Well I didn't mean for us to go into such detail but you made a good point but it can also be said Naruto grabbed him with his right hand and pulled him up. Only Sasukes right hand was free when hanging on Narutos leg so Naruto pulled him up with his right so he can hop on it. The sages power was more of my main point.Sasuke did that so his Amaterasu could be combined with Naruto's FRS but we see Yamato do that with his water jutsu with Naruto's Wind Rasengan against Kakuza. A filler went into more detail about if when Jiraiya was teaching Naruto how to be in synch with another (a toad in the training) to combine attacks perfectly. He used an example where he used fire jutsus with Gamabuta's oil when they fought Orochimaru when they were fighting Jiraiya/Tsunade vs Orochimaru. This is also shown when the Kages combined their attacks against Madara, it was Mei's water dragon, raton from A and Gaara's Sand if I'm remembering right. That doesn't mean Sasuke can take control of Naruto's orb.
Also Shikamaru/Ino/Choji were using their jutsus in union since part 1, it just got way better in compatibility in the war as seen hereYou must be registered for see links,You must be registered for see links,You must be registered for see links,You must be registered for see links, andYou must be registered for see links.
As for the pic you posted, if you look in that picture then you see Naruto's other hand is about just as high or higher than his other hand. Then when it shows the orb being shaped manipulated, Naruto's other hand is down while the one controlling the orb is still up. Look at Naruto's left hand being as high or higher than his right hereYou must be registered for see linksand his left hand is down but his right is up facing the orb hereYou must be registered for see links. I didn't notice that at first but thanks to you I caught it, Naruto controlled the orb and you helped proved that. Thanks!
@rest of posters I'll reply later but you guys aren't saying anything new so expect a counter later.
