History Main / EmeraldPower

* 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]].

** ''TheLegendOfZelda'': Link, The Triforce of Courage, and the Goddess of Courage Farore are represented by Green

* The tip of the [[Series/DoctorWho sonic screwdriver]] glows green.

* '' Film/HeavyMetal''. The ArcVillain of the various episodes of the movie is the Loc-Nar, AKA the "Sum of All Evils". It gives off a green glow whenever it exerts its power.

* ''SuperMarioBros'' as the Green Mushroom
* Tiberium from the ''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 ''SonicTheHedgehog'' are a bit of a subversion as they're not ''all'' green. They're still the strongest phlebotium in the universe.
** Also, the Master Emerald.

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. Sometime, a ''character'' himself is this if his green skin is a distinctive feature.

Not to be confused with GreenRocks, which as nothing to do with...[[{{Irony}} green rocks.]] Related to SicklyGreenGlow (sub-trope, for when the green thing is evil). SisterTrope to SupernaturalIsPurple.
