Mabye the techiniques are just named the same??? The 4th's was a space time jutsu and had nothing to do with the lightning element. (as far as we know) So perhaps they're are jsut named the same by mistake. Anime is diffrent from the Magna.
Ok so if there are more than one of those necklaces then what were they for? Replacements? I doubt you would lose the necklace that gave you all your power.
Like I posted in the other one Kakashi is very kind to Naruto in Shippuden. He just took Sasuke under his wing, like Iruka Umino took Naruto under his.
I'm know he can use sand ( he used it to pick up Naruto's hand). As for how his abilities were affected, he probobly will have to defend himself from now on seeing as his bijju did it for him for a while.
1.Itachi
2.Maadara
3. Sasuke
This is going off what we know about each charecter. Maadara may very well be stronger than Itachi. Sasuke has the most potential.
