[[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 who embarks on a journey to help out spirits calling for her. 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 [[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 {{Wii}} VirtualConsole, PlayStationNetwork and 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'':
* ActionGirl: The new protagonist, Asha.
* AncientArabia: 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.
* BackFromTheDead: Three examples: 1) [[spoiler:Pepe]] returns to help you during the final battle. 2) The final boss, Fear Incarnate, is [[spoiler:Bio Meka]] from ''Wonder Boy in Monster World''. 3) [[spoiler:Pepe]] is revived again during the ending credits by Asha.
* BadassAdorable: Asha/Arsha 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.]]
* BigDamnHeroes: [[spoiler:A fully grown Pepe gets to be the hero twice]].
* ButtMonkey: Let's face it... Pepe. During the adventure, Asha gets him to do all sorts of harmful things (like serving as a platform while in contact with lava or getting frozen).
* 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 villian from Wonderboy 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''.
* 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''.
* 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 Pepeloogos turn to be malevolent little critters whom Fear Incarnate and the Warlocks are using to emotionally control the inhabitants of the town.]]
* DarkestHour: [[spoiler: After the yellow Pepeloogos reveal themselves, 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 what, the previously nice queen is going mad with power, and after confronting her, Pepe nearly dies and can't follow you anymore]].
* EvilAllAlong: [[spoiler: The yellow Pepeloogos through DemonicPossession that took place well before Asha came to town]].
* FantasyCounterpartCulture: Of AncientArabia in particular.
* FlyingCarpet: Used to reach the sky dungeon.
* HailfirePeaks: The Ice Pyramid is a mix of TempleOfDoom and SlippySlideyIceWorld.
* HeroicSacrifice: Done twice by the [[spoiler:the Pepelogoo]]. First, he [[TakingTheBullet takes the missile]] that the 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.
* HopelessBossFight: Just after completing the Sky Castle/Aegis Island, Asha must encounter the 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.]]
* InconvenientlyPlacedConveyorBelt: In the sky dungeon. They're tiny, and they move.
* ALoadOfBull: The ghost-like minotaur creature who appears in the pyramid stage.
* ObviouslyEvil: The Warlocks in their human forms. Scowling faces with black beards, pointy ears... Come on!
* RecurringRiff: Nearly the entire soundtrack consists of rearrangements of the game's main theme.
* RidiculouslyCuteCritter: The Pepelogoo.
* 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 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 Warlock of Heavens' attacks consist of lighting bolts and turning his cloud hands in electricity.
* SpellMyNameWithAnS: This [[http://www.mpsnet.co.jp/hobbynet/Photos/YUJIN-050203L.jpg Sega Gals figurine]] of Asha and Pepelogoo, which predated the official English release of the game, spells their names as "Arsha" and "Peperogu" respectively.
* TakenForGranite: One of Fear Incarnate's attacks.
* WingedHumanoid: The bird-woman who appears as a sub-boss in the vulcan stage.
* YouGottaHaveBlueHair: Asha's green-colored hair.
