Obito

[ANBUITACHIUCHIHA]

What if madara gets defeated and obito becomes the bijuu jinchuricki.. And yes I understand for that to happen kakashi most likely will die

 

[Zuru]

Then Obito will die to Plot no Jutsu too, not that hard of a question. :|

 

[Kettei]

They would still find a way -_-

 

[sagedog]

Obito has plans.................

 

[Flawž]

obito will become the 10 tails jin.

 

[Naruto D Luffy]

Then kakashi will stop him.
