NO......The right analog stick is also known as R3. I am speaking of difficulty settings (Options).
Very Hard
Z
Z2
Z3
Basically, Beat Dragon Universe (with anyone) on "Very Hard" once, and it unlocks "Z" mode. Beat D.U. on "Z" mode once, and it unlocks "Z2".....and so on. When you beat Dragon Universe on "Z3",...you get a capsule labeled "Strongest of the Universe Trophy". It doesn't "do" anything,....but you need it for a 100% capsule count.
Death is but a door, Time is just a window,...I'll be Back!!!!!
