you need to have at least 999 rare candies (this works for all games).
train, or rare candy
Have level 100 pokemon
bring any level 100 Pokemon from diamond version or train a Pokemon to level 100 and go defeat them.
Like all other pokwmon games, the max level you can train a Pokemon to is 100
train in wild Pokemon battles through out the game
No,that is not actually possible.
battle with level 100 pokemon
you have to use a level 100 if you want to be SURE to beat Red
you can get to level 100 but no higher
There isn't someone like that in the game. But your stronger rival is Red, whose Pokemon are in level 80 or more.
yeah!! it is so hard to get Pokemon like that at level 100 i think that is awesome!! i have only one level 100, that is a feraligatr you have a good party let me tell you that
all I can really say is that use an action replay and give it as many as it takes to get to level 100. or you can get a lvl 100 starter if you trade with someone who has or you level up your starter like crazy.
