>>13663286See, Charmander doesn't suck just because Brock and Misty can trounce him. There's no reason you should be fighting the first two gym leaders with only your starter, that's just full on retarded.
No, the reason Charmander sucks is because it gets SHIT for moves until it learns Flamethrower at level 34. THIRTY-FUCKING-FOUR. And that's in Gen 3. In first gen, you had to suffer all the way until level forty-six. So even if you only use Charmander/Charmeleon/Charizard to incinerate grass-types, good luck, because all you have to do it with is ember.
It learns moves at a better rate in the newer gens, but going through Kanto with this orange bastard back in the day was almost painful.
