Seaport City

The move involves two turns: during the first turn, the user dives underwater, becoming semi-invulnerable and protected from most moves. In the second turn, the user resurfaces to deal damage. While submerged, Surf and Whirlpool can hit the user, dealing double damage in most generations, except for Generation IV, where the move's power is doubled instead. Being targeted by Lock-On or Mind Reader before diving or having No Guard by either the attacker or the submerged Pokémon can also allow attacks to hit the submerged user. Weather conditions like Sandstorm, hail, and Shadow Sky do not damage the submerged Pokémon during the semi-invulnerable turn.
