Elite 4
any level 100 Pokemon that is a dragon type
I don't know the answer but my best guess is about 30
If if its a lower level like 10-20 you should probably go to the cave on the mountain where you fight team aqua.
At the Pokemon league.
I Find that the best place for older games is Gamers.
the best pokemon to use is mudkip.
Uh, the best and ONLY place to capture Tropius is in Route 119, which is west of Fortree City.
The best starter Pokemon in Emerald/Ruby/Sapphire is Torchic. If you level it up well, it'll sail you through the first 3 gyms with ease.
find a place that has wild Pokemon the same level as it.
The best Pokemon in Pokemon sapphire is Rayquaza.He's somewhere close to pacifidilog town on the right,at a place call Sky pillar.Rayquaza is almost imposible to catch so you must have a master ball to catch him.If you don't have a master ball,oh boy.Imagine how hard is it to catch him.He's at level 70{talk about powerful} P.S:He's extremly strong!
Well that is a hard question. It all depends on the level of your pokemon. To train level 25-30 pokemon the best place is Desert Resort. Another place that is good is Cold Storage.
About levels 70-75. It's best if you give it an EXP. share, rare candies, and a Macho Brace. The Elite Four has its pokemon at an average of level 50, so at level 100 it's too easy.
