I have to say that there are lots of 5th Pokémon which don't seem "real" Pokémon to me. Look at Klink. Well, Klink is admissible, but look at Klang and Klinklang... Those are not Pokémon, in my opinion. The same happens with Cryogonal... what is that?
I've come to think that the way of drawing new Pokémon is changing and that's why they all look a bit different now. It has to be that.
