WTH am I reading.....Kabuto?? Really??? Tobi????? A person who got his ass raped by the 4th??? and let's not start with sasuke....he's CLEARLY not on Madara's level....Naruto with Beast and Sage Mode.....maybe....but even that's slim pickings......
I agree maybe with Sasuke not being up to par... But c'mon bruh... U can't possibly tell me you've been currently reading tha manga, and not think Tobi has a legitimate shot of holding his own... Madara's toying with 5 kage's ryt now, yea, but Tobi's not doing so bad, himself, against 2 complete Jinchuriks, an MS, and a master taijutsu user... Back when he faced tha 4th, he didn't have tha Rinnegan, and you can't discount his ability to use tha gedo statu... I mean, that's his thing, at this point, and it has tha power of all 9 bijuus.. Which last i checked, is tha only thing comparable to a perfect Sus'.... Plus, he evade virtually every attack.... Maybe not win, but he would def do better than alright, if not.... And Kabuto, you can't really sleep on either... He has super speed, super sage attacks, can't really hurt him with his Hozuki clan rip, and with that demon mode thing, can use pretty much ne type of tech.... Tha only reason HE lost is cuz of izanami trap... Otherwise, he's out there controlling tha war still...
But yea, everyone matches up differently.. Could go alot of ways advantage-wise...
