I like quite a few so it really depends on what you mean by favorite. The ones I used most in Battle (before training my other pokemon that is) are Archeops and Zebstrika. If Loving pokemon makes me a child, then I'll gladly let you fuck off. xD by that Logic a majority of the worlds population under the age of 30 is childish.
mine is evee or mew or mewtwo anyway i like rare pokemons. I miss those days when i play pokemon all the time then forgot to save. It makes me cry for a long time
I mean, I'm pretty sure there's only a thin line of reality between us and them Which I plan to break
