the ones you can catch are: groudon, kyogre, rayquaza, regirock, regice, registeel, latios, latias.
The best water Pokemon in Pokemon emerald I believe is Kyogre. kyogre is probably the stongest but i prefer a swampert if you don't like legenderies
Rayquaza, Kyogre, Groudon, latios or latias. Any other legenderies can be traded from other games, Nintendo events, and Colosseum.
yes you need to get the 3 legenderies regice regirock and registeel which can be found on Pokemon emerald ruby and Sapphire
Pretty much all except the legenderies
get all the Pokemon in the emerald dex
emerald has all the Pokemon
200 Pokemon is all the emerald Pokemon to get more beat elite four and get national dex
You cannot get all 202 Pokemon just on emerald because there are Pokemon that are only obtainable in either Sapphire or emerald, but when you trade on emerald it will update your pokedex to national mode.
no you cant find deoxys in sapphire. but u can go to 4shared and download a game called Pokemon sharrowns.in it you can catch most of all legenderies.
In Emerald, Pokemon can be found in Grass, Water, and Caves. There are 385 Pokemon in total.
how to get all the tickets in Pokemon emerald?
No you just need to SEE all the Pokemon in emerald pokedex
