orochimaru was surpassed as was stated multiple times by kabuto. and no one would know oros full powers better than the guy healing his every wound and watching his battles.
kabuto has the ability to control anything dead. so he would take control over kusanagi sword and cut oro up with it. before orochimaru can body shed, kabuto moves in and bisects orochimaru. since oro would just rebuild himself, kabuto then puts him in demonic flute. oro is now paralysed and defenceless.
kabuto is faar faster, more effective in defence, doesnt lose stamina or SM, isnt affected by orochimaru genjutsu if he has it, great waterfall tech would wash back ten thousand snakes.
suigetsus ability makes most of orochimarus offence worthless.
Oro takes it. kabuto wouldn't have DSM without Oro
whats orochimaru's counter for the SM techniques?
Also in tht true form he releases paralyzing poisen witch I Dnt see how kabuto would escape
why would he resort to true form when not changing bodies?
Cant oro just take his chakra back from kabuto like he did recently then fights over kabuto sucks
how does he do that while kabuto is moving about nimbly spamming high level attacks at him?
Oro has to many jutsu up his sleeve
and kabuto probably can perform all of them if he wanted. kabuto seems smarter to me and more effective in durability and stamina.
Orochimaru wins kabuto doesn't have anything to put him down
demon flute genjutsu works as well as oro's poison blood.
