Is still hard to beat kakuzu. I cant do with kushina neither with minato sb. To be clear, i never tried minatos barrier but i think at that point i can win.

As 1x1 i think kakuzu is the best, then kushina/bee and only then minato. But for those who have good stats in every 4 positions or at least 2 positions, edo minato can mystery every round while edo hashi steal chakra and... if you ignite kakuzu or even imobile him after remove his chakra, kakuzu will not be the 1 man army he use to be. Having edo hashi sb or madara founder sb like china meta is the cherry on top

So for me, the secret of edo minato is not having only position 1 stack (which is very hard).

About the naruto discussion, wtf.. mine is at the bench since i bought kushina. Noway my kushina loose versus 2x power naruto. And she only looses versus kakuzu because he attacks twice or because i dont remove his buffs
