Raikou

Throughout each generation and metagame, Raikou has been a stellar Electric-type that possesses above-average power, excellent Speed, and respectable bulk. The VGC 2012 metagame continues this trend, as Raikou is still more than capable of being a dominant threat. The Crown Raikou event blessed it with new moves such as Weather Ball and Aura Sphere; however, Raikou can only use a Rash nature with these. While this does provide Raikou with extra power, it also prevents Raikou from outspeeding Pokemon with base 100 Speed, as well as Garchomp. On top of this, the drop in Special Defense leaves it more vulnerable to powerful special attacks. Non-event Raikou is viable as well, however, forgoing Weather Ball and Aura Sphere for Speed and bulk. Raikou can be a very effective Pokemon in VGC whichever way it's utilized, and it should never be underestimated.
