Oy, you too? Maybe there's something about me that says "this guy like Munchlax" or something. Nah, I have no favorites after the 3rd generation, though I do like some 4th gen designs, like Buneary. I just have no attachment to any of them.
But to reiterate, a lot of my favorites are from Gen I, mostly for memory reasons than out of some biased preference. Also, I think the Nido family sans Nidoking are the only familial based favorites I have, so it's not a good idea to start listing off of family members once you find a new favorite.
Alright. Similar, not a dragon, not Metagross and broad stats. Blastoise?
