Housefly
You’d be excused for thinking this was already a thing. Bug Pokemon have been realized as slugs in rocks and battery grubs, but those annoying, buzzing black pests that ruin every family barbecue? Not a single one in sight. Alola came fairly close by giving us Cutiefly – based on the bee fly, and yes that’s a real thing – but it lacks the swattability of a nasty old housefly. Even the lowly mosquito finally landed a role as Buzzwole, the muscular, horrifying behemoth of the Ultra Beasts.
If we can have a big, sexy mosquito, why can’t we have a housefly (it need not be big nor sexy)? To represent its general futility, it would have completely abysmal stats and appear en masse in sunny areas, or near the rear ends of equine Pokemon. You would learn to hate it even more than the detestable old Zubat, and eventually lament its very existence. Art imitating life, you see.
