"I laid low the warriors of old, and their like is not in the world today. Then I was but young and tender. Now I am old and strong, strong, strong..."Everyone knows a child is more durable than a newborn, and that an adult is tougher than a kid. However, for humans it stops there — we might get Older and Wiser, but from middle age onwards we begin to physically deteriorate. Some creatures... don't. They never grow decrepit. Arthritis never settles in. They keep growing stronger, faster and more resilient with each passing year, and in some cases they keep growing bigger as well. They're not simply more powerful due to having more experience: they are literally tougher than any younger specimen of the same breed. Vampires, Dragons, and Wizards are three of the most common beings to exhibit this, with ancient dragons and elder vampires possessing terrible power, and older wizards invariably commanding greater arcane might than their younger fellows. This can cause a bit of Fridge Logic if the creature is stated not to be immortal: if dragons become more resilient as they age, then just how do they die of old age? The answer could be the Square/Cube Law — except when they don't die of old age at all. A subtrope of Older Is Better. See also Monster Lords, who are often older members of their species, and contrast Evil Makes You Monstrous (for the latter, they get eviler with age and thus get uglier and stronger). For the human equivalent, see the Old Master and Badass Grandpa. See also Gigantic Adults, Tiny Babies, Monster Progenitor and Mother of a Thousand Young. Not to be confused with what happens to certain cheeses, wines, and socks.

Anime & Manga
- Joey/Jonouchi defeats an opponent by allowing his Baby Dragon to age a millennium into the much-more-powerful Thousand Dragon.
- It's also true with Yugi's Dark/Black Magician, who becomes the Dark/Black Robed Sage after also having a thousand years to study the arts of magic.
- The Gagagigo story shows that Gagagigo became stronger when he ages. However, while Gagagigo is much stronger than his child self "Gigobyte", his cyborg version "Giga Gagagigo" was modified by Kozaky, averting this trope. "Gogiga Gagagigo" was the stronger, insane version of "Giga Gagagigo", but he eventually became the good "Gagagigo the Risen" who has the same ATK and DEF as "Gogiga Gagagigo".
- The Lyrical Nanoha franchise has Voltaire, an ancient black dragon so powerful, it's practically revered as a Physical God in Caro's home planet of Alzus, with Caro serving as a priestess that it occassionally lends its power to. In contrast, Friedrich, the young dragon that Caro raised on her own, is mainly used for support fire and transport even in his full form.
- In One Piece, Lao G practices a form of martial arts that allows him to continue to gain physical strength as he ages. Problem is that it does not prevent health problems like bad backs and arthritis, which causes the octogenarian fighter to do things like destroy mountains with a single palm thrust and then collapse in back pain.
- In Kingdom Come Superman is said to be undergoing this. After so many years under Earth's yellow sun, he's stronger than ever, and immune to Kryptonite.
- Grant Morrison's Superman gets more powerful over the next 80 millennia and eventually bestows powers on his descendants.
- This has been canon of Superman for quite a while, with the explanation that as he grows older, his body becomes more accustomed to absorbing solar radiation and builds up greater stores of it. Many origin stories show his powers developing over the course of his youth, and Future Badass Superman tend to be measurably stronger (this doubles as an easy explanation for writers to develop his power further). The pinnacle of this would likely be the Superman of the non-canon story Strange Visitor, who is billions of years old and shown to be stronger than even Mr. Mxyzptlk.
- The Maestro, the future version of the Incredible Hulk, who is stronger and smarter than present day Hulk (even when PDH is in smart mode).
- Part of the rationale is that there had been a nuclear war, and since the Hulk is radiation-powered, this made him stronger at the expense of his sanity (well, at the expense of Smart Hulk's sanity).
- Explicitly stated to be the case with The Inhumans, with regards to their powers. A Kang-made Spider-Man robot once tried to disable Crystal and The Avengers by rapidly aging them, only to be Hoist by His Own Petard when Crystal suddenly had double the Elemental Powers.
- A problem to overcome in one of the XXXenophile comics. A human girl and a troll girl fall in love, but the troll is very strong, roughly on par with a bear, and liable to hurt the human in throes of passion. They manage by using restraints... but then the troll girl reveals that with age she'll become much stronger.
- Black Moon Chronicles: Dragons only get bigger as they get older. The oldest dragon in the world and the progenitor of his kind is so big that he barely fits through the spacegate.
- Keitaro in Ancestor makes Tsuruko realize that his immortality is why he has an immeasurable amount of ki. For ordinary people, the amount of ki they have eventually reaches a plateau as their body ages too much for their ki to keep growing. Keitaro is over 1500 years old and physically around 20, meaning his ki has never stopped growing.
- Sailor Moon: Legends of Lightstorm: This is stated to be the case with all Sailor Scouts, thus explaining why the Silver Millennium Moon Kingdom did not value armor as much as Sailor Jupiter would have liked.
- The Immortal Game: Applied in alicorns. Luna, the weakest of them all, is a hundred years old — due to her being imprisoned in the moon for the past thousand years — Terra is nine hundred years old, Celestia is more than a thousand years old, and Titan is more than THREE THOUSAND YEARS OLD, which puts him to Discord's level.
- This is a common assumption in most Buffy the Vampire Slayer fan fiction. Buffy and Faith, as the oldest living Slayers are portrayed as being stronger, faster, and more durable than any of the other activated Slayers, and Buffy — who has two years more experience than Faith as a Slayer — is usually portrayed as having a slight edge over her counterpart.
- One Buffy the Vampire Slayer story subverts this. Everyone thought the Slayer grew stronger as she aged but Willow discovers that they actually grow stronger from fighting. Buffy, who hasn't fought in over five years, has fallen to second strongest while Faith, who never stopped fighting, is a fair bit stronger than her. Several of the older Slayers are noted as only being a year or so before they outstrip Buffy as well.
- Due to his unique circumstances, Xander in Butterflied only becomes more dangerous as he ages. This is because he's not only The Ageless but also gains the form, skills, and memories of anyone he has skin contact with. Over a thousand years before the Clone Wars, he accidentally copies the skills of a Jedi believed to be the greatest lightsaber user ever and only gets more skilled from there. A couple decades before the clone wars, he's shown to train facing two droids/simulators that are functionally Sith lords while in use.
- According to C.C. in More than just a Man, the reason vampires get stronger with age is twofold. First, they learn new mental abilities as they age. Even at over two thousand years old, she still learns a new one every so often. Second, a vampire's Healing Factor increases as they age. Initially, they heal only slightly faster than an ordinary human but after a few centuries, they can survive their heart being impaled.
- Any Pokémon that's biologically immortal (mostly Rock and Steel types) in Traveler only becomes more powerful, and usually larger, as they age. The King Under the Mountain is an Onix that's over two hundred feet long and is the strongest of Bruno's Pokémon, despite being a relatively new member. Even more so, the First's Rhydon is over a thousand years old, can manipulate rock on a level that would make Toph proud, and is stated by Lance to be the strongest non-legendary Pokémon in the world.
Films — Live-Action
- Anacondas: The Hunt for the Blood Orchid uses this to justify Attack of the 50-Foot Whatever: the titular snakes are stated to keep growing for their entire life, thus ones that consume blood orchids — flowers that can prevent aging — can grow to be much bigger than normal.
- The vampire Elders in Underworld are stronger than any other vampire and, in some cases, can even defeat lycans in hand-to-hand combat. In a memorable example, Viktor grabs Raze in his lycan form by the throat, holds him up for a few seconds, and then breaks his neck. In the case of Marcus and William, the Corvinus twins and progenitors of the vampires and lycans, respectively, they are also stronger, although this can be attributed to Monster Progenitor. In Marcus's case, his strength is augmented tenfold after he accidentally ingests lycan blood and becomes a hybrid. William was already stronger than any other lycan. According to Selene in Underworld: Evolution, Alexander Corvinus, the original immortal and the father of the twins, is easily the strongest of them all, although he refuses to fight or otherwise make use of it.
- Godzilla's entire species falls under this. First, they start off as cute relatively docile creatures that can barely form nuclear smoke-rings or bubbles. However, as time progresses, they grow larger, more powerful, and are able to unleash powerful blasts of radioactive plasma from their mouths.
- Mothra Leo in the spin-off Mothra Trilogy falls under this big time. In the third film, he travels back in time to the Mesezoic Era where ancient Mothra Larvae encase him in a cocoon for 65 million years before he emerges as Light-Speed Mothra before transforming into Armor Mothra and killing the evil Grand-King Ghidorah. And then he transforms into the immortal Eternal Mothra his most powerful form.
- Seemingly averted in Byzantium. Clara is able to kill Werner with relative ease and wrestles Savella to the ground despite both being older than her (Savella having lived through the Crusades). It is unknown if the vampires actually have super strength or if it's just proportional to their height and weight like humans. Though Clara being able to easily overpower men to feed on them and punch through a windscreen like it was nothing suggests they are at least much stronger than humans.
- In The Zombie Knight, servants and, indirectly, aberrations. Servants gain Soul Power steadily as they become more synchronized with their reaper, and their ability will grow with practice, meditation or emergence. Aberrations grow by killing humans, so the longer that they have had to do so, the more powerful they become. The oldest and most powerful servant in the world, Sermung, is over 600 years old.
- J. R. R. Tolkien
- The Dresden Files
- It's been stated that the oldest Dragon in existence is also the strongest, though it is unknown if he is merely special, or Dragons become stronger over time.
- The undead grow stronger the older the remains that went into their reanimation are. This culminates with Harry reanimating a Tyrannosaurus' skeleton. A Curb-Stomp Battle ensued.
- Black Court Vampires. On the one hand, it is noted that since Mavra is such an old vampire she is likely to be mobile and capable of defending herself during the day where younger vamps would be forced to sleep. But then they toy with it by pointing out that the reason Black Court vamps in general are such major badass types is because of basic survival of the fittest since Dracula was published. To get to be that old, they must have been Badass to begin with, or they'd have been killed (again) years ago.
- Wizards also follow this rule — while part of it is that they learn how to more effectively use their power, even an increase of skill can't account for ALL of the tricks that more powerful wizards can pull off. Even WITHOUT the various external power boosts he gets, Harry has gained a noticeably greater degree of power over just the decade that the stories take place over; and significantly older wizards on the Council are capable of tricks Harry didn't even know were possible like dropping satellites from space with pinpoint accuracy and turning into a half-dozen animals in a bout with an Eldritch Abomination. This is aided by a wizard's slow aging and ability to eventually regenerate from even serious maiming without a build-up of scar tissue.
- Also, Wizards minds are subject to this. The older they get, the more resistant their mind is to any type of mind control or persuasion. This little fact is used to great effect in one of the novels.
- In The Cinder Spires, by the same author, core crystals conduct energy more and more efficiently as they age. Makes for a minor moment of awesome when Predator is revealed to have what may well be the oldest core crystal in the world.note
- The basilisk from Harry Potter and the Chamber of Secrets is apparently still in top form at the age of one thousand. And if the shed skins are any sign, she's still growing.
- Dragons in Inheritance Cycle never stop growing, some were as big as mountains.
- The vampires in Anne Rice's The Vampire Chronicles books get stronger as they age. Even after doing nothing but sleeping for hundreds of years, they wake up stronger than they were before. Drinking the blood of an older, more powerful vampire can also add to their power. They also obtain new abilities with age, or "gifts" as they call them, the most common one being the Cloud Gift which enables flight. Interestingly, no vampire is ever comfortable with flying, realizing how unnatural it is (even for a vampire), except for Akasha and Lestat (who gained these abilities after drinking her blood).
- Eventually subverted in Mikhail Akhmanov's Arrivals from the Dark series, where the Dromi continue growing as they age, which initially does make them stronger with age. However, as they reach about 120 years old, the Square/Cube Law takes into effect, making it very difficult to move, and they eventually get crushed by their own weight.
- The vampires in Barbara Hambly's Those Who Hunt the Night and sequels grow tougher as they age, eventually becoming resistant to their weaknesses - an ancient vampire such as Brother Anthony the Minorite can withstand the touch of silver that would burn and sicken a fledgling (newly created vampire) with even the slightest contact and even resist the light of the sun and the irresistible sleep that forces all younger vampires into a coma during the daytime hours. Their psychic powers (and presumably physical strength) also increase with age, although there are also possible, though inconsistent, degradations with age (the Bey of Constantinople, for example, can no longer create fledglings on his own).
- In the Wiz Biz series by Rick Cook, dragons grow larger and more powerful with age, and have no known natural upper limit to their lifespans.
- The Nobility in the Vampire Hunter D universe are also like this; and since the series takes place in the far future circa 12000 AD, where most of the time between now and then was dominated by vampiric rule following a nuclear Armageddon 20 Minutes into the Future, some are very old indeed. Downplayed in that a recent human uprising wiped out most vampires, and that those remaining, for all their terrible power, are a dying race. One of the recurring themes of the novel is that while humans are, on the whole, weak, short-lived, and otherwise flawed, vampires have an even greater, fundamental flaw which dooms them to eventual extinction; as the Revered Ancestor once put it when speaking about his kind, "Transient guests are we." It just so happens that D himself is the most successful result of a cross-breeding program by his father (the aforementioned Revered Ancestor) aimed at creating a new breed of vampires without this flaw, thereby ensuring the species' continuance.
- Trolls in Discworld are theoretically immortal, but as they get older they get bigger and slower and tend to be more inclined to sit and think. They call this "getting philosophy". Eventually they just stop moving altogether, gradually "decomposing" or eroding into an oddly shaped heap of minerals with a tiny living spark in the center. Many of the Discworld's mountains are actually very old trolls. Shown to be true when a troll warns a character about his grandfather, who is one of the mountains and is very annoyed when some adventurers light a campfire in his mouth.
- Darklings from the Midnighters series grow much, much stronger with age. Of course, they also get crazier with age.
- In Tales of Kolmar, the Kantri grow throughout their lives, molting their armor every fifty years or so. The Eldest in that series, Shikrar, is over eighteen hundred years old and the largest of them, as well as a good fighter and the best flyer - though that last can't be attributed to his age, he became the best flyer and held on to that distinction from a much younger age. On their own Kantri reach about two thousand years before they die, which isn't discussed but it seems to happen fast. It's also noted that some grow "old before their time" and start to mentally slip; Shikrar suspects that another Kantri is one of these and guiltily wonders if he'll die in his sleep well before the two thousand mark, as these often do.
- Inverted in David Wellington's 13 Bullets (and sequels). A vampire is never as strong again as it is its first night. They gradually grow more decrepit, requiring more and more blood to stay active. Older vampires are a threat because of greater experience and because their vampire progeny protect and feed them.
- Queens and Consorts in The Books of the Raksura grow larger and stronger with age; Moon has to inform his peers when they meet an elderly Islander that most "groundling" races don't do that.
- In Robin McKinley's Sunshine, this appears to be true of vampires, with some twists. Classically, in-setting, an old vampire is a master vampire, and very, very strong — their mental powers become vastly more potent, allowing them to accrue minion-vampires. However, the longer they survive in that way, the less capable they are of enduring sunlight, until even moonlight is crippling and they can't even speak the word. Hence the minions, who join in the hopes of gaining power themselves. The main character discovers through a relatively Friendly Neighborhood Vampire that it is possible to become equally powerful, maintain independence, and never create or join a gang... but the gang-leaders don't want their minions finding that out, and even if they did, they may not be interested in tightening their moral standards.
- The Night Huntress novels have a variation on this: age brings power, but how much depends upon the vampire. Some take centuries to become masters, while others reach that level in a few decades. When Cat first fights Ian and learns that he's around 200, she comments "You're strong, then. I've met 700-year-olds who don't hit as hard as you do."
- The Immortals After Dark series' titular beings.
- Likely inspired by the Tolkien example, dragons in A Song of Ice and Fire never stop growing as long as they have freedom and food. Captive dragons reach an upper limit depending on the space constraints of their environment. It's unknown whether they ever die of old age or disease, but until they die, the older, the stronger. Historical dragons such as Balerion the Black were massive because they lived for quite some time and were uninhibited during their lives, but future dragons were hindered by the Dragonpit in King's Landing until they died out altogether. In the present day, Daenerys' dragons are of differing sizes due to this as well. Drogon flew off into the wild and grew to be colossal in size, whereas Viserion and Rhaegal were kept in the basement of the Great Pyramid of Mereen, and are considerably smaller than their older brother.
- In The Jungle Book, it is mentioned that Kaa the Rock Python owes his great size and strength to the fact he's over a hundred years old, and he's still in his prime and growing. In the story "The King's Ankus", Mowgli meets a cobra named White Hood of a similar age, size, and strength to Kaa. However, while White Hood has great size and strength, his body stopped producing venom and he's gone senile.
- Koloss in Mistborn are like this; they never stop growing larger and stronger throughout their lives, and elder koloss (approx. 20 years) are around fifteen feet tall and incredibly dangerous opponents. They don't get much older or bigger than that, though; in a nod to Truth in Television, if battle doesn't kill them, their massive size causes heart failure.
- Vampires work this way on Buffy the Vampire Slayer. Older vampires become stronger, tougher, and more demonic in appearance, and may pick up other powers, like Dracula's tricks. When Spike is first introduced, Giles initially dismisses him as a big threat when he discovers Spike is scarcely over 100 years old (shortly after, he discovers Spike's full history and reconsiders). Kakistos was noted as being an extremely old vampire and thus a bigger threat. His age meant he had lost most traces of a human appearance and a standard size stake wouldn't do the job, so Faith had to use a two-by-four to finish him. The Master (referred to as "the oldest vampire on record") was another vampire old enough to have stopped looking human, and had somehow gained the power to open the Hellmouth. The Master also took a larger-than-usual stake, dying when he was impaled on a broken table leg. And unlike other vampires who turn completely to dust when killed, the Master's skeleton remained intact. Until Buffy smashed it with a sledgehammer to prevent his revival in a ritual. Notably, the Master's inhuman appearance closely resembles that of the Turok-Han or "ubervamps" ("pure" vampires rather than former humans) of Season 7, leading some to speculate that he was the very first human to be turned into a vampire.
- In a curious aversion, the vampire who called himself The Prince of Lies was, like the Master and Kakistos, very old and extra demonic in appearance, but seemed rather weak; Angel killed him easily. This might have been due to the element of surprise, but you'd think such an old vampire would have better reflexes.
- While age is a major favor in vampires' strength, bloodline seems to matter too. Spike, while not at all ancient, is by bloodline just 4 generations removed from the Master.
- Pretty much the same in My Babysitter's a Vampire. The three teenage vampires in the main cast are pretty much incapable of winning a fight against older more experienced vampires under normal conditions. But they are able to get through difficult fights with team work and determination.
- In Moonlight, Mick senses (or rather smells) that Lance is very old, who further reinforces this by jumping from a tall building (impressing even Mick) and surviving being burned (any part of a vampire that touches fire is normally instantly turned to ash). Coraline also somehow survived being trapped in a burning building and could move with a stake in her chest, which is normally impossible. By contrast, the 700-year-old Lola was pretty handily defeated by Mick, despite being able to move much faster than him, and one of her past careers was a Pirate Girl.
- Lance and Coraline are able to survive fire because access to a temporary cure to vampirism, that was used during the French Revolution. Many of the French Royalty and Aristocratic class were vampires. The Revolutionaries would test them with fire and if their fingers turned to ash, they would be beheaded. The cure made from an now extinct plant, allowed the vampires to mimic humans including burning without turning to ash.
- In The Vampire Diaries vampires all become stronger as they age, although the difference can be overcome through numbers, surprise, anti-vampire weaponry, or other tactics. The oldest of them, the Originals, get a whole bunch of nifty powers and are next to impossible to kill. When they did manage to take one down, he would only remain dead as long as the magical knife that killed him wasn't removed, and his body remained indestructible.
- Vampires from True Blood. Battles between vampires are always determined by how old each vampire is. Even the difference of about a year makes all the difference. They also seem to develop the ability to fly over time. However, their weaknesses also get more severe. A 2,000 year old vampire will burn up in the sun within seconds, whereas a younger vampire will take minutes.
- Faeries also become more powerful with age. Their skills and power with photokinesis, telepathy, etc improve over the centuries.
- Being Human: This seems to apply to vampires, ghosts and werewolves.
- Vampires. While Old Ones still can be killed as easily as any other Vampire, they have a lot more "tricks" under their belt, with some such as Wyndham being able to casually enter without an invitation, something that would cause most Vampires to instantly begin to boil alive. Some physiological changes seem to occur with age as well. Mr Snow, the leader of the Old Ones, has developed a sickly pallor, rotting teeth and protruding black veins due to his advanced age, and had Super Strength far beyond that of younger Vampires and Werewolves, being able to tear a man's inner organs out with his bare hands.
- Ghosts are also stated to get stronger with age. Most however fail to get that far due to losing their connection to the mortal world, leading them to simply fade away into non-existence.
- Werewolves age normally, but they get stronger every time they turn. A werewolf who has been changing for years will be able (when transformed) to kill vampires with his bare hands.
- Forever Knight worked this way. Lacroix was able to survive being impaled with a burning stake, and both Nick and Janette were also more resilient than many younger vampires. Also, Lacroix got his butt handed to him by his "vampire mother", who was a teenage girl when she was turned.
- On Supernatural, every species that's older than yours is more powerful. One of the oldest species, Leviathans, trump almost everything in their strength and dexterity, and the mother of all monsters, Eve, has the ability to rob an angel of its power.
- Smallville: As the years/TV seasons go by, Clark gets stronger and more powerful. Just compare Season 1, when gunfire bruised his skin, to Season 5, when he survived atmospheric reentry without a scratch.
- The Doctor Who episode Father's Day says that, temporally speaking, older is stronger. The episode's Clock Roaches are unable to devour a centuries old church, and when they get in thanks to a paradox they immediately are drawn to The Doctor due to being even older than the church.
- Appears to be the case with the Ultras from the Ultra Series. While some younger ones are prodigies, generally speaking the more ancient an Ultra the more powerful they are. The Father of Ultra and Ultraman Belial are both in the 150,000 year range, and so powerful the number of beings capable of fighting either one on one and at full strength can be counted on one hand. The two oldest Ultras (that were actually active their entire life time at least) are over 300,000 years old Physical Gods.
Religion And Myths
- Japanese Mythology:
- In Japanese folk thought, foxes (Kitsune) grow a new tail for every hundred years they live, with a proportional growth in power, to a maximum of nine, at which point they're pretty much Physical Gods.
- In fact, there's a whole subgroup of Youkai / Obake called Tsukumogami (kami of a tool) who were former ordinary objects or animals who acquired supernatural powers and sentience after being used/living long enough (usually about a century).
- Dungeons & Dragons has this happen to many creatures. Vampires, dragons, liches and others tend to grow more powerful as they age. The Ravenloft setting is especially keen on doing this with The Undead. Pictured above are red dragons. For the record, the second largest one is an "adult". The top one is an ancient.
- Warhammer and Warhammer 40,000 contains plenty of examples, and though many are due to the "more experience" version many others fit this trope.
- Orcs/Orks grow larger, tougher and meaner with age, the oldest being hulking monstrosities even by their standards.
- Lizardmen are full of this (but see Real Life, below). Slann and Saurus don't die of old age at all, and the latter species (along with some of the non-sapient monster species) also get tougher as they get older. Really the only thing controlling their population is that Slann have an incredibly slow spawning rate and Saurus have an incredibly high death rate. note
- A more minor example, Space Marines seem to grow in size along with rank and age. It is theorized they practically never stop growing, though it will lessen.
- Less noticeably, although dwarves do not get larger with age they do get notably tougher until they are near death.
- In the Munchkin card game, "Ancient" is a +10 monster buff.
- The World of Darkness
- Vampires in the Old World of Darkness game Vampire: The Masquerade are stronger with age in two ways: experience and Generation. Older vampires are more experienced (obviously), have more and stronger Disciplines than neonates, and have influence over vampiric and human society. A vampire of lower Generation is closer to the blood of Caine than a 13th-Generation neonate (the game's "default" new player characters), increasing their stat caps and allowing them to spend more Vitae faster. And going even further, it starts getting scarier: There are sleeping vampires that were embraced before the Great Flood. They're strong enough that, when one of them woke up, large-scale orbital weaponry was needed to put it back down.
- In Changeling: The Dreaming, trolls become physically larger and stronger as they age.
- Masquerade's successor game in the New World of Darkness, Vampire: The Requiem, subverts this with its Blood Potency stat. Like Generation, higher ranks of Blood Potency allow a vampire to spend more Vitae and have higher stats, but can't regain Vitae from animals and eventually humans. Instead of being a simple "I'm stronger than you" score, high Blood Potency invokes a psychological need to enter torpor, during which the vampire's Blood Potency drops and he forgets his experiences (the so-called "Fog of Ages"). Ergo, no Kindred stays stronger with age, since they depower while in torpor and their memories become faded dreams. Methuselahs, however, do not suffer the Fog of Ages. With the right Coils of the Dragon, it's possible to utterly avoid the increased blood thirst that comes with age. Meaning in a few centuries, we might have Blood Potency 10 blood gods running around that can still feed on humans rather then other vampires...
- Mummy: The Curse, however, is an inversion of this trope — a mummy rises at the peak of their power, but it quickly drops a rank and then starts to level out until it's at its weakest, which is when the mummy needs to go back to rest.
- In fantasy-steampunk RPG Wolsung Steam Pulp Fantasy, trolls fall under this trope without exceptions. When they are about 50 years old, they start to burn out mentally, fall into fits of rage, and at some point they hulk out. Permanently. From this point, they become larger, more resilient and feral with age... and nobody ever checked just how old they can get. Usually, their family or the authorities will put them down shortly after the onset of this freakish senility. It's less pronounced with troll women, who don't lose so much of their brains - just their morals.
- The potential for power of Exalted is tied directly to age, with caps placed on their highest potential Essence based on how long they've lived (although there are a few magics that can break this). The highest levels of power are only available to Exalted who are more than a thousand years old. Due to the Great Curse, this also means that the ones with access to the high Essence charms are also the most likely to be utterly insane, driven mad by the Curse, and rather prone to even greater acts of madness while in Limit Break.
- One scenario in Betrayal at House on the Hill reveals the house to be alive and capable of draining the inhabitants' life, making them age rapidly. (With the exception of the Traitor, who brings victims to the house in return for eternal youth.) Character stats start dropping rapidly once a certain age is reached, but the youngest characters actually get a stat boost for a while as they become grownups.
- Dragons in Magic: The Gathering. Dragons only get bigger, stronger, and smarter as they age. The last Elder Dragon, Nicol Bolas, is an incredibly dangerous villain who is "Dominaria's most ancient evil." They apparently can die of old age eventually, since one of Nicol Bolas' goals was to regain the immortality he lost when his Planeswalker Spark was weakened by the Mending.
- Fallout 3 Super Mutants grow stronger (but not smarter — the opposite is implied to be the case) with age. Super Mutant Brutes are younger and weaker than Masters, who are weaker than Overlords, who are weaker than Behemoths, who are the oldest. Not that this particular trait is not (explicitly) shared with their west coast counterparts.
- In fact, in Fallout 2 the Super Mutants of Broken Hills are said to be slowly going weak and senile. This is probably due to being infected with a different strain of FEV (found in the Mariposa Military Base) than the mutants in the Capital Wasteland, though when the Courier encounters some of those same mutants in the Mojave, they seem to be as strong as ever.
- Even the Capital Wasteland Mutants don't all follow the rule — it is heavily implied that Fawkes, one of your companions, was one of the first East Coast Super Mutants, yet he's still a regular Super Mutant (albeit a supremely overpowered one if you've got Broken Steel installed.) This may be tied to the oddities of his transformation; he's one of the very few to fully hold on to his sanity and morality.
- Fallout 4 Super Mutants are similar to Vault 87 Super Mutants, with Behemoths being the biggest and the dumbest, its mind buried under primitive rage. Far Harbor has Gulpers mutant salamanders that get bigger and hungrier as it gets older, the largest of which can swallow a person whole.
- The asari in Mass Effect are said to show this, at least with regards to their biotics, which grow in power as they reach the matriarch part of their life cycle. Kaidan Alenko suggests that this is not restricted to asari, noting the increase in his own biotic abilities over the previous three years. Similarly, krogan continue to grow larger and stronger with age. Of the three krogan who join up with Shepard and Ryder, two of them are well over 1000 years old.
- A few of the legendary Dragon-type Pokémon count, but the very old Rayquaza stands out the most. Although it had lost nearly all of its teeth through the decades, it still flies and battles as if it hasn't aged a bit. Not to mention its high attack stats. The Creation Trio have special mention here, since they literally created the universe itself and still live on to present day. Although, that's probably because two of them are literally gods, while the third one is undead.
- Dragon Age:
- Dragons only get more powerful with age. The Darkspawn also demonstrate the same is true of them, with a mini-boss Hurlock Vanguard in the Deep Roads called "Ancient Darkspawn."
- In Dragon Age II Legacy, there's Corypheus, the most ancient Darkspawn (or at least, one out of half a dozen of them).
- The same could be said of the Grey Wardens, due to the Darkspawn Taint within them getting stronger over time (at least they seem to understand the Darkspawn better). However after 30 years, they gradually start to go insane as the Taint turns them into Ghouls.
- Some of the monsters in darkSector are stated as getting larger and stronger with age. Just before a boss fight, an ally warns you, "This one is very old!"
- The Elder Scrolls:
- While there are some regional variations in exactly their powers work, vampires tend to play this straight. Throughout the series, vampires tend to be The Ageless (though if they go long periods without feeding, they tend to be come irrevocably insane and feral). Vampire "Ancients" are the oldest and strongest vampires in Tamriel. Skyrim's Dawnguard DLC introduces Vampire Lords, Tamriel's oldest vampires who received their vampirism directly from the Daedric Prince Molag Bal, the patron of vampires.
- In terms of their religious beliefs, the Altmer (High Elves) invert this trope. They believe that the other "lesser" races of Mer (Elves) are the result of "degeneration" over the ages, with each generation being weaker than the last as they are one more removed from their Aedric/Ehlnofey ancestors. The Altmer actively try to breed themselves back into their ideal, which includes killing undesirable progeny. (In their minds, they are releasing the soul so it has a chance to be reincarnated in a better form.) And don't even get them started on the races of Men...
- In League of Legends, the Voidlings created by Malzahar grow more powerful every six seconds. Eighteen seconds after they are created, they just die.
- While many characters are powerful due to winning the Superpower Lottery, many more obtained it seemingly by virtue of being around for so long. 500 year old Remilia is almost as powerful as her sister Flandre, despite the latter possessing the second biggest Story-Breaker Power in the setting. Kanako and Suwako are more than 2300 years old and with power worthy of their station, despite the years with barely any faith to sustain them. Yuuka is noted as one of the oldest living youkai, as well as one of the strongest, despite her explicit ability being making flowers bloom and face the sun. Eirin is a Time Abyss and quite possibly only surpassed in power by Yukari, with even the Watatsuki sisters respectful towards her. And Fujiwara no Mokou is a human who is now EX-Boss strength, due solely to the immense amount of time she has to practice.
- Ran Yakumo is a Kitsune and Chen is a Nekomata. Both are Youkai who were originally animals, but grew stronger with centuries of age.
- Woses in Battle for Wesnoth. Elder and Ancient Woses are stronger than normal ones and sapling.
- Nym, from the Star Wars Starfighter series, is a Feeorin, who are specifically noted to grow progressively stronger as they age. And since they can live as long as four hundred years, that's quite a lot of room for growth. Because of this, their society is ruled by "the Exalted" who is simply whoever is the oldest living Feeorin.
- Liir from Sword of the Stars have this; the older they grow, the larger they get and the more powerful their psionic abilities become. The only thing limiting their size, and eventually causing their death, is the Square/Cube Law. Of course, some didn't like that last bit, preferring to enslave the younger ones to make them build spacesuits for them, so they could live in space and remove that last limit on their immortality. Very few remain of those who did this, but just one can wreck whole armies.
- Dragons in Castle of the Winds, with "Ancient" ones the strongest of all.
- Legacy of Kain: Vampires "evolve" over time, occasionally entering a cocoon-like state and emerging changed; Typically stronger and with new abilities, as well as less human. But Kain's spiritual and mental corruption caused his descendents to eventually degenerate (or something similar). It's implied that a vampire's evolution conforms to his personality; Vorador's chin horns used to be a similar beard, human Rahab's armor had a seahorse painted on it, and Raziel told Zephon the latter's final form is a true representation of his soul. It's revealed in Soul Reaver 2 that some changes, like the typical three-fingered hands, are the turned vampires becoming more like the originals.
- Guilty Gear:
- Slayer is a Nightwalker who is several hundred years old, the original founder of the assassin's guild, and one of the most powerful characters in the series. It's heavily implied that he's holding back on the whole cast; even if you utterly destroy him in a fight, he'll just lie on the floor with his head in his hand, casually chilling out.
- Jam Kuradoberi, who is told after fighting Slayer that given enough time, she'll end up surpassing him.
- The Last of Us has an interesting example. The infected in this game are, well, infected, so most of them don't live for very long before dying and become spore fountains. For the handful that do survive in the long-run, though, they become more dangerous with age. Newly-turned Runners aren't able to do all that much damage, and neither are Stalkers, although they're more stealthy. After a few months to a few years, though, the infected become Clickers, who can easily one-hit the player. The oldest infected, probably from the initial outbreak twenty years ago, grow to be Bloaters.
- Dragons in Final Fantasy XIV are shown to be not only really freaking old (some living for hundreds of years and a few even reaching a thousand or so), but they get bigger and stronger as they get older. Dragons, especially the older ones, can also recover from nearly any wound and injury by simply just sleeping it off.
- The titular creature in Project Wight grows larger and more powerful with age, in addition to developing new and deadly abilities.
- Immortals from El Goonish Shive continue to get older, smarter, stronger, more bored and less sane until the point comes where they basically become People Of Mass Destruction. To prevent this, they voluntarily undergo a kind of ritualistic death/rebirth cycle every couple of centuries to lose most of their power and memories so they can start over and keep things interesting. A significant portion of the latter half (after the death of Damien) of the story is driven by Pandora Chaos Raven, an immortal who refuses to let go of her accumulated power, and seems to be approaching Eldritch Abomination territory.
- In Girl Genius Jägermonsters become bigger and less human-looking as they age. We get a better look at these changes when Vole is artificially aged a few hundred years and he goes from looking like a big guy with white skin, black eyes and small fangs to being maybe half again the size he was before, with spines protruding from his now green skin, and having sprouted a tail. As a result, a threat that would take a huge platoon of regular Jägermonsters to handle can be trounced with no losses by four of the centuries-old generals.
- The reason the Elite Vampire Council in Charby the Vampirate are trying to recruit the eponymous vampire is that he is older and stronger than any of them.
- Mumm-Ra on ThunderCats (1985) is the Big Bad partly because he's a thousand years old.
- In Avengers, Assemble!, an Infinity Gauntlet-powered Thanos uses the Time Stone to instantly age most of the Avengers into dust. When he tries it on Thor, Thor just grows a Badass Beard, declares he's now even stronger, and smashes the Time Stone with Mjölnir, turning its effects back on Thanos and forcing him to undo all of it.
- In Zevo3, this is the reason the Zevo compound works better than it did when Stankfoot first created it. He even lampshaded it.
- My Little Pony: Friendship Is Magic:
- The Alicorn Princesses seem to function under this rule. Twilight and Cadance are definitely a step above the average pony, but are still fairly young and aren't that much more powerful. Celestia and Luna, on the other hand, are each at least a thousand years old are so powerful that their primary responsibilities involve manually moving the Sun and Moon around.
- Very likely the case with dragons. Teenage dragons are only a bit bigger than ponies; adult dragons are huge monsters that are better left alone. Dragon Lord Torch, the biggest dragon of the land, is pretty much mountain-sized. A story sets a thousand years in the past (episode "Campfire Tales") show a dragon very similar to Torch, but smaller (the size of an adult dragon). If it's indeed Torch, it demonstrates dragons are not only very long-lived, but never stop growing.
- Avatar: The Last Airbender: the oldest Earthbender seen (Bumi) is past 100, is built like the Hulk, and has mastered his art to the point where he only needs his chin. Meanwhile, Toph Beifong is blind, invents metalbending at age 12, fights Bumi to a standstill (the match was interrupted because they were causing quakes that gave away their position)... and 70 years later, no longer needs to move her arms to bend, curbstomps the Avatar, and is able to pull a Nonchalant Dodge against airbending.
- Truth in Television: Gustave the Crocodile is over 66 years old, believed to be over twenty feet long and two thousand pounds heavy, and still killing people and even hippos.
- Trees, sequoia in particular.
- Lobsters are a perfect example. According to recent research, a lobster does not weaken or slow down with age. In fact, it becomes more fertile as it gets older compared to younger lobsters. Barring injury, disease and capture they can live on indefinitely, reaching impressive sizes. All this is attributed to telomerase, an enzyme that repairs DNA sequences of the form "TTAGGG".
- Reptiles in general. Most animals reach a certain size and stop growing. So long as a reptile doesn't get killed or die by other means it just keeps getting bigger and bigger as it ages. Of course, they still die of old age at some point, and in many species growth is so slow later in life that it can be almost imperceptible.
- Sharks. It is believed that some great whites still swimming the seas today are centuries old. A great white shark is believed to keep growing until it's killed, and since any that die of old age are likely to get eaten before humans can look at themnote it's anyone's guess how long they live.
- Most animals, really. Mammals, with their short stage of rapid growing, limited reproductive life and only two sets of teeth are the exception, not the rule.
