Yes they were. You could get them in Pokemon Emerald from Pokemon Colleseum. And I meant the best Pokemon you could get in the GBA generation games. Not the best Pokemon FROM the GBA games. You must of intreperted it wrong.
Well, I think the best Pokemon from the GBA generation are Treecko, Minun, and Zigzagoon.
Also, please feed my Pokeball a rare candy. It is only lvl 2. Plz feed it!!!!!!!!
