erm......you battle them.
Bet the elite 4 and champion.
i bet them and Cynthia 5 times in Pokemon platinum.
No.You have to get Pokemon ranger and transfer to your game.
nothing new
Yes u have to beat the elite four then u need to transfer a regihigass(spelled wrong) to Pokemon platinum to get regihigass u need the other regis then migrate them to pearl or diamond the go the the snowpoimt temple PS. It is not worth the time really so I would just wait for a toysrus event
first of all you have needed to bet the elite four then it depends on your starter if you choose bulbasoar you will get entia if you choose charmander you will get succiune and if you choose squatel you will get the electric one sorry I forgot its name. After you bet the elite four your Pokemon will by in the wild the easyiest way to atch it is with a master ball or wubbfett.
bet the elite 5 as many times as you can
no your not i bet them with a lvl 61 infernape and a lvl 40 bird Pokemon
oh yes i bet the hole elite four with one hitter quiters with flamthrower
Of course not! They aren't called the "Elite" Four for nothing! If you fail, try changing around and leveling up your team. Practice makes perfect!
first you bet the elite 4 and then go to ciolol and then you need to find the gems
as far as i know, u can get mewtwo(cerulean cave, after beating the elite four) and entei(if starter is bulbasaur), suicune(if starter is charmander), or raikou(if starter is squirtle). entei, suicune, or raikou are found wild in LG and FR after beating the elite four.( ur best bet is to search on route 1.)
