You cannot find one in emerald (unless you trade or hack)

no only in leafgreen or firered
you need a metal coat
I am afraid that to get a scyther on Pokemon Emerald, you need to trade it off Pokemon FireRed or XD Gale Of Darkness. You get it in FR in the Safari park, and from Cipher Peon Leden in Citadark Isle.
You cannot find a scyther in Pokemon white
Simply trade a scyther from firered while it holds metal coat to emerald you will receive a Scizor.
No only firered can get scyther you can find it in the safari zone.
you can not catch scyther in Pokemon ruby,emerald or sapphire . you have to trade them from Pokemon fire red or leaf green.
catch scyther in fr lg or in emerald safari post e4 and give metal coat and trade
Trade It From Pokemon Fire Red Or Leaf Green
Scyther can be found (rarely) on Route 229.
If you trade the Pokémon Scyther while it is holding a metal coat then it will evolve into a Scizor.
