I've really always loved Meowth. Also, I like Dunsparce. I have no idea why I like those two so much. Also, in my household, among me and my siblings, "Hoppip" was an obsessive inside joke for years because of how... stupid... it looks.
My first Pokemon favorite was Meowth. Just because I loved cats and was never allowed to have one when i was younger. Lol. But i am pretty much a fire pokemon lover at heart. I pretty much love the majority of fire pokemon. Because they are kick ass. The end.
Well, I'm completely in love with fire pokémon!
But my favorites include Ninetails, Moltres, Torchic, and the random Cubone and his evolve form ;p
And I will admit that I have a thing for Pidgeotto and Luxray :D
And just to randomly add, I prefer the 1st generation. Because the whole original point was that there is no animals, only Pokémon, so they seem so stay the truest to that :)
