''Worlds of Power'' was a series of {{novelization}}s of UsefulNotes/NintendoEntertainmentSystem games published in the early 1990s by Scholastic Books. They were written by several authors using the pen name "F.X. Nine". The books averaged about 120 pages long, and featured strategies for the featured game as an added incentive, either in a trading card on the inside cover or at the end of each chapter. At the end of each book was a list of recommendations for other books the author "thought you might like".

The quality of the books varies, as does the faithfulness to the game's plot. ''Blaster Master'' and ''Bionic Commando'' are generally regarded as the best adaptations, with the former even becoming canon to the game series.

There were eight books in the series, each named after the game on which it was based:
* ''VideoGame/BlasterMaster''
* ''VideoGame/{{Metal Gear|1}}''
* ''VideoGame/NinjaGaiden''
* ''VideoGame/CastlevaniaIISimonsQuest''
* ''[[VideoGame/WizardsAndWarriors Warriors & Wizards]]''
* ''VideoGame/BionicCommando''
* ''Infiltrator''
* ''[[VideoGame/{{Shadowgate}} Before Shadowgate]]''

There was also a ''Junior Worlds of Power'' series, aimed at an even younger demographic. They were physically bigger, but only about 70 pages long. There were only two books in the series: ''VideoGame/MegaMan2'' and ''Bases Loaded II''.

!!This series contains examples of:

* AdaptationExpansion: Considering how simple the games' plots were, a lot had to be added. Many of the stories add a great deal of backstory, or even additional characters:
** ''VideoGame/BlasterMaster'' adds Eve, a HumanAlien from another planet, as the original owner of the SOPHIA III vehicle. These details would later become canon in ''Blasting Again'', and elements of the novel were used in ''Zero''.
** One of the stranger examples is the ''Castlevania II'' book, which adds elements such as the heroes needing to rescue a woman named Linda Entwhistle who is apparently Simon's girlfriend, Dracula as a lackey for Thanatos, Master of Death, and an encounter with a friendly troll named Freddie. Strange because the kid who accompanies Simon is [[AscendedFanboy a fan]] of the ''Castlevania'' games and he specifically enters the world of the games, not just a fantasy world based on a video game in the reader's world.
* AdaptationalBadass:
** While the ''Bionic Commando'' hero is awesome as-is, the book had him be a ninja, a top-ranked spy, and gave his bionic arm several enhancements such as a TruthSerum and the ability to generate intense heat.
** Kilt was TheUnfought in the video game and didn't have much presence aside from an appearance in a neutral zone, but in the book he's an active threat who communicates with other characters frequently and co-pilots the Albatross alongside Master-D.
* AdaptationalWimp: Dracula was ''dead'' in ''Castlevania II'' and still ends up more threatening than his ''Worlds of Power'' counterpart, who's thwarted repeatedly by bad puns and jokes.
* AndIMustScream: Similarly to many ''Literature/{{Goosebumps}}'' books, characters frequently want to scream but can't, usually out of fear:
-->If Tim Bradley could have screamed, he would have let out a long, loud one. Unfortunately, he was so paralyzed with fear that he could barely move, let alone make a sound.
* BadGuysDoTheDirtyWork: Master-D kills the Hand when Jack finds himself cornered; it's justified in that the Hand had previously tried to kill him and he was out for revenge.
* BadassBoast: In the ''Bionic Commando'' book Master-D gets one when he kills the Hand and confronts Jack Markson, and Kilt gets one posthumously when the self-destruct sequence activates.
* BigEater: Most of the protagonists love to eat, especially Jack Markson and Timothy Bradley.
* {{Bowdlerize}}: To placate the parents, rarely did the villains actually die. Enemy soldiers would be taken out with tranquilizer bullets, animals and boss enemies turned out to really be robots, and there's a separate world for monsters that they're sent back to when they're defeated by meddling heroes, to name a couple.
* CanonForeigner: Several examples, usually to give the heroes love interests or partners:
** ''Bionic Commando'' adds Heather Willis, a female spy and fellow agent who planned to marry Joe before he was captured, and Tiger, a TagalongKid who wants to go to America and draws a map of Stage 5 for Jack.
** ''Castlevania II'' adds Linda Entwhistle, a girlfriend for Simon, a monster named Thanatos who Dracula is subservient to, and a friendly monster named Freddie.
* CliffhangerCopout: Chapter 4 of the ''Bionic Commando'' book ends with Jack suffering a flashback and forgetting how to work the grappling hook on the bionic arm as he leaps down an elevator shaft. Chapter 5 begins with it activating and saving him from the fall.
* TheComicallySerious: Simon Belmont's seriousness and inability to get jokes is played for humor at times, leading Timothy to be surprised when he makes a joke of his own.
* CompositeCharacter: The enemy bionic soldiers from ''Bionic Commando'' are comprised into one opponent named "The Hand."
* CyberneticsEatYourSoul: In the ''Bionic Commando'' book, Jack has trouble accepting the bionic arm at first, feeling as if it's not part of his body at all.
* DarkerAndEdgier: ''Bionic Commando'' gets fairly brutal with deaths on both sides once it hits its home stretch, and Jack's arm is cut off by ninja stars in the opening scene.
* DidYouJustPunchOutCthulhu: Tim taunts and attacks Thanatos, Master of Death, and alongside Simon is able to send him back to his home dimension.
* GettingCrapPastTheRadar:
** While Master-D's [[StupidJetpackHitler identity]] isn't mentioned in the novel for [[NoSwastikas obvious reasons]], the book does mention him hiding out in Brazil, Columbia, and New York, which is where some actual Nazis went after the war.
** ''Castlevania II'' keeps in lust as one of the Seven Deadly Sins.
* HumanityEnsues: While running Mega Man through a duplicating machine to better his odds against Dr. Wily's more powerful batch of robots, Dr. Light accidentally turns him into a human instead.
* HumanoidAbomination: In ''Castlevania II'', Thanatos is described as a humanoid monster, but his innards have galaxies and stars within:
-->Tim had a glimpse beyond jagged fangs and rotting molars... a glimpse of stars and nebulae, of shadows between planets and worlds being born and worlds dying.
* IShouldWriteABookAboutThis: Once Tim hears the plot of ''Castlevania II'' from Simon he thinks it'd make a fantastic video game.
* ImprobableAge: Ryu Hayabusa of ''Ninja Gaiden'' has his age lowered from adulthood to 13, making his travel to America and his whole journey rather improbable.
* InNameOnly: ''[[VideoGame/{{Shadowgate}} Before Shadowgate]]'' has nothing to do with ''VideoGame/{{Shadowgate}}''. It's ostensibly a prequel.
* LamePunReaction: Timothy Bradley's jokes are so lame they actually drive off Dracula when he possesses Simon early on:
-->"Arrgh!" cried Dracula's voice. Simon's body jerked back as though physically struck. "A pun! I abhor puns! If there's anything I can't stand more, itís stupid, silly jokes!"
* LemonyNarrator: ''Castlevania II'''s narrator slips into this at times:
-->Gosh, he was really in kind of a jam, and it wasn't the grape kind either.
* LighterAndSofter: Yes, they've been bowdlerized from E and E10-equivalent games. Wildlife is non-fatally diverted away in ''Ninja Gaiden'', or turn out to be robots for no real reason.
* MoralityChain: ''Catlevania II'' has Dracula's curse cause Simon to have to resist the Seven Deadly Sins, leading Timothy to rein him in when he has a bout with gluttony or anger.
* NamedByTheAdaptation: Master-D in ''Bionic Commando'' is short for Master Destructo.
* RevisedEnding: In ''Ninja Gaiden'', Ryu's dad doesn't die in the book like he did in the game.
* SevenDeadlySins: In ''Castlevania II'' Simon has to avoid these, as indulging in vices would make him susceptible to possession. Greed and pride are swapped for deceit and blasphemy, but lust stays as-is.
* ShoutOut: ''Castlevania II'' has references to Music/{{Metallica}} and ''Literature/TheStrangeCaseOfDrJekyllAndMrHyde''.
* ShownTheirWork:
** The ''Bionic Commando'' book mentions the Nazz, the prototype name for the Badds in the instruction manual, and the booby-trapped elevator scene mentioned in-game over the enemy communication devices. Master-D is also named accurately, as is Hal, a soldier you talk to near the very end of the game.
** The ''Mega Man 2'' book's descriptions of stages generally follow the layout of the game, and the Guts-Dozer, dragon, and the Wily alien hologram also feature.
* SparedByTheAdaptation:
** Subverted, as Kilt survives to the end of the ''Bionic Commando'' book past what killed him in the game, with his in-game death being given to his traitorous lackey The Hand. Then he gets blown up when the Albatross explodes and dies anyway.
** Played straight in ''Ninja Gaiden'', as Jo Hayabusa miraculously survives and even climbs out of the collapsing ruins with a makeshift crutch and splint. He joins Ryu and Irene for a victory laugh at the end of the book.
* TagalongKid: Many of the books, though not all, have the main character actually be some middle school student who goes on an adventure with the hero.
* TookALevelInBadass: Timothy Bradley goes from generally being TheLoad to using Simon's whip correctly and taking down Death, and helping to destroy Dracula in the finale.
* TotallyRadical: Used in a number of these books.
* TrappedInTVLand: Happens in the ''Castlevania II'' book, in which the KidHero gets transported to the world of the video game itself, which is treated as specifically the world of a video game, unlike, say, the ''[[VideoGame/WizardsAndWarriors Warriors & Wizards]]'' book, which treats Kuros's homeland as a fantasy world or other time period.
* WeaksauceWeakness: In ''Castlevania II'' Dracula can't stand bad puns or jokes, which are enough to stop him from possessing Simon.
