While the creatures in Pokémon aren't real, that doesn't mean they're not based on real things or scientific concepts. Heck, there are even scientific concepts named after things in Pokémon, amusingly enough.
DYKGaming walks us through a bunch of fascinating facts about Pokémon and science in this video and if nothing else, it's harder not to appreciate Pokémon like Charmander after watching. Just makes me wonder what the story is behind a bunch of other Pokémon -- because who knows, maybe all the silly looking 'mon have a rich history behind 'em! Klefki does, at least.
