Evolves from Wailmer
Wailord is one of the most ridiculous Pokémon of them all. It evolves at level 40 from the relatively tiny Wailmer, but Wailord is anything but small. In fact, it's the biggest Pokémon of them all (so far, at least).
Yes, it's bigger than the Pokémon that created the universe, the one that's in charge of earthquakes, and the ones that are literally dinosaurs. And the most ridiculous thing is that it lives in a tiny ball that you can carry around.
