Can you not read? But anyways mobility issues aside, Nagato is a beast so are his six paths. I would see Obito having trouble getting rid of him especially with Konan.
He would obviously pull an Obito and fight his maker.
Unfortunately Obito would ms curb stomp the sh*t out of Nagato, because Nagato isn't like konan who would plan a full proof senerio on his ms technique.
what was obito planning on using nagato for anyways? nagato didnt know about IT. he had another idea. obviously zetsu wouldnt be happy at the time. smells like plot. im sure obito had some kind of plan b.
