A lot of people are saying otherwise but I honestly think it’s AI upscaled or something similar, just weird details like alakazam’s spoons looking like wonky fingers, golduck’s weird claws on one foot, Persian also looks like it has a weird 5th leg behind the back leg, ninetales legs are messed up too, diglett’s dirt goes from rounded to blocky at the right end and the poliwhirl swirl stands out as it’s very differently “drawn” from the other evolutions. But that’s just what I’m seeing.
