Pokémon Walking Animations Found In Sun/Moon
Dataminers have unearthed an obscene amount of unused animations in the latest Pokémon games. Low-poly walking animations for all 802 monsters have been found in the game's data, leading to some speculation as to what they were for.
Currently the prevailing theories are that the content was cut at the last minute or that it was testing for the rumored Pokémon Stars. We'll keep you updated if any more information comes in.
It seems strange for Game Freak to spend all that time and money creating these animations only to throw them away. I believe this isn't the last time we'll see these walk cycles, though what they're for remains a mystery.
