I really wanted to create a thread on this. Because I think Spoiler 3 is real (the pics are and they match the spoiler). Thus I think a thread on Itachis jutsu is kinda appropriate. But there's still a chance it's not accurate. Well we'll see about that.^^
So Itachi split his power with Naruto. Yah. Something's off.
First of all since when was sharing your power common enough to have no need to be explained at all?
We've seen Sasuke use an implanted Amaterasu on Madara. That was awfull enough, but since both of them are brothers and sharingan users it was sort of believable. But there were no further explanations except for Madara's 'oh i see he must have implanted amaterasu..' like it's something obviously common to do.
And now he's supposed to have shared his 'power' with Naruto? That's awfully inconsistent. If this was possible all along then why not just have all sorts of powers transfer to yourself? This makes Orochimaru's pursuit of a kekkei genkai look totally stupid.
Okay there's still the possibility that Itachi was the ONLY one to actually develop a jutsu which lets him transfer his own jutsu, powers, aids or whatever. (No we actually have to assume he was the only one otherwise a lot of things wouldn't make sense. Though I'm really disturbed to see Madara react like it was common, logical, blah.)
But here's the next contradiction.
How could he transfer anything to Naruto, by just meeting his Bunshin? That may be presumptious of me, but i always assumed that Naruto pulled a Tayuu-Kage-Bunshin and let his CLONES handle the exploration while his true self stayed SAFE with team konoha.
Wasn't that idiot supposed to stay at least by Hinata and Yamato? Being Akatsukis primary target and all.
So basically any physical transfer is nonsense, because Naruto only gains their experienced memories. Which means UNLESS Itachi genjutsu'd the bunshin teaching his subconsciousness some sort of jutsu or he actually encountered the REAL Naruto this whole transfer is a pile of crap.
What do you think about this Sharing-Power-no-Jutsu?
All sorts of ideas and theories on his jutsu are most welcome. (Unless they're in any way realted to obito or another equally annoying theory)
