* ''Manga/{{Bleach}}''
** Pictured on the main page: Genryuusai Shigekuni Yamamoto. [[TheCaptain Captain]] of the First Division, creator of the modern two-thousand-year-old Shinigami Academy (yes, he really is that old), he's been [[TheGeneral Captain-Commander]] of the entire [[AuthorityEqualsAsskicking Gotei 13]] for [[AsskickingEqualsAuthority a thousand years]]. He has the most powerful [[PlayingWithFire fire-based]] [[EmpathicWeapon weapon]] which doubles as the [[ThePowerOfTheSun strongest offensive power]] of ''any weapon'' in the series to date. Despite his aged, scarred appearance, he's incredibly [[ElderlyImmortal toned and well-muscled]]. He can outpace Shunsui and Ukitake easily (both considered brilliant in their own right) and take them both on in his primary release form without breaking a sweat. He has a [[PillarsOfMoralCharacter stern sense of justice]] and will [[HandicappedBadass sacrifice his own limbs]] in battle without hesitation. Even the InvincibleVillain fears his strength. In short, he's a StoryBreakerPower. The only one that doesn't fear his strength is his thousand year ArchEnemy [[TheEmperor Yhwach]] [[spoiler: who proves his own badass credentials by stealing Yamamoto's [[SuperMode bankai]] and ''killing'' him. However, he was still only able to do so through misdirection and after stealing Yamamoto's bankai.]]
-->'''[[MalevolentMaskedMen Masked Invader]]''': "I am surprised. It was quite easy to break into this room. Despite it being the office, or better, the personal room of the Captain-Commander of the Gotei 13. Isnít security a bit too soft?"
-->'''[[BadassBoast Yamamoto]]''': "There is no need to worry. I am here. There is no better security than this."
** Arrancar version: Barragan Luisenbarn, owner of a [[AnAxeToGrind frigging huge axe]] and with the power to [[spoiler:age anything he touches or breathes on into nothingness. Barragan was "King of Hueco Mundo" before Aizen arrived.]]
* Jack Rakan from ''Manga/MahouSenseiNegima'' is somewhere around 70 years old, but he is easily the strongest member of the cast after the centuries old Evangeline. He can fight an Ancient Dragon to a draw, blow up mountains by accident and survive getting hit by the magical equivalent of a ''tactical nuke''. [[spoiler: Plus thrashing a NighInvulnerable RealityWarper without much trouble and ''willing himself back into existence'' after being erased.]]
** Members of Rakan's race live much longer than humans. If memory serves right, Rakan would be in his mid-thirties in human years.
* Joseph Joestar in ''Manga/JoJosBizarreAdventure'' Part 3. He may not get as many action scenes as he did in his youth so as to make place for the new protagonist, but he still displays his characteristic cunning (perhaps more than any other JoJo, he won his fights by outsmarting his opponents) by completely turning the tables on both the Empress and Mariah/Bast. Not in Part 4, though, where he is, indeed, too old and frail to still qualify as a Badass (though he doesn't lack courage at all, as proven in the Achtung Baby episode).
* ''Manga/{{Naruto}}'':
** The Third Hokage is a bit of a subversion. While he does have a mastery of jutsu that Orochimaru can't begin to match, the ANBU members observing the fight realize that the Third has less chakra than he did in the past due to his old age. [[spoiler: This is one major reason the Third had to resort to a HeroicSacrifice to stop Orochimaru]].
** Jiraiya also counts, being around 50 at the time of his introduction, as a Kage-level ninja who spends his time writing porn and perving on young women.
** There's also Jiraiya's former teammates Tsunade and Orochimaru, who are also in their 50s. The former is a [[NeverMessWithGranny badass grandma]] ([[BerserkButton just don't call her that]] unless your name is "Naruto Uzumaki"!) with super-strength and incredible medical ninjutsu skills that make her near-impossible to kill, even when she's [[spoiler:cut in half at the waist]]. The latter may be a MadScientist EvilOverlord, but he's also the most talented ninja of the trio (and is possibly even more resistant to physical damage than Tsunade), being able to easily hold his own against high-level opponents [[spoiler:even without the use of his arms.]]
** Danzo. Although, at the age of 72, he normally appeared to be a frail old man, Danzo was actually an extremely powerful ninja. He was able to easily kill several would-be assassins and was able to fight on the same level as Sasuke.
** Chiyo is a [[NeverMessWithGranny badass grandma]]. She's a 70-ish year old war veteran who's a specialist in poisons and a skilled puppeteer. With the help of Sakura, she managed to beat her grandson Sasori, perhaps the strongest ninja ever produced by the Hidden Sand Village, and his army of puppets. She used '''10''' puppets against his '''''100'''''!
** The Third Tsuchikage, Onoki of Both Scales, stands above them all. Despite being one of the oldest (mortal) characters in the series, he's still strong and fast enough to give modern-day shinobi an ass-kicking. In chapter 515, he's seen easily carrying an enormous island-sized turtle (one large enough to support its own ecosystem, complete with smaller but still very large animals on its back) with one hand thanks to his weight-decreasing jutsu.
*** He even stops Madara's ''[[ColonyDrop Meteorite Attack]]'', [[spoiler:though he can't quite halt the second one.]]
*** The position of Kage has a very high mortality rate. Yet, he's the only active-duty ninja from Hiruzen's generation who has managed to live this long so far.
** Hashirama Senju. Loving grandfather who spoiled his grand kids and OneManArmy who's widely considered the most powerful shinobi after the Sage of Six Paths.
** Let's not forget Kakuzu, the Akatsuki member, S-rank criminal shinobi that is '''91''' years old, and yet he can make his body hard as rock, can move incredibly fast, can '''rip out''' his opponents' '''''hearts,''''' and has mastery over ALL of the jutsu elements! Being incredibly handsome is a plus.
* ''Franchise/DragonBall''
** From [[Manga/DragonBall the original manga]] onwards, Master Roshi, the man who taught Goku his most powerful regularly used technique, was one of the very few people to beat Goku in a fight, and one of the most powerful humans alive at the beginning of the story, and at the end is still #4 or #5. Of his three latest students, two take the "strongest human alive" spot, and the other becomes "strongest anything anywhere", except perhaps for ''his'' own son.
** Taken literally in the end of ''Dragon Ball Z'' and all of ''Anime/DragonBallGT''. With Pan, Goku is a grandpa, and he's always been badass. Granted, he's not old, it's kinda made comical when [[spoiler: he gets turned into a kid in DBGT. He's a Badass Grandpa who looks like he's 6.]]
* In ''Anime/TengenToppaGurrenLagann'', we have Lordgenome. He looks like your average guy...or, uh, your average bodybuilder, not like he's over 1000 years old. However, in the final fight of the first story arc with [[spoiler: Simon, after his mech gets wrecked, Lordgenome pops out of the cockpit and beats the crap out of Lagann bare handed. He eventually lost, and had his final monologue without a heart, lungs, etc.]] Later, [[spoiler:he's brought back as a bio-computer, Futurama head-in-a-jar-style. In the final fight of the second story arc against the Anti-Spiral, Lordgenome first recreates his body and his mech from nothing]] in order to do battle. He holds back the [[spoiler:Anti-Spiral's Infinity Big Bang Storm, an attack on par with the creation of the universe, eventually being disintegrated on a quantum level. However, he actually ''absorbs'' the attack and turns its power into pure Spiral Energy, to give to the good guys]] as his final Badass Grandpa act. It's a shame, he was content to sit on his throne for the rest of his immortal life, ruling Earth, having an infinite number of mistresses, but those silly protagonists forced his hand...\\
\\
Lazengann, the personal mech of said Lordgenome, can be considered a Badass Grandpa HumongousMecha. Despite being at least one-thousand years old, it is far from rusty and clunky, [[BareFistedMonk it kicks ass using kung-fu]], and [[spoiler: defeats the once-undefeated Gurren-Lagann]] with only a shredded hand to boot. The only reason it [[spoiler: was defeated by Simon in Lagann was because of Simon's superior Spiral Power compared to Lordgenome's.]]
* In ''Manga/ThePrinceOfTennis'' manga, Tezuka's grandfather Kunikazu is in his 70s, but ''still'' has incredibly sharp reflexes (is able to use chopsticks to catch a falling teapot) and is one of the most respected (if not feared) instructors in the Tokyo Police Academy.
* ''Manga/HajimeNoIppo''
** Genji Kamogawa and Jinpachi Nekota. Both are in their 70s and retired, but still have impressive strength for their ages.
--> '''Kimura:''' (after seeing them exchange blows as a greeting)...''THAT'' is how old men fight? Wow!
** Their friend and rival Dankichi Hama also fits.
* GhostInTheShell: What's Aramaki's response to being captured and put at gunpoint? Call his captors dumbasses and order them around. And they ''listen''. As does Section 9; an elite team of combat cyborgs, without serious question and with utmost respect, obeying a smallish older man.
* ''Anime/MobileFighterGGundam'': Master Asia. Taking out a HumongousMecha with only a loincloth (ON FOOT!) may be [[HowUnscientific unscientific]], but it cements his badassery and he follows up with much more feats of bad ass. ''Look! The east is burning reeeed!!!''
* CrossboneGundam: Grey Stroke, an elderly [[Anime/MobileSuitGundamZZ Judau Ashta]] is possibly the best pilot in U.C. While everyone has their claim to fame, Grey Stroke can admit to living until 80 years old, piloting the Gump(a broken ZZ Gundam with a PEG LEG and barely any of the original parts) and defeating ZANSCARE EMPIRE MOBILE SUITS despite a tech difference of 60+ YEARS. To put in perspective how badass that is, imagine taking on F-22 Raptors with a makeshift-customized P-51 Mustang and ''winning.''[[note]]The Gump may be an ancient machine with jury-rigged repairs, but it's still got the "bio-sensor" which has the mysterious ability to make a mobile suit faster, stronger and more durable when used by a powerful [[PsychicPowers Newtype]] pilot whose emotions are sufficiently focused...and Judau is one of the three strongest Newtypes ever recorded.[[/note]] Also, there's also the part of him being one of the few, if not ''only'' major characters from the earlier U.C. series who actually ''survive'' to old age.
** He shows up in ''CrossboneGundam'' to lend Tobia Arronax a hand during one particularly strange mission (which coincidentally [[spoiler:explains how the Gump got its aforementioned peg leg]]). [[CrazyAwesome Umon]], one of the Crossbone Vanguard pilots meanwhile is mentioned as being a non-Newtype ''One Year War veteran'' who managed to scare the ''[[MobileSuitGundam0083StardustMemory Nightmare of Solomon]].'' While piloting a ''[[MechaMooks Ball]]''.
* ''Manga/VinlandSaga''
** More a case of a Badass Great Uncle than Grandpa but still...Thorkell the Tall. Pure BadAss, despite the goofy grin he's always sporting.
** Askeladd's getting along in years as well, yet he is still stronger and harder than most men half his age.
* Tenchi's grandfather Katsuhito in the ''[[Anime/TenchiMuyo Tenchi]]'' series, [[spoiler: who is later revealed to be Ayeka's half-brother Yosho.]]
** Some exposition may be needed, since there are like 5 different continuities. In the spoiler above is the case in the {{OVA}}s, and his feats include fighting off a brainwashed [[PersonOfMassDestruction Ryoko]] who's under Kagato's control and fighting Kagato himself at the same time...and not even seeming to take the fight all that seriously.
** In the ''Anime/TenchiUniverse'' series, he's still [[spoiler: related to Jurai, but ran away to chill on Earth.]] As an old man, he...does fairly well...against the BigBad [[spoiler: Kagato who is his old friend and has a huge advantage due to a much younger body]], and is introduced into the series by taking out a Galaxy Police Mecha with a [[RockBeatsLaser wooden sword]].
** In ''Anime/TenchiInTokyo'' he's [[spoiler: Guardian of the Earth]], but he was getting Tenchi to take over.
** In ''Magical Girl Pretty Sammy'' he never shows up, but in ''Magical Project S'' he makes a cameo as a sickly old man. Though he still talks like a badass though.
* Hiko Seijiro from ''Manga/RurouniKenshin'', Kenshin's teacher and master of the Hiten Mitsurugi-Ryu sword style, is an example of this trope. He is by ''far'' the most powerful swordsman in the series, capable of matching Kenshin, already established as an impossibly fast and powerful swordsman, in speed even when wearing a 30 kilogram cloak made of metal and possessing strength beyond any other character in the series by a ridiculous degree. In fact, during Kenshin's second training, Kenshin strikes at Hiko with his "entire body and soul" at one point (devoting so much attention that he fails to land properly and passes out), and only manages to graze one of Hiko's bracers.
** WordOfGod says Hiko is so powerful that he could very easily take on virtually ANYONE in the series and completely ''[[CurbStompBattle curb stomp]]'' them.
** Actually, Hiko is just in his 40s so he's still too young for it. (though ''very'' much in his way.) Nenji "Okina" Kashiwazaki, Misao's adoptive grandpa and the ex leader of the Oniwabashu, plays it straight...[[LetsGetDangerous when he gets serious.]]
* In ''Anime/YuGiOh'', the Dark Magician becomes more powerful when aged a thousand years, becoming the Dark Sage.
** Another example: If you read the ''Millennium World'' Manga, Yugi's Grandpa Sugoroku could be classified as this [[spoiler: the combination of James Bond and Indy Jones has him investigating a a pyramid containing the Millennium Puzzle ''in a tuxedo!!!'']]
* ''Manga/OnePiece''
** "Dark King" Rayleigh certainly qualifies. He was the first mate of the former Pirate King, and after about 20 years is able to fight toe to toe with a Marine ''Admiral'', one of the strongest fighters in the World Government (and in the case of this particular Admiral, capable of moving at the speed of light).
*** [[spoiler: He swam across the Calm Belt. A strip of ocean filled with giant sea creatures that even the most hardened Marines & Pirates avoid]]. Why would he do this? Because [[spoiler:His boat sank in the Grand Line, so he had to swim through part of the ''Grand Line'' in order to ''get'' to the Calm Belt. No problem for him. He had a message to deliver.]]
** Vice Admiral Garp, [[spoiler: the grandfather of the protagonist,]] who likes to attack people with a ball on chain the size of a boat, or throw/punch cannonballs at them. Which delivers the cannonballs at far greater velocity than any actual cannon could manage.
** Edward "Whitebeard" Newgate, called "The Strongest Man in the World" [[spoiler: has the power to create earthquakes and massive tidal waves, a particularly devastating ability considering that the entire One Piece world is one big ocean and a collection of islands and archipelagos.]] He controls a massive fleet of pirate ships, and is stated to have the power to destroy the world. Unlike many of the examples on this page, whose fighting abilities seem unaffected by aging in the slightest, the story makes it clear that age has ''already'' more than caught up with Whitebeard. He pulls off some of the most destructive and BadAss stunts seen in ''[[WorldOfBadass One Piece]]'' yet, and he does it all as a [[HandicappedBadass sluggish, half-dead shadow of the man he used to be]].
*** And when he finally does [[spoiler:die... well, to quote the book directly. "Even in death, even with ''half his face gone,'' he would never fall. He will forever be remembered as a monster for the way he destroyed his enemies that day. In this one battle alone he suffered 267 sword wounds, was struck by 152 bullets, and 46 cannon blasts. And yet neither that mighty body nor his pirate's pride suffered even one "coward's wound!" To put it in perspective: When his brain and heart stopped, his body didn't fall over. He had continued to fight for a good ''fifteen minutes'' after HALF OF HIS DAMN HEAD had been blown off by lava. Then he suffered a total of ''four hundred and nineteen'' sword and gunshot wounds, one of which is often an OHK device in manga, and the other of which is an OHK device in the real world. Additionally, 46 cannon blasts, which in the One Piece universe are inexplicably explosive, hit his actual body.]] And this was all in one battle. And over the hundreds of battles he'd fought in over 60 years, ''he had never been hit in the back because he had never turned away from a fight.''
** [[DemBones Brook]], Strawhat Pirates's musician is an 88 year old skeleton who can play any instrument, runs on water and can make a sword attack so fast, that you realize you have been cut [[YouAreAlreadyDead only when he re-sheathes his sword.]]
* Master Yupa from ''Manga/NausicaaOfTheValleyOfTheWind'' is the ultimate Creator/HayaoMiyazaki Badass Grandpa. He wanders the world in peace and solemnity, looking for a solution to the Toxic Jungle, but also has a reputation across the entire world for being a legendary warrior. His finest moment may be ''stopping a sword at its point with his own forearm''--and the force behind the sword in question is the title princess in an UnstoppableRage.
* From ''Manga/{{Berserk}}'', we have Azan. He was once called the Bridge Knight for keeping [[OneManArmy one hundred knights from crossing a bridge]], and while he's no longer in the prime of his life he's still able to match an injured, but still very mean protagonist, Guts in combat.
* ''[[Manga/KenichiTheMightiestDisciple History's Strongest Disciple: Kenichi]]''
** Hayato Furinji might be the baddassest grandpa of them all. His [[RedBaron nickname]] translates to "The Man Without Enemies", because nobody in the entire world qualifies. He's only ever faced ''one'' opponent in his past that gave him trouble in a fight (it still ended in a draw). Unfortunately, it's implied that his opponent was [[spoiler: Pencak Silat Master Silcardo Jenazad of YAMI]]. Another nickname (or perhaps a different translation of the same nickname) is "The Invincible Superman."
** To get an idea at just what we're dealing with here, [[http://www.mangareader.net/337-23736-4/historys-strongest-disciple-kenichi/chapter-230.html this]] is what Hayato considers [[IAmNotLeftHanded holding back.]]
** For further reference, he's currently operating at ''[[http://www.onemanga.com/Historys_Strongest_Disciple_Kenichi/230/09/ 0.0002 percent]]'' of his full power.
*** Well hold on. That wasn't Furunji. That was [[PaperThinDisguise mysterious 20 year-old Garyuu-X]]!
** Hayato once decided to take on an American Army base; when Kenichi expressed concern everyone reassured him that the Elder had too much control to kill anyone.
** Danki Kugatchi, right down to being the tiny bald wrinkled doddering old man. He then proceeds to tear a sword apart with a stick. Badass? I think so.
* ''Manga/DeathNote''
** Watari. Not only is he able to put up with L (a fairly awesome feat by anyone's standards), he's also able to work round-the-clock with him and in the anime version, he shoots [[spoiler: Higuchi]] from a helicopter at least 10 metres away.
** Although he may not be quite on the level of Watari, there's also Light's father, Yagami Soichiro. Often cited as being the only truly righteous character in the BlackAndGreyMorality of the series, he pulls off various feats of badassery in the name of his idea of justice.
*** Just to give you an idea, he rammed a van into a TV station in order to shut down the pro-Kira broadcast. And in the manga and anime, this was after suffering a ''heart attack''.
* In ''TwentiethCenturyBoys'', a couple time skips causes the original main cast to become this. "When a man is singing, you DON'T SHOOT HIM!"
* ''Anime/ShinMazinger'': Juzo. Kabuto.
* Yagyu Retsudo from ''Manga/LoneWolfAndCub''. Despite his old age he virtually controls the nation and is equal in combat with the main character (who is awlays portayed as the most skilled swordman).
* Shiryu's master Dohko from ''Manga/SaintSeiya''. He is a subversion, though, since [[spoiler: thanks to his powers, his old appearance is [[SleepModeSize just an illusion]] and he hasn't really aged ''at all'' in 200 years]].
* Balgus from ''Anime/VisionOfEscaflowne'' definitely counts for ''chopping off the arm of a mecha with a giant sword, on foot''. The only reason he lost was because he was fighting ''giant robots. On foot.'' ''[[EscortMission While protecting someone.]]'' He would've been fine if he'd been alone.
* Bookman from ''Manga/DGrayMan''. Just try to call him "Old Panda" and you'll see.
* Tokaki and his wife Subaru from ''Manga/FushigiYuugi'' are [[BattleCouple Badass Grandparents]], fighting demons and the Seiryuu Seishi Miboshi at over 100. Justified as both of them are Byakko Seishi. Tatara, their fellow Seishi, is a subversion of this trope, seeing as Subaru cast a spell on him to make him look, feel and fight like he's younger.
* While not actually related to anyone, and a DirtyOldMan to the core, Happosai of ''Manga/RanmaOneHalf'' is also a legitimately dangerous old man who, when he puts his mind to it, can be the most powerful OldMaster in the series. Though one of two MiniatureSeniorCitizens, he has once stopped a bomb the size of a small house with just his finger, sent a giant yeti-ox-crane-eel mishmash rocketing skyward with only his pipe, knocked said abomination against nature out with a single one of his homemade bombs, can use his BattleAura with such proficiency he can grow into a kaiju-sized giant version of himself, and can defeat any combination of the teenaged cast with no difficulties whatsoever.
* ''Manga/HunterXHunter''
** [[OldMaster President Netero]].
** And Killua's grandfather.
* Aniya-sensei from ''Manga/KarateShoukoushiKohinataMinoru''. He's over 80 but is extremely muscular and very skilled at karate.
* Fu in ''Manga/FullmetalAlchemist'' is a badass grandpa ninja. [[spoiler:Or at least he was until he got killed by the series other badass grandpa, King Bradley.]]
* ''{{Cyborg Grandpa-G}}''. ExactlyWhatItSaysOnTheTin.
* ''Manga/{{Toriko}}'' has '''THREE''' Badass Grandparents. There's "Knocking Master" Jirou [[spoiler: who can ressurrect the recently deceased through acupuncture among other thingsd]], his cook, Setsuna the Gourmet Living National Treasure [[spoiler: who can easily break the BigBad's [[TheDragon Dragon]]'s weaponry through sheer force of will]], and finally there's Ichiryuu, president of IGO who recently [[spoiler: either stopped or tanked every attack from Toriko and then casually one-shotted him.]]
* Professor Oak is still a pretty good fighter, even though he actually ''is'' a grandfather in ''Manga/PokemonSpecial''. [[NeverMessWithGranny Agatha is the same age]], and is a member of the Elite Four. Wattson and Pryce also probably count. [[NeverMessWithGranny Bertha]] will probably be added to the list once she makes an appearance.
* Xerxes Break of ''Manga/PandoraHearts'' qualifies as well. While his body doesn't show visible sign of aging, he couldn't possibly be any younger than seventy, with eighties or nineties being more likely, and he ''is'' still aging on the inside, often making reference to how surprised he is he hasn't died yet. While Break's main power is technically the Mad Hatter, he's a pretty good badass in his own right- even moreso in the anime, where in episode 24 he takes on dozens if not hundreds of giant supernatural abominations ''with his sword'' while his comrades are struggling to fight them with Chains. Before [[spoiler: finally just calling out the Hatter to cleanse the entire city of a few thousand rogue chains in seconds.]]
* ''Manga/FairyTail''
** Makarov definitely fits. If you hurt his guild members--[[PapaWolf whom he thinks of as his family]]--he will [[UnstoppableRage nuke your ass.]]
** For a villain example, we present you Hades of Grimoire Heart, the former master of Fairy Tail. He seems to be at least a few decades older than Makarov (and Makarov is 88!), but still kicks Makarov's ass without any seemingly problem.
* Walter C. Dornez from ''Manga/{{Hellsing}}'' originally appears as a somewhat [[HandsomeLech pervy]] butler. Next episode, you learn he's a [[RetiredBadass former Master Vampire Hunter]], is highly skilled in creating firearms specialized to destroy vampires, and still has his old touch with his [[RazorFloss monofilament wire skills]].
* ''Manga/AxisPowersHetalia''
** Cuba's "boss" (who could be either of the Castros) in ''Manga/HetaliaBloodbath2010''.
** Germania and Rome are considered to be this in {{Fanon}}.
* Touhou Fuhai in ''Manga/RosarioToVampire'' is a great great grandfather, and he's still more than a match for [[TheDragon Akuha]]. Subverted in that he's at his most {{badass}} when he [[OlderThanTheyLook doesn't look like]] [[{{Bishonen}} a grandpa]].
* Nurarihyon from ''NurarihyonNoMago'', the eponymous character's grandfather. Though the years have not been kind on him, as he is now far from what he was back in his prime, he still manages to curb stomp [[TheHero Rikuo]] in a fight.
* Sir Archer from ''Franchise/LupinTheThird" Pursuit Of Harimao's Treasure, in his youth he was a former soldier and a secret agent for the British Secret Service, in his 80's he can defeat several armed soldiers in combat.
