Emerald Power



For some reason, the color green is associated with mystical/mysterious powers. In fiction, it's translated by the Artifact of Doom 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.

Not to be confused with Green Rocks, which has nothing to do with...green rocks. Related to Sickly Green Glow (sub-trope, for when the green thing is evil). Sister Trope to Supernatural Is Purple.

General

 * Depicting willpower or courage as a green energy is quite popular:
 * The Green Lantern Corps, obviously. Though as of the 2000s their power has been established as only one of several and not particularly any more special than other colors.
 * Gurren Lagann's mechas and even their pilots turn green when they fight seriously.
 * Same for GaoGaiGar .
 * The Legend of Zelda: Link, The Triforce of Courage, and the Goddess of Courage Farore are represented by Green
 * Radioactive stuff almost always glow green, too.
 * The Simpsons are probably the best example.
 * A bag of money in any media is usually full of green dollars. And money is a power.
 * A witch brew is almost always green - if not the witch herself.
