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.

Seadra Weakness

Avg

Electric and Grass-type moves hit Seadra for super-effective damage. Its Water typing keeps the defensive matchups simple. Seadra's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Start with flexible EVs EVs. A nature nature gives Seadra the right balanced lean, an item adds extra utility, and an ability works in the background. Surf is the main damage option.

Without TMs, Seadra's movepool is bare bones. With them, you get Normal and Ice coverage on top of Hydro Pump and Surf for STAB. The natural kit handles basics, but TMs are doing the real work.

    or evolve from Horsea (Step 1)

  • 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.

  • Watch for Raikou (Electric) and Venusaur (Grass) when using Seadra. They all hit it super-effectively with STAB. Only 2 weaknesses means fewer dedicated counters to worry about.

  • Horsea evolves into Seadra at level 32. Seadra evolves into Kingdra while holding a Dragon Scale. Seadra is a middle-stage evolution in the Horsea line.

  • 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.
