unfortunately, you cant. you have to trade it from leafgreen or firered. hope i helped :)
there are no steelix in saphire,emerald and ruby version. hope my answer can help you! if you want to get a steelix you have to give an onix a "steel coat" and via trade it. after you trade it, it will automatically evolve.
You can't you will have to trade from leaf green or fire red
Onix does not have a pre-evolution form currently as of Pokemon Omega Ruby and Alpha Sapphire and has not been announced for the Pokemon Sun and Moon games.
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.
Onix cannot be found for capture in Pokémon Ruby you would have to arrange a trade with another player or you would have to catch Onix in either Pokémon FireRed or Pokémon LeafGreen (in Pokémon FireRed and Pokémon LeafGreen they can be found in the Rock Tunnel, Victory Road and the Seavault Canyon) and then you would have to trade it from either Pokémon FireRed or Pokémon LeafGreen over to Pokémon Ruby.

If you mean,, what onix evolves into,, it's steelix,, but the is no Pokemon that evolves into onix
onix evole from gedude
onix is the strongest
Onix doesn't evolve from anything. It evolves into Steelix, but Onix is the base pokemon for that evolution chain. :)
Onix evolves into Steelix when you trade Onix while holding a metal coat.
Here is a battle of Raiku and Onix. Raiku uses shockwave on Onix, paralyzing it. Then Raiku uses thunderbolt on Onix causing little damage on it. Raiku uses thunderstrike on Onix, causing little damage. Onix uses earthquake, killing Raiku.
