kabuto loses. How? I don't know yet, but he loses. He can't win, neither can minato. But we've seen kabuto's entire arsenal.
Sound gen only paralyses. You can still see, think, etc. Seal-less jutsu (Shadows, FTG) would still work
White Rage - Doesn't stop you from using jutsu, just causes intense pain so makes it unlike you can.
Muki tensei has no place or use in any where but i cave for this battle.
All the sound 4 abilities can be FTG dodged.
A few boss toads handle manda 2 and keep him out of the fight.
Kabuto has to activate hydrification for it to work. It's not always active and he can sustain damage when it's not even though he can heal.
The only thing that draws the fight on his healing/oral rebirth. Without that, or with a way around that, kabuto is easily brought down
Kabuto isn't a big main villain. His only role was to use a massive edo army. On his own he's no big threat or he'd have actually been able to at least scratch sasuke, but i expect a wave of flame responses becauses NB seems to be in love with Kabuto
