i think oro has got this one
What makes you say that?
orochimaru full health was able to take on hiruzen to the point where he had to kill himself in order to beat oro and even then oro only lost his ability to perform handsigns, a full health oro i reckon would beat konan, im not underestimating her im sure she would give oro a run for his money but i just dnt know enough about konan to make a fair judgement on it.
