Onyx can only be evolved by giving it a Metal Coat and trading it with someone.

Onix evolves while being traded to someone else, holding a Metal Coat.
Onyx doesn't evolve by level you trade it holding a steal coat!!!!! ONYX ONYX ONYX
sorry to break it to you there is no steel stone. if youre trying to evolve onyx into a steelix or a scyther into a scizor then you have to trade them while they're holding a metal coat. dont ask me where to get a metal coat. i forgot.
The Metal Coat is used for giving to your Pokemon (such as either Onyx or Scyther) and trading it (it would probably be best to trade with a friend though); because as you probably already know some Pokemon evolve by trading or giving them items then trading them.
Yes, Onix does evolve into another Pokémon. Onix will evolve into Steelix after being traded while holding a Metal Coat.
you need steel coat i believe
