With me now getting into my own created story arcs, expect these to be updated regularly. The only downside is I can no longer use the hidden chapter list to know what chapter I need to upload next.

Art of the Dress
User: Rarita "Rarity" Zeppeli
Ability: Art of the Dress can grow crystal constructs on any molecule. This of course includes anything solid, but also any liquid or even just the air itself, so long as there is some sort of molecule Rarity can grow her crystals without constraint. The crystals grow according to her will, and while some Stand powers hold factors that can halt the initial growth, Rarity can just continue the construct using a secondary growth. Besides factors that can negate the growth, Art of the Dress' only physical weakness is Rarity. This is because Art of the Dress has no physical form. It appears to, with a complete body, but this is merely another construct created so Art of the Dress can directly fight if needed. This also means damaging the body is easier, simply requiring a good deal of force, but doing so is dangerous since Rarity can control the crystals and move them as she needs, as well as track where the individual crystals are. Finally, while non-Stand users can feel the crystals that are created, they cannot see them.

I'll Fly
User: Iro "Rainbow Dash" Dashell
Ability: While I'll Fly does have physical fighting capabilities, its real power is its ability to merge with Rainbow, its wings creating a special "flight field" that extends out ten meters from Rainbow. Within this field is an environment that enables perfect flight from the perspective of an avian predator, such as an eagle or hawk. This includes not just the atmosphere in Rainbow's vicinity, but also gravity, physical health, mental state, even her soul. Abilities that can shrink Rainbow only work if she's standing on solid ground, otherwise they too are negated. Depending on the situation Rainbow's field can even protect those around her, such as acting as a shield against projectiles.

Undead
User: Momonga
Ability: Undead grants the ability to unleash powerful elemental attacks based on eight different natural concepts, earth, air, fire, water, ice, electric, light, and dark. The extent of these spells is determined by the imagination of the user, and Momonga has come up with some creative uses over the years. In fact, Undead's power has proven great enough to summon natural disasters, but doing so has a longer cooldown time as opposed to simply launching a smaller projectile.

Neon Knights
User: Touch Me
Ability: A suit-type Stand that encases Touch Me in a powerful suit of armor. This does more than increase his defense, it also improves his speed, strength, agility, and senses, making him an effective fighter. The suit comes with a sword for combat, and a shield to protect the few weak-points the Stand possesses.

Chemical Romance
User: Herohero
Ability: Chemical Romance reduces Herohero's body down to a spherical core and surrounds him in a gelatinous substance that is amorphous in nature. The slime-like substance is completely indestructible and can take a variety of shapes, including mimicking Herohero's natural appearance. Damaging the core will damage Herohero, but it's at a level of durability just a step above what the human body is normally able to withstand, so doing so isn't easy.

Within Temptation
User: Nigun Grid Luin
Ability: Within Temptation takes the form of a large, hand-held crystal about the size of a baseball. Nigun can use this crystal to conjure a variety of angels of varying types. Months of practice have allowed him to learn all the different varieties he has at his disposal, from simple humanoids to mighty dragon-like angels. It's main weakness is that if someone should take Nigun's Stand from him, since it is a tangible object, he can't access it. Each angel has its own parameters, so the usual stats refer to the Stand itself.

Dawn of Battle
User: Gazef Stronoff
Ability: Dawn of Battle creates a powerful armor and weapon set with five different powers. With it equipped Gazef can regenerate at a level equal to vampires, possesses endless stamina, is immune to ailments such as poisoning or burns, can sense everything around him, and can cut through any defense like paper. Put together it makes Gazef a powerful warrior that could take on even supernatural threats.

Turning Japanese
User: Nishikienrai
Ability: This Stand grants its user abilities akin to a ninja, or at least one featured in Hollywood or other media. He can move at blinding speeds, create effective after-images, launch projectiles with stunning accuracy, and create explosions with a few simple hand-signs. In addition he can summon certain types of animals, and launch chain weapons from his Stand's physical form. It's primary weakness is that it has little defense. It can easily protect Nishikienrai from most normal weapons, but against other power-type Stands it cannot last in a straight fight, which is why it specializes in avoiding getting hit.

Fly on the Wall
User: Brita
Ability: A simple Stand that let's Brita keep track of an enemy while she is engaged in battle. However, she neither has to start the battle nor see the enemy at least once for her Stand to activate. Once someone targets her aggressively, her Stand activates automatically, letting her know she's in danger. It can work on any sort of enemy, whether they have sentience or not.

Dove and Grenade
User: Stella Lux Iumen "Starlight Glimmer" Ryle Vaiself
Ability: Dove and Grenade takes the form of a tattoo on Starlight's back. Its power is to manipulate five elemental concepts in two different ways, either creative or destructive. The five elements she controls are earth, fire, water, wood, and metal. When in creative mode, the elements can heal, protect, and enhance those around her. In destructive mode, it can create powerful attacks that damage or hinder enemies. It's a versatile Stand whose only weakness is the limits of Starlight's imagination.
