History Main / GuardianEntity

* In ''Franchise/HarryPotter'', the [[GoodHurtsEvil Patronus Charm]] produces an AnimalBattleAura [[MadeOfGood made from positive emotion]] to act as a bulwark against BlackMagic monsters against which there is no other defense, namely the MadeOfEvil [[EmotionEater Dementors]] and their equally spooky cousins the Lethifolds. Its LatinIsMagic incantation, ''Expecto Patronum'', directly translates to "I expect a guardian".

** ComicBook/RachelSummers, Jean's alternate reality daughter, is in some ways even closer to this trope - while she doesn't die, the Phoenix is a bit more active about protecting her. The Phoenix protected her and helped convey her to the past in the first place, erasing the memories to protect her sanity, merged with her for a very long time, being genuinely protective of her, and then a fragment - a 'shadow' - merged with her when Korvus Rook'shir (then a PunchClockVillain) tried to use the Phoenix Blade that contained it to kill her. In the famous of his utter bafflement, she smirked, with a glowing blue Phoenix symbol over one eye, "The Phoenix knows me. It ''likes'' me."

** Harry's protection comes from [[spoiler: the Phoenix]], which goes to some lengths to obscure its identity in the first book, until finally revealing the truth in chapter 71 when Harry [[spoiler: gets killed]] and it goes berserk. Since the entity in question is now [[spoiler: merged with Lily]], this is [[MamaBear not especially surprising.]] In the sequel Harry learns to tap into that power in his own right, which is generally (and correctly) considered to be a terrible idea.

** The kas in the Memory World arc are the same, and the slabs they can be bound in make it clear that the slabs/original cards are essentially portable Guardian Entities. Otherwise, they act almost exactly like [=JoJo=] Stands, right down to being InvisibleToNormals.

* ''Wiki/SCPFoundation'':

* This is how [[LightNovel/AccelWorld Black Lotus]] is translated in ''VideoGame/DengekiBunkoFightingClimax'', being the Guardian Entity for Kuroyukihime.

In terms of strength, it might only be able to [[ForWantOfANail nudge]] [[SchrodingersButterfly butterflies]], or fully embody the HyperCompetentSidekick and bring down the Wrath Of {{God}}[=/=]{{Satan}}[=/=]CrystalDragonJesus on those who look funny at their ward. Speaking of that, the Guardian Entity is often its own master rather than completely subservient to its ward; in such a case, while it may take some input from said ward, it chooses who to hurt and how to do it all on its own. This can be especially nightmarish for the ward if they are [[PoisonousFriend psychotically overprotective]], and oversensitive or [[BlueAndOrangeMorality inscrutable]] as to what they consider "threats" to their ward.

* Some Native American nations have a RiteOfPassage called "guardian spirit quest" (Wiki/TheOtherWiki calls it "vision quest"). In this ritual, a boy fasts and meditates for several days to receive a visitation by an animal spirit who henceforth becomes his guardian and imbues him with some of its (magical) properties.

-->'''Devil Hulk:''' ....He needed a dad...Or something like a dad. Like a dad that loved him. But he didn't know what love was. Couldn't see love without pain. I can only come out at night. I only come out when I'm needed. When someone hurts him. Then...[[BerserkButton I]] [[ItsPersonal take]] [[RelativeButton it]] [[RoaringRampageOfRevenge personal.]]\\

* Wiki/{{SCP|Foundation}}-[[http://scp-wiki.wikidot.com/scp-204 204]], a "semi-organic [[{{Nanomachines}} nano-machine]] colony" which follows a kid around, and eats anyone who endangers the kid. (Or anyone the kid tells them to eat.)
** It is interesting to note that, in true SCP fashion, 204 appears to be malevolent, and kids "protected" by it ''always'' become cruel, reckless and more than willing to sic it on anybody who as much as looks at them funny. This profits SCP-204, since it subsists off devouring organic matter (i.e. the corpses of its victims). The Foundation theorizes that SCP-204 needs sustenance, but is not allowed to attack without its ward's permission, therefore it [[TheCorruption somehow changes its ward's thought patterns in order to have more opportunities to feed.]] To keep 204 from causing too much trouble, the Foundation provides it with orphans who are already broken by years of abuse. Worse, if no such children are readily available from orphanages, they take otherwise normal kids and put them under the "care" of ''D-class personnel convicted of violent crimes, child abuse, and pedophilia''.

* Charyeok in ''Anime/TheGodOfHighSchool'' is a [[SupernaturalMartialArts supernatural martial art]] that allows its users to borrow power from mythological entities and occasionally have them assist in fights as avatars.

** A sacred watchers is the spirit of a bodyguard who died while protecting their charge, but refuses to move on to the afterlife until their charge is safe. They spend most of their time watching over their charge from the Ethereal Plane, but can manifest on the Material Plane like a ghost and kick some ass when necessary. Though dead, sacred watchers are defined as "deathless" creatures rather than "undead," since they're virtuous souls powered by positive energy rather than parodies of life animated by negative energy; as such, ReviveKillsZombie and TurnUndead don't work on them.

** The Pharaoh himself always steps in to protect his host Yugi Mutoh whenever his well-being or that of someone he holds dear is in danger, especially in Season Zero when he was '''very''' vicious and borderline amoral.

* A twist on this in ''ComicBook/{{The Immortal Hulk}}'' as normally the Hulks in Bruce Banner are split-personalities that take over when he transforms and all of them seem to hate "Puny Banner". Except the [[NamesToRunAwayFromReallyFast Devil Hulk]]. Devil Hulk isn't exactly a version of Bruce but more like an ImaginaryFriend created when he was a child being abused by his father, Brian Banner. Devil Hulk was modeled after the serpent in Paradise Lost as Bruce was looking at the book when his father attacked him. Bruce wanted a loving father figure to look after him but couldn't imagine a father who wasn't scary or see love without pain so the Devil Hulk is simultaneously very protective of Bruce and takes the role of a paternal figure but is also incredibly violent and brutal. As Bruce modeled this Hulk after Satan, Devil Hulk is supernatural and can control the mystical form of gamma energy while performing feats that are scientifically impossible. Now that the Devil is out of Bruce, woe be to any who would seek to harm him.

* ComicStrip/RoseIsRose: Pasquale has a guardian angel who usually looks like a robed and winged twin of Pasquale... except when he senses a threat to Pasquale and transforms into an intimidating warrior angel with a [[{{BFS}} gigantic sword]].

* In ''LightNovel/TheTwelveKingdoms'', one of the later arcs concerns a Kirin who wound up getting stuck in the human world with amnesia - he was bullied for being 'weird', but fortunately, he has guardians: the Youkai he took as his servants back in the Twelve Kingdoms, acting from the shadows to keep him safe. Unfortunately, they don't have a lot of restraint, and resultingly, anyone who shows him the least bit of hostility or unkindness winds up having 'accidents', including a few deaths...

** Personas in the ''Franchise/{{Persona}}'' sub-series. Personas are an aspect of their wielder's psyche that take the name and ([[OurMonstersAreWeird heavily stylized]]) appearance of a character from myth or history that he or she can identify with, and can manifest to fight off supernatural threats. Regardless of the game, you must have a Persona to be able to defend yourself from [[DemonicInvaders shadows/demons]].

* The Stands from ''Manga/JoJosBizarreAdventure'' are the TropeCodifier for most Japanese media. Stands are a manifestation of the user's soul and the user dies if his or her Stand is destroyed (and '''usually''' vice versa), but they are incredibly powerful. Jotaro's Star Platinum is the one that fits the description the best, since it automatically intercepts attacks coming his way without him needing to do anything, and has SuperReflexes fast enough to BulletCatch a gunshot fired at him from point blank range.

* In ''Literature/NotLongBeforeTheEnd'', the Warlock is the most powerful human magician on the planet, and his greatest protection other than his own mind is one of these. His parents, themselves powerful wizards, knew that his greatest weakness would be his name, as anybody who knows and can pronounce your name can exert magical power over you. To protect him, they summoned a powerful demon, bound it to a tattoo on his back so that nobody else could summon it and ask it questions, made it give him a name no human could pronounce, and forced it to protect him with its life. Too bad about the magic sword Glirendree....

* In Norse Mythology you have the ''Watchers'' or ''Wardens'', a spirit that follows your soul from birth to death.

** Yubel was surgically restructured into their current dragon/fiend form in order to guard Judai, the person with the power of Gentle Darkness, until he became an adult. They kind of overdid it with the protection angle, though.

** Yubel was created/recreated/transformed from human to dragon/fiend/her standard form that we first knew her in in order to guard Juudai, the person with the power of Gentle Darkness, until he became an adult. She kind of overdid it with the protection angle, though.
