I really don't understand this logic. You're quoting supernatural powers like running across thin air, ignoring bullets, punching through ridiculous layers of steel, using nothing to fight something, tank incredible hits and move superfast..

..but you're going to call a supernatural ability bullshit? What? You can claim it's metagame but Gonad himself doesn't gain any actual knowledge. He doesn't know what your character can do, he doesn't gain any insight. He has a supernatural ability that allows him to increase in might to match the peak performance of the opponent, forcing them to use their peak. Leveling the field to a battle of actual skill and not "My powers are infinity and yours are punching things therefore you instantly lose". That is as much metagame as "You use fire magic so I use water magic, we're even!".
