The whole NINTENDO company made emerald, I don't think there was a single person who thought of the idea.
Lucario as well as other 4th generation Pokemon were not created in any generation Pokemon game before it meaning they don't exist in Pokemon emerald or anything before Pokemon emerald.
No, Shinx was created for Pokemon pearl, diamond, and platinum. It doesnt exist in emerald.
No. Pipplup wasn't even created until a later pokemon generation.
there is no saffron city in Pokemon emerald, and there is no "Pokemon bluesea" but you can catch both Groudon and Kyrouge in emerald... blue sea is a fake created by some guy who needed some money.
its not an emerald its RAYQUAZA the main legendary Pokemon in Pokemon emerald.
I don't Know if your being serious but regigigas is a Pokemon created for Pokemon pearl and diamond.
Electivire is a 4th generation Pokemon meaning it was created after the GBA Pokemon games so that means its not obtainable in any GBA game including emerald.
You cannot get a Yanma in Pokemon Emerald, as only Hoenn Region Pokemon can be found in Pokemon Emerald.
There is no PalPark in Pokemon Emerald.
