Oh, I picked Charizard in Leaf Green. He totally kicks a**. I think he's on Pokemon: XD now. Might I recommend Gyrados or Starmie? Of course, Sharpedo would be your best one-shot Pokemon...
Once I realised I was actually sequence breaking, I gave my Raichu a bunch of battle experience (which included clearing out the Fuschia gym and Cycling Road). Took that Charizard out in one shot. cool
