Fun Fact: most of the pokemon from the early generations are based on real life animals(whether extinct or still existing) while the rest are based on mythological creatures like dragons or japanese youkai. also many names where changed in english giving them a sort of a pun that describes them - for example charmander which is basically char(from charcoal) mander(salamander), however the translation of his japanese name is “human shadow” because its shadow looks human. On a side note, this is the only anime that i know of that the english song is much better then the japanese one - both in lyrics and music
