Bug Type Explained
Bug hits Grass, Psychic and Dark super effectively, but seven types resist Bug attacks — tied with Grass for the most. Defensively it resists Grass, Fighting and Ground and is weak to Fire, Flying and Rock.
Against a pure Bug Pokémon, lead with Fire, Flying and Rock moves and avoid Grass, Fighting and Ground. Against a Bug dual type the answer changes, because the second type can cancel a weakness or stack it into a 4× hit — use the Pokémon type calculator to check any exact combination.
