A uber entity is the highest level being. The strongest beings = uber beings. They are above every cosmic entity. The ultimate omniking god of all uber beings is Uber. He lives in the Uber Realm. Which is home to few other omni gods. There is nothing stronger than Uber and impossible since he is the apex of Absolute Infinity. By making an entity stronger than Uber, you will be draining its power from the apex. Meaning it will be weaker than Uber allways. It has been hypothesised that there exists Prime Uber, but it has not been confirmed since our minds are not great enough to be able to even see him. Even greater theorised entity Uber Uber, once stated that he is the Great grandfather of Uber, and the father of Prime Uber. But all of these are yet to be true.
