I have decided that the universes that will collide will be the one from the original trilogy, the one from One Night at Illuminati (but only with the presence of Soluigi from the video game Soluigi Story), the one from the Jonny Pizza stop motion saga which includes the two spin-offs, namely One Night at Super George, and the two video games, namely Soluigi Adventure and Soluigi Welcome to the Francyverse, and that's it.
