Fighting, Bug, and Fairy moves are good against Dark-type Pokémon.

What is good against Dark type?

In the mainline Pokémon games, Dark types are weak to:

• Fighting-type moves (does super-effective damage).

• Bug-type moves.

• Fairy-type moves.

Dark types also usually resist Psychic- and Ghost-type moves, so avoid relying on those for damage.

Simple example

If you’re fighting a Dark-type like Tyranitar or Weavile, using a strong Fighting move (Close Combat, Aura Sphere, Dynamic Punch, etc.) or a Fairy move (Moonblast, Play Rough) is often the fastest way to knock it out.
