Sorry if I offended you. I didn't mean to. Just, you write several replies even though you can edit one of them instead. Plus, 'Omniverse' is different in many forms of finction. In DC, it's several Multiverses that don't interact with each other (like DC comics and Arrowverse). In Ben 10 is Multiverse/Alternate Timelines. In Marvel it's all of fiction and there have been crossovers with DC, Invincible and many others but they are usually one time thing.
And even then, there is no confirmation fiction creators wanted to make themselves dieties.
