In particular, Fairies in ancient mythology are weak to "cold iron," which was old-timey speak for smelted carbon-iron, aka steel, being something completely manmade and not found in nature. Their weakness to poison, which in the world of Pokemon often represents pollution and unnatural chemicals is an extension of this weakness to manmade things.
