a xenomorph implanted by his [[TheDragon mad scientist right hand man]] pops out of his chest and becomes the FinalBoss. Yes, [[Franchise/{{Alien}} THAT xenomorph]].]]
* ''PunchOut (Wii)'' has one when you get to fight a hidden boxer. [[spoiler: Franchise/DonkeyKong. Yes, the same Donkey Kong who beats up Kremlings and plays with Mario in sports and go-karting. He has no relations to the Punch Out franchise at all...unless you've played the old arcade version and seen TheCameo]]. See, sometimes there's a point!
** You want to know what the original secret character was? [[spoiler: Princess Peach. [[http://kotaku.com/5320198/punch+out-devs-talk-graphics-difficulty-nixed-princess-peach-idea No joke]].]]

** Not quite true. He is a monster from the movies...he's one of the pieces in the holographic chess game that Chewbacca plays with R2D2. Doesn't make him showing up randomly at the cantina any less flea-like.

* The ending to ''VideoGame/{{Borderlands}}''. You're all geared up to fight Commandant Steele, whose mercenaries have been making your life difficult for the last quarter of the game, when suddenly [[spoiler: a massive EldritchAbomination pops out of the vault, impales Steele and swallows her whole, and then tries to kill the player.]]

* Indy platformer ''WilliamAndSly'' has this with it's final and only boss. Okay, it is mentioned in the beginning that something strange must be going on at the storehouse. But still...the game is an hour or so of relaxing platforming in the vein of ''{{Knytt}}''. Impressive vistas, all exploration and scavenger-hunting, only a handful of not-very-threatening enemies. Then you top it off with an awkward and difficult fight against [[spoiler: a giant phantom in the shape of a cobra's head]].

*** Actually, toxic worlds can be improved - you just have to blow them up into asteroids first. This, in turn, requires giving the planet to an enemy before the game will let you target it with the planet-destroying weapon. Give to enemy -> blow up into asteroids -> convert asteroids to planet -> terraform newly non-toxic planet. Just make sure there's another planet in the system to do the "convert to planet" step from first.

* ''PuyoPuyo Fever'' has an interesting case. It isn't the boss of the game that makes sense(no, it's just a big plot hole), but the ''secret boss''; Carbuncle, who awards you for finding him with '''the hardest fight in the game series'''.

* In DanceCentral 2, the entire career mode seems to hint that the Glitterati are the final boss. However, once you beat them you're suddenly picked up by a passing airship, which reveals a mad scientist who wants to use his robots to replace all the dance crews in the city. Suddenly you have to do five dances in a row with hardly a break in between to beat them. And you have to get near-perfect scores for each one, or you lose. This boss is never even hinted at throughout the entire game until he suddenly appears to kidnap you.
* In ''VisualNovel/HatofulBoyfriend'', dating [[CloudCuckooLander Anghel]] somehow ends in a [[GenreShift turn-based JRPG battle]] against an EldritchAbomination summoned by the school doctor with dark magics. [[http://lexlee20.tumblr.com/post/23616979639/omg-himnesia Fan theories]] posit that this creature is actually Anghel's SuperpoweredEvilSide [[spoiler: and a representation of the plague the doctor implanted in Anghel]], but during a first playthrough it's pretty confusing.

** After all the strife and struggle of reaching the end of ''CastlevaniaJudgment'', the player finally faces the mastermind behind the events of the game... [[spoiler: The Time Reaper]]. Granted, he reveals that a villain from ''KidDracula'', [[spoiler:Galamoth]], had sent him from [[spoiler:[[{{Disney/Aladdin}} TEN THOUSAND YEARS]] in the future]] to the past to alter history and make him replace Dracula as the Dark Lord, but, as a Youtube contender called Quarter Guy stated in his countdown video for his 15 favorite Castlevania bosses, there was no buildup to his identity other than he was messing with the timeline, and after he is defeated, he is never brought up again (Quarter Guy even considered it a BigLippedAlligatorMoment).

* ''Videogame/AloneInTheDarkTheNewNightmare'' features a battle with a [[NightmareFuel nightmarish]] Insectoid Winged Demon from Nowhere MiniBoss in the Library.

** After all the strife and struggle of reaching the end of CastlevaniaJudgment, the player finally faces the mastermind behind the events of the game... [[spoiler: The Time Reaper]]. Granted, he reveals that a villain from CastlevaniaSymphonyoftheNight, [[spoiler:Galamoth]], had sent him from [[spoiler:[[{{Disney/Aladdin}} TEN THOUSAND YEARS]] in the future]] to the past to alter history and make him replace Dracula as the Dark Lord, but, as a Youtube contender called Quarter Guy stated in his countdown video for his 15 favorite Castlevania bosses, there was no buildup to his identity other than he was messing with the timeline, and after he is defeated, he is never brought up again (Quarter Guy even considered it a BigLippedAlligatorMoment).
