no. the champion is too tough. maybe if you had a lv.100 torterra and a palkia. i beat the champion with torterra and palkia.
get them to level 60 or above, get a fire type too, they rule at smashing the elite 4. i defeated them just usin my level 63 charizard and level 57 wartortle. :D
After you defeat the elite four on Pokemon sapphire you complete the pokedex and make all your Pokemon level 100.
starter lv.60
I used these: Tentacruel, Lucario, Torterra, Staraptor, Luxray and Infernape. I recommend getting all of your Pokemon into a high level, like in the 55-70s. Also, make the types a variety and also study the elite 4's Pokemon. Also practice. Get many strategies.
You either start with turtwig and level it up to a level 32 (past grottle) and then you get a torterra or you can see it from a trainer in victory road (path to elite four cave like)!
Maybe you have to have a great move on your pokemon
you defeat the elite four by training a particular Pokemon and getting it to a high level(e.g. lv64) you also give it the best four moves that you have. try to give it moves that have a lot of pp though because you need to defeat the elite four who have a lot of Pokemon!
Infernape LV61 Dialga LV66 Torterra LV59 Riolu LV59 Luxray LV61 Snover LV58
I need to beat the elite four but i cant even defeat the first bug pokemon. i promise i'd give it back.... but i dont really have any way of securing it cause i have nothing cool besides my level 64 torterra.... so if anyone is nice enough i hope.....
He evolves at level 32 in Pokemon platinum
Train it in the elite 4!!!!
train your pokemon up to level 80,90, or 100 and teach it TMs and HMs
