I know i meant Bee can spin before they enter his body, since once they enter he's done. If they're done from long range Bee has time to react and spin them away, like neji's rotation.He's not strong enough to move his body an inch let alone like that. Hachibi does not do anything with his strength that he normally can't, all he does is keep spinning and build up tremendous momentum. But look at it this way. SM Madara has immense strength, a SM user can carry something far heavier then them i.e. Naruto carried Kurama/rhino and throw them distances away. Bee can carry things his own size and send them away. That means SM Madara is FAR stronger relative to his own body weight. So if he couldn't move his legs despite him having tremendous amounts of strength in it, Hachibi won't be moving his entire lower/upper body. I would like you to look at the scan again and see how many of those sand bullets didn't even hit Madara's bodyYou must be registered for see links. And that was NON-perfect Jin Gaara. Assume it's perfect Jin Gaara and he can easily do enough to engulf Hachibi's entire body. So you will need to prove Hachibi can move anything in his body apart from his tails and rear, which are not enough to create the momentum he needs to spin like that.
I think Bee just fired it at suigetsu. Bee didn't bother to change targets since suigetsu was just standing steady in front of him so he decided to took him out. A laser beam like that could be redirected like this if the target moves:Although I would totally agree with you that this would shit on Shukaku since the force it applies would demolish any shield he can put up, it is unfortunate for you that Kishi trolled this jutsu and allowed Karin to dodge it after it was already finished prepping.

Bee could just move his head and the beam just moves too. He didn't do it because he wanted to take suigetsu i guess
