You can't
You either have to trade it over from FireRed or Pokemon XD: Gale of Darkness
you can not catch scyther in Pokemon ruby,emerald or sapphire . you have to trade them from Pokemon fire red or leaf green.
You cannot find a scyther in Pokemon white
Scyther can be found (rarely) on Route 229.
YOU cant actually find a scyther but you can do poketransfer on other Pokemon games like Pokemon heartgold and soulsilver.
outbreak
easy-find someone with it and thn migrate it- find it in the pal park all day scyther is not in Pokemon pearl
You can find Scyther at The place where sydney(elite four) is if you walk around :)
Catch a Scyther. Then get a Metal Coat. Attach that to Scyther and then trade.
There is no Pokemon mansion in sapphire.
He is not in Pokemon: Sapphire. You will not be able to find him. He is in Pokemon: Diamond, Pokemon: Pearl, and Pokemon: Platinum. You will definitely have trouble finding him in Pokemon: Sapphire.
you can't find it in Pokemon sapphire, but you can find it in Pokemon ruby. Hope this helped. :-)
