Either With Naruto's help or By Sacrificing Himself. There's a reason why Kishi Has kept Him Alive Still. If you can't see that there's no hope for you.
Yet thats why he is still alive cough cough read the manga again coughUm he's already been sacrificed to revive Madara and um... *cough*fanboymuch*cough*
black zetsu is nothing to the 10 tailed. Rin flashback is all he needs poof zetsu's dead.black zetsu is controlling him and if maybe just maybe obito enter in control of his body i think black zetsu can stop using obito if he wants or if he dose not like what obito is doing.
ya and you must forget how kishi roles. he has been making obito like naruto more then any other character. like i said naruto and obito can stop madara or obito alone THE ENDObito is currently being used like a puppet by black zetsu of all people.
He might be able to help, or give an opening to defeat Madara, but last I checked Naruto was the main character.
Finally a smart replyI agree, if he was able to stop the ten tails take control of him then I don't see why he couldn't do the same with black zetzu
