I'm sure if Kishi said he has no weekesses at the moment then he doesn't no matter what u say bro u can say what if all day but Kishi is the author not you....
that happened with zetsu because zetsu doesn't have the power to surppres hashirama S dna + naruto s presence unlike yamata which had enough power to surppres it also the same thing goes to tobi and madara however zetsu only has power to surppres hashirama dna only not with naruto pressence
