Nouon

Nouon (pronunciation: No-YOU-on) is an incomprehensible and maddening god. Nouon is a resident of a place similar to the Mad Realm. However the Meme Realm is a Structure all its own, with strange creatures appearing out of the primordial soup, growing incredible popular, forgotten, and dissolved back to the place from whence they came. In the mythologies of many universes, it is believed that Nouon will destroy Omniverse 65 by speaking N'ghoh-Ewuuu, a primal utterance (also the name of a powerful lord of the Mad Realm) that will reverse existence and destroy our Omniverse. Coincidentally, it sounds like the popular comeback "No u" that is believed to reverse any insult, suggesting that Omniverse 65 is an insult and affront to Nouon's existence.

Why has the phrase not been spoken?
Simply put, Nouon has taken a liking to our omniverse for whatever reason. Others have not been so lucky. In fact, Omniverse 65 is not the affront to Nouon. He did destroy Omniverse 66 and Omniverse 4867.
