Below is a list of several ideas I have for an upcoming JoJo's Bizzare Adventure fan narrative. All ideas are tentative and may not appear in the future. Enjoy!

"It Remembers"
Transformational stand that completely changes the physiology of the stand user, giving the user supernatural strength, agility and speed. The form is assumed and maintained by the ingestion of blood."The Forever Story"
Independent Stand
A CD that has a song that causes hallucinations when heard, sending users into a trance-like state. The only way to counter it is to do everything without rhythm."The Proverbial Bellow"
A slightly above average height humanoid stand that is able to graft metal onto any human skin with staples made from the material of the metal used. Is able to superheat and rapidly cool metal in order to shape it."Take My Breath"
Independent Stand
A house that features non-Euclidian geometry. Each of its many rooms have its contents, size and climate determined subconsciously by the stand user or anyone the stand user allows to change the features of said room."Deer Dance"
Stand user is a vampire.
The stand has the appearance of a rusted, riotized M134 Minigun. It features visible and scratched "POLICE" stickers in several locations on the firearm. Its firing rate is much more sluggish than a typical Minigun. When its bullets make impact with an enemy, the blood that squelched out of the victim's body follows the bullet's projectory. Upon returning to the barrel of the stand, the blood of the victim fills a blood reservior that the user may drink from as an energy source."Aerials"
A many-tentacled, Lovecraftian, atomos-like stand that seeks to temporarily consume its enemies. When consumed, the victim finds themselves in a neverending freefall. Primary effects of the stasis include depersonalization and vertigo. The stand's weak point are primordial sacks located beneath the stand's ears. When struck, the victim is vomited back out at a high velocity."Violent Pornography"
Stand user is a metal vocalist.
A megaphone which intensifies the soundwaves of anything spoken into its microphone to a weaponizing degree. Several seconds of exposure ruptures eardrums. After nearly a minute of exposure, the brain begins to destructuralize, turning into a pasty mush that seeps out of the then blown out ears."Beautiful Dude Missile"
Stand user is a vampire.
A bulking, 10 foot tall humanoid stand carrying a barbed-wire coated crucifix the same size as its body. With incredible speed and strength, it is attempts to impale with the spikes of the barbs of its cross. The barbs latch in heavily to the flesh of those impaled, and attempting to remove yourself or the your stand from the spikes rips skin and flesh."Appeal to Reason"
An average-sized humanoid stand that wields a battleaxe. The axe is able to carve straight through humans, but it does not leave any physical damage; all victims are left without even a scar. However, being cleaved through the heart leaves the victim with an overwhelming sense of heartbreak. Victims tend to fall to their knees and begin weeping, unable to explain what is causing them to feel the way they do."Human After All"
Colony Stand
Stand user is a vampire.
Is a series of spiky, papier maché people. Highly contagious, the tiny humans attempt to infect and dig into the skin and muscle in order to create more humans and melt the flesh into the stand user, eventually absorbing the entire victim piece by piece."Lord of the Game"
Beads of sweat that are secreted by the stand user. When transferred to a victim, it causes rapid microseizures in the muscles until those muscles eventually lock. If the stand user is able to cause ingestion of the sweat, it will cause heart palpitations and death."Minor Thing"
A magnifying glass that allows the stand user to see a past reflection of where an object, animal or human being has been. A small hologram-looking scene can be projected by the magnifying glass when exposed to direct light from one side, akin to using a normal one to start a fire."Dead End King"
A black and dark grey humanoid stand which has luminescent eye sockets that emit a flashlight-like effect out to about 50 meters. The longer the user's victim is within the gaze of the stand, the more that strands of matter begin to wrap around their legs. While shiny at first, the color quickly fades as the material alchemically turns into lead. Spikes begin to protrude and stab into the victim's legs, holding them more tightly. The stand has above average speed and a range from its user of about 20 meters. When the victim is crippled, the stand's eyes cease luminescence and reveal that the sockets are pitch black- an endless hole. The mouth of the stand then unhinges from its jaw and begins to vomit a dark, sludgy substance that emits a grey smoke as it projects out into its victim's mouth. The substance is poured into the victim's mouth until rapid onset lead poisoning kills its victim."Comprachicos"
Colony Stand
Human-looking stands whose faces are not visible due to a balaclava-like hood covering their entire heads. Their skin is highly porous and looks to be made of coral. Comprachicos are able to be seen by non-stand users. They are able to synthesize high-potency narcotics from their jacket pockets. Said jacket have an indistinguishable, light whirring noise inside of it. Highly skilled at manipulation, they strive to make a sale beyond anything else. If attempted to be stolen from, they attempt to capture the would-be robber and wrap them in their coats with their incredible strength. After prolonged exposure to their coral-like skin under the jacket, the victims are slowly dissolved. Shortly after full dissolution, a "budding" takes place, and a new Comprachicos is created."The Sharpest Lives"
Stand user is a vampire.
A privileged position inside of a tall clocktower. Gothic in architecture, others in the area report a very calming sensation within the structure. The stand features a tranquilizer-style long rifle with a high magnification scope held inside of a case upholstered to the inside of its bell. Its craft implies a late 19th century build several brass ornate engravings. A small drop of blood can be inserted into the open bolt, which, as the bolt is pushed forward, forms into the dimensions of a .308 Winchester cartridge. Through pneumatic pressure, the "bullet" can be fired subsonically. When a target is pierced with the bullet, they feel an overwhelming sense of clarity. Mental unwellness subsides and the target is flushed of their inhibitions, leading to rash decisions done with a clear mind. The effect of the bullet lasts until sunrise, or around 10 minutes if effected during the day."Nonagon Infinity"
A stand that looks like an articulate garden gnome brandished with a floral pattern on its wooden clothes. When latched onto the head of its user or anyone else the user requests, they are able to quickly run through simulations in their brain to obtain the outcome of a future situation. Such simulations take 9 seconds for all outcomes to fill the brain of the affected. When the affected brain is running through simulations, their sclerae become completely black and what appears to be rapidly moving stars and planetary bodies fly in the in-between."Hot Mulligan"
A group of 8 invisible men and women that seem to inhabit a gas station. Its user is the owner of the establishment, and they speak to him about everything they see inside and outside of the store with perfect recollection. When stared at by one of the invisible people, victims are unable to avert their gaze until the stand looks away."Black Holes"
One head of a siamese twin of a stand, "Black Holes / Solid Ground." This head speaks only truths."Solid Ground"
The other head of a siamese twin of a stand, "Black Holes / Solid Ground." This head speaks only lies."Black Holes / Solid Ground"
A muscular, masculine, average humanoid height close-range stand. It features exemplary strength, able to break the bones of those it strikes with ease. When engaged with a victim, all outside sound entering a 25 meter radius is nullified, creating a deafeningly loud "arena" that it fights in. It has heightened reflexes and dazzling speed. Its user possesses high fighting intelligence, able to predict opponent's movements. Its heads, however, bicker with each other constantly and enjoy taunting their opponents incessantly."An Empty Bliss"
A towering 25-foot stand that has showerheads for arms and a yellow smile balloon for a head. It lumbers apace and spews a slightly acidic numbing solution from its showerheads that causes paralysis with exposure of over 2 minutes. Its dead stand user is kept in its chest in the form of a kennel cage, flies still surrounding the everrotting corpse. Faint wisps of condensation can be seen escaping the corpse's mouth as if it were still drawing breath."The Pulse of the Maggots"
Colony/Independent Stand
A stylized computer mainframe of 90s-era IBM monitors and green and red pulsating computer boxes. When a new host is found for "The Maggots", the monitors perform mitosis to create a new Pulse. The Pulses are able to see a grainy VHS style live feed of the infected individual.The Maggots are goat-horned, extremely tiny beetles that are utilized by the stand user with the intent of burrowing either through the tear duct or through the nostril of a human. When planted in the nasal cavity, after an hour, a wave of negative emotion and rage engulfs the "Maggot"-infected victim. This gives visual information to the user."Til I Collapse"
A drill sergeant that has complete control over its stand user. Its small figure sports a dark green MARPAT outfit (with patterned wide-brimmed hat) and a full face Balaclava. It operates marionette strings in the shadow of the user and any others it is able to string together using the physical force of the currently effected stand user. It is able to independently change stand users at its will when it's able to string them together."Self vs. Self"
A humanoid stand with the appearance of a ghastly fireman, its soot-soaked eye holes dripping neon blue, luminescent tears. It houses incredible strength as it is able to raise entire chunks of solid concrete with ease. Its powers of omnipresent location tracking only activate when its user becomes worried about the well being of another person. Its primary purpose is to save others, and its strength is rarely used in combat due to the timid nature of the palsy-restricted stand user."Joywave"
This stand becomes a manifestation of a better version of the enemy in nearly every way- speed, strength, stamina, intelligence. If successful in combat and the stand is able to land a killing blow, the doppelganger splits from the stand and takes that person's place in society at the whim and beck of the stand user. Each Joywave, however, has an Achilles Heel that can be targeted to cause extreme distress for the stand, causing it to self-harm.
