I'm not really seeing why Shiggy would still be able to use his extra limbs upon any form of contact with Buffa's arsenal.
Well, when I said full body control, I meant it. Shigaraki's body constantly grows, adapts, evolves to find the perfect form depending on his situation.
For example;
When he was outnumbered, had his powers nullified, and got his ass handed to him, he sprouted these giant finger-tentacles and covered the entire flying coffin they were fighting in to control the flow of the fight, separate his opponents, restrict their mobility, and immediately gave himself the upper hand.
When he got poisoned, he spat the venom out of his body and sprouted these giant finger-tentacles with giant mouths to spit the venom out from his main body, and back at the guy who poisoned him.
When his finger tentacles were getting dismantled and he was taking a lot of damage, he took on a defensive form, creating reinforced hands all over his body to act as armor, and started tanking everything.
Honestly I don't think there's a reason to believe that the guy who can control his own flesh, constantly adapt and change his own body to match his environment, and do all of this WHILE being under the effects of a power-nullifying ability... for whatever reason can't adapt to his muscles relaxing and going numb.
Firstly, the scan does show that he still got affected by it for a small moment. So anything and everything the poi-zom has would already be applied to him by the time it enters his system
I don't think it does? He spat out the poison and sprouted giant tentacles while laughing at Suneater's audacity the very same moment he got stung. Also, this was a quirkless Shigaraki, this flesh manipulation and body control stuff is just his natural thing. Buffa would have an incredibly hard time landing hits on the guy when he can...
Predict the movements of people who are too fast for him to perceive.
Adapt to become fast enough to keep up with guys who are not just normally faster than him in their base form, but are also using several blitz amps to become even faster.
AND he can become fast enough to catch the SAME guy off-guard despite him having a form of precognition (Danger Sense) on top of his speed amps.
(Even if Buffa matches this speed instantly, he's still gonna struggle keeping up considering Shigaraki also snatches away Danger Sense)
And also use an ability that allows him to track someone's very soul and constantly scan them for weaknesses (Search).
If Buffa also grows to match his increasing stats, Shigaraki can take advantage of this by nerfing his own AP while severely buffing his durability, so Buffa would be pretty much invulnerable to physical attacks, while being significantly weaker in physicality. This scenario would be perfect for Shigaraki to either decay him or take away his abilities.
Even his mouth things are able to spit them out, the acidic part can still damage him as they try to get them out, while the effects of the poi-zom would kick in with or without the poison itself as long as it has been administered already.
I full heartedly disagree that the acid is gonna do any real damage, but even if it does, it's not something that would negate his regeneration, so Shigaraki would heal before even taking any significant damage. And the effects aren't really gonna do much either, since Shigaraki would either cover himself in his finger-tentacles to shed a new body (that also generates a massive explosion btw, could be useful to push Buffa away), or he'll just morph into the flesh fortress and shed safely inside there, while cutting off any other parts of his flesh that have been contaminated.
Secondly, they aren't just stings, they can vary from that to whole ass slashes. Coupled by the fact a chainsaw can rip and tear through flesh rather easily, he'd have a harder time dealing with the poi-zom, especially since the part that's ripped apart wouldn't be able to grow mouths while it's being shredded.
He wouldn't be able to have any interaction with any part of Shigaraki's flesh APART from his main body.
These giant tentacles? They're 100% fingers, each of them can use Decay, so even touching them is gonna be insta-death. And the decay can transfer from the chainsaw to Buffa's body. If he even stands on it? Dead. His vines touch those things? Dead. And if you're wondering how Mirko is standing on the tentacle in the scan, it's because Shigaraki's powers were disabled, including Decay.
(Or if Decay doesn't work, All For One can snatch his resistance away)
Same goes for the flesh fortress btw. All of that can spread Decay under normal circumstances. Shigaraki is effectively untouchable in this form.
Shedding may work if it hasn't spread to the 'new' parts of Shigaraki's body. Otherwise, the effect would still persist. It does have the problem where those new parts are wide open for stray vines or some other attacks Buffa can dish out. So there's that.
If the effect can only be spread through the vines, Shigaraki would know this via his "Search" ability reading Buffa's weakness. He'd just spam those arm tentacles or whip out the flesh fortress and he's effectively immune to getting touched.
Problem is, his resistance extends to the energy hands and vines, since those as well as other equipments from Geats are able to trade blows with the chainsword and left-hand gauntlet. Cutting the vines via other means are fair game.
If you mean his deconstruction resistance, I don't know if it applies here, considering he gets the resistance from resisting poison? I don't quite understand the justification or the clip on his profile. But either way, I don't think the vines are gonna able to attach themselves without getting blasted away by an Air Cannon.
Another thing I noticed is the deconstruction and other resistances are based on biological manipulation? If his powers and resistances are biological, then Shigaraki would actually be able to steal those abilities and use them for himself.
Buffa (and other Geats Riders)'s regen neg are simply just regen neg. Their attacks can just negate the regeneration without any further explanation. They didn't alway have this at first, since they initially couldn't kill off the
Jyamato Riders that could regen from becoming ash (
Kamen Rider finishers usually do not leave traces of the enemy save for dust I guess),
until they could. So yea, even a slice can be dangerous since you can't regen that injured area anymore, though Shigaraki still has a fighting chance as long as his really vital parts aren't hit. And I'm not sure how this interacts with him shedding his old body for his new one.
Interesting. Seems rather ineffective against the flesh fortress, but I wouldn't count on him getting close considering Shigaraki would absolutely try to range-spam him off the bat. Even if he gets close, the regen negation would have to be his first move because Shiggy's immediate response to being in a slightly disadvantageous position is spamming an infinite mass of hands.
Buffa should scale to Geats' DC, where the latter can explode
two gigantic enemies on separate occasions. Both monsters are
type 2 in size at their max peak (since the latter monster can grow in size).
Interesting. But the first one would be unlikely, as Shigaraki would immediately swat him out of the sky or blast him away with a Heavy Payload Air Cannon, and the second one seems to take a while to charge up.
As for the air cannon, his vines should be able to wrap around any available part of Shiggy. And if that fails, his energy hands save him by being graspy hands, which would benefit from Buffa's Desire Amp of Shigaraki's stats. His resistance to decon should allow him many more tries to return up to Shigaraki's mass.
Again, not so sure about the vines helping his maneuverability considering Shigaraki's spammable range options. But even if he resists Decay, he's gonna have a hard time making it up the mass without getting his power snatched.
