lmfao! But wait you don't need to be a Saiyan to do to Kamehameha I mean Grampa Gohan, Master Roshi, Krillin, Yamcha ( And I think Tien too ) can do it and they aren't Saiyans. Infact Roshi CREATED the Kamehameha and he's not a Saiyan... As far as we know
DBZ wasn't nearly as good as DB though. I had the DS game, "Origins", and it was just like the manga. With Bulma flashing Roshi and everything XD But they censored the flashing cleverly using the dual-screen.
