Long ago, when humans and monsters coexisted, humans feared the monsters' magic and started a war. They sealed the monsters beneath Mt. Ebott with a barrier, and it is said that seven human souls are needed to break it.
ATK: 1 DEF: 1 The easiest enemy. He won't be able to deal even a single point of damage. A skeleton monster. He never gives his best, living by the motto that doing just enough to get by is plenty. There's a reason for this: he knows Guest can reset time. His hobbies include sleeping, slacking off, and teasing his brother. Magic: Bone summoning, Blue Bones (don't move), Gravity manipulation, Attack prediction, Gaster Blasters (unlikely to be used). He's too weak to deal damage, but you'll be knocked back instead. Male.
Sans's younger brother. He was originally obsessed with capturing humans, but he has become your friend. Male.
A Royal Guard who uses spears. She hired Sans to be a sentry, but his constant slacking causes her no end of stress. She has no mercy for humans. Female.
While heading toward Waterfall after your non-battle battle with Papyrus, you encounter Sans.
You nod your head.
You ask him what he's doing here.
