Does he have another part to play late in the game? I've beaten the Elite Four 2 times and I have the Kanto Pokedex, so I was wondering if Giovanni would like show up and say that he's your father or something?
I am sharing (sort of) this account with my younger brother.
Somehow we both got the same first shiny, no hacking, just dumb luck.
Games between us:
Sister: Fire Red, Ruby, Emerald, Diamond
Brother: Blue, Leaf Green, Sapphire, Pearl, Red Rescue Team
