Horsea

Horsea is a premier special sweeper on Rain Dance teams. Swift Swim, coupled with base 60 Speed, allows Horsea to reach 32 Speed in the rain. It has the second highest Special Attack among all Pokemon with Swift Swim. Thanks to its high Speed stat, Horsea is a good option to use over Mantyke. Horsea also has higher Defense and Special Attack than Mantyke. Horsea's base 70 Special Attack allows it to reach 17 Special Attack with maximum EV investment and a Modest nature. It has a good base 70 Defense stat, but a poor base 25 Special Defense stat, which means Horsea can only take physical hits effectively.
