- Dragonair is long 13'1'' (3.99m) but only weighs 36.4 lbs (16.5kg) as well as being extremely thin and slender.
- Dragonite is shorter 7'3'' (2.21m) and yet weighs 463 lbs (210kg) as well as being quite... chunky.
It makes sense that a Pokemon would grow as it evolves - in order to become stronger; it just seems that Dragonite's grew width ways and not length. In fact mass from the tail/ body of Dragonair went into making Dragonite wider also. This makes sense as it would make Dragonite more bulky - increasing it's stats in HP, Special Defence and Defence - as well as putting more weight behind it's hits - increasing it's Attack stat - and, by growing wings, Dragonite has become faster due to an increase in manoeuvrability. It's Special Attack stat may have increase through an increase in spirital power an self-belief obtained through evolving - Dragonite realises it has become more powerful.
The Giant Dragonite is not fake but a giant of the Pokemon world. There have been others like Giant Tentacruel and Giant Slacking
- Slacking is usually 6'7'' (2.01m)
- Tentacruel is usually 5'3'' (1.6m)
In fact, Pokemon sizes in the anime vary much like in real life:
This is not the case in the games as the programming for stat differences between the same Pokemon would take a lot of time an not add to the gaming experience that much - therefore it was largely unnecessary. Although, Game Freak are striving with Pokemon nowadays and Gourgeist has the first evolutionary line of Pokemon with varying sizes.
A lot of Pokemon sizes and weights are illogical though and there are many YouTube videos on the matter...
