[-[[caption-width-right:350:One, two, three, four, five, s- hey! Where's our hero?]]-]

The fourth game in the long-running JRPG series ''Franchise/BreathOfFire'', released on the UsefulNotes/PlayStation in April 2000 in Japan and November 2000 for North America.

Nina, [[EverythingsBetterWithPrincesses princess of Wyndia]], departs with her childhood friend [[PettingZooPeople Cray]] to search for her lost sister Elina, who's also Cray's fiance. Along the way, they stumble upon [[HeroicMime Ryu]], who [[EasyAmnesia doesn't remember a thing]] besides his name: Not who he is, or why he's stranded and [[NakedFirstImpression stark naked]] in the middle of the desert.

Running parallel to Ryu's story is that of Fou-Lu, an [[ReallySevenHundredYearsOld ancient]] [[GodEmperor emperor]] who awakens in his burial tomb halfway across the world in the Fou Empire to reclaim the throne that he left behind 600 years ago. Unfortunately for him, those involved no longer want to give the power up to anyone, not even to an ancient god-emperor and founder of the empire.

As the story progresses and our heroes travel all over the world, it becomes clear that Ryu and Fou-Lu's destinies are intricately entwined and key to Ryu's memories.

There exists a [[Characters/BreathOfFire character sheet]] for the series. Place any character-related tropes there.

Re-released as "[=PSOne=] Classic" in August 2011.

!! Provides Examples Of:

* AdaptationDistillation: The manga adaptation, mainly because it averts the HeroicMime trope. Arguable still, something is missing in IV when it doesn't go with the [[SugarWiki/AwesomeMusic soundtracks]].
* AdaptationDyeJob: The GrandFinale in the manga, when Ryu [[spoiler: fuses with Fou-Lu, but like in the game's Good Ending he is the dominant persona; Nina remarks that his hair is now the same (color) as Fou-Lu's white, while in the game he became blond]].
* AdaptationExpansion: The manga adaptation of ''IV'', again. Arguably a case of AdaptationExpansion resulting from a double-dose of AdaptationDistillation, in fact (from both the original ''Franchise/BreathOfFire IV'' and ExpandedUniverse material from its official artbook).
* AlasPoorVillain: Assuming Fou-Lu in ''IV'' is considered a villain (as opposed to Yuna), he'd qualify in the "good ending". [[spoiler: He recognizes he was blind to the importance of humanity, and Ryu realizes all Fou-Lu wanted was to separate mortals from the gods, and always felt guilt for Mami's death.]] Of course, the manga [[spoiler: subverts this in its ThirdOptionAdaptation.]]
* AllInARow: This is how the party runs on the field map. In battle they're in triangle formation.
* AllThereInTheManual: This is pretty extensive; huge amounts of background info only appear in the artbook. [[note]] The bits not yet incorporated into other media involve who summoned Fou-Lu, clan origins, and the fact there have been literally four World Wars with no permanent armistice. [[/note]]
* AncientTomb: The Emperor's Tomb, a.k.a. the resting place of Fou-Lu for over 400 years.
* BagOfSharing: At one point the player gets to control Ershin alone, and she gets the whole inventory even though the rest of the part is out adventuring (and has access to it the moment the player retakes control of it).
** Averted with Fou-Lu's segments, where he has his own inventory. Which makes things a bit harder, since he can't buy anything and healing items are incredibly rare in his areas.
* BattleThemeMusic: Two, actually (for the Eastern and Western continents respectively).
%%* BeautifulDreamer
* {{BFS}}: Myrmidon is big already, but his sword dwarfs him. And it grows ''even bigger'' when he attacks!
* BigBad: Fou-Lu, to the party. [[spoiler: The man responsible for almost everything behind the scenes, including Elina's abduction, is actually Lord Yuna.]]
* BigDamnFireExit: Fou-Lu's escape from the burning forest.
* BigNo: [[spoiler: Cray, after seeing just what Yuna did to Elina.]]
* BilingualBonus: Names rendered in kanji were renamed to their Korean hanja readings for international versions. The puns still stay intact. Also, both the original Japanese name [[spoiler: Master]] and the DubNameChange to Ershin count (in fact, the reason for the DubNameChange was to preserve the BilingualBonus -- in another language; the original BilingualBonus was in English).
* BloodFromTheMouth: In one of the few notably controversial scenes ''not'' censored, Fou-Lu has BloodFromTheMouth in an overt bloody VomitIndiscretionShot after his [[spoiler: Hex Cannoning.]] It's implied this may be actually a bit of [[FantasticNuke Fantastic Radiation Poisoning.]]
* BodyHorror: [[spoiler: Elina]] reaches nightmarish levels. [[spoiler: She is kidnapped, turned into an artificial endless by Yuna, and used as the engine for the Hex Cannon.]]
* BonusBoss: Angler, a mutated fish monster in North Chamba. It is far from the most difficult opponent (and reveals a new fishing spot upon its defeat).
%%* BossInMookClothing: Rider.
* {{Bowdlerized}}: One of the most infamous cases (if not ''the'' most infamous) in the series. The largely unnecessary changes include:
** Several scenes were completely removed from the North American version: one where Ursula drops her pants to prove she's a woman, a scene in which [[spoiler: Fou-Lu decapitates Soniel -- which ''itself'' was only shown in Japan via a GoryDiscretionShot/black-on-red ShadowDiscretionShot]], a filler scene where Ryu [[AccidentalPervert spies on the girls while they bathe]], and another where he accidentally grabs Ursula's breast.
** Scias is a literal DrunkenMaster in the original Japanese game, changed to a severe stuttering problem in the English localization.
** Fou-Lu's Serpent dragon form from "Hellblizzard" (Japanese) to "Waterspout" (international). Explicitly bowdlerized because of the use of the word "hell". In fact, practically every spell, weapon or ability with the words "Death" or "Hell" or making reference to demon names was changed in the international localization.
** The massive incidents of bowdlerization in the international version of ''IV'' are particularly puzzling (regarding Scias and the AbortedArc Via Censorship), considering the game was released for a platform specifically known for being friendly to controversial games.[[note]] At the time ''IV'' was released on the UsefulNotes/PlayStation, there had already been a number of considerably more violent and bloody (and controversial) games that saw print; also, Sony was explicitly promoting itself to developers that, unlike Nintendo, it did ''not'' have restrictive "morality rules" on content [[/note]] Worse yet, no other games have similarly been censored (save for Cupid's sex change); most infamously, ''II'' got away with practically ''everything'' that was censored in ''IV''. In other words, there really is no logical reason why it went through a Nintendo-esque hack job (not even fear of an "M" rating from ratings boards).
* BrokenBridge: The crater that stops you from heading back to Cray and the wrecked Sandflier, the Dam and many other things. They end up becoming unbroken later though.
%%* BubblegloopSwamp
* TheCameo:
** Momo and Bunyan from ''VideoGame/BreathOfFireIII'' show up as masters.
** Rei and Teepo (also from ''III'') appear as storeowners.
* CantDropTheHero: Subverted. While Ryu ''does'' have to remain in your party while moving around outside of battle, you're not required to use him in battle once you've got more than 3 characters in your party.
* CastFromHitPoints: The "Blitz" skill consumes 25% of the user's current HP to inflict damage. The "Disembowel" and "Deathbringer" skills cost 10% of the user's ''maximum'' HP, even [[UselessUsefulSpell when they fail to work]]. (Maximum HP can be restored, but only at a ''genuine'' TraumaInn; resting at camp won't do.)
* ChainOfDeals: Various characters will exchange "Ball" items (Lead Ball, Copper Ball, etc.) throughout the game. This becomes useful when apprenticing under Marlok, who rewards the player with new skills depending on which ball the player has acquired.
* ComicBookAdaptation: Of note, the sole Franchise/BreathOfFire-related ComicBookAdaptation ever licensed outside of Japan (in Cantonese, French, and Italian though not yet in English).
* CombinationAttack: Combining certain elements together when using combos creates a combo only spell depending on the level of the spells used.
* TheComputerIsACheatingBastard: The player party has to do combos to use certain most magic, the enemy never has to and can use it from the get go.
* ConLang: The [[http://www.gamefaqs.com/console/psx/file/196818/15263 PabPab language]] in ''IV'' (which is also used as a CypherLanguage in a sub-plot).
** Per [[WordOfGod Word of Capcom]] the [=PabPab=] language is largely comprised of combinations of English prefixes and Japanese suffixes -- thus counting as a potential BilingualBonus for speakers of both English and Japanese.
%%* ConvectionSchmonvection
* ConspicuousCG: Most enemies are sprite-based, but some of the bosses use 3D models.
* CooldownHug:
** Nina to [[spoiler: Ryu during his UnstoppableRage.]]
** A straight (if mild) example earlier with Fou-Lu and Mami in the same game, a bit more explicitly in the manga. [[spoiler: Fou-Lu tells of his past and starts to go into a rant on how meeting the wishes of mortals is impossible -- and Mami tells him she's clueless about this but can't stand to see him sad. Cue CooldownHug and FadeToBlack in the game, CooldownHug and scene change in the manga.]]
* CrapsackWorld: Thanks to the Forever War that's currently in a truce, everyone's pretty miserable, the Empire hexed quite a few locations with the Carronade which are still being fixed or only just finished being fixed and almost every town you go to has a lot of visible wear and tear on it. In short, there isn't anywhere that's really all that happy.
* CreepyCockroach: Giant roaches appear as enemies in the early and middle game. The fact that they are drawn more realistically than in the previous games make them a little bit unsettling.
* {{Cthulhumanoid}}: The octopus-headed wizards Bollor and its PaletteSwap Rollob (or is it the other way around?) in Fane of the Sea God.
* CurbStompBattle: One mid-game boss, "Ight", feels like a HopelessBossFight, unleashing powerful attacks that can [[TotalPartyKill wipe the floor]] with you in a single turn. But the moment Ryu is knocked out, he instead transforms into [[EleventhHourSuperpower the Kaiser dragon]], and kills the boss in two turns flat. In other words, both sides took a curb-stomping in the '''same fight'''.
** Any monster that comes up against Fou-Lu in a random battle will most likely experience this. Even giant dinosaurs are a very minor inconvenience.
* DeadHatShot: [[spoiler: How Fou-Lu discovered that Mami was the [[HumanResources human ammo]] in the [[FantasticNuke Carronade]] -- specifically by seeing her hair-bells fall out of the sky shortly after he himself had been Hex Nuked. Quite possibly one of the most tragic DeadHatShot moments depicted, in fact, because it's ''also'' the point Fou-Lu goes WoobieDestroyerOfWorlds and decides HumansAreTheRealMonsters.]] And yes, the manga turns it up to a ''major'' TearJerker that involves ''Ryu'' as well.
%%* DeathMountain: Mt. Giga.
* DerelictGraveyard: Sandflier Valley is obviously a valley filled with wrecks of Sandfliers.
* DespairEventHorizon: [[spoiler: Mami's death is the DespairEventHorizon that throws Fou-Lu to being a full-blown WoobieDestroyerOfWorlds; the death of the Chek summoners is the DespairEventHorizon that throws Ryu into a HeroicBSOD that unleashes the Kaiser Dragon.]]
** In the manga adaptation [[spoiler: this is ''especially'' brought home; Mami's death ends up a DespairEventHorizon twice for Fou-Lu, and after Ryu's [[UnstoppableRage Kaiser Dragon RAGE]] he literally breaks down sobbing in Nina's arms asking why [[HumansAreTheRealMonsters Humans Are Cruel to Each Other]]. Elina's MercyKilling is especially'portrayed as a DespairEventHorizon for Cray and Nina as well (the latter being shellshocked, the former nearly suffering a HeroicBSOD himself).]]
* DownTheDrain: The party infiltrates an Imperial base via aqueduct, which the Empire normally uses to keep the Carronade from overheating when fired.
* DragonsAreDivine: The dragons are essentially immortal gods, which were summoned by mortals to act as the world's protectors.
* DragonsUpTheYinYang: Dragons ''are'' the [=YinYang=]. Literally.
** This is not counting the "Static Heaven" ''bagua'' in the final stage, nor is this counting designs in Fou-Lu's clothing. Suffice it to say that ''IV'' is about as subtle as a brick with this trope.
* DramaticWind: Various characters' battle sprites, including their victory animations.
* DreamLand: Fairy Village resides here. Also the Deis' dream levels.
* DubNameChange: From Master to Ershin (to preserve a BilingualBonus).
** Literally ''all'' of the [=NPC=] dragons [[spoiler: with the exception of Deis]] also suffer this (in an unusual variation in which the DubNameChange consisted of changing their names to Koreanisations of what type of dragon they were).
* DuelBoss:
** Nina vs. Joh early in the game.
** Every boss fight which Fou-Lu fights.
** And the short battle between Ryu and Fou-Lu during the game's climax.
* ElementalEmbodiment: Two bosses in the game are elemental creatures that came to life when they absorbed the power of a god. One is a golem that lives by the sea, another dwells in a volcano.
* TheEmpire: The Fou-Lu Empire, created by the God Emperor Fou-Lu some 400 years ago, which has been in a ForeverWar with the eastern continent which has multiple nations on it.
* EverythingsBetterWithPlatypi: The Cap enemies which appear frequently in the early parts of the game.
* EvilWeapon: The Hex Cannon/Carronade. Even as it annihilates the souls of the unfortunate persons used as ammo (who are, of note, literally ''tortured to insanity'' first) and corrupts the targeted land and persons, it empowers and simultaneously corrupts those who use it. It's also a literal FantasticNuke.
* ExpositionCut: Pretty much constant in the first section. Nina explains the situation established in the opening cutscene to Ryu when they seek shelter in a cave for the night using this trope, then they explain things in the same way to Cray when they return to the crash site, then they explain things to the Woren elders when [[spoiler: Cray is arrested.]]
* FantasticNuke: The Empire's Hex Cannon, or Carronade. It is [[WordOfGod explicitly]] powered by a "sacrifice", using [[spoiler: all the nightmares, terrors, and fears of a person ''tortured to insanity'']] as ammunition.
** The city of Synesta is said to be (mostly) purified of the magical radiation by the time the game begins, being seen as a rebuilt town with only a few monsters still lurking underground.
** The town of Chamba was not so lucky; a team of Purifiers (who must wear full suits of magical armor to protect them from its effects) estimate that the majority of the town will remain utterly uninhabitable for "at least a year". In other words, the player never gets to see Chamba in its proper glory.
** And then there's General Yohm's order to use the Carronade against Fou-Lu himself: The revelation that they used [[spoiler: Mami]] to power it was TheLastStraw that pushed Fou-Lu [[KillEmAll over the edge]].
* FightWoosh: Normally a blue circular swirl, but also [[ColorCodedForYourConvenience color-coded]] to indicate when one side gets a free turn at the start of battle.
* FireWaterJuxtaposition: With Fou-Lu representing water and Ryu representing fire.
* FiveManBand:
** TheHero - Ryu.
** TheLancer - Cray (Interestingly, he has the looks and abilities of TheBigGuy, but his personality fits this trope better).
** TheSmartGuy / RobotBuddy - Ershin.
** TheBigGuy - Scias (He has very few lines and no plot significance after he formally joins, serving only as an extra fighter).
** TheChick - Nina.
** SixthRanger - Ursula.
* FlyingSeaFoodSpecial: Skulfish, the first boss in the game. Flying... Flyfish are also seen above the clouds when the party visits the Wind Dragon.
* {{Foreshadowing}}: In Wychwood, some faeries attempt to play tricks on the party, resulting in one faerie receiving a headbutt from Ershin. This surprises the fairies, who claim mortals shouldn't be able to see them. [[spoiler: Ershin, we eventually learn, is indeed no mortal, but rather an Endless named Deis]].
* ForeverWar: The conflict between the Fou Empire and the Alliance in ''IV''. The two continents have been in a Cold War that has lasted 600 years, punctuated by ''four'' world wars and the incipient threat of a fifth.
* FullBoarAction: Bilbao and its ilk are huge electric boars.
* GaidenGame: Two separate sidestory games in ''IV'''s universe exist (''Breath of Fire IV - The Sword of Flame & the Magic of Wind'' and ''Breath of Fire IV: Faeries Light Key'') along with [[https://en.wikipedia.org/wiki/Mobile_phone_games_of_the_Breath_of_Fire_series two other Gaiden Games]]: A SpinOff of the fishing game from ''IV'' (''Breath of Fire: Dragon Fisherman'') and a "Great Dalmuti" / "Millionaire" / "President" / "Asshole" game featuring characters from ''IV'' (''Breath of Daifugo'').
** Unfortunately, due to the platform and carrier these were released for (Japanese smartphones using Qualcomm's BREW OS, and most of ''these'' being an exclusive to [=NTT's DoCoMo mobile phone network=]) these are, to a one, NoExportForYou and likely to remain so permanently.
** Of note, ''Breath of Daifugo'' and ''Breath Of Fire: Dragon Fisherman'' were co-releases with a ''Franchise/StreetFighter'' GaidenGame (a Solitaire port) and the BREW-phone version of ''VideoGame/MegaMan2'' respectively, whilst the sidestory games were released at the same time as the ComicBookAdaptation; adverts within Comic Blade Avarus and the volumes published by Mag Garden included adverts for the Gaiden Games.
* GameplayAndStorySegregation: Despite being able to transform since shortly after being introduced, Ryu's Dragon transformations go unnoticed until Rasso comments on it to himself and then aren't noticed by the rest of the party for awhile.
** Rossu even realizes that Ryu's a Dragon if you don't use Meditate in the battle against Yoghrem on top of the tower.
** Plus the fairies even call him a Dragon and give him the nickname of Dragon Boy.
* GettingCrapPastTheRadar: Literally, when you go to get a Fairy Drop, it's pretty much stated that the Fairy Drop is actually fairy crap.
* GiantEnemyCrab: You primarily face them on the Western Continent during a part where you're trapped on an island while the tide's in and you can't get past.
* GoryDiscretionShot / ShadowDiscretionShot: [[spoiler: The Japanese PSP's depiction of Fou-Lu's decapitation of [[TheEmperor Soniel]], specifically via a "washi screen" variant showing a black-on-red silhouette.]]
** And ''this'' ended up {{Bowdlerised}} in the international version. This may well be only one of two known incidents with international adaptations where a violent scene {{Bowdlerised}} in the original via ShadowDiscretionShot was ''itself'' {{Bowdlerised}} out of existence in international adaptations. (The other incident involves dub adaptations of ''Anime/YuGiOh'' for American children's television, and at least makes ''sense'' in that context.)
** [[SubvertedTrope Subverted]] in BloodierAndGorier fashion in the manga adaptation, apparently as a very deliberate TakeThat to aforementioned censorship. (In comparison, [[spoiler: Elina's death scene]] was actually depicted ''less'' graphically in the manga.)
* GreenHillZone: The green forested areas around Ludia and Wyndia.
* GustyGlade: The caves beneath Wyndia have strong gusts of winds pushing you around.
* HeadlessHorseman: There are two of them in this game. One's called [[ExactlyWhatItSaysOnTheTin "Horseman"]], the other's called [[BossInMookClothing "Rider."]]
* HealingFactor
** An enemy called Trunked regenerates 15,000 HP ''per turn'', but is (quite fortunately) harmless, existing solely to practice combo attacks on. (Its higher-level counterpart, Trean, regenerates ''[[UpToEleven 30,000 HP per turn]]'')
** The Rider 20,000 HP per turn. It is the [[BossInMookClothing most powerful enemy in the game]].
** The Dragonne boss cannot be killed until it stops regenerating its HP.
* HeroicMime: Averted in the manga and novelization for purposes of character development.
* HiddenElfVillage: Fairy Village. It can only be found by people who the Fairies take there personally.
* HopelessBossFight: A grim variation. [[spoiler: [[WeCanRuleTogether If you take Fou-Lu's offer to merge with him]], Ryu becomes absorbed and then the Infinity Dragon is summoned to battle the rest of your party. Only here, ''you're controlling the Infinity Dragon'', leaving you with maxed stats and overpowered moves to waste your former allies with. After you're finished with them, the bad ending plays. Also subverted in that it's possible to let them defeat you via hacks, but that immediately leads to a standard GameOver, turning this whole thing into a lose-lose situation.]]
* HotBlooded: The Woren tribe. Cray tries to suppress his urges, as his position as leader requires a cool head.
* HumansAreTheRealMonsters: The various atrocities that Fou-Lu witnesses gives him this viewpoint.
* ImmortalBreaker: The Dragonslayer is the only weapon that can kill the nigh-immortal dragons. It gets used twice: once to kill Fou-Lu, and once to kill [[spoiler: Elina]].
%%* InsurmountableWaistHeightFence
* InterfaceSpoiler: Talking to your party in the camp can help give you some idea of what to do next. Doing so at one particular point, however, can spoil a major plot point: [[spoiler: Ershin's usual way of ending her statements ("...says Ershin.") instead comes out "...says Deis.")]] ''Oops.''
* InterspeciesRomance: [[spoiler: Between Cray, a Woren, aka tigerman and Elina, a Wyndian, aka birdwoman.]]
* IronButtMonkey: Kahn is a good example. He is defeated multiple times by the party, shot off of the mast of a ship by Ursula, and his lack of fighting skill is pointed out by Una and Zig's crew. He recovers quickly from each defeat, though, and can even become a master to the party later in the game. Appropriately, his special ability gives his apprentices a chance to survive fatal blows in battle.
* ItsAllUpstairsFromHere: The tower of Pung' tap, which has a dragon on top of it.
* ItemCrafting: The Blacksmith on Mt. Glom can make special armors if you bring him the materials needed to make it.
%%* ItsQuietTooQuiet
* JungleJapes: The jungle around the Pabpab village.
* KarmaHoudini: One of the game's most infamous aspects is that [[spoiler: Yuna]] who was to blame for nearly everything bad that happened, apparently was never punished. There is a bit of background behind this, which can be read in the main entry. [[note]] The long and short of it being that the game was rushed out before the ending was fully completed and the comeuppance was never shown (but was planned). However, the manga wasn't under the same constraint, and yet it still played this trope straight... [[/note]]
* KeepItForeign: The DubNameChange of Master to Ershin. [[note]] The original name was too much of a spoiler in English, so the character was renamed Ershin -- Chinese for "Two Souls" -- to preserve the PropheticName.[[/note]]
* KillTheCutie: [[spoiler: Mami. Even worse, she is captured, broken by ColdBloodedTorture, and ultimately killed by being used as HumanResources in a FantasticNuke that is PoweredByAForsakenChild (with connections to the target).]]
** The manga adaptation turns this UpToEleven in a major borderline StuffedIntoTheFridge moment. [[spoiler: Including Mami's literal last words being "An-chan", a term roughly equivalent to "dear" which she uses as an affectionate term for Fou-Lu, and the sound of her [[MementoMacGuffin hair bells]] after the Carronade fires making it very obvious what happened...]]
* KingInTheMountain: Subverted to the point of deconstruction. In essence, Fou-Lu would have been the Fou Empire's prototypical KingInTheMountain if TheEmpire had kept up its end of the bargain. Instead, Fou-Lu's entire storyline in the game can be best described as "What Happens When a Country's Government Sees the Return of Its KingInTheMountain as an UnwantedRevival". [[TimeForPlanB It goes poorly for all involved]].
* LazyBackup: You'll get GameOver when your main fighters die, even if you've extra three party members are behind you doing nothing.
* LeakedExperience: It is actually split evenly between the characters after the battle.
%%* {{Leitmotif}}
%%* LethalLavaLand: Mt. Glom.
* LiteralSplitPersonality: Ryu and Fou-Lu [[spoiler: thanks to a botched summoning by the Fou Empire's predecessor, and resulting in the god they called forth not only being split in two but the half that became Ryu being temporally displaced six hundred years in the future.]]
* LowLevelAdvantage: You'll get better stat bonuses from later Masters if you keep your levels down early in the game.
* LoveHurts:
** This is pretty much what the Hex Cannon relies on in order to inflict damage -- the closer the sacrifice that was loaded into the cannon is to the intended victim, the greater the damage it causes.
** Cray [[spoiler: spends most of the game searching for Nina's sister and his love interest, only to kill her to end her misery as she's literally one with the building the Hex Cannon is in.]]
* MagicalEye: Though not technically ''evil'' in this case, the Dragon Eyes are depicted as actual non-human, draconic eyes and the people who possess them are fated for either great good or great evil. Ryu is depicted as having PsychicPowers as a result.
** Depicted ''much'' more blatantly in the ComicBookAdaptation of ''IV'' [[spoiler: where the Dragon Eyes are explicitly depicted as HellishPupils; Fou-Lu and Deis have them constantly, and Ryu gets them when his Dragon Eye activate. This even goes to the extent of ''Rhem'' having HellishPupils when she is "ridden" / possessed by Deis, as well as an AffectionateParody in the "behind the cover" 4-koma comics included in the manga.]]
* MaximumHPReduction: If someone was downed in battle and still down at the end, they would be brought back with 1 hp and have their max health reduced. Also, both games contain a move called Disembowel which inflicts HPToOne at the cost of reducing the ''user's'' maximum HP until the next time they rest at an inn.
* MementoMacGuffin: [[spoiler: Mami's bells she wore in her hair. In fact, the very incident that causes Fou-Lu to GoMadFromTheRevelation was seeing Mami's bells fall from the sky after he was at ground zero of a Hex Cannoning.]]
** In the manga adaptation, [[spoiler: Mami's bells are a MementoMacGuffin a second time during the BattleInTheCenterOfTheMind between Fou-Lu and Ryu (leading from the BadEnding to the GoodEnding). Fou-Lu literally breaks down sobbing upon being confronted by Ryu... Whilst Ryu holds Mami's bells in his hand.]]
* MercyKill: [[spoiler: Elina pleads to Cray to end her miserable existence, and he has no choice but to comply]].
* MetalDetectorPuzzle: An early mini-game where you had to find buried parts to repair your sand-ship with. The mini-game could later be revisited to dig up various materials with which you could craft special pieces of armor for Ershin, and abusing this can lead to a DiscOneNuke for her.
* MixAndMatchCritters: The Wind Dragon which is combination of a dragon, an elephant and a whale.
** Pretty much ''all'' the [=NPC=] dragons / Endless fall into this category; [[JustifiedTrope justified]] in that each dragon is the PhysicalGod of a specific element or force.
* MookCommander: The platypus-like Wakwak enemies would sometimes space out and do nothing, but another type of Wakwak could command the grunts to attack you, with the "Command" skill. Even with it, Wakwaks are basically still Goombas. The skill itself could also be used to counter "confused" status.
* MyGreatestFailure:
** Cray: [[spoiler: Being unable to return Elina to Wyndia, and in fact being forced to [[MercyKill euthanise her]] after she is turned into an artificial Endless.]] This would also apply to Nina as well.
** Ryu: [[spoiler: Being unable to stop the people of Chek from being massacred. This causes a HeroicBSOD which unleashes the Kaiser Dragon.]]
** Fou-Lu three times over: The first in realising the purpose for which he was summoned was impossible due to the [[InYourNatureToDestroyYourselves intrinsic nature of humanity]], the second being the fact that the empire he founded has become [[TheEmpire irredeemably corrupt and overtly evil]], and the third being [[spoiler: the inability to save Mami and the knowledge [[ItsAllMyFault she was tortured and used as Fantastic Nuke Ammo because she loved him]].]] The combination is enough to make him GoMadFromTheRevelation.
* NeverGrewUp: [[spoiler: The entire town of Chek, with the possible exception of the Abbess.]]
* NiceHat: Yuna, Soniel and Fou-Lu, in a ProjectedMan when he first appears to Ryu. Depicted in the official artbook, and especially in the manga.
** The cover for Volume V of the manga has fun with this in giving [[http://i.imgur.com/PVRAjtf.gif both Fou-Lu and Ryu]] matching Nice Hats.
** All this is a remarkable example of ShownTheirWork. [[note]] As it turns out, the hats are rather similar to those worn by (in particular) Ming and Tang Dynasty Chinese court officials and Korean royal court officials. [[/note]]
* NoRomanticResolution: The manga, for all its worth in giving Ryu an actual character and [[CharacterDevelopment eventual development]], it severely tones down the one thing that it was clear in him as a HeroicMime: His interest on Nina as the game progressed. [[spoiler: The Good Ending in the game made him come back after sending The Endless back to their world solely for his love for Nina, the manga however, doesn't touch upon this subject and Ryu comes back for friendship, in fact, Nina wasn't directly mentioned by him during the sequence]].
* NominalImportance: Important characters to the plot are recognizable from their in-game portraits when you talk to them.
%%* {{Novelization}}
* NowWhereWasIGoingAgain: Your party members will remind you where to go when you talk to them in a camp.
* OneSteveLimit: Deis specifically asks [[spoiler: Ershin]] to call her by her real name, instead of calling her [[spoiler: "Ershin"]].
%%* PalmtreePanic: Tidal Flats.
* PeninsulaOfPowerLeveling: Entering the Great Plains forces you to use only Ryu. In the Great Plains, there's a Temple where a lot of Nut enemies are found. Nut Enemies are weak, incredibly hard to hit, but are weak against Fire Spells. The Burn spell costs 1 AP and is capable of killing most of them with 1 shot. Since Ryu is by himself, he gains far more XP per battle than is possible for a very long time with a full party since XP is split by the number of people traveling with you normally. Sadly, only Ryu can be leveled this way.
* PhysicalGod: Fou-Lu, [[spoiler: the other dragons, and Ryu]].
%%* PortTown: Shikk.
* PowerCopying: How you learn most of the customizable skills that you can't learn from Masters. Party members defend and once the enemy uses it and a party member gets an ! above their head, they learn the skill.
* PowerfulButInaccurate: Ershin's Risky Shot guarantees a critical hit if it connects, but only has 40% accuracy.
** The Master Una grants this as a passive trait thanks to her Will ability ''Wild''; anyone apprenticed to her will hit harder but less often.
* PreAssKickingOneLiner: Scias if his health gets dropped to critical and he actives his GlassCannon mode.
-->'''Scias''': You will feel my blade...
* AProtagonistIsRyu: He's even named Ryu, like the rest of the Breath of Fire protagonists.
* RealSongThemeTune: Elina's theme, [[spoiler: "Pavane for a Dead Princess"]], is in fact a version of the classical piano piece ''[[https://en.wikipedia.org/wiki/Pavane_pour_une_infante_d%C3%A9funte Pavane pour une infante défunte]]''[[spoiler:[[note]]In french, "Pavane for a Dead [[DeathOfAChild Child]]"[[/note]]]] by Maurice Ravel.
%%* RedEyesTakeWarning
* [[RedOniBlueOni Red Dragon Blue Dragon]]: Played ''very'' straight with Ryu and Fou-Lu.
* RoyalWe: Used by the Emperor Soniel of Hesperia, as appropriate. Also by Fou-Lu, though for him it's partially justified in that [[spoiler: his soul is split in two, the other half being Ryu, so he's sort of two people at once.]]
* SandBridgeAtLowTide: Done backwards, our heroes walk onto Saldine island, then find themselves stranded at high tide.
* SaveThePrincess: Deconstructed, rather harshly. [[spoiler: When you finally find the princess, she's far beyond saving...]]
* ScaryScorpions: Scorpions are early game monsters encountered in the desert around Sarai and they're huge.
* SealedGoodInACan: [[spoiler: Deis trapped in Ershin's armor.]]
* ShamefulShrinking: Some of the cast attempt to hijack a vehicle (long story). The merchant who owned it gave them a dressing down (before deciding to lend them the money to buy their own), causing the members of the party who did it to shrink.
* ShiftingSandLand: Your starting point.
* ShipTease: The manga adaptation has this in spades (not surprisingly, seeing as it was in a manga magazine geared towards young adult women), particularly regarding [[spoiler: Fou-Lu x Mami]].
* SlidingScaleOfAnthropomorphism: Plenty of the game's population.
** Wyndians (like Nina) are {{Winged Humanoid}}s.
** Manillo are FishPeople.
** Scias, as well as several canine [=NPCs=] (like Rwolf), are PettingZooPeople.
** Ursula, Lord Yuna, and the Woren are a LittleBitBeastly.
* SlippySlideyIceWorld: Ice Peak and its surroundings.
* SplitPersonalityMerge: Happens no matter [[MultipleEndings which end-game you pick]]; it's just a matter of whether you decide that HumansAreTheRealMonsters.
%%* SpritePolygonMix
%%* StarfishCharacter: Ryu and Fou-Lu.
* StoneWall: Two types of enemies found at the Abandoned Village, the Trunked and the Trean, have a TON of HP and defenses and HP regeneration, but will not attack the party. The perfect punching bags for practicing Combos.
* SwordOfPlotAdvancement: The Dragonslayer. A certain part [[spoiler: near the end of Act 3]] required the group to find and use it.
* ThirdOptionAdaptation: The manga's rendition of the good and bad endings.
* ThirdPersonPerson: Ershin. This becomes [[JustifiedTrope justified]] once it is [[TheReveal revealed]] who "Ershin" really is. [[spoiler: "Ershin" is what the suit of armor calls Deis.]]
* TitleDrop: The manga's long ''Utsurowazarumono - Breath of Fire IV'' title, Utsurowazarumono can be translated as ''The Endless'' or ''The Unfading Ones'', so anytime Ryu, Fou-Lu and the other Endless are mentioned in story it also doubles as this.
* TooGoodForThisSinfulEarth: [[spoiler: Princess Elina, who pretty much devoted her life to finding a way to end the war and promote peaceful coexistence between the continents, and consequently, was well loved by the people in the east. She was chosen by Yuna as a sacrifice ''because of this.'']]
* TragicKeepsake: [[spoiler: Mami's bells]] in both the game and the ComicBookAdaptation.
** The ComicBookAdaptation actually manages to elevate [[spoiler: Mami's bells]] to a frank CradleOfLoneliness. [[spoiler: In Chapter 19, Fou-Lu is depicted cradling Mami's bells whilst [[TechnicallyASmile giving a very feral smile]]; in Chapter 25, Ryu even points out that Mami's bells have become Fou-Lu's "most treasured possession", which begins the progression from the Bad Ending to the Good Ending.]]
* TrappedInAnotherWorld: Occurs in spades and is arguably a major theme of the game with the Endless, who were [[spoiler: summoned to this world against their will. The dragon gods have accepted their lot in life, the others are not that pleased.]]
* TraumaCongaLine: Poor Fou-Lu... First, the Empire doesn't want him to reclaim his throne, so they send General Yohm to pursue and kill him. Repeatedly. A cute boar he befriends makes a sacrifice of itself to open an escape path for him, while the only person in the world he may have had any love for is taken prisoner by Imperial forces, [[spoiler: then tortured and used as living ammunition for the Carronade]], before Fou takes a ''direct hit'' from the Empire's magical superweapon. No wonder he wants to KillEmAll.
* TraumaticSuperpowerAwakening: Ryu gains the ability to transform into a dragon early on in the game, but it takes him seeing Captain Rasso massacre a village full of innocents (and forcing him to duel with a monster shortly afterwards) for him to unlock the more powerful transformation.
* TreeTopTown: The Pabpab village resides in trees, since its in middle of a swamp.
* TwinTelepathy: Ryu and Fou-Lu are implied to have this to a limited extent in ''IV'' (though for the most part this is only explicitly noted at the game's end).
** ''Very explicitly depicted'' in the ComicBookAdaptation of ''IV''; in fact, it's actually a major plot-driving force in the manga.
* UndergroundLevel: There are heaps of these.
* UnusuallyUninterestingSight: Both played straight and subverted:
** Fou-Lu in Sonne, who is portrayed by Mami as her brain-injured cousin Ryong. No matter her cousin has horns in one of the few towns in the game not comprised of PettingZooPeople. The landlord is in fact the only one who mentions something amiss.
** Played straight and subverting the prior occurrence at the same time when Ryu returns to Sonne later in the game, where Ryu is greeted as if he were the missing "Ryong", despite the fact Ryu has blue hair and no horns and a definite lack of YeOldeButcheredeEnglishe. Either Sonne is a village full of psychic farmers, or they possess ridiculously strong facial recognition abilities (in the artwork Ryu and Fou-Lu share the same face, but this is hard to see since they have vastly different expressions and features).
* UnwantedRevival: Fou-Lu. Though technically he never died (he's immortal), [[TheDragon General Yohm]] explicitly states upon first meeting him that the Empire finds his resurrection "inconvenient" and that they'd rather him "rest a little longer" in his tomb.
* UselessUsefulSpell: Quite a few of them, not counting the ones that are ''literally'' useless to begin with (like "Distract" or "Feign Swing").
* WhenTreesAttack: There's monster trees as a random encounter and if you attack them with fire, they become even more dangerous to fight.
* [[WhyDidItHaveToBeSnakes Why Did It Have to Be SEA LICE AIEEEEEE]]: Ursula in a particularly [[SugarWiki/FunnyMoments hilarious]] scene wherein she and Nina [[WhatDoTheyFearEpisode are discussing phobias]]. It turns out Ursula is ''extremely'' phobic of bugs... Even sea lice, which are completely ''harmless'' bugs (merely seeing one is enough to cause Ursula, normally quite the Type A {{Tsundere}}, to [[ScreamsLikeALittleGirl scream like a cheerleader]]).
* WombLevel: The path leading to [[spoiler: Princess Elina]].
* {{Wutai}}: The continent of Hesperia is based on Asian cultures.
* YeOldeButcheredeEnglishe: Fou-Lu constantly speaks in this manner in conjunction with the RoyalWe.
** In a backhanded salute to this, the manga adaptation of ''IV'' apparently has Fou-Lu speaking in what amounts to Ye Olde Butcherede Japanese, as opposed to the original {{Keigo}}.
