The Bad Sanses are a group of Out!Code Destroyers that aim to achieve a similar goal to one another; to wreck havoc among the Multiverse and its AUs (Alternate Universes). The group mainly consists of Cross!Sans, Nightmare!Sans, Killer!Sans, Dust!Sans, Horror!Sans, and Error!Sans. Because of their goal of harming the Multiverse, the Bad Sanses happen to be the enemies of the Star Sanses; a group of Out!Code Protectors that want to help the Multiverse, rather than hurt it.
