Mettaton is made of metal and magic. His body is a marvel of science. Every joint is expertly designed to precision, from the minutest of twitches to the largest of gestures. He is heavier than you’d expect, but capable of feats that might lead you to suspect he is as light as a feather. His physical form is a work of craftsmanship, the pinnacle of monster kind’s achievements, second only to the CORE.
And with the sheer force of his repressed rage and with reckless abandon, Burgerpants would absolutely obliterate him.
