Kyogre with Thunder. 8)
It'd be awesome to see the combo mentioned above in a Nintendo-event battle.. The Spore>Splash thing... Just taunting your opponent. xD
Well, Suicune's my favorite, but it's hard to find a good one.
However, my Jolteon is amazing. Has a 31 special attack IV, 30 in speed, and timid nature. >w<
And fully EV-trained in both.
