->''"[[https://www.youtube.com/watch?v=Ky7VuySERVg Oooooh! It's got chicken legs!]]"''
-->--'''GIR''', ''InvaderZim''

Most [[TankGoodness tanks]] have tracks, some tanks [[WalkingTank have legs]], while others have many, [[SpiderTank many legs]]. These tanks on the other hand, have ''[[CluckingFunny chicken legs]]'', or as they're officially known as ''"reverse-joint"''[[note]]Erroneously, see below[[/note]] or ''[[http://en.wikipedia.org/wiki/Digitigrade digitigrade]]'' legs.

Most of the time a Chicken Walker is a HumongousMecha or MiniMecha but occasionally backwards bending legs pop up on [[ShoutOut cabins]] or other objects as well. While there may be some benefits to a leg shaped like this, it doesn't overcome the fact that these are [[RuleOfFunny inherently funny]] (though you'll find most, if not all military-themed series will be taking them very seriously).

Also note that chickens don't actually have "backwards knees", because the apparent "knee" is actually their ankle and heel joint (and their "ankle" a knuckle), while their ''actual'' knee is much closer to the body (and practically invisible under their coat of feathers). Same goes for horses, and most quadrupeds' hind legs.

Subtrope of WalkingTank; see also SpiderTank.

!!Examples:

[[foldercontrol]]

[[folder: {{Anime}} and {{Manga}}]]
* In ''SuperDimensionFortressMacross'', ''SuperDimensionCenturyOrguss'' and ''SuperDimensionCavalrySouthernCross'', the mech knees bend forward in full-humanoid battroid mode but backward in jet-with-legs GERWALK mode.
** Macross' Zentradi combat pods like Regult and Glaug also fit this trope.
** Earth mechs with Armo-Diver mode and the non-humanoid Invid mecha from GenesisClimberMospeada.
** Most of the above also appear in {{Robotech}}, of course.
* Although rare in Franchise/{{Gundam}}, a few MS have reverse-joint legs when transformed, notably the [[Anime/MobileSuitZetaGundam Gaza-C]], [[Anime/MobileSuitGundamZZ its]] [[Manga/GundamSentinel successors]] and [[Anime/MobileSUitGundamSeedDestiny Destroy Gundam]].
* {{Xabungle}} has quite a few.
* ''TwentiethCenturyBoys'': [[spoiler:the robot designed by the engineer whose daughter the Friend cult kidnapped ended up this way, instead of the blatant ''[[Anime/{{Gigantor}} Tetsujin 28]]'' ripoff they originally wanted.]]
* ''Anime/AuraBattlerDunbine'' has [[http://www.mahq.net/mecha/dunbine/dunbine/botune.htm Botune]]. It seem that the purpose of using this trope is merely to give audiences an impression that it's FragileSpeedster, since most of mech combat is aerial battle.
[[/folder]]

[[folder:Films -- Animation]]
* ''WesternAnimation/{{Nine}}'' has the self-piloted Steel Behemoths -- the Fabrication Machine's primary foot soldiers, who [[ApocalypseHow wiped out humanity]] with their chemical weapons in the film's backstory. None of them are active during the actual events of the movie, though, perhaps due to lack of maintenance -- they're only seen sitting dormant in hangars.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Franchise/StarWars'' has the AT-ST's and their various derivatives/precursors. In fact, they are often called "Chicken Walkers" by fans.
* ''Film/{{RoboCop|1987}}'' has ED-209. Heavily armed, extremely intimidating, can't even walk down a flight of stairs...
** Or down a street. In the second film one gets stuck in a manhole.
[[/folder]]

[[folder:LiveActionTV]]
* From ''Series/KamenRiderFaiz'', the [[http://img.photobucket.com/albums/v629/Kuruni/MS-Story/Vault-Non/sb-913v.jpg Side Basher in Battle Mode]].
* The Blue Midget from ''Series/RedDwarf'' was retconned into one of these so they could do a dance number, originally being a tank-like vehicle.
* ''Series/FallingSkies'': the "meks" of the aliens walk this way, but are weirdly designed.
** Several characters discuss the possibility that the meks were specifically designed to intimidate humans, as the aliens themselves are six-legged. On the other hand, it could be a purely technical decision. It's not practical to build a large robot with more than 2 legs (4 max).
* Tweedledee and Tweedledum, from Andromeda.
[[/folder]]

[[folder: {{Mythology}} and Folklore]]
* Russian Mythology And Tales
** BabaYaga's house moves around on actual giant chicken legs.
[[/folder]]

[[folder: TabletopRPG]]
* ''TabletopGame/{{Warhammer 40000}}'' has the Sentinels and Warhound Titans for the Imperium, the Eldar Warwalker, etc.
** The Tau's battlesuits are actually a {{subver|tedTrope}}sion, in that they are closer in appearance to ''actual'' chicken legs than this trope, what with forward bending knees, high ankles, and several widely spaced, broad toes.
* Roughly half the bipedal [[BattleTech BattleMechs]] are like this, including fan favorites like the Timber Wolf (''the'' signature 'Mech of the franchise and the image used on its Tropes page), Mad Dog, Bushwhacker, and Marauder, the rest using standard humanoid leg structure. [[AllThereInTheManual Acknowledged by supplemental material]] by noting that chicken-walkers may traverse rougher terrain but are typically less speedy than man-walkers.
[[/folder]]

[[folder: VideoGames]]
* The Gnomes in ''VideoGame/WorldOfWarcraft'' have [[HorseOfADifferentColor as their racial ground mount]] the Mechanostrider, a [[NinjaPirateRobotZombie chicken-legged mecha resembling an ostrich or emu]].
* In ''CommandAndConquerTiberianSun'', the GDI trades its tanks for the Titan, a chicken walker with 120mm cannon. The ''Firestorm'' expansion adds the Juggernaut, an artillery variant with triple the firepower that needs to be deployed to fire. They go back to tanks in ''Command & Conquer 3'', but the Steel Talons multiplayer faction keeps the Titan. To drive the point home even more, Juggernauts in CNC 3 occasionally comically peck ''just like chickens''!
** ''VideoGame/CommandAndConquerRedAlert3'' generously donates the Empire of the Rising Sun's Striker-VX, an anti-air missile platform that can [[TransformingMecha transform into an anti-ground missile helicopter]].
* All of the bipedal WalkingTank-type ''Franchise/MetalGear'' models (Metal Gears from non-canon spin-offs notwithstanding) followed this design, as did the bipedal mode of [[VideoGame/MetalGearSolidPeaceWalker the Peace Walker AI Weapon]], though the TX-55 Metal Gear and its two derivatives, Metal Gear D and the undeveloped Metal Gear Gustav, do away with the forward-facing knees in favor of backwards-facing ones. The birdlike look is actually lampshaded in the manual, which claims that the small, unmanned [[DummiedOut Metal Gear Gustavs]] are nicknamed "Ostriches" by troops because of the way they walk.
* The Goliath unit in ''VideoGame/StarCraft''.
* Basically the whole idea of ''VideoGame/FutureCopLAPD''. Well, that and {{Flying Car}}s.
* The Raptor from the second ''VideoGame/GPolice'' game. It had the ability to jump and glide (compared to most of the vehicles being planes, with one example of an armoured car).
* You can find many of this in ''VideoGame/ArmoredCore'' series. Befitting of a bird-inspired design, they're better in the air.
* The first boss from ''Super VideoGame/MeatBoy'' called Lil' Slugger is one armed with saws and a chainsaw.
* Biomechanoids from ''VideoGame/SeriousSam'' series are like that. Coincidentially, the biological parts of these walkers are bird tissues.
** There is a Chicken Walker enemy in Serious Sam II, too which is called Torso Mech - The Nervous Chicken.
* ''Videogame/MechWarrior'', being based off ''Tabletopgame/BattleTech'', gets in on this as well with quite a few reverse-joint 'Mechs. The games give some of them a marked hopping-bobbing gait, which can be a bit tough on targeting at times. Chicken walkers in the games typically move faster, but aren't as good at scaling hills or mountains as man-walkers - ''Mechwarrior Living Legends'' features the Thanatos, a mech with anatomically-correct [[http://i.imgur.com/dFd7fRx.jpg chicken-legs]], which is ''very'' [[LightningBruiser fast for its weight]], but has trouble scaling >30% grade hills.
* In one level of ''{{Futurama}}: [[TheProblemWithLicensedGames The Game]]'', you get to ride in a ''literal'' Chicken Rider.
* A ''literal'' one in ''VideoGame/DonkeyKongCountryReturns'', which serves as the boss of World 7. And yes, it's piloted by a chicken.
* In ''ChromeHounds'', you can build your very own, officially known as reverse-joint chassis. The leg form gives enhanced recoil consumption, making them good for light artillery and sniper mechs.
* The Flapper species in ''VideoGame/{{MULE}}''. No surprise, since they are human-sized birds.
* The Star, Panzerstar and Sturmvogel enemies/boss from ''VideoGame/{{Einhander}}''. Interestingly enough, their names mean "Starling", "Armored Starling" and "Thunderbird" in German, quite meaningful when compared to their bird-like legs.
* In ''Franchise/MassEffect'', a majority of the bipedal aliens you encounter have this leg structure, including turians, salarians, krogan, and quarians. Geth also fit the mecha version of the trope (and in some cases, the HumongousMecha version), as their bipedal forms are based the physiology of the quarians that created them.
* All of the mechs of VideoGame/{{Hawken}} use this configuration.
* ''VideoGame/{{Bioforge}}'': The moonbase security bots.
* The AG-9 Walker from ''VideoGame/{{Walker}}'' uses this configuration. It even has very bird-like "feet".
* Light AFW's from ''RingOfRed''. One model even ''looks'' like a mechanical chicken, with a machine gun for a face.
* The Mech from ''Metal Mech: Man & Machine''.
* ''[[http://www.generation-msx.nl/software/bothtec/eggy/388/ Eggy]]'', an old Japanese computer game, stars a mecha named Ena that walks like this, though it can hover too.
* All of the battlewalkers from ''VideoGame/{{Battlefield}} 2142''.

[[folder: WebComics]]
* ''Webcomic/ProblemSleuth''[='s=] candy mecha is a sentient example. In fact, even after the head is detached so that it can fly off to fight the villain, the legs still are used for various purposes.
[[/folder]]

[[folder: WesternAnimation]]
* ''WesternAnimation/{{Chaotic}}'' featured the Vile Driver card in some episodes.
* ''WesternAnimation/KimPossible'' had giant robotic flamingos.
* ''WesternAnimation/InvaderZim'' once received a [=MegaDoomer=] stealth mech due to a shipping error. GIR was fascinated by its legs (see page quote).
* On ''WesternAnimation/JimmyTwoShoes'', this is one of [[MadScientist Heloise's]] many machines.
[[/folder]]

[[folder: RealLife]]
* Large [[http://en.wikipedia.org/wiki/Theropoda Theropods]] could be considered biological versions of this.
