Venomoth

Venomoth is usually considered inferior to other Pokemon, due to its NU status and Bug typing. If one looks past these "disadvantages", however, one will find that Venomoth can prove to be a consistently useful team member. This fragile-looking moth has many assets, the most prominent being Tinted Lens, an ability that helps Venomoth hit so-called counters hard, by turning 4x resistances into 2x resistances and 2x resistances into neutral hits. Tinted Lens gives Venomoth unresisted coverage against every UU and NU Pokemon except Shedinja. Combine that coverage with respectable Special Attack and Speed stats, and Venomoth becomes a force to be reckoned with. Venomoth's usefulness doesn't end with offense, though. It can also prove to be a good supporting Pokemon, boasting 4x resistances to Grass- and Fighting-type attacks, Sleep Powder, Toxic Spikes, Stun Spore, Baton Pass, and Sunny Day. With a number of ways to fit into a team, Venomoth is living proof that Bug-types aren't as weak as they are commonly thought to be.
