Pokémon/Pokédex/Types/Dragon

There are 13 Dragon Pokémon. Of these, 3 are first generation, 1 is second generation and 9 are third generation.

Of the 13 Dragon Pokémon, only 4 are pure Bug. The other 9 are Flying(4), Psychic(2), Ground(2) and Water(1).

The type matching of the Dragon type hasn't changed, nor has the type matching of Flying, the only co-type of Dragon in the first generation Pokémon.

Notes

1. Prior to Generation 6 Kingdra is only weak to Dragon type. (The weaknesses of Water type, Electric and Grass, are canceled by Dragon type, and the weakness of Dragon type to Ice is canceled by Water type).
2. A few of these Pokémon are evolutions of non-Dragon Pokémon who are weak to some of Dragon's resistances (Water, Grass or Electric).
