Nightmare-sans: consists of black liquid (slime), skeleton, loves the negative suffering but loves his daughter...
Killer: He likes to make stupid jokes sometimes, he looks like a regular Sans... He's just wearing a black T-shirt with a blue down jacket... And on his chest is a target mark (that's his soul)
Dust: a schizo... Lost his brother... Papyrus... Appearance: looks like a regular classic Sans but with black eyes and blue-red pupils, wears a hood
Cross: Well, he looks like Sans and that's all, except for the scar on his eye and the red color of his right eye, and also the medallion with the yellow heart.
Error: glitchy sans... Black♡... Voice is glitching... There may be glitches on the body in the "error" sign. Loves chocolate, controls blue threads.
Horror sans: the eternally hungry sans... ... There is a hole in his skull on the left side...
Dressed like a classic Sans, but the horror has blood on his white T-shirt... The horror has one red eye.
and they are all cute skeletons♡
Nightmare Sans, or rather your father, he is the boss of all these pranksters.
