Water and Grass attacks are super effective against Onix.
Water Pokemon. You can also use rock Pokemon such as geodude or onix. Do not use grass or steel Pokemon these types are week against fire.
Ground type Pokemon like Sanshrew and Onix (Onix is half rock, half ground, like a Geodude)
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 :)

Ground works best against electiricity do you should use Pokemon like onix, geodude and so on to beat them

Well, i dont know how you are going to recruit it with a grass pokemon, because you will most likely lose. Try a water, electric, or for a super-super effective pokemon, try a rock type, like graveler or onix. For more types, try www.serebii.net. Good Luck!

Onix is in Pewter City where Brock is.
Onix is a Rock/Ground type Pokemon.
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.
This is very unlikely, but possible. Bruno has two Onixs that have super effective moves against Zapdos, and electic-type moves don't effect Onix, so that might be a problem.
Please see the related link for info on the pokemon, Onix
