>>55988289the world of pokemon has two definitions for "dragon"
1. dragons, as in "big fire breathing lizards" (which is why charizard an gyarados are refered to as dragons), which is a term that likely came before the next one
and 2. Dragon Types, which are likely named after the culturally perceived power of dragons and refers to pokemon which resist grass fire water and electric moves and are only weak to its own type and ice (and now fairy too)
