While most trainers evolve Seadra into Kingdra immediately, the unevolved form has a niche with Eviolite boosting its defenses. Only weak to Electric and Grass. Sits at a decent but contested Speed tier. Known as the Dragon Pokemon.
Seadra's built around special offense. Defense leads the charge, Sp. Def pays for it. Moderately hard to find, worth 2 Defense and Sp. Atk EVs. Follows a medium-fast 1M XP curve.
The male raises the young. If it is approached, it uses its toxic spikes to fend off the intruder.
Seadra Weakness
GoodElectric and Grass-type moves hit Seadra for super-effective damage. It resists 4 types, giving it decent defensive coverage. Seadra's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
- Special stat split into Sp.Atk and Sp.Def
Seadra is partway through a three-stage line between Horsea and Kingdra. The chain involves a trade, so it's not a straightforward grind. So far, HP got the biggest boost (+25 from Horsea). The final form adds another 100 stats on top.
How to Evolve
Breed with Seadra to get Horsea eggs easily using 13 partners from the Dragon and Water1 egg groups. Notable egg moves include Aurora Beam, Disable, Dragon Rage and 3 more.
Start with flexible EVs EVs. A nature nature gives Seadra the right balanced lean, Quickclaw adds extra utility, and an ability works in the background. Surf is the main damage option.

Without breeding, Seadra misses out on Aurora Beam and Disable. That's 6 egg moves adding depth that the base kit lacks. STAB comes from Hydro Pump and Surf, with Dragon and Ice coverage rounding things out.

Seadra isn't fully evolved, so it's not built for competitive play. You'll want to evolve it into Kingdra to unlock its full potential. At 440 BST, it's a stepping stone rather than a team anchor.
Seadra fills the balanced role. It's a special attacker with base 95 Sp. Atk. Base 85 Speed is workable — faster than some, slower than many.
Seadra appears in 20 games, including Yellow, Red & Blue, and Gold & Silver.
Seadra has been part of the series since Red & Blue, appearing in 20 titles across all 9 generations. As a Gen 1 original, it's one of the most consistently available Pokemon in the franchise.
