Battle notes

Bug / Grass intensifies Fire, Flying into a 4x weakness, so those attacks are the cleanest punish.
Because dual types multiply both defensive matchups, Fire attacks (4x) is the most direct way to punish this combination under the modern Gen 6+ chart.
Avoid defaulting to Grass, Ground, Water attacks unless you have a specific reason; this typing resists or blocks those lines of play.
This exact typing exists in the current National Dex, so the matchup is useful for real Pokémon pages and team planning.
