Pikachu

I choose you Pikachu! As Ash's first Pokemon, Pikachu makes a shocking impression on the Pokemon master-to-be. This lovable and cuddly Pokemon may look innocent, but threaten its owner and you'll get a jolt of 10,000 volts of thunder shock protection. When several of these Pokemon gather together, their electricity can build and cause lightning storms.
