>>26788164Zangoose had been my favorite since Gen 3 - my bro, my senpai, what have you. But when X/Y came out, I kept finding myself fixating on Pumpkaboo. I found myself using it ingame, buying its merch, and eventually making it the subject of my first shiny hunt - I couldn't get enough!
Halloween is my favorite holiday, and I love things that are both cute and gothic/gloomy/creepy. Pumpkaboo fit all of those criteria and just stuck with me. Now its my number one favorite and Zangoose is my fourth.
Tyrantrum and Noivern share my number 2 and 3 slots. I've never really cared for Dragon's either way, but I do love Dinosaurs and Tyrantrum is the perfect mesh of Pokemon and Dino. Noivern just has a design that enchanted me from the get go. My only qualm is that you get Noibat so late in the game.
So I'd say that Gen 6 had some of the best Pokemon designs the series has had so far - so much so that three of its Pokemon replaced my top 3 favorites.
