What is your favorite Pokemon?

I have millions of those, but I'd have to say mine is either Gardevoir,Sceptile(both Gen.3) or Volcarona(gen.5)

My favourite Pokemon is a Jigglypuff as seen from above :D This is a tough one... Poooooossssssssibly Quilava. That's the first that comes to mind without thinking of specific examples (like my Blaziken from Ruby). It used to be Persian back when there were only 151 Pokemon, then Umbreon as soon as information on the Johto dex was released, and now Eevee, Umbreon, and Espeon together are my favourite Pokemon, but individually are only contenders for my favourite. My favourite 3rd-gen Pokemon was Gardevoir for a while (not for the reasons you're thinking if you're a perv). I have favourite Sinnoh Pokemon, but I only played through once, and that was a while ago, and haven't seen much of the newest generation (though Victini is utterly adorable, and if I'd had the money I would have preordered solely for him. Same gushing about Jirachi)... If you're going to count gut response for much, more than most common strength of impressions, favor of use, and other things that can be put down on paper, I'd say Quilava.
