Who was said to be the greatest shinobi ever teams up with the most destructive being in the Narutoverse in order to take down Akatsuki. No prep, fight takes place in a gargantuan field in a thunderstorm. We will include Orochimaru and Sasori. No Shiki Fuujin, Yondaime can't summon the boss frog. Edit: The battle begins with Yondaime on the Kyuubi's back, while Akatsuki are all spread out on the field, side by side. Fight to the death.
