Guardian of Harmony necklaces

Each Guardian of Harmony gets a special **Power Necklace** (パワーネックレス, ***Power Necklace***?) to wear. These necklaces are pretty special, and even serve as the transformation trinket alongside the Harmony Gem.

## Evolution

* For all stages, in the center of the necklace is a symbol matching the host's Harmony/Cutie Mark.
* Nothing pretty much happens except for getting a Harmony/Cutie Mark for Stage 0.
* For Stage 1, the necklace changes into a choker and the host's eye shine changes to match their symbol and gain their Mark on their cheek.
* For Stage 2, the choker changes to match their magic aura color, the Mark starts going down on their two arms and two legs/four hooves and the cheek Mark changes into a Mark that goes over one of their eyes.
	+ The host will also get an array of spells zapped into their head pretty much, and they're able to know how to use them and for what reason. Each host gets 1 defense spell, one kick spell, one punch spell and 2 attack spells, sometimes more. Some hosts may also have healing spells, or spells that can summon vines and or other appendages out of the ground.
* For Stage 3, the choker changes into a thicker necklace and their hair/mane starts overflowing with sparkles and shine.
	+ Wielders will have stronger magic than Stage 2, but are still able to cast the spells that they could at that level.
	+ The host will be able to conjure up various things pertaining to their Harmony/Cutie Mark even when not transformed.
	+ Ponies will become Alicorns even if they're a Unicorn who didn't even do a unexpected feat of magic one might not hope to achieve.
* For Stage 4, the necklace's color will become gold and the host's magic will be at their full potential permanently, and be especially strong. Gold and even brighter shine will also be incorporated into the host's transformed state.
* Whenever transforming into Stage 5, the necklace will gain jewels on the bottom, and the host will...
	+ Get golden-colored eyes (either one or both)
	+ Have overflowing hair that goes at least down to their ankles (females only)

## Ways to Upgrade

* Stage 0: Discover your talent and realizing your destiny
* Stage 1: Discover a strength that you never knew you had
* Stage 2: Stand up to injustice
* Stage 3: Overcome a great weakness
* Stage 4: Bring others together in unity
* See here for how Stage 5 is earned.

### Exceptions

* Twilight Twinkle is an exception concerning an effect of Stage 3. She became an Alicorn after gaining Stage *2*. Her future self is *another* exception, as the events of "Magical Mystery Cure" occured in her case.
* Katy is the only exception so far concerning Stage 4. She instead earns it when her friends and brother put their trust in her, having understood that sometimes it's best to let things go, which is what causes her outfit to be upgraded.

## Trivia

* Sometimes, the Magic of Friendship will give a Guardian of Harmony a special upgrade, an upgrade that goes beyond the usual stages. The necklace will gain jewels on the bottom for that matter.
* For Pegasi and Earth ponies, they can use active magic only while transformed, meaning they cannot otherwise. Originally, since they have no magic aura, the color of the necklace was instead to change to match their primary coat color anyways, but it was scraped after CheerfulSteekip took a quick look at Alex918's CMM/Harmonic Necklace colors thrice.
	+ It is also confirmed that ponies can possess Elemental types.
* In the prototype Japanese version, the word "necklace" is said in English while "chikara no" is said in Japanese like usual, similar to the incantation "Hana no *powa* (power)" in *Heartcatch Pretty Cure* which also has the last word said in English. The finalized version of both said dub and the official English one instead makes both words spoken in English.
* Due to Porters having electric blue as their main theme color, their necklace colors won't usually match their family's default color.
* If somebody is brainwashed, as shown with Katrina, their necklace will disappear until they are returned to normal. It is unknown exactly where the necklace goes in that state (and the Harmony Gem and weapons), as after Event Horizon is returned to normal, Katrina's Power Necklace, Harmony Gem, and weapons (as she is in her transformed state "under" her corrupted alter-ego) all reappear. However, it is implied that her presumably corrupted Power Necklace "under" her brainwashed self, wherever it goes, is the source of her powers as she is technically still transformed.
* Once a Harmony Gem is created, the two jewelry will be connected, meaning that if one (or both) of them gets destroyed, the host may end up dying instead of heavily sanging.
	+ For example, the Power Necklace and Harmony Gem will both glow dark purple if the host is experiencing negativity.
* Special humans who gain their Harmony Marks before their first transformation (and special ponies who get their Cutie Marks beforehand) will also get Stage 0 Power Necklaces at the same time. There is, however, is one exception due to unusual circumstances:
	+ Miranda's Power Necklace and Harmony Gem were both created by Kyubey after she got ahold of her own Amok since Gabriel had already created his Sentimonster with a Harmony Mark and chose her powers, but did not give her a Guardian of Harmony form since he created her soley to lure the heroes into a trap and was intending to destroy her after she served her purpose. This is the only time Kyubey has ever created a Power Necklace, and she is never seen doing this again.
	+ Tsukiko and Honoko and Mira, however, despite also being reformed villains who were turned into humans, got their necklaces the usual way after earning their Harmony Marks once they had been turned human after having a change of heart during their infiltrations of the heroes in their respective seasons (of respectively, a chibi smiling blue full moon, a chibi smiling hot pink sun, and a gold and red hand mirror) and formed a contract with Kyubey the conventional way.
* Due to their unusual Guardian designs (having merfolk tails), Shawn's, Kylie's, Melissa's, and Chiffon's Harmony Marks go down their arms like usual starting in Stage 2, but also go down their tail as well.
* Originally, **Elemaximum** (エレマックス, *Elemax*?) (which serves as the GoH equivalent of YuYuYu's Mankai) was going to have the same effects as Stage 5, but it was scrapped.
* Twilight Sparkle was already an Alicorn by the time she gained Stage 3.
* A Guardian cannot use another Guardian's Power Necklace and Harmony Gem to transform. If attempted, nothing will happen and the transformation will not work.
