I believe that the underground, because of the barrier, is sort of tucked in neatly in its own state of existence, where magic on the surface ceased to exist and died out, the barrier kept all the magic underground locked up and safe. This abundance of magic could sort-of supercharge all beings that fall, making all those who fall to have the ability to perform certain feats of magic, and the fact that magic is consumed via the undergrounds food supports that magic can be infused into humans. The red soul may be DETERMINATION or free will, and the others all their respective traits, and charas soul ,which is red, may be determination, or something similar but a bit different. self confidence for example, or even something like willpower. Chara has no definitive soul trait or colour, the only evidence of their trait being them stating that they had determination. which all the souls have, in different concentrations. with the right amount of DETERMINATION to shape the magic around them, they could theoretically alter their surroundings, state of existance and even their timestram. If all the things in the undeground are made of magic, then humans with a lot of DETERMINATION to change that magic could do so. This also helps the fact of souls persisting after death. If no human soul dissapead after the owner died, the surface would be littered with them, seeing as humans cant absorb human souls- it must take a certain amount of magic for the soul to persist after death, or to be visible after death. These were just children, and they all would pray do not die, but their small amounts of magic not srong enough to bring back a form, or turn back time. They just kept on existing. This is where the difference with chara could come in. They had more willpower and determination to do what they wanted, and to save the monsters than the other children. Their magic built them a form for their soul to possess, like a monster- they are just magic shaped by a soul. Chara themselves could not sustain the form, as human souls are not meant to have a magical body, just as monster souls are not meant to harbour a physical form. Chara could not keep it up, and faded into a slumber. This is what i believe they meant by 'you have awakened me'. Now, frisk must have had an extrordinary amount of willpower, or DETERMINATION, as they had the ability to use it to change time, and bring themselves back.With this excessive amount, chara could have leeched off of the effects and remaining DETERMINATION, which could increase with LOVe, giving chara the ability to not only rekindle their conciousness, but also too create a form.This is only the left-overs that chara posseses, and yet it is far more than they themselves could sustain. Which is why they want frisks soul. They could have enough determination to exist properly.

at least thats my theory on souls , DT and chara and frisks relationship
