Nidoking

Nidoking finds great strength in his Dream World ability, Sheer Force, which not only boosts the power of moves that have secondary effects, but also negates recoil damage from Life Orb when said moves are used. Base 85 Speed isn't the greatest for a sweeper, but with enough investment, it suffices for Nidoking's purposes. To add to this, Nidoking has an amazing special movepool, which includes powerful moves such as Thunderbolt and Ice Beam; one can even use Nidoking on a weather team in order to use moves such as Blizzard and Thunder. However, Nidoking is fairly frail, and will fold to nearly any attack that comes its way. This is a huge drawback of using Nidoking, but if you can work around its issues, you will clearly see how much of a monster he can be for your opponent.
