'''''Wonder Boy''''' is a side-scrolling platform game by {{Sega}} and Escape (now known as Westone Bit Entertainment) originally released for the arcades in 1986. The player controls Tom-Tom, a young boy in a tropical island who sets rescue his girlfriend Tanya from an evil witch doctor named Drancon. 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 SG-1000, MasterSystem and the GameGear, as well as a few 8-bit home computers (namely the ZX Spectrum, Amstrad CPC and Commodore 64). The game also received a licensed remake for the NintendoEntertainmentSystem by Hudson Soft titled ''VideoGame/AdventureIsland'', 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/File:WonderBoy_SMS_JP_cover.jpg Japanese cover art]] of the Mark III version, and it looks way more cheerful that its [[http://segaretro.org/File:WonderBoy_SMS_US_cover.jpg incredibly bland Master System counterpart]]. Now, check out the [[http://segaretro.org/File:Wonder_Boy_GG_US_front.jpg American Game Gear cover]]... hoo boy.
* ChestMonster: The spotted eggs contain a GrimReaper-type monster that drains your vitality.
* CountrySwitch: The Master System port changes its title to ''Super Wonder Boy'' when played on a Japanese console.
* DroughtLevelOfDoom: The desert levels, where obviously, food is scarce. As well as many of the later levels.
* DubNameChange: The names of the characters were gradually changed with each localized version. First of all, Tom-Tom was originally named Boy in the Japanese versions, while his girlfriend Tina became Tanya in the Master System version (presumably to distinguish her from [[VideoGame/AdventureIsland that "other" Tina]]). Finally, the main villain King was the last character renamed, as he was called Drancon in the 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.
* 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.
** For some reason, the Game Gear version was titled ''Revenge of Drancon'' in America (it was still called ''Wonder Boy'' everywhere else).
* TrueFinalBoss: Area 8 and the Evil 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.
