yes
you have to go to seven island after defeating the ellite 4. on 7 island you go straight up and you will see a body of water surf and keep going straight and you are in a building. go straight.
YES.
if you cach an onix there is a posibility that it could be holding a metal coat
sorry, you can not buy a metal coat on fire red. trust me, i tried.
You have to give it a metal coat and then trade it.
If you are referring to the original Pokemon Red for the GameBoy, then you can't get a metal coat due to the fact that Steelix or Scizor were not Pokemon back then. If you were referring to FireRed, I have no idea.
It evolves two pokemon: Onix and Scyther. Have each hold the Metal Coat then trade them to a friend take them back and you will get a Steelix and Scizor.
Scizor can be obtained by trading a Scyther while it holds the item Metal Coat.
trade from firered and on firered you have to evolve scyther (which you can catch in the Safari Zone) by trading it with a metal coat
Don't need to because you can get more from leafgreen or Pokemon colosseum and Pokemon xd gale of darkness.
Trade Onix with a metal coat to someone eles then it will evolve thne ask for it back ,and you have a new Pokemon
Scyther does not evolve by leveling up in firered, It evolves by being traded while holding the metal coat.
i dont know if you can get a metal coat...if you get one you can trade an onix with one and get steelix
