Seaking (ex1-21) is a Water-type Stage 1 Pokémon from the Ruby & Sapphire expansion. It has two attacks: Water Arrow, which deals 20 damage to any one of the opponent's Pokémon, and Fast Stream, which deals 30 damage and moves an Energy from the Defending Pokémon to the other Defending Pokémon. With Lightning weakness and zero retreat cost, it can be used as a mid-stage attacker or to manipulate opponent Energy placement in multi-Active formats.
