Killer!Sans looks significantly different than Classic!Sans. His jacket is colored slightly greyer than Classic Sans' jacket. Instead of having white cotton on his hood, it's a light yellow instead. He wears a black shirt with a turtleneck, and his red, target shaped soul is seen on the front. His shorts' colors are inverted from the normal black surface and white stripe to a white surface and a black stripe, and his slippers are replaced with sneakers the same color as his jacket.
