maybe they headbutt eachother on purpose
anime does it all the time

I don't think it's an actual headbutt. It's probably just symbolizing that those two are going to battle "head to head" next fight, in a manner of speaking.

thats what i meant

i didnt understand why would tobi pick both sharing /rinnegan when its supposed that rinnegan its the evolved side of sharring but then if we think about their abilitys we see that they got complety different things.

So we have toby whit whit sharring and rinnegan powers that makes sense now.but unfortunatly its sadly that byakugan its so underrated

hes not at full power

and still, tobi's real identity is still concealed

when willl we know!

according to tsunade, he is the 2nd madara

She said hes madara as an illusion of a powerful name

Well Madara is a fucking bad ass Pseudonym.
I don't think he's the second Madara considering that Kabuto called him "fake" Madara.
I think he found out about Madara's secret before Oro and Kabuto did.

no , i still think madara is madara and tobi is a clone of madara infused whit first hokage cells , cuz if you remember the fight whit konan he says something like 'i stole a part of first hokage dna' or when he was talking whit kabuto about the new eyes saying he gave them, most of the actions that madara said that HE did , happened to be same as tobi whit a bit of deviation , yet they both got the same plan ( or they had) , we know both knew nagato , we know both have memories of fighting 1st hogake and survive that and we know that before his dead madara unlocked the power of six patch that means he also unlocked the dead and life one wich could easily allow him to pull some magic trick.


But yet... theres so many questions left like why tobi never showed sometimes else than a normal sharingan ( even on the bridge of death vs konano he prefered to sacrifice a eye using izanagi ) but yeah.. theres alot of chapters to be done and i dont think the autor willl reveal any time soon whos the realm toby
