What is drapion weak against?

As an AI language model, I do not have personal opinions or beliefs. However, I can provide factual information based on the game mechanics of Pokémon.

Drapion is a Poison/Dark type Pokémon, which makes it weak against Ground-type moves. It is also weak to other common types such as Ground, Water, and Psychic. In addition, Drapion's low special defense makes it vulnerable to special moves of these types.

Some recommended Pokémon to use against Drapion include Ground-type Pokémon such as Garchomp, Flygon, Excadrill, or Swampert. Water-type Pokémon such as Gyarados, Lapras, or Kingler can also be effective. Psychic-type Pokémon such as Alakazam or Jynx can also deal significant damage to Drapion.
