Exactly. That must be blood, and Sans must have a physical body.

Sans will watch you push the world to its absolute limit and only fight you when there's no other way. He's pretty darn patient. Papyrus is a naive narcissist that truly believed that being kind to a mindless killer will make them change their ways. Also, they aren't the same person. Why are they even being compared.

Because Sans had the potential to be as kind as Papyrus--whose "narcissism," by the way, is clearly a front in order to seem tougher and less sensitive than he is--but chose not to. Both want what's best for the monster world, but predictably enough, the one who shrouds himself in mystery and conceals his true emotions is the one who eventually snaps.

Sans, Papyrus, Undyne and Alphys sweat. That's not unique. Toriel and Asgore have fur. Mettaton is a robot. They all eat monster food. That's not unique. They don't have physical forms, so magic is magic. Alphys is a recluse and lives off of ramen and popato chisps. Monster food isn't the same as human food.

I agree, and would offer two interpretations of this phenomenon: either Sans is a monster who drinks surface-world ketchup (which is feasible, since surface-world food items do end up in the underworld) or he's a human being. Why else do you think the red stuff in Sans' stomach wasn't absorbed upon consumption?

If he's bleeding, you're assuming he's human and that he has any use for blood in a skeleton body.

Skeleton costume. Remember, if Sans were Ness, he would be the Ness from the Earthbound Halloween Hack and not the actual game. This would explain why he wears a skeleton costume.

Moreover, there's also the possibility that the Phase Distorter dissolved Ness' physical body, since organic matter isn't supposed to be exposed to it, with the costume staying together like Alphonse from Fullmetal Alchemist.

Thus, even if we can't prove that Sans is human, he could still be Ness in some fashion. It's another possibility to consider.

Papyrus, another skeleton that is closer to actual human proportions - why not him? Does he not have enough mystery to him to fit your theory?

His head pops off and he keeps talking. He's not the one with the mysterious badge. His torso is clearly skeletal, but Sans' is obscured by a sweater. Next query.

He does that "breathing" (you realize his mouth doesn't open, right?) thing in genocide only.

He has a nose. People can breathe through their nose.

He's juiced with DT
