Nagato is supposed to be the strongest Akatsuki. But is this true in an actual battle as this was only hype?
Its Tobi before he got nagatos rinnegan. Gedo Mazo is restricted. (actually bot could still control, madara said obito can without rinnegan as he is uchiha with hashiramas cells)
Tobi has his Kamui, he has a second Sharingan implanted (like against Konan), means his Sharingan has 2 x ten minutes of izanagi, the first one will be used with the fodder sharingan and the second if needed with the kamui eye.
+ he has the Uchiha fan and can shoot various weapons out of his eyes (hug kunais, shuriken, rods, etc.
+ he has all Mokuton techs he has shown so far and the huge Katon.
Pain is at his state in konoha, all 6 paths have their power available.
