Pikachu, mainly. I mean, I love Pikachu, but like everyone has said, when you think Pokemon, the first image that comes to mind is Pikachu going Pikaaa! He is (or should be..) Pokemons mascot. He had a whole game to himself (XD), he is Ash's partner in crime, and hes so cuuuute. Another I would say is Eevee and his line of evolutions. Sure, they are cute and all.. But seriously, I have never used one in my entire life. Dont really plan on it anyway, since there are much better Pokemon that I like a LOT better that I would rather take up that space in my party. Heck, 120 hours of play time on my SoulSilver and still havent picked up that Eevee from Bill or bob..Whatever his name is XD. Lucario is another one, he looks cool and all... But why did he get a movie to himself?!?!?!?!?!? And also that red Gyarados..Everyone dotes over him >_>.
