weedle for sure.
For real though, Snorlax. I'm pretty much there IRL, anyways!
Blastoise.
Because having cannons come out of your shell is just awesome. What you breath fire? Bitch I have CANNONS. You lose.
Blaziken, awesome kickboxing fire-bird. 'nuff said
Mew! Or Mewtwo! /thread
Though there is something to be said for Slowking..
Skarmory, I can be as hard as steal, yet light as a feather.
Cyndaquil was pretty bamf
Allakazam, badass with a cool mustache and an IQ of 5000.
And he still can't learn more than 4 moves. Q_Q
EDIT: And not to get too technical, but why is there still no Psychic move with over 90 power that doesn't belong to a legendary?! That's just lame!
Charizard.
No one can defeat Charizard and I remember as a kid if you got a Charizard card it meant instant popularity.
Mew. I'm a overpowered pink girly looking deformed cat. but still i'm the BEST pokemon ever.
