Galvantula

Oh, how I enjoy this new pokemon brought by the 5th generation. With this currently running on my team I can very well say, that it is a great pokemon. I don't want to run on about it, but it is quite a good counter to the current UU metagame, with fast speed, excellent special attack, and the ability compoundeyes you are sure to hurt anything that is on the field.
