Did you deliver the ruby and sapphire yet to celio if not you need to before you can face the elite four.
At indigo plateau she is the weakest elite four
you have to go to one island and go to the volcano-ish place and go to the place the rocket ppls were and she will be there. you have to battle them and she will go back to the indigo plateu hope i helped u! (after u beat da elite 4)
either your confused or way out their shes on island 3 in the berry forest She later appears in the ice cave after you beat the Elite 4 the 1st time
Its impossible basicly....only way to get it is by beating the elite four and trading. hope i helped
The elite four will be in the Pokemon league.
Deliver the ruby and sapphire to Celio if you did that go make sure lorelei is not in icefall cave if she is talk to her then leave and go to the elite four now she should be there but if not this means you have not seen your rival on six island he's in the Pokemon center.
Lots of training :) just redo the elite 4 over and over again it can get monotonous though.
Gary is or what ever you named your rival. He will have the Pokemon that is the strongest against your starter. Hope this helped!
no one can do that
the elite 4 should be on route 22 where the indigo plateau is
yes but only if both games have beat the elite four and have the nationol dex. hope i helped
at Indigo Plateau
