Dust!Dtale!Satsujin!Sans

the poor lost murderer souls that are stuck in this husk of a being :

Dtale!Dust!Dust!Sans
the leader of the determined Dust!Murder time Trio and he stands in the middle and he really wants to kill you he doesn't know what mess he got into but he doesn't care he just wants every single human dead

Dtale!Dust!Killer!Sans
He stands on the right and he really wants you dead he could be called a second leader buds he is the 3rd leader because Insanity!Dtale!Dust!Sans is stronger than him so

Dtale!Dust!Killer!Sans (dead)
insane and Evil he hates the human he will end him even though he had barely any time to feel anything for Chara he start to feel feelings for Chara even going as far to say that he will bring her back once the human dies but he is dead so the shards of him is the husk being used as the body

Insanity!Dtale!Dust!Sans
He is the 3rd leader he is for backup he wants a human dead no matter what
