Onix and Scyther.
Onix does not evolve at any level. If traded while holding a Metal Coat in Pokemon Gold or later, it will evolve into Steelix.You can't evolve an Onix by leve.l You have to let Onix hold Metal Coat and trade it, then it will evolve into Steelix.
You evolve rock type Pokemon the way you evolve any other kind of Pokemon, except for ones that need to be traded or need a stone to evolve. If you want a Graveler to evolve, you need to trade it to someone else. And if you want an Onix to evolve, you need to trade it to someone while it is holding a metal coat. There are many other mysterious evolutions but I don't have time to name them all :(
Togetic to Togekiss, Onix to Steelix, Roselia to Roserade.
same lvl. as normally, only you have to go to trainer HQ- my Pokemon and you have to evolve them there
onix doestn't evolve with a stone, you trade it while it is holding a metal coat and it evolves into steelix
he doesnt evolve with a stone you have to give him the metal coat t hold then trade it and it will evolve
you need a stone
Onix > trade w/ Metal Coat > Steelix
These Pokemons evolve when the Shiny Stone is used: Togetic, Roselia, Luxio and onix evolve. Togetic evolves into Togekiss, Roselia evolves into Roserade, and onix evolves into steelix. Also, in Pokemon Black you can evolve Minnicino.
A metal coat makes an Onix evolve into a Steelix.
Onix doesn't evolve from anything. It evolves into Steelix, but Onix is the base pokemon for that evolution chain. :)
To evolve onix you must give it a metal coat then trade it and it will evolve
Trade Onix with the steel coat item to evolve it.
In order to evolve Onix in Pokemon Crater you must beat Cynthia. After beating Cynthia she will give you the mental coat to evolve Onix.
In Pokemon Yellow Onix does not evolve, it is a one stage Pokemon.
You can't train it to evolve. For an Onix to evolve into Steelix it must be traded while holding Metal Coat.
