Sans *is* playing off of multiple roleplaying / stat-grinding game tropes, including being the only opponent that has a 'poison' effect, so it wouldn't be that surprising if he also had a shield, life steal, or life regeneration effect.

It is possible with one of those that Sans could survive his fight against the protagonist but that's seriously grasping at straws. We did defeat him, and honestly a couple of moments after the protagonist destroys the *world*.

Sans doesn't have 1 hp because he actually has that low health compared to others, the way I see it (although it certainly plays into a joke). It's just that at that point his health is insignificant to the protagonist. The last fight we didn't kill something in one hit was way back...
