there is no level for onix to evolve it will evolve if u trade it to another game make sure it holds a metal coat or it will not evolve
sorry doesn't evolve in leaf green
Onix does not evolve at any lvl. You have to have it hold metal coat and then trade it. Then you will have steelix. Same goes for syther to evolve to sizzor.
Onix does not evolve by level. It can evolve by being traded while holding metal coat.
Onix can only evolve through trading it with metal coat on at any level.
Onix does not evolve by level, it evolves into Steelix by trade whilst holding a metal coat.
a stone onix will evolve into a stone steelixs?
By trading it while holding the item Metal Coat.
In Pokemon, Onix does not evolve at a specific level. The only way that Onix can evolve into Steelix is by trading it to someone while it is holding a metal coat.
You can't. You have to trade it from a FireRed/LeafGreen game. To get it on FireRed/LeafGreen you have to evolve Onix with a Metal Coat.
