Hashi z considered as 1 of the strongest shinobis ever...even madara with all his powers(includin hashi dna) still thinks hashi is capable of beating, which means there's samtin hashi has that we dnt know yet. Am thinking its another kekkei genkai, that when fused with his wood release makes him unstopable. So what could this kekkei genkai be if my guess is right. What KG we know now apart from water and earth can be fused with wood release to make even deadlier. I would say magnetic release...what about you...
