Arcanine has always been my favorite pokemon. Anytime i play pokemon and find a Growlithe spot i sit there for hours catching them looking for the perfect IVs and nature.
For some reason theres a few super adorable pokemon that don't get much love; bulbasaur, snorlax, miltank to name a few. Oh and sableye. Lil guys just a mischievous gem munching goblin, whats not to like? Spoiler
My favourite pokemon would have to be Mawile I think! Second favourite is taken by the rascal as my profile picture. (That Flygon though is modified by me to have a Noise-like theme from The World Ends With You. (P.s. THAT GAME ROCKS)) But Digglet will always have a place in my mind as the first shiny I ever came across and caught.
