The two Zeno sama are rather two very unique characters in the Dragon Ball Super. They do not fit in the known categories of strong characters.
Rather, they made a new category in which an OP entity can erase Universes by closing their fists. And yet there’s a possibility that Satan’s punch can make them unconscious.
The Tournament of Power was actually made just for the two Zeno-samas. If they weren’t entertained, there’s a possibility that they will erase all the participant Universes.
Even the Gods of Destruction cannot do anything to help their Universes. It is all up to the warriors to save their Universes and their existence.
It was mentioned before by Frieza that he wants to rule over the Zeno-samas and all the universes. Frieza actually plans to replace Zeno-sama and own all the known things that the Zenos own.
Well, of course, the first thing that was noticed by the viewers was Frieza’s unparalleled evilness and his unending greed for power. But wouldn’t it be more proper to ask if it is actually possible to replace Zeno-sama?
But before we come up with this question, let me ask you first, do you think Zeno is an entity that is Bajillion years old? That’s not a weird question at all.
You see, if Zeno is not replaceable, and if this whole multiverse is rather old, then he must be at least a Bajillion years old.
A God of Destruction can last for how many million years. Beerus even said himself that he had lived a million years as a God of Destruction. But even though Gods of Destruction can live long like that, they are still replaceable.
In fact, Beerus is not the first one to be the God of Destruction from Universe 7. If Zeno is unreplaceable, he would’ve encountered a lot of Gods of Destruction and saw them rise and fall.
This theory might be true or not. It might also be true that Zeno-sama is a replaceable entity. He is the Gods of Gods of Destruction, accompanied by his own angel, the Grand Priest.
It is possible that Zeno was once a God of Destruction that was promoted to be the King of All when the former was out of commission.
This second theory has a lot of holes than the first one because if Zeno is replaceable, Gods of Destruction would be more spiteful of him than scared.
Some of them might even consider grabbing his throne like Frieza. Of course, Zeno could just erase them in an instant, and if it goes like that, Gods of Destruction would be replaced for about a month or so (you can imagine how short it would be).
The omni king Zeno from dragon ball super because he could erase all of existence with one move, the only way he could be killed is if someone used the super dragon balls and summoned super shenron and wished for zeno to be erased.
But there are characters like Kami Tenchi , Azathoth , Elder God Demonbane , Truth etc are more powerful than him. I just said 4 of them but there are at least 10.
Zeno is not omnipresent nor omniscience. It is proved. He may be Omnipotent though. But as of episode 70 we don’t really know if he is actually Omnipotent.
He maybe just multiversal level reality warper. We don’t know much but the characters I talked about are all Omnipotent , omnipresent , omniscience. Some of them nigh-omnipotent.
Remember that there is around 15000 animes are out there so if you don’t know about one anime or if it’s not mainstream doesn’t mean it doesn’t has powerful characters.
But that being said Zeno maybe come under top 20 or even top 15 most powerful anime characters ever.
