If anyone had seen the Gztale oc soul. You would have noticed something very wrong with it. (I will eventually update the design of the outfit not the soul)

The soul has multiple cracks on it and they can't be healed. Second the soul color is two colors. Nobody has noticed or seen those three small details but...it's rare for someone to have two traits without a reason. Take notice Ghoul is a hybrid meaning since she's half monster and half human. Humans can't absorb monster or their own races souls. Monsters can absorb human souls. You can tell where I'm getting with this small explanation. Ghoul has the ability to absorb human souls but she can't do too many the disadvantage of absorbing souls is her original trait gets lost and disappears for temporarily times. Her soul cracks under the more pressure if she absorbs another humans soul. Meaning she has two other humans inside her body or soul. Her original soul trait is like a monsters white but it's upside like a human soul is. I will tell about Ghouls parents and past more in a book if I get a lot of requests for it.

Little spoiler art here :3

You're filled with GUILT

Ghoul never wanted this to happen but she had to do it or else...
Swap Papyrus now has a good reason to hate Undertale Ghoul is she as innocent as she acts or is she hiding something far more sinister? This is a good reason for some characters to either be scared or hate.
