* ''LightNovel/HybridxHeartMagiasAcademyAtaraxia'': Hida Kizuan can copy the Immoral weapons of the girls he does Heart hybrid with.

[[folder: Fan Works]]

* In ''LightNovel/TheHiddenDungeonOnlyICouldEnter'', Noir gets LifeEnergy from erotic acts with the opposite sex; however, this loses effectiveness quickly if he only plays around with the same girl over and over again, so he needs a harem to "spice things up" and keep that LP flowing, or he'd die.

* ''LightNovel/InAnotherWorldWithMySmartphone'': Touya [[MasterOfAll can use any spell ever created]], meaning he can use spells specific to any mages in his BattleHarem, and even [[OutsideContextMagic combine them]] to create RequiredSecondaryPowers for more complex abilities, such as SuperMode or {{Flight}}. [[spoiler:He also gains access to the island of Babylon, which is a base created by Professor Regina Babylon to aid him in his upcoming battle with the Fraze with access to an alchemy lab, a mass-production workshop, and facilities for producing HumongousMecha. Due to [[LovableSexManiac Regina's nature]], each piece also comes with a SexBot for Touya...including [[BrainUploading Regina herself.]]]]

* In ''Manga/MahouSenseiNegima'', Negi spends much of the series slowly amassing "Pactios" with [[BattleHarem the students of his class]] - a magical contract in which a [[SquishyWizard "Magister"]] empowers a [[MagicallyIneptFighter "Minister"]] to act as their [[SwordAndSorcerer partner in battle]], and creates a [[CardsOfPower Pactio Card]] with which the Minister can summon a powerful artifact matching their personality. Just before his climactic battle with [[WorldsStrongestMan Jack Rakan]], Negi enters a temporary Pactio as [[RoyaltySuperpower Princess Theodora]]'s Minister, receiving the artifact ''One Thousand Bonds'' - a cardholder which can summon the artifacts of any of his own Ministers, and [[LampshadeHanging is referred to even in-universe]] as a StoryBreakerPower.

* ''LightNovel/ISavedTooManyGirlsAndCausedTheApocalypse'' is a combination of this and StoryBreakerTeamup - due to being dragged into multiple stories from different genres, Rekka gets to [[WrongContextMagic use abilities and equipment in places where no one sees them coming]]. Can't pull out the SwordInTheStone? Just borrow the alien girl's teleportation device!

* ''LightNovel/RokujyoumaNoShinryakusha'': This is a very downplayed trope, played in a more practical, long-term method than usual. Koutarou finds himself in situations where one of the girls in his harem teaches him some type of skill or bestows upon him an item or skill that slowly starts to turn him from an OrdinaryHighSchoolStudent into the spitting image of the legendary Blue Knight. [[spoiler:This allows Koutarou to eventually become the Blue Knight (via TimeTravel)]]. A full list: Sanae alters his body so he can see and manipulate spiritual energy, Theia gives him PoweredArmor and the high-tech sword Saguratin, Ruth trains him in sword-fighting, Yurika gives him a defensive enchantment, Kiriha gives him a gauntlet that produces fire and electric attacks, [[spoiler:Clan maintains his armor and incorporates the gauntlet into it, Alaia gives him the magic sword Signaltin, either Alaia or Harumi are needed to fully use the power of Signaltin, and Maki creates a mental link with him]]. However, Koutarou doesn't feel like he deserves the respect given to him due to his power coming from others.

* ''Manga/TrinitySeven'': Amongst Arata's plethora of powers and abilities, he possesses PowerCopying, so long as he follows certain prerequisites to using an ability. His BattleHarem thus often takes it upon themselves to teach him to use their abilities (such as FullContactMagic) to stand a chance against the latest ArcVillain. He is also in possession of multiple [[SpellBook Grimoires]] and even created an avatar for Lilith's Grimoire that has a mix of both "parent's" magic, which he can tap into at any time if his is depleted.
* ''Manga/TwelveBeast'': Eita already has implausible ninja training, but gets superpowers when any of the girls he travels with fuses with his metal gauntlet (the harpy gives agility, the minotauress gives strength, etc.). Unfortunately, this involves him putting his hand on their breast.
* ''Anime/{{Vandread}}'': Hibiki gains access to a Mecha that can combine with the mecha of several of the female heroines. [[DoesThisRemindYouOfAnything The girls fight over who gets to combine with him]] and each fusion grants a different and specific power to the resulting "offspring". In the final battle, [[spoiler:the mecha of the hero and all of the women combine into the "Super Vandread", which has all of the powers of the various fusions.]]
* ''Manga/YoukaiShoujoMonsuga'': The various {{Youkai}} girls can project their spirit into Yatsuki [[EquippableAlly to grant him weapons or armor]] themed after their abilities. Initially he's [[MultiformBalance limited to one at a time]], but [[NextTierPowerUp after figuring out how]] to [[FusionDance fuse his soul with theirs]] he's able to [[AllYourPowersCombined equip all of their powers at once]].

* ''[[VideoGame/Conception2ChildrenOfTheSevenStars Conception]]'': The main character Itsuki is a "Visitor"--a SummonEverymanHero tasked to fight the "impurities" which threaten it. To do this, he must romance twelve [[spoiler:(later thirteen)]] maidens of virtue who will bear his "Star Children". Actually, mating isn't a requirement of the experience, but it does involve a lot of GRatedSex. He must "conceive" as many Star Children from each of the women in order to have an army strong enough to clear the impurities.

* ''LightNovel/MagikaNoKenshiToShoukanMaou'': Kuzuki Hayashizaki is granted by his contracted summon Lemegeton the ability to use the magical powers of the girls in his harem. The more he and a girl love each other (Lemegeton clarifies it has to be love, ''not'' just friendship), the more powerful spells he can access.

[[spoiler:He also gains access to the island of Babylon, which is a base created by Professor Regina Babylon to aid him in his upcoming battle with the Fraze with access to an alchemy lab, a mass-production workshop, and facilities for producing HumongousMecha.

Sister trope to BattleHarem, and the two can overlap. It can also overlap with the aforementioned CombiningMecha such as in the series ''Anime/{{Vandread}}'', described below.

In videogames, this is related to LevelUpAtIntimacyFive.

* ''LightNovel/RokujyoumaNoShinryakusha'': This is a very downplayed trope, played in a more practical, long-term method than usual. Satomi finds himself in situations where one of the girls in his harem teaches him some type of skill (such as swordfighting) or bestows upon him an item or skill (like a sword or armor) that slowly starts to turn him from an OrdinaryHighSchoolStudent into the spitting image of the legendary Blue Knight. [[spoiler:This alludes to the fact that Satomi is, in fact, the Blue Knight (via TimeTravel) and most of the girls have some sort of connection with him.]]

A character becomes Harem-Powered when some or all members of their harem of {{Love Interest}}s ([[HaremSeeker wanted]] or [[UnwantedHarem otherwise]]) [[AllYourPowersCombined grant them powers, equipment, abilities or immunities]]. This can be in general (granting LifeEnergy to the central character) or very specific ([[WithOurSwordsScene granting one unique item/ability]]). In narrative terms, this trope typically acts as an unspoken justification for why [[MarryThemAll the character can't choose only partner]], as rebuking any member of the harem would affect their optimal combat ability. In some cases, the character may only be able to [[MultiformBalance access one power at a time]], but still needs to keep members of the harem around in case they need that specific power at a specific time.
