History Main / ImmortalGenius

* ''Fanfic/ChildOfTheStorm'' has Doctor Strange, who is indeterminately ancient, having been Sorcerer Supreme since 1645 and to have done a ''lot'' of time travelling. Thanks to the latter, no one's entirely sure how old he is even if they make a shrewd guess of when he was actually born (until he finally reveals that [[spoiler: even he doesn't know, as he stopped counting once he passed ''100'' '''''thousand''''' years old, and his best guess is that he's around 500,000 now]]). He is also by far the smartest character in the entire cast, with only Thanos being noted as his equal. Between them, they're behind more or less everything. He's also an OmnidisciplinaryScientist and RenaissanceMan - he's mastered magic to the point where he can casually do things that pretty much everyone else believes to be impossible, he's the greatest doctor who ever lived because as he likes to remind people, he ''is'' [[NotThatKindOfDoctor that kind of doctor]] (and it's all he ever ''wanted'' to be), and he's the greatest bard ever to live as a ''hobby''. As WordOfGod has pointed out, given how much practice he's had, it would be kind of sad if he ''wasn't'' this.

* ''LightNovel/{{Baccano}}'': Szilard Quates was already a skilled alchemist before becoming immortal, and he's spent the last two hundred years conducting research to expand his knowledge, wanting to someday learn everything. He has enough alchemical knowledge to create his own homunculus servant and recreate the immortality elixir when he had only half the original recipe. Immortals have the ability to absorb other immortals to steal their memories and knowledge, so in addition to his own research, Szilard has been hunting down other immortals to absorb them and add their knowledge to his own. [[spoiler: When Firo becomes immortal and absorbs Szilard, he gains all of Szilard's knowledge but refuses to use it out of fear that it might tempt him into becoming as cruel and power-hungry as Szilard.]]

* ''Film/Infinite:''

* ''VideoGame/FinalFantasyXIV Endwalker'' introduces the people of Ea, a ProudScholarRace who wanted to learn all the secrets of the universe. To that end, they discovered the means to [[{{Transhuman}} shed their physical bodies and become living aether]], immortal beings to continue to learn forever. This proved to be their undoing [[spoiler:as they eventually discovered that [[NaturalEndOfTime the universe would inevitably end in Heat Death.]] As immortals, they were going to see the universe freeze to death and be powerless to stop it. Their civilization crossed the DespairEventHorizon and was destroyed by the Final Days.]]

** [[TheMan The Technocracy]] has their own equivalent of these, known as Archmasters, kept alive through [[MagicByAnyOtherName Enlightened Science]] for centuries and still capable of incredible feats. In one case, Johannes Kepler is not only still alive and kicking, but he even helped Einstein develop faster-than-light travel in the 20th century!

* ''Franchise/XMen'':
** Nathaniel Essex AKA Mr. Sinister has been alive since the Victorian Era, having been made immortal thanks to the intervention of Apocalypse, and even now is still widely known as a MadScientist ''par excellence'' specializing in biology and genetics.
** Sinister's boss, Apocalypse, is no slouch in this department either: not only is he an immortal mutant that's been around for over five thousand years, his experience with alien technology has made him a brilliant OmnidisciplinaryScientist and inventor capable of outstripping modern technology -- hence why his Horsemen of the Apocalypse usually go into battle with new weapons and a significant power boost.
** ''ComicBook/JonathanHickmansXMen'' reveals that [[spoiler: Moira [=McTaggert=] ]] is actually a mutant blessed with BornAgainImmortality by way of GroundhogDayLoop. Not only is the character a brilliant geneticist that even created a working cure for mutation in their third lifetime, but after opting to side with mutants instead, has been using the knowledge acquired over multiple lifetimes to benefit various influential figures -- including Professor X, Magneto, and even Apocalypse. [[spoiler: Having [[OutOfContinues run short of lifetimes]], she's decided to once again throw in her lot with Professor X, revealing ''all'' her secrets to him.]]

* ''Film/TheManFromEarth'': Subverted. John Oldman has lived for over twelve thousand years and spent a good deal of that time learning as much about the world as he could, even earning ten doctorates. However, he realistically can't keep up with the latest developments on every single possible field, especially since he has to move on every few years so that nobody notices that [[TheAgeless he doesn't age]], so most of his degrees are out of date by now. Plus, his mind isn't any different from that of an ordinary human, so [[TheFogOfAges he can't remember literally everything he's experienced]], only the highs and lows -- to the point that he's had to fill in the blanks with modern archaeological knowledge.

* Aja Oba of ''ComicBook/InfinitumAnAfrofuturistTale'' has been alive since before the birth of the Roman Empire and goes on to live for ''[[TimeAbyss billions]]'' of years, apparently possessing CompleteImmortality. He's also [[GeniusBruiser fiercely intelligent]], aided by the fact that he has more time to study than any other human being in the world: after settling down in the 21st century, he begins studying physics and technology to pass the time, eventually mastering enough to start his own company, bankroll space colonization, and lead his own team of scientists in terraforming a new world. [[spoiler: After transcending humanity in the wake of an alien invasion, he even rules over Earth as a combination GodEmperor / PhilosopherKing.]]

* [[Characters/DCComicsVandalSavage Vandal Savage]] is a Cro-Magnon warrior who became immortal after encountering a strange meteorite. For centuries, he undergoes a lot of aliases as attempts to dominate the world while accumulating a lot of knowledge in different fields in arts, combat, history, and science. This makes him one of the most dangerous villains in the DC Universe. He's also associated with the Secret Society of Super-Villains and the Injustice Society and is the founder of [[TheIlluminati The Light]] in ''WesternAnimation/YoungJustice''
* Dr Manhattan of ''ComicBook/{{Watchmen}}'' is blessed with CompleteImmortality, being not only effectively unaging but invincible. He's also a brilliant scientist and, thanks to his ability to perceive and interact with sub-atomic particles, is directly responsible for the technological uplift that the world has undergone. Indeed, it's implied that the only reason why he was able to reassemble his disintegrated body and become Dr Manhattan in the first place was because of his unique knowledge of both particle physics and [[TheWatchmaker watchmaking.]]

** Sinister's boss, Apocalypse, is no slouch in this department either: not only is he an immortal mutant that's been around for over five thousand years, his experience with alien technology has made him a brilliant OmnidisciplinaryScientist and inventor capable of outstripping modern technology - hence why his Horsemen of the Apocalypse usually go into battle with new weapons and a significant power boost.
** ''ComicBook/JonathanHickmansXMen'' reveals that [[spoiler: Moira [=McTaggert=] ]] is actually a mutant blessed with BornAgainImmortality by way of GroundhogDayLoop. Not only is the character a brilliant geneticist that even created a working cure for mutation in their third lifetime, but after opting to side with mutants instead, has been using the knowledge acquired over multiple lifetimes to benefit various influential figures - including Professor X, Magneto, and even Apocalypse. [[spoiler: Having [[OutOfContinues run short of lifetimes]], she's decided to once again throw in her lot with Professor X, revealing ''all'' her secrets to him.]]

** Changeling Emperor Blackthorn is widely considered to be one of ''the'' greatest schemers and manipulators in the current generation of gods, having together with his Summer Court move entire nations like pieces on a board and made pawns out of other pantheons. His talent in manipulation is such that even the [[TheOldGods Grand Primevals]] themselves are impressed by him, and even seek out his aid in various crises, such as 'Final Ragnarok'.

** Princess Twilight Sparkle (now Princess Amicitia Sparkle Equestria) is a mix of both this and EmperorScientist. A magical and scientific prodigy even as a mortal, she Ascended to demi-godhood by finishing a spell created by the Pillar of Equestrias' Starswirl the Bearded, who notably had trouble with completing it himself. Following her first Ascension, she would create and pioneer various spells and {{Magitek}} well into the Fourth Age. After Ascending to true godhood [[spoiler:and becoming [[TheOldGods Mana Equus]]' reincarnation]], she would continue her work, all while being [[ModestRoyalty humble royalty]]. Indeed, she would earn her reputation as being one of the most powerful and accomplished divine mages alive.
** Vicearch Iniquitous is widely considered one of the greatest Dark Magic practitioners to ever arose in the Ages of Known History. Her power and skill can be traced back to spending countless millennia devouring various supernatural beings - including whole pantheons, legions, and nations worth of gods - and assimilating their power into Herself, while devoting considerable time and effort in learning, studying, and experimenting with hundreds, if not thousands of divine domains she inherited as a consequence. Her magical ''magnum opus'' is a series of [[TomeOfEldritchLore infernal spellbooks]] titled the ''Seven Keys of Iniquitous'', each book containing both powerful spells and philosphical essays written by Her and others. Due to Her being extremely security-conscious, only those Iniquitous has deemed worthy can access the original books, like Karaldina de Hex and Blue Suede Heartstrings/King Caerulus Melodia Equestria-Corporatum.

* ''Fanfic/StoryShuffle1'': In [[https://www.fimfiction.net/story/216813/11/story-shuffle/in-the-details "In the Details"]], a group of demonologists consult the entity known as Laplace for information, believing him to be capable of providing them with the answers they need. Presumably he's immortal, or at least very long-lived, as he's outlived "generations of demonologists". [[spoiler: The information he provides is due to being effectively omniscient and capable of seeing the future... but by seeing the future, he reduces it from infinite possibility to utter certainty, hence why he's known as "The Puppet of Predestination."]]

[[folder:Film - Live Action]]
* The Ancient One of ''Film/DoctorStrange2016'' is TheAgeless, and while it isn't established how old she is, she's learned more about magic than any other character in the film. Essentially the epitome of the "wise eternal sage" version of this trope, she comes across as practically omniscient thanks to her study of the future - to the point that she's not even surprised when [[spoiler:a time-travelling Bruce Banner shows up on her doorstep]] in ''Film/AvengersEndgame''.
* In ''Film/GroundhogDay'', Phil Connors uses his time trapped in a GroundhogDayLoop to become an expert on whatever subject he needs to impress Rita on their repeated date to help things go well, including piano and the French language. Though due to the nature of the loop, from the perspective of everyone else, he's an InstantExpert.
* Subverted in ''Film/TheManFromEarth'': John Oldman has lived for over twelve thousand years and spent a good deal of that time learning as much about the world as he could, even earning ten doctorates. However, he realistically can't keep up with the latest developments on every single possible field, especially since he has to move on every few years so that nobody notices that [[TheAgeless he doesn't age]], so most of his degrees are out of date by now. Plus, his mind isn't any different from that of an ordinary human, so [[TheFogOfAges he can't remember literally everything he's experienced]], only the highs and lows - to the point that he's had to fill in the blanks with modern archaeological knowledge.

** Deconstructed in the case of [[TheAssimilator Father]]. A practically-immortal network of tendrils spanning an ocean, he was supposedly "old before the first sentient lit his first rocket," and has been absorbing the minds of everyone stranded on his moon - giving him an incredible database of knowledge with which to repeatedly defeat Toomin over the course of their decades-long games... but as Toomin discovers, Father can only recall what he's learned from his victims, [[CreativeSterility never improvising or developing any of it]]; in fact, without victims to sponge knowledge from, he's just an AlmightyIdiot. [[spoiler: Toomin eventually uses this to win at the game, absorbing all the minds that composed Father and taking his first step on his transformation into the Ellimist.]]

* In ''Literature/TheChroniclesOfAmber'', most of the immortal siblings who drive the plot just loiter around or vie against each other over Amber. Meanwhile, Benedict chose to devote his immortality to studying the theory and practice of war in all its aspects. The protagonist Corwin, who's otherwise an unscrupulous [[AntiHero anti-hero]] with obvious designs upon the throne, openly says that if Benedict ever deigned to vie for the throne himself, he'd just step aside and submit.

* ''Literature/TheExpanse'': Winston Duarte--already the mastermind of a preemptive attack that placed all human-colonized worlds under his control--attempts to use the protomolecule to make himself into an immortal god-emperor of humanity. [[spoiler: It doesn't work, at least for Duarte. Amos, on the other hand, ends the series still alive and well after a thousand years and at least three injuries that would have been fatal for anyone else.]]

* In ''Literature/PercyJacksonAndTheOlympians'', Daedalus is the greatest inventor who ever lived, and has escaped death by [[spoiler:{{Body Surf}}ing between robot bodies]] for thousands of years.
* Deconstructed in ''Literature/{{Repeat}}'': Brad Cohen finds himself stuck in a GroundhogDayLoop that begins in the womb and ends on the night before his fortieth birthday. Naturally, he often uses his knowledge of the future to become rich and famous, while also gaining mastery of various disciplines over the centuries - to the point that even scholars are impressed by his fluency in Hebrew. Unfortunately, being the Immortal Genius is very hard on Brad's sanity: TimeLoopFatigue destroys his ability to distinguish between his past lives, leaving him showing up to jobs he was never hired for, forgetting conversations he had a short time ago, randomly predicting the future to complete strangers, and demonstrating skills that he couldn't logically possess. By the end of this particular life, he's regarded by many as a MadOracle.
* In ''Literature/TheSecretsOfTheImmortalNicholasFlamel'', most of the immortal humans are experts in many different fields, including magic. In the case of the Flamels, they ''have'' to be the best alchemists in the world, since their alchemy is the only thing ''keeping'' them immortal. [[OurVampiresAreDifferent Scathach]] is a master of pretty much all forms of martial arts, and it's implied she may have invented some of them in the first place.
* In ''Literature/SeptimusHeap'', Marcellus Pye has had 500 years to learn everything there is to know about alchemy, though he was already the foremost expert on it before he became immortal.

* The Franchise/StargateVerse features several:
** Zig-zagged by the [[PuppeteerParasite Goa'uld]] of ''Series/StargateSG1'': they can naturally live for centuries and expand their lifespans into immortality through use of [[ImmortalityInducer sarcophagi]]... but they're not as omniscient or as clever they'd like their worshippers to think. Their technology was just reverse-engineered Ancient tech, and the Goa'uld [[AwesomeButImpractical designed it to impress rather than function]]. Worse still, their gigantic egos and [[SanitySlippage brain-addling use of]] [[ToxicPhlebotinum the sarcophagi]] prevent them from acknowledging this. However, a rare few Goa'uld have escaped this stereotype to become genuinely inventive, brilliant, and extremely dangerous - most notably [[BigBad Anubis]], who not only has [[TechnologicallyAdvancedFoe access to unique technical knowledge]], but is also [[TheDisembodied partially Ascended]] and has no need of a sarcophagus.
** By the start of the series, [[NeglectfulPrecursors the Ancients]] have [[AscendToAHigherPlaneOfExistence ascended to a higher plane of existence]] and are now immortal energy beings; on top of being near-omniscient sages with godlike powers at their command, they were responsible for creating some of the most advanced technology in the universe before they Ascended. Most are bound by an AlienNonInterferenceClause and are of very little help to anyone, but more pragmatic Ancients like [[BigGood Oma Desala]], [[OracularUrchin Orlin]], and Myth/{{Merlin}} will occasionally buck the rules by serving as mentors and allies to the main characters.
** The Ori are also Ascended immortals... and have used their omniscience and technical knowledge to empower their worshippers into a vast army of crusaders equipped with incredibly advanced warships and led by genetically-augmented SuperpoweredMooks. In other words, they're what happens when [[EvilCounterpartRace the Ancients go horribly wrong]].
** [[OurVampiresAreDifferent The Wraith]] of ''Series/StargateAtlantis'' are practically immortal so long as they continue to feed on other living beings. Of them, "[[NobleDemon Todd]]" has been alive for over ten thousand years and survived more tight scrapes than any other Wraith in the show. He's also [[GeniusBruiser the most intelligent and scientifically-minded of them]] - to the point that when [=McKay=] desperately needs to hack a rogue swarm of nanites, [[EnemyMine he's ultimately forced to consult Todd for answers]].

** Thoth of Myth/EgyptianMythology, who was credited with the creation of ''writing'' and the author of all works of science, religion, and magic.
** Athena of Myth/ClassicalMythology, who has a vast list of inventions attributed to her, including everything from chariots to musical instruments.
** Odin, though primarily the TopGod of Myth/NorseMythology, was also the god of knowledge, having sacrificed one of his eyes in exchange for wisdom. Not only do his ravens continuously supply him with information, but he's actually a poet. Unfortunately, he's also a trickster on par with Loki, making him a bit more morally ambiguous than most gods of knowledge.
* Merlin in ''Myth/ArthurianLegend'' is often portrayed as this, though while some have him be simply immortal, others give him the aptly named MerlinSickness, so that he ages backwards. In either case, he is generally the oldest and wisest character in any work he is in.

** One faction of immortals known as the Seekers of Knowledge specifically devotes themselves to gathering occult secrets over the centuries; as such, their immortality - achieved via BodySurf - is acquired specifically for the purposes of preserving rare information.

* Justified in ''TabletopGame/DungeonsAndDragons'': In all iterations of the game, [[OurLichesAreDifferent liches]] have extremely high intelligence, since becoming a lich in the first place requires being a powerful wizard, and wizards gain their magic through study and intellect.
* ''TabletopGame/MageTheAscension,''
** Several [[TheArchmage Archmages]] have achieved immortality and are often centuries old, if not older - to the point that many of them can no longer live on Earth without experiencing constant [[MagicMisfire Paradox]], instead secluding themselves in [[PocketDimension Horizon Realms]] deep in the [[SpiritWorld Umbra]]. Thanks to a mixture of experience and the understanding of magic they acquired just to get this far, Archmages such as these are often the greatest known experts in their field of study.

* In ''TabletopGame/VampireTheMasquerade'', some elders have spent centuries mastering their chosen fields of study and have achieved a level of mastery that mortals can only dream of, especially in the case of clans with a scientific or scholarly bent - such as the Tremere and the Tzimisce. In various ''Gehenna'' scenarios, both Lord Tremere and Saulot demonstrate such impressive knowledge of magic and strategy that the only thing that can trump their plans is another Antediluvian [[spoiler: most commonly [[EldritchAbomination Tzimisce]].]] Meanwhile, in "Fair Is Foul", the ancient CourtMage Mekhet has devoted so many millennia to studying magic that he has mastered ''all'' forms of blood magic.

** [[LooksLikeOrlok The Necrarch vampire bloodline]] is composed almost entirely of scholars, mages, and necromancers, and are obsessively dedicated to the pursuit of knowledge - especially that of dark magic. Indeed, they've become so skilled in the dark arts that they rarely need to feed on blood, instead sustaining themselves through the Winds of Magic alone, and regularly surround themselves with new and experimental forms of unlife.
** The Liche Priests of Nehekhara were charged with devising a means of guaranteeing the immortality of the kings they served, and to that end made themselves effectively immortal - or at least [[AgeWithoutYouth unable to die of old age]]. As such, their expertise is put to use in preserving the enchantments used to protect the tombs of their masters and resurrecting these ancient kings when the time comes. For good measure, the magic they practice is ''extremely'' complicated and can only be used by those old enough to have mastered their intricate arts.

** [[GodEmperor The Emperor of Mankind]] was - prior to his mortal injury and [[DarkLordOnLifeSupport internment on the Golden Throne]] - blessed with agelessness, near-invincibility, and near-godlike psychic powers... and before he actually claimed the title of Emperor, he served as an advisor to kings, a CourtMage, and a scientist. Over the course of unifying humanity under his own banner, he [[EmperorScientist continued to demonstrate his impressive scientific credentials]] by genetically engineering armies of {{Super Soldier}}s and creating the near-godlike Primarchs that would lead them. Unfortunately, the Emperor demonstrated a critical gap in his knowledge when it came to things like [[LackOfEmpathy psychology or compassion]], [[FatalFlaw a problem that was to be his undoing]]...

* ''VideoGame/FinalFantasyXIV Endwalker'' introduced the people of Ea, a ProudScholarRace who wanted to learn all the secrets of the universe. To that end, they discovered the means to [[{{Transhuman}} shed their physical bodies and become living aether]], immortal beings to continue to learn forever. This proved to be their undoing [[spoiler:as they eventually discovered that [[NaturalEndOfTime the universe would inevitably end in Heat Death.]] As immortals, they were going to see the universe freeze to death and be powerless to stop it. Their civilization crossed the DespairEventHorizon and was destroyed by the Final Days.]]

** [[HumanoidAbomination Lilith]] was alive during the First Age, and has parlayed her in-depth experience with long-lost technology into a career as a scientist in the eons that followed - on occasions when she wasn't making a name for herself as a monster or a goddess, of course. In fact, it's due to this incredible technological knowledge that she and her equally immortal husband [[FallenAngel Samael]] have built a respectable public life as [[spoiler: the heads of the [[MegaCorp Orochi Group]], recreating the LostTechnology of the Third Age to give their corporation its technological edge.]]

* Mercurius, a God from ''VisualNovel/DiesIrae'' and [[TimeAbyss ancient]] even by the standards of the [[VisualNovel/ShinzaBanshoSeries Shinza verse]], is considered the wisest and most knowledgeable out of all the Gods as well as the father of magic, mostly thanks to the fact that he has been around for so long and through so many timelines that he just simply knows all there is to know. The series does however makes a distinction between Wisdom and Genius, as the God that came before Mercurius, Nerose Satanel whose also an example of this trope, would fit the latter category as he is able to think up new things thanks to his intellect while Mercurius is more of a walking dictionary built from experience.

[[folder:Web Comics]]
* Sarda the Sage of ''Webcomic/EightBitTheater'' is not only the most powerful and intelligent mage in the setting but also effectively immortal, having [[TimeAbyss lived for billions of years]] [[spoiler: as a result of a failed plan to go back in time and kickstart the beginning of the universe.]] In the present, he's essentially SeenItAll - enough to serve as an extremely manipulative guide to the Light Warriors - and he's learned enough about magic to [[RealityWarper essentially warp reality]] as well.

* In ''WesternAnimation/Castlevania2017'', a bit point is made of the vast amount of knowledge Dracula has gathered over the years, including technology and science lost to humanity. Isaac cites this as the reason he follows Dracula (aside from his misanthropic tendencies), considering him the most important person in the world, and both Alucard and Sypha mourn the loss of Dracula's knowledge when they set out to kill him.

** [[AllPowerfulBystander The Ellimist]] is a CosmicEntity that never ages and likely can't be killed without destroying the entire universe as well. Not only is he virtually omniscient across time and space, but having been alive for millions of years, he's also a wellspring of information on subjects that most species have long forgotten. On top of playing an incredibly complicated game with Crayak for the fate of the universe, he also engineered an entire race to further his goals and created the legendary Time Matrix at some point in the distant past. [[spoiler: Indeed, it's revealed he first achieved immortality by drawing upon the knowledge he acquired from Father to create a unique starship that could preserve his aging body, upgrading himself over the centuries until he [[AscendToAHigherPlaneOfExistence transcended physical existence altogether]].]]

** Deconstructed in the case of [[TheAssimilator Father]]. A practically-immortal network of tendrils spanning an ocean, he was supposedly "old before the first sentient lit his first rocket," and has been absorbing the minds of everyone stranded on his moon, giving him an incredible database of knowledge with which to repeatedly defeat Toomin over the course of their decades-long games... but as Toomin discovers, Father can only recall what he's learned from his victims, [[CreativeSterility never improvising or developing any of it]]; in fact without victims to sponge knowledge from, he's just an AlmightyIdiot. [[spoiler: Toomin eventually uses this to win at the game, absorbing all the minds that composed Father and taking his first step on his transformation into the Ellimist.]]

* Deconstructed in ''Literature/{{Repeat}}'': Brad Cohen finds himself stuck in a GroundhogDayLoop that begins in the womb and ends on the night before his fortieth birthday. He uses his knowledge of the future to become rich and famous, while also gaining mastery of various disciplines over the centuries - to the point that even scholars are impressed by his fluency in Hebrew.

By the end of this particular life, he's regarded by many as a MadOracle.

* In ''Literature/TheChroniclesOfAmber'', most of the immortal siblings who drive the plot just loiter around or vie against each other over Amber. Meanwhile, Benedict chose to devote his immortality to studying the theory and practice of war in all its aspects. The protagonist Corwin, who's otherwise an unscrupulous [[AntiHero anti-hero]] with obvious designs upon the throne, openly says that if Benedict ever deigned to vie for the throne himself, he'd just step aside and submit.

** The Liche Priests of Nehekhara were charged with devising a means of guaranteeing the immortality of the kings they served, and to that end made themselves effectively immortal - or at least [[AgeWithoutYouth unable to die of old age]]. As such, their expertise is put to use in preserving the enchanted used to protect the tombs of their masters and resurrecting these ancient kings when the time comes. For good measure, the magic they practice is ''extremely'' complicated and can only be used by those old enough to have mastered their intricate arts.

** Golden Scepter, the Radiant Emperor is already a psychic prodigy and peerless genius even by Alicorn standards, and this has only increased with his ever-expanding knowledge and experience throughout his millions of years of existence. His empires are noted to be extremely advanced in terms of technology and magic/psionics compared to other civilizations ruled by his fellow Alicorns, with the Fourth Age's Terran Empire being the birthplace of many psionic and technological wonders. Even his golden PoweredArmor, implied to be another one of his creations, is such an advanced piece of work that [[MadScientist Crazy Ant]] went absolutely ''gaga'' upon seeing it in person.

* ''ComicBook/{{Planetary}}'': Elijah Snow is a Century Baby, a superhuman with extraordinary skills and powers including immortality... and he also happens to be a natural born genius, particularly in business and archaeology.

* ''Fanfic/StoryShuffle1'': In [[https://www.fimfiction.net/story/216813/11/story-shuffle/in-the-details "In the Details"]], a group of demonologists consult the entity known as Laplace for information, believing him to be capable of providing them with the answers they need.

* In ''Film/GroundhogDay'', Phil Connors uses his time in trapped in a GroundhogDayLoop to become an expert on whatever subject he needs to impress Rita on their repeated date to help things go well, including piano and the French language. Though due to the nature of the loop, from the perspective of everyone else, he's an InstantExpert.

* ''Literature/TheDresdenFiles'': Bob the Skull is an immortal spirit sealed inside an enchanted skull, and Harry relies on him to serve as a SpiritAdvisor. He knows much more than Harry about nearly every field of magic, since he's had hundreds of years to learn.

* In ''Literature/TheChroniclesOfAmber'', most of the immortal siblings who drive the plot just loiter around or vie against each other over Amber. Meanwhile, Benedict chose to devote his immortality to study the theory and practice of war in all its aspects. The protagonist Corwin, who's otherwise an unscrupulous [[AntiHero anti-hero]] with obvious designs upon the throne, openly says that if Benedict ever deigned to vie for the throne himself, he'd just step aside and submit.

* ''Series/TheGoodPlace'': Most the beings in the afterlife are far more intelligent than the humans they oversee, and the closest they come to death is Retirement, which is more akin to eternal torture. They are also nearly omniscient and can perform almost any task perfectly, but unfortunately, this gap in ability means they don't understand humans and can't comprehend the passage of time as humans do. This results in [[spoiler:the points system gradually becoming outdated as human life becomes more complicated, leading to every person who has died in the past five hundred years being sent to the Bad Place for punishment]].
* ''Series/NewAmsterdam2008'': John has been alive since the early 1600s, and has had so many different careers (not to mention personal experience with most studies), he's pretty much an expert in everything.

** Zig-zagged by the [[PuppeteerParasite Goa'uld]] of ''Series/StargateSG1'': they can naturally live for centuries and expand their lifespans into immortality through use of [[ImmortalityInducer sarcophagi]]... but they're not as as omniscient or as clever they'd like their worshippers to think. Their technology was just reverse-engineered Ancient tech, and the Goa'uld [[AwesomeButImpractical designed it to impress rather than function]]. Worse still, their gigantic egos and [[SanitySlippage brain-addling use of]] [[ToxicPhlebotinum the sarcophagi]] prevent them from acknowledging this. However, a rare few Goa'uld have escaped this stereotype to become genuinely inventive, brilliant, and extremely dangerous - most notably [[BigBad Anubis]], who not only has [[TechnologicallyAdvancedFoe access to unique technical knowledge]], but is also [[TheDisembodied partially Ascended]] and has no need of a sarcophagus.

** Several [[TheArchmage Archmages]] have achieved immortality and are often centuries old, if not older - to the point that many of them can no longer live on Earth without experiencing constant [[MagicMisfire Paradox]], instead secluding themselves in [[PocketDimension Horizon Realms]] deep in the [[SpiritWorld Umbra]]. Thanks to a mixture of experience and the understanding of magic they acquired just to get this far, Archmages such as these often the greatest known experts in their field of study.

** [[GodOfEvil Tzeentch]] and his forces often epitomize this trope. The Chaos God of Change and Magic, he is not only practically omniscient, is possessed of vast swathes of information on almost every conceivable subject, maintaining [[GreatBigLibraryOfEverything vast and impossible libraries of forbidden knowledge]]. His greater daemons, the Lords of Change, are masters of magic and brilliant tacticians. Mortals who serve him well may eventually be awarded with both immortality and inhuman wisdom, perhaps even ascending to become the near-omniscient Daemon Princess of Tzeentch... provided they don't go insane first.

** Dark Eldar [[MadDoctor Haemonculi]] serve as a horrific combination of [[MadScientist scientists]], [[MadArtist artists]], and [[TortureTechnician torturers]], using their mastery of technology to create all manner of hideous weapons and monsters that can be sold to Commorragh's elite. They're also every bit as immortal as the other Dark Eldar, being not only unable to die of old age, but also able to bring themselves back from the dead. The most infamous of them, Urien Rakarth, is old enough to have ''personally'' witnessed the Fall of the Eldar, and has used his arts to mutilate himself almost beyond recognition.

** It's eventually revealed that this is the reason why one notable MrExposition seems so well-informed: [[spoiler: Rose was made immortal through the power of a magical choker she wears, and not only fought in the near-mythical Dragon Campaign eleven thousand years ago, but has spent every century since then since then postponing the apocalypse as the Black Monster, hence why she knows so much about the ancient world.]]

** Another Wingly example, [[ScienceHero Savan]] was also a survivor of the Dragon Campaign, having been trapped in the city of Aglis when it sank beneath the ocean, and he's spent the millennia since then doing little else but experimenting with magic. When you finally meet him, he uses this mastery to provide you with a with a one-of-a-kind magical weapon and a flying steed that can carry you anywhere on the world map.

* Sarda the Sage of ''Webcomic/EightBitTheater'' is not only most powerful and intelligent mage in the setting, but also effectively immortal, having [[TimeAbyss lived for billions of years]] [[spoiler: as a result of a failed plan to go back in time and kickstart the beginning of the universe.]] In the present, he's essentially SeenItAll - enough to serve as an extremely manipulative guide to the Light Warriors - and he's learned enough about magic to [[RealityWarper essentially warp reality]] as well.

* The Ancient One of ''Film/DoctorStrange2016'' is TheAgeless, and while it isn't established how old she is, she's learned more about magic than any other character in the film. Essentially the epitome of the "wise eternal sage" version of this trope, she comes across as practically omniscient thanks to her study of the future - to the point that she's not even surprised when [[spoiler: a time-travelling Bruce Banner shows up on her doorstep in ''Film/AvengersEndgame.'']]

** Dark Eldar [[MadDoctor Haemonculi]] serve as a horrific combination of [[MadScientist scientists]], [[MadArtist artists]], and [[TortureTechnician torturers, using their mastery of technology to create all manner of hideous weapons and monsters that can be sold to Commorragh's elite. They're also every bit as immortal as the other Dark Eldar, being not only unable to die of old age, but also able to bring themselves back from the dead. The most infamous of them, Urien Rakarth, is old enough to have ''personally'' witnessed the Fall of the Eldar, and has used his arts to mutilate himself almost beyond recognition.
