Seadra, the Dragon Pokémon. It is known for its powerful disposition that possesses both strength and speed.
– Ash’s Pokedex
Despite Seadra’s species name as the Dragon Pokemon, it’s not part Dragon until it evolves into Kingdra (which was introduced in Gen II). If a Horsea has the Swift Swim ability, when it evolves into Seadra, its ability changes to Poison Point instead, but will change back to Swift Swim if it evolves into Kingdra. Seadra is the only non-Poison type that can have Poison Point as an ability.
Stat-wise, it has decent Speed, Sp Attack, and Defense, but pretty bad Sp Defense. Though with Gen V’s new held item Eviolite, its defenses can be boosted.
