The Merciful SOULS is an AU similar to the original Undertale and may be mostly head-canon, rather than being a full AU. It still takes place underground and the same characters are in the same roles.
Notes and changes
- Sans is Papyrus's adoptive sibling. They are not related genetically.
- W. D. Gaster was Papyrus's father.
- Frisk is blind.
- Chara guides Frisk but does seem to have some murderous intent.
- Sans and Alphys know each other but don't seem to get on well.
- Sans drinks and may be an alcoholic.
- Sans's magic eye is unique to him and not a normal thing for skeletons.
- Frisk's first run was genocidal up to Papyrus where they reset.
- The second one, which is more focused on in the comic series is a pacifist one.
- Although Frisk is blind, the monsters don't seem to notice it.
- Sans is particularly responsible for W. D. Gaster's 'death', which is why he drinks.
- What happened to Sans's parents are a mystery, Papyrus just found him in the snow outside of Snowdin.
