SOUL - term used to describe a set of: emotions (personality), mind (knowledge and calculations) and free will (independent decisions). SOUL is constantly powered by determination that derives from emotions. Only the Player (a.k.a. the User or the Human) have Soul. SOUL cannot be lost, taken away or given.

This is my definition of soul, a part of a bigger thing, made to better understand what Chara really is. It is simplified version because of my lack of knowledge and poor english. It isn't a theory because it is based on real life conditions (external point of view, can be only improved) not vague informations derived by game (internal, limited point of view). It really helped me to better understand Undertale, even to completely redefine its components from scratch (e.g. Soul or Chara, Frisk, monsters, their purpose and relations) and finally to see how useless they are. That's it.
