The Elements of Harmony are six supernatural artifacts which are arguably the most powerful force in Equestria. Though the extent of their power is largely unspecified, it is revealed in Princess Twilight Sparkle - Part 2 that the elements were taken from the Tree of Harmony, however, doing so had the potential to release the Everfree Forest and destroy Equestria. Each artifact represents an element of friendship and can presumably only work if wielded by one who possesses the corresponding trait, and only if all are used together. They have been wielded on rare occasions, particularly during events marked by danger and anarchy as a last resort to restore and enforce the balance of peace and order. However, the effects of their use are generally temporary and non-lethal, usually a form of banishment or imprisonment.
Each Pony's Element[]
The Elements of Harmony are also used to depict all the qualities of a good friend. They are used to beat villians, like Discord , throughout the series. Each pony of The Mane 6 has an element that is unique to their own personality.
Applejack: Honesty
Applejack represents the element of honesty and is commonly refered to as Honest Applejack.
Rainbow Dash: Loyalty
Rainbow Dash represents the element of loyalty for choosing her friends over other ponies.
Pinkie Pie: Laughter
Pinkie Pie's optimism has earned her the element of laughter. She represents the element of laughter for laughing and adding light to seemingly dark situations.
Fluttershy: Kindness
Fluttershy represents the element of kindness for treating others with kindness even if they come off different. She shows this mostly when Princess Celestia tells the Mane Six to teach Discord how to use his magic for good, Fluttershy is the only one to treat him kindly and trust him.
Rarity: Generosity
Rarity's acts of generosity earned her the element of generosity. She demonstrates acts of generosity all throughout the series. In Suited for Sucess she makes each of her friends dresses for the Grand Galloping Gala and redoes them when they are not pleased the first time.
