Okay, here's the thing. Mad Dummy was possessing a Dummy. However, the unbridled surge of emotion bonded him with it and he became fully corporeal. That's why he becomes Glad Dummy. I assume something similar happened to Mettaton. Else why would he have been worried about you killing him when you meet him at the Lab if he literally could just inhabit another body? And you can kill him, right? And Alphys goes missing?
