You cant skip the league, if you want to end the game. You have to beat the league, in order to get the national pokedex. Then you can start trading, to collect all 493 pokemon!
hope I could help
I'm sorry mat but you just can't unless you use cheats but I completely object to them
NO..veronica

She stays in the Pokemon League.

Its the same as Pokemon Diamond,After you watch or skip the credits,youll go back to your house.go downstairs and your mom will say something about your rival going on a boat in snowpiont city.go there and youll be taken to the battle area.
There is no way you have to compleate the pokedex but most of it is at the gyms.
uh, no, you have to play it
the best Pokemon for the Pokemon league is definetly latios
I beat the league on Pokemon Diamond version, and there was no cave involved, if that's what you were asking.
Scrub them with your stylus
Buy it at the poKemon league
