Dragon-typePokémon are powerful dragons whose moves use the Special Attack stat and involve the use of claws and breathing dragon breath. They are very powerful creatures that are difficult to level up, and can learn many elemental type moves, such as SolarBeam and Thunder.
Not all dragon-like Pokémon are Dragon-type Pokémon; Charizard, for example, is a dual Fire-and-Flying-type.
One of the major weaknesses of Dragon types are Ice type Pokemon. The Dragon type is unusual in that it is also super-effective against its own type. The Ghost is the only other type to share this same property.
