However as always a chapter where a strong character shows off his abilities and people think he is an unbeatable god. The same thing happened when the Raikage battled Sasuke and all the Raikage fandom went on in different forums here and there.
Hes one of the strongest shinobi in the narutoverse no doubt but his abilities have limits. In an example because has to use his kunai to warp someone can simply use another kunai to deflect them before they get close and keep him at bay.
Aside from which Kishi has already officially responded to the question of if Minato was the strongest shinobi of all time and he said he was tied with the 3rd as far as dead shinobi go but there are a few people alive stronger than he is.
The real scary thought would be if Minato and Itachi teamed up now that would be a tough pair to beat.
