The second somebody says, "There are only 150 Pokemon! (151 if you count Mew!)" I get the hell out of there before I start strangling that person aka Homer & Bart. I like Gen I as much as anyone else, but it's not a goddamn crime to love the latter games too. I like Giovanni and Cyrus, I love Mewtwo and Darkrai. Hell, my two all-time favorite Pokemon are from Gen IV and many mons I like are from Gen V. In fact, I can say with complete honesty that some Gen I Pokemon were boring from when I was 11 and are still boring today. (If it wasn't for Brock, I would've forgotten the Geodude family even existed)

Personally, I'd like to see Mewtwo blow them all to smithereens, whether in his regular or "awakened" form. That'd be satisfying.
