Re: The 4th MS jutsu?
It's better than my explanation as to why Madara still lives.lol I said since the sharingan and the Rinnegan have at least some characteristics in common, one being transmigration (which allowed Pain to control six bodies with his own persona being spreaded through them).
Well I said the sharingan has that final characteristic however, it is only awakened once the secret is discovered (Madara discovered the secret by mastering all secrets of the sharingan). Well I say Madara had been transmigtating through the Uchiha population, always keeping an eye on Konoha and the Uchiha clan for generations.lol
I suppose your idea makes more sense.
The Specialist, forever
