Mettaton's strongest form! I guess it could be part of a small AU. My idea is that when you defeat Mettaton NEO, he'll be like "Did you think this was my REAL form? Well, think again!" Then he turns into this form. The more you damage him, the more parts fall off, until eventually, he's in his ghost form. Then he'll say: "Please don't kill me..." And you can choose to kill or spare him.
