History Main / RunningOnAllFours

* Daisy Jo from ''Fanfic/AllAmericanGirl'', despite being a pony from Equestria, was reared among humans and prefers to walk bipedally. However, she's faster running in "four wheel drive" (as she calls it), and she resorts to it on certain rare occasions.

* ''Godzilla'', of all characters, in ''Film/GodzillaVsKong''. Despite his proportionately enormous legs and tiny forelimbs, he uses this to ''terrifying'' effect [[spoiler:when he viciously mauls Kong in the manner of an alligator, defeating him]].

* Rocket briefly runs on all fours in ''Film/GuardiansOfTheGalaxy2014'' and does so several times in ''Film/GuardiansOfTheGalaxyVol2'', notably leaping from branch to branch in a forest and landing on all fours when he jumps down. He also comes out of a chair and runs on all fours toward the end of the latter movie and looks perfectly comfortable doing so.

* Some characters in ''WesternAnimation/KungFuPanda'' do this sometimes. For example, Tai Lung normally assumes a two-legged stance during most of the film, like all of the other animals, but in most of his fight scenes he will actually revert to a four-legged stance just like an actual snow leopard would.
* ''WesternAnimation/{{Madagascar}}'':
** {{Lampshaded}} when Marty invites Alex to try it. He later does it again briefly in ''[[WesternAnimation/MadagascarEscape2Africa Escape 2 Africa]]''.

* ''ComicBook/XMen'' foe ComicBook/{{Sabretooth}} is fond of this across continuities.

* In ''Anime/JuniTaisenZodiacWar'', Tiger takes to running on all fours after becoming more animalistic due to heavy drinking.

* In ''LightNovel/JuniTaisenZodiacWar'', Tiger takes to running on all fours after becoming more animalistic due to heavy drinking.

* When babies become mobile for the first time, it involves moving on all fours in the form of crawling.
* Most children have to learn to go up stairs without using their hands. Some still retain this.

* In documented cases of human children being reared by wild animals like wolves, or in one case, gazelles, they are often found being able to run perfectly well on all fours.
* There's a shortage of actual documented cases of humans being literally reared by wild animals... but there's definitely cases of severe neglect by parents and other adults, which is just as bad. It still causes arthritis in the back and wrists by the time you hit your thirties -- we're badly built for it.
* Inverted by some lizards, which walk on four legs but rise up on their hind legs to run.
* Some of the techniques involved in LeParkour.
* Some dinosaurs, like ''Leptoceratops'', some prosauropods and possibly ''Iguanodon''. It was first thought to walk on all fours, then switched to an upright pose, but now some scientists think it could walk either way, though primarily moving on all fours.
* Averted with ''Spinosaurus'': in 2014, new discoveries revealed that its hind limbs were ''far'' shorter than previously thought, and it was assumed that it walked on all fours. However, further biomechanical studies later concluded that its shoulders and wrists were not built for weight bearing (as in with all theropods including birds), which is why it's been returned to a bipedal, though short-legged stance.

* Inverted with kangaroos and wallabies, which usually walk on all fours with help from their tails but hop bipedally to move faster.

* ''Anime/{{Pokemon}}'': Pikachu as well as Typhlosion can function equally well on either four or two legs -- they walk on two legs but run on four.

* ''LightNovel/AnotherNote'''s Beyond Birthday does this, probably to show just ''how'' freaky and maladjusted he is.

* ''LightNovel/AccelWorld'': Mihaya's avatar can change forms into a leopard that runs this way.

* Aisling from ''WesternAnimation/TheSecretOfKells'' sometimes runs the same way in her human form as in her wolf form.
* Mebh from ''WesternAnimation/{{Wolfwalkers}}'' tends to run on all fours at times. Being a WildChild who's also a [[OurWerewolvesAreDifferent Wolfwalker]], this highlights her wild nature.

* Averted in one ''Yakari'' story: Yakari has lost his memory and thinks he's a bear cub. His new mother is teaching how to grow into a proper bear by hunting, fishing and running. However, he quickly discovers he's better at running on two legs.

* The [[DemonicSpiders Lynels]] in ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' are an unusual variant. Being [[OurCentaursAreDifferent centaur]] monsters, they already move around on their four horse-like legs most of the time while attacking with blades and arrows with their humanoid upper arms. But occasionally, they'll charge at Link on all ''six'' limbs to knock him over.

* Monk Mayfair from the ''Franchise/DocSavage'' novels sometimes does this (his arms are so long they almost touch the ground when he is standing up).

* ''Godzilla'', of all characters, in ''Film/GodzillaVsKong''. Despite his proportionately-enormous legs and tiny forelimbs, he uses this to ''terrifying'' effect [[spoiler:when he viciously mauls Kong in the manner of an alligator, defeating him.]]

* Franchise/MarvelCinematicUniverse: Rocket briefly runs on all fours in ''Film/GuardiansOfTheGalaxy'' and does so several times in the sequel, notably leaping from branch to branch in a forest and landing on all fours when he jumps down. He also comes out of a chair and runs on all fours toward the end of the movie and looks perfectly comfortable doing so.

* Apes in the ''Film/{{Planet of the Apes|2001}}'' remake, although mostly bipedal, do this when they are really excited and in a hurry.
* ''Film/{{The Promise|2005}}'' has all of the slaves used as bait in the opening battle move around like this because as slaves they weren't allowed to act like humans. The protagonist Kunlun is easily able to outrun all of his other fellow slaves, but it turns into an [[AvertedTrope aversion]] since he does run faster bipedally -- he's just that good of a runner.
* Samara from ''Film/TheRing'', who crawls up the well and ''out of a TV set.''
* Played for BlackHumor in ''Film/ShallowHal.'' The main characters have a friend with spina bifida, leaving him with limited use of his legs; thus, he gets around on all fours.

* The Lycans of ''Film/{{Underworld}}'', when transformed, run on all fours on ground and ''through trees'' and can easily catch up with horses, either way.
* Film/{{The Wolf Man|1941}}, when transformed, tends to abandon bipedal running when not in the middle of killing someone, which is rare if there's anybody near enough to sink his claws into.

* Some strains of ratfolk from the ''Literature/GarrettPI'' series run by bending forward and bounding on all fours, bouncing their palms off the ground as they go.

* Inverted in ''Literature/TheTerror''; one of the first and creepiest hints that the monster is ''not'' a polar bear is when it starts easily walking around on its hind legs like a human would.

[[folder:Web Comics]]
* Most of the Digitigrade Cyantians of ''Webcomic/TheCyantianChronicles'' are capable of this, though they do so less as adults.
* ''Webcomic/ElGoonishShive'': During the "Painted Black" arc, while Grace is infiltrating Damien's underground lair she encounters Vlad and tries to run away from him. While in her half squirrel/half human form [[http://egscomics.com/?date=2004-01-31 she gets down on all fours like a squirrel to run away from him]].

[[folder:Web Original]]
* Done among several types of ''birds'' in ''WebOriginal/{{Serina}}'' where some lineages of birds, such as the burrowing mole-like bumblets and the deer-like serezelles, evolve to be obligate quadrupeds, becoming flightless and repurposing their wing anatomy back into weight-bearing limbs.

* ''WesternAnimation/{{ThunderCats|1985}}'':

** The Thunderkittens in 2011's ''WesternAnimation/{{ThunderCats|2011}}''.

* Jack from ''VideoGame/PowerStone'' not only runs in all fours: his legs are bent in unnatural angles and his hands don't touch the floor as he never lets go of [[KnifeNut his scimitars]], meaning he's walking on top of ''knives''.

%%Image selected per Image Pickin' thread: https://tvtropes.org/pmwiki/posts.php?discussion=1643091799091485600&page=1

* ''VideoGame/KirbyAndTheForgottenLand'': The fight against Forgo Dedede's second phase has the normally-bipedal penguin King Dedede start running around on all fours like an enraged boar, showing that he's ''[[BrainwashedAndCrazy definitely not himself]]''. [[spoiler: Turns out this was a side-effect of [[BrainwashedAndCrazy constant brainwashing from]] [[EldritchAbomination Fecto Forgo]], whose mental control eventually devolves its victim into a feral beast The same thing happens to [[KingOfBeasts Leongar]], who normally [[FourLegsGoodTwoLegsBetter takes a bipedal stance]] when he's in his right mind, but takes a quadrupedal stance when Forgo tightens its grip on his mind.]]

* ''VideoGame/KirbyAndTheForgottenLand'': The fight against Forgo Dedede's second phase has the normally-bipedal penguin King Dedede start running around on all fours like an enraged boar, showing that he's ''[[BrainwashedAndCrazy definitely not himself]]''.

You know how they say "learn to crawl before you run"? Well, this character has learned to do both ''at once.'' This character may walk or run on two legs but is absurdly fast and nimble when running on all fours. Though running on all fours for humans is still possible, we've evolved to move faster and more efficiently through bipedal motion (our arms would have to be longer to be really good at it).

* Timber Wolf from ''WesternAnimation/LegionOfSuperHeroes'' does this a few times

* ComicBook/SquirrelGirl from ''WesternAnimation/UltimateSpiderMan'' usually runs on four legs, with a characteristic squirrel-like gait.

----

* ''Manga/{{Naruto}}'':
** The eponymous hero does this from time to time, especially in the earlier part of the series, when he was ''less'' aware of the [[SealedEvilInACan 9-Tailed Fox sealed inside him]]. ''None'' of the other characters with Tailed Beasts sealed inside them exhibit this behavior.
** Kiba does this as well. He's a normal boy who was raised in a family who works with dogs.

* Berserk units in ''Anime/NeonGenesisEvangelion'' and ''Anime/RebuildOfEvangelion'' run this way.
* Yamcha does this in ''Anime/DragonBallZ'' after he fails to catch King Kai's Monkey while running on two legs, as part of King Kai's training. He promptly catches him this way.
** Goku as a kid occasionally ran on all fours, usually when he's after food.
* Merle in ''Anime/TheVisionOfEscaflowne'' does this. Justified, as she is a CatGirl.
* An early minor villain in ''Manga/OPartsHunter'' does this due to an absurdly acute fear of heights.
* ''Anime/{{Pokemon}}'': Pikachu as well as Typhlosion can function equally well on either four or two legs - they walk on two legs but run on four.
* Mikoto of ''Anime/MyHime'' does this on occasion, referencing her semi-feral upbringing and how she was largely raised by cats.

* PlayedForLaughs in ''Manga/AttackOnTitan''. Pieck startles Galliard by walking around on all fours with her hair in her face, causing her to look like a StringyHairedGhostGirl. He nearly falls down the stairs in shock, and yells at her to walk like a normal person. She counters that it feels easier to walk that walk that way, after spending two months [[spoiler: in her four-legged Titan form]].
* In ''Manga/ShamanKing'', Joco's integration with Mic gives him tiger abilities that enables him to run with immersive speed running like a tiger on all fours.

[[folder:Asian Animation]]
* In ''Animation/BoonieBears'', the eponymous bears are usually seen walking on two legs but will sometimes run on all fours as a FurryReminder.
* ''Animation/HappyHeroes'': In Season 8 episode 22, Big M. sics a hungry Little M. on Happy S. in his cracker form. Little M. runs on all fours as he chases Happy S. around trying to eat him.
* Wolffy from ''Animation/PleasantGoatAndBigBigWolf'' has been seen running on all fours a few times. For example, in the second movie, Wolffy runs on all fours to escape from some spotlights at Lord Japper's amusement park.
[[/folder]]

* Like his film counterpart, Anguirus [[spoiler: (at least in his true form)]] in ''Fanfic/TheBridge'' is a rarity amongst the mostly bipedal {{kaiju}} in that he runs on all fours; only rearing up on his hindlegs to walk and fight
* Daisy Jo from ''Fanfic/AllAmericanGirl'', despite being a pony from Equestria, was raised among humans and prefers to walk bipedally. However, she's faster running in "four wheel drive" (as she calls it), and she resorts to it on certain rare occasions.

* The MS Paint Fan Adventure ''Water Works'' has [[spoiler: Slick do this with his arm and leg blades. He explains it's faster than walking, but considered rude as "you damage people's floors".]]

* {{Lampshaded}} in ''WesternAnimation/{{Madagascar}}'' when Marty invites Alex to try it. He later does it again briefly in ''[[WesternAnimation/MadagascarEscape2Africa Escape 2 Africa]]''.
* Just like with Alex in [[WesternAnimation/{{Madagascar}} the main movies]], Classified from ''WesternAnimation/PenguinsOfMadagascar'' drops to all fours briefly when he has to run fast.

** In [[WesternAnimation/MyLittlePonyEquestriaGirls1 the first movie]], Twilight Sparkle is seen running on all fours after being transformed into a human, before noticing that she is not supposed to run that way.

* '''VERY''' oddly enough, ''ComicBook/{{Darkseid}}'' does this at one point in ''WesternAnimation/JusticeLeagueWar'', chasing after the Flash in this manner after [[EyeScream having both of his eyes stabbed out]] by the Justice League to stop him from using his Omega Beams.

* ''Film/ThePromise2005'' has all of the slaves used as bait in the opening battle move around like this because as slaves they weren't allowed to act like humans. The protagonist Kunlun is easily able to outrun all of his other fellow slaves, but it turns into an [[AvertedTrope aversion]] since he does run faster bipedally-- he's just that good of a runner.

* Film/{{The Wolf Man|1941}}, when transformed, tends to abandon bipedal running when not in the middle of killing someone, which is rare if there's anybody near enough to sink his claws into.

He also comes out of a chair and runs on all fours toward the end of the movie and looks perfectly comfortable doing so.
%%* Some Decepticons from ''Film/TransformersDarkOfTheMoon''.
* Apes in the ''Film/PlanetOfTheApes2001'' remake, although mostly bipedal, did this when they were really excited and in a hurry.
* Pictured above, Sabretooth from ''Film/XMenOriginsWolverine''.
* The hybrid ''Indoraptor'' from ''Film/JurassicWorldFallenKingdom'' is based on a theropod dinosaur (which are always bipedal), yet it occasionally is seen walking and running on all fours.
* Quadrupedal movement is commonly used in ''Film/BangkokKnockout'' for the freerunning segments, and one of the villains uses it for his fighting style, rapidly scrambling across the floor on all-fours.

* Some strains of ratfolk from the ''Literature/GarrettPI'' series run by bending forward and bounding on all fours, bouncing their palms off the ground as they go.
* Some goblins are said to do this in ''Literature/TheHobbit''. Justified because goblins have longer arms in comparison to their bodies than humans/elves/dwarves/hobbits, and sometimes the bigger ones ''need'' to do this in order to quickly move through tunnels with low ceilings, as their race is subterranean by inclination.
** Also Gollum at times, at least in ''Literature/TheLordOfTheRings''.
* The Woggle-Bug in ''Literature/TheMarvelousLandOfOz'' would walk on two legs, as he felt it was more civilized, but would revert to four legs when he was scared and needed to run faster.

* In ''Literature/{{Dinoverse}}'', Candayce is put into the body of a Leptoceratops, a more lightly built relative of Triceratops. Leptos actually run faster on two legs, but otherwise are more stable when moving on all fours. Initially Candayce refuses to ever walk like that, because on some level it's accepting that she's an animal.

* ''LightNovel/AnotherNote'''s Beyond Birthday does this, probably to show just ''how'' freaky and maladjusted he is.
* Inverted in ''Literature/TheTerror''; one of the first and creepiest hints that the monster is ''not'' a polar bear is when it starts easily walking around on it’s hind legs like a human would.

* The heroes of ''Series/HyakujuuSentaiGaoranger'' run on all fours when chasing an enemy. Also used in the adaptation ''Series/PowerRangersWildForce'', yet downplayed because all of them got Cool Bikes (as opposed to Gaoranger where only the SixthRanger had a bike).

* ''TabletopGame/DungeonsAndDragonsThirdEdition'': From the 3.5[[superscript:th]] edition ''Monster Manual IV'', the varags are feral goblinoids who move and run on all fours. Thus, they are twice as fast as most similar-sized humanoids.

* In ''VideoGame/{{Lugaru}}'', the PlayerCharacter can do this. {{Justified|Trope}}, since he is a rabbit, although normally bipedal.
* The Stranger from ''VideoGame/OddworldStrangersWrath'' starts loping if he runs for long enough. It's actually rather impressive considering the fact that [[spoiler:Stranger's true form is that of a centaur-like creature.]]
* The animal dash ability in ''VideoGame/{{Tomba}}'' allows the titular character to do this.
* The protagonist of ''VideoGame/PrehistorikMan'' runs on all fours.
* In ''VideoGame/KingdomHeartsII'', protagonist Sora does this in [[SuperPoweredEvilSide Anti-Form]].
* The [[OurWerewolvesAreDifferent Worgen]] in ''VideoGame/WorldOfWarcraft'' usually walk around on two legs, but go to all fours when they need to move fast. The playable Worgen have this ability, called "Running Wild", instead of a racial mount.
* A few enemies and bosses from ''VideoGame/DarkSoulsIII'' pull this off, likely as a ShoutOut to [[Manga/{{Berserk}} Guts wearing the Berserker Armor]]. These include the Outrider Knight enemies (and by extension the boss Vordt of the Boreal Valley) as well as [[spoiler: Slave Knight Gael]], the final boss of the last DLC.
* The Fast Zombies from ''VideoGame/HalfLife2'', which have long fingers to seemingly support this.

* ''Franchise/{{Pokemon}}'': Pikachu can function equally well on either four or two legs -- when they're in 3D, they're shown to run on four and walk on two.

* In ''VideoGame/SamuraiShodown'', "Cat Girl" Cham-Cham runs on all fours. She's not actually a catgirl though. She can run faster than the other characters.

* In ''VideoGame/GuildWars2'', the catlike Charr move like this when out of combat.

* In ''Videogame/StreetFighterV'', when Necalli activates his [[SuperMode V-Trigger]], he'll start walking on all fours, befitting his savage nature.
* ''Videogame/MegaManX6'': Blizzard Wolfang normally stands on 2 legs but dashes around on all fours.
* The [[DemonicSpiders Lynels]] in ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' are an unusual variant. Being [[OurCentaursAreDifferent centaur]] monsters, they already move around on their four horse-like legs most of the time while attacking with blades and arrows with their humanoid upper arms. But occasionally, they'll charge at Link on all ''six'' limbs to knock him over.
* ''VideoGame/Persona5Strikers'': During the second phase of Alice's boss fight, she runs on all four limbs like a rabbit, making her faster and harder to dodge.
* Jack from ''VideoGame/PowerStone'' not only runs in all fours: his legs are bent in unnatural angles and his hands don't touch the floor as he never lets go of [[KnifeNut his scimitars]], meaning he's walking on top of ''knives''.
* Ms. Fortune from ''VideoGame/{{SkullGirls}}'' uses this as her forward dash attack.
* In ''VideoGame/SocksTheCatRocksTheHill'', Socks runs faster when he goes on all fours.

* The mudmen zombies in ''VideoGame/Left4Dead2'' stand upright, but will run on all fours if they're attacking the survivors. They don't move any faster than their two legged counterparts, but they gain the advantage of being harder to shoot at since their bodies are lower to the ground and they can also nearly hide underwater when they run through it.
* ''VideoGame/SuperSmashBrosUltimate'': In his [[VideoGame/DonkeyKongCountry home series]], King K. Rool stands upright at all times. He does the same when translated to ''Smash'', except for his running animation, where he moves like a real crocodile.

* Most of the Digitigrade Cyantians of ''Webcomic/TheCyantianChronicles'' are capable of this, though they do so less as adults.
* Webcomic/SlightlyDamned:
** The Jakkai do this when they run but are typically bipedal when just walking or standing.
** [[spoiler:Iratu]] almost exclusively walked like this as a child, the digitigrade legs on both him and the jakkai probably help.
** When [[spoiler:Buwaro]] enters his [[HulkingOut berserk]] [[SuperpoweredEvilSide form]] he runs quadrupedally because his torso and limbs elongate and after drinking the [[spoiler:Rainbow Reverie]] he is [[SuperSpeed fast enough to catch up with a horse drawn wagon]] while running this way.
* Characters in ''Webcomic/VapnthjofrSaga'' frequently drop to all fours [[https://vapnthjofr-saga.com/comic/vapnthjofr-saga-page-188/ when running]].
* The anthro animals in ''Webcomic/KevinAndKell'' typically walk upright, but there are exceptions, such as those living in the Wild or when someone's in a major hurry. A memorable "all fours is faster" [[https://www.kevinandkell.com/2016/kk1210.html comes when Leona]] (a lioness) is chasing a van holding a kidnapped Carl. She even has a passenger (Miranda, a rabbit) clinging to her back and neck.

* Rigby from ''WesternAnimation/RegularShow'' when he needs to move quickly.
* Zeke the Big Bad Wolf from the ''WesternAnimation/SillySymphonies'' cartoon, ''WesternAnimation/TheThreeLittlePigs'' is normally a [[FourLegsGoodTwoLegsBetter bipedal]] [[HalfDressedCartoonAnimal half-dressed]] FunnyAnimal, but at the end of the cartoon, he becomes completely naked, assumes a four-legged stance, and runs away.

* ''WesternAnimation/ThunderCats1985'':
** Lion-O drops to all fours in order to outrun a lava flow on a hillside and catch up to the Thunder Tank.
** Snarf also tends to switch between being bipedal and quadrupedal with little or no reasoning other than what he feels like; his nephew Snarfer distinctly prefers bipedal locomotion.
** The Thunderkittens in ''WesternAnimation/ThunderCats2011''.
* Fifi [=LaFume=] from ''WesternAnimation/TinyToonAdventures'' sometimes does this.

* Pinky the tall mouse from ''WesternAnimation/PinkyAndTheBrain'' would run in his hamster wheel like this.
* ''Franchise/MyLittlePony'':
** Spike from both the original ''WesternAnimation/MyLittlePonyAndFriends'' and ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' is occasionally seen doing this.
** Discord is usually bipedal, but he drops to a quadrupedal stance for a boost of speed in "[[Recap/MyLittlePonyFriendshipIsMagicS6E26ToWhereAndBackAgainPart2 To Where and Back Again – Part 2]]", as he can't use his usual magic to move around.

* Beast Boy from ''WesternAnimation/TeenTitansGo'' occasionally does this.

* In the first episode of ''WesternAnimation/TeachersPet'' when Spot the dog first puts on his human disguise and enters the school everyone points and says "Who's that kid running on all fours?", they lead the viewer to think it's Spot but it's actually resident weird kid Ian Waseluski.

* Catra from ''WesternAnimation/SheRaAndThePrincessesOfPower'' has gotten down on all fours to run sometimes, especially when she's in danger. It makes sense since she's a cat girl.

* In documented cases of human children being raised by wild animals like wolves, or in one case, gazelles, they are often found being able to run perfectly well on all fours.
* There's a shortage of actual documented cases of humans being literally raised by wild animals... but there's definitely cases of severe neglect by parents and other adults, which is just as bad. It still causes arthritis in the back and wrists by the time you hit your thirties -- we're badly built for it.

She counters that it feels easier to walk that walk that way, after spending two months [[spoiler: in her four-legged Titan form]].

* ''Webcomic/ElGoonishShive''. During the "Painted Black" arc, while Grace is infiltrating Damien's underground lair she encounters Vlad and tries to run away from him.
