Sailor Moon gives the original line-up of Sailor Scouts power over a different element. Sailor Mars is Fire, Mercury takes Water, Jupiter swaps Earth for Lightning note In the manga she had Earth as well and this carries over to Pretty Guardian Sailor Moon and Moon of course takes Air. When Sailor Venus joins them she of course has Light.
The Witches 5 from the first anime's S season have this too. Eudial is Fire, Tellu is Earth, Viluy is Water/Ice and Cyprine is Air. Mimete appears to be the odd one out as her attacks involve shooting stars from her guns.
God's Right Seat from A Certain Magical Index follows this trope with Vento of the Front, Terra of the Left, Acqua of the Back, and Fiamma of the Right.
The four generals in Tengen Toppa Gurren Lagann are not only generals of their respective element, but half of their Theme Naming comes from a traditional Elemental Embodyment. There's Thymilph for fire, Adiane for water, Guame for earth, and Cytomander for air. Oddly, the embodiments Thymilph and Cytomander are named after are swapped in regards to their elements.
The Batman and the Outsiders villain team The Masters of Disaster featured characters with water, earth, air, heat and cold powers.
Johnny: Fire. He has the power to self-ignite, so it's fairly obvious.
Sue: Air. She has the power to become invisible and can make the air exert force, like the wind.
W.I.T.C.H. has the four elements for Irma(water), Taranee(fire), Cornelia(earth) and Hay Lin(wind), plus Energy for Will.
Yu-Gi-Oh! GSTART has the Sykonetyks, a strange street gang who dress in thematic jumpsuits and wield Decks of their corresponding Attribute. Their nicknames are even the Greek-derived prefixes of their elements: Hydro, Aero, Geo, Pyro.
The Craft Nancy represents Fire - she is the most passionate and dangerous of the girls, Sarah represents Earth - the most grounded and mature of them, Bonnie represents Air - she is the most in tune with her surroundings , and Rochelle Represents Water - she is a swimmer.
The Ghost Rider movie used this to justify villain Blackheart's Quirky Miniboss Squad's theming of Air, Water, and Earth — with the Rider himself handling Fire.
Sherlock Holmes the 4 murders in the movie can be categorized by this, the midget who worked for Blackwood was buried alive in his coffin, Sir Thomas drowned in his own bathtub, the American ambassador was immolated, and finally Blackwood plans to kill everyone in the parliament by releasing poison in the air.
In Sucker Punch each of Baby Doll's fantasies when she's dancing is based around a different element. The first one in the temple is water/ice. The World War I stage is Earth. The medieval castle stage is Fire. And the final monorail stage is Air.
Angels and Demons uses the theme of the four elements in the murders of four Catholic Cardinals and in the clues to the location of the Illuminati's meeting place.
In Shannon Hale's Books Of Bayern, the four female leads could qualify. Isi is a wind ie. air speaker, Enna is a fire speaker, Dasha is a water speaker and Rin is a tree speaker, which could be reinturperated as earth
J. K. Rowling has stated that the four Hogwarts houses are based off the four elements. Gryffindor is fire, Hufflepuff is earth, Ravenclaw is air, and Slytherin is water.
This can be subtly seen in some of the Houses' more prominent members: Slytherin is headed by Snape, a Potions professor who spends most of his time brewing liquid concoctions; Hufflepuff is headed by Sprout, an Herbology professor who spends most of her time potting plants in her greenhouse; Ravenclaw is headed by Flitwick, a Charms professor who is first seen teaching the students how to magically levitate feathers; the most prominent (adult) Gryffindor in the series is Hagrid, who is infamous for his obsession with dragons, and is most often seen in a cabin with a roaring fireplace.
According to Word Of God, the Triwizard Tournament was originally going to have four tasks with each one based on a classical element. However, Rowling had difficulty coming up with tasks for all of them. In the end, the First Task combines air and fire while the Second Task is water and the Third Task is earth.
The Secrets of the Immortal Nicholas Flamel has the Four Swords of Power. Clarent is the sword of Fire, Excalibur of Ice/Water, Durendal as Earth and Joyeuse as Air. The twins also intend to learn each of the four Elemental magics though only Sophie ends up learning them all and Josh only learns Fire, Water and Air.
Super Sentai and Power Rangers often use this setup with their Five Man Bands, though with a fifth member it's a little loose with who the resident "Earth" Ranger is: the combination of elements is usually Fire/Water/Air/Earth/Wood (Kakuranger, Shinkenger/Samurai) or Fire/Water/Air/Wood/Lightning (Gingaman, Magiranger/Mystic Force).
Charmed naturally features this, being a show about witches:
Paige's past life, the Evil Enchantress had the power to conjure the elements. We only see her use Fire and Air, though Paige counters Fire with a blue light possibly representing Water.
Another episode has the sisters using the four elements in a spell to reveal the Eternal Spring. They use dirt from the garden, a fan to create wind, matches to create fire and some water from the tap.
The house itself is built on a spiritual nexus, surrounded by notable elemental points. Oddly this episode used the five Taoist elements instead of the classic ones. Wood was used instead of Earth and the fifth element was Metal.
Battle Realms: The 4 clans can be seen as this, the Dragon clan are water, as they are about meditation and discipline, the Serpent clan are fire, as they freely use gunpowder, and fire, the Wolf clan are earth, as they have a close connection with nature, and use stone and shale as weapons and armor, and the Lotus clan are wind, as their warlocks cast bolts of lightning, and are quick on their feet.
Breath of Fire IV kind of does this. Nina uses wind, Cray uses earth, Scias uses water, and Ursula uses fire. There are, however, two more characters in the party, with Ershin getting the most powerful spells of all elements but too little mana to use them regularly, and Ryu's dragon forms focusing on fire but also having access to wind and earth.
Final Fantasy IV has the Fire, Ice, Lightning trio of Ifrit, Shiva and Ramuh, with the Earth-elemental Titan as slightly stronger, but remakes and the sequel bump Titan down to their level of power and importance for a four-summon ensemble.
Near the beginning of Final Fantasy V, each of the four protagonists is associated with one of the four elemental crystals along with a personality trait associated with said element. Bartz gets wind and quest, Lenna gets water and kindness, Galuf gets earth and hope, and Faris gets fire and courage.
Final Fantasy X actually reduces the traditional series of elements down to just four (there had always been about eight or nine in previous games). Lightning and Ice replace Earth and Air. It also mixes up the strengths/weaknesses a little, with lightning and water being opposed to each other, and the same with fire and ice. There's also the fifth Holy element (Which is good against most things, but especially undead), but it's very rare and hardly ever used.
Kingdom Hearts Coded has Fire, Ice, Wind and Thunder variants for a lot of commands, and each of the four elements go beyond the usual third-tier of spells into advanced commands that each parallel each other.
In both Golden Sun games, each of your party members maps to a specific element, and they characters of each element in the original and the sequel even look alike. But when you get access to the first game's characters in the sequel, you can put together parties of whatever you like.
Continued in Golden Sun: Dark Dawn, where you eventually end up with two party members for each element as in The Lost Age.
Romancing SaGa has 4 Elemental Lords; beings that embody the elements: Pyrix (Fire), Adyllis (Earth), Strom (Water), and Avi (Air). Fighting them is optional; however, failing their Ecology Quests forces you to fight a corrupted yet stronger version of them.
The Elemental Lords/Masou Kishin robots in the Super Robot Wars series uses the classic formation of Earth-Wind-Water-Fire. There's Cybuster (Wind), Granveil (Fire), Goddess (Water) and Zamzeed (Earth). These are the highest order of the elemental robots, there's tons more lesser robots corresponding to those elements too.
The Legendof Zelda Ocarinaof Time has the Spiritual Stones: The Kokiri Emerald, spiriual stone of the Forest (Air/Earth), the Goron Ruby, spiritual stone of Fire, and the Zora Sapphire, spiritual stone of Water.
Total Annihilation: Kingdoms: The four factions and their monarch are base on the four elements they have control over. Elsin of Aramon-earth, Kirenna of Veruna-water, Lokken of Taros-fire, Thirsha of Zhon-air.
Wrath Unleashed: The four factions and their leaders Aenna water demigoddess, Epothos fire demigod, Durlock earth demigod, and Helamis air demigoddess.
Used throughout the Quest for Glory series, especially in the second game, where Shapier is threatened by four Elementals representing the four elements. Four of the five games in the series (discounting III, which was made at the last minute and thus is the Odd Name Out) also represent the four elements, with I representing earth, II fire, IV air and V water. There is a fifth "pizza" element, used mostly as a joke, though the AGD Fan Remake of II includes a Pizza Elemental as a Bonus Boss.
Boktai gives you access to earth, fire, water, and wind type elements each with their own propertiesnote Earth revives plants, fire melts ice and burns wood, water extinguishes flames, and wind smashes rocks. You also get solar as the default attack, lunar which expends no energy but inflicts no damage, and dark which is reserved for the New Game+. It only gets more complicated in the sequels.
In Brave Frontier, four of the six elements (Fire, Water, Earth and Thunder), forms a variant of this ensemble, where they form an elemental wheel.
Played with in 8-bit Theater when the Dark Warriors find the elemental orbs of light and divide them amongst themselves. Two were clear cut (the Earth Orb for the elf and Water Orb for the pirate), but the other two were just given to whoever.
In The Order of the Stick, Vaarsuvius once complained about Redcloak refusing to play by this trope and summoning elementals based on the periodic system instead.
Vaarsuvius: Titanium elementals. Very distasteful. Does he not know the classic elements are classic for a reason?
In the hybrid webcomic/browser game Demon Thesis, the four main characters find themselves gifted with these powers after a mysterious entity from another dimension starts interfering in our world. There is one exception though: Sam's powers are actually over ice rather than water.
Action League Now: The Flesh represents Earth (has strength far surpassing an ordinary Chuck-o-mation character), Thunder Girl represents Air (her super ability is flight), Stinky Diver represents Water (he's a scubadiver, no doubt), and Meltman represents Fire (what else but fire, or Heat, to have givin him his melted form?).
Galaxy Rangers: Zach: Earth (very connected to his family, very literally grounded, augmented strength, Lawful Good leader), Shane: Water (shapeshifter, friends with dolphins, names his horse after a sea god), Niko: Fire (Fiery Redhead, psionic blasts), Doc: Air (Air is the element of ideas, communication, and bullshit - and he's well-stocked on all three)
It may not be intentional but in Code Lyoko the sectors seem to reflect the elements. The desert sector is fire, the ice sector is water, the mountain sector is air and the forest sector is earth. In fact sector 5 could be considered the aether.
Young Justice: T.O. Morrow created his "Reds" to have powers over the four elements: Red Torpedo (water), Red Inferno (fire), Red Tornado (air) and Red Volcano (earth).
Electromagnetism, gravity, and strong and weak nuclear forces are the four fundamental forces in particle physics.
States of matter. Earth, water, air, fire? Solid, liquid, gas, plasma.
(Fire is sometimes plasma, sometimes not. It's complicated. But many people consider it to be plasma because strong fires can be affected by magnetic fields.)
Sources of renewable energy: Geothermal (Earth), Hydroelectric (Water), Wind (Air), and Solar (Fire). Probably the closest thing to Elemental Powers in Real Life.
