[[quoteright:350:[[VideoGame/PokemonRubyAndSapphire http://static.tvtropes.org/pmwiki/pub/images/weathertrio_2538.jpg]]]]

A type of trio. SubTrope of PowerTrio.

Also a form of ElementalRockPaperScissors, in which the three elements of [[DishingOutDirt Earth]], [[MakingASplash Water]] and [[BlowYouAway Air]] are made a [[RuleOfThree trinity]].

Land is usually depicted as steady and stable, Sea as unpredictable, and Sky as free spirited. Land may also involve death because of burials, and sky will often be the "king," especially in works created before human flight, since no matter where you are, you're always under the sky. The "sky is king" motif has become less common since flight became a thing, however.

Sea is usually depicted as the most hostile of the three; considering most of the time humans are at sea, they're on a pretty small (relatively speaking) ship, and at the mercy of the extremely unpredictable sea, which could decide to throw storms, whirlpools, tsunamis and other unpleasant things at you at any moment, this is hardly surprising.

In an ElementalRockPaperScissors setting, expect Sea to overcome Land [[note]]The seas will wear away even the toughest landscapes[[/note]], Land to overpower Sky [[note]]Land blocks the wind and can withstand whatever the sky throws at it[[/note]], and Sky to defeat Sea [[note]]The waters of the sea are easily tossed around by the sky's winds and storms[[/note]].

These are considered to be the three classic Theatres of War, each with its own branch of the military (Army, Navy, and Air Force respectively) specialized to fighting in it.

See also FourElementEnsemble and FireIceLightning, another common elemental trio.

[[folder: Anime & Manga ]]

* The Bigs from ''Anime/TheBigO'' fit the common characterizations of their spheres — [[TheHero Big O (land)]] [[WildCard Big Duo (sky)]] [[BigBad Big Fau (sea)]]
* Magmatron from ''Anime/BeastWarsNeo'' is made of three units: Landsaur, Skysaur and Seasaur.
* In ''Manga/{{Bleach}}'', there's a subtle name theming referred to these three elements in the Shiba siblings: Kaien (Kai = Sea)[[note]] Bonus points for Kaien's Shikai controlling water.[[/note]], Ganju (Gan = Rock, hence earth) and Kukaku (Ku = Sky).
* The Amazon Trio from ''Franchise/SailorMoon'': Tiger's Eye (land), Hawk's Eye (sky) and Fisheye (sea).
* In the ''[[Franchise/DotHack .Hack//]]'' first series, the great heroes of The World MMORPG are Balmung of the Azure Sky and Orca of the Azure Sea. Eventually, Kite joins them, although his title is "Azure Flame" rather than earth.
* In ''Manga/OnePiece'', one can see the three Admiral's elements in such a light: Akainu (MagmaMan) is Land, Aokiji (AnIcePerson) is Sea and Kizaru (HardLight) is Sky. Is also reflected in their fighting styles, with Aokiji freezing the sea to fight and Kizaru attacking from above. Their personalities fit too, Akainu is a hardline enforcer of absolute justice, Kizaru often seems blisfully ignorant of his actions and Aokiji treats most matters with cold disdain and indifference.
* ''DairuggerXV'' there three teams with vehicles which combine into the titular mecha, they are Kurugger (Air), Kairugger (Sea), and Rikurugger (Land).
* The main characters and their Mashin in ''MagicKnightRayearth'': Hikaru/Rayearth (Land), Umi/Selece (Sea), Fuu/Windam (Sky). Note that Hikaru's attacks use fire, but this can be seen as the lava/magma which lies beneath the earth.
* The three forms of ''Manga/GetterRobo'' are [[TheMario sky]], [[FragileSpeedster land]], and [[MightyGlacier sea]]. Especially obvious for the G Getter.
* First half of ''GundamSEEDDestiny'' featured with Earth Alliance's [[TransformingMecha transformable]] [[SuperPrototype Gundam]] [[PowerTrio trio]] : ground combat Gaia (transform into dog-like mode), aquatic combat Abyss (transform into stingray-like mode), and aerial/space combat Chaos (transform into bird-like mode) representing [[CaptainObvious land, sea, and sky respectively]]. The first two even bearing MeaningfulName.
* The 2005 ''Gaiking'' series has Gaiking become Sea to Vulking (Land) and Raiking (Sky). It's rarely obvious due to Gaiking being TheMario and using fire-based powers, but in the fight where the two are captured, the Daiku Maryu drags the other two dragons under the ocean to take advantage of the fact that each of them suffer from CripplingOverspecialization and the Daiku Maryu doesn't. Both the original series and the remake also fit the theme with Gaiking's support machines (Bazolar and Kill Jaguar are Land, Skylar and Stinger are Sky, Nesser and Crab Bunker are Sea.)
* In ''Anime/MagicalGirlLyricalNanohaStrikerS'', Nanoha is a Tactical Instructor for the Air Force, Fate is an Enforcer who is also part of the Dimensional Navy, and Hayate is part of the Ground Forces. However, after the GrandFinale, Hayate eventually joins the Dimensional Navy as well. Chrono, Lindy, Reinforce Zwei, Teana, Shario, Griffith, Lucino, Cinque, Dieci and Wendi are part of the Dimensional Navy. Vita, Signum and Agito are part of the Air Force. Shamal, Zafira, Erio, Caro, Vice, Alto, Genya, Ginga, and Subaru are part of the Ground Forces.

%% The following {{Zero Context Example}}s have been commented out and copied to Discussion. Please don't add them back unless you also add context to show how they fit this trope.
%% * A common referent in CelticMythology.
* The Three Great Beasts, Behemoth (Land), Leviathan (Sea), and Ziz (Sky).
* GreekMythology
** Zeus got sky, Poseidon got the ocean, and Hades drew the short straw for the Underworld. Land was left for humanity.
** Also, there are the primordial gods Gaia (the earth), Oranos (the sky), and Pontus (the sea). Gaia, the first and born out of Chaos, conceived Uranus and Pontus via parthenogenesis, and [[IncestIsRelative then mated with them]]. Most notably, the Titans and Greek pantheon were the byproduct of her union with Oranos. Additionally, Tartarus (the hell-pit) was sometimes perceived as a primordial deity/force of nature.

[[folder: Comic Books ]]

* The Terrible Trio, a group of ''Franchise/{{Batman}}'' villains introduced in the SilverAge, were criminals wearing masks of animals: Fox (Land), Shark (Sea) and Vulture (Sky).
* The big three Marvel (or rather, their predecessor Timely) heroes of World War II: CaptainAmerica is Land, {{Namor}} is Sea, and Human Torch (Jim Hammond, not [[ComicBook/FantasticFour Johnny Storm]]) is Sky.

[[/folder]]

[[folder: Film ]]

* ''Franchise/{{Godzilla}}''
** The [[{{Kaiju}} "Guardian Monsters",]] who come to defend Japan from Godzilla in ''Film/GodzillaMothraKingGhidorahGiantMonstersAllOutAttack''. There's Baragon (Land), Mothra (Sea) and King Ghidorah (Sky).
** The three monsters in ''Film/{{Godzilla 2014}}'' fit this trope. The amphibious Godzilla represents Sea, to the point where his initial BigEntrance involves a GiantWallOfWateryDoom and a FireWaterJuxtaposition in the form of soldiers shooting flares past his drenched hide. The male M.U.T.O. represents Sky, being a GiantFlyer whose {{EMP}} is the one that takes down the most aircraft and whose second major scene sees him directly attacking an airport. The female M.U.T.O. represents Land, being (as far as we know) entirely land-bound and the monster that is seen furthest inland (namely, the Nevada desert).

[[folder: Literature ]]

* In Julian May's continuity of the ''Literature/BlackTrillium'' series, there are three Archwizards: of the land, sea, and sky. Binah, the only non-evil sorceress in the original book, is retconned as the Archmage of the Land.
* Creator/JRRTolkien's ''Literature/TheLordOfTheRings''
** In the end of ''[[TheSilmarillion Quenta Silmarillion]]'', all three of the eponymous Silmarils are distributed equally across the sky (Eärendil's Silmaril), earth (Maedhros'), and sea (Maglor's).
** The Three Rings, which followed an "Air, Water, Fire" motif instead, essentially swapping Earth for Fire. In [[TheHistoryOfMiddleEarth the first draft]], the Ring rhyme goes "Three rings for the Elven-kings of earth, sea and sky".
* In ''Literature/SeptimusHeap'', during the '''Triple Restore''', Septimus, Jenna and Aunt Zelda take the roles of the Air, Water and Land during the spell.
* In ''Literature/HarryPotterAndTheGobletOfFire'', the three tasks of the Triwizard Tournament can be categorized as this: the first task is sky, and involves Harry using his broomstick to win it, the second task is water, where the competitors have to dive under the lake, and the third task is land, and takes place in a labyrinth.

[[folder: Live Action TV ]]

* Very common in ''Franchise/SuperSentai'' and ''Franchise/PowerRangers'' series, such as ''Series/TaiyouSentaiSunVulcan'' (Vul Eagle = air, Vul Shark = sea, Vul Panther = land). The most important position, that of the [[LawOfChromaticSuperiority Red Ranger]], is usually the one with sky.
** ''Series/SeijuuSentaiGingaman''/''Series/PowerRangersLostGalaxy'' has the Steel Starbeast [=GigaRhinos=] / Centaurus Megazord (land), Giant Steel Starbeast [=GigaBitus=] / Zenith Carrierzord (sea), and Steel Starbeast [=GigaPhoenix=] / Stratoforce Megazord (sky).
** The Hayate/Wind Ninja Academy in ''Series/NinpuuSentaiHurricaneger''/''Series/PowerRangersNinjaStorm'' teaches these three disciplines, and the three core Rangers each wield one. Interestingly enough, the Rangers that join the team later use different abilities altogether (the next two, from a rival academy, use Thunder; and the sixth is either Fire or NonElemental depending on which show you're watching). The ''Ninja Storm'' Rangers also have corresponding extreme sport hobbies: Tori surfs, Shane skateboards (and, consequently, spends a lot of time grabbing air), and Dustin's motocross racing has him driving on earthy tracks.
** ''Series/TensouSentaiGoseiger''/''Series/PowerRangersMegaforce'' has a team of ''two'' Rangers of each, except for sea, which only has one (''Goseiger'' explains it as the second sea Ranger being killed off in the backstory; ''Megaforce'' downplays the motif and ignores the imbalance entirely). Gosei Knight/Robo Knight uses all three. There's also one MechaExpansionPack for each category, and the various villain groups qualify as one has a SpaceBase (representing sky), one has an ElaborateUndergroundBase, and the third as an UnderwaterBase.
** ''Series/JukenSentaiGekiranger''/''Series/PowerRangersJungleFury'' actually gives this to the villains rather than the heroes in the three Fist Demons/Overlords; giving you Kata/Carnisoar (Hawk/Air) Rageku/Jellica (Jellyfish/Sea) and Maku/Grizzaka (Bear/Land). The heroes do have their own version, though, as their secondary mentors (and therefore secondary weapons and mecha) are based on the Elephant, Bat, and Shark.

* The heroic trio in the modern version of BattleBeasts is Vorin the ram, Gruntos the walrus, and Merk the falcon.

[[/folder]]

[[folder: Video Games ]]

* Although the three elements are not the main source of their power, in ''Franchise/KingdomHearts'', Sora means 'sky' in Japanese, Riku can be translated into 'land', and 'Kai' in Kairi can be translated into 'ocean'. Sora and Riku pick up some specific wind and earth attacks in ''3D'' - we'll see if Kairi does the same. Also applies in ''VideoGame/KingdomHeartsBirthBySleep'': Ventus, Terra, and Aqua means 'wind', 'earth', and 'water' respectively in Latin. Their ElementalPowers are more emphasised than the other trio (so far). To a lesser extent, Roxas (An anagram of "Sora" with an X added, while also meaning "red" itself, so could be interpreted to be "twilit Sky"), Axel/Lea (Meadow), and a split between Naminé (''nami'' = wave) and Xion (''shio'' = tide).
* ''Franchise/TheLegendOfZelda'':
** The transformations in ''VideoGame/TheLegendOfZeldaMajorasMask''; Deku is air (flower helicopter), Goron is land (stone rolling), Zora is Sea (dolphin swimming).
** In ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]'', the first three {{MacGuffin}}s are collected from the sky spirit Valoo, the earth spirit the Great Deku Tree, and the sea spirit Jabun.
** This extends to the Golden Goddesses themselves. Farore is associated with wind, Naryu is water and while Din is mostly linked to fire, she also formed the terrain of Hyrule itself.
* Three of the Four Guardians of Neo Arcadia in ''VideoGame/MegaManZero'' fit this mold. Each functions as the military general of their own unit: [[BlowYouAway Sage]] [[ShockAndAwe Harpuia]] commands the Rekku Army (the air force), [[AnIcePerson Fairy]] [[MakingASplash Leviathan]] is leader of the Meikai Army (the navy), and [[PlayingWithFire Fighting Fefnir]] controls the Jin'en Army (the army). This is off-set partially by the fourth Guardian ([[NonElemental Hidden Phantom]]) and his Zan'ei Army, which was Neo Arcadia's stealth force and anti-[[LaResistance Resistance]] intelligence unit.
* ''VideoGame/{{Mega Man X}}4'' has three of Repliforce's high ranking members of the Army ([[KingOfBeasts Slash Beast]]), Navy ([[FlyingSeafoodSpecial Jet Stingray]]) and Air Force ([[OminousOwl Storm Owl]]).
* ''VideoGame/PokemonRubyAndSapphire'':
** Groudon (land), Kyogre (sea), and Rayquaza (sky), all of which were based on the aforementioned Three Great Beasts. It has another one in the form of Berries, surprisingly enough. Three especially rare Berries: Liechi, Ganlon, and Salac, are described to [[PowerUpFood contain the power]] of the sea, land, and sky respectively.
** Trubbish/Garbodor, Grimer/Muk, and Koffing/Weezing in terms of pollution.
** [[http://pokemaniacal.blogspot.com/2011/11/deino-zweilous-and-hydreigon.html One fan]] used this trope to describe the three Pokémon he defined as the only truly ChaoticEvil Pokémon: Tyranitar (land), Gyarados (sea) and Hydreigon (sky).
* ''VideoGame/ResidentEvil5'': the Earth, Sea, and Sky Emblems used to open a gate in one level.
* ''VideoGame/MitsumeteKnight R: Daibouken Hen'' has the Slates of Earth, Sea and Sky. Scattered throughout the world, you need to gather them and put them all in a machine inside [[spoiler:the Pyramid]] in order to activate the WarpWhistle system.
* Used in one of the riddles in ''VideoGame/BatmanArkhamCity''. Although the wording suggests the classic military interpretation [[spoiler:the actual answer is a shipping company]].
* In the ''BatenKaitos'' series, the three objects used to seal Malpercio are the Earth Sphere, the Ocean Mirror and the Sword of the Heavens, when the sealing is shown in the 2nd game the line "[[spoiler: Marno Ar HelloInsertNameHere]], accursed one, for the sake of the earth, the sky and the ocean, thy life must end!" is used. Of note is that during the games [[spoiler:until the ending]], the earth "polluted and barren", the ocean is sealed away ("and the Lost Ocean") and the lower part of the sky filled with the poisonous "taintclouds".
* In ''AdvanceWars 2: Black Hole Rising'', the three Green Earth commanders fit: Eagle has stronger air units and is the proud leader of the trio, Jess has strong ground vehicles and tends to be very practical (her resupply power actually makes her pretty handy with air and sea units despite the attack power penalty she suffers with them), and Drake specializes in naval warfare and has very damaging CO powers.
* In ''VideoGame/ClockTower 3'' at one point Alyssa must solve a riddle involving the three rooder's stones of Earth, Sky and Sea. To be specific, she must put them in the right order to free some ghosts.
* The party members of ''VideoGame/ShirenTheWanderer 2'' are Riku, Himakichi, and Asuka. Riku means land, Himakichi is a {{Kappa}}, and Asuka is the name of the ancient capital of Japan associated with flying birds. Oh, and the SixthRanger can [[BreathWeapon breathe]] [[PlayingWithFire fire]], making them a FourElementEnsemble.
* In ''VideoGame/MassEffect3'', the three largest armies can be seen to represent this in their favoured forms of warfare. The Krogans utilise a ground-based Army and Tanks (Land), the Humans use a Space-Navy with many Carriers to quickly deploy Marine forces (Sea), while the Turians provide aerial-support and bombing runs (Sky).
* ''CommandAndConquerRedAlert3'' the 3 factions units emphasize on their armies strength. The Soviets are Land for their tough tanks, the Empire are Sea as their navy's excel in taking on enemy ships, and many of their units are amphibious, and the Allies are Sky because they have the most advanced air units that are fast and hit hard.

[[folder: Western Animation ]]

* ''WesternAnimation/{{Centurions}}'' features Max Ray ("brilliant sea operations commander"), Jake Rockwell ("rugged land operations specialist") and Ace [=McCloud=] ("daring air operations expert").
* ''WesternAnimation/BatmanTheAnimatedSeries'': In the episode "The Terrible Trio" features the eponymous trio from the comics. They all are bored, rich men who inherited family fortunes from oil (land), a shipping magnate (sea), and an aerodynamics firm (air).

* The US Military has the Army, Navy and Air Force.
* The mascots for the Sydney 2000 Olympics were an echidna (Land), Platypus (water, although not sea since platypi are fresh-water animals) and kookaburra (sky).
