Thanks!
Well, back in the 'old' days of Pokemon Red/Blue/Yellow (when I was heaps younger) I mainly thought of the 'cuteness' of the pokemon - of course, all three were rather cute.
I was never a squirtle fan really (dunno why)
Bulbasaur was my favourite for a while, but then, I gave charmander a go...
and it turned out to be just the most awesomest pokemon I could've picked!
Cause I had to train it up heaps to be able to defeat Brock, it made it so it was pretty strong early in the game, and that helped a bit later on.
So yeah, my Charmander obsession has just sort of 'stuck' ever since the beginnings of my pokemon journey. XD
