Soultale is an Undertale AU by Raytaygirl where the personalities of some monsters made them become the SOUL with a similar personality. The human's and Mettaton's SOUL is a white soul as they originally had colored souls.
Monsters who have not found their personality just have white SOULs. I tried my best to list certain kinds of monsters.
The monsters' SOULs
|Sans||Patience (Justice if Genocide)|
|Papyrus||Integrity (Bravery if killed)|
|Lesser & Greater Dog||Patience|
|Castellar||Perseverance (Lunacy if Genocide)|
