Dragonite realistic

Dragonites are very versatile-yet-hard to catch PKMN. They are valued for their strength and loyalty and have come to become a symbol of greatness to whoever posesses one.
They are of legendary proportions due to their rarity and low breeding rate. Dragonite are almost never seen in the wild, and their pre-evolutions are very rare either, but recently, their nmbers have been declining due to poachers hunting down Dratini for their valuable Dragon-Scales.
Dragonite bones are surprisingly light. The bone hystology is mostly trabecular bone, therefore its bones are extrmely fragile, but they are protected by thick layers of muscle and their extremely hard and scaly epithelium composed of hexagonal tightly-interlocking scales that function almost like chain mail. Dratini and Dragonair's scales are soft and aren't tightly interlocking, which makes them very vulnerable. However, Dragonite bones are very flexible which makes up for strong blows, and they regenerate constantly. But these bones are expecially hollow to allow for flight. Dragonite's massive wings are said to cause gigantic gusts and even twisters that will lift up most pokemon. It also has the capability to generate electricity as a defensive method, and they're able to breathe fire and ice.

However, for trainers, the only known potential weaknesses are ice, electricity that will impair the wings, or another Dragonite.
