Dragonite from Dragonair makes a lot of sense because Japan likes to associate dragons as being kind, gentle, and aquatic.
Magikarp to Gyarados makes sense because Gyarados is an aerial, serpentine Pokemon. Japan has windsocks named after koi (the fish Magikarp is based off of), which match the shape and "flying" aspect of Gyarados.

If you knew about the Japanesee folktale about a fish swimming up a waterfall to become a Dragon, you'd know Magikarp to Gyarados makes sense. In fact there was an anime episode centered around this very legend.
Chinese but yeah I liked that episode.
Personally I liked Tracy
