For me, my first great pokemon memory was sitting down to watch the show for the first time. It was late '98 and the craze was in full swing so I was curious to know what all the hoopla was about. Also, for some odd reason, I wanted to learn the names of all the cute and interesting creatures that I was seeing.
So, I figured that the best way to learn was to watch the anime, and learn I did! By watching the episode, "Ash Catches a Pokemon" I learned how and had no need for that old man just outside Viridian forest when I started playing the red version in late '99. I remember my starter being a Charmander because Charizard was, and still is, one of my favorite pokemon.
Though, I must admit that my continuous fascination with Mewtwo started early, basically when I watched that first episode from beginning to end and saw him flash across the screen at the very start of the 1st season intro. I can distinctly remember thinking; "Okaaay...there are purple space kangaroos involved?" From that moment on, I did what I could to find out the identity of that "violet alien marsupial". And even when I did find out who he was, he continued to be this mysterious enigma up until I saw the first movie.
