you go out, and get a brain
level 100 i am shaqib and i beat heartgold, dimond, platinum, black, white, all of them actually .
All you need to do is the square on your left press it and the box in the bottom to your right press it and thats all you need to do.
You can not your Pokemon all need to be lvl100.
All you need to do is beat the Industrial Castle level. Make sure you have a sandwich on you to open the door at the beginning of the level.
what you need to do raise your pokemons level high enough that you can beat all of them hope i helped from Fire King
The Sword of Awe Is legendary You Need To be Level 35 And You Have To Beat All Quests And Find It.....
you only need dialga in your team but you can if you want when i beat the elite four i had a alakazam staraptor empoleon dialga gengar and rapidash and i beat it in no time at all You don't have to have a dialga in your team. you can go and beat the elite four with no legendary Pokemon at all. i went and beat them without a legendary easily. but i had a level 70 or higher fearow. you don't need one of those either.
my suggestion would be to first of all get all your pokemons to level 55 to 60 then you will have a much better chance to beat the Pokemon league. you will also need lots of fullrestores, revives, etc. i beat the Pokemon league with Garchomp level 56 ( now level 66) Flareon level 60 ( now level 68) Empoleon level 59 ( now level 67) Staraptor level 55 (now level 57) Torterra level 85 (now level 90) Gengar level 60 (now level 68)
You beat all the levels find all the artifacts and minikits and you need to get true adventurer in every level. Buy everything. Also beat the bonus levels. Find the hidden Star Wars Characters.
This can be really tricky buy you have to beat each facility 3 times in a row to meet the frontier brain then beat them to receive the symbol you must do that again to get the gold symbol you must do that for each facility now that can be really hard, fustrating and stressful usually the easy way out is to use legendaries that can enter the facilities however in the battle factory you must choose registered Pokemon choose level 50 for this its easier.
To get super you have to beat all Sonics. (mabey all three of them I only beat two of them im near the end on sonics) You need to get all gold medals for each level
to beat all of the levels
