Kingdra @ Choice Specs
Ability: Swift Swim
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
- Hydro Pump

These Pokemon are the most popular rain abusers in OU, as their Swift Swim ability allows them to outspeed a vast majority of the meta. Swampert can also set up Stealth Rock to damage opposing Pokemon as they switch in.
Greninja-Ash @ Choice Specs
Ability: Battle Bond
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Hydro Pump
- Dark Pulse

Although it doesn’t have any abilities like Swift Swim that boost speed, Ash-Greninja is incredibly fast and powerful, and it is hard to switch in to in rain.

Ability: Regenerator
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Hurricane
- Knock Off
- U-turn
- Defog
Tornadus-T is a great offensive pivot for rain teams because it threatens grass types with unmissable Hurricanes, and can regain health with Regenerator. It also provides Defog support for the team.

Ability: Electric Surge
EVs: 20 HP / 252 SpA / 20 SpD / 216 Spe
Timid Nature

Another viable offensive defog pivot for rain teams, except this time, it has unmissable Thunders. It can check some water types that may abuse your own rain.
