Edo Madara, Obito and Kabuto (with Edos) can defeat Naruto with 100% certainty.
We'll see about that, kishimoto decides these things and I don't believe our main character is anywhere near as weak as you assume, he is testing his enemies now that they have no where to hide and we have yet to see even the beginning of how they're actually going to handle obito/madara and what is the deal with Kabuto?! He's a f'ing chump. Have not seen one thing at all that would be too much for Naruto not to mention he already got his ass handed to him. PLEEEEEEASE stfu about Kabuto being somebody he's a horrible pawn of a poser STILL being used by Orochimaru to accomplish goals that have yet to be seen. I have already told you what happens when the power-hungry fight the power-ful, they lose every time. Watch more animation if you have yet to realize this. Naruto is a champion to adversity, these sad men are all just that, sad men. As of right now they will pull a bunch of stuff out of their asses but in the long run Naruto will prevail, any other assumption is downright retarded. How would he become Hokage if he can't even beat Tobi, much less Madara?
