I think you misunderstand something, my point is not to defeat Balancer through BFR, but if Diane needs to get rid of all of Balancer's terminals for the win then I don't see why Balancer doesn't need to defeat all of Diane's bodies, as they follow pretty much the same principle.
First time I hear about her having other bodies. What's that about? You mean on the physical plane, right? How many are there and where? Although Iwanaga's technique can affect all of humanity, so unless it's really a lot she might just get rid of them in one go.
That aside, can you tell me why a character with hive mind type 2 needs to have all other instances defeated to be officially defeated? After all the nature of type 2 hive mind has nothing to do with one existence in specific, but instead it involves many irrelevant characters that are not necessary to fight off Diane (they can share information and stuff but that's all), I don't see much reason for Diane to beat them as well (as SBA part about "Outside Influence").
It's not Outside Influence. It's the same character, whether that agrees with your philosophical view of what an individual is or not. The fiction's opinion that all terminals are the one entity known as Balancer supersedes. And the rule is that you have to defeat the entire character. And that's an established standard, even for hive mind type 2 in particular. There have been matches with other Type 2 hive mind and it's always that you have to defeat the entire thing.
And, honestly, imagine for a second we had some actual fighting scenario. They have some reason to fight. Like, say, who gets to own Texas. She defeats the terminal before her and 0.2s later another identical-looking terminal, with the same personality, memories, abilities and goals spawns in. That terminal thinks of itself as the same entity that was just defeated, acts identically and just seamlessly continues the fight for Texas.
Does that feel like she won the fight to you? To me that sounds like she is still fighting Balancer.
Anyway, point is, in no world is Balancer one particular terminal. Balancer is a decentralized system of non-physical computers.
Wouldn't it be more of type 1 Hive Mind from the way you describe?
It's an edge case. The reason I say it's type 2 is because each terminal apparently has its own memory space. The memories are typically synchronized, but Balancer's task is to exists each faction completely neutrally. To ensure that nothing can accidentally slip, one terminal can decide to not share some specific piece of information with another one. So they are all the same, except that terminals working with Shinto people would for example not know that the Mesopotamia guys send an inspector to them.
Regardless, they do have the shared properties needed for Porno to destroy said essence in common, every of Balancer's terminals or whatever they are called will get nuked alongside that shared essence presenting in one body.
Honestly, I still question the whole "oneness" thing regarding it. Like, the internet analogy works pretty well. Balancer is pretty much a programm running in the cloud. So, I still feel like her ability would need to be the type to erase computers instead of just the entity.
But let me put another argument in addition: Balancer has some pretty good pseudo-precog. Basically, he looks at every possible and even impossible choice someone could make and can then create countermeasures to all of them.
So, for a start, by SBA Balancer starts 4km away from her and, if there is a chance that her concept stuff can kill all terminals, he won't stay around. So it quickly becomes a cat and mouse game. Since she has to hit him, this isn't something she easily wins against a teleporting pseudo-precognitive. Heck, when in doubt Balancer can just erase a terminal itself before it gets hit. Or he could summon a god that can manipulate the flow of Type 1 information to just prevent information about his location form spreading beyond that location.
Now, Balancer is aware of concepts, minds etc. and by his ability to perceive the Ether flow he will get the information he needs. (Although there are also some gods he can summon, with abilities that give them knowledge)
That is to say: When Diane uses her ability to erase stuff once (or even before), Balancer will know it and begin developing a plan against it. And he has an option. You see, one of Balancer's conceptual abilities is to take a concept and manifest an entity from it. So, even if his terminals were not sufficiently conceptually disintinct he could create beings that are and have those fight.
Isn't power-null in this wiki kinda treated on the basis of the level of hax which it has shown to nullify? Especially in this case concepts type 1 is on the same level as type 2 info. If we stick to that way, then neither can Balancer affect Diane at all, since Dispel Bounds, which are conceptual type 1 in nature, need to be either blown away or straight up negated for any of Diane's body (including the material one) to be interacted with. Seeing concept type 1 cannot affect type 2 info and vice-versa, I don't see how Balancer would be able to affect Porno in the first place.
If you go with abstractness and based on that equalize info to concept, I have bad news. First, while not Balancer himself, all the gods he summons do resist that. And second, those gods can use true names to control things which is a layer more abstract. One thing that can be done with true names is to just use the power of the opponent against them.
However, I believe our standard is that powernull only works against things similar to what it has shown, unless a mechanism gives reason to assume the contrary. (With mechanism I mean: If your powernull works by conceptually erasing powers, then of course it works on all power that don't resist conceptual erasure)
That would further reinforce Delta's argument, lifespan being an element of an individual's whole record of existence, i.e their fate. And yes they are indeed capable of regenerating, negating, and resisting regen negation on that level.
Fate is one or two layers of abstractness below what Iwanaga operates on, so no it's not fate.
Diane doesn't need to resist the effect of getting her lifespan cut so it doesn't matter if said hax is irresistible , she only needs to regenerate the physical body though, as explained pretty much above, from lower-tiers so the regeneration layers scaling is quite thick and it isn't the same as hax potency/layers.
Nah, that doesn't solve it because whatever she regenerates has a lifespan of 0, meaning it's already dead and erased. There is no physical body without lifespan. In case I wasn't clear: Iwanaga reducing lifespan to 0 erases things. They don't just die.
She can since her attacks would erase beings who have the exact same physiology (of multiple bodies scattering throughout different planes).
I mean, the reason we assume Balancer can't get on those planes is only because they have a different nature from the information plane he
can get on. So the situation is symmetric.
