koko with the kabuto thing, thats unless jiraya or tsunade own him in the first 5 seconds... if its a 2v2 with jiraya+tsunade vs kabuto+oro do u really think jiraya couldnt fight oro himself for at least a while while tsunade owns kabuto? or vice versa?

but its hard to say whether it'd be sasori or oro, they both kinda had immortality because oro kept switching bodys and sasori was a puppet...

i'd say oro
