>>54131206I'll second that, Gen 2 Entei is probably the closest thing to a "spook" encounter in the series, Raikou close behind. Their sudden appearances mean you brain is set to expect a smaller wild Pokemon but suddenly you get one of these corner-filling giants with their loud cries instead. I could imagine Shudo's thought process being "Damn, can I use THAT one for the next movie?"
Pic most certainly not related.
