[[caption-width-right:209:Wonder Boy and Tina.]]
'''''Wonder Boy''''' is a side-scrolling platform game by Creator/{{Sega}} and Escape (now known as Westone Bit Entertainment) originally released for the arcades in 1986. The player controls the [[CharacterTitle eponymous Wonder Boy]], a young boy in a tropical setting who sets out to [[DistressedDamsel rescue his girl friend Tina]] from an [[MeaningfulRename Evil Witch Doctor]] known as [[AristocratsAreEvil King]]. Along the way he picks numerous power-ups such as skateboards and throwing axes while trying to maintain his vitality by eating as much food as possible.

''Wonder Boy'' was ported to various Sega platforms such as the [[UsefulNotes/OtherSegaSystems SG-1000]], UsefulNotes/SegaMasterSystem and the UsefulNotes/GameGear, as well as a few 8-bit home computers (namely the UsefulNotes/{{Commodore 64}}, UsefulNotes/AmstradCPC and UsefulNotes/ZXSpectrum). The game also received a licensed [[UsefulNotes/SoftwarePorting re-release]] for the NintendoEntertainmentSystem by Hudson Soft titled ''VideoGame/AdventureIsland'', [[DivorcedInstallment splitting the franchise into two directions]]. While the "Adventure Island" sequels remained true to the style of the original game for the most parts, the ''Franchise/WonderBoy'' sequels would take on a fantasy-themed action RPG approach.

!!Tropes in the original ''Wonder Boy:''
* AmericanKirbyIsHardcore: Here is the [[http://segaretro.org/images/e/e2/WonderBoy_SMS_JP_cover.jpg Japanese cover art]] of the Mark III version, and it looks way more cheerful that its [[http://segaretro.org/images/7/73/WonderBoy_SMS_US_cover.jpg incredibly bland Master System counterpart]]. Now, check out the [[http://segaretro.org/images/7/71/Wonder_Boy_GG_US_front.jpg western Game Gear cover]]... hoo boy.
* ChestMonster: The spotted eggs contain a GrimReaper-type monster that drains your vitality.
* ChuckCunninghamSyndrome: Despite Wonder Boy himself returning in two of the game's sequels (according to their respective manuals), his girlfriend Tina (along with the evil King) is nowhere to be found outside of a small mention in the home manual of the direct sequel, although this may have something to do with the ''Adventure Island'' confusion.
* CountrySwitch: The Master System port changes its title to ''Super Wonder Boy'' when played on a Japanese console.
* DroughtLevelOfDoom: The extra desert levels of the Master System, where food is obviously scarce. As well as many of the later levels.
* DubNameChange: The names of the characters were gradually changed with each localized home port [[http://segaretro.org/images/c/c6/Wonder_Boy_Arcade_JP_Flyer.jpg compared to the Arcade original]]. For example, in the English Master System version, Wonder Boy (or simply "Boy") was renamed "Tom-Tom" while his girl Tina became "Tanya" (presumably to distinguish her from [[VideoGame/AdventureIsland that "other" Tina]]); the main villain King was the last character renamed, as he was called "King Drancon" in the North American localization of the Game Gear version.
* EarlyInstallmentWeirdness: This game is the only game in the series to feature a prehistoric theme, not to mention the only game where the protagonist does not handle a sword... unless one counts the ''Adventure Island'' series as the true successor to this game, in which case the basic changes include the main character given a new identity, the redesigned damsel in distress, and the main antagonist replaced by other villains.
* HardModeFiller: All of the boss stages have the exact same template with different enemy and item placement, and most of the other level templates are reused at least once.
* HeadSwap: The boss in each world is literally the same boss with a different head. After being defeated he changes to his next head.
* MarketBasedTitle
** The Mark III version was titled ''Super Wonder Boy'', presumably to distinguish it from the earlier SG-1000 version released exclusively in Japan, since the Mark III was backwards-compatible with all SG-1000 games (also doubles as an UpdatedRerelease, as two extra areas were added and the dolls were given purpose besides points).
** For some reason, the Game Gear version (based on the above release) was titled ''Revenge of Drancon'' in North America (it was simply called ''Wonder Boy'' everywhere else).
* ReformulatedGame: The SG-1000 version is essentially a different game, with its own (smaller) set of original stages and music. The same goes for the home computer version (released for Commodore 64, Amstrad CPC and ZX Spectrum).
* TrueFinalBoss: In the Master System version, the last area and King's true form can only be reached by [[GottaCatchThemAll collecting all of the dolls]] [[GuideDangIt hidden throughout the game.]]
* WizardNeedsFoodBadly: Wonder Boy has to stay well fed, or else he'll die. In his two other appearances as Bocke Lee Temjin/Book the Hero in ''[[VideoGame/WonderBoyInMonsterLand Wonder Boy: Monster Land]]'' and again as Wonder Boy in ''[[VideoGame/WonderBoyIIITheDragonsTrap Wonder Boy III: The Dragon's Trap]]'', this has been done away with.
