Obito syncs with Demonic path

[TheWillofFire]

Madara of course planned everything, afterall he was for certain Obito would come back
(Madara chose obito because he had the chance to, not because he was planning on him from beginning he had lots of things set up)

We all know Madara is synced with Mazou

Tobi once considered syncing Sasuke to mazou when the time came (its in manga forgot what chapter)
And also Im sure madra wants Obito to be fully synced.

I mean the roots are already syncing to him (remember zetsu a part of mazou)
When obito getting his MS, we see the roots, be loose, then all of a sudden twists to the eye
maybe to show a form of syning to the mazou?

I don't think he got synced to the Mazou just then.

Though I admit he sounded like the Mazou with all the "WAOOOOO!!!" stuff

The mask twist to the eye because that's how it was normally. Zetsu was just giving him full protection because he knew he was about to go on a rampage.

[TheWillofFire]

I dont mean for him to be "fully synced" but just "partcially" afterall he now is using tobis complete form instead of it being lose for the first time.

Can someone please explain what is meant by syncing with the gedo mazou?

[ObitoZero]

I don't think he got synced to the Mazou just then.

Though I admit he sounded like the Mazou with all the "WAOOOOO!!!" stuff

I'm pretty sure that was the Gedo Mazou Yelling. It does it earlier in the manga while entering the war with Obito: http://www.narutobase.net/manga/Naruto/537/3

Syncin to mezo = juubi wanting to be free, madara and obito want the destruction juubi chakra power to create their moon plan of peace
