Oooh, it's really hard to pick just one! but I guess if I had to, it'd be Sylveon. A close second is Teddiursa. I also kind of love most fairy types.
Gengar is my favorite, through and through, but Mimikyu gives a bit of competition, I'll admit.
especially Ditto Mimikyu. it's a bootleg of a bootleg Pikachu. I love it.

Porygon and Aegislash are my big two. I love a ton of them, though.
VULPIX 1000% Vulpix. I have a big popfunk figure of vulpix next to my tv that I LOVE
I can't pick there's a lot of them! Especially all the cute ones ^-^
It's so hard to choose, but I think it would have to go to Tyranitar.

Mudkip has always been my favorite, but i like a lot of pokemon it's hard to choose.
I don't know if I can choose a favorite... I like a lot of them including Charizard and Tyranitar
Honestly my favorite was Ivysaur <3 His coloring with the darker tones in there compared to bulbasaur and even venusaur was awesome!
