>>43645648>Grass - PlantGrass is perfectly fine. Its type matchups are based around how specifically grass responds to elements (e.g. weak to fire, absorbs water, etc). It's also more abstract than "plant" and can cover plant-like organisms like mushrooms.
>Dark - MischiefDark is fine as it means "dark" in the sense that 9/11 jokes are dark, e.g. things that are edgy or back-handed, which literal darkness also just so happens to fall into.
>Flying - AirCan't argue with this one.
>Fighting - ???Brawl type maybe? All Pokemon fight in battle so it does sound kinda redundant as a type name.
