Warning: Very long description

Stand name: Holy Diver, Power: D, Speed: B, Range: E, Durability: B, Precision: A, Potential: A. Description: Holy Diver is a stand that allows for the user to send objects they wish into a personal pocket dimension, white space type stuff. There are limits to how it’s used such as a cooldown of 3 minutes before reuse. It’s not reality breaking since the dimension is not infinite, it is only about as large as a small city maybe goes around 40 miles in every direction. The limit to the size of an object that can be transported is somewhere around the size of a monster truck (I haven’t worked out the entire calculations yet). The speed at which an object can be transported is fast but not breakneck speeds, like the speed of swatting your hand like za hando. The range this can be performed is low also similar to za hando, the only difference being that the ability can be “charged” somewhat, the longer the hold the larger the object that can be pulled in. I forgot to mention that this isn’t just a singular object transportation, it’s more of a space meaning multiple objects that fit within the range could be pulled in. If the user does not want a certain object to be pulled then it won’t be as the user wishes. This stand is less about damage and more about storage, it would take a lot of strategy to effectively use this stand for combat. What do you guys think?

Personally, I have a stand idea, too.

Fallout Boy, Power: B, Speed: A, Range: E, Durability, A, Precision: B, Potential: A.
Fallout Boy is a close range power-type stand. And it's simple, really, it rarely uses it's own power, but any stand it clashes with, it learns that opposing stands abilities and keeps it in an 'index' of sorts. However, it can only use these abilities for 15 minutes. It can stack abilities, too, so you can have The World's time stop, and Sticky Fingers' Zipper abilities, but for only 15 minutes. The cooldown for an ability is 5 hours.

So you’d want to actively be looking for stand users if you want to become more powerful. That’s a neat concept.

I also completely forgot to talk about what happens inside the dimension once an object or person is transported. The user can go from reality to dimension as freely as they want with no restrictions on how many times or how fast they enter. Once inside, an object is under the control of the user, able to be picked up and messed around with. They can also interact with objects psycholkinetically, y’know like picking stuff up with your mind, allowing them to easily pick apart objects with ease that normally would have needed a drill to remove the screws. When someone enters the mind they work a bit differently, yes they can be picked up but not as fast or as far as inanimate objects. Instead, the main focus is that they can be disabled/healed. The space needs an average person in order for it to work, meaning if someone were missing a limb or had an extra birth defect the stand would heal and erase respectively. This also applies to the disabling of stands. This change isn’t permanent and is only in effect within the dimension. Which brings me to the final thing, no person or object can escape without the user willing or wanting them to do so.

That sounds like The Hand with extra steps

Basically, but I thought it was decent concept to share.

If you're a JJBA fan then you will.
