There was a similar thread a while back, but that was closed before a decisive outcome was achieved. I invite users to come up with new ideas and interesting versions of this fight.
For your consideration:
1) This is Part 2 Itachi that is not dying.
2) This is alive Hokage Minato.
3) Fair fights, no plot armor and both have their usual apparel.
4) Location: Amegakure
Who would win and how?
