go to the pokemon page and click evolve
By leveling It up to level 16
Actually Pokemon Omega Ruby and Alpha Sapphire is not out yet, but I strongly believe Bulbasaur will evolve at level as usual I doubt it would change dramatically.
Goldeen evolves at Level 33 in Ruby, Sapphire, FireRed, LeafGreen, Emerald, Pokemon X and Y and Pokemon Omega Ruby and Alpha Sapphire.
Swablu evolves into Altaria at level 35. Altaria can mega evolve in Pokemon Omega Ruby and Alpha Sapphire when it is holding a Altarianite during a battle.
Kadabra does not evolve by leveling up. You will need to trade it to evolve it into Alakazam. I recommend asking a friend with a copy, either in person or online, to do a trade-back with your Kadabra.
no i don't believe so
It evolves by happiness
all you have to do is fight
no omega is not a real pokemon, but arceus is considerd the omega pokemon.
