yes using a action replay for your DS but it would more then likely mes your game up so i dont encourage that.
there is no way unless you use an action replay or a Nintendo event.
Battle the Elete Four over and over again and eventually your Pokémon will get to lv. 100.
get all of your pokemon to lv 100
there is no easy way to get to level 100 just stock up on joy seeds until you have enough for all your pokemon or just the pokemon you want to be at level 100.
no there is no possible way
the fastest way to get Pokemon to level 100 is to keep battleing the elite 4 and chapion with wat Eva Pokemon u want at level 100
There are literally hundreds of ways to get a level 100 pokemon. One way is by trading with a friend or through the GTS. Another way is to just train hard.
You can't get your Pokemon over level 100. There is one way: using a Game Boy Advance Cheat cartridge - you may migrate Pokemon at any level you like. Simply buy the cheat system/cartridge and get the cheats online or in cheat books, then migrate any Pokemon on any level. 'Migrate' means 'send Pokemon', but you can only migrate the Pokemon you have on your GBA games (such as Emerald, Leaf Green and Fire Red). With a cheat system/cartridge, however, you can have the migrated Pokemon on any level you would like. You could only get Pokemon over level 100 in the first generation Pokemon games (Red and Blue). Through the MissingNo. glitch, if you continued to Surf the side of Cinnabar, you had the chance of encountering a Pokemon (mostly Snorlax) which was over level 100. Unfortunately, if that Pokemon was levelled up, it would go back to being on level 100. This glitch was fixed and therefore does not apply to the later generations of Pokemon games (from Gold and Silver onwards). So these days, it is impossible for a normal Pokemon to be over level 100.
I dont think so.
yes
training it.
you can give them a lot of rare candies
