In Pokemon Yellow Onix does not evolve, it is a one stage Pokemon.
If you mean,, what onix evolves into,, it's steelix,, but the is no Pokemon that evolves into onix
Unfortunately, you can't get an Onix in Pokemon Emerald. To have your own Onix, you need to trade it from FireRed or LeafGreen. Hope I helped :)
You can only get an "onix" in Pokemon sapphire if you have a Pokemon version that has an onix then use a linking cable with other GBA to trade it and then you'll have an onix but "onix's" data can't be stored in your pokedex.NOTE:You can only trade with a Pokemon version that have the same region as your Sapphire has;HOENN REGION.
Please see the related link for info on the pokemon, Onix

There is no such thing as a Crystal Onix in the Pokemon games series. It was only in the Pokemon anime.
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.
