Eh, maybe- late 2012, but Kidomaru NEVER covers his whole body in the armour. Pores don't appear in certain areas or he needs those areas free to fight back- Sasori will have him totally surrounded with puppets.
No, since day one. I've been, if not the original, Orochimaru/sound fanboy.
Sweat glands are basically distributed over the entire body, there are few places here sweat glands aren't located (ears, nails, and lips). Again, you're stating he doesn't cover his entire with NO proof. There is no reason why he wouldn't and it was never stated that he couldn't.
Again, you have yet to explain how those puppets bypass his web. While you claim to know Kidomaru, you must not know much about Sasori and his style of fighting. While controlling puppets, he can't use any other weaponry in his true form. Having to use chakra, Kidomaru's chakra enhanced webs hinder the performance of the puppets.
Part 1 Neji in the DB was a 4, Sasori is faster at 4.5. Kidomaru was getting overwhelmed by just Neji in close combat and had to resort to his spider. 100 puppets easily overwhelm him and his spider. He isn't beating 100 puppets alone with his spider.
No.
Speed in the databook includes foot speed and reaction speed. Sasori has shown NEITHER! The speed he has shown was In relation to his hand speed, which was easily predicted by Sakura after briefly analyzing his battle style. You can't compare Neji's hand speed to Sasori's hand speed. That's utterly ridiculous.
Kidomaru was never overwhelmed his Neji's close combat, something he wouldn't have to be concerned about against Sasori anyway.
