ITEM DEX
Dragon Scale
DE: Drachenhaut · Cost: 2000 ₽
Dragon Scale is an evolution item from Generation 2 with exactly one job: Seadra holds it during a trade and evolves into Kingdra.
What does the item do?
Traded on a Seadra: it evolves into Kingdra. A very tough and inflexible scale. Dragon-type Pokémon may be holding this item when caught.
Which Pokémon does Dragon Scale evolve?
The item must be held during a trade — the evolution triggers on the trade itself.
Seadra plus Dragon Scale plus a trade makes Kingdra. The evolution triggers on the trade and consumes the item. Until Generation 6, Kingdra was the only Pokémon with the Water/Dragon typing and hard to crack defensively, because only Dragon moves hit it super effectively. Generation 6 added the Fairy weakness. In Legends: Arceus you use the scale directly, no trade needed.
Our Kanto dataset (FireRed/LeafGreen) has no recorded location for Dragon Scale. In FireRed/LeafGreen the scale lies on the Water Path in the Sevii Islands (Surf required) and is also a Trainer Tower prize. Neither place is on our Kanto map, so no location is listed above. Wild Horsea only carry it from Generation 4 onward, not here.
One job, but a good one. Kingdra is a strong pick in almost every game it appears in, with good bulk and few weaknesses. The path there costs a trade partner. Without a Seadra on the team, the scale is pure inventory.
