>>11824613A lot of Pokemon are not based on nature...
There's inanimate ones, such as Chandelure.
There're ones based on urban legends, such as Sableye.
There's quite a few based on ancient myths, such as Gyarados.
And then there are Pokemon that are way out of the blue, like Giratina.
The Pokemon world is extremely diverse.
I used to play the YuGiOh TGC, so I know for a fact that the monster designs are generally pretty awful.
Mostly dragons and knights and shit that all look the same, just with more spikes and different color schemes.
