I feel like the designs have just been getting sillier as they began running out of ideas.
Don't be silly, there's no way a Gen 1 Garchomp would have been that sharp and angular!
OT: Eh, I don't mind the idea of the designs getting simpler. Some of the later Pokes have been getting a little crazy looking.
While you're at it, can we get some Fairies that aren't all pink and girly?
