MCs abilities

Soul Concept : The core of the existence of a being,in it is stored everything that represents it,mainly memories and its conscience.It normally takes the shape of a flame/sphere of varying colors.

Similar to a cell,a soul possesses an outer layer and an inner layer.The inner layer stores what defines a being,its consciousness, memories,likes and dislikes,an original personality(which may shift when possessing a body but always returns to the initial point were the memories that caused the change not be remembered).This inner part also constantly generates an energy similar to mana,named lifeforce which even though is scarcer than mana,it is also more powerful.Its esentially what keeps a soul together.There exists a Soulscape which can be entered and represents the inner part of the soul.

The outer part of the soul establishes its shape and keeps the lifeforce created from leaving the soul.

When a soul enters a body,much like a gas,it expands to match it,and proceeds to take it over in a matter of seconds.It cannot move by itself and needs the aid of a body to do so,for example,if a soul possessed a robot,it would be able to control it,however if it were to possess a box,the soul would be conscious but wouldn't be able to move nor see.Through adept use of lifeforce this can be walked around.Once the body is destroyed and can't be "used" anymore the soul automatically leaves it.

Memories stored inside a soul aren't loaded automatically,which means unless manually forced when entering a conscious body such as an animal they won't keep their memories. They will return once the soul leaves the body

A soul may establish links with physical or spiritual things.

While a soul is esentially spiritual and can't interact with physical things,it can be solidified.When solidified a soul may be damaged.Lifeforce will be used to heal the injury.

Souls are highly malleable and through sheer will can be manipulated with close to no limits ranging from moving it to things like dividing it and forming them into different shapes.

Other being's souls may be manipulated but I have yet to set the rules on that,probably through contact but as the user improves he may get some range or something,or they have to use their own souls to do it.

Strong souls produce more lifeforce and it can be forced to do so.

Mana can also be stored in the soul but it won't work as a replacement for lifeforce. Lifeforce will probably be able to be converted into mana.

Weak souls or people with no control over their souls constantly leak some lifeforce which when accumulated sometimes form new souls.Lone lifeforce will eventually transform into mana to justify mana being in the air in most fantasy worlds with magic.Lifeforce is harder to control than mana.

Planned Abilities for the MC with souls:

Makeshift stand.

Lifeforce constructs.

By manually fragmenting his soul Mc will be able to possess various things at once,and stablishing an spiritual link with all his soul fragments he will create a hive mind.(Imagine the information network he can create with that)

Consuming other souls,gaining their life force and memories,etc...(Quirks are a physical body thing so he can't steal that but he can get their experience with it,so if he gets enough experience and understanding of a quirk he may be able to recreate a fire quirk with lifeforce)

Magic with the use of Lifeforce but that will probably be really late in the story and meanwhile he will stick with recreating quirks but these have to be feasible,if he can't use magic don't expect him to be able to copy Eri's quirk that basically rewinds time.

Creating a strong link between his main body and his soul that makes it so his body changes shape along with the soul.

[All this soul thingies will be updated when I get new ideas,feel free to give your own! :) ]
