Mettaton is an exception.

He is using that body permanently, with Alphys' help, which is why he can be killed with physical attacks -- also normally ghosts don't have a gender (although Blooky too leans towards male) however Mettaton chose his gender when he got the chance to attach himself to a permanent material body, by having Alphys come up with a male design.

So essentially Happstablook was still male-at-heart (soul?) even before he had a body, perhaps Blooky as well, although without a corpoeral form it's rather hard to follow social conventions. :P

All these are signs that Mettaton's soul is permanently attached to his body and it's not just a "host" for him. It can be damaged and its desctruction means his soul dies too, pretty much like all other monsters, and he is now an unbelievably fabulous and fully corporeal robot dude. :D
