There are a great many warriors who have opined that poison is a coward's way to fight; very few of them, however, are also poison-type pokemon! Drapion's weaknesses and resistances can only be explained by them being both dark and poison pokemon, much like their larval form of Skorupi, and poison extracted from Drapion carcasses is remarkably potent and fast-acting. There can be no doubt that every Drapion possesses the ability to poison as surely as a Weezing or Muk; they simply refuse to use it, although it would make them beloved by trainers and assassins alike.
If questioned by one of those few who can bridge the language barrier between people and pokemon, many Drapion deny having the ability to poison others at all. When confronted with their poison use as Skorupi, they speak of it as a childish and shameful mistake, even if they at the time considered it a necessity to survive. Their continued evidence of internal poison is seen not as a method to poison others, but as a resistance to other poison-type pokemon. And this is a resistance they need. Drapion often turn their heads a full 180 degrees around, for they are terrified – some say paranoid - of being chased. The fraternity of poisoners, much like organized crime or armies, does not tolerate desertion, and many Drapion have indeed been attacked out of nowhere by other poison pokemon.
Yet the barrier between Drapion and poison use is entirely a psychological one. A few trainers are so skilled in rhetoric that they convince their Drapion that there is no shame in being a poison pokemon. When they do, they must also rediscover the poison attacks of the Drapion, lost for generations, to unleash these pokemon's awesome and terrifying power.
