A fight between the leader of the akatsuki and the guy who thinks he’s the leader of the akatsuki. Tobi’s been pulling his strings the whole time. Pain is strong enough that he was able to destroy the hidden leaf village but Tobi could do it too. They are both super strong and sharingan may bot work because Pain has rinnegan. Tobi would have to beat him with ninjutsu. I think he could. Tobi wins.
