Actually, no, we have an extremely great amount of proof that, for instance, Toriel is not Pikachu. There is no evidence linking Undertale to Pokemon, Toriel has no electric attacks, and she is very obviously not a small yellow rat.

On the other hand, Undertale is rather clearly connected to EarthBound, Sans shares at least one ability with Ness, and they also share the same body shape and posture.

I'm not saying that Sans is Ness, I'm just saying that there is a reasonable ammount of evidence that he could be, and no proof that he is not. There is a reasonable amount of evidence Sans isn't Ness. It's mainly the fact that stuff like Sans only having one hp makes no sense, and him not taking advantage of PSI attacks in order to defeat a serial killer makes even less sense. That, and this being "the big secret we were supposed to find" as Matt put it, would be copyright infringment.

Yes, both can teleport, and yes, they have similar poses, but I don't think that's enough to call it a legitimate possibility.
