it can go either way. if J-man can make contact with oro at just the right time, he can turn him into a frog or he do the reverse transport thing he did to Pein's dogs to trap him in the Mountain Frogs stomach. If not, Oro takes this
I say J-man takes this.
And take Edo tensei out of the equation. Saying Oro can use Edo Tensei in a fight it's just like having J-Man already in SM and with the 2 frogs already merged with him.
The is no way Oro can perform the Edo tensei summon (whole process) in the middle of the battle.
