This is a page dedicated to all the water Pokemon out there. It's also dedicated to Misty lovers everywhere. All the water Pokemon I know about are listed above. In the beginning of the Pokemon Gameboy game, you can start out with a Squirtle if you want to. You can easily beat the rock and ground Pokemon that live in Mt. Moon. And Brock will be a little easier to beat. For your battle with Misty however, I suggest you get another Pokemon to fight against her. Water against water isn't very effective. Of course this is all up to you. In your final line up you should include a water Pokemon. You don't really need one in when battling the Elite Four, but when battling against friends you never know when someone will whip out a fire Pokemon. A good water Pokemon is Blastoise.
