* Derflinger in ''LightNovel/TheFamiliarOfZero'' has the ability to turn his user into a puppet when they are unconscious.

* Creator/JunjiIto's one-shot manga ''The Sword of the Reanimator'' did this. The titular sword brings dead people back to life if they are cut by it, and the protagonist uses this ability to bring back his dead grandfather. However, the sword then takes control of them, and kills its previous owner so that it can bond itself to the protagonist, and this causes all the people it had revived to die again.

* Crona in ''Manga/SoulEater'' has a sword named Ragnarok that is physically part of [[AmbiguousGender his/her (it's hard to tell)]] body (via his essence being blended with hir blood). S/he always follows its directions, and during fight scenes is seen to be being dragged around by it.

* The DC Comic Book character Jessica Cruz when is possessed by the Ring of Volthoom: "You have been chosen, Jessica Cruz... To annihilate the Earth" (Justice League Vol 2: 2011-2016, Issue #30).

* ''Manga/{{Kandachime}}: Jyatou are demonic swords that take over their wielders, and come in two varieties: Zatsushoku lose control if they're broken or their wielder is disarmed, while Kurogane Shiki permanently take control of their wielders until their host is slain.

* ''Franchise/TheElderScrolls'' series has the recurring LegendaryWeapon Umbra, a sword which crosses over with EvilWeapon and EmpathicWeapon. It was forged long ago to [[YourSoulIsMine steal the souls]] of its victims. However, the wielder of the blade becomes a victim as well. Over time, it takes over the mind of the wielder, until they begin to refer to themselves as "Umbra", and turns them into a vicious BloodKnight. Either they slay their opponents and steal more souls for the sword, or they are slain, and the sword finds a new and more powerful wielder. The [[Literature/TheElderScrolls licensed novels]] take this UpToEleven, where Umbra is responsible for some NightmareFuel levels of genocidal rampage. There is even some indication that it is capable of influencing ''[[OurGodsAreDifferent Daedric Princes]]''.

* Variant in ''Videogame/GuiltyGear''. Eddie, Zato-1's weaponized LivingShadow, possesses its master's dead body after he passed away before ''XX''. The character is now referred solely as "Eddie".

* While it doesn't have a will of its own, Denkoumaru from ''Manga/{{Doraemon}}'' is a katana that comes with an AI and radar to determine the moves needed to defeat the holder's opponent(s), and carry out those moves by taking control of the arms of the holder. [[https://c1.staticflickr.com/5/4252/34323413334_7dbb77c6ca_o.jpg See how]] Doraemon makes one of the [[BigDamnMovie Big Damn Manga]] BigBad fall into trouble literally single-handedly with this katana while making some {{Exposition}} ''without even facing towards said BigBad''.

** The manga (and subsuqent anime adaptions) show the Guyver units to have something of an auto-pilot mode that kicks in when the unit is first installed, regenerates its host from the core medal or if the host suffers catastrophic head injuries. Its a brutally efficient fight, at least compared to Sho early on but its lack of nuance in dealing with what it perceives as threats leads to tragic consequences.
* ''Manga/FlameOfRecca'': weapons created by the bloodthristy Kaimon are hard to control at best, and can tend to have minds of their own.

* A rather ambiguous (and positive) example in the climax of ''Anime/MagicalGirlLyricalNanohaStrikers'' provides a somewhat more physical example than most: during a fight late in the show, Subaru is momentarily given a HeroicBSOD in the middle of a battle. Her Intelligent Device, Mach Caliber, is a pair of rocket-propelled rollerblades linked to a PowerFist on Subaru's right arm, and proceeds to briefly fight for her by firing its various jets to maneuver the three limbs it can control.

* In ''TabletopGame/Warhammer40000'', the [[HordeOfAlienLocusts Tyranid]] weapon-beast known as the Exocrine carries a [[LivingWeapon symbiotic]] [[PlasmaCannon bio-plasmic cannon]] on its back that is far more intelligent than the beast itself. The result of this is that the cannon's mind will supress its hosts simple mind so that it can move itself into an optimal firing position.

* The intelligent MorphWeapon Blackshard in ''Webcomic/{{Digger}}'' sometimes takes control of Komiyan's body to use itself more effectively in battle. [[spoiler:It's the first sign that Blackshard is actually a LeakingCanOfEvil for a powerful {{Body Surf}}ing spirit who wants to possess a proper body.]]

* The DC Comic Book character Jessica Cruz when is possess ed by the Ring of Volthoom: "You have been chosen, Jessica Cruz... To annihilate the Earth" (Justice League Vol 2: 2011-2016, Issue #30).

* The [[ZombieApocalypse Black Lantern Rings]] in ''ComicBook/BlackestNight''. "The rings are wearing the dead."[[/folder]]

* Intelligent items in ''TabletopGame/DungeonsAndDragons'' and ''TabletopGame/{{Pathfinder}}'' have egos that can override their wielders' minds if the item disagrees with their actions. For example, Pathfinder's Briar Blade was created to defeat invaders from the [[LandOfFaerie First World]] and will fight its owner for control if the owner gets too friendly with Fae creatures.

* The Berserker Nobodies in ''VideoGame/KingdomHeartsII'' wield "[[EvilWeapon cursed hammers]]" that visibly drag them around. Sora can steal them -- or Saïx's Claymore, during the fight against him -- with a Reaction Command, and he will be sent careening across the battlefield, hanging desperately onto the weapon while it tears through everything in its path

* Carvin' Marvin and Tremble in ''ComicStrip/KnightsOfTheDinnerTable''. As of issue #207, Tremble has taken over Sara's character, with Brian as her minon, and the pair are planning to TakeOverTheWorld.

[[RussianReversal In Soviet Russia]], [[TitleDrop weapon wields you!]]

** Kring from the first Discworld novel, ''Discworld/TheColourOfMagic'', is a talking sword who is not so much "empathic" as "annoying", leading at one point to Rincewind being forced to save the others because otherwise Kring would kill him.
** ''Discworld/MenAtArms'' features "The Gonne", a firearm that takes control of the mind of its bearer to the point that it aims and fires itself even though the marksman tries to resist it.

* In a non-sword example, necromancers (and Abhorsen) in Creator/GarthNix 's ''Literature/OldKingdom'' series need to be careful when using the bells. They are implied to have minds of their own, with particular ones are prone to using a moment of inattention to sound or create their own pattern, often to the wielder's detriment.
