Alright. Im gonna go through them all and give scans for each issue that is an inconsistency.
So according to you guys and Yhwach, the power null is passive because any power that he sees in the future, he understands. And any power that he understands is a power that can't be used to harm him . Like I said before, this is blatant power null. But there are several issues with it being used passively instead of being used as a thought based power:
Ichigo & Renji vs Yhwach
This is the simplest inconsistency that I dont think was brought up before (or if it was, I don't remember). Despite having the Almighty activated, and using it in battle, Ichigo and Renji were never power nulled by Yhwach and both were very capable of going against him, especially Ichigo. Evidence:
-Yhwach seeing into the distant future at all is evidence. He would have seen everything Ichigo and Renji pulled off against him, understood their abilities, and had them nulled before any actual encounters happened. Period. This is especially true in Ichigos case because of Getsuga Tensho and Grand Rey Cero (which i'll show in a bit). If Yhwach is able to see thousands of years into the distant future, he would have had absolutely 0 problems passively nulling any opponent he would've taken on in the future.
-Yhwach actively deciding to pit his sword against Ichigo's new sword . He wouldn't have needed to do this if Ichigo's Zanpakuto was already passively nulled.
-Ichigo successfully using a Gran Rey Cero infused Getsuga Tensho against Yhwach . Also wouldn't have happened if Yhwach passively nulled Ichigo's powers.
-Yhwach actively deciding to break Ichigo's new Bankai . As well as deciding to not only break Renji's Zabimaru , but also break Ichigo's sword again a second time after it was restored, and only particially at that . Same thing with Renji's Zabimaru a 2nd time .
-Yhwach actively breaking all Bankai's in the future and even making it clear he would kill Renji for opposing him. Why would Yhwach need to do this if the Almighty passively nullified an opponents powers? The Bankais would have already been unable to be used to harm him if this were true as he would have seen them in the future and understood them, yet, Yhwach decides to destroy them.
-Ichigo successfully using another Getsuga Tensho on Yhwachafter stabbing him with his sword , and harming and even killing Yhwach to the point that Yhwach needed to rewrite the future to rewrite his death in order to come back . Yhwach blatantly had the Almighty activated and Getsuga Tensho was able to kill him to such a degree. This would've been impossible for Ichigo to pull off if Yhwach's power null was passive.
And this isn't where it ends.
Uryu vs Jugram
Another inconsistency that has problems with the Almighty passively nulling powers. And no, the Almighty isnt any different from Yhwach's when Jugram uses it during his slumber, the almighty is literally just being switched over to Jugram when Yhwach sleeps. As Jugram says, he is a vessle for Yhwach's power during slumber. So the Almighty in Jugram's possession is exactly the same as it is in Yhwach's. Anyways:
Jugram had the Almighty in this point in the manga, and despite having it activated already when confronting Uryu , Jugram didn't power null him with it. In fact, Uryu fights Jugram just fine . And before anyone hits me with the "Jugram doesn't have full control over it like Yhwach does", that's the point. Jugram not having control over it is exactly one of the reasons why the power null isn't passive, but active. Passive abilities are not determined by how much control you have over them as that goes against the point of them being passive in the first place. Passive abilities are used just by having them, thats it. So if the Almighty needs to be properly controlled in order for the power null to be used properly, that would be more reason to think it's active based. And speaking of Uryu...
Uryu's Antithesis
This is the last of what I found and is pretty simple enough.Uryu's Antithesis is canonically implied by Jugram himself to be a power that can oppose Yhwach's Almighty .
See the issue yet? For multiple reasons, Uryu's Antithesis would be a power that Yhwach would clearly know about and understand. So its supposed to be unable to do anything to him because of the power null being passive. Yet, Jugram blatantly says that its possible for it to be used to turn on and oppose Yhwach's Almighty.And Jugram understands how the Almighty works . Why would Jugram even imply something like this when the Antithesis would've long been automatically incapable of doing harm to Yhwach? This, like Ichigo killing Yhwach with Getsuga Tensho, would be impossible unless the power null is not passive based.
That about does it. Just so none of you get confused on what im arguing, Yhwach having power null is fine. Its only the functioning of it that im disagreeing with it. For all the reasons I laid out, it should be active instead of passive.
