Killer!Sans is very thoughtful but not to the point of feelings. At the back of the shoe are two lines the upper line being black and the lower line being white. The shoes are the same color as his hoodie with a black line at the base of the shoe that goes to the front separating the blue shoe to the white front piece. His shorts are white with black stripes and he wears shoes instead of slippers. His hoodie is a paler blue to classic Sans, with ruffled tan colored fur around the hood, at the bottom of the hoodie is a sort of trim with a darker blue, (the hood itself is also the same darker blue) on the left side of his hoodie is a black stain (either his blood/liquid hatred or something else). (Most likely to stand out from other Sanses) Killer's alternate attire has him wearing the Sans classic striped shorts and sweater but with an inverted color scheme, he still has his target-like soul. He looks much like Classic Sans, but with a red target-like soul displaying, and liquid hate pouring out of his eyes. (Note: #3 is the most common route) Profile Appearance #5: Classic Sans brings back Killer's emotion and he stops his Genocide. #4: He is forced to do a Genocide run by Chara.
