Seadra is one of the original water-type Pokémon included in the first generation of the Pokémon games. Seadra’s design is based on a seahorse and has a blue body and wings with pointy tips. Seadra evolves from Horsea. Kingdra is it's third and final form. Kingdra was introduced later in the second generation games. Seadra is one of the few Pokémon that require special conditions before it can grow into its final form. This wikiHow teaches you how to evolve Seadra into Kingdra.

How to Evolve Seadra in Pokémon

In order to evolve Seadra into Kingdra, you must trade Seadra with another player while it's holding a dragon scale. The dragon scale can be found in certain areas depending on what version of the game you're playing. You can find a dragon scale by searching for hidden areas or defeating wild Pokémon in specific areas.

A Dragon Scale is a blue scale-like object that is required to trigger Seadra's evolution process. It can only be found in specific areas inside the game. These special areas vary depending on which version of the game you’re playing. Look for Dragon Scales by searching for hidden areas or defeating wild Pokémon in the following areas:
- Gold, Silver, Crystal, HeartGold, and SoulSilver — Can be obtained inside Mount Mortar. They can also be acquired by defeating wild Horsea, fellow Seadra, Dratini, and Dragonair.
- Ruby, Sapphire, and Emerald — Can be acquired by defeating wild Horsea and Bagon.
- FireRed and LeafGreen — Can be obtained inside the Water Path and Trainer Tower.
- Diamond, Pearl, and Platinum — Can be acquired by defeating wild Horsea and Seadra.
- Black and White — Can be found on Route 13 and 18. They can also be acquired by defeating wild Horsea, fellow Seadra, Kingdra, Dratini, Dragonair, and Dragonite.
- Black 2 and White 2 — Can be found on Victory Road, inside the Antiques Shop on Join Avenue, and inside the Wild Forest. They can also be acquired by defeating wild Horsea, fellow Seadra, Kingdra, Dratini, Dragonair, and Dragonite.
- X and Y — Can be found inside the Terminus Cave. They can also be acquired by defeating wild Horsea, fellow Seadra, Kingdra, Dratini, Dragonair, and Dragonite.
- Sun, Moon, Ultra Sun, and Ultra Moon: Can be acquired in Battle Tree. They can also be acquired by defeating wild Dratini, Dragonair, and Dragonite.

Seadra will only evolve to Kingdra once it's traded to another player. Use the game's trading system to do this. Here's how you can find a Trading Center depending on your game's model:
- For older versions of the game, you can trade Pokémon with other players using the Game Boy’s cable link connection by going inside a Pokémon Center in any town and talking to the receptionist (non-playable character) in charge.
- For newer generations (fourth generation to present), trading Pokémon is done using the Global Trade Stations (GTS). To trade using the GTS, go inside a Pokémon Center in any town, and talk to the receptionist (non-playable character) in charge of the system. You can also use Quick Link to trade Pokemon locally with friends.
- On Pokemon Go, players can trade with registered friends. Regular trades cost both players 100 Stardust. ^{[1]

Trade your Seadra.

1
Ask one of your friends to trade Pokémons with you. Select Seadra from the list and trade it with any Pokémon the other player has or is willing to exchange. Once the other player receives Seadra, its evolution will start and will then change to Kingdra.
- Seadra will only evolve when traded while it’s holding the Dragon Scale. Trading without a Dragon Scale will not evolve Seadra.
- Leveling up and gaining experience will not trigger Seadra's evolution.
2
Trade back your newly evolved Kingdra. Ask the other player to start another trading system so you can have Kingdra back.
- You can choose to skip this step if you prefer not to get your evolved Kingdra back.
