If u don't get it, Goku and Gohan from DBZ do Fatherson Kamehameha, and Minato and Naruto from "Naruto" do the Father-Son Rasenshuriken. And i know that minato only knows the original rasengan, but still, think of the epicness. I don't even know who might win but im betting a Father-son kamehameha will be better huh?
