[[caption-width-right:240:Asha, protagonist of ''Monster World IV'']]
''Monster World IV'' is the sixth installment in the ''Franchise/WonderBoy'' franchise, and the last one to be released before the franchise's 20 years long break. The player controls Asha, a young girl who embarks on a journey to help out spirits calling for her, and is accompanied by an amorphous RidiculouslyCuteCritter known as a Pepelogoo and a disgruntled genie who escorts Asha to the Kingdom of Rapadagna. Notable for being the only "Monster World" game without a male protagonist and thus was released without the usual "Wonder Boy" branding.

Originally released for the [[UsefulNotes/SegaGenesis Mega Drive]] on April 1994, ''Monster World IV'' remained exclusive to the Japanese market until Sega released an English-language version of the game for the UsefulNotes/{{Wii}} UsefulNotes/VirtualConsole, UsefulNotes/PlayStationNetwork and UsefulNotes/XboxLiveArcade (the XBLA release is part of ''Sega Vintage Collection: Monster World'' along with the original versions (in Japanese and English) of ''[[VideoGame/WonderBoyInMonsterLand Wonder Boy: Monster Land]]'' and ''[[VideoGame/WonderBoyInMonsterWorld Wonder Boy in Monster World]]'') in May 2012.
----
!!Tropes in ''Monster World IV'':
* ArabianNightsDays: The game's setting style, in a departure from the MiddleAges setting from the other games. Examples of this include:
** A genie
** [[SinisterScimitar Scimitars]]
** A magic carpet
** A merchant who uses a camel
** A Taj Mahal-esque palace
** Caravans
** And some of the music is done in an Arabic-style.
* AutoRevive: If Asha has both a Healing Medicine and Pepelogoo with her when she dies, the Pepelogoo will automatically use the medicine on her, reviving her on the spot.
* BackFromTheDead: Three examples: 1) [[spoiler:Pepe]] returns to help you during the final battle. 2) The final boss, Fear Incarnate, is [[spoiler:Biomeka]] from ''Wonder Boy in Monster World''. 3) [[spoiler:Pepe]] is revived again during the ending credits by Asha.
* BadassAdorable: Asha fits this trope to a T. Not only does she go out and fight against the evil threatening the world. She is also the one to finally put an end to [[spoiler:Biomeka]]. All that while looking so cute and childlike at the same time!
* BadassBoast: Fear Incarnate gives "I am forever!" as his final boast before the boss battle.
* BadassCape: Asha gets a pretty impressing one from the Queen after defeating Evil Incarnate, complete with shoulderpads of doom.
* BedsheetGhost: Appear as enemies in Handera Volcano.
* BeneathTheEarth: The setting of TheVeryDefinitelyFinalDungeon.
* BigBad: Fear Incarnate. [[spoiler:Who is actually Biomeka.]]
* BigDamnHeroes: [[spoiler:A fully grown Pepe gets to be the hero twice]].
* BookDumb: Slightly implied with Asha, who considers almost every book in Rapadagna palace library boring or impossible to read. This even includes a book about the Magic of Eleanora (the same magic Shion used) thus probably explaining her lack of magic abilities besides the magical hit.
* BrainwashedAndCrazy: The Queen, and also the citizens to a minor extent.
* BreakingTheFourthWall:
** One of Rapadagna Palace Guards comment on how silly it is how some videogame characters like him always repeat the same lines.
** On your first visit to the Kingdom of Rapadagna, one of the townspeople who tells you about the monsters that are multiplying as of late will also say "People always say stuff like that in [=RPGs=]."
* CallBack:
** The four elemental spirits are actually Shion's temporary sidekicks from the previous game.
** One of the books in the Royal Library is called ''Magic of Eleanora'', Eleanora being the fairy queen from the previous game.
** Shion himself is mentioned in one of the books. [[spoiler:Unfortunately, it's not good news: a hole suddenly appeared in front of his house, he disappeared and was never heard from again]]. Then again, the official 2012 English version doesn't have the bad part.
** [[spoiler:Biomeka, the villain from ''Wonder Boy in Monster World'' IS Fear Incarnate.]]
** The last stage's theme song is a sort of remix of the sky castle stage's theme of ''Wonder Boy in Monster World''.
* ChestMonster: Giant coins and giant bags of money attack you in the Sky Castle.
* TheChosenOne: It's written in the books of the library that there is one, and it's obviously Asha. Biomeka realizes this far too late.
* CollisionDamage: Averted with most enemies (the ones that do hurt you are the ones that look painful, like the ones that are [[IncendiaryExponent on fire]]), despite being played straight in the rest of the series.
* ContinuityNod: The aforementioned final boss. Also, the four spirits you rescue are Shion's companions from ''Wonder Boy in Monster World''.
* CreepyCentipedes: The Tower of Silence has an Oomukade as the boss. She's a WarmUpBoss, as she only has one attack and goes down with a dozen stabs.
* CriticalHit: Some swords have a 20% chance of landing "Magical Hits", which will deal more damage than a normal strike.
* TheCuckoolanderWasRight: [[spoiler:The crazy old woman walking around with a pan on her head, telling you the Pepelogoos are harbingers of doom and despair is completely correct.]]
* CuteIsEvil: [[spoiler:The yellow Pepelogoos turn out to be malevolent little critters whom Fear Incarnate and the Wizards are using to emotionally control the inhabitants of the town.]]
* DarkestHour: [[spoiler:After the yellow Pepelogoos reveal themselves, possessing everbody, the background music in town switches to an ominous tune. The villagers are apathetic and some are very rude to you (including the rich lady, who won't buy gold bars from you) and the armor merchant is no longer there. On top of that, the previously nice queen is going mad with power, and after confronting her, Pepe nearly dies and can't follow you anymore]].
* DemBones: Skeleton fencers who show up in the Sky Castle.
* DoubleJump: A rare justified example--Asha can hold onto Pepe as she jumps, then leap off Pepe for an extra boost.
* EggMacGuffin: The Pepelogoo egg. Asha has to find it and hatch it before she can go to Handera Volcano.
* EvilAllAlong: [[spoiler:The yellow Pepelogoos through DemonicPossession that took place well before Asha came to town.]]
* FantasyCounterpartCulture: Of AncientArabia in particular.
* FamedInStory: Shion, the protagonist from the previous game seems to be remembered by everyone as a saviour in past times.
* FlyingCarpet: Used to reach the sky dungeon.
* FrictionlessIce: Shows up in the third Ice Pyramid. Once Asha starts sliding, she can't stop unless she grabs Pepe or bounces off a wall or an enemy.
* TheGoomba: The slimes. Generic slimes are the first enemies Asha encounters, and due to the lack of CollisionDamage, they can't even hurt her. [[UndergroundMonkey More harmful variants show up later]], but they still move in the same basic pattern.
* HailfirePeaks: The Ice Pyramid is a mix of TempleOfDoom and SlippySlideyIceWorld.
* HarpingOnAboutHarpies: The bird-woman who appears as a sub-boss in the Handera Volcano stage.
* HeartContainer: Collecting 10 Life Drops will permanently increase Asha's maximum health by one heart.
* HeroicSacrifice: Done twice by [[spoiler:Pepe]]. First, he [[TakingTheBullet takes the missile]] that the possessed Queen shoots at Asha. Then, in the final battle, he blocks the boss from using his petrifying gaze, getting turned to stone himself in the process.
* HonestAxe: In the Stream Sanctuary, there's a part where you must throw a bucket in a well and then honestly tell the magician which of the buckets is yours. If you lie, [[ButThouMust you have to restart the conversation]]. If you tell the truth, you can go fight the Water Wizard.
* HopelessBossFight: Just after completing the Sky Castle/Aegis Island, Asha must encounter the brainwashed Queen again. This time there is no winning the fight as any attack you try does nothing to her and her attacks do triple damage compared to the rest of the game. It is subverted after you are down to one heart when [[spoiler:Pepe returns and sings the Cradle Song of Pepelogoo that reverses all of the corruption that occurred in the town.]]
* ImprobableWeaponUser: The Queen fights with fans. They do a lot of damage.
* InconvenientlyPlacedConveyorBelt: In the Sky Castle. They're tiny, and they move.
* IncredibleShrinkingMan: At a certain point in the Sky Castle, Asha has to enter a door that shrinks her to half her size. This has also happened to the castle's residents, and only by shrinking herself will Asha be able to hear them.
* InventoryManagementPuzzle: Asha only has room for 10 items in her pockets. This doesn't come into play until you reach the Ice Pyramid, where you must make room for each of the five statues in your inventory.
* IronButtMonkey: The Pepelogoo. During the adventure, he gets into all sorts of harmful things (like serving as a platform while in contact with lava or getting frozen) without a scratch on him.
** [[spoiler: This gets tragically subverted thanks to his HeroicSacrifice later on.]]
* LethalLavaLand: Handera Volcano.
* ALoadOfBull: The ghost-like minotaur creature who appears in the Ice Pyramid.
* LuckySeven: Acquiring exactly 777G at any point will earn you 7000G. If you're lucky to get this bonus as early as you can, then you can easily afford some good equipment early on.
* MacroZone: A portion of the Sky Castle where Asha has to shrink to proceed. Mouse enemies become much more dangerous to her, and she can't even damage the mini-boss until she returns to normal size.
* MegaNeko: [[spoiler:Pepelogoo looks like a big cat when fully grown.]]
* NotQuiteFlight: Asha can glide by holding onto Pepe in midair.
* ObviouslyEvil: The Wizards in their human forms. Scowling faces with black beards, pointy ears, EvilLaugh... Come on!
* OurGeniesAreDifferent: The Genie in this game doesn't grant any wishes, and instead serves as Asha's personal escort to the Kingdom of Rapadagna whenever needed.
* PermanentlyMissableContent: Once you clear a level, you cannot go back to it. If you missed any valuable items such as Life Drops and Gold Bars...well, you won't be able to go back for them any more.
* PopQuiz: The Sphinx, yet again, gives you one before you enter the third part of the Ice Pyramid.
* RecurringRiff: Nearly the entire soundtrack consists of rearrangements of the game's main theme.
* RidiculouslyCuteCritter: The Pepelogoo, especially Pepe.
* SeriesFauxnale: [[spoiler:Asha is the one who finally puts an end to Biomeka]]. This game used to be the SeriesFinale until the announcement of a [[VideoGame/MonsterBoyAndTheCursedKingdom new game]] in 2015. It is also the final game of the series to be released under Sega's helm, and thus the last one to sport the familiar ''Monster World'' title.
* ShooOutTheClowns: Pepe does not follow Asha during the final two levels [[spoiler:after nearly getting killed]].
* ShockAndAwe: The Sky Wizard's attacks consist of lighting bolts and turning his cloud hands into electricity. A few other enemies have electric attacks too, such as electric slimes.
* SpellMyNameWithAnS: This [[http://www.mpsnet.co.jp/hobbynet/Photos/YUJIN-050203L.jpg Sega Gals figurine]] of Asha and Pepelogoo, which predated the English version, spells their names as "Arsha" and "Peperogu" respectively (despite the latter used in the SoundTest).
* TakenForGranite: One of [[spoiler:Biomeka]]'s attacks.
* UndergroundMonkey: [[TheGoomba The slimes]] come in a few different varieties to match whatever world they're in, including fire slimes, electric slimes, and ice slimes. The green cyclopses also have red PaletteSwap counterparts who take more hits to defeat.
* UnderwaterRuins: Stream Sanctuary.
* VendorTrash: Gold bars. They can be sold to a woman in the Kingdom of Rapadagna for extra cash.
* TheVeryDefinitelyFinalDungeon: [[spoiler:The Underground Fort.]]
* YouGottaHaveBlueHair: Asha's green-colored hair.
