Yeah, it is. When Mettaton becomes corporeal with his robot body, (you have to know he was a ghost previously, Alphys met him and made him a body) he actually can be damaged. (Mad Dummy tells you about the corporeal ghost thing) I think he didn't chose to become this form if his to defeat you, but to die in a body he feels like it's his. So, I really like the theory, the fight was dissapointing, though.
