It's also why most Pokemon are surprisingly small
>Sugimori: In the earliest days of Pokemon Red and Pokemon Green's development, I drew a piece of concept art. Even in those days, there were Pokemon that would let people ride on their backs like horse do, Pokemon that would take you to distant places like an airplane might, and Pokemon that would go everywhere with you as your partner. What really came out of that was the sense of each Pokemon's size. If they were as huge as dinosaurs, they couldn't really coexist with humans, so we used humans as a standard and settle down into designing the Pokemon to be a bit big or a bit smaller than people.>Sugimori: You see, even Pokemon appear before you as enemies to fight, they'll become your allies if you can catch them. That's the way they are constructed. Even if we had Pokemon that had frightening stories behind them or looked unsettling, we give them a sort of charm and depict them in a way that feel you could get close to them. This idea of "charm" is a basic part of every Pokemon's design. We give every Pokemon some sort of friendly aspect, and we've never made a Pokemon a complete villain in our stories.They use humans as the standard when designing Pokemon and go out of their way to make every Pokemon seem friendly
