The Dragon-type is often considered an ancestral type as many Legendary Dragon-type Pokémon are revered as deities. Other Dragon-type Pokémon are frequently hard to catch and train. They also evolve late and are relatively rare. An interesting fact is that the stats of many Dragon-type Pokémon surpass the stats of other types of Pokémon.
Most Pokémon with the Dragon-type are usually reptilian in appearance, with a few exceptions being Charizard (who is Fire/Flying by default, but can become part Dragon-type if exposed to a Charizardite X Mega Stone). Other Dragon-type Pokémon lack draconic traits, such as Vibrava (who closely resembles an insect more than a dragon), Dragalge (whose overall design is based on the leafy seadragon, a type of fish), Alolan Exeggutor (with traits more close to a plant, more specifically a palm tree).
Eternatus (Eternamax) has the most HP, Defense, and Sp. Def of all Dragon-types (255 and 250)
Guzzlord has the highest HP of all obtainable Dragon types (223)
Baxcalibur has the most HP of all non-Legendary Dragon types (115)
Turtonator has the most Defense of all obtainable Dragon types (135). But when Duraludon holds the Eviolite, Duraludon has the highest Defense of all receivable Dragon types (173).

Mega Garchomp has the highest Attack of all non-Legendary Dragon types (170)
Mega Ampharos has the highest Special Attack of all non-Legendary Dragon types (165)
Mega Sceptile has the most Speed of all Dragon-types (145)
Noivern has the highest Speed of all non-Pseudo Legendary Dragon types when neither Dusk Mane Necrozma nor Dawn Wings Necrozma use Ultra Burst nor have the Z-Crystal Ultranecrozium Z (123)
They have no effect against the Fairy type because in certain mythologies, fairies' magic could dominate oriental dragons. While dragons were often immune to magic in European legends, it is a common theme in fairy tales that knights slay the dragon and for dragons to be weak to magic.
They're weak against themselves because only a dragon could overpower another dragon. It could also be that being a magical creature, they can only be defeated by another magical creature, hence the Dragon and Fairy weaknesses.
They're weak against the Ice type because dragons are reptilian creatures and reptiles are cold blooded (ectothermic), which causes them to become slow and lethargic when faced with cold temperatures, and is also probably a reference to the Dragon Quest video game series, where dragons are weak to ice.
The Steel type resists them because in legends, knights used armor of that material to defend themselves when facing a dragon. Strangely, they're not weak to the Steel type.
In Generation I, it is impossible to get super-effective damage from a Dragon-type move since the only Dragon-type move in Generation I was Dragon Rage, which did a fixed 40 damage.
No Pokémon can have a double weakness to Dragon (since the type is only super-effective on itself).
Mega Altaria is the only Dragon-type Pokémon that is immune to Dragon-type moves.
Dragon has the fewest non-damaging moves out of any type, with only 2: one of which is Kommo-o's signature move, Clangorous Soul. and the other is Dragon Dance.

Sinnoh is the only region that did not introduce a Dragon Type Specialist.
Johto had Lance return as champion, and Clair now has appears and makes her debut as the eight gym leader
Hoenn had Drake as the final Elite Four Member (you could call him The Elite Fourth Member!)
Unova had both Drayden and Iris as the eighth gym leader being version exclusive. However, in Black 2 and White 2, Drayden is the seventh gym leader and Iris has become the champion.
The Dragon type and the idea of "dragons" aren't the same in the Pokémon world, as some Pokémon which are not Dragon type sometimes are called "dragons" or used by dragon masters. These Pokémon are Horsea and Seadra (by their classification), Aerodactyl (by a man in Pewter Museum), Gyarados and Charizard (by Lance, especially in Pokémon Masters), Lugia (by a man in Ecruteak City), Lapras, Aggron and Archeops (by Iris), and Iron Jugulis (implicitly, being a robotic version of Hydreigon). There is also a Dragon Egg Group which contains some other draconic Pokémon.
Dragon is the most common type for pseudo-legendary Pokémon, with only two pseudo-legendary Pokémon not being part Dragon type.
Galar has introduced the most Dragon Pokémon with eleven with Regidrago being added through the Crown Tundra DLC, formally beating Unova's ten Dragon types.

Dragon and Ghost share some qualities. They both: originally had three Pokémon in Generation I, then gained only one more in Generation II, are the only types that are weak to themselves, and have one type immune to them and one type resistant to them.
In Generation III, all Dragon type moves were Cool moves.
Dragon is the most common type to serve as version mascot, with nine Dragon type Pokémon having served as mascots for ten games of the core series.
