and assumes that her cognitive functions still resides in her physical brain.
Given that Tayzilla is rocking Endbringer 'biology' her cognitive functions
should be running on her Shardzilla, though from Panacea's examination Tayzilla is a sort of weird hybrid of Endbringer\Godzilla physiology, so the Endzilla material where her brain should be might be mimicking the form and function of a brain to some degree.
Of course, if that
is the case, then Tayzilla would
still be nearly impossible to mind control, because I
sincerely doubt that 'hybrid Endbringer\Godzilla material mimicking the form and function of a hybrid human\Godzilla brain' actually operates even remotely similar to a
real human brain, so attempting to mind control Tayzilla would be like trying to infect a Windows 10 machine with a Commodore virus: It's just not gonna work.
Tayzilla is only
emulating human-like thought processes, her 'actual' mind, whatever the hell it is, is very definitely not even
remotely human. And that's not even taking into account her Mecha transformation, which appears to
literally turn her brain into a computer without affecting continuity of consciousness.
If Cauldron had the ability to create specific abilities, especially ones that could control other Parahumans, then they would have done exactly that instead of the roundabout stuff (like letting a wildGray Boy run around with the S9, then using Glaistig Uaine to kill him to keep his powers, and then tossing her into the Birdcage). Vials are always complete guesswork (Number Man can probably give an approximate of what a Vial will likely give but even he won't be able to give a 100% answer).
Cauldron definitely couldn't create
specific abilities, but they were able to figure out a bunch of statistical stuff (presumably thanks to Number Man) regarding vials. The P, O and R values are mentioned as being especially important, with R being the reliability of a vial. Samples with low R values risk physical changes, or simply give wildly varying types of powers, while an R of 5 indicates a 3-4% chance of unwanted physical changes and a 0.5% chance of extreme mutations. It also indicates that the sample provides a broad category of powers, rather than a single specific power.
The O value refers to a power's 'uniqueness', how unusual it is for parahumans to have similar abilities. This is extremely subjective, though generally speaking higher ratings in this value make it easier to stand out as a hero or villain, while low ratings give simple powers already possessed by a number of other parahumans.
The P value refers to the average PRT classifications of a sample, higher P values mean more effective and versatile abilities. The P value is a series of labels on a graph, one label for each PRT classification that showed the 'expected range' of a vial's granted powers.
Sample T-six-zero-zero-one is used in-story as an example of a sample with a high R value, saying that over the course of 63 tests it granted some form of flight 61 times. Sample B-zero-zero-thirty is a low R value, over the course of 4 tests it granted the ability to make things implode, the creation of a powerful vacuum in a person's mouth that draws everything into a portal where it is promptly annihilated, and the other two times it killed the host.
Altogether, the three ratings are put into a 'cube graph' with P as the X axis, O as the Y and R as the Z. Doctor Mother says the following about that:
Interlude 12½ said:
"You could theoretically push into the seven range of 'P' values, to put yourself at this Madcap's level in terms of raw power, but you would be forfeiting a great deal in the other two departments. Your powers would be relatively simple, defaulting to the sort of abilities that countless other heroes already have… and with the low 'R' score, you would be risking getting something you do not want. Physical changes, perhaps, or powers outside of the area you wanted. Super strength when you desired telekinesis, for a crude example."
...
"If you decided on a sample with an 'R' score of five, I would tell you I could make no promises. There would be perhaps a three or four percent chance you would experience some unwanted physical changes. Zero-point-five percent chance that you'd experience changes of a degree that you wouldn't be able to go out in public without drawing notice, even with heavy clothing. You would, I'd venture, not be buying a particular power, but the broader category of that power. To use our earlier example, you would not be buying acid spit, specifically, but an acid power."
A 'clients' mental state, personality and background are stated to have a measurable impact on granted powers, presumably because while vials force an artificial Trigger Event they
do still force a Trigger Event with all that entails. (Specifically that the shard, broken and incorrectly configured though it may be, does still attempt to 'shape' a host's granted powers based on their mental state at the time of said Trigger Event.)
And it is also mentioned that vials containing the 'foreign element' are highly likely to produce extreme deviants that resemble nothing found in nature, three specific examples of such 'extreme deviants' are given: Eidolon, a defensive power utilizing warped space and the power to take over a nearby parahuman's mind, body and powers automatically on death. Cauldron speculated that such vials were sort of like the 'opposite' of the 'Balance' vial; totally lacking the restrictions that protect humans.
There's also
this quote from Wildbow, which may or may not help depending on how you feel about out-of-story Wildbow WoG's.
Wildbow on IRC said:
08:10 Panda: Fantastic. Last but not least: Noelle.
Panda: Deets on what her power was originally supposed to do?
08:13 Wildbow: Powers aren't supposed to be anything specific.
Wildbow: They're too variable in the results they give
08:16 Panda: As far as vials are concerned?
08:19 Wildbow: The vials are named in sort of a compromise between the observed results.
08:20 Wildbow: So her 'Division' vial turned up, say, seven or eight different powers in the course of testing.
Wildbow: A duplication cape that spawned off copies of people they could see (with the cape's memories/personality)...
08:21 Wildbow: A cape that could create 'pods' they could respawn from if they died within a certain range.
08:22 Wildbow: A case fifty three that could smear themselves over someone in a semiliquid state and then walk away with a share of that person's vitality and that person's features (no powers)
08:23 Wildbow: A cape that could, again, spawn off chunks of themselves that would then expand and eventually serve as deployment zones for their own low-intelligence duplicates
08:24 Wildbow: A cape that, upon touching someone, locked in on that individual's DNA and qualities, and then spawned off a roughly identical, loyal duplicate.
08:25 Wildbow: A cape that could absorb people to regenerate rapidly, at a cost of their own features/identity.
Wildbow: (and the life of the victim)
08:26 Wildbow: A cape with exceptional shapeshifting and self-duplication abilities.
08:27 Wildbow: Noelle's own neuroses and personality was liable to create something with a master and brute aspect to it.
Wildbow: Well, the brute extreme was largely her injuries
Wildbow: And the vial's own tendency towards brute/shifter powers.
08:29 Panda: This is very open-ended. I'm impressed.
08:30 Wildbow: Yes. Bask in my brilliance, please.
There is also
a list of different vial formulas and the parahumans or powers that they granted.
So while Cauldron cannot
guarantee specific powers, some vials have a sufficiently high statistical chance of granting specific powers that they are
effectively guaranteed to do so. Such vials cost
hundreds of millions to purchase, presumably both because they are the most desirable and because all vials are in extremely limited supply. It also sounds like the POR values are a bit 'give and take' in that a higher value in one usually (but not always) translates to lower values in the others, making vials with high values for all three categories very rare (and thus expensive). They can
almost guarantee the basic 'theme' of certain powers, like 'this vial will almost certainly give you the ability to fly somehow' or 'this vial will almost certainly give you the ability to create some kind of large remote-controlled construct somehow' but the details are always up in the air, and the more certain they are about some aspects, the
less certain they are about others.
Also, Tayzilla can't be pathed by Contessa. She likely also stone walls other thinkers too. Tattletale just gets a song from Blue Oyster Cult stuck in her head, it's a good song, so she doesn't mind majorly.
Tayzilla registers as an Endbringer, so yeah the vast majority of thinker powers do not directly function on her. Tattletale is actually likely to be one of the few exceptions, as her power is shown in-story to be able to figure out the basic physiology of Endbringers by watching Leviathan in-battle. That said, I believe she still can't get anything regarding
predictions of Endbringers; ie attempts to determine which Endbringer is likely to strike next\where the next attack will be just get noped.
Shards are also not familiar with Godzillas, so the 'shard network' doesn't inherently know what a Godzilla is capable of and thus only has whatever information that the shards can figure out from observational experience of Tayzilla's 'Godzillaness'. Which, considering Taylor has been examined by Shaper and underwent power testing, is probably quite a lot but not everything. (The Shaper examination is presumably how Coil's shard was able to simulate Tayzilla going Shin Tayzilla for example, as the 'Shin Godzilla powers' would be extrapolatable from whatever Tayzilla is using for genetics.)
