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.

An examination of its cells revealed the presence of a gene not found in HORSEA. It became a hot topic.

Gold

Its fin-tips leak poison. Its fins and bones are highly valued as ingredients in herbal medicine.

Silver

Seadra Weakness

Good

Electric 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.

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.

    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.
