in emerald it is sidney then forgot then glacia then forgot then the champion is wallace
You have to catch one in emerald after the elite four in Pokemon emerald and you have to trade the other lati from Pokemon sapphire or ruby.
In emerald, you go in a special cave after beating the elite four, but for sapphire you need to trade from FR, LG, or emerald.
same as emerald go to sky pillar and get after elite 4 or before elite 4.
in Pokemon emerald simply beat the elite 4 then you will be invited to the battle frontere then find it but it is not in sapphire or ruby sorry bout dat
The elite four will open and they will be stronger and you can now trade with ruby, sapphire and emerald.
First you have to migrate the Pokemon to diamond(have to beat elite 4) Then you trade the Pokemon to Pokemon white
Ruby/Sapphire/Leaf Green/Fire Red/and i think Emerald. if not, trade from emerald to Ruby/Sapphire, and from ruby/sapphire to leaf green. You need to have the Sapphire and Ruby before you trade. you get these after the elite four.
You have to beat all gym leaders and the Elite 4 and Champion.
It depends on the way you see it. In terms of Pokemon you can catch, emerald is just like a mix of sapphire and ruby (not combine because some Pokemon like Roselia cannot be caught in emerald that can easily be caught in sapphire) with a little of leafgreen and firegreen (after elite four you can get shuckle, mareep .etc in safari zone)
You can trade from Sapphire anytime. However if you are trading to or from Leaf Green, you have to have beaten the Elite Four first, before you can trade with Ruby, Sapphire, or Emerald.
either you get Pokemon emerald or Sapphire, and if you want them on diamond or pearl you have to beat the elite four and then migrate.
Emerald: He is the champion of the Elite Four; Juan is the Sootopolis gym leader. Sapphire/Ruby: He is the gym leader of Sootopolis.
