You people look way too far into these things. The Pokemon rarely reflect the region inspiration as closely as you're making out. Unova was the USA, yet the legendaries were based on the Eastern concept of Yin/Yang. The legendaries might end up being norse inspired, but you're reaching SO damn far with that Gogoat shit. It's just a goat you can ride, Unova had an Ice Cream Pokemon but that doesn't have much to do with Yin/Yang.
