paramecia rare? it is arguably the most common devil fruit type with only normal zoans being possibly more common (smiles are not devil fruits)

all might tels midoriya that him reporting having quirk while he did not have one before will not be a problem since misreport on ones quirk happens all the time even sometimes with wrong description for years and brings example of a girl (don't remember if he stated it was a girl but the siluete was female) that though that she can shoot water from her fingers and later changed the reported description when she learned that she collects the moisture from around her and concentrates it at her fingers so no they don't have a machine that just tels you the quirk they might have some tests but nothing that is precise

or maybe i should word it like this: with great power come great possibilities and great possibilities give you great choices and said choices result in responsibility

false not even close to full mastery

what about human world and hueco mundo? they all are connected and both have swords although the human ones will most likely always be among the weakest using the hollow resurrection might being curious results

mc's own zanpaktuo comes from the asauchi that was given to him by soul society and all his creations come from his zanpaktuo and while we can argue where its form comes from the zanpaktuo itself without a doubt originates from the creator of zanpaktuos (if directly created or not is arguable) and as a result all his zanpaktuo originate from him

he did not what he manifested was not truly asauchi just a mass of spirit power in the shape of it if he mastered his powers he wouldn't need one but in the whole of bleach he did not reach that level

police academy Red cloystters ?

they did not master hollowfication they reached the first of four steps and did not try more its like saying that someone mastered zanpaktuo not knowing its shikai name side note the four stages as seen with ichigo are: - making sure who is dominant by fighting after wining allows to manifest the bollow mask to have some hollow power - adjuchas - achieved after hollow takes over theoritically possible to control after getting agreement from hollow - vasto lorde - achieved when you start accepting hollow as part of you then when the hollow "takes over" it looks not like a wild animal like in adjuchas stage but a like the hollofied person being veeeeery angry you can see it for example when they don't attack their friends/allies directly (they might still be affected by the effects of the fight) at this point should you use it the mask will look differently than when you were in adjuchas stage - unity - achieved by accepting the hollow for what it is part of you just like a zanpaktuo at this point you no longer summon a mask but shall you go bankai your form will change into arrancar like with some parts like your hollow form like horns maybe outward teeth or maybe in extreme cases tail or wings (at this point there is no "taking over" by hollow since it is fused with you it might still talk like zanpaktuo that it kinda is but there is no loosing control)

now that i though about it why does he have problems creating avalon? Other world part is covered by his own zanpaktuo as unlimited blade works quite literally brings your own world into existence onto the world outside so only a modification simpler than some which he has already done and the healing as shown with the void bandage is covered so why does he have problems with it?

there literally swords that give immortality and can heal anything and since he already created a sheath for his sword i recommend creating avalon the sheath of Excalibur from fate that way you can even keep loved ones safe by copying it as the unlimited blade works allows for creation of the same thing multiplet times

badly worded

by the way why they don't increase when he revolves? both evolutions gave him enough to increase his stats yet their rank didn't change

concubine? morgana? In what myth or legend?

not obscurus?

so this world has a madman that created universal level bomb arguably multiple times

That is one way but not the only one. By utilizing and reaching the limits of your body you become more in tune with it and you can do that by also for example meditating for a lit of time. The point is that for touki you need to feel your body's power and there are many ways to do it. Senjutsu is being in tune with world (especially worlds life) while touki just with your life which can be the first step of senjutsu or can be achieved by utilizing senjutsu.

doesn't devil teleportation take time?

while on the theme the arkham asylum with its sooooooo many faults would have been considered not fit for and asylum? Some versions i would say that the workers, owners and whatever would have been arrested with some even possibly getting the death penalty (lets just say they are can be as bad as joker while being technically mentally sound) so why was the arkham was not closed while the villains and other patients relocated?

it is literally canon when you get arceus he says something along the lines of "you have proven yourself you can have this part of my power" and it os canonical that arceus created the world with a "thousand hands" which are most likely the arceuses that we get in games
