If you speak to Scott (the manager of the Battle Frontier) he will reward you with exclusive Berries.
Talk to Scott to receive a special berry.
You are a Pokemon master.
Nothing exciting happens there on emerald.
You should have completed the nat dex. This gives you the chance to get Chicorita, cyndaquil, or totadile. You can only get one. MAKE A GOOD CHOICE :)
You get the chance to encounter Kyogre and Groudon, also the battle frontier is unlocked for you and each of the Pokemon that have been in your party after defeating the elite four will gain a ribbon for defeating the champion. Hope this helped :)
You don't get it normally. It happens on account of a glitch inside Pokemon Emerald.
I think she laughs at you.
U cant it only happens in emerald using the emerald cloning glitch.
Nothing happens. Get over it.
You can't make it happen, it just happens. :P

You get a diploma, a hall of fame, fronteir symbols and special berries from Scott plus prof birch will let you have a johto starter.
