Damn people it was said that the first's technique just like the third Kazekage's technique were techniques only they, the individuals, could perform not any bloodline limits. As for bloodline limits I haven't seen any skip a generation, the point of the bloodline limit is that everyone who has that blood can do it. The only exception we've seen is the sharingan, although every Uchiha has that potential, they aren't just born with the ability they have to awaken it. Please no one try to make the stupid argument that maybe Tsunade has to awaken her abilities, please.
