All are at full chakra and fully healed. Both can use all the techniques they have. No Edo Tensei for Orochimaru though, because they got sealed. Kakashi does have MS and Kisame does have Samehada. They are half on, half off a lake, with Kakashi and Kisame standing on the lake, and Orochimaru standing on the ground part. So mid to long range. What would happen?
