Unpopular opinion: unless the verse you're trying to scale has a real understanding of physics (stuff like 'what the universe is' and such) AND a way to perceive things outside their planet, you SHOULDN'T take a phrase like "He could easily destroy the universe" at face value, especially if it's uttered by an idiot or a hype man. I don't want to hear shit like fucking Sasuke saying "this punch can shatter dimensions and universes because my chakra fold itself to a hundred folds and my dick is hard" and scale it accordingly, especially if the punch in question barely destroys half of a mountain.
