well im just thinking that healing a single wound no mather what caused it, is no reason to be called a good medical ninja but thats stil my opinion :D
yeah but even sakura is able to heal single wounds like any other basic medic ninja so thats nothing special
the amazing thing about kabuto was his instant selfheal, when the 3 sannin were fighting for example. after naruto hit him with rasengan his wound just disappeared:D
tsunade, kabuto was only showed healing himself like shodaime
but like i said in another thread, tsunade healed the whole hidden lead with her snail summoned
i dont think kabuto or hashirama were able to heal the wounds of others on such an amazing lvl
im not surprised i knew that madara lost against shodaime a long time ago
BUT any shinobi that defeated uchiha madara HAD to be godlike cause madara is the big boss :D
