Something New is the AU of origin of the popular Killer Sans. In the AU, after many Genocide runs, Chara convinces Sans, who wants to feel something again, to try something new and join them in killing everybody. While at first, Sans somewhat struggles with it, knowing that it will be forgotten upon the next reset, he starts to feel less and less the more he kills. Eventually, this leads to his soul becoming like Chara's, and him permanently crying black liquid.

Though the comic does not show how, Killer managed to get a reputation among the Multiverse at some point, as shown in the comic taking place in Underswap.[1] It should also note that the AU technically ended on a open note, allowing for multiple interpretation of how his story ends.[2]
