I wouldn't say I'm a Pokémon Purist. Why you may ask?
Well, each generation brings with it many different Pokémon. And within those Pokémon, some I love, some I hate, and some I just can't fathom why. It doesn't matter which generation it is or was, it's the same with each to me.
And example would be with Generation 1, I loved Dragonite, but I could not stand Weezing. In the current Generation, I can't stand Crustle, but I love the look of Krookodile.
