You should go to Dewford city's cave and catch an Aron and level it up a little.
No, Nuzleaf was introduced in Hoenn.
in Pokemon emerald, Sapphire, and ruby, you can catch a seedot right after you leave oldale town. then give it an exp. share. go beat the elite four a couple of times then it will evolve into a nuzleaf. Then go to mosdeep city and dive for a while and you will find a green shard take it to the island with the house on it and get a leaf stone. give it to your nuzleaf and PRESTO! You now have a shiftry. Shiftry will helf you beat the elite four champion in emerald. But not in Sapphire and ruby. HOPE THIS HELPS! You can catch in ruby and emerald as a nuzleaf.

It is your Starter only in Pokemon Emerald, Ruby & Sapphire Treecko evolves into Grovyle at level 16 Grovyle evolves into Sceptile at level 36
The starter Pokemon for Emerald are Torchic, Mudkip, and Treecko. Their second stages are Combusken, Marshtomp, and Grovyle. Their final evolutions are Blaziken, Swampert, and Sceptile.
You can find Nuzleaf on Route 114, but it's rare. It might be easier just to level up the Seedot you should have traded for in Rustboro City.
