Talk:Mercury vs. Mettaton/@comment-33346346-20180126025735

Mercury can definitely defeat Box Mettaton, and can possibly defeat Mettaton EX, though it's just as debatable for Mettaton EX defeating Mercury, but Mettaton NEO destroys him. Even if we haven't seen what Mettaton NEO can use to attack, we can assume that he fights similarly to Mettaton EX, with the addition of lasers. Mettaton NEO just has a massive ATK, even with his low DEF.
