For some reason, [[color:green:the color green]] is associated with mystical/mysterious powers. In fiction, it's translated by the ArtifactOfDoom or the phlebotium glowing green or being made of emerald. Sometimes, a character ''himself'' is this if his green skin is a distinctive feature.

Possibly due to the fact that normally nothing gives off green or purple light except from artificial sources. Natural incandescent light (such as flame) is red, orange, yellow, white or more rarely blue.

This trope is also why GreenRocks are named so, even though the trope does not require the color.

[[labelnote:Trivia]]In Japanese, both the kanji for "power" (力) and for "green" (緑) can be read the same way (''ryoku''). Thus, "green" is "power".[[/labelnote]]

A SisterTrope to SicklyGreenGlow (sub-trope for when the green thing is evil or scary), SupernaturalIsPurple.



[[folder:Anime and Manga]]
* {{Averted|Trope}} with Jingoro Amayo from ''Manga/{{Basilisk}}'': he is green skinned and possess abilities, but his supernatural power (being a slugman) is probably the lamest in the series.
* ''Anime/CodeGeass'': C.C. is an "immortal witch" with long, green hair.
* ''Manga/DGrayMan'': the Innocences glow green, with Allen's leaking green light in its first, weaker stages.
* ''Anime/DragonBallZ'':
** While a Super Saiyan glow is usually yellow, Broly has a green one. It loses some of the green tint once he gets rid of his father's mind control device, but his signature ki attacks remain bright green.
** Also, both the Earth's God and Dragon Ball final boss, Satan, are Namekians.
* In ''Manga/FairyTail'', Zero, [[spoiler: Brain's SuperpoweredEvilSide,]] uses green colored Dark Magic.
* ''Anime/GaoGaiGar'' G-Stone, which translate ''raw courage'' into energy.
* Sacred Gears in ''LightNovel/HighSchoolDXD'' glow green when activated.
* Anime/TengenToppaGurrenLagann: [[spoiler: Spiral Power. Energy running deep in all sentient lifeforms in some level, brought out by fighting spirit, has the capacity (depending on the user) to grow exponentially, to the point of manipulating and distorting probability and even reality itself, symbolizing progress and evolution. Probably one of the few that can actually have a harming effect, as too much of it can DESTROY reality.]]
* In ''VideoGame/SengokuBasara'', Mitsuhide has a SicklyGreenGlow BattleAura. Considering that [[spoiler:he survived afer being left in a burning temple to die and that he also tries to resurrect his former master Nobunaga with a dark ritual,]] we can see something "mystical" in it.
* In ''Manga/NurseAngelRirikaSOS'', Nurse Angel's power source is the ''Green'' Vaccine, so her attacks often take this color...with the alternative being pink. She does fire off a lot of pink energy too.
* ''Manga/GetterRobo'' has Getter Rays, which represent the power of life and evolution. They are generally animated as green light, either streaming through the cosmos or glowing in a reactor, but the Getter Beam weapon is usually pink for some reason.
* [[PureEnergy Spell-energy]] in ''Anime/LittleWitchAcademia'' is usually green, and so is the "sorcerer's stone" that powers all of their magic.

* The most common and well known form of [[Franchise/{{Superman}} Kryptonite]].
* Gamma radiation, one of the most powerful forms of radiation known to man, is depicted as green in Marvel comics.
* ComicBook/MartianManhunter. A simple glance at him tells you he's just as strong as Superman.
* The original ComicBook/GreenLantern, Alan Scott, could shape and control magic green fire. The book was later rebooted with a sci-fi premise, but still qualified as the Lanterns wielded green alien energy. It was only in the 2000s when Lanterns wielding similar energies of other colors emerged, dropping out of this trope by making green not particularly special.
** Alan Scott's daughter Jade has an internalized version of his powers, plus green skin (and though she has traveled in space, she is not a GreenSkinnedSpaceBabe).
* ComicBook/TheSpectre, God's spirit of vengeance on Earth, wears a green robe and frequently uses green flames with his powers.
* The phrase "Magic is green" is used to refer to Matt Wagner's ''ComicBook/MageTheHeroDiscovered'', as that color is used for the effects of the wizard character.
* The Emerald Empress, a ''ComicBook/LegionOfSuperHeroes'' villainess.
* ComicBook/GreenArrow. Although he is a {{Badass Normal}}, his arrows can be enchanted and green.

* ''WesternAnimation/MonstersVsAliens''' phlebotium, quantonium. It turns Susan into a fifty foot tall woman.

* ''Film/XMenDaysOfFuturePast'' has an eye-only example in [[http://static.tvtropes.org/pmwiki/pub/images/blink_xmen_films_9314.jpg Blink]] (a kinda realistic version of [[http://img3.wikia.nocookie.net/__cb20090310202912/marveldatabase/images/thumb/0/06/Clarice_Ferguson_%28Earth-295%29.png/250px-Clarice_Ferguson_%28Earth-295%29.png the comics counterpart's]] [[MonochromaticEyes fully-green eyes]] - the shade is still unusual, and [[PowerGlows her eyes glow]]).
* In ''WesternAnimation/TheBookOfLife'', [[spoiler:the Medal of Everlasting Life]] glows green.
* In ''Film/WarCraft2016'', the powerful BlackMagic of fel is of vibrant green color, and green-skinned orcs are ones who's been made more powerful by it.

* The Warlock Lord from ''Literature/TheSwordOfShannara'' is a wraith made of eerie green mist.
* Arya from the ''Literature/InheritanceCycle''. Her magic color is green, her eyes are green, (hell, anything associated with her is green) and she is probably one of the most badass characters in the series.
* Akhor/Varien's soulgem in ''Literature/TalesOfKolmar'' is green. As a great silver dragon he's got [[OurDragonsAreDifferent some psychic powers]]. As a [[HumanityEnsues human]] he loses them unless he's holding his soulgem against his forehead. It's also used to [[spoiler: awaken the Lesser Kindred and restore the Lost]] later in the series.
* In ''Literature/TheChroniclesOfThomasCovenant'', power associated with [[GodOfEvil Lord Foul]] and [[ArtifactOfDoom the Illearth Stone]] usually manifests as noxious green light. In the third book while his power is ascendant, Foul ''turns the moon green'', apparently [[ForTheEvulz just because he can]].
* Subversion in ''Literature/TheWonderfulWizardOfOz'' - the green, enchanted glow of the Emerald City is merely tinted glasses and parlor tricks.

* Lorne in ''Series/{{Angel}}''...he was an empath who could tell the future when other characters sang, and he was also a green-skinned demon.
* The Green Ranger of ''Series/MightyMorphinPowerRangers'' is the most powerful one. (Generally doesn't apply to following series, though, where their Green Rangers are just one of the team.)
* The Emerald of the Eclipse in ''{{Series/TinMan}}'', which appears to be a magical or magic-focusing artifact strong enough to stop planetary rotation.

* Many of the magical elements in ''Pinball/MagicGirl'' have either a green color or a green PowerGlow.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Exalted}}'': Green is the color of {{Hell}}, for it's drenched in the light of Ligier. Ligier is a green sun who is also the heart of Malfeas, the King of Yozis and the Demon City itself. Appropriately enough, Hell's chosens are called Green Sun Princes. They have access to OneWingedAngel form in which they turn into green-colored walking nuclear wasteland.

* In ''Theatre/{{Wicked}}'', the green-skinned Elphaba has immense magical power. [[spoiler: And she just happens to be a HalfHumanHybrid, too.]]

[[folder:Video Games]]
* Green mushrooms in the ''Franchise/SuperMarioBros'' series will give you an [[VideoGameLives extra life.]]
** In the first two VideoGame/PaperMario games, the green mushrooms, here called Ultra Shrooms, will instead replenish 50 HP, the most of any item in the games, and the HP {{Cap}} in the first. Meanwhile, the games' 1-Up Mushroom equivalent, the Life Shroom, will only bring you back with 10 HP.
* Tiberium from the ''VideoGame/CommandAndConquer'' series is the most valuable substance in the world (leading to the GDI and Nod fighting over it) and will either kill or mutate anybody who steps in it.
* The Chaos Emeralds from ''Franchise/SonicTheHedgehog'' play with this, as they're not ''all'' green. They're still the strongest phlebotinum in the universe. The Master Emerald, however, ''is'' actually green.
* The soul in ''Franchise/MortalKombat'' is represented as a green energy, which allows character enhance their attacks, conjure spiritual weapons, and empower with the souls of fallen people.
* Life Crystals in ''VideoGame/TheDig''.

** [[TheLifestream Mako energy]], from ''VideoGame/FinalFantasyVII''.
* ''VideoGame/PokemonRubyAndSapphire'': No matter which version you own, the strongest OlympusMons you can catch is Rayquaza, the green dragon. And it's the mascot of the enhanced third version, ''Pokémon Emerald''.
* ''VideoGame/LeagueOfLegends'': [[EldritchAbomination Cho'gath]]'s eyes, the anubite Nasus, the [[GorgeousGorgon snake-like]] Cassiopea, the [[ScaryScarecrows demon-scarecrow]] Fiddlesticks, [[NonHumanUndead Hecarim's]], [[OurLichesAreDifferent Karthus']], [[CannibalismSuperpower Kha'zix's]], [[SiliconBasedLife Malhpite's]], [[MonsterClown Shaco's]], [[TortureTechnician Thresh's]], the CardSharp Twisted Fate, the WildMan Udyr, and [[TimeMaster Zilean's]] eyes all glow green in their artworks. [[{{Understatement}} Riot seems to like this trope]]. And that's not even counting alternate skins!
* In ''VideoGame/BlazBlueContinuumShift'', Hazama's [[SNKBoss Unlimited form]] is surrounded by a green life-stealing aura.
* [[VideoGame/HalfLife The Vortigaunts]] attack with some kind of green lightning. In the multiplayer game ''Half-Life 2: Deathmatch'', it's a OneHitKO.

* In ''Franchise/TheLegendOfZelda'', the magic meter is represented by a green bar. Also, in most games the potion that refills it is coloured green. Also, [[TheHero Link]] is associaated with the green color because of his green clothes, his homeland in most games being a lush forest and Farore, his patron goddess, is also symbolized by green.
* ''VideoGame/DragonAgeInquisition'''s main color is arguably green. There's the magical, glowing mark on the Inquisitor's hand, the Breach in the sky and subsequent rifts, and the powerful [[spoiler: elven]] orb that caused the destruction in the first place. Green seems to be associated with the ancient elves in general, as well as with [[spoiler: Solas, an ancient elf to whom the orb belonged.]]

* ''Webcomic/{{Homestuck}}'': the near-omnipotent First Guardians are powered by the [[color:green:Green Sun]]. Use of their powers is associated with the color green, and occasionally they themselves flash green.

* In ''Webcomic/TheOnlyHalfSaga'', magic used by witches and warlocks glows the classic eerie green, which stands out nicely over the often desaturated browns and grays that fill the comic's desert setting.

[[folder:Western Animation]]
* ''WesternAnimation/DannyPhantom'': The [[PhantomZone Ghost Zone]] is generally green-colored, and the protagonist himself has GreenEyes and [[AlienBlood green blood]] in ghost form and shoots green blast of ectoplasmic energy.
* The Flying Dutchman and his boat in ''WesternAnimation/SpongebobSquarepants''.
* The Omnitrix of ''WesternAnimation/{{Ben 10}}'' gives off a bright green glow whenever it does anything particularly powerful, and Ben's transformations happens in a flash of green light. The Trope only increased as the story goes on: starting with ''WesternAnimation/Ben10AlienForce'', the Omnitrix becomes green itself, the alien forms have green eyes, Ben himself dress in green (and so do his alien forms starting with ''WesternAnimation/Ben10Omniverse'') and it's eventually revealed his favourite color ''is'' green (like we didn't guess). He could generally rival Green Lantern at this point.
** Green is also the favorite color of Azmuth, the supergenius creator of the Omnitrix among other inventions.
* The Power Primate from ''WesternAnimation/SuperRobotMonkeyTeamHyperforceGo'' is normally manifested as green energy -- in more extreme cases, it takes the form of a giant green energy gorilla.
