At the Fight Area in front of the Battle Park entrance thing
nothing he goes to stark mountain and he's only at the fight area on the weekends
nothing happens just he is gone until Saturday and Sunday you battle him only on the weekends
If by strong you mean higher level, the stronger trainer is your rival, which you can battle at the weekends at the Fight Area.
No. You can only fight him on the weekends. Also, some action replay codes you use for Pokemon pearl can have side effects like deleting items that you get that you didn't have before and sometimes, battling you rival everyday. This happened to me and his location changes to the place where you got off the boat in the Fight Area.
You just have to go there, and in front of the entrance of Battle Park/Tower, he will be standing. BUT he is only there on Weekends. Also, he gets stronger each time you BEAT him.
Yes, when you go on the boat at Snowpoint City, you'll find your rival in Fight Area who will battle you on the weekends. In Pokemon Platinum, you can face him again in the Survival Area instead.
Nothing happens, really. You will receive $6400 but $12800 if your Pokemon is holding Luck Incense or Amulet Coin. When u beat him he'll stay but will apear only on weekends, so be in for a tough fight! :P
Well, for all I know you fight your rival about 12 times and then on certain days, you get to fight him at the Pokemon League.
yes i saw him on a sat.
About 10 times then you can fight your rival at certain days at the Pokemon League.
whatever you want really...
you fight your rival
