Poison (type)

The Poison type has been criminally under-developed in the Pokemon games. It is super-effective only against Grass (many of which are dual Poison so neutralizes the effect). In the first generation it was also super-effective against Bug but this was changed. It fares a little better defensively but its best advantage is through status moves like Toxic.
