Analysis: Paper Mario
Merloo is Dimentio It would make perfect sense, as we all know Dimentio can alter and even create dimensions and if you use your all knowing pixel to ask about Merloo's image, it will say that Merloo is a great magician and can control dimensions! Remind you of anyone? Of course it does, that is the exact concept of Dimentio. Going back to the image and upstanding theories, it says that Merloo is said to have written the Light Prognosticus and if we go back to older theories, there is the idea that Dimentio wrote the Dark Prognosticus. It would make sense he would have the power to create both.
