Top Ten Pure Poison Pokemon
Arbok is overall the strongest pure poison type Pokemon because its one of the only pure poison Pokemon that could learn earthquake which could take out probably almost all of your opponent's Pokemon, plus it can learn moves such as stockpile, swallow, and spit up that will make it unstoppable except probably, when its opponents are psychic types that could levitate, some ghost types, and some Pokemon that could learn ground type moves, but what are the odds of that? Emma' Right?
Wait, why Koffing and not Weezing, isn't Weezing also a poison only type? because Weezing is much better than Koffing, and trumps Arbok any day. It's literally a living poison distiller, how poison like can you get? Arbok is just a cobra after all...
How come ekans isn't higher on the list?
